电线短路是引发火灾的常见原因之一。短路即电气线路的火线与火线或火线与地线在某一点联碰在一起，使电流不经过负载而形成回路的现象。短路分为相间、线间短路，俗称碰线、混线或连电。 短路的危害 １．短路时，由于回路电流增大，在短路处易产生强烈的火花和电弧，同时使金
One of the common causes of fire is wire short circuit. Short circuit that is the electrical line of the FireWire or FireWire and the ground at a certain point touch together, so that the current flow through the load and the formation of the loop. Short circuit is divided into white, short circuit between lines, commonly known as touch line, mixed line or even electricity. Hazard of short circuit Short circuit, due to the loop current increases, in the short circuit is easy to produce a strong spark and arc, while gold
