A High Power Spring Operating Mechanism for High Voltage Circuit Breaker

Abstract

The present invention relates to a high-voltage circuit breaker high-power spring operating mechanism. A switching-off energy storage spring system and a switching-on energy storage spring system which are parallel to each other in a vertical direction are arranged between a left wall plate and a right wall plate; the switching-off energy storage spring system is connected with a piston rod for output operation; an energy storage transmission system is distributed on the outer walls of the left wall plate and the right wall plate; the main shaft of the energy storage transmission system passes a space between the two wall plates; the main shaft of the energy storage transmission system is connected with the switching-on energy storage spring system at the right wall plate so as to provide switching-on energy storage operation and provides switching-off energy storage operation for the switching-off energy storage spring system at the left wall plate in a hook surface sliding contact manner; a switching-off pulling sub-system is arranged at the outer wall of the right wall plate; an switching-on pulling sub-system is arranged at the outer wall of the right wall plate; an output shaft system is arranged at the inner sides and two outer walls of the left wall plate and the right plate wall and is connected with the energy storage transmission system, the switching-off energy storage spring system and the switching-on energy storage spring system; and the main shaft of the output shaft system passes through the space between the two wall plates and is of a sleeved type half shaft structure and can be in linkage with the switching-off energy storage spring system and the switching-on energy storage spring system.

Description

technical field [0001] The invention relates to a high-power spring operating mechanism of a high-voltage circuit breaker, which belongs to the technical field of high-voltage power transmission and transformation. Background technique [0002] The operating mechanism is one of the important equipment of the high-voltage circuit breaker and an important part of the high-voltage circuit breaker. The opening and closing operations of the high-voltage circuit breaker are realized through the operating mechanism. At present, the types of operating mechanisms of high-voltage circuit breakers in the high-voltage switch industry are mainly hydraulic and spring operating mechanisms. The hydraulic operating mechanism has precise control, time control for opening and closing within two weeks of waves, and stable mechanical characteristics. Higher advantages, but at the same time, there are complex structures of the product, the two-point speed is lower than one-point speed in the recl...

AI Technical Summary

Problems solved by technology

[0003] Currently used in the field of high-voltage circuit breakers, there is already a demand for using spring operating mechanisms in high-level voltage products. Due to the mechanical characteristics of the spring itself and the corresponding transmission structure characteristics of the spring operating mechanism, the spring operating mechanism is different from the spring operating mechanism. The mechanical stress matching of the output characteristics of the high-voltage circuit breaker is in a poor state, and the spring operating mechanism itself has a large overall volume, most of the energy storage components are in a critical limit use state, the transmission efficiency is low, the output characteristics are poor, and the manufacturing process is difficult. Poor quality assurance and other problems, and it is difficult to meet the product requirements of high-power operating power, thus limiting the scope of use of the spring operating mechanism
