Three vacuum interrupters share a metal enclosure, with SMC phase-to-phase and earth insulation and dry-air insulation. CT23 spring-stored-energy mechanisms offer manual or electric operation. The ZW8-12G version combines the breaker with an isolating blade and can serve as a sectionalising switch; internal or external PT options are described. Ceramic interrupters use copper-chromium contacts, and silicone-rubber-covered outgoing rods support use in adverse weather and contaminated environments.
Original Chinese description
产品概述
ZW8-12系列户外高压真空断路器为额定电压12kV，三相交流50Hz的户外高压开关设备，主要用来开断关合农网、城网和小型电力系统的负荷电流、过载电流、短路电流。该产品总体结构为三相共箱式，三相真空灭弧室置于金属箱内，利用SMC绝.缘材料相间绝缘及对地绝缘，性能可靠，绝缘强度高。ZW8-12G是由ZW8-12断路器与隔离刀组合而成的，称为组合断路器，可作为分段开关使用，也可自备电源，有内置PT与外置PT。本系列产品的操动机构为CT23型弹簧储能操动机构，分为电动和手动而成。
主要特点
采用真空灭弧室，空气绝缘，配以电动弹簧操作机构，使得产品灭弧能力强，短路开断次数高，无无火灾爆炸危险，操作方便，是一种性能优良，实用性较强的产品。本产品总体结构采用三相共箱式，套管进出线，箱体内为干燥空气，电动弹簧操动机构布置在箱体的侧面，可在较严酷的环境条件下可靠使用。本产品真空灭弧室采用陶瓷外壳，杯状纵磁场触头结构，铜铬触头材料，具有优良的开断和关合短路电流能力。该产品体积小、重量轻、外型美观。真空灭弧室和绝缘支持套管设计紧凑，出线导电杆外注硅橡胶，能适应恶劣的气候条件和污秽环境。
