OWEL - 3-pole indoor disconnector 3,3-36 kV

Application:

Three-pole indoor disconnectors are designed for closing and opening electrical circuits, where no current flows. In the open position, disconnectors creates a visible and safe insulation clearance. Earthing switches mounted on disconnectors, are designed for short-circuiting and earthing networks, previously disconnected from the voltage.

Advantages:

  • simple and modular design allows for reconfiguration
  • the device requires no spare parts
  • possibility of installing the plane motion and rotory motion string drives
  • choice of mounting the drive side (left/right)
  • cooperation with motor drives NS-EL 30-03, NSP 3-04
  • cooperation with manual drives NR1-01, NRWO-4, NR-3
  • simple operation
  • good technical and operational parameters

Compatibility to standards:

  • PN-EN 62271-102:2005/AC:2005
  • PN-EN 62271-1:2009

Operating conditions:

Disconnectors are suitable for working in conditions of interior, at temperatures in range of -5 up to +50°C.

Auxiliary contacts:

Auxiliary contact LP-1 can be installed on both left and right sides of the disconnector. The connector can have up to eight pairs of auxiliary contacts NO/NC.

Construction and operation:

Disconnectors OW-EL type have secant design. The basis of the disconnector is a steel frame. On the basis there are post insulators mounted, on which there is the current path mounted. Interpolar isolation is an air gap, in the version with smaller interpolar divider, the disconnectors are equipped with insulation compartments. Disconnectors OWEL may be driven with motor drives type NS-EL 30-03, NSP 30-04 or manual drives type NR-1, NRWO4 or NR-3. The design of disconnectors switches allows for extension with earthing switches. Earthing switch can be placed lower (from the side of inseparable contact) or it can be placed upper (from the side of separable contact). Disconnector with integrated earthing switch (upper or lower) is equipped with mechanical lock, providing proper switching. On the basis of the disconnector there is earth electrode – type terminal with bolt M12 x 40. Disconnectors can be equipped with an auxiliary contact, coupled with the device at the opposite end of the drive shaft.
