SC(B)three-winding double split epoxy cast dry-type step-up transformer

Product introduction

Photovoltaic power generation as a clean energy production at home and abroad have developed rapidly,SC(B)  division series three-winding double epoxy cast dry-type step-up transformer is to  meet the growing  photovoltaic  power requirements,the production company 10kV,35KV dry-type transformers,based on the digestion and absorption of foreign advanced technology combined with domestic demand self-developed  products,the  product  has  asmall  size,lightweight,easy installation,and other advantages.

The meaning of model

Double Split epoxy cast dry-type transformers using high-quality materials,advanced manufacturing and testing  equipment is made according to strict production process.It is an electric strength,mechanical strength,heat-resistant high strength dry-type transformers.Products with high reliability,long life characteristics.Suitable for photovoltaic field.Depending on the use environment,you can configure a different level of protection.

Double Split epoxy cast dry-type transformers are designed to meet the practical application of technology and  has the following features:

1.Transformer was in line with local environmental conditions,such as ambient temperature and dust protection;   2.The transformer reaches the inverter rated power;

3.The transformer equipped with a temperature sensor,this signal may be input to the inverter;                              4.Transformer wiring in accordance with the system requirements;

5.Rated voltage secondary winding and the inverter output voltage is consistent;

6.The rated voltage and grid connection point of the primary winding of the power supply voltage matches the scope of the primary winding is at least within±2×2.5%range.

7.For each inverter,the transformer of this there is a separate,jisolated current of the secondary winding:

8.The short-circuit voltage transformer primary winding and a secondary winding between the UK meets thesystem requirements;

9.Transformer short-circuit voltage UK and split coefficient 9.The two secondary windings meets the system requirements.
