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 6kA/s (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.%. 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. 7 8
