Power capacitor for electric induction heating system

RFM-S type

Mainly used in nominal voltage less than 4KV,frequency below 200KZ,controllable or adjustable ac voltage system,specially used to improve induction heating, melting, mixing or casting device,and similar applications power factor or loop characteristic,indoor capacitor unit and capacitor set.
1)Main technical data:
1.Solid dielectric:All film,polypropylene film

   Liquid dielectrics:PXE,None PCB

2.Capacitance Tolerance:-5%~+10%

3.Rated current frequency:50Hz or 60Hz

4.Continuous over current capability:1.15In under rated VAC

5.Over voltage capacity:Under 1.05Un≤12hours in every 24hours

7.Between two terminals:10 seconds under 2.0Un(VAC)or 4.0Un(DC)

8.Between case and terminal:10 seconds Under 2.15Un,lowest voltage=2000V

9.Dielectric loss:tgδ≤0.0008

10.Discharge resistor inside(if need to have):decrease to ≤50V in 5minutes after cut capacitor from

system

11.Insulation resistance,water cooling pipe inside case and insulator on terminals

12.Environmental condition operation:sea level elevation≤1000m,ambient operation temperature:-

40~+50°C,residual voltage≤10% Un when power on,entrance water pressure≤0.3MPa,entrance water temperature≤30°C,cooling water's flow≥6L/min,soft water of no impurities,PH:6~9

2)Structure:Be mainly composed of two parts:the shell and the core.

1.The shell is a rectangular case of sealing structure bently welded by aluminum plate,silicone rubber sealed,porcelain bushing supported wiring guide-bar and cooling pipe interface;welding holders on the two side of the case for Handling and installation.

2.The core is made up of components,insulators and cooling water pipes,the cooling water pipes and the components plate directly welded into a whole,used as a part of electrode as well as thermal carrier,playing cooling effects.

3.The components use polypropylene film as media,the soft aluminum foil is a kind foil components with plate winding and squashing,for high voltage components,in order to  improve electric centralized phenomenon,adopting aluminum foil edge folding measures.

3) Various dimensions and specifications,made according to cutomers' requirements.

4)High quality and safety,professional.

5)Aluminum shell,be useful to release heat.

6)Comforts to GB/T3984 and IEC60110,have passed ISO9001:2000 international product quality

system,CE,CQC,UL certification.
