Medium voltage motor control center instrument compartment

A cabinet for enclosing a controller, said controller being subject to arcing, which produces arc gasses, said cabinet comprising:

• an enclosure including a plurality of walls enclosing said controller and a barrier panel defining an instrument compartment and a high-voltage compartment in said enclosure, wherein said barrier panel provides a barrier to built up gasses generated during an arc fault in said high-voltage compartment;
• a door for accessing said instrument compartment;
• a mounting panel for supporting a plurality of instruments;
• a door hinge connecting said door to said mounting panel;
• a telescoping assembly for moving said door and said mounting panel in spaced relation to said enclosure;
• a panel hinge connecting said mounting panel to said telescoping assembly wherein said mounting panel swings away from said telescoping assembly and permits access to said barrier panel;
• and
• a removable panel for providing access to said high-voltage compartment, said removable panel cooperating with an opening in said barrier panel;
• wherein said removable panel contains the built up gasses generated during said arc fault.

A cabinet for enclosing a controller, said controller being subject to arcing, which produces arc gasses, said cabinet comprising:

• a plurality of walls defining an enclosure,
• an instrument rack defined by a door and a mounting panel, said door hingedly connected to said mounting panel,
• a telescoping member hingedly connected to said mounting panel at a first end, said telescoping member fixedly connected to said enclosure at a second end, said telescoping member adapted to allow said instrument rack to be extracted from said enclosure,
• an isolation assembly including a barrier panel dividing said enclosure into a first compartment containing said instrument rack and into a second compartment containing high-voltage electrical equipment.

A cabinet for enclosing a controller, said controller being subject to arcing, said cabinet comprising:

• a means for enclosing said controller;
• a means for isolating an instrument compartment from a high-voltage compartment;
• a means for supporting a plurality of instruments on a vertical panel in said instrument compartment;
• a means for extracting said means for supporting from said instrument compartment;
• and
• a means for accessing said high-voltage compartment through said instrument compartment.
