Isolation switch configuration 1, both sides of the circuit breaker isolation switch should be configured so as to form a clear fracture and power isolation in the circuit breaker maintenance. 2, neutral grounding transformer Jilin ordinary isolating switch shall be grounded by isolating switch. 3, on the bus arresters and voltage transformers, isolation switch should be combined with a group, to ensure the safety of electrical maintenance and bus Harbin disconnectors, each should be installed on the bus grounding switch set 1-2. 4, connected to the transformer neutral point lead or arrester installed without disconnecting switch. 5, when the side of the feeder line of the user is no power, leading to the user that the circuit breaker can not be installed side isolation switch. However, in order to prevent the lightning over-voltage isolation switch, you can install. Isolation switch conductive loop heat insulator flashover and Qinhuangdao disconnectors, seriously affecting the safe operation of the equipment. You can replace the static compression spring finger stainless steel spring, stainless steel or galvanized high strength bolts and bolts with a torque wrench to tighten; adjust the contact insertion depth and clean the contact surface, Siemens or similar self-cleaning contacts. While using infrared temperature measurement technology on a regular basis to detect heat conductive parts of the case, identify problems in time.
