Embodiment Construction

[0011] figure 1 It is the working principle diagram of UPS. When the mains power is cut off, the staff completes the connection between the UPS input switch Q1 and the mains power, and the UPS output switch Q3 and the load power supply. The switch button on the control panel can realize the rectification unit and inverter unit to provide stable and pure power to the load, and the charging unit can charge the battery pack at the same time. The battery pack switch Q2 is always closed, and only when the battery pack is aging or damaged and needs to be replaced, the battery pack switch Q2 is turned off.

[0012] figure 2 It is a specific embodiment of the present invention. When the UPS works normally, the UPS external bypass main circuit breaker S2 is open, the UPS external bypass input circuit breaker S1, and the UPS external bypass output circuit breaker S3 are closed. When the UPS fails, it automatically switches to the internal bypass state. At this time, the UPS is equiv...

Abstract

The invention discloses a test method for an external bypass of an uninterrupted power supply (UPS) and belongs to the technical field of test. The external bypass is added on the basis of an own line of the UPS, wherein the external bypass consists of a UPS external bypass input breaker S1, a UPS external bypass main breaker S2 and a UPS external bypass output breaker S3. When the UPS operates normally, the external bypass is opened; when the UPS fails, the external bypass is closed, an external network power supply, namely a mains supply, supplies power to production equipment through the external bypass of the UPS, and an operator changes the damaged UPS into a good UPS within a short period; and after the good UPS comes into operation, the external bypass is opened, and the mains supply supplies the power to the production equipment through the UPS so as to guarantee the stable and safe operation of the production equipment. The method has the advantages that: the problem of abnormal operation of the production equipment due to self-damage of the UPS and instable power output is solved.

Description

technical field [0001] The invention belongs to the technical field of testing, and in particular provides a UPS external bypass test method, which adds an external bypass on the basis of the original line of the UPS itself, thereby ensuring the stability of production to the greatest extent. Background technique [0002] At present, various industrial enterprises mostly use commercial power to supply power for production equipment through a relatively large (above 3KVA) uninterruptible power supply, namely UPS. During the production process of the enterprise, if the UPS itself (including components and control units) is damaged, the external power supply, that is, the mains power, will directly supply power to the production equipment through the internal bypass of the UPS. At this time, if the mains power is disturbed or has any fluctuations, it will cause the production equipment to fail to operate normally. Contents of the invention [0003] The purpose of this method...
