The external insulation and main insulation and the connection between the high-voltage coil and the silicon rubber cable must Potting with epoxy resin under vacuum, this kind of transformer has large electrical ratio, high safety, small occupation area, strong insulation performance, and is suitable for use in harsh environments such as high altitude and high humidity.
Description
Technical field
The utility model relates to a kind of voltage transformer, particularly relates to a kind of voltage transformer of cable seal formula.
Background technology
The high pressure silicone rubber for cable of market flexibility only has a kind of pattern as the sealed type voltage transformer of lead-in wire before this, be that high pressure silicone rubber for cable line and device body junction are with silicon rubber embedding curing molding under normal pressure, though the silicon rubber of high pressure silicone rubber for cable line and embedding can be bonded together, but the main insulation in the instrument transformer and the longitudinal insulation of high-tension coil are because silica gel viscosity is big, embedding exists air-gap insulation that obvious hidden danger is arranged, silicon rubber itself is unfavorable for heat radiation in addition, it is aging to quicken built-in electrical insulation like this, reduction of service life.So the electric instrument transformer of this insulation coordination is pressed in, and use is problematic on the electric power.
Summary of the invention
The purpose of this utility model is the voltage transformer that is to provide a kind of poured with epoxy resin sealed type insulation, the high-tension coil input is to connect as lead-in with flexible high pressure silicone rubber for cable line, epoxy resin embedding under vacuum will be used in exterior insulation and main insulation and high-tension coil and silicone rubber for cable line junction, this instrument transformer electricity is bigger, safe than distance, area occupied is little, insulation property are strong, are fit to adverse circumstances such as high height above sea level and humidity are big and use.
The purpose of this utility model is achieved through the following technical solutions:
Cable seal formula voltage transformer, the high pressure silicone rubber for cable line of its voltage transformer high pressure input are set with the epoxy stringing or can arrive the insulating material of one with epoxy resin bonding, are consolidated with resin between insulating material and the voltage transformer outlet inner casing; The voltage transformer port of export seals silica gel admittedly, and it is stifled to have set up the silicon rubber umbrella outside silica gel.
Advantage of the present utility model and effect are:
1. the electricity of the utility model voltage transformer is bigger, safe than distance, and area occupied is little, and insulation property are strong, is fit to adverse circumstances such as high height above sea level and humidity are big.
2. the input of the high pressure of the utility model voltage transformer is introduced with flexible high pressure silicone rubber for cable line, and these two kinds of insulating material of the epoxy resin of silicone rubber for cable line and perfusion effectively are coupled to one, make it to have increased applicability.
3. the utility model voltage transformer has passed through the insulation withstand voltage 42KV test in a minute of entry, and simplifies the structure, and has saved manufacturing and installation fee.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is a left view of the present utility model;
Fig. 3 sends out figure big for the part of the utility model left view.
Embodiment
With reference to the accompanying drawings the utility model is elaborated.
As shown in the figure, the part that is embedded into by resin 5 at high pressure silicone rubber for cable line 1, the epoxy stringing of handling with surfaces externally and internally or can be inserted in the insulating material 4 of epoxy resin bonding to one, and solidify with silica gel 3 embeddings, be welded on the coil again, under vacuum state, carry out the poured with epoxy resin moulding behind the dress mould, in order further to improve insulativity, at resin and lead outlet place and increased the silicon rubber umbrella and block up 2.
The utility model is the insulation coordination of a kind of 10KV voltage transformer (comprising converter), after the device body of this voltage transformer is finished, the high-tension coil input is to connect as lead-in with flexible high pressure silicone rubber for cable line, epoxy resin embedding under vacuum will be used in exterior insulation and main insulation and high-tension coil and silicone rubber for cable line junction, this high pressure silicone rubber for cable line can sustain the 42KV high voltage, therefore this instrument transformer electricity is big more safe than distance, area occupied is little, insulation property are strong, are fit to adverse circumstances such as high height above sea level and humidity are big.
The high pressure input of the utility model voltage transformer is to introduce with flexible high pressure silicone rubber for cable line, makes these two kinds of insulating material of epoxy resin of silicone rubber for cable line and perfusion be directly bonded to one.General Insulation Test is to carry out in air, epoxy casting sealed type voltage transformer of the present utility model has then passed through the insulation withstand voltage 42KV test in a minute of entry, has verified the insulation effect that silicone rubber for cable lead-in wire and epoxy resins insulation effectively are combined together.The utility model voltage transformer has been installed in the ZW8 switch cubicle, and use the voltage transformer of 10KV to be arranged separately in addition in the very little cabinet of volume, its high-tension electricity is taken out on the inlet wire in switch cubicle by voltage transformer high pressure silicone rubber for cable line, pass two shells and send into instrument transformer, the low tension after the conversion is sent back in the switch cubicle, the maximum return of Shi Yonging is to have saved product manufacturing and installation cost so again.
