Abstract

The invention discloses an electric spring-operated mechanism which solves the problem of troublesome product assembling and debugging and small application range caused by that a conventional spring-operated mechanism only has a switching-on function. The electric spring-operated mechanism comprises two lateral plates and a reinforcing rib, wherein a cavity for accommodating a switch-off mechanism is formed between the reinforcing rib and one of the lateral plates, the switch-off mechanism comprises a driving shaft, a switch-off crank arm and a switch-off spring, the driving shaft is in linked connection with a driver board on a switch-on mechanism, the switch-off crank arm is arranged on the driving shaft in a sleeved manner and is linked with the driving shaft, and the switch-off crank arm is connected with the switch-off spring. In the invention, since the switch-off mechanism is additionally added, the switch-off and switch-on functions are provided at the same time, switch-off and switch-on debugging is simple, product performance is ensured, when being assembled and used with other electric equipment, the electric spring-operated mechanism has the advantages that the assembling is convenient, the mechanical property is reliable, strong operating power is provided, and the electric spring-operated mechanism can be used for high-voltage and extra-high voltage circuit breakers and totally closed composite electric appliances.

Description

technical field [0001] The invention relates to an electric spring operating mechanism, which is suitable for circuit breakers and fully enclosed combined electrical appliances in high-voltage and ultra-high-voltage power systems. Background technique [0002] In order to meet the needs of sustainable development and environmental protection, my country's power transmission and transformation has developed rapidly, especially the 1000KV ultra-high voltage transmission ranks at the leading level in the world. UHV power equipment such as circuit breakers and fully enclosed combined electrical appliances have been domestically produced, but the operating mechanisms in such equipment must replace foreign hydraulic spring mechanisms, and hydraulic spring mechanisms also have the defect of oil leakage. The spring operating mechanism is a mechanical operating mechanism with an energy storage spring as an energy storage element. The energy storage of the spring is completed by mean...
