How to determine the isolation switch contacts is overheating? A: According to the isolation switch or change the paint color of the test piece the contact portion of warm color to determine Linyi isolation switch can also be determined based on the color of hair or dark blade. Now generally based on the results of infrared temperature measurement to determine. How malfunctioning electrical isolation switch should check processing? A: After the failure of Jining isolating switch disconnectors electric operation, first check whether the operation error, and then check the operation of the power circuit, power supply circuit is intact, the fuse is blown or loose. Electrical lockout circuit is normal. Isolating switch contact welding deformation, damaged insulators, severe discharge should I do? Disconnectors A: In these cases should be treated immediately power, should be strengthened before the power failure monitoring.
