First of all, when the transformer is faulty, we must cut off the power supply of the transformer through abnormal methods for the first time, and many major electrical fires and electric shocks are caused by the main gate is not closed. Now let's take a look at what to do.
1. Power failure: When the low-voltage circuit is overhauled, the power supply should be disconnected and the melting electrical appliance should be removed
2. Electrical inspection: The electroscope ensures good operation, selects an electroscope with appropriate voltage level, and separates the electrical inspection on both sides of the outgoing line;
3. When the power is cut off due to the line or user maintenance requirements, the personnel on duty should adopt safety measures, and then notify the person in charge of the other party to start the operation and register;
4. Capacitor discharge: the capacitors must be discharged one by one when working on the capacitor circuit;
5. Remove safety measures: After the overhaul, the operator is scattered, the person in charge of the operation explains clearly to the person on duty, and checks it together, and then the personnel on duty can remove the safety measures and resume power transmission after the visa is completed on both sides of the operation;
6. Hanging of signs: Once the switch is closed, the switch and the operation handle of the knife switch should be hung with the sign of "stop closing, someone is working".
The above articles are the standard treatment methods, we only need to strictly follow the requirements to do, we will be able to ensure personal safety, safe electricity.
