Power supply lines are the components with massive failures in the power system. The faults are mostly transient faults, occupying about 80% to 90% of the total number of faults, from which we can know that it is quite possible to overlap the disconnected lines successfully. The circuit reconnection can be done manually, but the effect is not significant for the excessive blackout time.
To improve the reliability of power supply lines, the automatic reclosing device is usually applied to the operation of disconnected lines instead of the manual way. Automatic reclosing is a protective function of a miniature circuit breaker and an automatic device that automatically switches the circuit breaker tripped due to faults into operation as required. The application of automatic reclosing can improve the segmentation and over-current capacity of the power system, improving the continuity and quality of the power supply for users. The product is mainly used in industrial, commercial, high-rise residential buildings and other buildings with stable and reliable operation.
The miniature reclosing motor is a miniature gear motor product applied to electrical circuit switch. The main transmission structure consists of a drive motor and a gearbox. ZHAOWEI gear motor for automatic reclosing adopts multistage helical worm gears. It can adjust the transmission structure for automatic reclosing, optimize the performance and prolong the service life, achieving intelligent opening and closing of the circuit breaker.
Technical parameters of gear motor for reclosing are different in different fields, therefore gear motor for the automatic reclosing device is developed with customized technical parameters. For example, the drive motor can adopt a DC motor, brushed motor, brushless motor, stepper motor and coreless motor as the drive source, and the gearbox can use the planetary gearbox, normal gearbox, worm gearbox, and cylindrical gearbox as the reduction device. ZHAOWEI provides customization service according to different requirements of technical parameters, including output speed, power, voltage, current, reduction ratio, torque, diameter and gear materials.
