Safety tool series pressure resistant device

The NYZ safety tool series pressure resistant device adopts multi-channel high-voltage leakage measurement technology and infrared data communication technology to achieve the purpose of safe measurement of high-voltage leakage current. In order to improve work efficiency, 8 samples can be tested simultaneously at a time. To avoid repeated testing, high-voltage breaking technology is used. During the testing process, the punctured samples can be removed from the high-voltage testing system, and the non punctured samples can continue to be tested until the test is completed.

Performance characteristics of NYZ safety tool series pressure resistant device:

Conduct a test on 8 insulated boots or gloves simultaneously, and measure the leakage current separately.
◆ Adopting a large screen LCD full Chinese character display, it displays a large amount of information, and simultaneously displays parameters such as 8 high-voltage leakage currents, test voltage, current, timing time, etc. on one screen.
◆ It can measure parameters such as test voltage and primary current of the test transformer.
Using infrared communication technology to isolate the control panel from the high-voltage system, ensuring the safety of the testing personnel.
◆ Fully automatic voltage withstand test. After the experiment begins, the instrument automatically closes and boosts the voltage at the required speed according to the national standard. It starts timing and maintaining the test voltage when it reaches the predetermined voltage. When the time is up, it automatically drops to zero and cuts off the power. At the same time, it displays the leakage current of each test sample and automatically saves the test results.
◆ Equipped with a grounded container for easy operation.
Each test sample is equipped with a high-voltage breaking mechanism. When any one of the circuits breaks down, the test sample will automatically detach from the high voltage without affecting the progress of the test.
◆ It has overvoltage and overcurrent protection functions.
◆ Equipped with high-voltage hazard warning light display.
