| 什么叫短路？短路会造成什么后果？ What is short circuit? What are the consequences of a short circuit? 如果电源通向负载的两根导线不经过负载而相互直接接通，就发生了电源被短路的情况。 If the two wires from the power supply to the load are directly connected to each other without passing through the load, the power supply is short circuited. 因短路电流比正常工作电流大得多，这样大的电流能导致电气设备的过热，甚至烧毁电气设备，引起火灾。同时，短路电流还会产生很大的电动力，造成电气设备损坏，严重的断路事故甚至还会破坏电力系统的稳定，所以对运行中的电气设备应采取一定的保护措施，如安装自动开关，熔断器等。 Because the short-circuit current is much larger than the normal working current, such a large current can cause overheating of electrical equipment, or even burn electrical equipment, causing fire. At the same time, the short-circuit current will generate a lot of electric power, which will cause damage to electrical equipment, and even damage the stability of the power system. Therefore, certain protective measures should be taken for the electrical equipment in operation, such as the installation of automatic switches, fuses, etc. |
