Outdoor Vertical Oil Immersed Current Transformer 230KV Air Permeable Sealing

OIL-IMMERSED VERTICAL CURRENT TRANSFORMER (LB)

◎ LB6-110 current transformer is an oil-immersed fully sealed insulation structure, the primary winding is "U"-shaped, the body is fixed at the bottom of the box, the main insulation is capacitive oil paper insulation, and high-voltage cable paper is wrapped around the primary winding On the upper side, there are a number of capacitive screens in between, the inner screen is connected to a high potential, and the outer screen is reliably grounded.

◎ The upper part of the fuel tank is equipped with a porcelain sleeve, and the primary outlet terminal is on the top of the porcelain sleeve. The series and parallel connections are external exchange devices, that is, the exchange can be performed outside the porcelain sleeve.

◎ The stainless steel expander is used as the oil compensation device to ensure the quality of the oil. The oil level indication of the product is indicated by the eye-catching displacement of the upper window of the expander.

◎ The product can be equipped with 4~6 secondary windings, and the secondary measurement winding made of microcrystalline alloy with high magnetic permeability can ensure the measurement accuracy to 0.2 or 0.2S, and the measurement of 2×600A and above current transformer The secondary winding of the stage has taps to achieve two current ratios.

◎ The secondary outlet box is integrally cast in aluminum alloy, with a dustproof, waterproof, and air-permeable sealing structure

◎ The connection between the product components adopts argon arc welding, and the assembled body is filled with high pressure nitrogen for leak detection, which fundamentally solves the problem of oil leakage of oil-immersed products.

◎ The shell, base, and junction box are all made of aluminum alloy casting. The expander and nameplate are made of stainless steel, and all exposed parts will never rust.

◎ The product is maintenance-free.
