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 upto 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 mm˛.
