Application and Sort
1.Application: This series electric switch cabinet, are suitable for the tower
crane which mainly usded in skyscraper , reservoir dam , power plant ,etc. Can
control cranes in starting , timing, braking and reversing the motors.
2.Condition of work:
(1)The height above sea level does not exceed 2000 meters ; (2)The temperature of
medium around is not higher than +40 degrees Centigrade , is not lower than - 30
degrees Centigrade;
(3)The relative humidity does not exceed 85% ;
(4)The medium around has not exploded dangerously, there is no conductive powder
and can destroy such places as the insulating corrosivity gas ,etc. ;
(5)Protect the grade and adopt IP54 , IP55.
3.Code name of one kind of groups: QT- tower crane Pattern, characteristic code name:
Z - is it is it rise tower machine , X - lay person who turns tower round ,
S - is it is it rise tower machine , K - install the tower machine , G - the regular
type tower fast by oneself to turn round to lay by oneself to turn round to
go to Classify: Switch board (case ) this according to related tower machine blow
gravity square with can divide for 16t.m , 20t.m , 25t.m , 30t.m , 40t.m , 50t.m
, 60t.m, 63t.m , 80t.m, 100t.m, 125t.m, 160t.m, when more than ten kinds of
specifications.
4.framework
This electric switch board adopted standard of GB9462-88 " technological condition
of the tower crane ", the shell should be made curved with the stencil plate
, according to the needs of users' reality, can make into different external
dimension and size of installation . Install way adopt hanging type or base type
, inside electric component its can select different products of type for use,
for instance the contactor can select series of Model CJ20 , LC1 series , B series
,etc. for use , can also select for use and import the component .
5.elements
This serial electric switch boards cooperate with hoist control cabinet, one
that is to tower crane is it rise , turn round to get up, car become piece , starting
, reversing is it control to transfer the speed , apply the braking that cart
walk, realize distribution of supporting , short out , pass electric current
, overvoltage , owe voltage , zero , disconnected phase , equal to protecting to
hoist by mistake. Serial electric switch board this adopt vortex brake and switch
over electrical machinery rotor way that resistance combine together go on speed
of transfering, is it transfer speed or coupling is it step down starting is
it switch over resistance transfer speed , electromagnetic to transfer to difference
transfer speed , moment electrical machinery transfer the speed to add to
vary voltage very much to become, can adopt frequency conversion to adjust speed
and PLC control method . Each sport organization in the tower machine can adopt different adjusting the speed way .
