Utility model content
The purpose of this utility model is exactly to be based on split to provide one kind the defects of overcoming above-mentioned prior art to exist The transformer Cooling simulation test device of arrangement formula.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of transformer Cooling simulation test device based on split arrangement formula, the device include transformer and Separated radiating Device, described transformer side wall are provided with oil inlet and oil-out, and described oil inlet is connected by pipeline respectively with oil-out Separated radiating device, described pipeline are telescopic elastic pipeline.
Described oil inlet and oil-out are located on same vertical axis, and oil-feed open height is higher than fuel-displaced open height.
Described oil inlet and oil-out is mounted on flow control valve.
Described flow control valve is electrically operated valve, and described electrically operated valve is connected to controller.
Described controller includes single-chip microcomputer or DSP.
Compared with prior art, the utility model has the following advantages that:
(1) the utility model simulation test device sets oil inlet and oil-out conveniently to connect split and dissipate in transformer side wall Hot device, while the pipeline that Separated radiating device connects with transformer uses telescopic elastic pipeline, the convenient length for adjusting oil line pipe Degree, it is also convenient for adjusting the horizontal and vertical position of Separated radiating device, it is convenient to carry out split transformer different height or Separated radiating The contrast of cooling effect of the device under transformer different distance, solve large-scale power transformer split cooling device and dispatch from the factory examination The problem that can not carry out is tested, simulation reckoning is carried out by simulation test device, while horizontal and vertical arrangement split can be verified The difference of radiator effect, the acquisition that the test run data of transformer are cooled down for split provide new solution;
(2) the flow control valve that the utility model oil inlet and oil-out are respectively mounted can be adjusted by controller, from And to carrying out simulated test under different radiating conditions, it is easy to operate, it is fast and reliable.
Brief description of the drawings
Fig. 1 is the structural representation for the transformer Cooling simulation test device that formula is arranged based on split.
In figure, 1 is transformer, and 2 be Separated radiating device, and 3 be oil inlet, and 4 be oil-out, and 5 be flow control valve, and 6 be pipeline.
Embodiment
Embodiment of the present utility model is elaborated below, the present embodiment using technical solutions of the utility model before Put and implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited In following embodiments.
Embodiment
As shown in figure 1, a kind of transformer Cooling simulation test device based on split arrangement formula, the device include transformer 1 and Separated radiating device 2, the side wall of transformer 1 be provided with oil inlet 3 and oil-out 4, oil inlet 3 and oil-out 4 pass through pipeline respectively 6 connection Separated radiating devices 2, pipeline 6 is telescopic elastic pipeline.By stretching telescopic elastic pipeline or the telescopic elasticity of extruding Pipeline realizes the length for changing oil line pipe, and the adjustment of the horizontal and vertical position of Separated radiating device 2 is carried out in convenient experiment, with up to To the contrast of the cooling effect of the different height of Separated radiating device 2 or Separated radiating device 2 under the different distance of transformer 1.
Oil inlet 3 and oil-out 4 are located on same vertical axis, and the height of oil inlet 3 is higher than the height of oil-out 4.Oil-feed Mouth 3 and oil storage mouth correspond to upper box lid and the lower case lid close to transformer 1 respectively.Oil inlet 3 and oil-out 4 are mounted on flow control valve Door 5.Flow control valve 5 is electrically operated valve, and electrically operated valve is connected to controller, and controller includes single-chip microcomputer or DSP, the present embodiment It is middle to use single-chip microcomputer.
Utility model works principle:The simulation test device connects Separated radiating device 2, adjustment point first at the trial The position of body radiator 2, the heating of transformer 1 is realized using the temperature rise short-circuit test method of transformer 1, then measuring transformer 1 And the temperature survey at 2 each position of Separated radiating device.Measurement data during experiment specifically includes:The distance of Separated radiating device 2 The horizontal range of transformer 1, the vertical height of Separated radiating device 2, the tubing length of Separated radiating device 2, the top-oil temperature of transformer 1, enter The temperature of hydraulic fluid port 3 and the temperature of oil-out 4 etc..
