Background technology
The high-voltage electrical apparatus contacts such as underground cable ditch inner high voltage cable splice are in During Process of Long-term Operation, can be because wearing out or contact resistance is excessive generates heat, affect the use of cable when cable temperature is too high, can produce safety in production simultaneously dangerous, usually the temperature of these heating positions can't be monitored, finally cause thus accident to occur, cause fire and large-area power outage, solving high-tension cable contact problems of excessive heat is to stop the key that this type of accident occurs, and realize that on-line temperature monitoring is the important means that guarantees the high-tension cable safe operation, existing on-line monitoring technique can not accurately be judged for the trend of cable duct inner high voltage cable temperature, easily produces erroneous judgement.
Summary of the invention
The utility model exists installation complexity, wire transmission mode to cause the problems such as apparatus insulated performance reduction in order to solve existing high-tension cable temperature monitoring equipment, and a kind of contactless high-tension cable temperature measurement on-line device based on wireless transmission is provided.
The utility model is to adopt following technical scheme to realize: wireless transmission high-tension cable temperature measurement on-line device, comprise passive wireless temperature sensor, the wireless temperature acquisition machine of communicating by letter with described passive wireless temperature sensor, be installed on the thermometric main control terminal of transformer station's master-control room, thermometric main control terminal band LCD display, RS485 interface, IEC61850 Communication Protocol Implementation Interface, ModBus Communication Protocol Implementation Interface arrange monitoring host computer at far-end.
When wireless temperature acquisition machine receives the collecting temperature instruction of host computer, wireless temperature acquisition machine emission thermometric is inquired after radiofrequency signal to passive wireless temperature sensor, the Non-contact passive radio temperature sensor gathers the temperature at contact in the high-tension cable or bus place, carry out non-linear temperature compensation in lower data that receive of the support of adapting software, and will collect temperature signal and be transferred to wireless temperature acquisition machine, wireless temperature acquisition machine is converted into temperature value with temperature signal, and this temperature value sent to the thermometric main control terminal that is installed in transformer station's master-control room, the thermometric main control terminal is to all high-tension cable monitoring temperature informations in the transformer station, store and management, the thermometric main control terminal both can be carried out by LCD display this locality demonstration of temperature information, also can communicate by letter with monitoring host computer by RS485 interface or IEC61850 Standards Code interface or ModBus Standards Code interface, realize the remote online monitoring temperature, analyze and early warning; Monitoring host computer is by the functions such as Remote Acquisitioning, comprehensive inquiry analysis and temperature prediction alarm of high-tension cable temperature monitoring system application software realization to each temperature sensor, the setting of temperature monitoring parameters, temperature information.
Compared with prior art, the utility model adopts the Non-contact passive radio temperature sensor, directly do not contact with contact, bus in the testee high-tension cable, thereby have excellent insulating property, high pressure in can the isolated high-voltage cable, but Measurement accuracy high-tension cable contact temperature is realized high-tension cable contact temperature on-line monitoring; The passive wireless temperature sensor volume little and and wireless temperature acquisition machine between data wireless transmission, easy for installation flexible, be not subjected to high-tension cable structure and spacial influence, passive wireless temperature sensor is the SAW sensor, the SAW sensor adopts passive induction mode, need not battery-operated, reduced the maintenance cost that battery altering brings, the environmental factors such as while dust accretions can not exert an influence to SAW sensor thermometric, the simultaneous temperature sensor has just compensated the deviation in the sensor production process afterwards by the correction of adapting software, sensor can the temperature in any operating temperature range be debugged, not affected by seasonal factor, generally, sensor is only being installed post debugging once, and keeps not needing for many years to proofread and correct again; High-tension cable temperature monitoring system application software realizes the functions such as Remote Acquisitioning, comprehensive inquiry analysis and temperature prediction alarm to each temperature sensor equipment, the setting of temperature monitoring parameters, temperature information.
The utility model is rational in infrastructure, simple, and thermometric is effective, and the interference of anti-highfield, high-intensity magnetic field can not affect the insulating property of high-tension cable.
