Abstract

The invention relates to an automatic switching system of high-voltage distribution wires; therefore, information can be received and sent by wireless communication networks without limitation of a communication distance so long as in a service area, so that monitoring control on states of distribution wires can be carried out in a large range. The provided automatic switching system comprises: a circuit breaker control device, which has a wireless communication function; the required number of circuit breakers (A, B), which are connected with the circuit breaker control device; section control devices, which have a wireless communication function; the required number of switches (A1, A2, B1, and B2), which are connected with the section control devices; a cooperation control device, which has a wireless communication function; a switch L, which is connected with the cooperation control device; and a communication terminal. Software is preserved in all control units of the circuit breaker control device, the section control devices and the cooperation control device; and on the basis of information receiving and sending and cutting off of a fault section and switching of an undamaged section based on the information, the software carries out power transmission on undamaged section with power failure except the fault section, wherein the information receiving and sending are carried out by communication of wireless communication networks among the devices and between the devices and the communication terminal.

Description

technical field [0001] The present invention relates to an automatic exchange system for high-voltage power distribution lines, and specifically relates to an automatic exchange system using mutual communication when cutting off a faulty section of a high-voltage distribution line and performing automatic exchange to a healthy section after the faulty section. In the exchange system, the intercommunication is performed via a wireless communication network installed between the control devices of the utility poles of the high-voltage power distribution line. Background technique [0002] figure 1 A configuration example of a conventional time-limit forwarding system for distribution lines is shown. [0003] exist figure 1 Among them, the switches A1, A2, B1, and B2 are called section switches. The purpose of setting them is to divide the distribution line into multiple sections so that the fault (the fault in the present invention refers to the overcurrent caused by short-c...
