3, equipment explosion and integrity check quality score sheet

V. Judging rules

1. Except for the rating items listed in the score sheet, other items are not included in the rating.

2, the wiring process time is 20 minutes, more than 30 minutes this item gets zero points.

3, the wiring process, 30 points per session plus 1 point, the time is greater than or equal to 25 seconds, 30 seconds to count; deducted 0.5 points for every 30 seconds. If the timeout is greater than or equal to 25 seconds, the time is 30 seconds.

The precondition for the extra points is that all wiring items must be completed, and the unfinished wiring process does not score. No points are added during the festival.

The precondition for the deduction is that the wiring process must be completed within 20 minutes to 30 minutes.

4, find troubleshooting, detonation and good inspection processing for a total of 25 minutes, more than 30 minutes this item gets zero points.

5, find troubleshooting, detonation and good inspection processing, add 30 points per section for 30 seconds, the time is greater than or equal to 25 seconds, press 30 seconds; deduct 30 points for every 30 seconds, more than When the time is greater than or equal to 25 seconds, it is timed by 30 seconds.

6. Use this accessory to cancel the qualification of this competition. You can use your own, homemade tools related to the game.

7. The contestants raised their hands to announce that they must leave the arena immediately after the game is over, and they are not allowed to continue or operate twice.

11. Except for the number of written faults, self-inspection, nature and location of the fault, the time for the completion of the “assessment project completion requirements” will not be added, and the score will still be scored according to the “assessment project completion requirements” and the score sheet.

Six, the status of the game

1, wiring process

All are well-closed switches. The upper cover of the switch wiring chamber and the internal bolts and nozzle bolts are tightened and in good condition at the factory.

Unify a spare wiring cable, sealing ring, etc.

For safety reasons, the power supply is not connected before and after the wiring process, but the competitor must operate with the power supply.

2, troubleshooting

The main power supply has been switched on before the race, but there is an air switch to isolate it.

Operate the switch ground wire to the main ground.

Before the troubleshooting, the upper cover of the switching power supply wiring compartment is bolted, and the incoming power cable is connected.

At the same time, the game is equipped with a faulty JDB-225-A electric integrated protector, intact electronic components, relays, vacuum tubes, cords, fuses, fuses and other uniform objects.

3, explosion and good inspection

The switch detonation and integrity check is performed synchronously with the fault check, and is manually set in the fault switch together with the fault.

VII. Assessment project completion requirements and scoring principles

1, wiring process

Complete the requirements:

Complete the connection of a rubber cable on the load side.

Before and after wiring, the wiring compartment upper cover, internal wiring bolts, nozzles and crimping plate fixing bolts are all tightened.

Grading principle:

In the competition, the contestants must meet the requirements of the judging rules for the connection of a rubber cable. If the person is not required to complete, the game will be zero points, and the time will not be added.

2, find troubleshooting

Complete the requirements:

All four fault points that are required to be set are excluded. The same group of fault points are the same, the fault points between the groups are different, and the fault points detected and processed should be the ones given by the fault point setting group.

The instrument must be used for troubleshooting. It is strictly forbidden to use the shorting method to check the fault.

After the fault is checked, the switch shall be subjected to a live self-test and the set load of the evaluation group shall be set and recorded. After the operation is completed, write out the number of faults, parts, fault causes and phenomena, otherwise deduct points.

Grading principle:

If all the troubleshooting points are processed, the scores will be scored according to the score sheet.

Participants will be deducted 20 points for each failure point, and the remaining points after deduction will be evaluated according to the scoring standard.

If the fault point is not excluded, this item will have zero points.

If the fault points are not completely excluded or cause other faults, the points shall be deducted according to the scoring standard, and the savings time shall not be added.

3, explosion and good inspection

Complete the requirements:

The four places that are required to be set are not destroyed or are not completely detected and processed. Explosion and in good inspection and record filling shall be subject to the settings set by the personnel of the setting group. Grading principle:

The switch detonation and the integrity check processing score are included in the total score of the actual operation, accounting for 20% of the total 100 points before the actual operation score, that is, 20 points.

5 points for each check, handling, or incomplete deduction. Fill in the inspection, the processing record is incorrect, and deduct 5 points in one place.

The switch is out of blast and in good condition for a total of 20 points.

Eight, assessment quality target content

1. Speed ​​and proficiency, proper use of tools and tools.

2. Wiring technology and explosion-proof performance, tool accessories placement and civilized hygiene.

3. Whether it is operated according to the operating procedures, whether it hurts others, self-injury and damage to equipment and accessories.

4. Fault analysis, judgment, search and processing capabilities.

5, explosion-proof switch explosion and good inspection ability and processing capacity.

Nine, fault setting type

1. The type of fault may be wiring, integrated protector fault, etc.

2. There are 8 different types of faults in the low-explosion switch. Each type of fault sets 4 fault points for each low-explosive switch.

3. Because each type of switch fault is not the same, when setting the fault, the fault difficulty level should be set as close as possible, and the fault setting personnel should try to balance the fairness.

X. Assessment project score description

1, wiring process

Each item in this rating can be deducted into a negative score, and the total item is deducted to zero.

2, find troubleshooting

Each item in this rating can be deducted into a negative score, and the total item is deducted to zero.

3, the switch is out of explosion and in good condition inspection and treatment

This item is checked for one or less points for each less inspection, and 20 points are deducted.

11. If there are serious defects in the game, it shall be replaced by the on-site assessment and ruling. Strictly implement the safety operation procedures. If the operation rules are seriously violated, the qualification of this item shall be cancelled.
