Outdoor high voltage substation 11KV 15KV 33KV

Description

11KV 15KV 33KV Environmental protection, energy saving and low noise outdoor high voltage substation

The description OF Outdoor high voltage substation

Outdoor high voltage substation is also called box type substation,  description Ac metal closed type shift switch cabinet is a three-phase ac 50/60Hz indoor device metal closed switch equipment.  It Is generally used in power plants.

Substation system rated voltage 35kV, rated maximum current 2000A maximum voltage no more than 40.5kV single bus or single bus sectionalized sets of distribution equipment.

This switch device meets the requirements of DL/ t404-91, IEC62771 and other standards, and has the functions of preventing wrong operation of circuit breaker, pushing and pulling handcart with load, grounding line, power transmission with grounding line and accidental charging interval (referred to as “five precautions”).

Box type substation is suitable for residential district, urban public change, bustling downtown, construction power and so on. Users can choose box type change according to different use conditions and load grade.

Since the advent of the box substation, it has developed very rapidly. In developed countries, 70% of the distribution transformers have been developed, and the United States has accounted for 90%.

The rapid development of China’s urban modernization and the renovation of urban distribution network will be widely applied.environment condition. Box type substations are used in high-rise residential, luxurious villas, square parks, residential areas, small and medium factories, mines, oil fields, and temporary construction electricity and other places to accept and distribute electricity in the distribution system.

Main features:

4. Humidity: daily average ≤95%, monthly average ≤90%;
5. Pollution degree:IP54
6. Earthquake intensity: 8 degree;
7. Occasions without fiercely shake and corrosiveness, as well as without flaming and explosive matter, the verticality is no more than 3 degree.

Main Components:

MV Switchgear
· MV secondary switchgear including incoming feeder, outgoing feeder and transformer feeder
· The MV can be SF6 gas insulated type Ring main unit or air insulated switchgear
· In some cases – there is no MV switchgear, the MV cable is mounted directly on the transformer

Transformer
· Oil immersed hermetically sealed or Dry type transformers can be installed
· Transformer bushings can be located on top or side of transformer as per customer needs
· Wide range of transformer capacities up to 3500 kVA
· SafePack is designed to allow simple and easy transformer installation on site or integrated into the SafePack in the factory

LV Switchboard
· Incoming feeder options can be direct connected, circuit breakers, fused disconnectors or Load Break Switches
· The LV busbar rating depends on the transformer rating
· Various number and ratings of outgoing feeders depending on transformer size and customer needs
· Equipment for metering, measuring and control available
