One purpose> When capacitors compensate for capacitive reactive power, they are often affected by harmonic current closing inrush and operating process voltage
causing capacitor damage and power factor reduction. For this reason, it is necessary to A series reactor is installed at the front end of the capacitor to suppress and absorb
harmonics to protect the capacitor, avoid the influence of harmonic voltage and current and impact voltage and current, improve power quality, increase system power factor
and extend the service life of the capacitor.
Two structural features
The reactor is divided into three-phase and single-phase, both of which are dry cores
The core is made of high-quality cold-rolled silicon steel sheets, punched and sheared by a high-speed punch, with small burr rules The uniform lamination is neat and beautiful, ensuring the performance of the reactor at low temperature and low noise
The coil is made of high-quality insulated wire and wound by a special machine, which has the advantages of good flatness and beautiful appearance
During the assembly process of the reactor, all clamps have undergone anti-corrosion treatment. The key clamps are made of non-magnetic materials and have been pre-baked in vacuum
The process of dipping paint and heat baking and curing makes the reactor coil and iron core firm. Integrated into one, greatly reducing the temperature rise and noise during operation
Effectively improving the quality factor of the reactor and reducing harmonics
The overall dimensions of the reactor are designed with reference to the standard cabinet size, and the small size is convenient for wiring. Greatly save users’ cabinet cost investment.
Three environmental conditions for use
The lifting height does not exceed meters
The ambient temperature ranges from ℃ to ℃, and the relative humidity does not exceed
No harmful gases, no flammable and explosive items
The surrounding environment should have good ventilation conditions. If it is installed in a cabinet, ventilation equipment should be installed.
