Power supply safety work ticket and operation ticket management method

Chapter 1 Work Tickets

Section 1 General section of substation and line work ticket

Article 1: When performing normal maintenance work on the power supply equipment, all need to do security measures

Work tickets should be used.

Article 2: Common work tickets are divided into: first and second work tickets for substation, power line number

First, a kind of work ticket. The format used is as follows in the "Safety Regulations":

1. Fill in the work ticket:

The work of the first type of work ticket is:

Working on high voltage equipment requires all or part of the power outage;

Work on circuits such as secondary wiring and lighting in a high-voltage room requires power-off or safety measures for high-voltage equipment.

The job of filling in the second work ticket is:

Live work and work on the outer casing of a live device;

Control panel and low voltage switchboard, distribution box, power supply line work;

Work on the secondary winding circuit, no need to power off the high voltage equipment;

Work on a rotating generator, an excitation circuit of a synchronous camera, or a rotor circuit of a high voltage motor.

Non-duty duty personnel use phasing with insulation rods and voltage transformers or use a clamp-type ammeter to measure the current in the high voltage circuit.

2. Use of power line work tickets:

The job of filling in the first type of work ticket is:

Work on the stop line;

Work on the distribution transformer rack in all or part of the power outage or in the distribution transformer room.

The so-called total power outage means that all power lines supplied to the transformer gantry or distribution transformer room have been disconnected.

The job of filling in the second work ticket is:

Live working

Work on an electric line tower;

Work on the distribution transformer rig in the row or in the distribution transformer room.

Article 3: The work ticket is filled in by the issuer. Sometimes in order to reduce the workload of the work ticket issuer, the work person in charge can also fill in the work ticket of the class.

Article 4: Work tickets should be filled in duplicate with a pen or a ball pen. They should be filled in correctly and must not be modified arbitrarily. If there are individual words that need to be modified, they should be clearly written. A work ticket modification must not exceed 3 words.

Article 5: Fill in the work ticket should use language that can accurately express the meaning and conforms to the national language standard.

Article 6: The personnel listed on the work ticket shall be examined and approved according to the responsibility, and the signature shall be complete and the writing shall be neat.

1. The work ticket shall be issued by the issuer, and the work ticket filled out by the person in charge of the work shall also be issued by the issuer.

2. Under normal circumstances, the work place on a work ticket is limited to one electrical connection part. If the construction equipment belongs to the same voltage, is located on the same floor, and stops power transmission at the same time, and does not touch the live conductor, it allows several electrical connection parts to share one work ticket.

3. In the following cases, the person designated by the company to issue the work ticket shall issue a work ticket, and the duty officer shall perform the work permit formalities. The job ticket issuer is only responsible for the necessity of the work, the safety of the work and the correctness of the safety measures listed on the work ticket. Before starting work, the guardian will provide safety education to the staff and explain the precautions.

The external unit with legal person qualification shall repair, anti-corrosion or install the substation contract equipment.

Infrastructure construction requires the equipment in operation to stop running.

Install the unit to handle equipment defects that are newly commissioned.

4. A substation or a line can be sent to a work ticket for all power outages, but the work content should be detailed. When several teams work at the same time, the work ticket can be sent to a general work person in charge, and only the person in charge of each class is filled in the work class member column.

Article 9: One of the two work tickets must be kept at the workplace regularly, and the other person in charge of the work will receive the contract and the other will be handed over by the duty officer. The duty officer should record the work ticket number, work assignment, license start time, and completion time in the operation logbook.

Article 10: Job Leader

1. Personnel approved by this Council for publication.

2. When an external unit with legal person qualifications goes to the substation for contracting civil works construction, equipment maintenance, installation, anti-corrosion or commissioning, the person in charge of the work shall be designated by the foreign unit, and the list shall be submitted to the company safety supervision for safety qualification beforehand. The supervisor forwarded the list to the substation.

3. Changes in the person in charge of the work:

During the work period, if the person in charge of the work temporarily leaves the scene for 2 hours, the person responsible for the work shall be updated by the person who issued the work ticket. The two person in charge of the work shall make the necessary handover. The change of the person in charge of the work can only be processed once. The change of the person in charge of the work ticket of the second type of work ticket is recorded in the "Remarks" column.
