Abstract

The invention discloses a method and a system for controlling actions of a contactor applied to a UPS and a UPS. The method comprises: determining a target operating state of an uninterruptible powersupply UPS; and correspondingly controlling opening or closing of a controllable switch and correspondingly controlling power output of a contactor power supply according to the target operating stateof the UPS, in order to cause the UPS to enter the target operating state. It can be appreciated that the application uses a dual control mode of the contactor power supply and the controllable switch to control the contactor, wherein false triggering of any control variable will not cause false closing of the contactor, thereby improving reliability and safety of control.

Description

technical field [0001] The invention relates to the technical field of UPS, in particular to a contactor action control method, system and UPS applied to the UPS. Background technique [0002] With the development of information technology, in the production work of banking, securities, telecommunications, data centers, transportation and medical industries, any power failure may cause irreparable losses to the country, enterprises and even individuals. Based on this, UPS (Uninterruptible Power System, uninterruptible power supply) has been applied more and more. [0003] The UPS includes a main power circuit and a bypass, wherein the switch that controls the on-off of the main power circuit usually adopts a contactor. Since the DC bus in the UPS often uses a large capacitor to ensure the dynamic performance of the output, if the contactor is mistakenly pulled in when the UPS is turned on, the large capacitor will bring a huge current, which will cause the fuse and the main...
