Problems solved by technology

At present, there are many parts in the transmission mechanism of the release of similar small circuit breakers at home and abroad, and the transmission form is relatively complicated, and the stability of the transmission effect of multi-point linkage is obviously different, so sometimes it cannot reach the ideal state. Therefore, the entire control circuit It is easy to cause quality problems
[0005] In addition, the performance of some miniature circuit breaker accessories on the market not only fails to provide the protection required by the design, but also affects the performance of the miniature circuit breaker.
In particular, the undervoltage protection modules in the accessory products in the prior art basically use high-power undervoltage releases, which consume a lot of energy.

Embodiment Construction

[0026] Specific embodiments of the tripping device of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] The tripping device of the present invention includes: a tripping device 1 and a transmission mechanism. Wherein, the release 1 includes a coil, an iron core, and a spring that biases the iron core in one axial direction (downward direction in the illustration) of the coil. Since this release is prior art, Therefore, it will not be described in detail here.

[0028] The transmission mechanism in the tripping device of the present invention (not shown in the figure, all the components whose first numeral is 2 constitutes the transmission mechanism) will be described below. Such as figure 1 and 2 As shown, the transmission mechanism includes: a handle 21, a lever 22, a push rod 23, a lock 24 and a trip lever 25, wherein: the handle 21 is connected with the lever 22, and the handle 21 receives the input closing co...

Abstract

The invention relates to a tripping device used for receiving a shunt trip signal and cutting off a power supply of an external small breaker. The tripping device comprises a shell, and a tripper (1) and a transmission mechanism which are arranged inside the shell, wherein the tripper (1) comprises a coil, an iron core and a biasing spring; and the transmission mechanism comprises a handle (21), a lever (22), a push rod (23), a lock catch (24) and a tripping lever (25). The transmission mechanism of the tripping device is designed more concisely and reasonably and can achieve the perfect transmission effect; furthermore, the tripping device controls two circuit states through the tripper, well utilizes the weak current of an electronic circuit to control undervoltage and a voltage loss circuit and achieves the effective energy-saving effect.

Description

technical field [0001] The invention relates to an accessory product of a miniature circuit breaker, in particular to a tripping device, which can be used for shunt tripping and undervoltage tripping. Background technique [0002] The miniature circuit breaker is a very important switching device with comprehensive performance in the power system, especially the terminal power system. Therefore, the accessory products that can control the power on and off of its main circuit have emerged as the times require, and are especially Importantly, it enables the circuit breaker to better perform various protective functions. [0003] Accessory products generally include: release, transmission mechanism and undervoltage protection module, etc. [0004] The transmission mechanism in the accessory product is used to control the tripper so as to trip the miniature circuit breaker so as to realize on-off control of the main circuit power supply of the miniature circuit breaker. At pre...
