WINDCAP ® AC CAPACITORS - [GENERAL] |
|
|
|
| |
The compact Windcap capacitor is a self-healing, metalized poly-propylene film capacitor using |
| |
MKK technology with self-healing properties. The current-carrying metal layer (electrode) is |
| |
vapour-deposited onto one side of the film. |
| |
|
| |
|
|
|
|
|
|
|
WINDCAP ® AC CAPACITORS - [ COMPACT DESIGN - LOW HEIGHT, WEIGHT AND VOLUME ] |
|
|
|
| |
Three electrically separated capacitor elements are wound concentrically in a single operatiorl |
| |
onto an insulated metal core tube, which guarantees excellent winding precision. The |
| |
electrodes are connected by metal spraying the face ends of the winding elements. The |
| |
capacitor elements are delta nected (also at 690 and 800 minimize losses. |
|
|
| |
The compact winding elements are housed in a cylindrical aluminum case and hermetically |
| |
sealed by a press-rolled metal lid. |
| |
|
|
|
|
|
|
|
WINDCAP ® AC CAPACITORS - [ TRIPLE SAFETY SYSTEM ] |
|
|
|
| |
Dry technology: instead of a liquid impregnating agent like oil or PCS, the capacitor is filled |
| |
with gas. So there is no risk of fire caused by spurting or leaking oil. Dry design is a must for |
| |
ecologically sensitive applications and insurance follow-up. |
|
|
| |
Self-healing: the capacitor repairs itself after overload. |
|
|
| |
Overpressure disconnector: this prevents the capacitor from bursting at the end of its useful |
| |
life or through electrical or thermal overload. |
| |
|
| |
|
|
|
|
|
|
|
WINDCAP ® AC CAPACITORS - [ INNOVATIVE AND RELIABLE SIGUT ® CONNECTION TECHNOLOGY ] |
|
|
| |
SIGUT terminals ensure reliable and straightforward connection, even in a parallel capacitor |
| |
circuit, with benefits like: |
| |
Simplified parallel connection of capacitors. |
| |
Protection against electric shock hazard (IP20 to VDE 0106 part 100). |
| |
Additional connection of discharge resistors for extra reliability and safety. |
| |
Clamping device to prevent loosening of screws. |
| |
Cable cross-sections up to 16 mm². |
| |
|

|
WINDCAP ® AC CAPACITORS - [ HIGH RUSH CURRENT WITHSTAND CAPABILITY IS CRUCIAL ] |
|
|
|
| |
Capacitors used for power factor correction undergo a lot of switching operations. The high |
| |
inrush currents that go along with this must be handled without degrading useful life. The pulse |
| |
strength of this technology comes in particular from the enlarged, sensitive contact area |
| |
(improved metal spraying). The breakthrough came with a Simens patent called the wavy cut |
| |
plus heavy edge film design. WindCap capacitors can easily handle inrush currents of up to |
| |
300 times rated current. |
| |

|
|
| |
Parallel connection of capacitors. |
| |
Non-detuned capacitors. |
| |
Capacitor banks using standard contactors. |
| |
Restoration after voltage interruptions and brownouts. |

|
WINDCAP ® AC CAPACITORS - [ EXTENDED USEFUL LIFE OF 130,000 OPERATING HOURS ] |
|
|
|
| |
After a long drying phase in a high vacuum to eliminate moisture from the active element the |
| |
capacitor is impregnated. The case is filled with inert gas and sealed. Then routine test are |
| |
performed for gas leakage. |
| |
This production process helps to avoid oxidation and partial discharges (corona effect), |
| |
promoting capacitance stability over an extremely long period, an essential in filter circuit |
| |
applications. |
