Embodiment Construction

[0037] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0038] An embodiment of the circuit breaker in the present invention is as follows Figure 1~Figure 3 As shown, a mechanism box 10 with a door panel 12 is included, and a permanent magnet mechanism 20 and a permanent magnet mechanism manual opening device 30 are arranged in the mechanism box 10 . The permanent magnet mechanism 20 includes a guide rod 21, that is, a moving main shaft. The permanent magnet mechanism manual opening device 30 includes a device seat 31 , an operating shaft 32 , a cam 33 , an adapter shaft 35 , an adapter shaft mounting sleeve 40 , a torsion spring 41 and an operating handle 42 .

[0039] The device seat 31 includes a main body support plate 311 and a bent support plate 312 arranged on the edge of the main body support plate 311. figure 1 Viewed from the angle shown, the front and right edges of the main body support plate...

Abstract

The invention relates to a permanent magnetic mechanism manual brake separating device and a circuit breaker using the device. The permanent magnetic mechanism manual brake separating device comprises a rotating shaft hinge articulated seat for an operation rotating shaft to be assembled in a rotating manner and a device seat, wherein the rotating shaft articulated seat is fixed on the device seat; and a mechanism case fixed structure for being fixedly connected with a mechanism case of a permanent magnetic mechanism is arranged on the device seat. The permanent magnetic mechanism manual brake separating device also comprises a coupling shaft arranged in the rotating manner, and the operation rotating shaft and the coupling shaft are connected through a transmission structure. Thus, an independent rotating shaft articulated seat mounting base is formed on the device seat, and the structural strength is guaranteed, so that the rotating shaft articulated seat is prevented from being displacement relatively; moreover, the operation rotating shaft of the structure can adopt shorter length, the structural strength of the rotating shaft articulated seat mounting base is guaranteed, and then the travel accuracy of a cam on the operation rotating shaft is guaranteed, clamping stagnation of the operation rotating shaft is avoided, or no reset of the operation rotating shaft after brake separating is avoided, the required external force for brake separating is little, and the reliability is high.

Description

technical field [0001] The invention relates to a permanent magnet mechanism manual opening device and a circuit breaker using the device. Background technique [0002] The permanent magnet mechanism is favored by users for its simple structure, reliability and long life. Its control is completely realized by electronic control. The manual opening device of the magnetic mechanism, that is, the mechanical manual opening device, is indispensable, and its realization forms are also diverse. [0003] The existing permanent magnet mechanism manual opening device, such as the Chinese patent with the authorized announcement number CN 103903920 B, discloses a manual opening device for a permanent magnet mechanism, including a fixed installation part and an operation control part, wherein the fixed installation part is composed of a permanent magnet The mechanism box of the mechanism is formed, which is divided into the first fixed installation plate and the second fixed installatio...
