Abstract

Provided is an electric power transmission temperature detection system which comprises a temperature sensor and a relative humidity sensor. The temperature sensor and the relative humidity sensor respectively send the acquired temperature values and relative humidity values to a processor so that an actual temperature value of an electrical device is obtained after operation of the processor, and the actual temperature value of the electrical device is sent to a data terminal device to display. With adoption of the aforementioned technical scheme, the environment humidity value also acts as a technical reference value so that the temperature value of the electrical device obtained in such way is quite accurate. Besides, the environment humidity value is detected, and alarming can be outputted when the humidity value surpasses the preset value so that working personnel is prompted to turn on a ventilation device or a drying device timely, and thus the service life of the electrical device is greatly prolonged.

Description

A kind of power transmission temperature detecting system
Technical field
The invention belongs to electric power detection field, specifically relate to a kind of power transmission temperature detecting system.
Background technology
Electric power transfer detection system, for in the following transformer station of 550kV, 220kV, 10kV and 10kV, equipment and the region of interest thereof such as transformer, reactor, isolating switch, disconnector, lightning arrester, line busbar joint, the bus joint that confluxes, high-tension switch cabinet contact, long-time running tends to because loaded current is excessive or the reason such as surface oxidation causes resistance value to increase to cause that temperature raises.May make insulating element performance reduce if can not get timely processing, cause transmission facility insulation breakdown, cause that accident occurs, and brings economic loss to 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 efficiency are low, real-time is poor, testing staff's labour intensity is large, and testing result and testing staff's professional quality have much relations, and the key position of What is more some equipment cannot detect, measuring accuracy is easily disturbed, and has the defects such as metrical information cannot intuitively show.
The patent No. is 201120176621.7 utility model, and a kind of power transmission temperature detecting system is also provided, but the temperature value that it only gathers temperature measuring equipment (wet and dry bulb) is as unique technical parameter.And in practice, the electrical equipments such as transformer station, transformer, reactor, isolating switch, disconnector, line bus, bus rod, high-tension switch cabinet contact, due to environmental impact, can produce certain humidity: on the one hand, the evaporation meeting of steam produces certain impact to temperature detection, so the temperature value that this temperature measuring equipment records and actual temperature are inconsistent; On the other hand, humidity is also greatly disadvantageous 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 obtaining.
Summary of the invention
The object of this invention is to provide a kind of detected temperatures power transmission temperature detecting system accurately.
For achieving the above object, the present invention is by the following technical solutions:
A kind of power transmission temperature detecting system, it comprises temperature sensor and relative humidity sensor, temperature sensor and relative humidity sensor are sent into collecting temperature value and rh value in 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 and obtains humidity value according to the temperature value gathering and rh value, and in the time that this humidity value exceedes predetermined value, processor output alarm signal is to alarm.
The temperature value of collection and rh value are sent to integrated data collection wireless communication apparatus by temperature sensor and relative humidity sensor, and integrated data gathers wireless communication apparatus and is sent in processor by 433MHz micropower radiowave.
Adopt the present invention of technique scheme, using ambient humidity value, also as Technical Reference value, the electrical equipment temperature value obtaining is like this very accurately.In addition, by testing environment humidity value, and in the time that humidity value exceeds setting value, exportable warning, reminds staff to open in time ventilation equipment or drying equipment, thereby has greatly extended the serviceable life of electrical equipment.
Brief description of the drawings
Fig. 1 is theory diagram of the present invention.
Embodiment
As shown in Figure l, a kind of power transmission temperature detecting system, it comprises temperature sensor and relative humidity sensor, temperature sensor and relative humidity sensor are sent into collecting temperature value and rh value in 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 and obtains humidity value according to the temperature value gathering and rh value, and in the time that this humidity value exceedes predetermined value, processor output alarm signal is to alarm.
The temperature value of collection and rh value are sent to integrated data collection wireless communication apparatus by temperature sensor and relative humidity sensor, and integrated data gathers wireless communication apparatus and is sent in processor by 433MHz micropower radiowave.
The present invention can be widely used in the remote online thermometric of all kinds of transmission facility tie points of transformer station, automatically record and storing temperature data, automatically and setting value contrasts and carry out overtemperature alarm, automatically by data by radio communication teletransmission to dispatching center on duty, for substation safety operation provides scientific basis.This system efficiently solve traditional infrared point temperature meter or infrared imaging thermometer detect existing use cost high, patrol and examine that efficiency is low, real-time is poor, labour intensity is large, temperature measurement accuracy is easily disturbed, the data intrinsic problem such as teletransmission fast, also solved prior art and measured the inaccurate problem of temperature.
The above; it is only preferably embodiment of the present invention; these embodiments are all the different implementations based under general idea of the present invention; and protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
