详细描述:TVOC-2电弧防护系统是一种电弧保护继电器，可减少电弧故障，有助于保护人员和设备。

电弧监视器是电弧防护系统的主要单元，它检测电弧光，并通过快速IGBT触点在1 ms内向附近的断路器发送电信号，从而切断电源并熄灭电弧。

电弧监视器有10个检测器输入，如果需要，可以触发多达三个具有区域选择性的断路器。多达2个扩展单元可以将光探测器的数量扩展到30个，该单元包括一个可以放置在门外侧的HMI。探测器出售的长度范围很广，以适应完整的开关设备设计。

Description: The TVOC-2 Arc Protection system is an arc protection relay that reduces arc failures and helps protect people and equipment.

The arc monitor is the main unit of the arc protection system, which detects the electric arc light and sends an electrical signal through the fast IGBT contact to a nearby circuit breaker within 1 ms, thus cutting off power and extinguishing the arc.

The arc monitor has 10 detector inputs and can trigger up to three circuit breakers with area selectivity if needed. Up to 2 expansion units can expand the number of light detectors to 30, and the unit includes an HMI that can be placed on the outside of the door. Detectors are sold in a wide range of lengths to accommodate complete switchgear designs.
