Brief Introduction
This series of Current Transformers include the products with the type of LVB(T)-150W2;LVB(T)-161W2(LVB(T)-170W2); LVB(T)-220W2(LVB(T)-252W2);LVB(T)-230W2 (LVB(T)-245W2);LVB(T)-330W2(LVB(T)-363W2)LVB(T)-500W2 (LVB(T)-550W2) etc., which can be used for electric measurement and relay protection in the electric power system with a voltage of 150 ~ 550kV and freguency of 50 ~ 60Hz. The products are in accordance with the requirements of the standard GB20840.1,GB20840.2 "Current Transformers"&lEC61869-1, IEC61869-2"Current Transformers".
Characteristics
1.Be sealed up limitedly, the seal components are not exposed to alr, with better sealing pertormance and longerservice life.
2.With large dynamic current and short-time thermal current.
3.With transient protection winding, which can meet the reguirements of high-capacity in the electric powersystem and reclosing operation.
4.Oil conservator made by the anti-corrosive aluminium alloy, can eliminate the partial whirlpool heat, and be rustless
5.Porcelain bushing made by hiah strenath porcelain, and spliced with oil conservator in integral, with compactstructure, beautiful appearance and high mechanical strength.
6.With developed main insulation structure, having better insulation performance and higher reliable technology
7.Oil draining valve has been applied syringe to take oil sample, which can ensure the precision of transforme oil test.
8.With advanced drying technique of profiling heat conduction, medium heat as well as high degree vacuum drying adopted, insulation always stays its original state, all of which enable a more reliable performance of product characterized by its small increment which is below 0.05% and low dielectric loss which is below 0.3%under the applied voltage of 10kV.
9.With progressive oiling technique, heating hermetical oiling technology adopted, partial discharge is slight.
