城市综合管廊舱构式变电站隔离特性论证

Demonstration of isolation characteristic of Cabin type substation in urban comprehensive pipe gallery

针对综合管廊配电节点处无隔离措施的现象,阐述舱构式变电站在综合管廊应用的可避险功能,提出综合管廊节点安全保障的核心特征,是综合管廊与舱构式变电站之间的隔离措施。结合国家电气相关规范对管廊变电站设置要求尚无规定,指出预留操作间距、检修通道的必要性,及其对危险环境避险应用的重大意义。同时根据管廊所处的道路情况,充分利用管廊舱构式变电站的地面与地下隔离措施,优化管廊变电站靠近电源、靠近负荷中心的供电方法,并将路面照明及其控制用电设备一并结合纳入管廊舱构式变电站的供电系统,避免和减少地面变电站占用土地。

Based on the comprehensive pipe Gallery distribution node without the phenomenon of isolation measures, this Cabin type substation of substation can be safe in the composite pipe gallery application function, put forward the core of the Comprehensive pipe Gallery node security features, is a comprehensive pipe Gallery and isolation measures between the Cabin type structure type transformer substation. Combining with the national electrical related specification requirement for pipe gallery substation Settings insufficient , Points out the necessity of the reserved channel spacing operation, maintenance, and its significance on the application of the dangerous environment safety. At the same time, according to the pipe rack of road conditions, make full use of the pipe gallery module structure type of the ground and underground substation isolation measures, optimization of pipe gallery substation near the power supply, close to the center of the load power supply method, and will road lighting and control electricity equipment together comprehensive pipe Gallery class frame Cabin type substation of power, and to out avoid and reduced ground substation occupied land of solution approach.
