technical field

The invention relates to the field of power grid operation and maintenance tools, in particular to a remote control device for spraying conductive liquid.

Background technique

Isolation switch (commonly known as "knife switch"), generally refers to a high-voltage isolation switch, that is, an isolation switch with a rated voltage of 1kV and above, usually referred to as an isolation switch, which is the most used electrical appliance in high-voltage switching appliances. Its working principle and structure are relatively simple, but due to the large amount of use and high requirements for work reliability, it has a great impact on the design, establishment and safe operation of substations and power plants. The isolating switch is used for all levels of voltage, used to change the circuit connection or isolate the line or equipment from the power supply. During the operation of the isolating switch, the contact surface between the contact and the contact finger of the isolating switch is often heated due to the long running time and poor contact of the contact surface of the contact of the isolating switch. The critical defect may cause problems such as burning of the isolating switch. Therefore, the method of power outage is generally used to deal with its faults, but there are many problems as follows:

1. According to the regulations, the critical defect needs to be immediately shut down and then heat treated. However, in actual work, there are problems such as the power supply requirements of important loads and the risk of power outages. The power outage is difficult and the risk of power outages is high. If it is in the process of hot repair, the power supply line trips and causes load loss, which may eventually cause a power grid accident, which will directly affect the image of the power company and the benefits of the company.

2. At present, to deal with the heating of the contact surface of the contact finger of the isolating switch, especially the heat-critical defect, the main method is to grind the contact finger of the isolating switch when the power is cut off. Disadvantages: Power failure of the disconnector will reduce the reliability of power supply, increase the risk of the power grid, and cause grid accidents in severe cases; the disconnector on the line side needs to power down the line, which may cause power outages for important loads, increasing economic losses and social disadvantages.
