Vacuum circuit breaker spring mechanism energy storage transmission and clutch system

Abstract

The invention discloses a vacuum circuit breaker spring mechanism energy storage transmission and clutch system which comprises a main frame, the main frame comprises a left side plate and a right side plate, a plurality of side plate supporting rods are installed between the left side plate and the right side plate, an energy storage assembly and a clutch assembly are installed in the main frame, and the energy storage assembly is connected with the clutch assembly through a transmission assembly. The energy storage assembly is connected with an energy storage motor installed on the outer wall of the right side plate, the clutch assembly is connected with an energy storage shaft penetrating through the left side plate and the right side plate, and a clutch pin is arranged on the outer side of the clutch assembly. A cam is installed on the right end portion of the energy storage shaft, and an energy storage maintaining latch fixed to the right side plate is arranged on one side of the cam. According to the system, the transmission shaft, the transmission assembly and the clutch assembly are driven by the motor to rotate for energy storage, the transmission assembly and the clutch assembly are simple, scientific and reasonable in structure, parts are reduced, the part machining and assembling difficulty is lowered, and the production cost is effectively saved.

Description

technical field [0001] The invention relates to the technical field of medium voltage electrical appliances, in particular to a vacuum circuit breaker spring mechanism energy storage drive and clutch system. Background technique [0002] In the field of medium voltage vacuum circuit breakers, the spring operating mechanism is the mainstream circuit breaker operating mechanism and is the most widely used. The current mainstream circuit breaker operating mechanism energy storage systems mainly have several forms: 1. Multi-group gear pair transmission, the clutch adopts the form of an overrunning clutch. This structure requires high dimensional accuracy and material of the clutch parts, and the number of parts reaches more than 20. , of which there are more than 10 high-cost bearings, copper sleeves, etc., so the price is high. Such as EVH series circuit breaker spring mechanism. 2. The energy storage clutch in the form of a ratchet and pawl is relatively simple in structure,...

AI Technical Summary

Problems solved by technology

2. The energy storage clutch in the form of ratchet and pawl is relatively simple, but the disadvantage is that the energy storage process is not stable, there are back and forth frustrating phenomena, and the noise is very loud

This kind of structure has a large number of parts, and the assembly and structure are more complicated.
