9.1kv 337 kVar Single Phase High Voltage Filter Power Capacitor

1. Overview of 9.1kv 337 kVar Single Phase High Voltage Filter Power Capacitor

      Medium voltage shunt capacitor/High voltage shunt capacitor is composed of a pack, a case, outlet porcelain busing, etc. The two sides of stainless steel case are welded with hanging brackets for installation, and one hanging bracket is equipped with a grounding bolt. In order to adapt to various voltages, the pack is composed of several small elements connected in parallel and series. The capacitor is equipped with a discharge resistor.

2. Purpose of 9.1kv 337 Kvar Single Phase High Voltage Filter Power Capacitor

       Medium voltage shunt capacitor/High voltage shunt capacitor are suitable for 50Hz or 60Hz AC power systems to improve the power factor of the power system, reduce line losses, improve the quality of the power supply voltage, and increase the active output of the transformer.

3. Main features of 9.1kv 337 Kvar Single Phase High Voltage Filter Power Capacitor

• 3.1 Casing: Cold-pressed, anti-fouling type casing is adopted, and the creepage distance is not less than 31mm/kV.
• 3.2 Mature internal fuse technology.
• 3.2.1 After testing, the internal fuse can isolate the faulty component within 0.2ms, the release energy of the fault point is not more than 0.3kJ, and the remaining intact components are not affected.
• 3.2.2 Advanced concealed internal fuse structure, using oil gap arc extinguishing, reducing the possibility of blasting the capacitor case.
• 3.2.3 The internal fuse protection and relay protection have perfect coordination standards to ensure the safe and reliable operation of the entire device.
• 3.3The main insulation adopts a composite insulation structure, which not only guarantees excellent electrical performance, but also has a certain degree of mechanical strength, which ensures that the insulation of the capacitor complete set of devices is 100% reliable without protection.

 4. Installation of 9.1kv 337 Kvar Single Phase High Voltage Filter Power Capacitor

• The horizontal separated plate shall not be mounted, or it may block air flow. Outlet for cooling air shall be mounted on the top of each group of capacitors.
• Before capacitors mounted on support, it shall allocate the capacitance, make phase capacitance to be balanced.
• Wire connection for capacitors shall use soft conductor. The side of capacitor with nameplate shall face outside, convenient for inspection.
•  When rated voltage of capacitor is equal to the system voltage, the capacitor can be directly mounted on steel support, and the shell of capacitor is earthed and well connected. If the rated voltage of single phase capacitor less than system voltage, please utilize star connection for these capacitors, at this case the shells of series connected capacitors shall absolutely isolated from earth, its insulation level not less than rated voltage of the system.
