Embodiment 1

[0020] A tripping device for earth leakage circuit breakers, such as figure 1 , figure 2 and Figure 5 As shown, it includes a driving device arranged in the housing 1, and the driving device drives the tripping rod 4 of the circuit breaker body 3 through the linkage member 2 to perform a tripping action; the driving device is an electromagnet device 5, The electromagnet device 5 has a moving iron core 51 that moves linearly. The linkage member 2 includes a first linkage lever 21, a second linkage lever 22 and a pivot member 23. The first linkage lever 21 is linearly movable. On the housing 1, one end of the first linkage rod 21 is directly or indirectly connected to the moving iron core 51, and the direct connection method is such as the contact connection between the outer end of the moving iron core 51 and the first linkage rod 21. , the indirect connection method such as the moving iron core 51 is connected to the first linkage rod 21 through a transition part, the othe...

Embodiment 2

[0024] A leakage circuit breaker, such as Figure 4 As shown, it includes a circuit breaker body 3 and an intelligent control module 10 disposed on the side of the circuit breaker body 3 , and the intelligent control module 10 includes the tripping device described in Embodiment 1. The circuit breaker body is tripped and opened through the tripping device. In practical applications, the intelligent control module 10 also includes a closing device for controlling the closing of the circuit breaker body. The closing device adopts a closing device in the prior art. The gate device is sufficient.

Abstract

The invention provides a trip device for a residual current circuit breaker and a residual current circuit breaker. The trip device comprises a drive device which is an electromagnet device; the electromagnet device has a movable iron core; a linkage component comprises a first linkage rod, a second linkage rod and a pivot member; the first linkage rod can be arranged on a shell linearly movably;one end of the first linkage rod is connected with the movable iron core directly or indirectly and the other end of the first linkage rod is movably connected with one end of the second linkage rod;the other end of the second linkage rod is movably connected with the pivot member; the middle portion of the second linkage rod is rotatably installed on the shell via a first pivot installing shaft;the pivot member is rotatably installed on the shell via a second pivot installing shaft; the pivot member is provided with a trigger rod part and a spring hitching part; the shell is provided with aspring hook; two ends of a resetting spring are connected with the spring hitching part and the spring hook. The trip device is reasonable in structure, fast in trip and high in breaking capacity andachieves a good using effect.

Description

technical field [0001] The invention relates to a tripping device for a leakage circuit breaker and the leakage circuit breaker, belonging to the field of circuit breaker structure design. Background technique [0002] According to the needs of my country's power supply network intelligence, the State Grid Corporation of China requires the power supply network intelligence. Therefore, it is necessary for the terminal actuator of the power supply network - the circuit breaker to perform the upper-end signal to have the functions of tripping and closing. The current development trend of the circuit breaker is that in addition to the traditional manual opening and closing and over-current and overload automatic tripping functions, it also has the automatic opening and closing function to realize remote control. [0003] In the prior art, there is a tripping device for an earth leakage circuit breaker, its structure includes a trigger for triggering the tripping of the circuit ...
