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 [0001] The invention relates to a metal-sealed terminal board, which is suitable for GIS electronic transformers of power primary equipment. Background technique [0002] With the continuous development of the power system, the voltage level of power transmission and transformation equipment is getting higher and higher, which puts forward new requirements for the development of new electronic transformers. The traditional wiring terminal board is mostly in the form of epoxy resin casting, and a certain number of copper wiring studs are arranged in the center of the terminal board. When wiring, the head of the signal line is mostly welded to the cold-pressed joint first, and then the cold-pressed joint is fastened to the stud of the terminal board by screws. But this kind of terminal has certain defects: [0003] The shielding effect is not good, and the secondary sampling or output signal is easy to receive external interference; [0004] Repeated disasse...
