Five related problems of high voltage test equipment.

1. What is the purpose of the high voltage test equipment test?

Due to many factors that affect the electrical performance equipment, only on the theoretical calculation method cannot get, difficult to determine the experience alone, so must carry on the high voltage test equipment, test, analyze and judge various performance according to the test results, to eliminate potential defects, timely detection and treatment equipment aging and the aging problem, determine the reliability of equipment operation.

2. What are the organizational and technical measures to ensure safety?

The work of high voltage test equipment, to ensure the safety of the organization measures are: ① work order system; ② Work permit system; ③ Work guardianship system; (4) Work interruption, transfer and termination system. Technical measures to ensure safety include: (1) power failure; (2) check electrical; (3) earth; (4) suspension.

3. Under what circumstances can high-pressure test equipment be pressurized?

Pressure, high voltage test workers carefully check the wiring, use short route, confirm the instrument ratio, range, apoptosis is zero and the initial state are correct, confirmed, require that all personnel away from being test equipment, and pressure and high pressure test operation personnel in the process of all the pressure, to keep alert to concentration, the possibility of abnormal phenomenon, Operators should stand on insulation pads.

4. What are the requirements for personnel organization of high-pressure test equipment test work?

(1) There shall be no less than two persons for high-pressure test work;

(2) The person in charge of the test shall be an experienced person. Before the start of the test, the person in charge of the test shall arrange the safety precautions for all the test subjects in detail, and explain the live parts of adjacent intervals and other safety precautions.

5. What are the requirements for high voltage test equipment in high voltage test?

(1) The metal shell of the test device shall be reliably grounded. Please shorten the high voltage wire as far as possible and support the high voltage test wire firmly with insulation as needed. Maintain a safe distance from adjacent devices.

(2) The power switch of the test device shall use an obviously open bipolar cutter switch. To prevent the blade from misclosing, an insulation cover can be installed on the blade.

(3) The low voltage circuit of the test device needs two series power switches, and the overload automatic trip device is installed.
