Abstract
The utility model provides a system for wirelessly monitoring the temperature of a high-voltage switch contact of a high-voltage switch cabinet. The system comprises a wireless sensing system and a remote management master station. The system is characterized by consisting of a plurality of wireless temperature transmitters, a data concentrated display (DI), an upper computer of a monitoring center, a remote terminal unit (RTU) and a communication link. The transmitters are attached to the surface of a bus joint and near to a touch arm of the switch contact, the transmitters transmit temperature data to the DI by means of wireless communication, the DI is arranged on a faceplate of the high-voltage switch cabinet and is used for collecting, processing, storing and displaying the temperature data transmitted from each transmitter and realizing the corresponding alarm control function, and the DI and an upper mechanism of the monitoring center form a distributed monitoring system by a RS485 bus. By adopting a wireless communication technology, the system realizes the wireless data communication between the temperature transmitters and the data concentrated display, preferably solves the problem of high-voltage isolation without changing the physical structure in the switch cabinet, and solves the problems of the short service life and the bad strong electromagnetic interference resistance of the temperature transmitter by adopting the low-power design and the shielding technology.
Description
Technical field
The utility model relates to a kind of high-voltage switch contact temperature wireless monitor system of high-tension switch cabinet.
Technical background
High-tension switch cabinet is the important electric equipment of generating plant and transformer station, and its inside has six groups of dynamic/static contacts and many places busbar joint usually.Because these links are in the duty of high voltage, big electric current for a long time, as long as the contact resistance of contact or joint has small increase, to cause that all contact or joint temperature raise, if in time do not handle, will produce vicious cycle, finally cause burning high-tension switch cabinet, even directly influence the electric system normal power supply and cause enormous economic loss.Therefore, the temperature of contact in the high-tension switch cabinet and joint is monitored in real time, for the safe operation that ensures high-tension switch cabinet, and even the normal operation of electrical network is of great significance.
Under high voltage, big electric current environment, realize that the on-line monitoring of temperature need solve the difficult problem of high pressure isolation and anti-strong electromagnetic.Existing high-voltage switch contact temperature on-line monitoring technique mainly contains multiple:
(1) is coated with on the surface of busbar joint and switch contact that one deck varies with temperature and the material (cured as temperature-sensitive) that changes color roughly determines temperature range by observing its change color.This method accuracy is low, readable poor, can not carry out quantitatively and measurement in real time, method is original and to employee's requirement height.
(2) utilize the Infrared survey instrument, operating personnel's timing hand-held instrument aims at the busbar joint and the high-voltage switch gear contact is measured.The temperature value error of this method between o～200 ℃ is little, accuracy is high, still, still can't accomplish real-time measurement, and price height, optical device use inconvenience in the high pressure occasion.
(3) mode of employing optical fiber, this method specific implementation is divided into two kinds again, a kind of is to adopt fiber-optical grating temperature sensor, another kind is only to utilize the Optical Fiber Transmission temperature signal, the both has utilized advantages such as optical fiber is high pressure resistant, anticorrosive, anti-electromagnetic interference (EMI), the greatest drawback of this technology is that tested high-voltage charged body need be connected by optical fiber with measuring equipment, therefore can not solve the problem of pollution flashover, and the security of this technology is worth discussion strictly speaking.
The utility model adopts wireless communication technology to make between temperature transmitter and the data centralization display and realizes wireless data transmission, can not change switch cubicle internal physical structure, just solve the problem that high pressure is isolated well, adopt low power dissipation design and shield technology to solve the problem of having brought temperature transmitter serviceable life and anti-strong electromagnetic thus simultaneously.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, and a kind of accuracy of detection height is provided, strong interference immunity, and synchronism and good reliability, low energy consumption, working service is a kind of high-voltage switch contact temperature wireless monitor system of high-tension switch cabinet easily.
The purpose of this utility model is achieved in that a kind of high-voltage switch contact temperature wireless monitor system of high-tension switch cabinet, comprise wireless sensing system and telemanagement main website, it is characterized in that: the high-voltage switch contact temperature wireless monitor system of described high-tension switch cabinet by some wireless temperature transmitters, data centralization display DI, Surveillance center's host computer, long-range end auspicious unit R TU, communication link five parts form.Transmitter is attached on busbar joint surface and the contact arm near switch contact, transmitter sends temperature data to DI by communication, DI is installed on the high-voltage switch gear cabinet panel, collect from the temperature data of each transmitter and handle, store, show and realize corresponding alarm control function, all DI become distributed monitoring system by the RS485 bus with the upper structure of Surveillance center.
