Common failure of high voltage switch cabinet and Its Countermeasures

1, mechanical chain failures: in order to ensure the correct operation of the switch, the switch cabinet set up a number of mechanical. For example, when the switch cabinet handcart import must be off. Switch off cannot operate isolating switch. This kind of breakdown form is various, should carry on the search along the mechanical transmission path. General protection agencies are relatively simple, and other agencies rarely cross, to find more convenient.
2, the operating mechanism of failure: the operating mechanism is the most fault location of the site is limited. For example, in the CT8 mechanism in fan wheel and axle engagement is the key to release adjustment. With large amount of tripping resistance is large, easy to get stuck. The meshing volume is small, easy to jump, not closing. Adjusting the method is to change the length of the limit bolt and the connecting rod.
Although a variety of fault of high voltage cabinet is diverse, but as long as you can switch in the accident trip, electric manual can not judge out of high voltage switch cabinet of common electrical or mechanical failure, determine the fault position according to the fault phenomena and inspection results, can quickly eliminate.
