1. Bus system 1
The bus adapter used in bus system 1 is more miscellaneous, and -Q1 selects a bus type blocking switch that can be directly attached to the bus; -Q11 is a 3VL2 switch, select an appropriate universal adapter to hook up to the bus; The 3-pole switch-Q12 ——- Q15 are less than 63A, but the 3RV bus cannot be used, and the single-branch rail bus adapter is selected to be hooked to the bus; -F11——-F26 is a single-pole switch, -Q30.1——- Q30.6 is a leakage protection switch at the north and south poles, with a capacity of less than 63A, and the bus adapter cannot be used to connect to the bus, considering the two-phase balance, after using the unipolar or North and South pole busbars respectively, they are connected to the four 01563 connection modules connected to the bus system.
2. Bus system 2
In the bus system 2, this group is relatively clear, the capacity of the -Q40.1 ——- Q40.6 power supply to the maintenance power box is 100A, and with leakage protection, the original planning model is the 4-pole circuit breaker of the Siemens 3VL1 series, and the corresponding specifications of the 4-pole RCD leakage protection module are installed at the outlet end of the 3VL1 switch. In the previous project, there was a 3VL1 series of 4-pole circuit breaker with a 4-pole RCD leakage protection module, and the confluence mode at that time was to add an additional N row on the basis of Figure 3, and each switch was connected with 4 wires of 35mm², which took up more space.
After checking the Wiener sample, Wiener does not have a universal adapter suitable for the 4-pole circuit breaker of 3VL1, but there is a universal adapter suitable for the 4-pole circuit breaker of the 3VL2 series, so the -Q40.1——-Q40.6 circuit breaker was upgraded to a shell level, insisting that the rated current of the circuit breaker remains unchanged, using the 4-pole circuit breaker of 3VL2 and the corresponding 4-pole RCD leakage protection module, and using the Wiener universal adapter 32578 for the 4-pole switch of Siemens 3VL2. Two more 01485 4-pole bus frames were added to the bus bar to increase the strength of the bus system. The RCD module is directly connected to the outlet cable of the 3VL2 through the copper bar at the upper end, and the external cable is directly connected to the lower end of the RCD module.
Whether it is drawing a schematic diagram or wiring, there will always be such a misunderstanding, thinking that the N pole of the 3VL four-pole switch is on the far right of the switch, but in fact, the N pole of the 3VL switch is on the left, and Wiener's 4-pole universal bus product fully takes into account this characteristic of the 4-pole switch. This is the first time to use the 4-pole bus system in the power distribution cabinet of the ship unloader project, after the use, in addition to the control line of the auxiliary contact, the 35mm² line of the main circuit of the 6 switches do not have to be connected, saving the device space and saving the line. It can be seen that in the above figure, as long as one end of the copper bar as a connection to the external incoming wire is punched, the rest of the copper bar is not punched, which saves man-hours and improves production efficiency.
Bus system 1 and bus system 2 come from the same power supply, because the space in the cabinet is limited, artificially divided into 2 groups, 2 groups of bus bars are selected at the inlet of each bus system 3-pole terminal board 01538 and 4-pole terminal board 01162, after 25×10 copper bars are connected, 2 sets of bus boards are connected under the blessing of not cutting off the busbar. When planning, the length of the two groups of bus systems is common, and the bus system 1 has an exposed part of the bus, and the 01245 bus cover is used for protection as a backup.
3. Bus system 3
Bus system 3, mainly for the lighting power supply, -F41.1——-F49.1 is a 3-pole SSJ switch, the capacity is 32A, the lower end is connected to the SSM leakage protector-F41.2——-F49.2, and the Wiener double-support rail bus adapter is selected. In the conventional selection of a length of 200mm double-supported rail bus adapter, it is found that after the length of the double-supported rail bus adapter subtracts the height of the 2 equipment, the gap between the 2 equipment is only about 20mm, and the upper and lower equipment can not be connected at all, in view of this situation, the ship unloader assists the distribution cabinet to specially select the double-support rail bus adapter with a length of 260mm, so that there is enough space between the SSJ switch and the SSM leakage protector. Driver's cab lighting-F60 uses a single-support rail bus adapter to hook up to the bus system, -F61——-F71 is a 2-pole leakage protection switch, and the bus adapter cannot be used, considering the two-phase balance and using the North and South Pole SSJ busbar busbar, it is connected to the three 01563 connected to the bus system. The maximum incoming capacity is 160A, the 01240 wiring board is selected as the incoming line of the bus system, which can be connected to 6-50mm² wire, and the whole cabinet is connected to the bottom terminal at the inlet of this group of busbars, if this group of busbars is placed in the direction near the bottom of the cabinet, there is no need to wire, and the external wires can be directly connected to the 01240 wiring board.
To sum up, after the ship unloader assists the distribution cabinet with the bus system, the circuit breaker is connected to the bus through the bus adapter, the universal adapter, etc., and the incoming wire of the corresponding circuit breaker does not have to be wired, which reduces the wiring, saves the device space in the cabinet, and reduces the wiring fault together. When the bus bar is only used as the copper bar of the incoming line, it needs to be punched to connect the external wire, and when it is used as the support and busbar of the bus system, only the rectangular bus bar is used, and there is no need to punch holes, and there is no need to bend, which saves a lot of man-hours and is not easy to make mistakes. The ship unloader assists the power distribution cabinet basically without taking a large line, and the rest is connected to the control line, the trunking will not be full, and the protection is convenient, and then the ship unloader system is safe and stable operation.
