Embodiment Construction

[0019] The exemplary embodiments of the present invention will now be described in detail, examples of which are shown in the drawings, and the same reference numerals refer to the same elements in all the drawings. The embodiments are described below to explain the present invention by referring to the figures.

[0020] The traditional electronic leakage circuit breakers commonly used at present include insulating shells, mechanical components, moving contacts, static contacts, leakage releases, and test devices. The movable contact is connected with the mechanical assembly through the movable contact bracket. The leakage release includes a magnetic leakage protection component, a magnetic leakage protection component striker, and a leakage control printed circuit board (not shown). The test device includes a test button, a test torsion spring, a neutral iron sheet, a test resistor, and a wire for connection. When the electronic leakage circuit breaker is in the closed state, ...

Abstract

The invention relates to a test device used for a miniature electronic type leakage circuit breaker and the miniature electronic type leakage circuit breaker with the test device. The test device comprises a test button, a test torsion spring, a connecting conductor, a lever and a test resistor. The device can make coordination action with mechanical components of the circuit breaker. Whatever the state of the test button is, a test loop is cut off after the transmission of a leakage test signal is completed, so that the circuit breaker can be subjected to periodic tests safely even in reverse wiring.

Description

Technical field [0001] The present invention relates to a miniature circuit breaker, in particular, to a test device for a miniature electronic leakage circuit breaker and a miniature electronic leakage circuit breaker with the test device. Background technique [0002] With the development of electrical automation, miniature electronic leakage circuit breakers have become an electrical appliance widely used in low-voltage terminal power distribution systems. The function of the leakage circuit breaker is to carry out leakage protection and overload protection for the power frequency power supply. When there is a power failure such as an electric shock or the leakage current of the circuit exceeds the specified value, the leakage circuit breaker can produce protective actions such as tripping in a very short time, automatically cut off the power supply, ensure personal safety, and prevent equipment accidents caused by leakage current. The leakage circuit breaker has overload and...
