Manufacturers of high-voltage test transformers must abide by the regulations of high-voltage test transformers during the high-voltage test. When performing maintenance and testing on the electrical connection part at the same time, fill in the work ticket. However, the person in charge of maintenance should obtain permission before the test.
After the high-voltage test work ticket is issued for the same electrical connection part, it is forbidden to issue a second work ticket. If there is a sufficient safety distance for the disconnection point between the pressurized part and the inspection part, and there is a short circuit on the other side, the series resonance can be tested on one side of the disconnection point, and the other side can continue work, but at this point the disconnect point should hang with“ Stop, high voltage is dangerous!” Signs and special supervision; 2. The high voltage test should not be less than two people. The person in charge of the test should be an experienced person.
Before the test, the person in charge of the test should arrange the safety precautions of all test personnel in detail during the test; 3. When the equipment connector needs to be disconnected due to the test, it should be marked before disassembly, and then checked; 4. The metal shell of the test device should be Reliable grounding, the high-voltage lead wire should be as short as possible, and if necessary, it should be firmly supported by insulators. The power switch of the test device should be a double-knife switch that is clearly disconnected. There should be two power switches in series in the low-voltage circuit of the device, and an overload automatic tripping device should be installed; test transformer 5. Shields or fences should be installed on the test site and hung outwards“ Stop, high voltage is dangerous!”When the two ends of the equipment under test are not in the same place, someone should be sent to guard the sign; 6. Before pressurizing, the multiplier of the test wiring table must be carefully checked. The regulator is correct at zero and instrument start. Pressurization can only be done after notifying the relevant personnel to leave the equipment under test and obtaining the permission of the person in charge.
Pressurization should be monitored and chanted. High-voltage testers should concentrate and not talk to others. Always be on the lookout for exceptions.
The operator should stand on the insulating pad; 7. When changing the wiring or the end of the test, the test power supply should be disconnected first, discharged and the high-voltage part of the booster equipment should be short-circuited to the ground; Discharge before test. In the high-voltage direct current test, the equipment should be discharged several times to the ground and short-circuited to the ground; 9. At the end of the test, the test personnel should remove the self-installed grounding short-circuit line, and check and clean the equipment under test; 10. Special important electrical For the test, after being approved by the competent production leader (chief engineer), detailed test measures should be taken. The regulations that the high-voltage test transformer must comply with during the high-voltage test High-voltage transformer manufacturer Shenzhen Fulude Electric Power Technology Co., Ltd. The above is the regulation that SHENZHEN NOYAFA ELECTRONIC CO., LIMITED introduced to you when the high-voltage test transformer must comply with the high-voltage test If you are still interested in related content, please continue to pay attention to SHENZHEN NOYAFA ELECTRONIC CO., LIMITED to read more about the working principle of the cable fault tester? .
