The Importance of Vacuum Interrupter Test Sets

The high-voltage vacuum interrupter test set is a specialized instrument used to measure the vacuum degree of high-voltage switches. It can accurately determine the vacuum state of high-voltage switches through advanced sensing technology and precise measurement algorithms, thereby evaluating the operational performance and reliability of the equipment. In the power system, once the vacuum degree of high-voltage switches decreases, it will seriously affect the breaking capacity and insulation performance of equipment, and may even cause serious safety accidents. Therefore, regularly using instruments to detect the vacuum degree of high-voltage switches is one of the key measures to ensure the stable operation of the power system.

Scope of application

This vacuum interrupter test set is widely used in various aspects of the power system, including power generation, transmission, transformation, and distribution. In the power generation process, the tester can be used to detect the vacuum level of high-voltage switchgear such as generator outlet circuit breakers and plant power circuit breakers; In the transmission process, the tester can be used to detect the vacuum level of isolation switches, load switches, and other equipment in the transmission line; In the substation process, the tester is mainly used to detect the vacuum degree of high-voltage switchgear such as circuit breakers and isolating switches in the substation. In addition, in the distribution process, the tester can also be used to detect the vacuum level of equipment such as ring main units and branch boxes in the distribution network.

Core advantages of the Vacuum Interrupter Test Set

Strong anti-interference ability:

The magnetic field suppresses the serious impact of electrode surface conditions (such as cleanliness, roughness, and material) on measurement results, improving the repeatability and accuracy of measurements.

Wide measurement range:

capable of covering a wide range from high vacuum to low vacuum, meeting the detection needs of switches at different stages from good to deteriorated during operation.

Quantitative results:

Directly display the vacuum degree value in pascals (Pa) instead of a simple "qualified/unqualified" indication, which facilitates the establishment of equipment records and trend analysis.

Precautions for Vacuum Interrupter Test Set operation

1. The vacuum interrupter test set casing should be reliably grounded;

2. To improve measurement accuracy, the outer surface of the vacuum switch should be wiped clean before testing;

3. Please choose the correct type of vacuum tube;

4. During the testing process, the high-voltage output terminal will output a high voltage of about 20KV. Please maintain an insulation distance between it and the human body and the low-voltage line terminal (it is recommended to maintain a distance of more than 0.5 meters from the human body). The magnetic field voltage output terminal will output a high voltage of about 1600V. Please pay attention to safety!

5. When conducting experiments on the instrument, the wiring should first be connected to the magnetic coil and vacuum tube, and then connected to the instrument. After the test is completed, the test wires connected to the instrument should be removed first, and then the wires connected to the magnetic coil and vacuum tube should be removed; If you forget to connect the magnetic coil and press the measurement button directly during use, immediately turn off the power and reconnect the magnetic coil. Please note that there will be a high voltage at the output end of the magnetic field voltage. When wiring, do not touch the conductor part to avoid being damaged by residual voltage on the capacitor

6. After the measurement is completed, there may still be residual voltage of about 40V at the magnetic field output terminal. Please pay attention to safety!

FAQ

Q: Is it necessary to dismantle the vacuum switch during on-site measurement?

A: By using a new type of side attached electromagnetic coil or excitation coil to surround the arc extinguishing chamber from the side, on-site measurement without disassembling the vacuum bubble is achieved, avoiding the tedious work of adjusting mechanical parameters during reinstallation.

Q: Does vacuum interrupter test set support customization?

A: Support LOGO customization, multilingual interface, external packaging customization, etc.

Q: How to store instruments when not in use?

A: Store in a dry, dust-free, and non corrosive gas environment. Magnetic field coils are precision components that should be avoided from being dropped or bumped. It is recommended to regularly (e.g. every 3 months) turn on the power for half an hour to prevent the electrolytic capacitor from aging.
