What does the electrical safety inspection include?

Electrical safety inspection includes inspection of distribution room, distribution box, distribution perimeter, cables, current transformers and protective equipment.

A, transformer room inspection

1, whether the power distribution cabinet is overloaded, whether the indication of voltage and ammeter is normal, whether it is within the specified range, and whether the power distribution cabinet is seriously dusty.

2. Whether the switch intersections and electrical connection positions are hot or discolored.

3. Whether the capacitor cabinet is overheated, whether it leaks oil, and whether the ammeter indication is normal and reliable.

4, cable, bus insulation is damaged, poor contact whether there is overheating.

5, operation ticket, operation procedures are on the wall, signs are ready.

Second, the distribution box inspection

1, whether the appearance is intact, whether it is corroded, whether it is seriously dusty, and whether it is reliably grounded.

2. Whether the air switch is sensitive, whether the knife switch is in good condition and whether the fuse is configured according to the specified value.

3, leakage protector switch is in good condition, the action is sensitive and reliable.

4. Whether all electrical connection points are hot or discolored.

5, cable, wire insulation damage.

Three, distribution perimeter and cable inspection

1, whether the overhead line insulation is damaged, and whether the bracket is corroded and moldy.

2, cable insulation sheath is in good condition, with or without aging, leakage, overheating.

3. Whether the cable tray is corroded, damaged or fallen off.

4, electrical connectors with and without heat discoloration, insulation bandaging with and without looseness.

Four, electrical equipment inspection

1, whether the shell is in good condition and whether the grounding wire is reliable.

2. Whether the cable insulation sheath is damaged.

3, leakage protection switch are in good condition, with or without corrosion phenomenon.

4, whether there is a serial number, regular inspection data is complete.

V. Inspection of Current Transformer

1, whether there is discharge, overheating or abnormal sound.

2, a side lead, line card and secondary circuit components should be in good contact.

3. The shell grounding and secondary circuit grounding should be good.

4, transformer withstand voltage test regularly.

Six, protective equipment inspection

1, whether the electrician on duty wears insulating shoes as required.

2. Whether each transformer room on duty is equipped with safety protection articles such as insulating boots and gloves.

3. Whether insulating boots, gloves, etc. Conduct regular tests according to regulations.
