LVB-110 Series Inverted structure with oil-immersed paper insulation ofIntroduction:
LVB (T) series current transformer has an inverted structure with oil-immersed paper insulation (Please see the
It is connected in series with electric energy measurement, measuring, relay protection and transient protection
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.Symbol Explanation
Note: 1 The Company reserves the right to change the parameters in the table.
2 When the parameters required by the customer are different from that in the table, they can be negotiated
according to the requirement of the customer.
3 There are several current ratios for one-time switch of the transformer.
4 We also can provide with products which meet the requirement of IEC and ANSI.Outline and Dimensional Drawing
