Combined transformer for wind power generation
Description:
Wind transformers are suitable for 35kv terminal power supply systems as power transformation, distribution, metering, control and protection devices. In addition to the transformer installed in the wind power transformer, the high-voltage side is also equipped with a four-position load switch or a two-position load switch, a backup protection fuse and a plug-in fuse. The low-voltage side can be equipped with control appliances, distribution appliances, and lighting according to user requirements. Repair transformer. Transformer oil is used as insulation and arc extinguishing medium.

Transformer oil is used as insulation and arc extinguishing medium.
This product meets the growing power supply demand of wind power. It is a series of products developed by ourselves based on the company’s conventional combination transformers, digesting and absorbing domestic and foreign technologies, and integrating customer needs. This product has the characteristics of small size, light weight, easy installation, low noise, Low loss, anti-theft, large overload capacity, full range fuse protection, simple maintenance and other features.
Features:
The internal configuration is highly reliable, economical and applicable. The high-voltage side is equipped with a load switch + fuse, which can reliably protect the transformer. The low-voltage side is equipped with a SOCOMEC isolation switch and a high-analytical fuse. A 2KVA station transformer is also installed; the main circuit scheme is simple and economical.
The high-voltage load switch and high-voltage fuse are placed in fully sealed transformer oil. The transformer oil is used as the insulating medium. The high-voltage outlet end adopts fully insulated silicone cable joints. It is truly full working condition, fully insulated, fully sealed, and maintenance-free, ensuring that it can be used in harsh environments. The service life is up to 20 years in the environment.
Imported high-ignition point oil is used as the insulation and cooling medium. There is no need to filter or change oil during the service life. The seals use high-performance imported rubber beads, which have the same lifespan as the equipment.
The outer door of the cabinet adopts a unique labyrinth sealing formula and is equipped with highly elastic and long-life sealing strips. The ventilation holes are equipped with dust-proof facilities, which can effectively prevent wind erosion caused by sand, snow, etc., and the protection level is IP44 .
Can be used in ring network. It can also be used in terminals for easy conversion.
Low damage, low noise, superior performance.
The box adopts anti-theft structure
Low temperature rise, strong overload capacity
