建筑物低压线路漏电引起火灾,可发生在相线、相线与中性线、相线与大地之间。低压线路漏电引起火灾,是造成线路电气原因火灾中较为特殊的和难以防止的一种,它往往又是造成线路短路火灾的隐患。即便是近几年国家有关电气安全的规范、标准、规程不断的修订而完善各种安全保护措施,至今也还未能对直接防止漏电引起线路火灾作出较为系统全面的规定(仅从漏电保护用于线路防触电保护、 Leakage of buildings caused by a low voltage power line fire, can occur in the phase, phase and neutral, phase and earth. Leakage caused by low voltage line fire, is caused by the electrical circuit because the fire is more special and difficult to prevent a kind of, it is often caused by a short-circuit fire line hidden danger. Even in recent years, the state of the electrical safety standards, standards, rules and constantly improve and improve a variety of safety protection measures, has so far failed to directly prevent leakage caused by the line fire to make a more systematic and comprehensive provisions (only from the leakage protection Protection against line electric shock,
