Abstract

A power transmission temperature detection system comprises a temperature sensor and a relative humidity sensor. The temperature sensor and the relative humidity sensor respectively transmit an acquired temperature value and an acquired relative humidity value to a processor; an actual temperature value of electrical equipment can be obtained through the calculation of the processor; and the actual temperature value of the electrical equipment is transmitted to data terminal equipment which displays the actual temperature value of the electrical equipment. According to the power transmission temperature detection system of the utility model which adopts the above technical schemes, an environmental humidity value is adopted as a technical reference value, such that an obtained temperature value of the electrical equipment is very accurate; and further, through detecting an environmental humidity value, and when the humidity value exceeds a set value, alarm signals can be outputted, such that workers can be reminded to turn on ventilation equipment or drying equipment timely, thereby greatly prolonging the service life of the electrical equipment.

Description

The electric power transfer system for detecting temperature
Technical field
The utility model belongs to the electric power detection range, specifically relates to a kind of electric power transfer system for detecting temperature.
Background technology
The electric power transfer detection system, be in the following transformer station of 550kV, 220kV, 10kV and 10kV, equipment and region of interest thereof such as transformer, reactor, isolating switch, disconnector, lightning arrester, turnover line busbar joint, the busbar joint that confluxes, high-tension switch cabinet contact, long-time running tend to because of loaded current reason such as excessive or surface oxidation and cause resistance value to increase to cause that temperature raises.If can not get timely processing the insulating element performance is reduced, cause the transmission facility insulation breakdown, cause that accident takes place, and brings economic loss to the user.In current many transformer stations, the temperature survey of high pressure equipment for power transmission and distribution, what generally adopt is that infrared point temperature meter or infrared imaging thermometer detect, above-mentioned these pick-up unit efficient are low, real-time is poor, testing staff's labour intensity is big, and testing result and testing staff's professional quality have much relations, and the key position of What is more some equipment can't detect, measuring accuracy is subject to disturb, and has defectives such as metrical information can't intuitively show.
The patent No. is 201120176621.7 utility model, and a kind of electric power transfer system for detecting temperature also is provided, but the temperature value that it is only gathered temperature measuring equipment (wet and dry bulb) is as unique technical parameter.And in practice, electrical equipments such as transformer station, transformer, reactor, isolating switch, disconnector, turnover line bus, bus rod, high-tension switch cabinet contact, because environmental impact, can produce certain humidity: on the one hand, the evaporation meeting of steam produces certain influence to temperature detection, so the temperature value that this temperature measuring equipment records and actual temperature are inconsistent; On the other hand, humidity also is disadvantageous greatly to electrical equipment, and this will shorten the serviceable life of electrical equipment.So it is inaccurate that this technical scheme detects the temperature value that obtains.
The utility model content
The purpose of this utility model provides a kind of detected temperatures electric power transfer system for detecting temperature accurately.
For achieving the above object, the utility model is by the following technical solutions:
A kind of electric power transfer system for detecting temperature, it comprises temperature sensor and relative humidity sensor, temperature sensor and relative humidity sensor are sent into collecting temperature value and rh value in the processor respectively, obtain electrical equipment true temperature value through the computing of processor, and this electrical equipment true temperature value is sent into data terminal equipment show.
Processor carries out computing according to the temperature value of gathering and rh value and obtains humidity value, and when this humidity value surpassed predetermined value, the processor output alarm signal was to alarm.
Temperature sensor and relative humidity sensor are sent to integrated data collection wireless communication apparatus with temperature value and the rh value of gathering, and integrated data is gathered wireless communication apparatus and is sent in the processor by 433MHz micropower radiowave.
Adopt the utility model of technique scheme, also as the Technical Reference value, the electrical equipment temperature value that obtains like this is very accurately with the ambient humidity value.In addition, by the testing environment humidity value, and when humidity value exceeded setting value, exportable warning was reminded the staff in time to open ventilation equipment or drying equipment, thereby has been prolonged the serviceable life of electrical equipment greatly.

Fig. 1 is theory diagram of the present utility model.
Embodiment
As scheme shown in the l, a kind of electric power transfer system for detecting temperature, it comprises temperature sensor and relative humidity sensor, temperature sensor and relative humidity sensor are sent into collecting temperature value and rh value in the processor respectively, obtain electrical equipment true temperature value through the computing of processor, and this electrical equipment true temperature value is sent into data terminal equipment show.
Processor carries out computing according to the temperature value of gathering and rh value and obtains humidity value, and when this humidity value surpassed predetermined value, the processor output alarm signal was to alarm.
Temperature sensor and relative humidity sensor are sent to integrated data collection wireless communication apparatus with temperature value and the rh value of gathering, and integrated data is gathered wireless communication apparatus and is sent in the processor by 433MHz micropower radiowave.
The utility model can be widely used in the remote online thermometric of all kinds of transmission facility tie points of transformer station, automatically record and the storing temperature data, automatically contrast with setting value and carry out overtemperature alarm, automatically with data by the radio communication teletransmission to dispatching center on duty, for the substation safety operation provides scientific basis.This system efficiently solves traditional infrared point temperature meter or the infrared imaging thermometer detects existing use cost height, patrols and examines that efficient is low, real-time is poor, labour intensity is big, temperature measurement accuracy is subject to disturb, data intrinsic problem such as teletransmission fast, has also solved the inaccurate problem of prior art measurement temperature.
The above; it only is the preferable embodiment of the utility model; these embodiments all are based on the different implementations under the utility model general idea; and protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
