1.需不需要安装接地变，变压器星接时可以直接使用电阻接地系统，变压器为角接时，可以安装独立设计成接地变，中性点电阻与之连接使用。
1. There is no need to install the grounding transformer. The resistance grounding system can be directly used when the transformer is star connected. When the transformer is angle connected, it can be installed and independently designed as the grounding transformer, with the neutral point resistance connected to it.
2.安装位置是户内还是户外。户内：柜体顶部可设计成平顶，户外：柜子顶部设计成倾斜，需要加防雨檐，防止因为下雨天气造成柜内进水。
2. Whether the installation location is indoor or outdoor. Indoor: the top of the cabinet can be designed as a flat roof, outdoor: the top of the cabinet is designed as a tilt, and rain eaves need to be added to prevent water from entering the cabinet due to rainy weather.
3.根据用户需求选择接地电阻柜的进出线方式，一般采用上进上出，和上进下出等等。
3. According to the user's needs, select the incoming and outgoing ways of the grounding resistance cabinet, generally using the up in and up out, up in and down out, etc.
4.接地电阻柜一般重量在300KG及以上，柜体顶部需装有吊环，便于吊装。
4. The general weight of the grounding resistance cabinet is 300kg or above, and the top of the cabinet body needs to be equipped with lifting rings for easy hoisting.
5.安装电阻柜智能监测保护装置，检测接地电阻柜运行，可记录单相接地时间，接地电流大小，柜内的温湿度，并能记录接地次数，同时装有通讯接口。
5. Install the intelligent monitoring and protection device of resistance cabinet to detect the operation of grounding resistance cabinet, record the single-phase grounding time, grounding current, temperature and humidity in the cabinet, record the grounding times, and install the communication interface.
