Problems solved by technology

[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. Used in small leakage products

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

An integrative device of a leak test and leak reset button for a leak breaker. The part of the test reset button above a case body is divided into two layers. The upper layer is a T layer surface (101) and the lower layer is a R layer surface (102). The test reset button bends in the underside and stands out to form a combine part (104) in the bottom. The combine part is clipped with a chimb combine part (401) of a leak lock to form a linkage. A test circuit simulating the leak current is provided with the protect function of double break nods to turn off. The advantages of the invent is to integrate the test button and reset button into a single device, therefore the structure gets simple and small and can be used in a smaller leak break. A burn accident is avoided by a break nod circuit board in the projection part of a handle when inlet and outlet wires in errors.

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...
