Summary of safety work in the first half of 2012

In the first half of this year, the security situation was very serious. Four 220KV substation power grid accidents and four equipment-type obstacles occurred one after another. The circumstances of the accident, the causes, the problems and the next work arrangements are summarized as follows:

First, the accident situation and analysis:

Grid accident:

On January 14, 2004, the 220KV Makou station was tripped due to mis-wiring in the measurement personnel's test, causing the 1# main transformer differential protection action to trip.

At 23:43 on March 31, 2004, due to the error in the design of the protection device, the composite voltage was negatively sequenced, and the red 2# main transformer 110KV side switch red 21 tripped, the coincidence was unsuccessful.

At 16:47 on May 4, 2004, the 220KV Yao 10 switch C-phase porcelain bottle was flashed on the mechanism box, causing the 220KV Yao 01, 10, 07 switch to trip.

At 21:25 on June 20, 2004, the operator of 220KV Mengze accidentally entered the electrified interval, and the 220KV busbar with the electrician was accidentally operated, and the whole station was cut off.

2. One type of equipment obstacles:

At 15:52 on February 10, 2004, the 220KV Yaoxiao line was covered with ice by wires and insulators, causing a short circuit between B and C, and the test was successfully sent.

At 6:12 on March 3, 2004, the P phase of the Peng 01 switch of the 220KV Pengwan substation was tripped due to the grounding of the secondary cable.

220KV Jidong Substation 刁01 switch tripped, coincident success

At 11:46 on May 6, 2004, the 220KV刁01 switch split-phase trip signal component B tripped and the card was re-closed, and the coincidence was successful.

At 11:21 on May 20, 2004, the fishing rod was discharged too close to the wire, causing the 110KV bear to trip once in a zero sequence, and the coincidence was successful.

3. Analysis of security situation:

Judging from the accidents and the types of obstacles in the first half of the year, the security situation of our bureau is not optimistic. In particular, the 6.20 accident revealed that there are still many hidden dangers in the safety production of our bureau, which are manifested in the following aspects:

The safe operation of the main power grid is not effectively guaranteed. Main grid accidents, frequent types of obstacles, 4 power grid accidents, 4 types of obstacles, and almost all 220KV substations in the whole area were involved. The grid accidents have increased significantly compared with last year, affecting the power supply of the next-stage substation and the loss of power.

Relay protection, automatic devices, and secondary circuit failures cause misoperations. The causes of the secondary failure include poor design, unqualified quality, and miswired, reflecting the fact that the ordering and acceptance are not strict, and individual workers are not familiar with the field equipment.

Violations of laws and regulations have been repeatedly banned, and even human-induced mishaps have occurred. Explain that some of our leading cadres and employees are indifferent to their safety awareness. They have no rules to follow, cannot implement rules and regulations conscientiously, have poor sense of responsibility, and are unscientific in management and not in place.

Equipment is less resistant to natural disasters. Thunder, strong winds and natural disasters such as ice blasting in the first half of the year are an inspection of the ability of natural disaster resistance of equipment. Lightning protection has always been a focus. Compared with last year, the damage is reduced, but the prevention of other natural disasters also needs Take further scientific and effective means.

The protection of power facilities and the promotion of power safety need to be further strengthened. Through unremitting efforts and a large amount of investment, the environment of power facilities has improved. However, there are still many problems in housing barriers and safety warnings. Buildings are fast and difficult to control. The handling of resistance is large and coordination is difficult.

Rural low-pressure accidents have occurred from time to time. After the network reform, the quality of the rural power grid has been greatly improved. However, due to the gap between the management, the personnel and the safety knowledge, and the actual requirements, the accident has occurred. The provincial bureau has issued the regulations on rural low-voltage safety management. ", the bureau will work out the corresponding management measures and implementation rules as soon as possible.

Second, the first half of the work review:

In response to the above-mentioned accidents, our Department of Security mainly focused on the following six aspects:

Seriously investigate and deal with accidents, formulate preventive measures, and urge the implementation of rectification.

After the incident, under the leadership of the Bureau of Public Security, seriously investigate the accident, analyze and discuss, and find out the cause of the accident. A special meeting was held for the relay protection misoperation organization, and the substation test station was urged to strengthen the daily inspection and replace the unqualified relay. In particular, after the occurrence of the 6.20 accident, the emergency notice on the current safe work was promptly issued, and the overall safety and general discussion activities were carried out, and the "Protection Regulations for Preventing Electrical Misuse" was issued again for the management of the master key. Special box for universal key storage.

Actively carry out safety inspections and safety production months:

According to the safety work regulations and the unified deployment of the superiors, in April, the safety inspections focusing on the “five investigations” were carried out in an overall manner, and the problems identified were promptly reported, and the list was classified and urged to be rectified within a time limit. In June, a safety month event was held with the theme of “Implementing a Safety Production Law and Everyone Everything Is Safe”. Carefully arranged, organize the county and city bureaus to use various media to vigorously carry out safety knowledge propaganda, and unified the street to preach and answer questions on June 8. According to incomplete statistics, 5,000 slogans were posted, 50,000 safety pamphlets were issued, and 5,000 copies of the Safety Month Knowledge Contest were answered.

