An automatic reclosing transmission mechanism

Abstract

The invention discloses an automatic reclosing lock transmission mechanism. A controller comprises a controller shell, a linkage rod, a worm gear, a switch button, a worm and a motor controller, so that the width of the controller is less than or equal to 36mm; the linkage rod moves and rotates between two bosses; the two bosses drive the linkage rod to rotate in two different directions; a worm is fixedly sheathed with the motor controller; and the worm with helical teeth is in teeth engaged transmission with the worm gear with teeth. Therefore, a motor drives the transmission of the worm and the gear to control the rotating direction of the linkage rod. With adoption a worm transmission mechanism, the volume of a product is reduced, and the width of the product is less than or equal to 36mm, thereby guaranteeing the precision and the stable running of worm transmission. Therefore, the automatic reclosing lock transmission mechanism is capable of controlling the automatic disconnection and closure of the product so as to realize remote control.

Description

technical field [0001] The invention relates to a reclosing intelligent controller, in particular to an automatic reclosing transmission mechanism. Background technique [0002] With the promotion of the smart grid, small circuit breakers and residual current operated circuit breakers that require manual operation can no longer meet the requirements of the smart grid, and must be matched with automatic reclosing products, so that the circuit breaker will give a signal to the recloser after a fault or malfunction , can make the circuit breaker close automatically, without the need for maintenance workers to close the switch manually, realize remote control, and effectively save manpower and material resources. [0003] At present, there are automatic reclosing products in the market, and the main mechanisms are: 1. Directly use the motor drive to drive the linkage mechanism to realize the automatic closing of the circuit breaker; 2. Use the steering gear and the spur gear to ...

AI Technical Summary

Problems solved by technology

[0005] Through the above explanations, it is found that the mechanism has the disadvantages of many parts, complex process, difficult assembly and low production efficiency. There are many parts in the product, and there are many factors affecting the reliability of the product, resulting in low product reliability; difficult assembly, complex process and Low production efficiency; adopt bevel gear transmission, the product volume is large, the product width is up to 54mm, and there are many consumables, which increase the cost of end users, which is not conducive to energy saving and consumption reduction. The high cost is difficult for ordinary users to bear and is not conducive to promotion
