Cable is entered from bottom of cabinet in cabinet by channel after cabinet, then by loaded on the bus casing inner copper line and breaker on main bus-bar partition board
Enter line side is connected.Although this scheme solves the above problem to a certain extent, wall bushing because of its architectural characteristic,
On the one hand related switchgear depth needs to increase 160mm, keeps entire row cabinet depth inconsistent, to proposing to install after the cabinet of power distribution room scene
Space requirement, and row's cabinet depth disunity, overall effect is bad, on the other hand be located at the indoor vacuum circuit breaker of busbar into
Line copper bar is also required to do section extension copper bar across this bus casing, is then connect with inlet wire armoured power cable, intermediate without absolutely
Other supports such as edge are fixed, and the dynamic thermal stability of connecting copper bar can be affected.Space is walked after this external cause will reserve cabinet
Inlet wire armored cable, therefore the former current transformer for being set to the installation of cabinet rear cross beam is needed to move forward and be installed using fixed beam, structure
Intensity decreases with former scheme than also.
