Abstract
The utility model discloses a thermometer with a full-range temperature compensation function for an oil surface and a winding of transformer. The thermometer is provided with an elastic element (1) and a compensation element (3). A connecting rod (2) is arranged between the elastic element (1) and the compensation element (3). A temperature sensing conduit (6) is connected with the elastic element (1), and the other end of the temperature sensing conduit (6) is connected with a temperature sensing component (5). A compensation temperature sensing conduit (7) is connected between the compensation element (3) and the temperature sensing component (5). Ambient temperature from a temperature measuring point to the elastic element is compensated in full range. Temperature measurement values of the winding and the oil surface of the transformer approach to actual temperature values. The utility model avoids adverse effects on production works from relatively large temperature differences created by environmental temperature influence.
Description
Technical field:
The utility model relates to a kind of instrument that Transformer Winding, pasta temperature are measured, especially a kind of transformer pasta, winding temperature gage with gamut temperature compensation function.
Background technology:
Known transformer pasta, winding temperature gage all have the flexible member that is used to drive the movement rotation, and flexible member joins by temperature sensing conduit (kapillary) and temperature sensing part (thermometer bulb).Action principle is to reach the temperature sensing conduit after temperature sensing part records Transformer Winding, pasta temperature, and the temperature sensing medium in the temperature sensing conduit will make in the flexible member and expand, and drives the movement action, shows Transformer Winding, pasta temperature thereby drive pointer.Because factors such as environment temperature can influence the accuracy of Transformer Winding, pasta measured temperature, for this reason, also be provided with compensating element, in the existing instrument, between compensating element, and the flexible member connecting link is arranged.It is present that flexible member adopted is convolute elastic tube, in the table body, be provided with bimetallic strip element by way of compensation, stretch on after the bimetallic strip induced environment temperature or under contract, again by connecting link drive contract under the flexible member or on stretch the influence that Transformer Winding, pasta actual temperature value is caused with the compensate for ambient temperature.This kind compensation way is merely able to local ambient temperature in the compensation meter, and can't the temperature of the gamut transmission course of temperature sensing conduit (kapillary) be compensated, to such an extent as between the measurement temperature of Transformer Winding and the actual temperature bigger difference is arranged still.Simultaneously, the convolute elastic tube that adopted of existing transformer pasta, winding temperature gage also has shortcomings such as expulsive force is little, anti-fatigue ability difference.
Summary of the invention:
The utility model is in order to solve existing in prior technology Transformer Winding measured value inaccurate technical matters affected by environment, a kind of transformer pasta, winding temperature gage with gamut temperature compensation function that can accurately show Transformer Winding, pasta actual temperature value to be provided.
Technical solution of the present utility model is: transformer pasta, winding temperature gage with gamut temperature compensation function, be provided with flexible member 1 and compensating element, 3, between flexible member 1 and the compensating element, 3 connecting link 2 is arranged, be connected to temperature sensing conduit 6 with flexible member 1, the other end of temperature sensing conduit 6 and temperature sensing part 5 are joined, and between compensating element, 3 and temperature sensing part 5 compensation temperature sensing catheter 7 are arranged.
Described flexible member 1 and compensating element, 3 are corrugated tube.
Described connecting link 2 is " factory " type.
Different is to be connected to the compensation temperature sensing catheter isometric substantially with the temperature sensing conduit between compensating element, and temperature sensing part to the utility model with prior art, can be to from temperature point, environment temperature between flexible member is carried out the gamut compensation, make the measured temperature of Transformer Winding, pasta more level off to actual temperature value, avoid because the big temperature difference that influence produced of environment temperature is brought adverse effect to production work.Advantages such as the corrugated tube that flexible member, compensating element, adopted has good springiness, the environment temperature adaptive faculty is strong, expulsive force is big, assembly technology is simple, fatigue performance is good; " factory " type connecting link is to utilize lever principle, can participate in interlock under the effect of very little power, and is highly sensitive.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1, have elastic component 1 and compensating element, 3 among the utility model embodiment, between flexible member 1 and the compensating element, 3 connecting link 2 is arranged, and connecting link 2 is preferably " factory " type, flexibly connect by screw, nut and flexible member 1 and compensating element, 3, the central movable of " factory " template is connected on the rotating shaft plate 8.Be connected to temperature sensing conduit 6 with flexible member 1, the other end of temperature sensing conduit 6 and temperature sensing part 5 are joined, temperature sensing conduit 6 places the flexible metal conduit 4 that is fixed between watchcase and the temperature sensing part, between compensating element, 3 and temperature sensing part 5, be connected to compensation temperature sensing catheter 7, compensation temperature sensing catheter 7 is and temperature sensing conduit 6 specifications, kapillary that material is identical, its length and temperature sensing conduit 6 are equal to substantially, also place flexible metal conduit 4.Described flexible member 1 and compensating element, 3 are preferably corrugated tube.
Course of action:
Temperature sensing part 5 is inserted respectively in transformer pasta, the winding measured hole, and the temperature sensing medium in the temperature-driven temperature sensing conduit 6 of temperature sensing part 5 inductions arrives and makes flexible member 1 expansion in the flexible member 1, and then drives movement, pointer etc.Temperature sensing medium in the compensation temperature sensing catheter 7 compensating element, 3 is protracted or after contract, contract or protract after making flexible member 1 by connecting link 2, (being expressed as shift to right or left among the figure) with the acting force of compensation gamut temperature to flexible member 1, makes shown Transformer Winding temperature more accurate.
