Abstract
The utility model discloses an on-line nondestructive oil temperature detecting device which is applied to a lighting distribution transformer, and is characterized in that the oil temperature detecting device comprises a temperature probe and a temperature compensating signal processing unit. The temperature probe comprises a magnetic shell and a temperature sensor encapsulated in the magnetic sheet which are used to collect the outer temperature of the transformer, and the temperature compensating signal processing unit comprises an A/D collecting unit, a CPU temperature compensating processor, a communication unit and a memory, wherein the A/D collecting unit makes analog-to-digital conversion to the temperature collected by the temperature probe and supplies the temperature to the CPU temperature compensating processor, and the CPU temperature compensating processor turns the temperature into the oil temperature corresponding to the transformer, compared with the temperature range of the memory, the detecting device gives an alarm through the communication unit when the measured oil temperature of the transformer is more than high/low limit.The on-line nondestructive oil temperature detecting device has the advantages of simple construction, not needing power cut, and not affecting the property of the transformer and the like.
Description
Technical field
The utility model is to be used for the warm pick-up unit of substation transformer oil, especially a kind of oily temperature pick-up unit of online harmless light distribution transformer.
Background technology
By the oil temperature of monitoring substation transformer, can in time find the unusual condition of transformer operation, avoid fault to take place, guarantee electric power netting safe running.But there is the substation transformer that does not possess oily temperature measuring ability in a large number to move at the scene at present, detect modification scheme according to the traditional oils temperature, must be after transformer be stopped transport, oil in the fuel tank is poured out, on fuel tank, open and cut the hole that detection probe is inserted, irritate oil, sealing again, detect the back operation, so transform the influence of wasting time and energy and use, and improved transformer performance may be influenced.
Summary of the invention
Detect the problem of transforming difficulty at the online oil temperature of substation transformer, provide a kind of harmless transformation and full weather to detect, in case the device that unusual circumstance is in time reported to the police to the relevant personnel.
In order to realize the foregoing invention purpose, the utility model provides a kind of online harmless oil temperature pick-up unit, is applied to it is characterized in that on the light distribution transformer, comprising:
One temp probe comprises a magnetic shell and interior encapsulation one temperature sensor thereof, is used to gather the external temperature of described transformer;
The temperature compensation signal processing unit, comprise A/D collecting unit, cpu temperature compensation processor, communication unit, storer, described A/D collecting unit carries out analog to digital conversion with described temp probe collecting temperature, and offer described cpu temperature compensation processor, described cpu temperature compensation processor is answered described temperature inversion the oil temperature of transformer in pairs, by with described storer in temperature range relatively, when the described temperature of oil in transformer that records surpasses upper lower limit value, report to the police by described communication unit.
Reasonable is that described temperature compensation signal processing unit further comprises:
One power supply unit is described cpu temperature compensation processor power supply.
Reasonablely be described sheathing material good heat-transfer and have explosion-proof.
Temperature of oil in transformer pick-up unit of the present utility model detects the perforate transformation with traditional temperature of oil in transformer and compares, and it is simple and easy to have a construction, need not to have a power failure, and does not influence the advantages such as performance of transformer.
Description of drawings
Below, with reference to accompanying drawing, for those skilled in the art that, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.
Fig. 1 is the structured flowchart of the utility model pick-up unit;
Fig. 2 is the structured flowchart of temperature compensation signal processing unit among Fig. 1.
Embodiment
See also shown in Figure 1, oil temperature pick-up unit of the present utility model comprises temperature compensation signal processing unit 10 and temp probe 20 two parts, wherein temp probe 20 is by ferromagnetism, good heat-transfer and shell with explosion-proof performance, and portion encapsulates a temperature sensor and forms within it.During use, this temp probe 20 directly is adsorbed on the outside surface of transformer, and temperature sensor converts the transformer surface temperature that collects to simulating signal and exports to temperature compensation signal processing unit 10.
This temperature compensation signal processing unit 10 comprises A/D collecting unit 101, be used for the transformer surface temperature of collecting temperature sensor acquisition and carry out analog to digital conversion, offer cpu temperature compensation processor (being called for short CPU temperature compensation processor) 103 then, this cpu temperature compensation processor 103 changes into corresponding temperature of oil in transformer with this digital signal processing, by comparing with the temperature range of preservation in the storer 104, when the temperature of oil in transformer that records surpasses upper lower limit value, carry out active by communication unit 105 and report to the police.In addition, power supply unit 102 is 103 power supplies of cpu temperature compensation processor.
Temperature of oil in transformer pick-up unit of the present utility model detects the perforate transformation with traditional temperature of oil in transformer and compares, and it is simple and easy to have a construction, need not to have a power failure, and does not influence the characteristics such as performance of transformer.Therefore adopt this device will shorten transformer and transform the duration, reduce improvement cost significantly, and the risk of avoid constructing dangerous risk and transformer performance variation.
More than all embodiment only for the explanation the utility model usefulness, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, so all technical schemes that are equal to also should belong to category of the present utility model and should be limited by each claim.
