Embodiment Construction

[0009] The present invention will be further explained below.

[0010] The method of the present invention for improving the efficiency of processing closing bounce based on reducing the closing speed includes a circuit breaker. The vacuum circuit breaker has a closing spring, an opening spring, and a closing coil. The circuit breaker is a low oil circuit breaker. For SW2-35, the length of the closing spring on the circuit breaker is set to 128mm, and the length of the opening spring is set to 970mm.

[0011] The present invention not only adjusts the length of the closing spring to adjust the force of the closing spring to achieve the purpose of reducing the closing speed, but also reduces the closing speed by reducing the terminal voltage of the closing coil and adjusting the pre-tension length of the opening spring. Brake speed.

[0012] Through the above scheme, the effect of reducing the closing speed can be achieved, and the purpose of processing the closing bounce efficiency ...

Abstract

The invention discloses a closing speed reduction based method for improving the processing efficiency of closing bounce, comprising a circuit breaker. A closing spring and an opening spring are arranged on the circuit breaker; and the circuit breaker is a low-oil circuit breaker, the length of the closing spring on the circuit breaker is 128mm, and the length of the opening spring is 970mm. By regulating the length of the closing spring, the invention can regulate the power of the closing spring, reduce the end voltage of a closing coil, regulate the prestretching strength of the opening spring so as to reach the aim of improving the processing efficiency of the closing bounce, shorten the time for eliminating the closing bounce and decrease the closing bounce frequency through maintenance and overhauling.

Description

Technical field [0001] The invention relates to a circuit breaker, and in particular to a method for improving the efficiency of handling closing bounce based on reducing the closing speed. technical background [0002] The circuit breaker is named after its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no need for maintenance of arc extinguishing. The application is more popular. [0003] When testing the characteristics of the circuit breaker, it was found that some test data exceeded the standard. Among them, the closing bounce data took the first place in the number of exceeding the standard. How to improve the efficiency of handling the closing bounce is a problem that the inventor of this application has devoted to research. . Summary of the invention [0004] The purpose of the present invention is to overcome the defe...
