Embodiment Construction

[0031] Please refer to the accompanying drawings for a further description of the present invention.

[0032] The invention provides a device in which the leakage test of a leakage circuit breaker is integrated with a leakage reset button. The leakage circuit breaker includes a frame, a test circuit for leakage simulation, an operating handle 3, a test reset button 1, a test reset spring 2, Leakage lock 4, leakage lock spring 6, shaft 8, test conductive spring 9 and brass tube, the part of the test reset button 1 higher than the frame body is divided into upper and lower layers, and the upper layer is a T layer part 101, which is used for leakage test and Leakage reset operation; the lower layer is the R layer part 102, which has an indication of the leakage state; the lower part of the test reset button 1 is bent, and protrudes into an engaging part 104 at the bottom, and the engaging part 104 is engaged with the leakage locking convex buckle part 401 Linkage; the test circui...

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...
