Inflatable test transformer for safe use
Inflatable high voltage test transformer withstand voltage test operation precautions
Inflatable high-voltage test transformer is one of the best equipments for various pressure test. In order to complete the test more smoothly, what should we pay attention to when using the pneumatic test transformer for various pressure test?
1. The arrangement of the test equipment should have sufficient safety distance around the person. Try to avoid arranging equipment and applying high voltage leads on the personnel aisle.
2. Install the fence at the test site and hang the “stop, high pressure danger†sign.
3, inflatable test transformer test high-voltage lead should have support or traction insulation. Have a safety guard to prevent someone from approaching and passing underneath.
4. In the DC high voltage test, when the micro-ampere table is in the high position, there is an overcurrent automatic protection device in addition to the shielding box to prevent the table from burning out due to sudden breakdown or short circuit.
5, power frequency withstand voltage test: Please pay attention to check whether the equipment capacity is sufficient, and should avoid resonance.
6. The working ground wire (high-voltage tail, voltage-stabilizing capacitor end grounding wire) and protective ground wire (operating box outer casing) should be connected separately and have good grounding performance.
7. If the power supply irregular swing (such as electric welding) in the test will affect the high-voltage output stability, the test should be stopped at this time to find out the cause.
8. The requirements for climate (temperature, humidity) of the inspection work shall comply with the requirements of the test procedures and be recorded.
9. The high-voltage test work must strictly implement the relevant provisions of the safety work procedures issued by the Ministry of Energy.
Electric power personnel must pay attention to the above matters when testing with inflatable test transformers. This not only ensures the completion of the test, but also guarantees our own safety.
