电缆集中接地箱的主要部件
Main parts of cable centralized grounding box
电缆集中接地箱通常包括汇流铜母排、电流互感器、绝缘小磁柱以及电流回路二次端子排（含铜排、流互、端子排等）这些部件。箱体内设互感液压钢坝器二次保护接地小铜排，与互感器二次保护接地进行连接，箱体内部侧面安装电流互感器二次接线端子排，安装牢固，接线可靠。箱体下部设电缆头固定支撑或支架，便于输入、输出回流电缆的安装与固定。
Cable centralized grounding box usually includes copper bus bar, current transformer, insulated small magnetic column and current circuit secondary terminal block (including copper bar, current transformer, terminal block, etc.). A small copper bar for secondary protection grounding of transformer is set in the box, which is connected with the secondary protection grounding of transformer. The secondary wiring terminal block of current transformer is installed on the inner side of the box, which is firmly installed and connected reliably. Cable head fixed support or bracket is set at the lower part of the box to facilitate the installation and fixation of input and output return cables.
