Abstract
The invention relates to a metal sealing terminal plate comprising a terminal plate body (1). The metal sealing terminal plate is characterized in that the middle of the terminal plate body (1) is fixedly provided with a plurality of electric connectors (2); each electric connector (2) is internally provided with two-phase conducting electrodes (3); and the two-phase conducting electrodes (3) are fused with the terminal plate body (1) together in a glass sintering way and are isolated by an insulating medium (4). The invention has the advantages of high strength, good shielding effect, easy and convenient electric wiring operation and convenient field installation and maintenance.
Description
Technical field
The present invention relates to a kind of metal sealing terminal plate, be 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 objective of the invention is to overcome the deficiencies in the prior art, 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 of the present invention 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.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the schematic top plan view of Fig. 1.
Among the figure: 1. terminal board body, 2. electric connector, 3. conductive electrode, 4. dielectric, 5. seal groove.
Embodiment
The present invention is further detailed explanation below in conjunction with drawings and Examples.
As shown in Figure 1, 2, a kind of metal sealing terminal plate, comprise terminal board body 1, terminal board body 1 middle part is installed with a plurality of electric connectors 2, each electric connector 2 inside has two-phase conductive electrode 3, conductive electrode 3 merges by glass sintering mode and terminal board body 1, is isolated by dielectric 4 between the two-phase conductive electrode 3.The quantity of the electric connector 2 on the terminal board body 1 is 6～12.Terminal board body 1 adopts stainless steel to make.
As shown in Figure 1, the bottom surface of terminal board body 1 has seal groove 5.
Procedure of processing of the present invention is as follows:
1, on terminal board body 1, processes location hole and seal groove 5 earlier.
2, conductive electrode 3 is fused to terminal board body 1 by the glass sintering technology, places dielectric 4 between the two-phase conductive electrode 3, guarantee insulating properties.
3, again electric connector 2 is installed on the terminal board body 1 by holding screw.
