How many types of high-voltage switch operating mechanisms are there? The following answers!!

1. Manual operation mechanism

The manual operation mechanism is to use manpower to operate the high-voltage switchgear, and most of the products of this mechanism are equipped with a back-evaluation, which is so that when the equipment fails, manpower can be used to let the equipment continue to run and avoid being stuck in one place;

2. Electromagnetic operating mechanism

The electromagnetic operating mechanism is the operating mechanism that uses the principle of electromagnet closing, and the closing energy of this product depends on the size of the current, so the current required when using this mechanism is larger;

3. a spring operating mechanism

The spring operating mechanism can use manpower, or it can use a motor to make the spring mechanism energy storage so as to realize the closing mechanism, but this mechanism is generally carried out by the motor, and manpower rarely appears;

4. an electric operating mechanism

This electric operating mechanism is a mechanism that uses the motor as a principle to realize opening and closing;

5. Pneumatic operating mechanism

Compressed air is used as a principle to push the piston inside to open and close.
