Center Break Disconnector (HE)

Designed and developed in compliance with NBR IEC 62.271-102 standard, they ensure the insulation of equipment or segments of substation lines when in the open position, allowing confirming visually that the isolated segment is powered down.

About this Product

What is a switch-disconnector ?

A switch-disconnector is an electromechanical device able to interrupt or establish low-intensity currents at the moment they are driven, and, under normal operating conditions, in the closed position, to withstand high-amplitude currents, such as those of short circuits.

Designed and developed in compliance with NBR IEC 62.271-102,  their function is to ensure the insulation of equipment or parts of substation lines when in the open position, allowing confirming visually that the isolated segment is de-energized.

Opening types 

  • Hook stick switch: Used in distribution substations. Switched by stick;
  • Tandem hook stick switch: Used in distribution substations. Switched by stick;
  • Center break disconnector:  Used in industrial substations due to their simpler construction;
  • Vertical break disconnector: Used mainly in transmission substations due to their excellent endurance to short circuit;
  • Vertical reach disconnector: Used in substation inputs/outputs, connection of upper x lower busbars and bypasses;
     
  • Double side break disconnector: Excellent endurance to short circuit, with smooth operation, since they do not require compensation springs;
  • Horizontal semi-pantograph disconnector: Used mainly in transmission substations due to their excellent endurance to short circuit. Because of its compact size, it can be used in areas with little space;
  • Vertical semi-pantograph disconnector: Used in substation inputs/outputs, connection of upper x lower busbars and bypass.
     

 

Applications

  • Power distribution substations operated by stick switch;
  • Industrial substations;
  • Generation and transmission substations.
