Embodiment Construction

[0016] Figure 1 to Figure 5 , shows the operating mechanism of the switch driving device according to an embodiment of the present invention, the operating mechanism includes the driver 2, the driver wheel 11 and the spring combination device 13 assembled in the frame 1.

[0017] Frame 1, driver 2 and spring combination device (13, 21), etc., the driver (2) not only has I (closing) position, O (opening) position, but also has II (idle stroke) position, I position and II position Can be respectively relative to the O position, in the opposite direction to form a predetermined angle (α I 、α II )position.

[0018] The driver 2 can rotate in the hole (20) of the frame, and drive the driving wheel 11 on the driver 2 to rotate together. The first end support seat 14 of the spring combination device 13 is clamped on the frame 1. In the spring combination device 13 The second end 6 and the spring 8 can rotate around the boss 23 on the supporting seat 14 with a circular arc surface...

Abstract

The invention discloses a switch driving device, which comprises a frame (1), a driver (2), a spring combination device (13) and the like. As the rotating wheel (11) on the driver (2) is provided with two cylinders (7 and 9) which can enable notches (4, 10) on the spring combination device (13) of the driver to be engaged or separated in a rotating mode, the driver (2) not only has an I (closing) position and an O (closing) position but also an II (idle stroke) position, and the I position and the II position can be positioned respectively in relative to an O position and at preset angles (alpha I, alpha II) in opposite directions.

Description

technical field [0001] The invention relates to a switch drive according to the claims. Background technique [0002] Switching devices generally have an O position and an I position, wherein in the O position the poles of the switching device are open (open), and in the I position the poles of the switching device are closed (closing). The position of the poles of the switching device is changed by rotating the main shaft of the switching device. In order to rotate the main shaft of the switch, it is necessary for the switch drive to have an O-position and an I-position corresponding to the O-position and the I-position of the switching device. When some switching devices are combined into other uses, such as combined into a transfer switch, it is also necessary to have an idle position (II), in which the pole of the switching device is always open. [0003] In known switching devices, there is the problem that the free travel position is difficult to achieve. In some kn...
