10kV high-low voltage prefabricated substation

1. Overview (application)

MRD-YB-10 Outdoor PackageSubstation is an outdoor combined distribution complete set apparatus used inthree phase, 50Hz, 6-10kV power systems. With reasonable design, the packagesubstation combines high voltage switchgear, transformer, low voltage electricapparatus into one or several cases organically, suitably used in city’sresidential areas, industrial and mineral enterprises, mineral sites, oilfields, wharves, airports as well as a temporal power supply equipment forcivil sites. 

1.      Working conditions

Altitude: not exceeding1000m

Ambienttemperature no higher than 45 centigrade, nor lower than -25centigrade

Outdoorwind speed not exceeding 35m/s

Relativehumidity daily average no greater than 95% at 25 centigrade and monthly averageno greater than 90% at 25 centigrade

Installationsite should be free from frequent severe vibration and shock, potential explosion,severe pollution and chemical corrosion

2.      Product features

There are automatic temperature controllingdevice, exhaust blower, heating and dew against device in the substation

Characteristic: Fastness, heatinginsulation, ventilation, good performance, guards against the micro-organism,moisture proof, nice looking, convenient maintenance, occupies little groundand so on.

At the high voltage side, use breakingswitch and current limited fuse as the protector for the transformer. When thecurrent limited fuse was fused, the three phase load breaking switch will cutoff. The high voltage side also can adopt the vacuum breaker as the protector

At the bottom of the transformer, the ponytruck can be installed, which can pass in and out freely for the inspection

The wiring and arrangement are various, interms of different environment and condition, it can adopt different structuresand covering material.
