Answer: The installation form of outdoor transformer installation: outdoor transformers installed in the open air are also called outdoor transformers, which can be divided into platform (ground) installation and pole (pole) installation.

1) There are poles installed but the capacity should not exceed 315KVA; the distance between the rural installation transformer and the ground is not less than 2.8 meters, and the city installation transformer is not less than 3.5 meters from the ground;

2) The capacity of the transformer installed on the ground transformer is not limited.

General requirements for outdoor transformer installation:

(1) The distance between the outer profile of a transformer of 10kV and below and the surrounding fence or fence should consider the convenience of transformer transportation and maintenance, and the distance should not be less than 1m; a distance of more than 2m should be left in the direction of operation; if metal is used Fences, metal fences should be grounded, and warning signs should be hung on obvious parts;

(2) The height of the transformer pier installed on the ground is generally 0.5m, and a fence of no less than 1.7m should be installed around it, and warning signs should be hung at obvious places;

(3) Transformers of 315kVA and below can be installed on poles. The bottom should not be less than 2.5m from the ground; the live part should not be less than 3.5m from the ground;

(4) The transformation platform on the column should be stable and firm. The waist fence should be wound with Φ4.0mm galvanized iron wire more than 4 times and the number is even. The iron wire should not have joints and should be tightened after winding. The distance between the waist fence and the live part should not be less than 0.2 m;

(5) The installation position of the secondary fuse on the pole and the ground transformer should meet the following requirements: 1) If there is an isolating switch on the secondary side, it should be installed between the isolating switch and the low-voltage insulator, or using a fuse as an isolating switch; 2 ) If there is no isolating switch on the secondary side, it should be installed on the outside of the low-voltage insulator, and use an insulated wire to bridge the insulated wire at both ends of the fuse;

(6) Insulated wires should be used for all high and low voltage leads on poles and above-ground transformers; (7) When the transformer is installed near a factory building with general dust removal and exhaust outlets, the distance should not be less than 5m;

(8) The basic track of the transformer should be level, and the gauge and track should be matched. For transformers equipped with gas relays, the top plate should have a 1%-1.5% rising slope along the airflow direction of the gas relay (the manufacturer’s regulations do not Except for those who need to install a slope), and install a wheel stopper.
