Abstract

The invention provides an insulating fixture and a method for replacing a tripping electromagnet. The insulating fixture is used for the replacement of a tripping electromagnet of a circuit breaker, and includes an operating handle, a positioning groove and a working groove, wherein the operating handle is located at the first end of the insulating fixture, the positioning groove is located at the second end of the insulating fixture, and is arranged relative to the operating handle; the working groove is located on one side of the second end of the insulating fixture . The insulating clamp has a simple structure and is convenient to manufacture. The use of the insulating clamp to replace the tripping electromagnet of the circuit breaker can effectively avoid the tripping and tripping caused by the action of the opening and tripping rod during the replacement process, and it can be done without power failure. The replacement of the tripping electromagnet is completed, which effectively ensures the safety and continuous power supply of the power supply system, which is conducive to the smooth progress of industrial production and life.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance, in particular to an insulating clamp and a method for replacing a tripping electromagnet. Background technique [0002] The universal circuit breaker is used in the 0.4kv low-voltage power supply and distribution system to distribute, cut off or close the current and charge in the power supply line, and is used in series with the power supply line. The tripping electromagnet is the basic executive element of the electronic release of the universal circuit breaker. It is used to execute the tripping quality issued by the electronic release. As a part of the tripping mechanism, it is connected to the output control terminal XM1 of the electronic release. When the line is faulty, the output end of the electronic trip unit controls the tripping electromagnet, and according to the internal logic judgment, quickly pushes the opening mechanism lever to act to ensure that the connectio...
