Technical scheme of the present invention is: a kind of superfrequency sensor based on high-voltage shunt reactor, containing metal shell and barricade, described metal shell is tubular, its upper end is connected with metal cover board, lower end is connected with epoxy resin board, form a closed cavity, the middle part of described cavity is provided with described barricade, described cavity is divided into two closed spaces by described barricade, the inwall of the described metal shell between described barricade and epoxy resin board is provided with fixed mount, described fixed mount is provided with amplification board, the inside surface of described epoxy resin board is provided with antenna plate, described metal shell body wall between described metal cover board and barricade is provided with aviation plug and N-type head, described antenna plate, amplification board and described aviation plug and N-type head are contacted successively by wire, described metal shell lower end is fixedly connected with a Circular Plate, and described Circular Plate is evenly equipped with bolt hole.
Bolt hole in described Circular Plate is corresponding with the bolt hole of the manhole door surrounding of high-voltage shunt reactor.Described barricade is bolted on a circular fixing plate, the outer ring surface of this circular fixing plate and the fixed seal connection of described metal shell inwall.The band bandwidth of superfrequency sensor is 0.5 ~ 1.5GHz.The shape of described antenna plate and amplification board is rectangle; Described antenna plate and amplification board bond fixing respectively with described epoxy resin board and fixed mount by anaerobic adhesive; The center of described antenna plate and the center superposition of described epoxy resin board; Described Circular Plate is made up of metal material.
The invention has the beneficial effects as follows:
1, the present invention has good external electromagnetic signal shielding effect, the electromagnetic wave that the amplification board in housing and antenna plate can be allowed to receive the inner shelf depreciation of high-voltage shunt reactor more accurately produce, easy for installation; Its antijamming capability is strong, signal bandwidth is wide, dynamic range is large, highly sensitive.
2, the xsect of inventive shell and the corresponding cooperation of the manhole door of high-voltage shunt reactor, installed by fastener, do not destroy original structure, cost is lower.
3, inventive antenna plate is close to inside epoxy resin board and is installed, and steadiness is good, and in addition, housing cavity is divided into two closed spaces by barricade, and shield effectiveness is good.
4, be provided with Circular Plate in inventive shell, barricade is bolted in this Circular Plate, easy accessibility, and good sealing effect.
5, the present invention is reasonable in design, antijamming capability is strong, highly sensitive and be easy to dismounting, be easy to promotion and implementation, there is good economic benefit.