Actively carry out county-level safety evaluation work by scientific means

At the beginning of the year, the Municipal Bureau held a mobilization meeting in Hanchuan. Deputy Director Tu Qi gave a detailed explanation on the significance, purpose and specific requirements for carrying out county-level security assessment work. The Hanchuan Bureau of the pilot unit quickly started its work according to the county-level safety evaluation standards and the requirements of the municipal bureau. After reporting the self-assessment materials, the expert group of the municipal bureau conducted a four-day security assessment work for the Hanchuan Bureau. Reported to the provincial bureau, the next step will be to meet the provincial bureau expert group review, and carry out county-level security appraisal work in the district.

Implement “digital filial piety” to establish a secure management network system.

With the cooperation of the information center, install and use the multimedia system of security management, education and examination, improve the homepage of the updated security department, promote the use of EMAIL communication, research and develop the “instant monitoring system for county-level power grid accident trips”, and implement online through regional network and INTERNET. Safety information exchange, trial online safety test, and instant grasp of county-level power grid accident trips.

Strive for government support and carry out power facility protection work.

On May 22, Vice Mayor Li Jinping hosted a conference on the protection of power facilities in the city. In the joint eight departments of power facilities protection work, the “Opinions on Further Strengthening the Protection of Power Facilities” was issued, and the power sector opinion column was added to the building approval report form to control the housing barrier from the source. In addition, the company invested funds to improve the protection of power facilities, installed nearly 10,000 color-coded pipes along the road, and handled problems such as Xiaochang housing barrier and Hanchuan roadblock.

Increase on-site supervision and establish a sound safety system

In accordance with the spirit of “creating non-violation of corporate activities”, we continued to strengthen on-site safety inspection and supervision, and persisted in unremitting efforts to arrest violations. In the first half of the year, we investigated and dealt with more than 20 violations of discipline and discipline, and notified the illegal personnel and relevant leaders of the criticism and imposed fines or laid-off treatment. The suppression of violations of personnel will be reported and rewarded. In order to improve the rural low-pressure safety management system, the “Low-Volume Two-Ticket Management Measures” was issued in accordance with the archives of the provincial bureau. 6.20 After the accident, the "Protection Prevention Management System" and the "Triple" Work of the Leading Cadres were formulated in a targeted manner.

Third, the main problems:

Some people have a lack of security awareness, poor self-defense ability, and business needs to be improved. Leading cadres, especially the station directors, focus on management and construction, ignoring safety production .

In the implementation of the safety responsibility system and various management systems, there are many forms, less content, more words, less work, more arrangements, and less effective.

In the use of new products, new equipment, and new technologies, the technical skills of personnel cannot keep up, and they are not familiar with the performance of new equipment and master the correct use methods.

The low-voltage safety management of rural power grids needs to be strengthened, the institutions are not perfect, the system is imperfect, and there is no special person full-time responsibility.

Fourth, the next step of safety and security work

We learned the lessons of 6.20 accidents, carried out the “five investigations and five observations” activities, and supervised the implementation of the “Emperor Notice on the Effective Work of Safety Production ” filed in [Xiaodian 43] and the fax spirit of “Strengthening the Safety Production during the Current Flood Control Period”.

Starting from the system, standardizing the provisions of the “three-fold” work leading cadres in place, preventing the management of mis-locking devices, implementing the “Regulations on Rural Low-voltage Safety Management”, and implementing the first and second work tickets and operating ticket systems for low-voltage operations.

Further carry out activities to create non-violation of corporate activities, focus on standardizing people's behavior, increase on-site supervision, increase penalties for violations of discipline and discipline, and resolutely put an end to personal injury and death. In the prevention of personal injury and death, we must resolutely implement the work ticket system, the work permit system, the work guardianship system and the construction work ticket, and focus on the analysis of dangerous points in order to prevent electric shock, fall from high altitude, and prevent broken bars.

To strengthen the stability of the power grid, we must resolutely put an end to the "three mistakes" of relay protection and the recurrence of vicious misoperations and the occurrence of transmission line accidents. The dispatching department should not make a mistake and make a mistake. The maintenance and repair unit must conscientiously implement the annual inspection plan, monthly inspection and maintenance plan, ensure the quality and process of maintenance, and the operating unit must implement the equipment inspection system, especially the inspection of 35KV and above transmission lines and 6~10KV distribution lines to ensure the inspection cycle. To ensure that the patrol is in place, the second guardian of the switch operation and the master key use program are strictly implemented according to the system. When the master key is not used in accordance with the regulations, the operator and the guardian deduct 1000, and the stationmaster 2000, the unit does not participate in the evaluation.

Increase the intensity of personnel training. Organize a backbone safety training course, focusing on the "Safe Production Law", the filling of two tickets and the analysis of dangerous points in various construction operations.

Implement “Digital Xiaodian” and cooperate with the information center to establish and improve the security management network platform of Xiaogan Power Supply Bureau, and promote and use the power grid fault record program of county-level power supply enterprises.

Further carry out the safety evaluation work, and run the provincial government to test the safety evaluation of county-level power supply enterprises in Hanchuan County, and promote it within the city.

Grasping the on-site safety management of the “two networks” transformation and finalization stage, especially the safety supervision of the whole process of county-level city network transformation.

Strengthen the protection of power facilities, increase publicity, supplement and improve various signs and warning signs, no new housing barriers and roadblocks will occur during the year, and the handling of tree barriers should be timely.

10. Supervise the completion of the 2004 “Two Measures” plan.
