Current Transformer

� LVB (T) series current transformer has an inverted structure with oil-immersed paper insulation (Please see the left figure).

It is connected in series with electric energy measurement, measuring, relay protection and transient 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 0.1and

0.2S grades.

� Secondary coil is fixed in an aluminum shielded-case by casting organic materials; secondary measurement and

protection circuits cannot be damaged by insulation breakdown.

� Optimal capacitor screen bushing is made of a complete piece of imported broadsheet cable paper; it is coiled by an

automatic wrapping machine which is controlled by a computer with high performance. It has a technological de-centrality

and an excellent insulation property. Partial discharge test is carried out under power frequency test voltage.

� Use the automatic vacuum drying treatment system produced by LEYBOLD in Germany, carry out pressure-changing

vacuum drying treatment and oiling after a product is assembled completely, and all insulation materials are imported from

foreign countries. All these ensure that the dielectric dissipation factor of complete product tan_ is less than 0.3%.

� External insulation uses a porcelain cover with high strength, optimal surface field intensity together with lower field

intensity of internal bushing make the porcelain cover avoid explosion.

� Secondary outlet box is a complete structure by casting the aluminum alloy; its sealing structure meets the requirement

of IP55, which is dust proof, water proof and air permeable; secondary terminal for wiring uses Phoenix special terminal; it

is more convenient for operations such as plug-in, pull-out and wiring etc.

� Connection between components uses argon-arc welding, fill in high pressure nitrogen to detect leakage after assembly

is complete, so oil penetration and oil leakage caused by oil-immersed products are resolved at root.

Use an aluminum alloy cast case, all components including the base, connection box, stainless steel expander, and

nameplate etc do not rust forever.

� It is light and handy with a small volume and light weight.

� This product is free-maintenance.

silicon rubber avoid electrical erosion.

� Porcelain bushing shell with high-strength.

� Secondary outlet box is a complete structure by casting the aluminum alloy; its sealing structure meets the requirement

of IP55, which is dust proof, water proof and air permeable; secondary terminal for wiring uses Phoenix special terminal; it

is more convenient for operations such as plug-in, pull-out and wiring etc.

� Seal ring is made of imported fluorocarbon silicone rubber, it is suitable for using in the area where there is great

temperature 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, and

nameplate 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 show

value is turned to be the internal gas pressure at 20� automatically). A signal for refilling gas is sent out when the pressure

in the transformer drops down to the alarm pressure.

GIS Gas-insulated Voltage Transformer

Voltage transformer matched with GIS is used for SF6

close combined apparatus; it is connected between the

phase and ground. It uses SF6 gas as main insulation, and

uses polyester film, which is used for interlayer insulation,

as additional insulation.

Main components of transformer

an instruction plate and a secondary terminal box on the

metal shell. The shell body is formed by welding steel

plates and hot galvanizing, all connecting bolts uses stain-

less standard parts, they can work in outdoor place for long

time, and do not rust forever. A metal rupture disc is

installed on the base. If a high energy discharge occurs in

it, the rupture disc will break to relief pressure, so the safety

of product is improved.
