Description
The application is to be that June 25, Application No. 201310258536.9, invention and created name in 2013 are the applying date
The divisional application of the application for a patent for invention of " the unimpeded test device of moisture absorber of transformer ".
Technical field
The present invention relates to the operational test set of the attached safety guard of transformator is and in particular to one kind is used for
The whether unimpeded test device in the dessicator of test transformer.
Background technology
Dessicator is an attached safety guard of transformator, and the connected mode of common dessicator and transformator is such as
Shown in Fig. 1.The body of dessicator 07 is transparent glass vessels, and inside fills variable color silica gel 09 as desiccant, dessicator's body
Upper end be connected with the rubber capsule 05 in the oil conservater 04 of transformator 01 with connecting leg 02 by flange 06；The basis of dessicator 07
Body bottom carries lubricating cup 08, fills transformer oil, as the defecator at dessicator's air ports in lubricating cup 08.Transformator
Transformer oil is filled in 01.Dessicator 07 in normal operating conditions, when transformator 01 due to load or ambient temperature change
And when so that the volume of transformer oil is expanded, transformer oil passes through connecting tube 02 and gas relay 03 is pressed into oil conservater
In 04 so that gas in oil conservater 04 by dessicator 07 come air-breathing and aerofluxuss, thus leading to have in lubricating cup more obvious
Bubble rolls so that whether staff's observation dessicator is unimpeded.But, in summer high-temperature or transformator 01 running overload
In the case of, if dessicator 07 blocks or hypopnea, transformer oil volumetric expansion, the oil level in oil conservater 04 rises, and squeezes
Pressure rubber capsule 05, due to dessicator's blocking, air cannot pass in and out, and after rubber capsule 05 is compressed, its internal air volume subtracts
Little, pressure increases, and leads to transformator false oil level (the actual oil level of transformator has difference with outside instrument reading) or pressure
Discharge showing of (being automatically releasable the protection device of the transformator of pressure after inside transformer pressure increases above warning value) action
As if now carrying out more changing jobs of variable color silica gel 09, then be removed in a flash in dessicator 07, transformer oil will
Pour into rapidly oil conservater 05, (gas relay is to be connected in oil circuit to oil stream, is to become by the baffle plate promoting in gas relay 03
The protection device of depressor internal fault, when there is catastrophe failure in inside transformer, it will produce substantial amounts of gas, in connecting leg
Produce oily flow phenomenon, the protection baffle plate in this device is just promoted by oil stream, when baffle plate moves to a certain defined position, is switched on
Trip circuit, the power supply of disconnecting transformer, play the effect of protection transformator), cause protection misoperation, transformator 01 is stopped transport,
Have a strong impact on the reliability of power supply.Therefore change silica gel 09 before it is necessary to ensure that dessicator 07 breathe unimpeded.Transformator due to
Temperature, power load uncertain, transformer oil volume is expanded with heat and contract with cold very small sometimes, therefore in the lubricating cup 08 of dessicator 07
Bubble is sometimes very inconspicuous, observes to staff and brings difficulty, affects work efficiency.

The operation principle of the unimpeded test device in portable transformer dessicator of the present embodiment and work process are summarized as follows:
See Fig. 1 and Fig. 7, during use, by the unimpeded test device in portable transformer dessicator of the present embodiment pass through its
The installation connecting hole 11 in four corners of one valve body 1 is serially connected between dessicator 07 and flange 06 with bolt and sealing ring sealing,
Now 2 respiratory ventilation holes 12 of the first valve body 1 and inflate venthole 13 upwards be connected air and communicate, 2 of the first valve body 1
Respiratory ventilation hole 12 is communicated with dessicator 07 downwards.When dessicator 07 is working properly, by 2 respiratory ventilation of the first valve body 1
Hole 12 eupnea.
When the variable color silica gel 09 in dessicator 07 needs to change, need first to detect whether dessicator 07 is unimpeded, detection is only
Need the pull handle 41 manually holding piston component 4 to be evacuated and inflated to can achieve:
During pumping, when piston 43 is by outer pull-out to the right, exhaust tube 3 is interior to be negative pressure, leads to extraneous product internal with pump bowl
A raw pressure reduction, the active force that this pressure reduction produces acts on the bottom of lower steel ball 62, forces lower spring 52 to deform upon, air by
The bottom gap of the air inlet 81 of the second tap bolt 8 and lower steel ball 62 enters exhaust tube 3 to both sides, when filling in exhaust tube 3
After air, inside and outside differential pressure disappears, and lower spring 52 recovers elastic deformation, withstands lower steel ball 62 and shuts air inlet 81, pumping terminates；
When inflating, when piston 43 is advanced to the left, force air in exhaust tube 3 to enter upper lower spring, when air to
During lower motion, because air inlet 81 is closed by lower steel ball 62, and when pressure is bigger, the closure of lower steel ball 62 is better, because
This air can only move upwards, acts on steel ball 61, forces spring 51 that elastic deformation occurs, air is by the bottom of upper steel ball 61
Portion gap is to two lateral movements, until inflating venthole 13 to the first valve body 1, is connected with connecting leg 02 due to inflating venthole 13,
Therefore air eventually enters in the rubber capsule 05 within oil conservater 04, arrives this, and the pumping of one bout and the process of inflating terminate.
Repeat above action, after being evacuated back and forth and inflating, the air pressure within rubber capsule 05 is more than outer
Boundary's air pressure, leads to the air within rubber capsule 05 to move downward along connecting leg 02, and 2 breathings through the first valve body 1 are logical
Pore 12 arrives dessicator 07, if now substantially can see bubble in lubricating cup 08, illustrates that dessicator 07 breathes unimpeded, has tested
Become, can start to change the work of the variable color silica gel 09 in dessicator 07.
To sum up, the unimpeded test device in portable transformer dessicator of the present embodiment, structure is simple, cost is relatively low；Volume
Less, about, can easily be placed on the palm of the hand；Lighter in weight, about 2.2kg, are easily installed maintainer and carry；
Only need to during installation be serially connected between flange and dessicator with bolt, easy for installation, time saving and energy saving；Only need to during test lash gas
About 5～10 seconds, you can effectively judge whether dessicator is unimpeded, than traditional method, work efficiency is greatly improved.
Above example is the explanation of the specific embodiment to the present invention, rather than limitation of the present invention, relevant technology
The technical staff in field the spirit without departing from the present invention and in the case of, can also make various conversion and change and obtain phase
Corresponding equivalent technical scheme, therefore all equivalent technical schemes all belong in the scope of patent protection of the present invention.
