Special box-type substation for solar photovoltaic power generation
Special box-type substation for solar photovoltaic power generation
Model: MSK-1000KW
Details

     This is tailored for megawatt photovoltaic power plant. The system integrates a MV transformer (boosting transformer), AC power distribution equipment, monitoring device, communication device and others in a single mobile room that improves system safety, reliability, efficiency, power generation volume. It is the best solution for megawatt photovoltaic power plant.

Inverters and PV step-up transformers on the large photovoltaic power station

should be installed separately.Line connection,construction and installation on

 site are complex. Developing products of integrated PV substation in order to 

meet the requirement transforming from scattered construction to factory

 pre-installed integrated manufacture.

the step-up transformer unit, inverter unit and its auxiliary components are integrated together.

There are mThe main circuit breaker switch any advantages such as strong complete ,

 less occupation of the land, reducing line loss, shortening the period of sending, 

easy installation, reliable operation and less investment,etc.

1.The cost of foundation construction is low and covering less area.

2.he cost of a transformer and a inverter connecting a cable and construction is low 

and theline loss is low.It is benefit to improve construction quality.

3.The cost of the main circuit breaker switch which connects the transformer 

with the inverter is low.

4.The time of the secondary circuit debugging is short.

5.The transformer has many advantages such as low loss,

low temperature rise,strong ability to resist sudden short circuit and protection.

6.The design of inverter room is equipped with reliable ventilation,radiator and

 measures of preventing condensation. 

7.The inverter room is equipped with complete fire fighting devices.
