Description
Technical field
The present invention relates to a kind of detection device, particularly relate to a kind of leak detecting device.
Background technology
Oil tank of transformer, after the use of long period, inevitably there will be surface damage, and the blind crack that this surface damage brings will cause oil tank of transformer to leak.It is inconspicuous that this blind crack is typically naked eyes, and after leaking, the bulk zone near leakage point will be covered with greasy dirt, and it is extremely difficult that this makes to find out leakage point by naked eyes.
In order to find out the leakage point of oil tank of transformer, it usually needs after oil tank of transformer disassembly, cleaning are completed, relend and help the amplification instrument of specialty oil tank of transformer surface to be scanned, just the position of leakage point so can accurately be determined.Whole process is the most loaded down with trivial details, wastes time and energy.
Summary of the invention
The purpose of the present invention is i.e. to overcome the deficiencies in the prior art, it is provided that a kind of without dismantling the oil tank of transformer leak detector that the leak source position of oil tank of transformer can be detected by oil tank of transformer.
The purpose of the present invention is achieved through the following technical solutions:
Oil tank of transformer leak detector, including: sucker；The conveying pipe that upper end connects with sucker, conveying pipe is made up of transparent plastic；Liquid storage cartridge, liquid storage cartridge connects with the rear end of conveying pipe, and liquid storage cartridge is made up of transparent plastic；Wherein, the rear end of conveying pipe is run through the top of liquid storage cartridge and extends to the bottom of liquid storage cartridge；Wherein, conveying pipe is positioned on the tube wall of the part within liquid storage cartridge and is provided with cavity, and the top of cavity offers the duct with ft connection, and cavity internal memory contains acid-base indicator.
The present invention operationally, by a bit on oil tank of transformer of sucker suction, is doubtful leakage point at this point.If at this point being really leakage point, the transformer oil so leaked at this enters in liquid storage cartridge by conveying pipe, along with the liquid level of the transformer oil in liquid storage cartridge gradually rises, in transformer oil passing hole channel enters cavity and contact with acid-base indicator, owing to transformer oil is acid, acid-base indicator variable color.According to the color of acid-base indicator, staff can confirm whether the point of sucker suction is leakage point intuitively.If in the long period that sucker is after adsorbing this point, acid-base indicator does not has variable color, then may determine that this point is not leakage point, and sucker suction other doubtful leakage point near this point then can be detected by staff.
Further, the arm A connected with the top of described liquid storage cartridge is also included；Also include the flexiplast ball connected with the end of described arm A.
By extruding flexiplast ball, it is possible to be drawn in flexiplast ball by the gas in liquid storage cartridge, keep negative pressure in making liquid storage cartridge such that it is able to make the transformer oil spilt at leakage point enter faster in liquid storage cartridge, shorten the detection time.
Further, the arm B being arranged on described arm A, the check valve B being arranged on arm B, the check valve A being arranged on arm A are also included；Check valve A is between described liquid storage cartridge and arm B, and check valve A is configured to make the gas in described liquid storage cartridge enter described flexiplast ball；Check valve B is configured to make outside the gas exhaust outlet B in described flexiplast ball.
Extruding flexiplast ball, the gas in flexiplast ball is discharged by check valve B, unclamps flexiplast ball, and the gas in liquid storage cartridge is inhaled in flexiplast ball by check valve A.The most repeatedly, negative pressure can be evacuated to by liquid storage cartridge.
Further, the top of described liquid storage cartridge offers up big and down small conical through-hole；Also include taper plug, taper plug offers manhole；Described conveying pipe runs through manhole, and taper plug embeds in conical through-hole.
Taper plug is after inserting in conical through-hole, and conical through-hole extruding taper plug makes taper plug deform, so that the inwall of manhole is close to carry tube outer surface, to realize sealing, prevents foreign material from entering liquid storage cartridge impacting testing result.
Further, the draw ring being connected with described taper plug top is also included.
By draw ring, easily taper plug can be extracted conical through-hole, thus conveying pipe be taken out from liquid storage cartridge, so that acid-base indicator is replaced.
Further, also include the sheet metal of patch and described cavity inner wall surrounding, sheet metal offers at least one observation port.
Owing to conveying pipe entirety is made up of transparent plastic, after being pumped into negative pressure in liquid storage cartridge, the part that conveying pipe may be caused to be positioned within liquid storage cartridge is deformed so that the acid-base indicator in cavity overflows.In order to avoid above-mentioned situation, sheet metal is set in cavity, increases the structural strength of cavity, prevent Wall deformation.Meanwhile, sheet metal is offered observation port, in order to staff observes the color of acid-base indicator.
In sum, advantages of the present invention and having the beneficial effects that:
1. pass through the present invention, it is not necessary to the leakage point of oil tank of transformer can be detected by dismounting oil tank of transformer；
2., by the present invention, according to the color of acid-base indicator, staff can confirm whether the point of sucker suction is leakage point intuitively, easy to use intuitively；
3. flexiplast ball is set, by extruding flexiplast ball, it is possible to be drawn in flexiplast ball by the gas in liquid storage cartridge, in making liquid storage cartridge, keep negative pressure, it is thus possible to make the transformer oil spilt at leakage point enter faster in liquid storage cartridge, shorten the detection time；
4. arm B, check valve A and check valve B are set, by extruding flexiplast ball, it is possible to relatively reliable is evacuated to negative pressure by liquid storage cartridge；
5., by taper plug and conical through-hole, it is achieved seal, prevent foreign material from entering liquid storage cartridge, testing result being impacted；
6. draw ring is set, by draw ring, easily taper plug can be extracted conical through-hole, thus conveying pipe be taken out from liquid storage cartridge, so that acid-base indicator is replaced；
7. sheet metal is set in cavity, increases the structural strength of cavity, prevent Wall deformation, meanwhile, sheet metal is offered observation port, in order to staff observes the color of acid-base indicator.
