Switch cabinet switch spring has no energy storage

Why do switches use a spring?

Generally, switches use a spring to open and close the circuit as fast as possible to avoid arcing. The spring force is also used to minimize bouncing of conductors when they strike each other. In short, a spring is used in a switch to create a toggle mechanism. This is my current understanding.

How does an energy storage spring work?

When closing is required, the positive transmission of the motor drives the clutch gear to rotate, thus driving the transmission gear and large shaft to rotate to the dead point of the energy storage spring, the position switch automatically switches the motor, and the earth switch quickly closes under the action of the energy storage spring.

What are the functions of elastic storage device using spiral spring?

The principal functions of elastic storage device using spiral spring are energy storage and transfer in space and time. Elastic energy storage using spiral spring can realize the balance between energy supply and demand in many applications.

Can mechanical spring systems store macroscopic energy?

Mechanical spring systems’ benefits and limits for storing macroscopic amounts of energy will be assessed and their integration with mechanical and electrical power devices will be discussed. 1876-6102 © 2015 The Authors.

Can mechanical springs be used for energy storage?

As far as mechanical energy storage is concerned, in addition to pumped hydroelectric power plants, compressed air energy storage and flywheels which are suitable for large-size and medium-size applications, the latest research has demonstrated that also mechanical springs have potential for energy storage application .

How do you close a power switch?

To close the switch, the handle is inserted into the spring charging cam, then rotated upward through an angle of 120 degrees. This action charges the operating spring, and as the mechanism is forced past toggle, the stored energy of the spring is released and transferred to the main shaft that snaps the switch closed.
