Vacuum section switch fault pre-warning system for urban and rural power supply line

Abstract

The invention relates to a vacuum section switch fault pre-warning system for an urban and rural power supply line. The vacuum section switch fault pre-warning system for the urban and rural power supply line comprises a state gathering module of a section switch, a fault pre-warning terminal device, a GMS network and a monitoring master station which manages a plurality of fault pre-warning terminal devices in a remote mode. The state gathering module of the section switch comprises a three-phase current mutual inductor, a humidity sensor, a sonic sensor and a divide-shut brake state signal transducer. The fault pre-warning terminal device comprises a signal processing circuit, an analog to digital (A / D) data acquisition module, a control chip, a communication module, a display module, a keyboard module, a power module, a clock module and an alarming module. The monitoring master station comprises a built-in GMS wireless communication module short message receiving terminal, a serial port communication line, an industrial computer server which is connected with the built-in GMS wireless communication module short message receiving terminal through the serial port communication line and a fault display device which is connected with the industrial computer server. The vacuum section switch fault pre-warning system for the urban and rural power supply line can solve the fault pre-warming problem of the vacuum section switch of the power supply line, and power distribution reliability is improved.

Description

[0001] technical field [0002] The invention relates to a GSM network-based fault warning system for vacuum segmental switches of urban and rural power supply lines, which can solve the fault early warning problem of power supply line segmental vacuum switches and improve power supply reliability. Background technique [0003] With the rapid development of the national economy, the structure and layout of rural power grids are becoming more and more complex, the power consumption is constantly increasing, and the requirements for the reliability and quality of power supply are also getting higher and higher. In order to improve the reliability and safety of the operation of urban and rural power grids, it is necessary to install a set of section switches at certain distances on the transmission line. Once a fault occurs, it can be isolated in sections, which is convenient for early detection of faults and maintenance. This can reduce the power outage time, reduce the power...
