At high-tension electricity gas contacts such as electric system medium and high voltage cable feeder pillar joints in the long-time running process, can be because wearing out or contact resistance is excessive generates heat, influence the use of cable when cable temperature is too high, can produce dangerous simultaneously to safety in production, usually the temperature of these heating positions can't be monitored, finally cause accident to take place thus, cause fire and large-area power outage, solving high voltage cable branch box contact problems of excessive heat is to stop the key that this type of accident takes place, and realize that on-line temperature monitoring is the important means that guarantees the high voltage cable branch box safe operation, existing on-line monitoring technique can not accurately be judged for the trend of high voltage cable branch box temperature, easily produces erroneous judgement.
Summary of the invention
The utility model exists installation complexity, wire transmission mode to cause problems such as apparatus insulated performance reduction in order to solve existing high voltage cable branch box temperature monitoring equipment, and a kind of contactless high voltage cable branch box 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 voltage cable branch box temperature measurement on-line device, comprise the passive and wireless temperature sensor, the wireless temperature collector of communicating by letter with described passive and 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 the wireless temperature collector receives the collecting temperature instruction of host computer, wireless temperature collector emission thermometric is inquired after radiofrequency signal to the passive and wireless temperature sensor, contactless passive and wireless temperature sensor is gathered the temperature at contact in the high voltage cable branch box or bus place, carry out non-linear temperature compensation in following data that receive of the support of adapting software, and will collect temperature signal and be transferred to the wireless temperature collector, the wireless temperature collector 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 gathered all high voltage cable branch box monitoring temperature information in the transformer station, storage and management, the thermometric main control terminal both can be carried out this locality demonstration of temperature information by LCD display, 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 by high voltage cable branch box temperature monitoring system application software realize to each temperature sensor, the setting of temperature monitoring parameters, temperature information long-range obtain, functions such as comprehensive inquiry analysis and temperature prediction alarm.
Compared with prior art, the utility model adopts contactless passive and wireless temperature sensor, directly do not contact with contact, bus in the testee high voltage cable branch box, thereby have excellent insulating property, high pressure in can the isolated high-voltage cable branch box, can accurately measure the high voltage cable branch box contact temperature, realize high voltage cable branch box contact temperature on-line monitoring; Passive and wireless temperature sensor volume little and and the wireless temperature collector between data wireless transmission, easy for installation flexible, be not subjected to high voltage cable branch box structure and spacial influence, the passive and 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, 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 after by the correction of adapting software, sensor can the temperature in any operating temperature range be debugged, not influenced by seasonal factor, generally, sensor is only being installed post debugging once, and keeps not needing for many years to proofread and correct again; By high voltage cable branch box temperature monitoring system application software, realize to each temperature sensor equipment, the setting of temperature monitoring parameters, temperature information long-range obtain, functions such as comprehensive inquiry analysis and temperature prediction alarm.
The utility model is rational in infrastructure, simple, and thermometric is effective, and the interference of anti-highfield, high-intensity magnetic field can not influence the insulating property of high voltage cable branch box.
