Problems solved by technology
However, most of the switchgears of the trippers of the circuit breakers in the prior art have complex structures and large volumes, thus occupying more internal space of the circuit breaker, thus making the miniaturization of the circuit breaker and its trippers difficult. Difficulty, or it is difficult to install such a structured switchgear for dielectric testing in a miniaturized circuit breaker or trip unit

The invention provides a tripper and a circuit breaker with the tripper, wherein the tripper has a dielectric test button, a circuit board and an electrode sheet, wherein the tripper also includes: a conductive part, the conductive part A first end is mechanically and electrically connected to the circuit board; an actuator extends through the circuit board, and a first end of the actuator on one side of the circuit board is connected to the dielectric test The button is connected or integrated, and the second end of the actuator on the other side of the circuit board is located near the second end of the conductive member or is electrically connected to the second end of the conductive member; and the power taking member, the The power-taking part is located near the second end of the conductive part, and the power-taking part is electrically connected to the electrode sheet of the release device or is a part of the electrode sheet. The release of the present invention has a simple structure and occupies less space, which is beneficial to the miniaturization of the release and the circuit breaker having the release.
Description
technical field [0001] The present invention relates to trip units and circuit breakers having trip units, and more particularly, to trip units and circuit breakers having dielectric test buttons. Background technique [0002] Circuit breakers are common components in the electrical field, used to make and break electric currents, and to protect lines and equipment in the event of overcurrent or short circuit. Many circuit breakers have a trip unit that releases the holding mechanism and automatically opens the circuit breaker. [0003] When performing a dielectric test on a circuit breaker, a high voltage is usually applied to the electrode pieces of the trip unit of the circuit breaker to test the breakdown voltage between the electrodes (due to the tripping of the electrode pieces of the main part of the circuit breaker and the circuit breaker The electrode pieces of the circuit breaker are electrically connected, therefore, a high voltage can also be applied to the elec...
