In order to strengthen the management of high and low voltage electrical equipment and ensure the normal operation of all electrical equipment, the following treatment methods are specified for this purpose:
One: high pressure part
1. The purpose of troubleshooting is to limit the development of accidents as soon as possible, and to eliminate the threat to personal and equipment safety and the root cause of accidents.
2. When a substation fails, the on-duty personnel should promptly and correctly report the accident occurrence time, phenomenon, equipment name and number, trip switch, relay protection action and ambient voltage.
3. When a substation fails, the duty officer should first judge the accident according to the meter indication and the external symbol of the equipment. If there is a threat to the person and equipment, he should immediately try to lift it and stop the equipment if necessary. run.
4. In the process of repairing the faulty equipment, the replacement of the damaged equipment must be in strict accordance with the "Specifications", and carefully fill in the work records.
5. When there is a fire in live equipment, dry fire extinguishers, carbon dioxide fire extinguishers, 1211 fire extinguishers should be used. Foam fire extinguishers are strictly prohibited.
Two: low pressure part
1. Purpose: Firstly, the on-duty electrician should be required to seriously study business knowledge, and must have a high degree of responsibility and strengthen inspections.
2. The duty electrician should correctly judge whether the electrical equipment is overloaded or not according to the meter. If it is overloaded, report to the superior in time. When the electrical equipment (transformer) is seriously threatened, it can be used to avoid peaks in unimportant workshops.
3. Low-voltage electrical equipment, such as knife gates, circuit breakers, contactors, etc., are prone to malfunctions due to frequent movements. Therefore, the duty electrician is required to make serious judgments and take timely maintenance measures. When repairing, you must wear insulated shoes, insulated gloves, and cut off the power supply. It is verified that there is no electricity before it can be operated.
4. Common faults of low-voltage lines. According to the actual situation of the company, it is easy to cause overheating of the line. The insulation layer of the wire ages with time, and the insulation layer of the wire is damaged by organic solvent. The above cases can be replaced in time according to production needs, and temporary lines should be set up when necessary, but they must be strictly in accordance with the "low regulations".
5. Low-voltage electrical equipment, common faults of the motor: First, the phase loss operation, and the second is overloaded operation and damage. In order to avoid the above two faults, the motor thermal component protection must be adjusted to the corresponding current value. In short, the on-duty electrician is required to strengthen the inspection tour and be responsible.
6. When a fire occurs in electrical equipment, use the fire extinguisher properly to extinguish the fire as described above.
