Electric leakage detection device for marine moulded case circuit breaker

Abstract

The invention discloses an electric leakage detection device for a marine moulded case circuit breaker. The electric leakage detection device comprises the moulded case circuit breaker and an electricleakage detection device body; a connecting seat is fixedly mounted between the moulded case circuit breaker and the electric leakage detecting device body; one side of the electric leakage detectiondevice body is fixedly provided with a wiring terminal; the top of the electric leakage detection device is fixedly provided with an anti-radiation cover; one side in the electric leakage detection device body is fixedly provided with an electric leakage sensor; the other side in the electric leakage detection device body is movably provided with a rotary shaft through a bearing; a driven gear ismovably mounted at the position, close to the lower portion, of the exterior of the rotary shaft; and fan blades are fixedly mounted at the position, close to the upper position, of the exterior of the rotary shaft. According to the electric leakage detection device for the marine moulded case circuit breaker, active heat dissipation can be carried out, so that the heat dissipation effect is improved; and the anti-interference capability can be achieved, so that a complex environment is prevented from affecting the detection effect.

Description

technical field [0001] The invention relates to the field of detection devices, in particular to a leakage detection device for a marine plastic case circuit breaker. Background technique [0002] Marine molded case circuit breaker leakage detection device is a leakage detection device used for molded case circuit breakers. It is mainly used to detect whether there is leakage in the molded case circuit breaker. The circuit breaker is used to isolate the conductors and the grounding metal part. It can automatically cut off the current after the current exceeds the trip setting. Therefore, the molded case circuit breaker is a hub between electric power, so it has certain safety hazards, so it needs However, the existing leakage detection devices for marine molded case circuit breakers do not have the heat dissipation function, because both the molded case circuit breaker and the leakage detection device will generate heat when they are in use, and the molded case circuit break...
