Circuit Breaker Switch Test Instrument

Disconnector is the most widely used high voltage switchgear in power system. The operation condition of disconnector is very bad, which is easy to cause mechanical or electrical failure. In particular, the contact part of the touch finger is vulnerable to rain, dust and harmful gases, resulting in poor contact and heating. The spring that provides the pressure of the touch finger will be annealed due to heating, which will reduce the pressure. This will lead to a vicious circle of the touch finger heating, and eventually burn the touch finger and cause an accident.
In view of the current maintenance status of the power generation and supply system, our company has developed an intelligent tester for measuring the contact pressure of the high-voltage disconnector. As long as the sensor of the analog contact of the test clamp is opened at the contact position of each pair of contacts, the contact pressure of the contacts can be displayed and remembered. The HV disconnect testing device effectively solves a difficult problem of measuring finger pressure.

The common method to judge whether the vacuum degree of vacuum tube is deteriorated or not is power frequency withstand voltage method. This method can only judge the interrupter with serious vacuum degree deterioration. However, when the vacuum degrades to 10-2～10-1 PA, although the breakdown voltage does not decrease, the interrupter is not qualified.
RDZK-208 vacuum switch vacuum tester adopts excitation coil and magnetic controlled discharge method to test the vacuum degree of arc extinguishing chamber without dismantling the arc extinguishing chamber. At the same time, the microcomputer is used for synchronous control and data acquisition and processing, so that the field test sensitivity of the vacuum degree of the interrupter reaches 10-5Pa. The outstanding feature of vacuum switch vacuum degree tester adopts excitation coil and data processing method to realize the measurement of vacuum degree without disassembly. Vacuum switch vacuum degree tester has the advantages of convenient use, simple operation, no disassembly, high measurement and test accuracy.
Interrupter Vacuity Tester is a practical testing instrument, which is widely used in electric power, steel, petrochemical, textile, coal, railway and other departments using vacuum switch
