Background technology
In recent years, along with the continuous progress of Substation Automation System, a lot of transformer station has realized unattended or on duty.The visual plant such as high-tension switch cabinet, busbar joint, outdoor chopper switch of transformer station is in During Process of Long-term Operation, the positions such as the contact of switch and bus connection are because of aging or contact resistance is excessive and generate heat, temperature rise exceeds standard, the direct safe and stable operation affecting equipment, and problems of excessive heat is the process of a development, if do not controlled, degree of superheat can constantly aggravation, and to the performance of insulating part and have a huge impact equipment life, finally causes accident to occur.In recent years, there is a lot of power cable and equipment causes fire because of overheated in transformer station, caused large-area cable scaling loss and device damage and by forced-stopping machine, cannot resume production in the short time, thus causing heavy economic losses.Solving device of overheating of electrical problem is stop the key of this type of accident generation, and realizing on-line temperature monitoring early warning is the important means ensureing high voltage electric equipment safe operation.
The domestic temperature detection to high voltage electric equipment mainly contains following several method at present:
1. conventional temperature-measurement mode
The conventional thermometric mode such as thermopair, thermal resistance, semiconductor surface acoustic wave sensor, need plain conductor signal transmission, insulating property can not ensure.
2. optical fiber temperature-measurement
Optical fiber surface acoustic wave sensor adopts fiber optic transmission temperature signal, and light transmitting fiber has excellent insulating property, can high pressure in isolating switch cabinet, can the running temperature of Measurement accuracy high-voltage contact, realizes the on-line monitoring of switch cubicle contact running temperature.But optical fiber has easy to break, the characteristic such as easily broken, non-refractory.Easily cause optical fiber creeping discharge after accumulation dust thus insulativity is reduced, and affecting by switch cabinet structure, the difficulty that connects up in cabinet is larger.In addition, the cost of optical fiber temperature-measurement is also relatively high.
3. infrared measurement of temperature
Infrared measurement of temperature is contactless temperature-measuring, is subject to environment and the interference of electromagnetic field around.Infrared temperature probe must keep certain distance with testee, and just to the surface of testee, requires that measured some nothing in the visual field is covered, be difficult to find suitable installation site in therefore limited in equipment space.Infrared measurement of temperature is easily subject to the factor impacts such as the dust in environment temperature, humidity, air, and temperature measurement error is larger.
Summary of the invention
The object of the invention is overcome the deficiencies in the prior art and provide a kind of structure simple, convenient and practical, safe and reliable, the high voltage electric equipment monitoring-temperature alarm system based on ZigBee technology of good environmental adaptability.This system adopts two kinds of communication modes, and measurement result is reliable, can Timeliness coverage temperature anomaly notify maintainer, thus makes maintainer can Timeliness coverage treatment temperature is abnormal, ensures power grid operation.
For achieving the above object, the present invention is achieved through the following technical solutions:
Based on the high voltage electric equipment monitoring-temperature alarm system of ZigBee technology, described wireless temperature-measuring sensor is arranged on object under test surface, data acquisition/wireless transmitter module comprises data acquisition submodule and wireless data transmission submodule, and wireless temperature-measuring sensor is communicated by ZigBee wireless communication and data acquisition/wireless transmitter module; Described data acquisition/wireless transmitter module is communicated by Ethernet and background monitoring server, and background monitoring server is connected with control flow; Described data acquisition/wireless transmitter module is communicated by ZigBee wireless network and wireless receiving module, and wireless receiving module is communicated with mobile terminal by gsm module; Described mobile terminal is mobile phone.
The invention has the beneficial effects as follows: compared to prior art, wireless high-voltage electrical equipment temperature monitor and alarm system of the present invention utilizes radio network technique to achieve monitoring and the warning of unattended operation transformer station high voltage electric equipment temperature, this system adopts two kinds of communication modes, measurement result is reliable, can Timeliness coverage temperature anomaly notify maintainer, thus make maintainer can Timeliness coverage treatment temperature abnormal, ensure power grid operation.
