Electric energy meter external circuit breaker

Abstract

The invention discloses an electric energy meter external circuit breaker comprising a circuit breaker body and an adjusting device. A side wall of the circuit breaker body close to a front side of acontrol switch is fixedly equipped with a fastening device, and an electro-hydraulic push rod is rotatingly connected in a connecting member. A protection cover is rotatingly connected to one side ofthe electro-hydraulic push rod close to the upper side of the circuit breaker body, and the adjusting device is embedded and installed in a sliding chute. Through the combined use of the fastening device, an insertion rod and an anti-slip sleeve, a staff can quickly and effectively fasten an external wire, thereby the installation and disassembly time of the external wire is shortened, through theadjusting device, the staff can install the circuit breaker body according to different installation areas, the stability and safety between the circuit breaker body and a contact object are improved, the top of the circuit breaker body can be effectively protected through the protection cover, and the damage to the circuit breaker body due to an external force is reduced.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an external circuit breaker for electric energy meters. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy. Start the asynchronous motor frequently, protect the power line and the motor, and automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equivalent to the combination of a fuse switch and an overheating relay. , and generally do not need to change parts after breaking the fault current. At present, it has been widely used. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of u...

AI Technical Summary

Problems solved by technology

[0003] A Chinese patent discloses a circuit breaker shell structure and a circuit breaker (authorized announcement number CN206340497U). This patented technology can effectively evacuate congestion in the The arc extinguishing smell in the exhaust channel can be diverted to cool down the arc extinguishing gas and discharge it out of the housing. However, this circuit breaker lacks corresponding protection measures. At the same time, the external wires and the circuit breaker body are usually fastened with bolts, which is time-consuming and laborious. It is convenient for the staff to quickly fasten the external wires, but the installation of the circuit breaker will be affected by the external environment, and it is not convenient for the staff to quickly fix it. Therefore, those skilled in the art provide an external circuit breaker for the electric energy meter. To solve the problems raised in the above-mentioned background technology
