The items that need to be tested for SF6 gas mainly include the following aspects:
1. SF6 gas concentration detection: detects the concentration of SF6 gas in the air to determine whether there is a SF6 gas leak.
2. SF6 gas pressure detection: detects the pressure of SF6 gas in certain equipment to ensure normal operation.
3. SF6 gas temperature detection: Detect the temperature of SF6 gas to ensure that the equipment temperature is within a safe range.
4. SF6 gas purity detection: Detect the purity of SF6 gas to ensure compliance with usage standards and reduce environmental pollution.
5. SF6 gas decomposition product detection: detect the decomposition products of SF6 gas, determine whether SF6 gas is operating normally, and detect potential faults.
6. SF6 gas leakage detection: detects SF6 gas leakage to ensure environmental and personnel safety.
