我国电力系统常用的中性点接地方式有:中性点直接接地、中性点不接地、中性点经消弧线圈接地(谐振接地)、中性点经电阻接地这四种方式。电力系统接地运行方式涉及电网的安全运行、供电可靠性、用户用电安全等诸多重要问题。在专业技术方面涉及电力系统、过电压与绝缘配合、继电保护、通信与自控、电磁兼容、接地设计等诸多领域，是一个内容广泛的系统问题。变压器中性点接地电阻柜是包括接地变压器在内的成套接地设备，可安装于发电厂厂用电系统、变电所供电系统、工矿企业配电系统中，实现这些电网采用中性点经电阻接地的系统运行方式。聚氨酯软管 PVC软管 隔离墩模具 u型槽模具 护坡模具 pvc输送带 尼龙输送带 天津除甲醛 北京除甲醛
There are four common neutral grounding modes in China's power system: neutral direct grounding, neutral non grounding, neutral grounding through arc suppression coil (resonant grounding) and neutral grounding through resistance. The grounding operation mode of power system involves many important problems, such as the safe operation of power grid, power supply reliability, user power safety and so on. In terms of professional technology, it involves many fields, such as power system, overvoltage and insulation coordination, relay protection, communication and automatic control, electromagnetic compatibility, grounding design and so on. Transformer neutral grounding resistance cabinet is a complete set of grounding equipment including grounding transformer, which can be installed in auxiliary power system of power plant, power supply system of substation and distribution system of industrial and mining enterprises to realize that these power grids adopt the system operation mode of neutral grounding through resistanc
