PHASECAP ® HD AC CAPACITORS - [HIGH INRUSH CURRENT WITHSTAD 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 metalspraying). The breakthrough came with a Siemens patent called the wavy cut, |
| |
plus heavy edge film design. PhaseCap HO capacitors can easily handle inrush currents of up |
| |
to 200 times rated current. |
| |
|
| |
|
|
|
|
|
|
|
PHASECAP ® HD AC CAPACITORS - [ AND WHERE IT IS CRUCIAL] |
|
|
|
| |
Parallel connection of capacitors. |
| |
Non-detuned capacitors. |
| |
Capacitor banks using standard contactors. |
| |
Restoration after voltage interruptions and brownouts. |

PHASECAP ® HD AC CAPACITORS - [ EXTENDED USEFUL LIFE 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. |
| |
The Compact Phasecap HD capacitor is a self healing. metalized polypropylene film capacitor. |
| |
The current-carrying metal layer (electrode) is vapour-deposited onto one side of film. |
| |
|
|
|
|
|
|
|
PHASECAP ® HD AC CAPACITORS - [ COMPACT DESIGN - LOW HEIGHT, WEIGHT AND VOLUME] |
|
|
| |
The entire capacitor is composed of three single-phase element stacks. The electrodes are |
| |
connected by metal spraying the face ends of the winding elements. The capacitor elements |
| |
are delta connected. The winding elements are housed in a cylindrical aluminum case and |
| |
hermetically sealed by a press-rolled metal lid. |
| |
|
| |
|
|
|
|
|
|
|
PHASECAP ® HD AC CAPACITORS - [ TRIPLE SAFETY SYSTEM ] |
|
|
|
| |
Dry technology: - instead of a liquid impregnating agent, 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. |
| |
|
| |
|
|
|
|
|
|
|
PHASECAP ® HD AC CAPACITORS - [ INNOVATIVE RELIABLE SIGUP-CONNECTION TECHNOLOGY ] |
|
|
|
| |
SIGUT terminals ensure reliable and straightforward connection, even in a parallel capacitor |
| |
circuit, with benefits like |
| |
Simplified parallel connection of input ends in series. |
| |
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 35 mm². |
