Problems solved by technology

Since the isolating switch needs to be positioned reliably in the sub-position and closing position, and the electric operation device requires both electric and manual operation, the design of the operation device is complicated.
At the same time, when double isolating switches are required in the power distribution switchgear, they need to be interlocked with each other, making it difficult to guarantee reliability.

Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0013] As shown in Figure 1, the dial 1 is driven by the gear to rotate clockwise. When the dial shaft 4 enters the notch 5 of the first bat board 2, the first bat board 2 will rotate with the dial 1 until the dial shaft 4 is disengaged. The notch 5 of the first bat plate, so far the first bat plate 2 drives the first isolating switch operating rod 7 to rotate 90 degrees through the rotating shaft, and the first isolating switch is closed. Closed, and embedded in the groove 9 on the side of the shifting plate 1, so that the first bat plate 2 remains still, and the first isolating switch is in a locked state at the closing position. Similarly, the dial 1 continues to rotate clockwise. When the dial shaft 4 enters the slot 6 of the second bat board 3, the second bat board 3 rotates with the dial 1 until the dial shaft 4 leaves the slot 6 of the second bat board...

Abstract

The invention relates to a motor operation apparatus of dual-isolated switch, comprising motor, bat-typed plate, moving plate and gear, whose characteristics is: motor connected to moving plate through gear group will drive moving plate rotating , a on the moving plate will orderly match with notch the first and second bat-typed plate to drive them revolving, and the first and second bat-typed plate are connected separately to operating arm of the first and second separated dual-isolated switches through rotating shaft . The whole structure seams simple and compact, by toggling notch of bat-typed plate through to control the switch and the switch is locked by bat-typed plate and the circular edge of. In addition, the whole operation is clear and under stainable because that moving plate toggles the two bat-typed plate separately which is firstly to the first dual-isolated switches and then the second one and the opposite operation to close the switches, just adapts to people's custom.

Description

technical field [0001] The invention belongs to an operating device for separating and closing two isolating switches in a power distribution switch cabinet, in particular to an electric operating device for upper and lower double isolating switches in a longitudinal switch cabinet. Background technique [0002] At present, the isolating operating device used to separate and combine two isolating switches in the power distribution switchgear is generally a manual operating device. Even if there is an electric operating device, only a single isolating switch can be operated. Since the isolating switch requires reliable positioning in the dividing and closing positions, and the electric operating device requires both electric and manual operation, the design of the operating device is complicated. At the same time, when double isolating switches are required in the power distribution switchgear, they also need to be interlocked with each other, making it...
