DL/T537-93 order 6 to 35 kv box substation technical conditions”

Conditions of use

ASL not exceeding 1000m;

Ambient temperature: – 35 ℃ ~ + 40 ℃;

Relative humidity: day average no greater than 95%, the monthly average no greater than 90%;

Mounting ambicnt: no fire and explosion danger, chemical corrosive gas and well ventilated place, the ground tilt Angle is not more than 3 °.

Function and characteristics of the

Fully insulated, fully sealed, free or less of maintenance and reliable to ensure personal safety;

Compact structure, with the volume being only 1/3-1/5 of European transformer with the same capacity, and low height;

Adopting box-type structure to avoid oil pollution in the transformer oil tank; adopting double fuses on the HV side for full range protection, thus greatly reducing the cost;

Able to be used as ring net or terminal and the cable head can be plugged and unplugged in case of 200A load current;

Adopting honeycomb double sandwich composite board for the box, thus endowing functions of temperature isolation and heat dissipation;

Equipping electronic phase-loss protector on the LV side to quickly disconnect the main switch when abnormal voltage occurs in the system;

Equipping oil-immersed load switch or SF6 load switch which can be electrically upgraded on the HV side, thus to lay a foundation for the automation of distribution network;

Adopting oil-immersed S9 or S11 series transformer with better performance.
