10kv box-type substation is suitable for mines, factories, oil and gas fields and wind power stations. It replaces the original civil power distribution house and power distribution station and becomes a new set of transformer and distribution equipment. So what is the technical standard for 10kv box substation reference? The following is the analysis of the latest version of 10kv box substation technical standards.

The budget calculation of 10kv box substation is quite complicated, which touches on the problem of transformer accounting and selection. In general, about professional designers, can according to the parameters of the box-type substation, from a brief formulation operation to follow a series of data, and then select from these data, combined with the operation principle of transformer and internal parameters to choose corresponding transformer, the specification is not enough or to avoid selection is too high, the transformer can fit the requirement of the box-type substation.
10kv box substation service conditions:
A. use location: outdoor
B. Altitude: ≤1200m
C. Ambient temperature:
Maximum temperature: 40℃
Average temperature of the hottest month: 30℃
Maximum annual average temperature: 20℃
Minimum temperature: -40℃
D. relative humidity
At 25℃, the relative humidity of air does not exceed 95%, and the monthly average does not exceed 90%.
E. Installation environment
The installation environment should be free from obvious pollution, explosion, corrosive gas and dust, and the installation site should be free from strong shock. The ground acceleration ag induced by the earthquake is lower than 3m/s2 in the horizontal direction and 1.5m/s2 in the vertical direction.
F. The waveform of the power supply voltage is approximate to the sine wave.
G. Three-phase power supply voltage should be approximately symmetrical.
