Embodiment Construction
[0029] Preferred embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will understand the features and advantages of the present invention from the accompanying drawings and corresponding descriptions.
[0030] figure 1 It shows that the circuit breaker with the function of indicating leakage according to the preferred embodiment of the present invention is in the closed state, wherein the circuit breaker includes an indicating mechanism 1 and a double-trip ejector mechanism 7; the indicating mechanism 1 includes a leakage indicator 2, which Leakage mark 2-1 is set on it. In the closed state, since the locking lever 3 of the indicating mechanism 1 is in contact with the leakage indicator 2, the leakage indicator 2 and the handle of the circuit breaker are in the closed position, and the leakage mark 2-1 will not be displayed come out.
[0031] When a leakage fault occurs, such ...

Provided is a circuit breaker with an electric leakage indication function. The circuit breaker is characterized in that the circuit breaker comprises an indication mechanism and a double-release ejecting rod mechanism, the indication mechanism comprises an electric leakage indication member, and the electric leakage indication member is provided with an electric leakage mark. When an electric leakage fault occurs, under the effect of the electromagnetic force, an electric leakage release ejecting rod included by the double-release ejecting rod mechanism is ejected so that the locking of the electric leakage indication member is released; and the electric leakage indication member and a circuit breaker handle rotate together under the effect of an electric leakage indication member spring matched with the electric leakage indication member so that the electric leakage indication mark on the electric leakage indication member is displayed to indicate the occurrence of the electric leakage fault, and the circuit breaker is in a disconnected state at the moment.
Description
technical field [0001] The invention relates to a circuit breaker, in particular, the invention relates to a circuit breaker with the function of indicating leakage. Background technique [0002] In the prior art, circuit breaker products with leakage protection function usually only have one fault indication function, that is, it will indicate regardless of the occurrence of various faults (short circuit, overload, leakage), which makes it impossible for customers to quickly understand the specific cause of the fault , which may prolong the troubleshooting time. [0003] Therefore, there is a particular need in the art for a circuit breaker capable of indicating the type of fault. Contents of the invention [0004] In order to solve the defects in the prior art, the present invention provides a circuit breaker with leakage protection function. The present invention distinguishes different types of faults by setting their own exclusive tripping pins for different faults,...
