Embodiment approach

[0027] figure 1 A switching device 1 of the present invention is schematically shown, which includes a switching mechanism 2, a motor M and a gearbox G connecting the switching mechanism 2 and the motor M. One end of the joystick 26 of the switching mechanism 2 is connected to one stage of the gearbox G, and the other stage of the gearbox G is connected to the motor M. Switching device 1 also includes two switches, that is, switch S1 and switch S2, both of which are side-operated switches (for example, a side-operated isolating switch, which can also be a circuit breaker), wherein the switching mechanism 2 is located between switch S1 and switch S2 side and connect to Switch S1 and Switch S2. The switching mechanism 2 includes two driven gears, namely a driven gear 21 and a driven gear 23 , and an incomplete gear as a driving gear 22 . The driving gear 22 is located between the driven gear 21 and the driven gear 23 , and the bevel gear 24 and the switches S1 and S2 are locat...

Abstract

The invention relates to a switching device, which comprises two switches and a switching mechanism, wherein the switching mechanism is used for switching off or switching on the two switches, and both of the two switches are side operation switches. The switching mechanism is connected with the side surfaces of the side operation switches and comprises two driven gears and a driving gear. One driven gear is respectively arranged on a driving rod of each side operation switch, the driving gear is positioned between the driven gears, and the driving gear only drives one driven gear to rotate for switching off or switching on one corresponding switch at any time. The switching device has the advantages that the structure is compact, the design is simple and reliable, the switching device is particularly suitable for the side operation switches, and the modularization can be realized.

Description

technical field [0001] The invention relates to a switching device, in particular to a switching device for a side-operated switch. Background technique [0002] In the electrical field, it is often necessary to switch between two switches. For example, in order to provide uninterrupted power supply to some important places, an automatic switching device is often used to switch between the normal power supply and the backup power supply. Such an automatic switching device generally includes two switches (such as two isolating switches or two circuit breakers) and a switching mechanism for operating the two switches, and it is ensured that the two switches cannot be closed at the same time. [0003] Chinese patent CN2236684Y discloses a switching device, which has two front operation switches and a switching mechanism located between the two front operation switches. Although the size of the switching device in the longitudinal direction is relatively small, it is difficult ...
