[110KV current transformer]LCWD2P-110 High Voltage Current Transformer

2026-6-20 11:25:20

The LCWD2P-110 current transformer is a porcelain box type oil paper insulated "8" - shaped structure. Wrap the secondary coil on the circular iron core, combine the three secondary windings together, and wrap them with insulation. Then wind a primary coil through its window, and wrap insulation around the primary coil. The primary and secondary coils form an "8" shape. Two sets of identical coils can be wound in one go, and two current ratios can be obtained by series or parallel connection of the output terminals on the oil storage tank (small current in series connection and twice the primary current in parallel connection). 1�� The secondary coil (body) is inside the porcelain sleeve and filled with transformer oil. The device body is fixed on the base, and the secondary output is sealed and led out by a small porcelain sleeve, and fixed on the base for wiring. The output end of the primary coil is also sealed and fixed on the outer wall of the oil storage tank with a small porcelain sleeve, making it easy to connect in series or parallel. The oil storage tank is equipped with a corrugated metal expander, which is also sealed. When the transformer oil of the transformer expands or contracts due to temperature changes, the volume of the metal expander also expands or contracts, maintaining a slight positive pressure inside the transformer. Therefore, it can prevent the external atmosphere from entering the transformer and causing the insulation of the transformer to become damp. The transformer is a fully sealed structure that can prevent moisture from entering and isolate the transformer oil from contact with the outside world, delay the aging of the transformer oil, and thus extend the life or maintenance period of the transformer.
