TKZKD vacuum switch vacuum tester is also called switch vacuum tester, vacuum circuit breaker vacuum tester and vacuum switch vacuum tester. The vacuum switch vacuum tester is suitable for
A special tester for vacuum switch vacuum measurement and vacuum switch preventive detection. The vacuum switch vacuum tester can easily deduct the leakage current due to environmental factors.
With the rise of the oil-free wave of medium voltage switches, vacuum switches have been widely promoted and applied with their unique advantages. Due to the production process and on-site use environment, some vacuum
The vacuum interrupter of the switch will leak to varying degrees during operation, and some may leak to the point where it cannot be opened normally within the normal life span. In this case, it will be out of
The phenomenon that it cannot be disconnected normally has caused serious consequences. Most domestic vacuum switch accidents are caused by this reason. Therefore, it is very important to strengthen the regular or irregular inspection of the vacuum degree of the vacuum switch.
Link.
The traditional detection method is the "withstand voltage method", that is, when the vacuum switch is in the open state, a certain voltage is applied between the moving and static contacts to detect the leakage current, and then the vacuum tube is inferred.
Good or bad. The advantages of this method are: simple operation; disadvantages: it can only qualitatively detect the quality of the vacuum tube; and the vacuum degree cannot be accurately distinguished between 10-4～10-1Pa, so it is impossible to judge the leakage.
The development trend of leakage (that is, how much leakage does the same vacuum switch have compared to the last time).
TKZKD vacuum switch vacuum tester is an electric power tester developed and upgraded by DL/T846.9-2004 electric power test standard regulations. This vacuum switch vacuum tester replaces the traditional test
Method, the vacuum switch vacuum tester adopts the principle of magnetron discharge, with a single-chip microcomputer as the main control unit, and the test process is fully automated. The vacuum switch vacuum tester can easily
Excluding the leakage current caused by environmental factors, the vacuum degree of the TKZKD vacuum switch vacuum tester can be accurately measured between the vacuum switches, and the vacuum switch does not need to be removed for on-site testing. The tester is equipped with RS232 communication interface.
The TKZKD vacuum switch vacuum tester vacuum switch has been widely used due to its unique advantages. It can be connected to a computer to realize vacuum-ion current curve download, life estimation and other functions.
