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。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。
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. 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.
2、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。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。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。
2. According to the user's requirements, 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. 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 to facilitate
hoisting. The intelligent monitoring and protection device of resistance
cabinet is installed to detect the operation of the grounding
resistance cabinet. It can record the single-phase grounding time, the
grounding current, the temperature and humidity in the cabinet, the
grounding times, and the communication interface
