Product Description

 

 

Kdzk-a vacuum degree tester is a vacuum degree identification equipment of vacuum arc extinguishing chamber.
It takes magnetron discharge as the principle and single chip computer as the main control unit. The test process is fully automated. 

The sampling design of the instrument changes the previous method of using current peak value as calibration, and uses ion charge as calibration. In this way, the interference of transient power supply in the test process is effectively suppressed, and the test is stable and reliable. Because the computer is used as the main control unit, kdzk-a vacuum tester can easily deduct the leakage current caused by environmental factors. 

The most outstanding feature of this instrument is that it realizes the disassembly free measurement of the vacuum interrupter, directly displays the vacuum degree value, enables the vacuum circuit breaker users to master the vacuum state of the interrupter in detail, provides a reliable basis for the planned replacement of the interrupter, provides a strong guarantee for the safe operation of the power grid, and overcomes the defect that the power frequency withstand voltage method can only judge whether the interrupter is scrapped. 

With the rise of oil-free medium voltage switch, vacuum switch has been widely promoted and applied for its unique advantages. In recent years, due to the production process and on-site use environment, some vacuum switches may have different degrees of leakage in their vacuum interrupters during operation, and some may leak to the point that they cannot be disconnected normally within the normal service life. In this case, the normal disconnection will occur and cause serious consequences. Domestic vacuum switch accidents are mostly caused by this reason. Therefore, it is very important to strengthen the regular or irregular detection of vacuum degree of vacuum switch. 

Kdzk-a vacuum degree tester has high measurement accuracy, simple operation, convenient carrying and strong anti-interference ability. 
It is suitable for on-site testing of power supply units.It is the necessary and best instrument for the production, installation, commissioning and maintenance of vacuum circuit breakers The traditional detection method is "withstand voltage method", that is, when the vacuum switch is in the off state, a certain voltage is applied between the dynamic and static contacts to detect the leakage current, so as to infer the quality of the vacuum tube. When the vacuum degrades to 10-2 ~ 10-1 PA, although the breakdown voltage does not decrease, the arc extinguishing chamber is unqualified.
