An energy storage output mechanism for a spring operating mechanism

Abstract

The invention provides an energy storing outputting mechanism applied to a spring operating mechanism. The energy storing outputting mechanism comprises a frame body, a rotating shaft which is arranged at one end of the frame body, and an output connecting lever which is arranged at the other end of the frame body; an energy storing biasing part sleeves the rotating shaft; a reducing structure of which the radius is gradually varied from long to short is also arranged on the rotating shaft and integrally rotated with the rotating shaft. The energy storing outputting mechanism further comprises a transmission chain or rope, wherein the transmission chain or rope is arranged about the sidewall of the outer edge of the reducing structure; one end of the transmission chain or rope is connected with the reducing structure, and while the other end is connected to the output connecting lever. With the adoption of the energy storing outputting mechanism with such structure applied to the spring operating mechanism, the problem that the output force of the outputting mechanism of the spring energy storing mechanism in the prior art is reduced to cause unreliable closing and enable an energy storing spring to be easily fatigued when the spring releases energy can be solved; the energy storing outputting mechanism meets the closing curve of a switch when closing the switch, the service life of the energy storing spring is prolonged, and reliable closing is ensured.

Description

technical field [0001] The invention relates to an energy storage output mechanism for a spring operating mechanism, belonging to the technical field of high-voltage switchgear. Background technique [0002] High-voltage circuit breaker is an important switchgear in the power system. It is responsible for the dual tasks of controlling and protecting the circuit. Its performance is one of the important factors that determine whether the power system can safely supply power. There are different advantages and disadvantages in terms of performance. Due to the use of vacuum arc extinguishing technology, vacuum circuit breakers have the advantages of no pollution to the environment, low power of the operating mechanism, long service life, safety and reliability, and convenient maintenance. Development; the operating mechanism is an important part of the high-voltage circuit breaker, which has various types, such as spring operating mechanism, pneumatic mechanism, hydraulic mechan...

Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that when the output mechanism of the spring energy storage mechanism in the prior art releases energy from the spring, the output force becomes smaller, resulting in a The phenomenon of unreliable brakes and the fatigue of energy storage springs provides an energy storage output mechanism that conforms to the closing curve of the switch during the closing process of the switch, prolongs the service life of the energy storage spring, and ensures reliable closing
