Description
[technical field]
The utility model relates to a kind of test casing, particularly a kind of paper condenser test casing.
[background technology]
Sleeve pipe is as high pressure inlet wire and outlet equipment, be used for electric current is introduced or drawn the metal shell of transformer, isolating switch or other equipment, also being used for conductor or bus and passing buildings or wall, play insulation and mechanical support effect, is one of critical component of electric system.
The most Oil-impregnated Paper Condenser Bushing in History that adopt of domestic 110kV and above bushing shell for transformer, it is by conservator, insulator, flange and capacitor core etc. are formed up and down, and existing external insulation has interior insulation again.Externally bear very high electricity, heat and mechanical stress simultaneously under the Can Ku environment, service condition is relatively harsher.In inside, the Electric Field Distribution more complicated, an electrode of sleeve pipe inserts the inside of (or passing) another electrode, is a kind of typical plug in construction, and its electric field is big perpendicular to the component of dielectric surface, and the voltage distributed pole is inhomogeneous surfacewise.Electric field at the spacer flanger edge is very concentrated, causes surperficial gliding spark discharge and flashover easily; Very strong because of the electric field between flange and the contact tube simultaneously, insulating medium punctures easily.Sleeve pipe and other electrical equipment are supporting, and claimed structure compactness and size are little, itself are again the unitized constructions of organic and inorganic, gas, liquid and solid material, under the effect of highfield, and various dielectric property complexity, problems such as shelf depreciation are more outstanding.
The normal operation of sleeve pipe reliability of operation and operation maintenance pair other expensive electrical equipments (as power transformer, isolating switch) supporting with it is very important.If have an accident, transformer can damage because bursting of sleeve pipe afterbody cause its main body, and catching fire, and other oilpaper compound inslation equipment also can set off an explosion combustion-supportingly on every side, causes the networking at equipment place out of service, can cause very huge economic loss.Therefore, the research of phenomenon such as the shelf depreciation that in use takes place for sleeve pipe, puncture and aging rule and life-span management is just very important.But high pressure paper condenser sleeve pipe volume is big, and Heavy Weight is made complexity, and price is high, and the restrictive condition that is subjected to is many, so the laboratory does not mostly possess the condition of the high-voltage capacitance sleeve pipe being carried out accelerated aging test.In a single day ageing research for the high-voltage capacitance sleeve pipe all is based on the sleeve pipe that moves in the electric system mostly at present, but the sleeve pipe ageing process of actual motion is slow, and has an accident, can bring about great losses to electric system.
[utility model content]
For solving above technical matters, the utility model provides a kind of paper condenser test casing.
The utility model adopts following technical scheme:
A kind of paper condenser test casing, comprise left insulator and right insulator, described left insulator is connected by flange with right insulator, in the cavity that left insulator, right insulator and flange form guide rod is installed, and described guide rod is connected on the capacitor core by left bolt and right bolt.
As preferred embodiment of the present utility model, the top of described flange is provided with glass oil window to observe the oil level of insulating oil in the cavity.
As preferred embodiment of the present utility model, further be connected with vacuum pumping valve on the described flange so that cavity is vacuumized.
As preferred embodiment of the present utility model, further be connected with oiling or oil pumping valve on the described flange with to annotating insulating oil in the cavity or taking out insulating oil.
As preferred embodiment of the present utility model, described flange is that detachable is connected with left insulator and right insulator.
As preferred embodiment of the present utility model, described flange links to each other with the outermost layer pole plate of capacitor core.
Compared with prior art, the utlity model has following beneficial effect: the utility model can carry out the accelerated deterioration experiment to Oil-impregnated Paper Condenser Bushing in History under laboratory condition, volume is little, in light weight, simple in structure, low cost, flange, insulator and guide rod are all detachable, and it is namely reusable to change capacitor core.
[description of drawings]
Fig. 1 is the structural representation of the utility model sleeve pipe.
1. flanges among the figure, 2. right insulator, 3. left insulator, 4. guide rod, 5. glass oil window, 6. oiling or oil pumping valve, 7. vacuum pumping valve, 8. left bolt, 9. right bolt.
[embodiment]
See also shown in Figure 1ly, the utility model test casing mainly is made up of flange 1, insulator (being divided into left insulator 3 and right insulator 2), guide rod 4.Flange 1 two ends link to each other with insulator, oiling are installed on the flange 1 or oil pumping valve 6(is used for oiling), vacuum pumping valve 7(is in order to vacuumize) and glass oil window 5(in order to observe oil level), the internal capacitance fuse by bolt by the insulator centre-lock.
Specifically, described flange links to each other with left insulator 3 with right insulator 2 respectively, is wrapped on the guide rod 4 capacitor core and then is fixed on the sleeve pipe center by left bolt 8 and right bolt 9.It is dual-purpose with oil pumping that oiling or oil pumping valve 6 can be done oiling, and as the fuel feeding valve time spent, with the sleeve water placing flat, insulating oil is sprue bushing inside from fuel feeding valve; As the oil pumping valve time spent, sleeve pipe is tilted to place, insulating oil can take out from the oil pumping valve.The effect of vacuum pumping valve 7 is, when capacitor core installs, after inside pipe casing is filled with oil, carries out vacuum pumping.Glass oil window 5 is used for observing oil level, guarantees that capacitor core has been insulated oily thorough impregnation.
Capacitor core at first by bolt to insulator, assemble flange and insulator then, then carry out oiling and vacuumize.Because flange and insulator are all detachable, this test casing can reuse, and only need change capacitor core.
The outermost layer pole plate of capacitor core links to each other with flange 1, during work, adds high pressure flange ground connection by bolt.Be example with 20kv capacity test sleeve pipe, capacitor core is 7 layers of pole plate, then the volume of test casing is about: the wide * height of the long * of 500*110*150(/mm), obviously dwindle than the high-voltage capacitance sleeve pipe volume that moves in the practical power systems, can satisfy under laboratory condition, in baking oven, carry out accelerated aging test.
