Helium mass spectrometry leak detection and positive pressure helium detection for power insulation components

Epoxy resin insulation is a widely used insulation material in power equipment, with good insulation performance, high mechanical strength, and fire resistance, which can ensure the safe and stable operation of electrical equipment.

With the continuous updating of power equipment, the requirements for epoxy resin insulation parts are becoming increasingly strict. Traditional negative pressure testing can no longer fully meet customer needs. Based on customer needs, a new “positive pressure method” testing equipment has been launched to address and solve customer pain points, improve customer testing efficiency and detection rate.

Specific method:

1. Place the product on the device and click the start button;

2. Touch and press down on the device, press the product tightly, and vacuum the lower end;

3. When the preset vacuum degree is reached, low-pressure helium gas is automatically sprayed to screen for large leaks. If the large leak screening passes, the helium gas is pressurized to the set pressure and the equipment performs automatic detection;

4. If there is a leak in the product, helium gas will enter the equipment through the internal channel leakage hole. If it exceeds the preset alarm value, the equipment will sound an alarm and automatically stop;

5. When the leak detection reaches the set time and passes the test, the equipment will automatically stop, remove the product, and proceed to the next leak detection operation.
