Improved intelligent circuit breaker

Abstract

The invention discloses an improved intelligent circuit breaker which comprises a circuit breaker casing and an arc extinguishment chamber arranged in the circuit breaker casing. The improved intelligent circuit breaker is characterized in that a vacuum mechanism is further arranged in the circuit breaker casing. The vacuum mechanism comprises a transmission shaft, a vacuum pipe, an insulation clamping plate and a crank handle. The vacuum pipe is arranged at the upper end of the vacuum arc extinguishment chamber, the insulation clamping plate is arranged at the upper end of the vacuum pipe, a through hole is arranged in the middle of the insulation clamping plate, a fixed support frame is installed in the through hole, the fixed support frame is connected with a connection rod through a rotating device, the connection rod is in linkage with a transmission shaft through the crank handle, an intelligent controller is arranged on one side at the upper end of the insulation clamping plate, the transmission shaft is controlled by the intelligent controller, a control device is arranged on the outer portion of the circuit breaker casing, and the intelligent controller is controlled by the control device. The improved intelligent circuit breaker has the advantages of being simple in structure, convenient to operate and use and high in intellectualization degree, improving stability and working efficiency and prolonging service life.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to an improved intelligent circuit breaker. Background technique [0002] In power systems, circuit breakers are widely used as power distribution equipment, among which vacuum circuit breakers are the most used. Vacuum circuit breakers are named for their arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing. , which has the advantages of small size, light weight, and no maintenance for arc extinguishing. It is widely used in distribution networks and is widely accepted and adopted by users due to its unique advantages. However, because the circuit breaker is in frequent work for a long time, There will be mechanical damage caused by work fatigue, damage to the arc extinguishing chamber by external factors, and equipment failure caused by small current in the equipment. Therefore, in order to solve the above problems, a new technical solution is provided....
