Abstract

The invention belongs to the technical field of power equipment, and particularly relates to a low-voltage vacuum circuit breaker based on the Internet of Things, which comprises a flat cable shell, awiring terminal and a vacuum valve, the flat cable shell is made of an insulating plastic material; the wiring terminals are fixedly connected to the upper end and the lower end of the flat cable shell and used for being communicated with wires in a circuit. A first groove is formed in the flat cable shell; the first groove is formed in an opening in one side of the flat cable shell; the openingof the first groove is fixedly connected with a sealing plate through a fastening bolt; the bottom of the first groove is fixedly connected with supporting seats which are uniformly distributed; the supporting base is designed to be in an H shape. The vacuum valve is mounted on the upper surface of the supporting seat; and the lower surface of the supporting seat is fixedly connected with a lowerwiring seat. According to the vacuum circuit breaker, the vacuum arc-extinguishing chamber shell and the vacuum valve are in double sleeve connection, and the vacuum valve is filled with the high-voltage insulating gas, so that the insulating property between the vacuum circuit breaker and the outside can be effectively enhanced, and the safety of the device is further enhanced.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, in particular to a low-voltage vacuum circuit breaker based on the Internet of Things. Background technique [0002] The arc extinguishing chamber of the existing vacuum circuit breaker is generally slidingly connected with a moving conductive rod at the lower end. The static contact at the lower end of the static conductive rod on the upper part of the arc chamber is closed or separated, so as to realize the closing and opening of the circuit breaker; in order to ensure the vacuum degree in the arc extinguishing chamber, there is also a connection between the moving conductive rod and the lower end of the arc extinguishing chamber Metal bellows, the bellows shrink when the movable conductive rod is opened downward, and the bellows stretch when the movable conductive rod is upwardly closed. , directly affects the arc extinguishing effect, and at the same time, due to the influen...
