Product Description
Transformer cabinet is at the bottom of product, main body is in it, there is a silicon rubber composite insulation bushing or high strength porcelain bushing at the middle and primary terminals are at top both sides of product.
A SF6 gas density controller is equipped on the transformer cabinet; it can monitor the SF6 gas pressure in-line. There is a pressure-relief device on the top; the rupture (relief) pressure is 0.7 MPa without oil or explosion risk, and it is free-maintenance.
Main body is inside the cabinet, use the composite insulation of polyester film and SF6 as interlayer insulation, so it has high strength insulation. Coil uses single-staged tower structure, so it has a good shock resistant performance.
Product shell is carried out hot galvanizing or uses cast aluminum alloy, all components including stainless steel fasteners and nameplate etc work in outdoor for long time without rust.
Primary terminal block uses cast aluminum part, the static test load it can bear is no less than 3000N.
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 conve-Introduction to Structure Symbol Explanation Antipollution Class W2 or W3 Rated Voltage Grade Measurement Coil and Protection Coil Being Separate With Residual Voltage Coil Gas-insulation Single Phase Voltage Transformer nient for operations such as plug-in, pull-out and wiring etc. Optimal Electrode shielded structure improves internal and external field distribution of the product. It has an excellent insulation property. Partial discharge test is carried out under power frequency test voltage.
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%.
High voltage coil is made of imported polyester film and conducting wires with high insulation strength and stable performance; use imported automatic winding equipment to complete the wire winding and the wrapping of interlayer insulation automatically according to entered instructions.
It can be designed and made with three coils (one primary coil, one secondary coil and one residual voltage coil) or four coils (one primary coil, two secondary coils and one residual voltage coil) according to the requirement of customer.
Integrated design is reasonable; it shows capacitive character under certain voltage
