Combined Transformer for Windpower Generation
Combined transformer for wind-power generation combines step-up transformer, switchgear, fuse, tapping switch and relevant auxiliary switch. HV switch and fuse are installed in oil tank. The overall dimention is small. According to the structure and component of the substation, it could be divided into total insulated divided enclosure product and common enclosure product with HV pocelain outling bushing. The product satisfies the IEC1330 and other relevant standards.
2 Service and Installation Conditions
Ambient temperature: -40℃~+40℃
Moisture: Daily average≤95%, Monthly average≤90%
Wind speed: Outdoor wind pressure≤700Pa (34m/s)
Seismic resistance: Horizontalacceleration≤0.4m/s2, Vertical acceleration≤0.15 m/s2
Ambient temperature: The ambient environment should be without obvious pollution, such as corrosive or flammable gas or steem, and etc. The installation site should be without severe vibration.
Additional consultation between the user and manufacture should be needed, if the switchgear is to be operated in the conditions not in conformity with the above ones.
