Abstract
The utility model relates to a metal sealing terminal board, including a terminal board main body (1) characterized in that the middle part of the terminal board main body (1) is fixedly provided with a plurality of electric connectors (2), each of which is provided with a two-phase conductive pole (3) inside, the conductive pole (3) is combined with the terminal board main body (1) in a glass sintering mode, and the two-phase conductive poles (3) are separated by insulating medium (4). The terminal board has advantages of high strength, good shield effect, simple and convenient operation of electric wire connection, and easy field installation and maintenance.
Description
Technical field
The utility model relates to a kind of metal sealing terminal plate, is applicable to electric power primary equipment GIS electronic mutual inductor.
Background technology
Along with the continuous development of electric power system, the power transmission and transforming equipment electric pressure is more and more higher, and the development of new-style electronic instrument transformer has been proposed new requirement.The traditional wired terminal board adopts the poured with epoxy resin form more, and terminal board central authorities are furnished with the copper Binding post/stud of some.Be earlier with the joint of colding pressing in the welding of holding wire head mostly during wiring, be tightened on the terminal board double-screw bolt by the screw joint of will colding pressing again.But there is certain defective in this kind binding post:
Shield effectiveness is not good, and double sampling or output signal are received external interference easily;
Repeatedly easy in removing operation causes the cold weld head rupture, and the excessive Binding post/stud thread that causes of perhaps exerting oneself during tightening damages.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the metal sealing terminal plate that a kind of shield effectiveness is good, electrical wiring is simple to operation is provided.
The technical scheme that realizes above-mentioned purpose is: a kind of metal sealing terminal plate, comprise the terminal board body, terminal board body middle part is installed with a plurality of electric connectors, each electric connector inside has the two-phase conductive electrode, conductive electrode merges by glass sintering mode and terminal board body, is isolated by dielectric between the two-phase conductive electrode.
Further, the bottom surface of terminal board body has seal groove.
The quantity of the electric connector on the terminal board body is 6～12.
The terminal board body adopts stainless steel to make.
Compare with traditional terminal board, metal sealing terminal plate described in the utility model has following advantage:
The electric connector of some is housed on the terminal board, and quantity can change flexibly according to concrete configuration, and electrical wiring is simple to operation, is convenient to on-site installation and maintenance;
The terminal board bottom surface has seal groove, and air-tightness requires high, and the both sides draught head is under the leakage test situation of 0.85Mpa, and a year leak rate is not more than 5*10
-7Mpacm
3/ s satisfies the airtight requirement of all kinds of GIS with electronic mutual inductor.
The terminal board body adopts stainless steel, the intensity height, and shield effectiveness is good.
