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 is intelligent high-voltage switch cabinet?

Intelligent high-voltage switch cabinet is equipped with electric earth switch, electric chassis car, intelligent vacuum circuit breaker and other components. It is the basis for realizing the “remote control” function.

How many compartments does the intelligent high-voltage switch cabinet have?

The intelligent high-voltage [ 2] switch cabinet is divided into four independent compartments: bus room, instrument room, circuit breaker room and cable room. The protection grade of the cabinet is IP4X, as shown in Fig. 3. Intelligent high voltage switchgear diagram

What is a high voltage switch cabinet?

The traditional high voltage switch cabinet is mainly composed of isolation switch, earthing knife-switch, current transformer, surge arrester, vacuum circuit breaker, interlocking mechanism, live display, ammeter, signal indicator light, transfer switch, electromagnetic lock and cabinet body. The protection level of cabinet body is IP2X.

What is the surface heat transfer coefficient of a switchgear cabinet?

The switchgear cabinet surface is set as the third boundary condition, with surface heat transfer coefficient h = 10 W/ (m 2 ∙K). Surface-to-surface radiation occurs between the conductive circuit, insulated component, and the cabinet wall, where the conductive circuit surface emissivity is ε2 = 0.5.

Can high-voltage switchgear improve the reliability and safety of power supply?

In order to improve the reliability and safety of power supply and reduce the failure rate of switchgear, this paper designs a novel high-voltage switchgear which is reliable and safe.
