Primary Disconnect 一次隔离触头

The primary disconnect finger set is rugged and easy to inspect .Designed for optimum contact , built of silver-plated copper and
tested for continuous and short time current. Cycloid design is more convenient to connect and expand wider contact area than
flat design.These disconnects provide proper contact integrity throughout the life of the gear for the critical primary disconnect
function.Unpacking and Installation；

一次隔离触头坚固耐用且易于检查。为实现最佳接触而设计，由铜片镀银制成，并经过了连续和短时电流测试。梅花触头设计比扁
平触头设计更方便连接和扩大接触面积，这些一次触头在开关柜的整个使用寿命期间提供可靠的电气接触，从而起到关键的主要隔
离、连接功能。

抽出式断路器关门操作

For safty reason, Only breaker compartment door close, Breaker can be rack to CONNECT position; And only breaker rack back
to TEST position, Compartment door can be open.

基于安全考虑，只有断路器隔室门关闭，断路器才能被摇进到工作位置；只有断路器回到试验位置，断路器隔室门才能被打开。

Interlock System 联锁系统

For personnel safety, VB is designed with a number of mechanical and electrical interlocks. For example, breaker contacts must
be open before the breaker can be moved to or from the CONNECT position. And only breaker at
CONNECT/TEST/DISCONNECT position, Breaker can be closed.

Mechanical interference interlocks are provided to permit only the insertion of properly rated breakers into any specific
compartment.

Interlock between breaker rack mechanism and earthing switch, Breaker can not be racked to CONNECT position when panel
earthing switch is closed, also provide positive plate to make earthing switch can not be close when breaker at CONNECT
position.

These and other necessary interlocks provide a comprehensive protection system.

为了人员安全，VB 设计有许多机械和电气联锁。 例如，必须先使断路器分闸，然后才能将断路器移入或移出工作位置。 只有断
路器在隔离、试验、断开位置时才能合闸；

机械互锁装置，仅允许将适当额定值的断路器推入特定的开关室。

断路器摇进机构与接地开关之间联锁，当接地开关在合闸时，断路器不能被摇进到工作位置；同样提供联锁板使断路器在工作位置
时，接地开关不能合闸；

这些和其他必要的联锁提供了全面的保护系统。
