The assembled shunt capacitor is mainly used for 110kV, 66kV and 35kV side of main transformer in areas with limited floor space or high seismic requirements, and reactive power compensation for power frequency power system, so as to improve power grid power factor, reduce line loss, give full play to the efficiency of power supply and distribution, and improve the quality of power supply voltage. It has the advantages of good seismic performance, small floor space, easy installation and maintenance, etc.
The main features
1. Adopt the inner unit of the new assembling capacitor, which is safe and reliable in quality.
2. Compact structure, large capacity and small floor space.
3. Multi-insulation platform classification design, the product explosion resistance level is greatly improved.
4. The capacitor body is designed with a terminal box with a signal collector, which is used to collect the voltage, current, temperature, pressure, gas and other signals in the running process of the capacitor to facilitate the monitoring of the running state.
5. The core is made of high-quality new insulation materials and spot-like insulation structure, which can not only ensure good internal insulation performance, but also ensure smooth heat dissipation of the core, making the operation more safe and reliable.
6. The main components adopt bolt and detachable structure, which is not only convenient for installation and transportation, but also convenient for on-site maintenance.
