HA(QA)、HP(QP)系列隔离香蕉视频APP软件下载主要用于有高短路电流的配电 电路和电动机电路中,作为手动不频繁操作的香蕉视频APP软件下载、隔离香蕉视频APP软件下载和应急香蕉视频APP软件下载,并作电路保护之用。香蕉视频APP软件下载可直接开闭电动机等高电感负载,特别适用于抽屉式香蕉视频APP软件下载柜的成套装置中。
本系列隔离香蕉视频APP软件下载由刀型静触头、滚动动触头及灭弧装置组成的接触系统 均组装在由耐弧工程塑料制成的封闭底座内,能达到零飞弧。操作机构由具有 弹簧储能的连杆传动机构构成,靠弹簧力完成香蕉视频APP软件下载的分、合,使香蕉视频APP软件下载动作无关 人力操作。手柄由操作手柄和传动轴等构成,属旋转操作方式。当手柄旋转操 作时,使操作机构弹簧储能,靠储能的弹簧力释放带动动触头与静触头形成 合、分两种状态,从而达到香蕉视频APP软件下载分、合主电路的目的。
本香蕉视频APP软件下载的上部可装一个或二个辅助香蕉视频APP软件下载,每个辅助香蕉视频APP软件下载有一对电器上分 开的常开触头和常闭触头,能使控制回路明确指示香蕉视频APP软件下载主电路的通断情况。
Series HA(QA)、 HP(QP) switch-disconnector are mainly applied in the distribution circuits and motor circuits with high short-circuit currents as the power switches. As the switch handle is in rotary operation, they are especially suitable for installation and application in drawer type switch cabinets. Technical performances confirm to standards IEC60947.3 and GB14048.3.This series switches are of closed structure design. The contact system is composed of static knife contacts, moving rolling contacts and arc quenching sets that are all fitted in the sealed case made of arc resistant engineering plastic and zero arc flash out is achieved. The switching mach-anism is of reliable spring energy stored independent manual operation style.On the upper part of the. switch utmost two auxiliary switches may be quipped in, each having a set of electrical separated normal open and normal closed contacts.
