Device of leakage breaker for combining leakage testing with leakage reset button

Abstract

The invention discloses a device of a leakage breaker for combining leakage testing with a leakage reset button; the part of a testing reset button higher than a frame body is divided into an upper layer and a lower layer; the upper layer is a T-layer face part; the lower layer is a R-layer face part; the lower part of the testing reset button is bent; the bottom part of the testing reset button is convex so as to form a clamping part; the clamping part is clamped with a leakage latch edge bump clasping part in a linking manner; a testing circuit for simulating leakage comprises a double-breakpoint-disconnection protecting function; the device disclosed by The invention has advantages that a testing button is combined with a reset indication button; the device disclosed by The invention is characterized by simple structure and small volume and can be used for leakage breakers with small volumes; and a breakpoint protecting circuit board of a handle convex part has errors on inlet / outlet connection lines so as to avoid being burned.

Description

technical field [0001] The invention relates to a leakage test and leakage reset device of a leakage circuit breaker, in particular to a device integrating a leakage test and a leakage reset button of a leakage circuit breaker with double breakpoint protection functions. Background technique [0002] Most of the existing earth leakage circuit breakers only have a test button. For larger earth leakage circuit breakers, such as Schneider C65Vigi63A and Chint DZ47le products, the test button and reset indicator button of these products are independently separated, and the structure is complex and the shape is large. It is used in small leakage products. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device in which the leakage test of the leakage circuit breaker and the leakage reset button are integrated. [0004] In order to solve the above technical problems, the present invention provides a device in which t...
