Discharge Reactor ELDr

Discharge Reactor ELDr

Product catalog summary
Overview: The document discusses a discharge reactor designed to meet the increasing demand for shorter discharge periods in capacitor banks. Traditional methods using fixed resistors are insufficient and costly, whereas the discharge reactor offers a more efficient solution by reducing heat losses and avoiding additional heating of capacitor terminals.
Specifications:
  • Construction: Dual reactor with iron core in plastic housing.
  • DC Resistance per Coil: 7600 Ohm.
  • Duty Cycle: Continuous operation.
  • Rated Voltage: 230 to 600V, 3-phase, 50/60Hz.
  • Capacitor Discharge: 5 to 50 kvar.
  • Connection: Direct mounting on capacitor terminal (design L/M).
  • Vibration Stress: Not permitted.
  • Dissipation Losses: Less than 1W.
  • Ambient Temperature: Maximum 40°C.
  • Degree of Protection: IP20.
  • Dimensions: 58 × 49 × 39 mm.
  • Weight: 290 g.
  • Insulation Class: Standard IEC 61558-2-20.
Standards and Compliance:
  • CE Conformity according to 73/23/EWG Low-Voltage Directive and 93/68/EWG Directive for amendment.
Performance Data:
  • Permanent Current (mA): Varies with voltage levels (230V, 400V, 520V, 600V).
  • Reactive Power and Discharge Rates: Varies with voltage levels and kvar ratings, detailing the number of discharges per minute at 40°C and discharge periods in seconds.

Discharge Reactor ELDr-1

DISCHARGE REACTOR ENTLADEDROSSEL EL-Dr The increasing demand for shorter discharge periods cannot be satisfied by traditional discharge means (fixed resistors). The installation of additional fast discharge resistors at the capacitor contactor results in an increa-se in material and installation costs. Our discharge reactor replaces the compulsory fixed resistors and additional rapid discharge resistors, and at the same time it reduces the heat losses inside the capacitor bank. It further avoids additional heating of the capacitor terminals by standard discharge resistors. General technical data Technische Angaben Die wachsende Forderung nach krzeren Entladezeiten kann mit herkbmm-lichen Entladevorrichtungen (Festwiderstande) nicht erfllt werden. Die Installation zusatzlicher Schnellentladewiderstande ist hinsichtlich der Material- wie auch der Installationskosten sehr aufwendig. Unsere Entla-dedrossel ersetzt Festwiderstande und zusatzliche Schnellentladewider鹭stande und verringert gleichzeitig die Warmeverluste der Kompensations-anlage. Darber hinaus wird eine Erwarmung der Kondensatoranschlsse vermieden, wie sie beim Einsatz von Entladewiderstanden auftritt. construction Aufbau dual reactor with iron core in plastic housing Zweifachdrossel mit Eisenkern 7600 Ohm continuous operation Dauerbetrieb 230 ... 600V 3ph, 50/60Hz 5...50kvar direct mounting on capacitor terminal (design L/M) direkt am Kondensator-Anschlufist鹹ck (Ausfhrung L/M) not permitted nicht zulassig < 1W max. 40°C IP20 58 x 49 x 39 mm 290 g B order no.
