|户内型过电压保护器可以水平安装在各种不同型号的开关柜内,该类过电压保护器除直接与开关柜“A”、“B”、“C"三相及接地相(“D”相)相连的, 线鼻子为裸导体外,其余部分被绝缘体封闭,因此过电压保护器的相间、相对地(或柜体)的距离及对柜体安装空间要求相应较小,可直接安装在开关柜的手车底盘内或互感器, 室内。
The indoor overvoltage protector can be installed horizontally in various types of switchgear cabinets. The overvoltage protector is directly connected with "A", "B", "C" three-phase and grounding phase ("D") of the switchgear cabinet, and the wire nose is bare conductor. The rest of the overvoltage protector is sealed by insulators. Therefore, the overvoltage protector is phase-to-phase (or) relative to each other. The distance of cabinet body and the requirement for installation space of cabinet body are relatively small. It can be directly installed in the chassis of handcart or transformer or indoor of switchgear cabinet.
