Abstract

The invention discloses a high-voltage circuit breaker spring preparation process, mainly comprising the following steps: sorting, blanking, tip grinding, heating, spring coiling, quenching treatment,tempering treatment, end face grinding treatment, shot blasting, flaw detection, erection treatment, surface treatment, marking and packaging; wherein a thermal compression treatment is performed onthe spring subjected to the tempering treatment by using a thermal compression device. In the high-voltage circuit breaker spring preparation process disclosed by the invention, the thermal compression treatment is performed on the spring subjected to the tempering treatment, so that the performance of the spring is improved, and the precision is improved.

Description

technical field [0001] The invention relates to the technical field of spring preparation, in particular to a high-voltage circuit breaker spring preparation process. Background technique [0002] High-voltage circuit breakers are the main parts of high-voltage power transmission and transformation equipment. Whether they can operate safely plays a key role in ensuring the safe, stable and reliable operation of the entire high-voltage power transmission and transformation network. The high-voltage circuit breaker spring is the core of the operating mechanism. Parts, its importance can be seen. Due to the reliability of the spring operating mechanism of the circuit breaker, the requirements for the spring load deviation are generally very high, which are generally higher than the super precision of the national standard. After the spring is pressed for 24 hours, the free height change is ≤1%×Ho, and the P2 load change is ≤ 2% x P2. It is also required that after the spring ...
