Problems solved by technology

However, in the actual use process, it is found that the manual opening device still has shortcomings: 1) only one side of the support plate is equipped with a spring, and the moving parts are unbalanced in force, which is likely to cause serious wear and affect the service life; 2) the handle is directly connected The drive shaft and the handle require a large torque when operating, and the operation is laborious, and manual opening is not flexible when used for high-power switching

Embodiment Construction

[0016] Such as figure 1 , as shown in Figure 2, the high-power switch permanent magnet operating mechanism of the present invention includes a permanent magnet switch operating mechanism and a manual opening device connected to the output shaft 2 of the permanent magnet switch operating mechanism. The shell 1 of the permanent magnet switch operating mechanism is provided with an output shaft 2, the output shaft 2 protrudes through the end caps 15 at both ends of the shell 1, its front end is connected with the actuator through a connecting pin, and the rear end is fixedly connected with an end cap 9. The materials of the shell 1 and the end cover 15 are all ferrous which is easy to conduct magnetism. The contact part between the output shaft 2 and the shell 1 is fitted with an anti-magnetic bushing, and the middle section of the output shaft 2 located inside the shell 1 is fixedly installed with an iron core 3, and the outer side of the iron core 3 is provided with a permanent...

Abstract

The invention discloses a permanent-magnetic operational structure of large-power switch, which is characterized by the following: the output shaft is plugged in the end lid, which connects the support board on two sides of output shaft to parallel the output shaft; the end cap connects the back of output shaft; the driving shaft can be plugged on the support board movablely with cam fixing on the driving shaft between end cap and end lid; the hand-operated braking spring is connected between cam and support board; the driving shaft connects the hand-operated crank; the driven gear is loaded on the driving shaft, which engages positive gear on the support board, which is fixed on one end of driving shaft; the driving shaft can be plugged on the support board rotatably, whose the other end connects operational crank.

Description

technical field [0001] The invention relates to an operating mechanism of a power switch, in particular to a permanent magnet operating mechanism of a high-power switch. Background technique [0002] Most of the existing power switches are opened and closed by an electromagnetic operating mechanism or a spring operating mechanism. The disadvantage of the electromagnetic operating mechanism is that an additional mechanical locking device is required, which has a complex structure, high failure rate, high noise, and is difficult to use. The service life is short; the spring operating mechanism needs to be driven by a motor and locked mechanically, with complex structure, heavy weight, inflexible movement, loud noise and high failure rate. In addition, a monostable operating mechanism has appeared in recent years. This form of operating mechanism is more complicated than the bistable one. In particular, the manual opening device basically uses the traditional tripping principle...
