Abstract

The invention discloses a cold-standby switching system for remotely-controlled parallel power supply panels. The cold-standby switching system for the remotely-controlled parallel power supply panels comprises the first power supply panel, the second power supply panel, a computer monitoring center and a switching panel, wherein the first power supply panel is used as a working power supply panel, processes supplied power of an external power grid and outputs the supplied power to the switching panel; the second power supply panel is used as the working power supply panel when the first power supply panel breaks down, processes supplied power of the external power grid and outputs the supplied power to the switching panel; the computer monitoring center is used for monitoring the working power supply panel in real time and switching the first power supply panel to the second power supply panel through remote control when the first power supply panel breaks down; the switching panel is used for isolating alternating current parallel output of the first power supply panel and the second power supply panel, transmitting the alternating current parallel output of the first power supply panel and the second power supply panel to a load and meanwhile transmitting direct current parallel output of the first power supply panel and the second power supply panel to the load. According to the cold-standby switching system for the remotely-controlled parallel power supply panels, the alternating current parallel output between the first power supply panel and the second power supply panel can be achieved, so that output of the power supply panels is continuous in the switching process, and therefore operation of the load is not influenced.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a remote control parallel power panel cold standby switching system. Background technique [0002] With the development of railways, a large number of express routes are continuously being built. Correspondingly, the reliability and stability of the power panel for the safety of trains are getting higher and higher. In addition, when the working power panel fails, the cold backup switch of the power panel is carried out. During the switching process, it is also very important to ensure that the output of the power panel is not interrupted. [0003] figure 1 It is a schematic diagram of a power panel remote cold standby switching system according to the prior art. The remote control and cold standby switching system of the power panel drives the input switch and output switch of the power panel through the electric operating mechanism, so as to control the input and removal ...
