Product Introduction:

The BYF1-40.5 type two-position oil-immersed load switch is suitable for integrated transformers with AC frequencies of 50Hz and 60Hz, and a rated voltage of 35kV. It is a load switch specially designed and manufactured by our company for the increased voltage class of domestic integrated transformers.

The load switch adopts a two-position structure. It uses transformer oil as the insulation and arc-extinguishing medium, with spring energy storage and three-phase linkage. It can accurately and quickly open or close the rated load current and can withstand short-term fault current under specified conditions. The contact system of the switch adopts a double-break floating contact bridge. The moving and static contacts have good contact performance, low resistance, and strong current-carrying capacity. The unique structural design gives the contact system an excellent electromagnetic compensation effect, greatly improving its fault resistance under short-circuit conditions.

The load switch has two positions: open and closed. It is operated by rotation: clockwise to close and counterclockwise to open, with a rotation angle of 90°. According to different power grid needs and configurations, it can be used as a control device for terminal-type integrated transformers or three load switches can be used to form a control device for ring network type integrated transformers. The load switch can also be equipped with an auxiliary travel switch and an electric operating mechanism to suit various types of transformers. Customers can choose corrosion protection classes such as C3, C4, C5, etc., according to design requirements.
