Abstract

The invention discloses a convenient-to-install high-voltage circuit breaker and relates to the technical field of high-voltage circuit breakers. The circuit breaker comprises a bottom plate; a substrate is detachably fixed on the bottom plate; a circuit breaker body arranged on the substrate; the left side and the right side of the circuit breaker body are respectively provided with side plates,namely a left side plate and a right side plate; the two ends of the inner side of the left side plate are provided with third clamping grooves respectively; third clamping troughs symmetrical to thethird clamping grooves of the left side plate are formed in the two ends of the inner side of the right side plate; fixing cylinders are connected to inner cavities of the third clamping troughs in aclamped mode; a handrail is arranged between the fixing cylinders at the ends, in the same direction, of the two side plates; two parallel side plates form a quadrangle through two handrails; the outer side of each side plate is provided with a reinforcing plate connected with the side plate; the outer side of each reinforcing plate is provided with a pushing and clamping device; the pushing and clamping devices are connected with the reinforcing plates through supporting columns; and the two supporting columns are pushed through the two pushing and clamping devices to enable the two reinforcing plates to clamp the circuit breaker body.

Description

technical field [0001] The invention relates to the technical field of high-voltage circuit breakers, in particular to an easy-to-install high-voltage circuit breaker. Background technique [0002] A high-voltage circuit breaker (or high-voltage switch) can not only cut off or close the no-load current and load current in the high-voltage circuit, but also cut off the overload current and short-circuit current through the function of the relay protection device when the system fails. Perfect arc extinguishing structure and sufficient breaking capacity can be divided into: oil circuit breaker (more oil circuit breaker, less oil circuit breaker), sulfur hexafluoride circuit breaker (SF6 circuit breaker), vacuum circuit breaker, compressed air circuit breaker Devices, etc., and the high-voltage circuit breaker plays a controlling role in the high-voltage circuit, and is one of the important electrical components in the high-voltage circuit. [0003] Most of the existing high-v...
