变压器中性点接地电阻柜可靠性高，一般不需要专门停电维护，建议利用站内主变或母线停电检修的机会进行检查维护，检查维护时必须严格执行安全操作规程和安全工作规程； 将电阻柜从系统上断开； 打开柜门，直接查看箱内有无异常；进行清洁处理。
The neutral grounding resistance cabinet of the transformer has high reliability and generally does not need special power outage maintenance. It is recommended to use the opportunity of power outage maintenance of the main transformer or bus in the station to carry out inspection and maintenance. During inspection and maintenance, the safety operation regulations and safety work regulations must be strictly implemented; the resistance cabinet shall be disconnected from the system; the cabinet door shall be opened to directly check whether there is any abnormality in the cabinet; the cleaning shall be carried out.
变压器中性点接地电阻柜采用优质不锈钢或不锈钢电热金属材料，具有电导率高、温度系数高、耐腐蚀、耐高温、抗氧化能力强、抗拉强度高及阻值稳定等优良特点，产品运行安全可靠。在中压配电系统中，如果变压器为三角形接法，则需加装Z型接地变压器，以便为系统人为引出中性点，以加装中性点接地电阻柜。
The transformer neutral grounding resistance cabinet is made of high-quality stainless steel or stainless steel electrothermal metal material, which has high conductivity, high temperature coefficient, corrosion resistance, high temperature resistance, strong oxidation resistance, high tensile strength, stable resistance value and other excellent features, safe and reliable operation of the product. In the medium voltage distribution system, if the transformer is connected in a triangle way, it is necessary to install a Z-type grounding transformer so as to manually lead out the neutral point for the system and install a neutral point grounding resistance cabinet.
