Standard for normal maintenance of high voltage switchgear
2016-08-04
In the process of debugging and running, the high voltage switchgear will be in trouble, and the maintenance of the following items should be carried out in order to reduce the frequency of failure:
1 overhaul procedure lock and interlock, the operation is flexible and reliable, and the program is correct.
2 according to circuit breaker, isolating switch, operating mechanism and other electrical appliances for the maintenance of the provisions of.
3 check the electrical contact parts, see if the condition is good, to detect the grounding circuit.
4 hand car must check the situation of the vehicle propulsion mechanism to ensure that it meets the requirements of the specification.
5 check the two auxiliary circuit is abnormal, the two auxiliary circuit terminal is loose, and the necessary maintenance.
6 check all parts of the fasteners, such as loose should be tightened immediately.
7 check ground parts of the loop, such as grounding contact, main grounding wire and grounding wire door, guarantee the continuity of the conductive.
Check the gas pressure of 8 SF6 load switch indicator data, depending on the situation in a timely manner qi.
9 clean all parts of the dust, especially the dust on the surface of the insulating material.
10 daily run time to pay attention to whether there is a big load when the abnormal sound, to facilitate the shutdown of the reinforcement.
Cleaning and strengthening of terminal of relay protection device 11.
