Problems solved by technology

At present, most high-voltage circuit breakers use spring operating mechanisms with large operating power, which have problems such as poor reliability of energy storage systems, tripping systems, and buffer systems, inconvenient maintenance, many parts in the transmission system, and inconvenient observation of indicators. The requirements for high reliability of circuit breakers are not compatible, and defects such as abnormal energy storage, abnormal opening and tripping, and oil leakage of oil buffers often occur, which affect the improvement of the reliability of high-voltage circuit breakers.

Abstract

The invention provides a high-voltage breaker spring operating mechanism and a transmission device. The mechanism comprises a mechanism support, a transmission component, an energy conversion component, an opening control component, an energy storage component, a closing spring component, a closing control component, an opening spring component and a buffer, wherein the transmission component, theenergy conversion component, the opening control component, the energy storage component, the closing spring component, the closing control component, the opening spring component and the buffer arearranged on the mechanism support; the closing spring component is driven to store energy during action of the energy storage component; the energy conversion component comprises an output shaft and an output crank; the transmission component comprises a main shaft, a middle crank and driving cranks arranged at the two ends of the main shaft, wherein the driving cranks are connected with a breakerthrough driving rods; one end of the output crank is connected with the opening spring component and the middle crank, and the other end of the output crank is connected with the buffer; during closing operation, the closing spring component releases energy, the output crank drives the transmission component to drive the beaker to be closed; and during opening operation, the opening spring component releases energy, and the output crank drives the transmission component to drive the breaker to be open. The mechanism is reasonable in design, compact in assembling, convenient to observe and maintain, high in reliability and worth of popularization.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation equipment, in particular to a spring operating mechanism and transmission device of a high-voltage circuit breaker. Background technique [0002] High-voltage circuit breakers are the most critical control and protection equipment in high-voltage power grids, and play an important role in the operation safety of high-voltage power grids. At present, with the increase of voltage, circuit breaker products with a voltage level of 220kV three-phase linkage circuit breaker and above need to be equipped with an operating mechanism with tens of thousands of joules of opening operation work. At present, most high-voltage circuit breakers use spring operating mechanisms with large operating power, which have problems such as poor reliability of energy storage systems, tripping systems, and buffer systems, inconvenient maintenance, many parts in the transmission system, and inc...
