  • Product: Intelligent integrated box substation
  • Rated capacity: 30~3150kVA
  • Frequency: 50/60Hz
  • Primary voltage: 6/10kV
  • Secondary voltage: 0.4/0.69kV

Purpose
10kV intelligent integrated box substation is an outdoor distribution system which contains HV switch, transformer and LV switch. The user including 6-10KV ring network, terminal user, industrial areas, residential areas, commercial centers, parks, railway stations, airports, oil fields, temporary facilities and other outdoor space.


Characteristics
1. It was compact, large capacity and smart.
2. High and voltage protection fully, safe and reliable operation, easy maintenance.
3. Smart, low investment, short production cycle and easy to movie.
4. Unique structure, double honeycomb structure( composite board), housing firm, insulation and ventilation, artistic, high degree of protection, the material of enclosure including stainless steel alloy, aluminum, cold-reduced sheet, color plate, tiling, paste wood, new environmental protection materials, surface watercolor and so on.
5. Universal forms, including general type, villas type, compact type and so on.
6. It could be equipped with automation terminal (FTU) in high-voltage ring main unit to realize test of short-circuit and single phase earth fault with four remote function, easy upgrade.


HV side:
Intelligent substation integration generally adopt high voltage load switch---fuse combination protection, if one phase fuse is blown, three-phase linkage trip, there are a number of types to choose as pressuring gas, vacuum, sulfur hexafluoride and so on, which could realize automation upgrades, high-voltage current-limiting fuse with striker, reliability, breaking capacity, the main technical parameters as follow


LV side:
The low pressure side of the main switch with universal formula or smart circuit breaker, selective protection; outlet switch selection of new small molded case switch, arcing short circuits of up to 30; intelligent automatic tracking reactive power compensation device, there are contacts and non-contact switching two kinds of ways for users to choose.


Transformer:
Intelligent selection of low loss integrated substation, oil-immersed, sealed S9, S10, S11 series transformer can also be used resin insulation or NOMEX paper insulation environmentally friendly dry-type transformers, the bottom with trolley, transformer can easily access.
