Fracture of porcelain must be comprehensive management disconnectors wholesale, first of all to ensure overall structure is reasonable isolation switch, followed by even strengthen the porcelain manufacturer choice, you can specify an isolation switch production companies use superior quality and good reputation manufacturer of porcelain products. In addition, it can conduct non-destructive testing technology, porcelain regularly tested. Operating personnel to strengthen surveillance, particularly the observation of porcelain glued surface. When you run the operation to be the right way disconnectors prices, such as when operating difficulties should not by force. Isolating switch refused points, closing what should I do? A: (1) Since the shaft pin off, wedge bolt exit, cast iron fracture mechanical failure, or because the electrical circuit failure may occur Arbor touch with the operating mechanism, thereby causing denial closing isolation switch, then use insulated rod operation or puffer type in ensuring the personal safety of the isolation switch, turn the switch to isolate each shaft with a wrench. (2) refuse the trip. When the isolation switch will not pull out when the actuator is the case of frozen ice, shake gently, and observe the partial support of porcelain and institutions in order according to where the deformation and displacement, identify obstacles locations. If the failure location occurs in the contact portion isolating switch should not be forcibly opened, or support insulator may be affected by damage caused by a serious accident, then change the operation mode of the device can only be dealt with.
