Commutateur automatique à double alimentation HGLD

AC 50/60Hz, 100-3200A
CE certificate



HGLD series dual power changeover switch is an automatic switch which integrates switch and logic control and realizes mechatronics.

It has the functions of voltage detection, communication interface, electrical and mechanical interlocking, and can realize automatic, remote control, mandatory « 0 » and emergency.

Manual operation is widely used in automatic conversion between main power supply system and standby power or automatic conversion and safety isolation of two load equipments in power supply system.

Switches are managed by logic commands issued by control circuit boards.

The motor drives the operating mechanism of the main part of the switch, switching on the breaker circuit or converting the circuit quickly, and realizing safe isolation through obvious visible state.

Description Of Switch Structure

  1. Electric key lock: control switch internal control circuit power supply, when the electric lock is opened, the switch can achieve full automation, operation control and forced « 0 » operation: when the electric lock is closed, the switch can only be operated manually.
  2. Operating handle: When using the operating handle to operate manually, the electric lock must be closed first.
  3. Institutional padlock: special for overhaul, that is, the switch is placed in the « 0 » block position with the operating handle, then the padlock mechanism is connected and the padlock is put on, so that the overhaul can be carried out. (When the padlock is connected, the internal control power of the switch is cut off, and the switch can not be automatically and manually operated.)
  4. Indicators: Indicating the working status of the switch (I, O, II).
