Outdoor vacuum circuit breaker convenient to install

Abstract

The invention provides a convenient-to-install outdoor vacuum circuit breaker, which comprises a circuit breaker main body, clamping pins are arranged at the bottom of the circuit breaker main body, the circuit breaker main body is in buckled connection with fixing buckles on an installation frame through the clamping pins, each fixing buckle comprises a guide groove, a buckle, a transmission part, an adjusting bolt, a pressing block and a pressure spring, and the installation frame is provided with the guide groove. A pressing block is movably arranged at the bottom of the guide groove and can slide up and down along the guide groove, an adjusting bolt is connected to the bottom of the pressing block, the bottom of the adjusting bolt extends out of the mounting frame structure, a transmission part is fixed to the adjusting bolt in a threaded mode, and the tail end of the transmission part is in transmission connection with buckles arranged on the two sides of the guide groove; after clamping pins of the circuit breaker main body are inserted into a mounting frame, the clamping pins press down pressing blocks in fixing buckles to drive the buckles on the two sides to extend out tofix the clamping pins at the bottom of the circuit breaker, mounting is easy and convenient, the structure is stable, corrosion resistance is good, the service life is long, and good development prospects are achieved.

Description

technical field [0001] The invention relates to the field of vacuum circuit breakers, in particular to an outdoor vacuum circuit breaker that is easy to install. Background technique [0002] A circuit breaker is 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 are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy and start asynchronous motors infrequently. It can automatically cut off the circuit when serious overload, short circuit and undervoltage faults occur. Its function is equivalent to the combination of fuse switch and overheating and underheating relay. ...

AI Technical Summary

Problems solved by technology

[0003] However, at present, the vacuum circuit breaker is mainly installed on the utility pole through multiple screws and brackets. Due to the large mass of the circuit breaker, it is inconvenient to install, and the screws and brackets have been exposed to wind and rain for many years. The stability of the distribution box is affected, and there is a great potential safety hazard
