Description
Technical field
The present invention relates to transformer special test equipment field, specifically a kind of portable transformer oil conservater capsule is airtight
Property detector.
Background technology
With the continuous increase of power network and transmission line of electricity capacity, high-power transformer purposes is more and more wider, in view of oil immersed type
Transformer capacity adaptability is preferable, and installation requirement is relatively low, and overload capacity is stronger, so being obtained in power system relatively broad
Application；Transformer oil bears the effect of insulation and cooling, and quality requirements are higher, do not allow directly to connect with air in operation
Touch, and the phenomenon expanded with shrinkage be present, due to the change of load and environment temperature to ensure that its is normal in the part such as transformer
Expansion and shrinkage, while avoid oil from directly being contacted with the external world, conservator capsule is exactly sharp weapon therein, and it coordinates with respirator, both
Ensure that transformer normally expand, shrinkage（Breathing）, it also avoid oil and directly contacted with the external world, while also can immediate reaction change
Depressor oil level.Its principle is that capsule gas is identical with air by dehydrating breather, and the bottom surface of collapsible bag is close in oil conservater
Pasta on, make there is no air between capsule and pasta, when pasta changes, in the presence of oil pressure and atmospheric pressure, glue
Capsule can expand and shrink therewith, and oil is sent out or absorbed.But we have found that working as conservator capsule in the work of a large amount of site examining and repairings
When situations below be present：1）Mass defect in itself be present in capsule；2）Because misoperation causes capsule to damage in installation process, 3）
Capsule service life is long to there is aging, cracking, and the probability for causing capsule to occur rupturing is high.Its reason one is because capsule product
Zhi Bushi transformer manufacturings factory is completely controllable, and general transformer factory also will not particularly be detected to capsule, at random
Delivered as the annex of transformer；Second, the installation of capsule is not that in transformer factory but at the scene, environment is complicated and right
Installation personnel technology there are certain requirements.If conservator capsule ruptures, the transformer oil in conservator can flow slowly into capsule, when
During transformer temperature rise capsule compression, its internal oil flows out after being extruded along respirator pipeline, so as to pass through breathing
Outside device overflow to transformer；When transformer temperature reduces capsule expansion, atmospheric pressure squeezes into extraneous air in conservator, due to
Air in capsule directly contacts with transformer oil, so as to accelerate the deterioration of transformer oil, and when gas is excessive, makes oil meter
There is false pasta.To solve the above problems, design portable transformer oil conservater capsule air-leakage detector, for Site Detection
Whether capsule intact in conservator, whether function is normal, ensures that the safe and reliable operation of transformer is significant.
The content of the invention
The present invention is in order to solve problems existing for existing transformer detection means, there is provided a kind of portable transformer
Oil conservater capsule air-leakage detector.
The present invention is achieved by the following technical solutions：Portable transformer oil conservater capsule air-leakage detector, bag
Casing is included, the casing includes under casing and case lid, and air accumulator and the oil pressure detection bucket with valve are provided with the under casing,
The gas outlet of the air accumulator is connected in metal tubes by pressure loading valve, and separation valve door and air pressure are provided with metal tubes
Table, the first high pressure resistant flexible pipe stretched out outside under casing is connected with the gas outlet of metal tubes；It is provided with the oil pressure detection bucket
Oil pressure gauge, oil pressure detect the second high pressure resistant flexible pipe for being connected with and being stretched out outside under casing on the oil-out of bucket.
As the further improvement of technical solution of the present invention, the detector also includes the heating being wound in outside air accumulator
Band, the power interface of power supply, and the heater switch of control heating tape work are provided for heating tape.
As the further improvement of technical solution of the present invention, the detector also includes the liquid crystal timing under casing
Device.
As the further improvement of technical solution of the present invention, by being fastened between the under casing and case lid of the casing
Together.
As the further improvement of technical solution of the present invention, anti-skidding mat handle is installed on the under casing.
As the further improvement of technical solution of the present invention, divide on the first high pressure resistant flexible pipe and the second high pressure resistant flexible pipe
The abutted flange being connected with transformer is not installed.
As the further improvement of technical solution of the present invention, the first high pressure resistant flexible pipe and the second high pressure resistant flexible pipe are in
Helical coil.
The present invention solves scene at present and lacks the instrumentation that air-leakage test can be carried out to capsule in installation for transformer
The problem of, its is easy to operate, volume is light and handy, is easy to carry, whether when new equipment is installed or conventional Overhaul site all may be used
Reliably to be tested capsule in conservator, it is ensured that capsule is intact in conservator, function is normal, prevents because capsules break causes transformation
The deterioration of device oil is overflowed, and the situation of false oil level occurs in conservator, it is ensured that transformer safety, stable operation, the device is simultaneously
Worked suitable for capsule air-leakage test in high-voltage shunt reactor conservator.
