| 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. |
