   IV.Nouns explanation
      1.The state of removable parts in the switch gear
      (1) Location state: a state of removable parts in the switch cabinet, at which the circuit breaker installed
on the removable parts can be operated by switch on and off; the crank of propulsion mechanism can not be rotated,
and removable parts can not be moved. The location state of removable parts can only be realized at working
position and test (storage) position. On and off of location gate realized through the interlock between
propulsion mechanism and circuit breaker mechanism.
   (2) Shift state: a temporary state of removable parts in the switch cabinet, at which the circuit breaker
installed on the removable parts can not be operated, the crank of propulsion mechanism can be rotated, the
removable parts can be moved between test position and working position. On and off of shift state can be realized
through interlock between propulsion mechanism and circuit breaker mechanism.
        2. The position of removable parts in the switch cabinet
        (1) Working position: a location state of removable parts in the switch cabinet, at which the loop of switch
cabinet connected, and same with the auxiliary loop.
    (2) Test position: a location state of removable parts in the switch cabinet, at which the auxiliary loop is
connected, the main circuit loop is cut off, and the static and dynamic contact is partitioned by the metal
curtain plate.
    (3) Cut off position: if removable parts at test position in the cabinet, then cut off the auxiliary loop,
the removable parts will be at off position.
