Electric spring operating mechanism

Abstract

The invention relates to an electric spring operating mechanism belonging to the technical field of a high-voltage power switch. The electric spring operating mechanism comprises a base, a motor, a transmission shaft assembly, a lead screw assembly and a spring assembly, wherein the transmission shaft assembly is fixedly arranged on the base; one end of the spring assembly is connected with the base, and the other end of the spring assembly is connected with the transmission shaft assembly; both ends of the lead screw assembly are fixedly arranged on the base and are connected with the transmission shaft assembly; and the motor is connected with the lead screw assembly in a meshing mode. The invention satisfies the driving task of a fast grounding switch in a GIS (Gas Insulated Switchgear) so as to achieve the functions of fast switching-on and slow switching-off of the fast grounding switch. Besides, the electric spring operating mechanism has the advantages of simple structure, beautiful appearance, stable performance and high reliability.

Description

Electric Spring Operating Mechanism technical field The invention relates to a device in the technical field of high-voltage power switches, in particular to an electric spring operating mechanism. Background technique The grounding switch driven by the electric spring mechanism can make the switch contacts move quickly, so as to realize the function of closing the short-circuit current. It is an indispensable device for high-voltage switchgear. The basic principle is that the motor drives the spring to store energy after being decelerated by the deceleration device, and the stored energy spring releases energy after passing the dead point to drive the switch contact to move quickly. After searching the prior art, it is found that in the existing electric spring operating mechanism, the overall external dimension is too large. In addition, the existing operating mechanism adopts the principle of quick opening and quick closing, that is, a symmetrical form, that is, the o...

After searching the existing technology, it is found that the overall dimensions of the existing electric spring operating mechanism are too large

In addition, the existing operating mechanism adopts the principle of quick opening and quick closing, that is, a symmetrical form, that is, the opening and closing are all completed by releasing energy from the spring. This method is not conducive to the opening operation. In order to be able to open the gate, the spring force must be increased. , which causes the closing speed to be too fast and the vibration to increase, which is not conducive to the mechanical life of the switch body and the mechanism

At the same time, the processing cost of the existing base and shell is high, and the assembly efficiency is low due to inaccurate positioning and splint deformation.
