Gasket is connected to, the gasket and cylinder are slidably connected, and the lower section of the cylinder is equipped with card column, and card column is located at transformer body
On inner wall, the top of the transformer body is equipped with opening, and it is interior equipped with cover, the side of the cover and transformer sheet to be open
Body is hinged, and the bottom of cover is equipped with buckle, and the buckle matches respectively with fixed link and card column, the transformer body
Inner wall is equipped with fixed column.The structure of the invention is simple, and cost is relatively low, economical and practical, and occupies little space.
In using foregoing invention solution processes, since transformer use for a long time can generate heat, heat dissipation can cause not in time
Coil heating is serious, leads to the easy aging of the insulating layer on coil, so as to security risk occur.
Invention content
The purpose of the present invention is providing high-power transformer, to solve to make not in time due to radiating during transformer use
The problem of into security risk.
In order to achieve the above object, base case of the invention is：The method of work of potential device, using high-power transformation
Device carries out transformation, and method of work is as follows：
(1) preparation is equipped with pillar into the seal cavity of push plate and case top full of cooling oil, housing bottom,
Pillar is equipped with iron core, and iron core one end is equipped with primary coil, and the iron core other end is equipped with secondary coil；
(2) high-power transformer is accessed in circuit, primary coil and secondary coil is accessed in circuit, primary coil and secondary coil
There are resistance, primary coil and secondary coil to generate heat after being powered, as primary coil and secondary coil are constantly powered, the temperature in housing is not
Disconnected raising, temperature increase the air expansion in back casing, and air expands against push plate and moved to case top；
(3) transformer cools down, and push plate is moved to case top, the hose of push plate lower end is driven to move up, hose is with pushing away
The upper surface of plate connects, and the pillar in iron core is equipped with stent, and stent is equipped with the roller being rotatablely connected with it, stent and roller
Between be equipped with torsional spring, the fan for being secured to connection is equipped in roller by shaft, soft tube winding is set in roller appearance, roller
It is useful for the lantern ring of fixed hose；Push plate moved to case top push cooling oil between push plate upper surface and case top to
Soft in-pipe；Meanwhile push plate moves to case top and hose is pulled to be moved to case top, hose movement drives roller to turn
Dynamic, torsional spring is tightened in roller rotation, and roller rotation drives the fan rotation in roller, and fan rotation accelerates primary coil and by-pass
Air flowing between circle, meanwhile, the cooling oil in hose absorbs the heat that primary coil and secondary coil generate, and starts to drop in housing
Temperature；
(4) heat transfer, in housing after cooling, torsional spring sets back, and torsional spring, which sets back, drives roller to opposite anti-
To rotation, roller rotation drives fan to fill in the opposite direction, and fan rotation is driven around primary coil and secondary coil again
Air flows, and the heat that primary coil and secondary coil generate is taken away in air flowing；
(5) heat distributes, and push plate, which moves back and forth, pushes cooling oil movement, and cooling oil movement generates primary coil and secondary coil
Heat absorb in time, heat at the top of housing by being dispersed into air.
The operation principle of this base case is：It before high-power transformer is used, is first accessed in circuit, due to pushing away
The top of plate and housing slidingly and sealingly connects, so, coolant is first full of between the upper surface of push plate and housing；Due to soft
Pipe is stretched between push plate and upper part of the housing, and therefore, the cooling liquid energy of push plate upper surface enters in hose；Primary coil of transformer and
Secondary coil after energization due to starting to work, since coil has resistance, coil to start to generate heat after being powered；After coil heating, housing bottom
Air between portion and push plate is heated, and air expands after being heated, since push plate can be slided on housing, push plate with
Push plate is pushed to slide after the air heats of housing bottom；Since coolant is full of above push plate between upper part of the housing, it pushes away
Plate, which slides, pushes coolant movement, in coolant flow to hose；Since the pillar in iron core is equipped with stent, stent is equipped with
The roller being rotatablely connected with it, soft tube winding is on roller, and therefore, hose, which moves up, pulls roller rotation；Due in roller
Equipped with the fan being fixedly connected, therefore, roller rotation drives fan rotation, and fan rotates the flowing of the air around driving, air
The energy of flow in time dispels the heat that iron core, primary coil and secondary coil generate, and heat can in time be absorbed by push plate and hose, and will
Heat is transmitted to the top of housing by heat transfer to coolant, coolant, and is distributed heat in air；Due to being set on roller
The lantern ring of fixed hose is useful for, therefore, without departing from roller after hose drive roller rotation；When iron core, primary coil and by-pass
When heat between circle is reduced, the temperature around iron core reduces, and torsional spring drives reset roller rotation, and hose is rotated and drawn with roller
Dynamic push plate is moved to close to one end of iron core, since the pressure between push plate upper surface and upper part of the housing reduces, so coolant
It flows back between push plate and case top；Due to being equipped with torsional spring between roller and stent, it is acted on after roller rotation in torsional spring
Line is rotated backward to opposite, and fan is driven to rotate in the opposite direction, again between band dynamic iron core, primary coil and secondary coil
Air circulation radiates to iron core, primary coil and secondary coil, is rotated by drum reciprocating, can rise to iron core, primary coil and pair
Coil plays preferable cooling effect.
The advantageous effect of this base case is：By setting the push plate slidingly and sealingly connected in the upper housing, it is convenient for
Coolant is filled between push plate upper surface and upper part of the housing, by setting stent on the pillar in iron core, is set on stent
Have the roller being rotatablely connected with it, convenient for by soft tube winding on roller, hose and stent and iron core, primary coil and secondary coil
Distance is near, convenient for absorbing the heat that iron core, primary coil and secondary coil come out in time, radiates in time to transformer；In roller
Between torsional spring is set, in roller setting be secured to the fan of connection, fan is driven to rotate when rotate convenient for roller, can in time by
Heat around iron core can also prevent dust from falling in iron core, primary coil and secondary coil surface influence transformation effect by blowing away
Fruit；The cooling oil temperature in the hose on roller is wrapped in less than enclosure interior, fan rotation blowout air temperature is low, can be to former line
Circle and coil play preferable cooling effect；Cooling oil storage is more between push plate upper surface and upper part of the housing, cold in hose
But cycle can be generated after oil temperature raising, has relatively low temperature convenient for the cooling oil in hose, conducive to the heat absorbed around hose
Amount；It is set on roller for fixing the lantern ring of hose, by torsional spring and lantern ring by soft tube winding roller after being rotated convenient for roller
On.
