电气火灾探测器

Electrical fire detector 

所谓漏电，就是线路的某一个地方因为某种原因（自然原因或人为原因，如风吹雨打、潮湿、高温、碰压、划破、磨擦、腐蚀等）使电线的绝缘或支架材料的绝缘能力下降，导致电线与电线之间（通过损坏的绝缘、支架等）、导线与大地之间（电线通过水泥墙壁的钢筋、马口铁皮等）有一部分电流通过，这种现象就是漏电。 当漏电发生时，漏泄的电流在流入大地途中，如遇电阻较大的部位时，会产生局部高温，致使附近的可燃物着火，从而引起火灾。此外，在漏电点产生的漏电火花，同样也会引起火灾。

Means that there is leakage line somewhere for some reason (natural or man-made reasons, such as wind and rain, damp, high temperature, contact pressure, piercing, friction, corrosion, etc.) to make the insulation of the wires or loss of the insulation of the scaffold material, cause between wires and wire (through the damaged insulation, bracket, etc.), between conductor and earth (wire through the cement wall of steel, tin, etc.) are part of an electric current passes through, the phenomenon is the leakage. When leakage occurs, the leakage current on the way into the earth resistance in case of a larger area, can produce local high temperature, fuel near the fire, causing a fire. In addition, the leakage points of leakage, will also start a fire. 

电气火灾监控系统应由下列部分或全部设备组成：电气火灾监控器；剩余电流式电气火灾监控探测器；测温式电气火灾监控探测器。

Electric fire monitoring system should be composed of some or all of the following equipment: electrical fire monitor; Residual current electrical fire monitoring detector; Temperature measuring type electrical fire monitoring detector.
