To do a good job of electrical equipment troubleshooting can not only make the power plant always in safe operation, but also improve the user's satisfaction with the work of the power plant. For the power plant electrical equipment, if there is a fault, it can not provide power for users, and the production and life of users will be paralyzed. And do a good job of troubleshooting, you can find hidden dangers in the electrical equipment in time, and eliminate the hidden dangers, and then provide users with uninterrupted power supply, meet the needs of users, social production will not stop, it can be seen that doing a good job of electrical equipment troubleshooting has special significance.
After the electrical equipment runs for a period of time, it will inevitably be worn or interfered. If it cannot be eliminated in time, it will threaten the safe operation of electrical equipment. But in order to solve the electrical fault, it is necessary to understand the common faults of electrical equipment
(1) Short circuit.
The main reason for short circuit of electrical equipment is that the insulation layer no longer has insulation ability, and the reason for this situation is that the insulation layer is damp or worn. Some of them are that the insulation layer is aging due to the long service time of the line, and the electrical equipment is out of repair for a long time.
(2) The temperature is too high.
For electrical equipment, wires must be needed in operation, but each kind of wire has its own height limit to bear the current load range. If the current load is abnormal and exceeds the original bearing capacity of the wire, the temperature of the wire will be increased instantly, and then the wire will be burned. The reason for this situation may be related to the lack of lubricating oil after long-term operation of the equipment. At the same time, it may also be that the operation space of the equipment is too small to emit heat in time. In addition, the failure to clean the dust and debris for the equipment in time will also lead to high temperature, which will threaten the safety of electrical equipment.
(3) Arc and spark.
In the operation of electrical equipment, it is easy to produce arc and electric spark due to the damage of wire insulation. Once this happens, it will directly threaten the overall safety of the power plant, especially the electric spark is easy to cause electric fire, which is very difficult to deal with.
(4) Harmonics cause faults.
In the operation of electronic equipment, it is inevitable to produce harmonics. These harmonics have a great impact on electronic equipment, and even cause misoperation, which is easy to bring threats to the safe operation of electrical equipment and current operation, which is not conducive to the improvement of power grid quality.
