Filter Reactor: The front end of the filter compensation capacitor in the reactive compensation system, suppresses harmonics in the power grid and ensures the normal operation of the filter compensation capacitor. It is connected in series with the filter compensation capacitor and in parallel in the power grid containing harmonics to eliminate the harmonics of a certain frequency (such as the 3rd, 5th, 7th, 11th, 13th, etc.) in the power grid and protect the equipment in the power grid.

The main functions of the filter reactor are:

1. It is used to eliminate the harmonics of a certain frequency (such as the 3rd, 5th, 7th, 11th, 13th, etc.), or to protect the filter compensation capacitor to avoid damage and explosion caused by harmonic current, and to ensure the normal operation of the reactive compensation device. It is a reactor product with dual functions such as harmonic suppression and reactive compensation.

2. In the parallel resonant circuit, the reactor also plays a role in suppressing large alternating currents to prevent the large alternating currents generated in the inverter from damaging the rectifier thyristor.

• The reactor is divided into three-phase and single-phase, uniform iron core dry type;
• The iron core is made of high-quality cold-rolled silicon steel sheets, which are punched and sheared by high-speed punching machines, with small burrs, regular and uniform, neat and beautiful sheets, ensuring the performance of low temperature rise and low noise of the reactor;
• The coil is made of high-quality insulated wires and wound by special machines, with the advantages of good flatness and beautiful appearance;
• During the assembly process of the reactor, all clamps are treated with anti-corrosion, and key clamps are made of non-magnetic materials. After a series of processes such as pre-baking-vacuum dipping-hot baking and curing, the electrical coil and the iron core are firmly integrated, which greatly reduces the temperature rise and noise during operation, effectively improves the quality factor of the reactor and reduces the effect of harmonics;
• The outer dimensions of the reactor refer to the standard cabinet dimensions, with small size and convenient wiring, which greatly saves the user's cabinet cost investment.
• Performance parameters
• It can be used for 400V and 660V systems.
• Rated insulation level 3KV/min
• Temperature rise limit of each part of the reactor: core temperature does not exceed 45K, coil temperature does not exceed 55K
• Reactance noise reduction is not greater than 45dB.
• The difference between the reactance values ​​of any two phases of the three-phase reactor is not greater than ±3%.
• Temperature resistance grade H (180C) or above.
• Use environment conditions
• Altitude does not exceed 2000 meters
• Operating environment temperature -25℃C to +45°C, relative humidity does not exceed 909%;
• There is no harmful gas around, no flammable and explosive conductive dust.
• The surrounding environment should have good ventilation conditions. If installed in a cabinet, ventilation equipment should be installed.
