what is the meaning and difference between ELECTRICAL
DRAWOUT and MANUAL DRAWOUT?
Answer Posted / ranjana
manual draw out is the De-assembled procedure of
trolleys(VCBs) FROM PANEL.
A circuit breaker racking mechanism has a toroidal spring
connected between an inner and outer racking shaft. The
inner shaft is connected to the cubicle within which the
circuit breaker truck is moved while the outer shaft is
connected to the manual racking mechanism. The spring serves
as a direct mechanical force transmitting connection between
the inner and outer racking shafts when the breaker which
enters the cubicle is moved to the test position. After the
breaker reaches the test position, the inner racking shaft
is latched so that continued racking toward the connected
position charges the spring connection between the two
racking shaft members. The latch may be remotely defeated to
release the spring, thereby to complete the racking of the
breaker to its connected position under the influence of the
charged spring with operating personnel in a remote position.
