Withstand voltage test indicating device of earth leakage circuit breaker

Abstract

The invention relates to a withstand voltage test indicating device of an earth leakage circuit breaker. The withstand voltage test indicating device comprises an indication surface cover and a shell.The indication surface cover comprises character indication information of a normal operation working position and a withstand voltage test position. A sliding cover is arranged on the upper portionof the shell, an electric leakage closing structure and a traction rod are arranged in the shell, a knob hole is vertically formed in the sliding cover, claw plates are arranged on the two sides of the bottom of the sliding cover, a positioning groove and a positioning groove are formed in the middle of the bottom of the sliding cover, a draw rod connecting part is arranged on one side of the sliding cover, the bottom surface of the draw rod connecting part is provided with a draw rod groove, straight rail surfaces are arranged at two sides on top of the shell, the top of the shell is providedwith a positioning convex point, one side of the sliding cover is provided with a draw bar, and the middle of the draw bar is hinged in a breaker operating mechanism. The device is simple and compactin structure, and achieves a clear and definite indication function of allowing a product to be subjected to a withstand voltage test. According to the invention, a withstand voltage test is carriedout, and misoperation of re-tripping, closing and opening of a product by an operator is prevented.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical appliances, and relates to a withstand voltage test indicating device of a leakage protection circuit breaker. Background technique [0002] Most leakage protection circuit breakers do not have an indicating device that allows the product to undergo a withstand voltage test, which may easily cause the leakage function electronic circuit board to be directly broken down during the withstand voltage test and damage the product; [0003] Although some existing technologies have realized the local indication function, they cannot avoid the risk of the operator operating the leakage protection circuit breaker by mistake during the withstand voltage test. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a leakage protection circuit breaker withstand voltage test indicating device, on the one hand to allo...
