Abstract
The utility model discloses an oily formula distribution transformer atmospheric pressure oil leak test device (b), atmospheric pressure adjusting device and manometer set up respectively at the top of leak test jar, and the air intake valve setting is on atmospheric pressure adjusting device's input tube, and the oil circuit valve sets up on the oil circuit pipe, and the one end of oil circuit pipe communicates the bottom of leak test jar, its other end intercommunication transformer tank's top. Compared with the prior art, the utility model, the leak test pressure adjustment is nimble, can satisfy different pressure transformer finished product leak tests, has combined the reliability of oil pressure leak test and the convenience of atmospheric pressure leak test, finds transformer finished product seepage position easily, has guaranteed the reliable of leak test.
Description
Technical field
The utility model relates to transformer technology field, is specifically related to a kind of oil immersion-type distribution transformer finished product leakage testing device.
Background technology
Oil immersion-type distribution transformer finished product leakage test is Transformer Plant Test, and test method checks its sealing by being filled with certain pressure to fuel tank.Leak test adopts air pressure leakage check and oil tank static pressure leak test two kinds of methods usually, oil tank static pressure leak test often adopts at power transformer, and by adjustment oil tank liquid level height control leak test pressure, leak test is reliable and be easy to search breakthrough, shortcoming is complicated operation, not easily adopts during typical products in mass production leak test; Air pressure leakage check often adopts at substation transformer, observe pressure change after being filled with oily loading pressure by adjustment and judge whether seepage, advantage is that method is simply easy to typical products in mass production leak test, shortcoming is as seepage gas not easy-to-search breakthrough when seepage arranged at fuel tank top, and during leak test, transformation oil dissolved gas can increase.
Summary of the invention
For solving prior art Problems existing, the utility model provides a kind of reliable substation transformer leakage testing device easily, and its technical scheme taked is:
This device comprises air intake valve, barometric control unit, tensimeter, oil circuit valve, oil-way pipe and leak test tank, barometric control unit and tensimeter are separately positioned on the top of leak test tank, air intake valve is arranged on the input pipe of barometric control unit, oil circuit valve is arranged on oil-way pipe, one end of oil-way pipe is communicated with the bottom of leak test tank, and its other end is communicated with the top of oil tank of transformer.
Compared with prior art, leak test is easy, reliability is high for the utility model, is convenient to find transformer finished products seepage place; Leak test pressure flexible adjustment, can meet different pressures transformer finished products leak test; Leak test gas not easily incorporates in transformer oil; Leak test can to multiple stage transformer finished products leak test simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, this device comprises air intake valve 1, barometric control unit 2, tensimeter 3, oil circuit valve 4, oil-way pipe 5 and leak test tank 6, barometric control unit 2 and tensimeter 3 are separately positioned on the top of leak test tank 6, air intake valve 1 is arranged on the input pipe 7 of barometric control unit 2, oil circuit valve 4 is arranged on oil-way pipe 5, one end of oil-way pipe 5 is communicated with the bottom of leak test tank 6, and its other end is communicated with the top of oil tank of transformer 8.Leak test tank 6 is pressure vessel, can pressure-bearing 0.2MPa, tensimeter 3 range 0-0.06MPa, and barometric control unit 2 adopts precise pressure-reducing valve, can ensure that Output pressure is accurately stable.
During use, leak test tank 6 is injected qualified transformer oil, oil level is 1/2-2/3 of leak test tank height, opens compressed air inlet valve door 1, makes pressurized air enter barometric control unit 2 from input pipe 7, then adjustable pressure regulating device 2, make tensimeter 3 leak test pressure be transformer finished products leak test pressure, then open oil circuit valve 4, observe tensimeter 3 pressure and whether change, must pressure adjustment assembly be regulated as changed, closing air intake valve 1 as unchanged.Within the leak test time, observe transformer finished products ooze out with or without oil, keep in repair if any leak location need be searched, as nothing then illustrates transformer finished products ne-leakage.
