Technical field
The utility model is related to transmission system technical field, it particularly relates to a kind of high withstand voltage transformer device structure.
Background technology
Transformer is exactly that one kind utilizes mutual electromagnetic inductance, voltage of transformation, the device of electric current and impedance.It is general to have primary and secondary
Two separate coils of level, when the alternating current on primary is logical, the alternating current just as frequency, transformer can be induced in secondary
Primary and secondary coil turn ratio be equal to voltage ratio.
In flexible transmission system regions, the demand of power supplies for high voltage circuit often occurs.It is required that the isolation of power supply is pressure-resistant
It is very high.The isolation of power supply relies primarily on its internal transformer and realizes isolation.Therefore, the pressure-resistant of transformer determines isolated from power
Pressure-resistant height.But current wattage transformer isolation is pressure-resistant can not to be done up, and the isolation of small-power transformer with small volume is pressure-resistant to ask
Topic is a technical bottleneck in industry.
The problem of in correlation technique, effective solution is not yet proposed at present.
Utility model content
The purpose of this utility model is to provide a kind of high withstand voltage transformer device structure, can solve the problem that existing wattage transformer every
From the pressure-resistant technical problem such as can not do Shang Qu.
The purpose of this utility model is achieved through the following technical solutions：
A kind of high withstand voltage transformer device structure, it includes two U-shaped magnetic cores being oppositely arranged, section of described two U-shaped magnetic cores
Face is relative two-by-two, high withstand voltage insulation barrier is provided between the section of described two U-shaped magnetic cores, the U-shaped magnetic core and high withstand voltage are exhausted
Edge baffle plate constitutes closed magnetic circuit；Primary coil winding and secondary coil winding, primary line are respectively equipped with described two U-shaped magnetic cores
Enclose winding outer cladding heat-conducting filler.
Further, the high withstand voltage insulation barrier is epoxy resin board, plastic plate or glass plate.
Further, the number of turn of the secondary coil winding is less than or equal to 50000 circles.
Further, the cross section of the U-shaped magnetic core is square, circular or rectangle.
Further, conductive filler body is the mixture of quartz sand or quartz sand and resin.
The beneficial effects of the utility model：By resistance in two sections U-shaped core cross section middle setting height facing each other
Insulation barrier is pressed, and in primary coil outer cladding heat-conducting filler, effectively realizes wattage transformer and isolates pressure-resistant do not
Up the problem of, the pressure-resistant problem of isolation of wattage transformer is thoroughly solved, is provided so as to be applied for the resistance to voltage source of high isolation
Technical support.
