today, Shenzhen Kengzi transformer installation company analyzes the selection of distribution transformer installation location. The distribution transformer has certain requirements for the installation position

(1) consider the installation position from the perspective of power distribution line. The transformer is installed in the load center or not far away from the center of the power supply. When it is put into operation, the loss of the line is less, and the quality of the power supply voltage can be guaranteed

(2) from the perspective of installation site. Distribution transformers should be avoided in places with many trees or vast waters. The soil resistance at the installation position of distribution transformers is small and the grounding performance is good, but when it doesn't rain, the soil can ensure a certain humidity without much

(3) consider from the planning and fire protection requirements. The installation position of distribution transformer meets the requirements of the development plan, and generally, the forum should not be changed within three to five years; At the same time, it should meet the requirements of fire protection, and the traffic and transportation are quite convenient, which is convenient for installation and maintenance or power failure and fire extinguishing in case of power accidents

(4) consider from the installation position. If the transformer is installed outdoors, it can be divided into pole installation and floor installation. Among them, pole installation cannot be installed in the following three places ≤ 500mm, which will leave a rich, warm and regretless youth memory of Yucheng bioengineering Utilization Technology Research Institute of Southeast University

① for poles with many household lines connected to low-voltage overhead lines, transformers are generally required to be installed independently. Sometimes under special circumstances, it is normal to separate several outgoing lines, but not more than three

② distribution transformers cannot be installed on corner poles, branch poles, poles of existing transformers or switches on columns, high-voltage downleads and cable poles

③ it is not easy to patrol, inspect, measure the load and detect the pole lifting the transformer, and the transformer cannot be installed; At the same time, a small fence should also be set up when installing on the pole

when installing on the ground, it is not allowed to choose places that are inconvenient for installation and maintenance, such as under trees, mountain tops, depressions, Xishang places, intersections of major traffic roads, or places with large crowds, such as markets, shopping malls, etc. at the same time, it is required to set fences, which are generally not less than 2m high. Pay attention to avoid the minefield during outdoor installation, but still install outdoor lightning protection devices

(5) consider from the specific installation position. If the transformer is installed indoors, it should be ventilated and shady. If it is a dry-type transformer, it can be installed in a corner indoors. If it is an oil transformer, it should be placed in the middle of the room as far as possible, but it should avoid the access to maintenance. Supply fan shall be installed in the installation room
