Abstract
The present invention relates to a kind of transformer switch supporting construction, including be arranged on fuel tank internal be used for switch fixed switch mounting flange, be welded in switch mounting flange close to fuel tank tank wall side switch fixing casing, be welded in the switch mounting flange upper surface reinforcement iron vertical with switch fixing casing length direction；The tank wall fixed plate for being connected with switch fixing casing is welded with the inside of fuel tank tank wall, switch mounting flange is provided with away from fuel tank tank wall side is connected to the fixed plate for supporting switch mounting flange that iron core folder one end be arranged in parallel with iron core folder.Switch flange and supporting construction are placed on fuel tank internal by the present invention, are solved the sealing problem under high pressure, are effectively solved transformer switch completely in inside transformer, switch coordinate with lead and with reliability that fuel tank is fixed it is not enough the problem of.
Description
Technical field
The present invention relates to transformer technology field, and in particular to a kind of transformer switch supporting construction.
Background technology
In conventional structure, transformer be generally piece dissipate, body integrative-structure, switch for have load or no load switch, Gu
It is scheduled in fuel tank external flanges.When mounted, switch supporting plate is tightened with core clamping by bolt first, and then switch is placed on
Switch on supporting plate, enter line lead assembling, need switch to mention during follow-up general assembly, with fuel tank upper switches flange
Connect, on fuel tank, motor drive mechanism is then connected to by the gearcase and rotary shaft of external switch skull, switch is completed
Assembling.
But for special transformer, such as two-piece unit cooling transformer, body and the basic drop of cooler are larger, energy
Reach 12 meters.Cooler portion on the ground, body passes through drop up and down, then body will produce pressure, have in ground bottom
Voltage adjustment of on-load switch can not meet the requirement of upper-lower height difference, typically be changed to non-excitation pressure adjustment mode.It so there is no Excitation Adjustment
Compressed switch Layout Problem, and data is provided according to MR switching techniques personnel, and non-excitation pressure adjustment switch head lid is arranged in fuel tank internal.
In existing switch support structure, flange centralized arrangement is switched outside fuel tank, but in oil conservater and switch height
When drop is larger, very big pressure can be produced, switch skull can not meet the sealing problem under high pressure with fuel tank junction, hold
Easily cause switch flange seepage.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of transformer switch supporting construction
To solve the above problems, the technical solution adopted by the present invention is：A kind of transformer switch supporting construction, including set
Fuel tank internal be used for it is switch fixed switch mounting flange, be welded in switch mounting flange close to fuel tank tank wall side switch
Fixed plate, it is welded in the switch mounting flange upper surface reinforcement iron vertical with switch fixing casing length direction；On the inside of fuel tank tank wall
The tank wall fixed plate for being connected with switch fixing casing is welded with, switch mounting flange is provided with connection away from fuel tank tank wall side
The fixed plate for supporting switch mounting flange being be arranged in parallel in iron core folder one end and iron core folder.
The shape and fuel tank form fit of the switch mounting flange, for increase switch mounting flange intensity, switch is fixed
Flange upper surface is welded with two reinforcement iron, parallel arrangement, so that switch mounting flange is more consolidated.
Grounding nut is provided with described switch mounting flange.The generation of partial discharge phenomenon can be prevented.
Screw is provided with described switch fixing casing and tank wall fixed plate, switch fixing casing and tank wall fixed plate pass through spiral shell
Tether and connect.
Described fixed plate is connected with switch mounting flange by bolt.
Described fixed plate is bolted to iron core folder one end.
Described bolt is using processing of not painting.It can prevent paint film from damaging, produce partial discharge phenomenon.
Cross-over block is provided between switch mounting flange and fixed plate.It is too heavy because switching in order to prevent, fix switch
Flange is tilted and contacted with fixed plate, forms multipoint earthing.Plus cross-over block, if switch fixing casing is tilted, in fixed plate
There is insulating point cushion block to stop to contact with switch fixing casing, multipoint earthing would not be formed.
When lead is assembled, fixed plate is joined with bolts with iron core folder, then switch is placed on switch and is fixed
On flange, by pendent switch mounting flange of having driven a vehicle, switch mounting flange is sling and is connected with fixed plate.Lead is assembled
After the completion of, in general assembly, switch mounting flange is separated with fixed plate by lifting of driving a vehicle, then by tank wall fixed plate with opening
Bolt of fixing plate connection is closed, finally cross-over block is placed between switch mounting flange and fixed plate, to prevent multipoint earthing, and
The effect of supporting switch mounting flange is played, prevents switch from tilting.
Switch flange and supporting construction are placed on fuel tank internal by the present invention, solve the sealing problem under high pressure, have
Effect solve transformer switch completely in inside transformer, switch with lead coordinate and with fuel tank fix reliability deficiency ask
Topic.
