Product Description

General Introduction

Reactor is a kind of inductive element, which is a device used in power system because of its inductance characteristics. The reactor plays the role of reactive power compensation, current limiting, smoothing, filtering, damping, and shifting in the circuit. It is a commonly used and important power equipment in the power system, especially in the parallel compensation device, the series reactor is mainly to reduce the closing inrush current, improve the voltage waveform of the power grid, and suppress the harmonic amplification and limit the damage of the capacitor to the capacitor.
Dry-type reactors are insulated by epoxy resin, which have the characteristics of high heat resistance, flame-retardant, explosion-proof, maintenance-free, impact resistance, long life, easy installation and use, and are widely used.
At present, we can design and produce 6kV~110kV dry-type air-core series reactors, and 10kV and 35kV dry-type iron-core reactors. And obtained the type test of the Suzhou Academy of Sciences. our main product types such as:
1. Series reactor: It is connected in series with the capacitor in the parallel capacitor compensation device to suppress the harmonic current and limit the closing inrush current.
2. Current-limiting reactor: The current-limiting reactor is connected in series to the system to suppress the short-circuit current and limit the short-circuit current within the allowable range when the system fails.
3. Filtering reactor: used in series with the filter capacitor bank to form a tuning loop to filter out specific high-order harmonics to achieve reactive power compensation of the power system and limit the surge current when the capacitor bank is put into the power grid.
4. Parallel reactor: connected in parallel to the power system, through the main transformer to the system to deliver inductive non-function, used to compensate the capacitive current of the transmission line, prevent the light load line terminal voltage from rising, and maintain the voltage stability of the transmission system.
