The main function of the isolating switch is:

1. After the opening, it is possible to establish a new and reliable insulation gap. Concisely, it is possible to separate the equipment and lines that need to be repaired from the power supply, that is, to disconnect and separate, so that Electricians can protect their lives and equipment safety.

2, according to the needs of the later operation, and then the operation of the switch line, to bring a lot of help to the later power.

3. It can be used to combine some small currents of the line, such as the charging current of the connector, the bushing, the busbar, the short cable, the excitation current of the voltage transformer and the circulating current when the capacitor current of the capacitor is switched.

4. The isolating switch can be used to combine and divide the no-load excitation current of a certain capacity according to different structural uses. The isolation switch is of course also divided into different isolation modes according to different installation methods, and then can be divided into indoor isolation switches. For outdoor isolation, the outdoor high-voltage isolating switch can withstand natural pressure, such as condensation, ice and thick frost, wind, rain, snow, etc. This type of isolation can be installed at the beginning of the balcony, terrace and other places. The security is quite high.

5. In addition, according to the structure of the insulating pillar, it can also be divided into a double-column isolating switch, a single-column isolating switch, and a three-column isolating switch. The single-column isolating switch has a vertical space directly under the overhead busbar due to the isolating switch. It is used as the electrical insulation of the fracture, so it has obvious advantages compared with the other two. In addition, this kind of opening has the advantages of saving area and reducing the lead wire. In general, when choosing any one, you must choose according to the actual needs, so that you can use it without waste.
