Problems solved by technology

However, the existing circuit breaker structure makes it very inconvenient to replace the controller, and the operation is very cumbersome. First, it is necessary to disassemble the circuit breaker casing, and then disassemble the control box, and then replace the circuit board in the controller. Great inconvenience to the entire power supply system

Abstract

The invention discloses a breaker, comprising a housing and a controller casing, wherein the housing comprises a pedestal and a face shield, the controller casing is arranged in the housing, the face shield comprises an observation window and a sealing cover, the observation window is arranged on the face shield, the size of the observation window is larger than that of the controller casing; the sealing cover is movably connected with the observation window, the sealing cover comprises a sealing cover frame and a transparent plate, an inner frame surface of the sealing cover frame is provided with a plurality of clamping grooves, clamping members mating with the clamping grooves are correspondingly arranged on the transparent plate, the transparent plate is arranged on the sealing cover frame via the clamping members and the clamping grooves, and the sealing cover frame is arranged on the observation window via a connecting member. The breaker is simple in structure, convenient in dismounting, and can effectively simplify steps in dismounting the controller.

Description

technical field [0001] The invention relates to a circuit breaker. Background technique [0002] The universal circuit breaker is suitable for the power distribution network with AC 50Hz, rated voltage 380V, 660V, and rated current 200A-6300A. It is mainly used to distribute electric energy and protect lines and power supply equipment from overload, undervoltage, short circuit, single-phase grounding and other faults. The circuit breaker has a variety of intelligent protection functions, which can achieve selective protection, precise action, avoid unnecessary power outages, and improve power supply reliability. [0003] During the use of the universal circuit breaker, because the circuit board in the controller is relatively easy to age, the service life is relatively short. In order to ensure the safety of use, some competent departments will stipulate that the controller of the universal circuit breaker must be replaced after a certain number of years of use. However, t...
