Abstract
The utility model aims to disclose a temperate controller, which comprises a pressure type temperature gauge the elastic element of which is a bellows, a capillary tube and a thermal bulb, wherein the thermal bulb is connected with the pressure type temperature gauge via the capillary tube, temperature sensing liquid is filled around the thermal bulb, the capillary tube and the pressure type temperature gauge to form a sealing system, and the control end of the pressure type temperature gauge is connected with a control circuit of a transformer for alarm and control; the thermal bulb is used for measuring the oil temperature in the oil tank of the transformer, when the oil temperature changes, the medium volume in the thermal bulb changes linearly along the oil temperature, the volume increment is transferred via the capillary tube, so the bellows in the pressure type temperature gauge generates a corresponding linear displacement value, the displacement value indicates the temperature to be measured and drives to output signal, so the control of the temperature rise of the transformer is realized, and the purpose of the utility model is achieved.
Description
Technical field
The utility model relates to a kind of temperature controller, and is particularly a kind of in order to observe and to monitor the temperature controller of transformer oil surface temperature.
Background technology
Temperature controller is a kind ofly to utilize temperature sensing liquid to expand with heat and contract with cold and the incompressible principle of liquid and realize the device of automatic regulatory function.When the control temperature raise, the thrust that the temperature sensing liquid expansion produces turned down heating agent, to reduce output temperature; When the control temperature reduced, temperature sensing liquid shrank, and under the effect of resetting means heating agent was opened greatly, with the raising output temperature, thereby controlled temperature is reached and remains in the temperature range that sets.
The safe operation of transformer and serviceable life, largely depend on the safe and reliable of Transformer Winding, and winding temperature makes insulation breakdown above the insulation tolerable temperature, is the one of the main reasons that causes the transformer cisco unity malfunction.
Yet temperature controller of the prior art can only be realized the temperature control function usually, and does not have relevant protection and warning function, has technological deficiency.
Therefore, need a kind of temperature controller especially, solved the problem of above-mentioned existing existence.
The utility model content
The purpose of this utility model is to provide a kind of temperature controller, at the deficiencies in the prior art, when the transformer oil surface temperature surpasses certain setting value, has and reports to the police and the trip(ping) circuit effect, to guarantee the transformer safe operation.
The technical matters that the utility model solved can realize by the following technical solutions:
A kind of temperature controller, it is characterized in that, it comprises that flexible member is pressure type thermometer, kapillary and the thermometer bulb of corrugated tube, described thermometer bulb is connected with described pressure type thermometer by kapillary, be full of temperature sensing liquid and form sealing system between described thermometer bulb, kapillary and the pressure type thermometer, the control loop of the control end connection transformer of described pressure type thermometer is reported to the police and is controlled.
In an embodiment of the present utility model, the control end of described pressure type thermometer is provided with 2 temperature control switches and 4 control linkage ends.
In an embodiment of the present utility model, described kapillary outside is provided with sheath.
Temperature controller of the present utility model, with the oil temperature in the thermometer bulb measuring transformer fuel tank, when oily temperature changes, medium volume in the thermometer bulb is linear change thereupon, dilatation makes the corrugated tube in the pressure-type thermometer produce a corresponding linear displacement by transmission capillaceous, indicate measured temperature and drive output signal by this displacement, reach control, realize the purpose of this utility model the transformer temperature rise.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
