Abstract
The utility model relates to a plug-in type voltage transformer with a fully insulated structure and a metal shell, which is formed into a three-phase group way by two single-phase fully insulated plug-in type voltage transformers with the metal shells and a three-way silicon rubber plug connector with a shield through a V-shaped connecting wire. The three-way silicon rubber plug connector is made of silicon rubber and has elasticity; the phase space of a three-phase plug is not particularly strict; the mounting is convenient; the surfaces of the transformers do not have influence electricity, can be touched, and is safe and reliable; the two single-phase fully insulated voltage transformers with the metal shells are assembled with the three-way silicon rubber plug connector and then are mounted in an inflated switch cabinet; and the voltage transformer is particularly applicable to the areas which have high altitudes, are polluted by heavy industries and have atrocious weather.
Description
Technical field
The utility model relates to electric power mutual-inductor, belongs to the electromagnetic technique category, and is particularly a kind of with metal shell, by all insulation structure of poured with epoxy resin formula sealing, the voltage transformer of all insulation band screening can that uses in the gas insulation switch cabinet.
Background technology
Press the insulation of instrument transformer to form in the existing major part for the epoxy resin mixed glue vacuum pouring.Because dielectric thickness is inhomogeneous, the instrument transformer outer surface has certain induced voltage, sometimes induced voltage is higher, the maintainer dare not touch, and also can bring potential safety hazard, the voltage transformer of existing band screening can to the low-voltage equipment operation all is semi-insulating structure, can only carry out the wiring of " Y " type connects, resonance takes place in neutral ground easily, and the accident that causes instrument transformer to burn happens occasionally.
Summary of the invention
In order to solve shortcoming in the prior art, the purpose of this utility model is that a kind of production, easily manufactured will be provided, and the security performance height can satisfy the plug-in type voltage transformer of the tangibly all insulation band metal shell in " V " type wiring surface.
The utility model is to implement like this: a kind of plug-in type voltage transformer of all insulation band metal shell, its art characteristics are to comprise the plug-in type voltage transformer of two single-phase all insulation band metal shells and the threeway connection-peg of a band shielding silicone rubber sleeve, and any two ends of threeway connection-peg connects the plug-in type voltage transformer respectively.
Winding connection terminal of described plug-in type voltage transformer all has equal insulation level, adopts " V " type mode of connection to be parallel in the power circuit.
Described plug-in type voltage transformer is an electromagnetic masking, and metal shell is a non-magnet_conductible material, metal shell ground connection.
Described plug-in type voltage transformer is installed in the gas-filled type loop-network switch cabinet.
The not attachment plug of the threeway connection-peg of described band shielding silicone rubber sleeve is the B phase.
All insulation voltage transformer device body is located in the epoxy resin mixed glue, the outside adds the non-magnetic metal shell of one deck, two HV Terminal are drawn by the top and the side of current transformer body respectively, the high pressure position overcoat shielding silicone rubber sleeve that draw on top, the high pressure position that draw the side connects an end of the three-way connection of special band shielding silicone rubber sleeve, and another voltage transformer also is like this.Two instrument transformers merge the back and constitute three-phase all insulation grafting hair style voltage transformer.Three high pressure terminations connect A, B, C three-phase respectively, because the centre is special silicon rubber three-way connection mutually, has certain elasticity, certain activity nargin, switch cubicle jack sizes and location dimension error requirements are greatly reduced, the manufacturing has more operability, and the voltage transformer earthing of casing, is zero potential, do not have Danger Electric shock risk, improve the fail safe of electric equipment.
The utility model is that two single-phase all insulation band metal shell voltage transformers and threeway silicon rubber connection-peg are formed, and is installed in the CGIS inflating switch cabinet, and particularly suitable runs on high height above sea level, and heavy industry is polluted and the harsh weather area.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: plug-in type voltage transformer 1, threeway connection-peg 2, contact 3, shielding silicone rubber sleeve 4, epoxy resin mixed glue 5, metal shell 6.
Specific implementation method
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
The plug-in type voltage transformer of all insulation band metal shell shown in Figure 1, about the threeway connection-peg 2 of the band shielding silicone rubber sleeve of plug-in type voltage transformer 1 by between the two of two all insulation band metal shells link, single-phase transformers inside is all insulation, every instrument transformer is made of two sections coils, and two sections coils have equal insulation level.
Voltage transformer device body by epoxy resin mixed glue 5 vacuum pourings in the metal shell 6 that non-magnet material is made.A high-pressure side of every single-phase transformers is drawn from plug-in type voltage transformer 1 main body top, overcoat shielding silicone rubber sleeve 4, and conductive contact 3 is installed in the upper end, contacts with the switch cabinet contact box; Every another high-pressure side of single-phase transformers is drawn from the current transformer body side, through threeway connection-peg 2 two instrument transformer side high-pressure sides is connected together, and constitutes the B phase.
Band shielding silicon rubber threeway connection-peg is a plug connector in the middle of two single-phase potential transformers, two relative connection-pegs of direction connect two single-phase potential transformer side high-pressure sides respectively, it is the B phase that another connection-peg relative with both direction becomes the connection-peg of 90 degree, the B that conductive contact 3 and switch cubicle are installed in upper end contact box mutually connects formation three-phase plug-in type band metal shell all insulation voltage transformer.
The utility model is simple in structure, and is less demanding to installation dimension, simple to operate, the security reliability height, concerning manufacturer, after separately making, two voltage transformers are assembled into one, can improve product percent of pass greatly, and induced electricity is not with on the instrument transformer surface, and is tangible, safe and reliable.
