The KDZK-A vacuum degree tester is an equipment for evaluating the vacuum degree of a vacuum arc extinguishing chamber. It is based on the principle of magnetron discharge and uses a single-chip computer as the main control unit to achieve automation in the testing process. The sampling design of this instrument has changed from the previous method of using peak current for calibration to using ion charge for calibration. In this way, the interference of transient power supply during the testing process is effectively suppressed, making the testing stable and reliable.
The KDZK-A vacuum degree tester is a device for identifying the vacuum degree of a vacuum arc extinguishing chamber.
The KDZK-A vacuum degree tester has high measurement accuracy, simple operation, easy portability, strong anti-interference ability, and is suitable for on-site testing by power supply units. It is a standing instrument for the production, installation, commissioning, and maintenance of vacuum circuit breakers.
