Line, C phases copper conductor distinguish clamping with C phases bus with hexagon socket head cap screw；
Chopper switch is arranged on mounting rail b, and chopper switch bus suitable for reading is with main bus-bar through bolt connection；Lower mouth is through bus
It is connected with stacking bus A phases bus, B phases bus, C phase buses, constitutes distribution system.
Moreover, described plug-in bus tie is four, from top to bottom respectively plug-in bus tie 400A
Two and plug-in bus tie 250A two.
Moreover, described breaker is four, it is engaged with plug-in bus tie, is respectively from top to bottom open circuit
Device 400A two and breaker 250A two.
Moreover, reserving spare space in the lower section of bottom plug-in bus tie.
Advantages and positive effects of the present invention are：
1st, brand-new bus-bar system mounting means.Bus in compact-type low-voltage power distribution cabinet project is to be vertically installed at distribution
The position of the center line of cabinet, stacked arrangement is followed successively by A phase, B phase, C phase from outside to dividing plate is installed.Breaker is then perpendicular to layer
Folded bus, is horizontally arranged at the left and right sides of stacking bus, symmetric arrays.Whole bus-bar system is put in " non-" font.
2nd, the use of plug-in bus tie.Plug-in bus tie one end is connected with breaker inlet wire side terminal,
The other end is plugged on the side of stacking bus, is connected with bus.The plug-in bus tie of standardization instead of conventional busbars,
The bending of branch bar, punching complicated technology program, so as to simplify mounting process, improve installation effectiveness.
3rd, the rapid installation process that bus is not punched.The rapid installation process that bus is not punched, it is safe and efficient, plug simultaneously
The assembling mode of formula, is fastenedly connected through bolt, good contact is effectively ensured, it is ensured that while power supply reliability, carries significantly
High operating efficiency, saves human cost more than 60%.In addition, not destroying copper bar material also, copper bar punching heating is avoided that.
4th, space in cabinet is saved.Traditional low-voltage distribution cabinet is when the timing of cupboard space one, the installation number of internal breaker
It will be very limited.The brand-new relatively conventional low-voltage distribution cabinet of bus mounting means can save small product size more than 30%.
5th, standby installing space.Standby installing space is reserved, reserve load is set up or reduce at any time.Relative to traditional peace
Die-filling formula, change, the increase operation of breaker are more convenient.
6th, product cost is reduced.The bus-bar system of standardization is applied to feeder cabinet, can increase more in the cabinet of identical size
Line loop is had more, cupboard quantity is saved.
7th, modular assembling and mounting means, simplification of flowsheet improve operating efficiency.
8th, the present invention be it is a kind of it is reasonable in design, easy to use, occupy little space, the compact-type low-voltage distribution that manufacturing cost is low
Cabinet, this compact-type low-voltage power distribution cabinet project realizes the standardizing of low-voltage bus bar distribution system, integrated, modular installation side
Formula, revolutionizes the bus punching of conventional low power distribution cabinet, and the pattern that bending is installed can improve installation effectiveness after use.
