Reclosers-Three-Phase Electronically Controlled Type VSO
The VSO recloser features three vacuum interrupters, oil insulation, and an operating mechanism in an integral mounting frame. The electronic control is housed in a separate cabinet. Constructed of welded angle- and channel steel, the VSO recloser frame facilitates recloser handling, simplifies mounting procedures, and adds rigidity to the mounting structure. It provides a convenient mounting location for the tank-lifting windlass, which allows easy access to the interior of the recloser whether it is mounted on the pole or in the substation.

A complete VSO recloser assembly consists of:
- The recloser unit which includes an integral mounting frame, three vacuum interrupter assemblies, and an operating mechanism.
- The electronic control housed in a separate cabinet.
- An interconnecting cable.
Current interruption takes place in the three vacuum interrupter assemblies. A moving contact in each interrupter assembly is driven by the operating mechanism of the recloser.
The 24-volt closing and opening signals from the electronic control are powered by the control battery. A charging system in the control maintains the required battery charge.
