Product Description

SF6 Gas-insulated Inverted Current Transformer
 

Introduction:
LVQB series current transformer has an inverted structure with SF6 gas insulation (Please see the figure). It is
connected in series with electric energy measurement, measuring, and relay protection functions.  Primary coil
has a through-type conducting rod structure with good dynamic and thermal stability; its maximum
thermal current can be up to 63kA/3s (when primary coil is connected in series).

Primary coil passes through the center of secondary coil without flux leakage. Measurement precision can be up
to 0.1 and 0.2S grades. Secondary coil is fixed in an aluminum shielded-case by casting organic materials;
measurement and protection circuits cannot be damaged by insulation breakdown.
Seal ring is made of imported fluorocarbon silicone rubber, it is suitable for using in the area where there is
greattemperature change or the environmental temperature is extreme. The leakage rate per year is less than
0.5%. Product performance keeps changeless after severe transporting test. Use an aluminum alloy cast case,
all components including the base, connection box, stainless steel expander, andnameplate etc do not rust
forever. A density meter is installed on the base, this meter can show the gas pressure and density in the
transformer (The showvalue is turned to be the internal gas pressure at 20 automatically). A signal for refilling
gas is sent out when the pressurein the transformer drops down to the alarm pressure
