Vacuum circuit breaker capable of warning and broadcasting

Abstract

The invention discloses a vacuum circuit breaker capable of warning and broadcasting. The circuit breaker comprises a shell assembly and a circuit breaking assembly, wherein the shell assembly comprises a base, an illuminating lamp, a broadcasting machine, a loudspeaker and a machine shell, the illuminating lamp is arranged at the left position of the top of the base, the illuminating lamp is in threaded connection with the base, the broadcasting machine is arranged at a right end of the base, the broadcasting machine is detachably connected with the base, the machine shell is arranged on an outer side wall of the broadcasting machine, the machine shell and the broadcasting machine are integrally formed, and the loudspeaker is arranged at the left position in the machine shell. Through a warning broadcast component, when a worker detects and maintains a circuit and needs to disconnect a vacuum circuit breaker, a switch of the broadcasting machine is turned on, the loudspeaker gives outwarning sound by connecting the circuit, so other workers can know that the circuit is detected and maintained, the circuit breaker is prevented from being connected again due to unknown conditions,and life safety of a maintainer is ensured.

Description

technical field [0001] The invention belongs to the technical field of electrical machinery, and in particular relates to a vacuum circuit breaker for warning and broadcasting. Background technique [0002] Vacuum circuit breaker is named for its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum. It has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. It is used in distribution network It is widely used in industrial and mining enterprises, power plants and substations for protection and control of electrical equipment. It is especially suitable for places that require no oil, less maintenance and frequent operations. The real circuit breaker can be configured in the middle Cabinets, double-layer cabinets, and fixed cabinets are used to control and protect high-voltage electrical equipment. [0003] During the use of the original vacuum circuit b...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a vacuum circuit breaker for warning and broadcasting, so as to solve the above-mentioned background technology. During the use of the original vacuum circuit breaker, the staff want to detect and maintain the circuit, and disconnect the circuit through the vacuum circuit breaker. , because there is no notification of the warning broadcast, other staff will not know the situation, and the vacuum circuit breaker will be turned on again. Since the line is high voltage, it will cause serious harm to the life safety of the maintenance personnel.
