Strictly design, produce and test in accordance with the general technical specifications of the bidding documents of 500kV/70Mvar single-phase shunt reactors of State Grid Corporation and the corresponding national standard GB/T 23753-2009 "Technical Parameters and Requirements of 330kV and 500kV Oil-immersed Shunt Reactors":

     1. The coil adopts internal screen continuous type and transposition wire;

     2. The iron core adopts the yoke structure on both sides of the single core column, and the air gap of the core column is aluminum ceramic cushion;

     3. The iron core adopts five elastic pressing and stopping devices;

     4. The body insulation adopts a thin paper tube and a small oil gap structure, with an all-round magnetic leakage shielding system;

     5. Other special requirements.

1. The reactor is the largest-capacity product in the 35kV voltage level. To reduce vibration, this product is designed with a three-core yoke structure on both sides. To reduce the magnetic leakage area, the coil adopts a large reactance height/small radial structure.

2. The product uses a magnetic leakage shielding system, that is, magnetic shielding is provided at the upper and lower ends of the winding, and the magnetic shielding of the box wall is provided on the front and rear side walls of the winding. At the same time, the thick iron yoke structure is adopted, and the key structural parts are made of high strength Magnetic stainless steel materials and other measures to prevent local overheating of structural parts due to magnetic leakage.

3. In terms of reducing vibration and noise, the iron core adopts seven elastic pressing devices, the upper and lower yokes adopt a clamping screw clamping structure, the side yoke adopts a steel pulling belt and a clamping screw clamping structure, and the body and the fuel tank are positioned at multiple points. To reduce the natural frequency of the core.
