CKSC Dry type iron core series reactor

Main purpose and scope of application
CKSC dry-type iron core series reactor is an important supporting equipment for the reactive power compensation device of the power system. After the power capacitor is connected in series with the dry-type iron core reactor, it can effectively suppress the high-order harmonics in the power grid, limit the closing inrush current and operating overvoltage, improve the voltage waveform of the system, and increase the power factor of the power grid. The safe operation of the equipment has played a major role.

Model and meaning

Working conditions
1. The altitude of the installation site: ≤2000m;
2. Ambient temperature: -25℃~+45℃, relative humidity ≤90%;
3. No harmful gases around, no flammable and explosive materials;
4. Surrounding environment There should be good ventilation conditions.

Main technical parameters
1. Rated voltage 6kV, 10kV, 35kV;
2. Rated frequency 50Hz;
3. The temperature resistance level reaches H level (180℃). During normal operation, the iron core temperature rise of the dry-type iron core reactor is not more than 85K , The temperature rise of the coil is not more than 95K;
4. The dry-type iron core reactor can run for a long time at 1.35 times the rated current;
5. The noise of the dry-type iron core reactor is not greater than the national standard.

 Structural features
1. The iron core of the CKSC dry-type iron core series reactor is made of high-quality imported silicon steel sheet, the core column is divided into even small sections by multiple air gaps, and the air gap is insulated by epoxy cloth board to ensure that the air gap is in the reactor There will be no change under long-term operation;
2. The end face of the iron core adopts high-quality silicon steel sheet end face glue, which makes the silicon steel sheet firmly bonded together, which greatly reduces the noise during operation and has better anti-corrosion performance;
3. The coil is Epoxy casting type, epoxy glass mesh cloth is laid on the inside and outside of the coil for reinforcement. The H-grade epoxy casting system is used for casting under vacuum. The coil has not only good insulation performance, but also high mechanical strength, which can withstand large current impacts and Hot and cold shock without cracking;
4. Epoxy cast coils do not absorb water and have low partial discharge, and can operate safely under harsh environmental conditions;
5. The upper and lower ends of the coil use epoxy pads and silicone rubber shock-proof pads to effectively reduce The vibration during the operation of the coil is reduced.
