High Voltage Series (Filter) Hollow Reactance
ENHrH Series
Mainly used for 6KV~35KV (other voltage levels can be customized) power system connected in series with high voltage capacitor banks, which can effectively reduce the switching inrush current and inrush current frequency of capacitor banks, make it easy to select circuit equipment and protective capacitors, reduce the secondary harmonic voltage value on busbar, improve power supply quality, limit the flow of higher than the secondary harmonic current into capacitor banks, suppress higher harmonics and protect capacitors. It reduces the discharge current value from the perfect capacitor bank to the fault capacitor bank, reduces the inrush current multiple and frequency when the arc breaks down again, reduces the amplitude of operating overvoltage, and ensures the normal and safe operation of the device in the case of severe harmonics. The coil surface has anti-ozone ultraviolet protection layer, anti-aging, anti-all kinds of bad weather, can ensure continuous and stable work in the harsh environment in the field. |

Performance characteristics
●Adopt advanced computer software optimization technology, and can be designed according to the special requirements of users.
●Multi-layer parallel winding structure with ventilation duct between layers, natural cooling of air convection, good heat dissipation. The current is uniformly distributed in all layers, which better meets the requirements of dynamic and thermal stability.
●Due to the use of polyester film with excellent insulation and double glass-wrapped aluminium wire winding, it has higher electrical strength.
●The multi-layer circular simple winding structure is adopted with large longitudinal capacitance and uniform impulse voltage along the winding.
●Small cross-section wire winding is adopted, so eddy current and mud leakage magnetic loss are obviously reduced, and the quality factor is high.
●Aluminum alloy star-shaped boom structure, high strength mechanism.
●The coil is wrapped with epoxy resin and encapsulated with glass fibre impregnated with epoxy resin outside. The whole coil is cured at high temperature, with good integrity, low noise and short circuit resistance.
●Current shock.
●The surface of the reactor is coated with silicone organic paint which is resistant to ultraviolet radiation and can withstand harsh outdoor weather conditions.
●Installation mode can be three-phase vertical, or can be zigzag or zigzag. It does not need routine maintenance and runs safely and reliably.
