Abstract

The invention discloses a spring operating mechanism. The spring operating mechanism comprises a frame, a transmission connecting lever and a closing cam, wherein the frame is provided with an opening buffer and a closing buffer which are mutually independently arranged, the opening buffer comprises an opening cylinder body and an opening piston rod, the opening piston rod is provided with a hinged long hole for hinged connection with the transmission connecting lever, the closing buffer comprises a closing cylinder body and a closing piston rod, the closing piston rod is provided with a roller for rolling cooperation with the closing cam during closing operation, at the early stage and the middle stage of closing, the roller is in rolling fit with the concentric portion of the closing cam, and at the late stage of the closing, the roller is in rolling fit with the eccentric portion of the closing cam. According to the invention, the opening buffer and the closing buffer are mutually independently arranged, compared to a mode of an integrated buffer, the processing and manufacturing are easier, the installation and debugging are convenient, and the buffer performance of the buffers can be conveniently debugged.

Description

technical field [0001] The invention relates to the field of high-voltage circuit breakers, in particular to a spring operating mechanism. Background technique [0002] The operating mechanism is an important equipment in the field of high-voltage power transmission and transformation, and is 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. The operating mechanism of high-voltage circuit breakers is mainly divided into two types: hydraulic operating mechanism and spring operating mechanism. The hydraulic operating mechanism has the advantages of short opening and closing time and stable performance, but it also has complex structure, high cost, and easy leakage Oil, easy to be affected by the use of the environment and other disadvantages. The spring operating mechanism does not have the problem of oil leakage, and has the characteristics of low cost, s...
