Abstract
An electronic voltage transformer matching with a high-voltage GIS (Gas Insulated Switchgear) comprises a transformer main body, a cable contact head, a primary high voltage winding and an amorphous core. The amorphous core is arranged at the center of the transformer main body; a secondary winding is wound at the right side of an insulating layer of the amorphous core; the insulting layer and the primary high voltage winding are respectively arranged at the outer layer of the secondary winding; epoxy resin mixed glue is poured in the residual space of the transformer main body; and the cable contact head and an aerial socket are arranged at one side of an aluminium alloy case of the transformer main body. The electronic voltage transformer is made to be an insulated fully enclosed support post structure by pouring epoxy resin, so the voltage transformer is fouling-resistant and moist-resistant and is suitable to be installed at any position in any direction. Meanwhile, the voltage transformer is wide in measurement range; no high voltage is generated in the secondary open circuit; the secondary output has low voltage signal with ultra-low power; high signals are unnecessary to be converted to be low signals; and the performance of the entire voltage transformer is quite stable.
Description
Technical field
The present invention relates to the Novel intelligent electronic type voltage transformer, refer more particularly to the supporting electronic type voltage transformer of using of a kind of high-pressure inflating cabinet.
Background technology
Along with the develop rapidly of electronic technology, microcomputer type relay protection and intellectual ammeter have progressively occupied leading position, in relaying protection and measuring, and the energy flow of control section and separate from information flow, thereby monitoring equipment no longer needs the instrument transformer of high-power output.Simultaneously because the fast development of power industry, the integrated automation of transformation stations and
Therefore the application of power distribution automation is developed a kind of high-pressure inflating cabinet with measurement, protection and ability to communicate supporting extremely urgent with electronic type voltage transformer.
Summary of the invention
Purpose of the present invention just provides a kind of supporting electronic type voltage transformer of using of high-pressure inflating cabinet brand-new, compact conformation.
?
The object of the present invention is achieved like this, high-pressure inflating cabinet is supporting to be comprised of current transformer body, cable contact head, high pressure winding and amorphous core with electronic type voltage transformer, it is characterized in that: the current transformer body center is provided with amorphous core, the insulating barrier right side of amorphous core is wound with secondary winding, and the secondary winding skin is respectively arranged with insulating barrier and a high pressure winding; Remaining space in the described current transformer body is cast with epoxy resin mixed glue, and a side of the aluminum alloy casing of current transformer body is provided with cable contact head and aviation socket.
The present invention adopts poured with epoxy resin to become insulated full-enclosed column support type structure, and anti-pollution and humidity are suitable for any position, any installation direction; Measuring range is wide simultaneously, and second open circuit can not produce high voltage, and secondary is output as the small voltage signal, and power is minimum, does not need large-signal is converted into small-signal, and the performance of whole product is highly stable.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure 1, instrument transformer suspension ring 2, current transformer body 3, cable contact head 4, secondary winding 5, high pressure winding 6, epoxy resin mixed glue 7, aluminum alloy casing 8, aviation socket, 9, amorphous core.
Embodiment
Below in conjunction with accompanying drawing invention is described further:
A kind of high-pressure inflating cabinet is supporting to be comprised of current transformer body 2, cable contact head 3, high pressure winding 5 and amorphous core 9 with electronic type voltage transformer, it is characterized in that: current transformer body 2 centers are provided with amorphous core 9, the insulating barrier right side of amorphous core 9 is wound with secondary winding 4, and secondary winding 4 skins are respectively arranged with insulating barrier and a high pressure winding 5; Remaining space in the described current transformer body 2 is cast with epoxy resin mixed glue 6, and a side of the aluminum alloy casing 7 of current transformer body 2 is provided with cable contact head 3 and aviation socket 8.
During implementation, the present invention adopts amorphous iron core 9 to make the series inductance voltage divider, adopts semiconductive crimped paper and copper braid intersection coiling shielding behind the coil winding; Ground connection after coil and secondary aviation plug terminal directly link to each other, the secondary outgoing line of coil links to each other with the aviation plug terminal with Shielded Twisted Pair.Surface of the present invention with shielding, has been eliminated the impact of external magnetic field on product with aluminium alloy, so that small product size is less, performance is more excellent.
