The testing device is characterized by further comprising a funnel, a sample tube, a pressing sleeve, a plug and an oil delivery pipe, wherein the center of the bottom of the funnel is communicated with an oil discharging pipe on the oil tank in a threaded mode through a tubular joint; the sample tube is arranged in the middle of one side of the oil tank, communicated with the inner cavity of the oil tank, and used for arranging test samples; the plug with a cylindrical upper end and a conical lower end is arranged in the tubular joint of the funnel; and the oil delivery pipe is arranged at the bottom of one side of the oil tank and communicated with the inner cavity of the oil tank. The testing device is simple in structure, convenient to use, low in cost and high in accuracy; the testing device filled with test samples and oil is placed in an oven and heated to the set time and temperature, oil is taken out, and the compatibility of solid with insulating oil is tested through an oil color spectrum method; and a good testing condition is provided for selection and usage of materials.
Description
Technical field
The present invention relates to a kind of electrical measuring device, especially the proving installation of solid and insulating oil compatibility.
Background technology
Solid is compatible with insulating oil, and namely under operating mode, the two can not react.Wherein, solid is generally copper, platinum, semiconductor and pottery etc.; Insulating oil refers generally to transformer oil.When carrying out insulating structure design, the compatibility of liquid insulating medium and solid material to be grasped in advance, with reasonable selection, reach designing requirement.At present, the means of testing of solid and insulating oil compatibility has two classes, and namely the practical vacuum equipment in laboratory vacuumizes rear heat aging and mixes aging with on-the-spot not air-isolation.The former cost is too high, and These latter results is forbidden.Equipment aspect is similar, is all oil tank, sample, aging rear sampling and testing.The oil sample oil colours spectrometry of taking-up is measured the size of its air content, and which kind of gas of content, to determine solid and insulating oil compatibility.
Summary of the invention
The object of this invention is to provide a kind of easy, low cost and the high solid of accuracy and insulating oil compatibility test device.
For reaching above-mentioned purpose, technical scheme of the present invention is:
A kind of solid and insulating oil compatibility test device, it comprises oil tank and oil hole thereof, characterized by further comprising:
Center to be threaded the funnel be communicated with by tubular configured joint and flowline on described oil tank below;
Be located at described oil tank one middle side part, and communicate with oil tank inner chamber, for arranging sample pipe and the gland thereof of test specimen;
In described filler tube straight coupling, the conical plug that to be provided with upper end be cylindricality lower end is;
Be located at described oil tank side lower curtate, and the petroleum pipeline communicated with oil tank inner chamber.
Described sample Guan Yuqi gland is that high temperature resistant thread seal connects.
The collar extension of described petroleum pipeline is sealedly connected with collar joint.
One end of described test specimen is truncated cone-shaped, and the other end is cylindrical.
The solid of above structure and insulating oil compatibility test device, be placed on the test specimen of solid in the sample pipe of oil tank one middle side part, and fixing with gland sealing, and after oil filled by oil tank, test specimen is immersed in oil.The effect of funnel is that oil volume expands and overflows oil tank when preventing from expanding with heat and contract with cold, and plug wherein realizes air insulated by the conical contact surface at tip.By the collar joint that petroleum pipeline and collar extension thereof are tightly connected, can conveniently inject or discharge insulating oil.And the installation and removal of test specimen and funnel are also very simple and convenient.Test specimen is equipped with in sealing and fills oily proving installation and put into baking box, after the time being heated to setting and temperature, oil taking-up oil colours spectrometry is measured the size of its air content and the content of gaseous species, and make the different oil dissolved gas of each test condition containing scale and contrast, air content is large, illustrate that the compatibility of solid and insulating oil is bad, otherwise, good.Thus easy, low cost and the high solid measured of accuracy and insulating oil compatibility, the choice and operation for material provides good test condition.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present invention.
Fig. 2 is perspective view of the present invention.
In the drawings, funnel 1, tubular configured joint 2, sample pipe 4 and gland 3 thereof, solid test sample 5, oil tank 6, petroleum pipeline 7, collar joint 8, upper flowline 9, plug 10.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Shown in Fig. 1, it is sectional structure schematic diagram of the present invention.As we know from the figure, oil tank 6 by the upper flowline 9 above it and funnel 1 below in the middle of tubular configured joint 2 be threaded, by two inner space of funnel 1 and oil tank 6.The endoporus top of tubular configured joint 2 is divided into stepped cylindrical shape, and wherein the columniform plug 10 of respective steps, realizes sealed attachment by the combination of both stepped cylindrical shapes.The lower end of plug 10 is conical, and namely the surface of contact of plug and oil tank is conical.At oil tank 6 one middle side part, be provided with and communicate with oil tank 6 inner chamber, for arranging sample pipe 4 and the gland 3 thereof of solid test sample 5; Wherein, sample pipe 4 and oil tank 6 seal and are fixedly connected, and connect with gland 3 screw thread refractory seals, one end of test specimen 5 is truncated cone-shaped, and the other end is cylindrical.Test specimen 5 is located in sample pipe 4, and cylindrical one end is stretched out outside sample pipe 4.At the lower curtate of oil tank 6 side, be provided with the petroleum pipeline 7 communicated with oil tank 6 inner chamber, outside it, be provided with collar joint 8, for testing input or the escape hole of insulating oil.Tubular configured joint 2 also can coordinate with collar joint as the going out of oil tank 6, oil-in.Test specimen 5 is solid material, as: copper, platinum, semiconductor and pottery etc.
This solid with the using method of insulating oil compatibility test device is:
1. oil tank upper funnel 1 is dismantled;
2. solid test sample 5 loads in sample pipe 4, and is fixed with gland 3;
3. from the collar joint 8 injection transformer insulating oil outside petroleum pipeline 7, until be full of the inner chamber of oil tank 6, the port of upper flowline 9 starts bleed, and slight oscillatory eliminates bubble, ensures do not have gas in oil tank;
4. plug 10 is placed on the endoporus of tubular configured joint 2, installation funnel 1 is fixedly connected with upper flowline 9 screw thread;
5. continue oil-filledly to flood plug 10 to pasta in petroleum pipeline 7, realize air insulated, compatibility experiments can be carried out to whole proving installation;
6. after carrying out compatibility experiments, open the funnel 1 of oil tank 6 upper end, insulation oil sample can be extracted from collar joint 8, test with the oil colours spectrometry of prior art, and bear result.Thus measure solid and insulating oil compatibility.
