Abstract

The invention, which belongs to the technical field of the remote control, provides an apparatus for power supply switching of remote control equipment. With the apparatus, the fault processing time of the transformer substation can be substantially reduced. The apparatus is composed of a single-chip microcomputer, a first relay, a second relay, a network communication chip, and a temperature collection chip. The structural key points are as follows: a communication port of the single-chip microcomputer is connected with a communication port of the network communication chip. One end of a normally-closed switch of the first relay is connected with a zero line and the other end is connected with a zero line output end. One end of a normally-closed switch of the second relay is connected with a live wire and the other end is connected with a live wire output end. A coil terminal of the first relay is connected with a first control signal output port of the single-chip microcomputer; a coil terminal of the second relay is connected with a second control signal output port of the single-chip microcomputer; and a signal output port of the temperature collection chip is connected with a single input port of the single-chip microcomputer.

Description

technical field [0001] The invention belongs to the technical field of remote control, and in particular relates to a device for switching and switching power of remote control equipment. Background technique [0002] After long-term operation statistics, there are widespread crashes in substation control automation and protection automation equipment, and the frequency of such failures is extremely high, causing serious impacts. However, the troubleshooting method is relatively simple. Restarting the power supply can basically solve 90% of these problems. The substations currently maintained by Shenyang Power Supply Company are widely distributed, and maintenance personnel are in short supply, resulting in a long time to deal with similar faults, which affects system operation safety and operation indicators. Apply automation terminal technology to realize online monitoring of automation system equipment, mainly use the existing network to complete the remote disconnection...
