Sf6 Gas-Insulated Inverted Current Transformer/Protect Current Transformer

Product Name: Sf6 Gas-Insulated Inverted Current Transformer/Protect Current Transformer Model NO.: LVQB-66W3 Brand: Ville Shape of Core: Ring Frequency Characteristics: High Frequency Usage: Single-phase Transformer Certification: ISO9001-2000, ISO9001 Winding Type: Separated Winding Transformer Cooling Method: Dry-type Transformer Core: Core-type Transformer Phase: Single Application: Power, Electronic, Instrument, Lighting, Rectifier, Audio Trademark: VILLE INDUSTRY Transport Package: Wooden Cases Specification: IEC Origin: Ningbo China HS Code: 8504 Product Description SF6 Gas-insulated Inverted Current Transformer/Protect CurrentTransformerTechnical parameters:LVQB series current transformer has an inverted structure with SF6 gas insulation (Please see the figure). It isconnectedin 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 maximumthermalcurrent 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 upto 0.1and 0.2S grades.Secondary coil is fixed in an aluminum shielded-case by casting organic materials; measurement and protectioncircuitscannot be damaged by insulation breakdown.Optimal Electrode shielded structure improves internal and external field distribution of the product. It has anexcellentinsulation property. Partial discharge test is carried out under power frequency test voltage.There are two types of external insulation bushing for customers: they have excellent explosion-resistant andshockresistantbehaviors.External bushing uses silicon rubber umbrella type apron reinforced by glass fiber. Optimal external surfacefield makessilicon 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 therequirementof IP55, which is dust proof, water proof and air permeable; secondary terminal for wiring usesPhoenix special terminal; itis 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 isgreattemperature change or the environmental temperature is extreme. The leakage rate per year is less than0.5%.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 sentout when the pressurein the transformer drops down to the alarm pressure.Note: 1 The parameters in the table are not changeless; the Company reserves the right to change them.2 When the parameters required by the customer are different from that in the table, they can be negotiatedaccording to therequirement 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.Our Best Service For You1.Pre sale servicea.make technical solutionb.send quotation, technical data sheet and drawingc.prepare power transmission plan, testing plan and shipment plan2.In sale servicea.supervise the manufacturing schedule totally in accordance with the planb.send photos to customer during every manufacturing process(hold point)c.inform the customer one week before testing.3.After sale servicea.installation and commissioning, training the workersb.quick response within 12 hours any timec.provide 12 months guarantee period normally.FAQ For You1.
