Multifunctional switch apparatus with automatic reclosing function

Abstract

The invention relates to a multifunctional switch apparatus with an automatic reclosing function, which comprises a switch body, and a controller with the automatic reclosing function, wherein the switch body comprises a main circuit contact arc-extinguishing system, an electromagnetic system and an operating mechanism, and the controller with the automatic reclosing function comprises a microprocessor circuit, a signal acquisition circuit, a power circuit, a man-machine interface circuit and a driving and controlling circuit. In the multifunctional switch apparatus provided by the invention, a simple electric component can replace several components of the traditional power distribution system, and the automatic reclosing function is provided, so after faults occur, reclosing can be carried out after delay, thereby ensuring the continuity of power supply.

Description

technical field [0001] The invention relates to a switching device, in particular to a switching device with an automatic reclosing function, and belongs to the technical field of power distribution. Background technique [0002] In recent years, the wireless communication industry has developed vigorously, and the number of mobile phone users in China has reached hundreds of millions. With the rapid development of wireless communication services, it is necessary to build a large number of outdoor wireless base stations. There are a large number of these outdoor base stations, they are widely distributed, and the working environment is relatively poor, and most of them are installed on the top floors of ordinary residential buildings or in the suburbs, unattended. In the daily work process, the molded case circuit breaker (MCCB) and leakage protection switch are often tripped due to excessive production and domestic electricity consumption or the influence of the working en...

AI Technical Summary

Problems solved by technology

After the circuit breaker trips, it still cannot perform automatic reclosing

And there are some coordination problems between the circuit breaker and the leakage protection switch

In addition, in the base station, multiple low-voltage electrical components such as circuit breakers, automatic reclosing switches, and contactors are required to form the power distribution system, which also causes unreliability.
