如何在电力系统中操作接地电阻柜？接地电阻柜属于中性点保护设备，接地电阻柜安装在被保护设备和地之间，可以说是一种较好的成套接地设备，在国内外已经使用了十几年，由于其本身的可靠性和实用性，所以现在国家电网规定中性点一般要加装此设备，而且经过这么多年的研究，接地电阻柜也不断得到了很好的改进和发展，具有了更广泛的应用范围，通常情况下我们可以将其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，以实现这些电网采用中性点经电阻接地的系统运行方式。 How to operate the grounding resistor cabinet in the power system? The grounding resistor cabinet belongs to the neutral point protection equipment. It is installed between the protected equipment and the ground, and can be said to be a good complete set of grounding equipment. It has been used for more than ten years at home and abroad. Due to its reliability and practicality, the national power grid generally requires the installation of this equipment for neutral points. After so many years of research, the grounding resistor cabinet has also been continuously improved and developed, and has a wider range of applications. Usually, we can install it in the power plant power system, substation power supply system, and industrial and mining enterprise distribution system to achieve the system operation mode of neutral point grounding through resistance in these power grids. 接地电阻柜的作用是：对中心点采用中间电阻接地方式，该接地可增加变压器单相接地故障电流，提高变压器保护的灵敏度，保证故障时保护能立即断开，部分解决****不接地系统中性点偏移引起的非故障相电压升高，限制电容电流。 The function of the grounding resistor cabinet is to use an intermediate resistor grounding method for the center point. This grounding can increase the single-phase grounding fault current of the transformer, improve the sensitivity of transformer protection, ensure that the protection can be immediately disconnected in case of a fault, and partially solve the problem of non fault phase voltage rise caused by neutral point offset in ungrounded systems, limiting capacitor current.
