Abstract
An embedded wire outlet step flange is designed to aim at solving the problems that in order to achieve intelligence, a current transformer and the like for providing output signals are arranged in a transformer; a power supply required by a secondary wire and an intelligent of the current transformer needs to be led out from the inside of the transformer from the lateral wall of an oil tank; and oil is prone to leak. The embedded wire outlet step flange enables wiring to be simple and convenient and appearance to be attractive. The embedded wire outlet step flange comprises a flange main body, thread holes are evenly distributed along the periphery of the flange main body, annular sealing grooves are arranged at the peripheries of the thread holes, a boss is arranged on the lateral side of the flange main body around the axis, and a groove is arranged on the other side of the flange main body around the axis. The embedded wire outlet step flange can meet requirement for installation and dismounting convenience, guarantees sealing performance of the connection ports, simultaneously guarantees the insulation distance from the secondary wire to the wall of the oil tank of the transformer and the flange and enable the transformer to be concise and attractive in the whole appearance.
Description
Technical field:
The utility model relates to a kind of flange, relates in particular to a kind of embedded wire outlet ladder flange, the flange that is connected between the electric coupler that is used for intelligent transformer and the fuel tank, be mainly used in intelligent grid for transformer substation system.
Background technique:
Fast development along with power industry, intelligent grid has become development trend, the intelligence part of at present a lot of intelligent transformers all has been added in the inside of transformer, can judge very accurately running state and the transformer oneself state of transformer by the data of intelligent terminal.Realize intellectuality, transformer inside need to add some current transformers that need output signal etc., and the required power supply of the secondary line of all current transformers and intelligent object all needs to draw by the fuel tank sidewall from transformer inside.Structural feature for present full-sealed transformer, draw this structure, should guarantee that transformer is installed, the convenience of dismounting, guarantee again the sealing of this interface, also will guarantee simultaneously secondary line apart from the insulation distance of tank wall and flange and transformer overall appearance etc., these all are the problems that needs to be resolved hurrily at present.
The model utility content:
The utility model is in order to solve present transformer in order to realize intellectuality, needs are provided the current transformer etc. of output signal place transformer inner, all need from transformer inside to draw by the fuel tank sidewall and avoid the leakage of oil problem and make wiring simple and convenient and need to solve the secondary line of current transformer and the required power supply of intelligent object, can make again simultaneously the also problem such as better appearance of profile, adopt following technical proposals: embedded wire outlet ladder flange, it comprises flange body, on described flange body, be evenly equipped with tapped hole along contour; The outer annular seal groove that is arranged with at described tapped hole; Be provided with boss in the flange body that is provided with the annular seal groove one side around the axle center, be provided with groove at described flange body another side around the axle center.
The utility model is owing to adopt the mode of embedded ladder adpting flange, both satisfied the convenience of installation, dismounting, guaranteed again the sealing of interface, will guarantee also that simultaneously secondary line is apart from insulation distance and the transformer overall appearance of tank wall and flange.
Description of drawings:
Fig. 1 is structural representation of the present utility model
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is use view of the present utility model.
Embodiment:
See figures.1.and.2, embedded wire outlet ladder flange, it comprises flange body 1, on described flange body 1, be evenly equipped with tapped hole 3 along contour, described tapped hole 3, with on the transformer oil tank wall to be connected position of opening, size and quantity corresponding, be used for and oil tank wall is fixed; At the outer annular seal groove 2 that is arranged with of tapped hole 3, by described annular seal groove 2, make between ladder flange and the transformer oil tank wall and realize being tightly connected, guaranteed the excellent sealing between adpting flange and the oil tank wall; Be provided with boss 4 in the flange body 1 that is provided with annular seal groove 2 one side around the axle center, described boss 4 just with the transformer oil tank wall on the groove interlocking fill and lead up, with annular seal groove 2 formation sealing surfaces; Be provided with groove 5 at described flange body 1 another side around the axle center, give the insulation distance location that goes between to oil tank wall and flange by described groove 5, guarantee the insulation distance of lead pitch oil tank wall and flange.
Referring to Fig. 3, during use, the electric coupler that connects good line is fixed on four the most inboard holes of ladder flange, sealing gasket is positioned in the annular seal groove.Behind the device body nowel, it is suitable by case upper part of the cover hand hole this staged flange position to be placed, and at the fuel tank outer wall fixing bolt is tightened, and guarantees good seal.When suspended core, open the sidewall bolt, by the case lid hand hole ladder flange and electric coupler are taken off and place transformer safer place with it, then the device body is hung out.Be unlikely to lead-in wire is damaged.This kind structure has guaranteed the convenience of transformer installation, dismounting, has guaranteed again the sealing of this interface, will guarantee also simultaneously that secondary line is apart from insulation distance and the transformer overall appearance of oil tank wall and flange.
