On July 22, the "Power Distribution Cabinet with Design Defects" reported by the 70228 Drilling Team of the First Drilling Company of Sinopec Zhongyuan Petroleum Engineering Company stood out among 405 safety diagnosis suggestions and was rated as an excellent safety diagnosis suggestion by Sinopec Zhongyuan Petroleum Engineering Company

“Due to the recent rains, we have strengthened the safety inspection of electrical equipment
.

It was found at the inspection site that the switches on the old explosion-proof power distribution cabinet did not have a locking device

There are many electrical equipment in the drilling construction site, the skill level and safety awareness of the operators are uneven, and there are many hidden dangers of electrical misoperation
.

In order to minimize the hidden dangers of misoperation, the team set up a research team, on the one hand, in accordance with the electrical work safety operating rules, to ensure that the operation is in accordance with the procedures, and the supervision is carried out; on the other hand, from the perspective of achieving the intrinsic safety of the equipment, it conducts research and improvement of the power distribution cabinet.

The specific operation of improving the power distribution cabinet is: adding the power switch locking device only needs to process a suitable length angle iron as the support of the locking device according to the effective length of the switch on the power distribution cabinet and the position of the fixing bolts of the power distribution box cover plate, and It is fixed on the fixing bolts of the cover plate of the distribution box
.

A locking pin hole is set at the limit of the switch knob on the power distribution cabinet, and a hole is punched and positioned on the bracket of the locking device to ensure that each switch can be effectively locked
