Abstract
The utility model discloses a medium filling device of a temperature controller for a transformer, wherein the medium filling device is provided with a frame (1); a medium filling groove (2) is fixed at the upper end of the frame (1); a pipeline (3) is arranged at the lower end of the medium filling groove (2); a flow adjusting valve (4) and a pipeline butt valve (5) are arranged on the pipeline (3); and a vibration table (6) is arranged at the lower end of the frame (1). According to the utility model, mediums are filled in a copper body and an environmental temperature compensation copper body under normal pressure in an automatic flowing manner, so that medium pressures of the two copper bodies are same; due to the vibration table, bubbles generated in the filling system ascend to the medium surface in the medium filling groove; therefore, physical parameters of the filled mediums of the two copper bodies are same; and the accuracy of environmental temperature compensation is ensured; therefore, the measurement precision of the temperature controller is increased.
Description
Technical field
The utility model relates to a kind of transformer temperature controller and uses production equipment, and is especially a kind of simple in structure, can guarantee medium filling consistance, and the transformer that improves the detection degree of accuracy is with temperature controller medium filling device.
Background technology
The transformer temperature controller need detect Transformer Winding and pasta temperature; Primary structure is that the current transformer that joins with the transformer current mutual inductor is arranged; Current transformer output is joined with heating (resistance wire); Heating places in the copper body of inner chamber, at the front end of copper body catch bar is arranged, and rear end and ambient temperature compensation copper body join; The copper intracoelomic cavity communicates with bulb through conduit, in sealing system that bulb, sensing catheter, copper body constitute and ambient temperature compensation copper body, all has been full of temperature sensing medium.During measurement; The temperature that bulb is responded to, heating element all make the volume of temperature sensing medium change thereupon; And the temperature sensing medium volume in the ambient temperature compensation copper body changes with environment temperature, and the temperature sensing medium volume in the copper body of built-in electrical heating elements is compensated.Volume variable after compensation orders about catch bar and produces a corresponding displacement, and driving movement and drive are with the movement one and place the pointer on the dial plate to rotate, and indicate dut temperature, through set temperature control point temperature are controlled simultaneously.Existing copper body and ambient temperature compensation copper body are equipped with inlet and liquid outlet, when filling medium, inlet and liquid outlet are opened, medium is got into from inlet fills, when filling up the copper body after the liquid outlet outflow, with inlet and liquid outlet shutoff.At present, fill for the copper body that medium vacuumizes and pressurization fills two kinds of methods, vacuumizing method causes easily and retains bubble phenomenon in component wear and the copper body; And pressurization fills the pressure that causes two copper bodies easily and does not wait.Promptly existing methods for filling is difficult to guarantee the consistance of copper body and the filling of ambient temperature compensation copper in-vivo medium; And then influence effect temperature compensation and influence the measuring accuracy of instrument, the transformer temperature controller precision is low to become that people thirst for solving always but the technical barrier of failing all the time to succeed.
Summary of the invention
The utility model is in order to solve the above-mentioned technical matters of existing in prior technology, provide a kind of simple in structure, can guarantee that medium fills consistance, improve detect degree of accuracy transformer with temperature controller medium filling device.
The technical solution of the utility model is: a kind of transformer is with temperature controller medium filling device; Framework is arranged, be fixed with the medium packing groove in the upper end of framework, there is pipeline the lower end of medium packing groove; Flow control valve and pipeline butt joint valve is arranged on the pipeline, be equipped with bumper in the lower end of framework.
The utility model is that the gravity flow mode is filled medium to copper body and ambient temperature compensation copper body under the employing normal pressure; Can make the pressure medium in the two bronze medal bodies identical; The bubble that set bumper then can make in the fill system and produced rises to the dielectric surface in the medium packing groove; Thereby can guarantee that two copper bodies fill the consistance of medium physical parameter, guarantee the accuracy of ambient temperature compensation, thereby improved the measuring accuracy of temperature controller.Though simple in structure, efficiently solve that people thirst for solving always but the technical barrier of failing all the time to succeed.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below with the embodiment of accompanying drawings the utility model.As shown in Figure 1: framework 1 is arranged, be fixed with medium packing groove 2 in the upper end of framework 1, there is pipeline 3 lower end of medium packing groove 2, and flow control valve 4 and pipeline butt joint valve 5 are arranged on the pipeline 3, is equipped with bumper 6 in the lower end of framework 1.
During filling, medium is placed in the medium packing groove 2, the copper body places on the bumper 6, and the inlet on the copper body docks valve 5 and connects with pipeline, the delivery rate of adjustment flow control valve 4 and may command medium.Medium flows out from pipeline 3 under the effect of gravity; The starting shock platform; Be reserved in bubble on the consubstantiality internal chamber wall etc. and can under shock effect, deviate from fully and rise to float on the dielectric surface in the medium packing groove, thereby can guarantee that two copper bodies fill the consistance of medium physical parameter.
