Abstract
The utility model provides a kind of low-voltage drawer cabinet with plug-in unit of quadrupole, including the crossbeam inside low-voltage drawer cabinet top half, central post is vertical at the lower section at crossbeam center, incoming-line busbar is provided between central post and the cabinet wall of low-voltage drawer cabinet side, replace between central post and the cabinet wall of low-voltage drawer cabinet opposite side provided with a plug-in unit and secondary inserting piece, characterized in that, the width of described central post, which is more than or equal to 15mm, is less than 25mm, a plug-in unit has the phase of A, B, C and N phase four.Further, the width of central post is 15mm.The advantage is that by the pole of plug-in unit three can be changed to quadrupole on the premise of low-voltage drawer cabinet appearance and size and cost is not increased, and cost-effective while meet particular place to the requirement compared with high safety, expand the application scenarios of low-voltage drawer cabinet.
Description
Technical field
The utility model is related to the low-voltage drawer cabinet with plug-in unit of quadrupole, can make power supply industry electrical equipment complete switch
N accompany A, B, C three-phase together by middle breaker carry out disjunction, belong to electric corollary equipment field.
Background technology
It is quality and applied field of the power construction to low-voltage drawer cabinet the need for adapting to China's modernization construction at present
The variation of scape proposes higher requirement.As shown in Figure 1, Figure 2, Figure 4 shows, existing low-voltage drawer cabinet is generally that three-phase disjunction is set
Meter, its central post width is 25mm, on the premise of drawout cubicle size is not changed, can only accommodate the plug-in unit of three pole one time, therefore not
Can realize four it is identical when disjunction, it is impossible to meet specific occasion application demand.To adapt to increasingly fierce market competition, especially
The requirements at the higher level in terms of market is directed to safe handling are tackled, such as in the more place of some human contacts or as hospital is this kind of right
The higher area of safety requirements, often requires that N phases and A, B, C three-phase simultaneously by disjunction together with middle breaker, wherein N connects
Ground, if ground wire connection is insecure or is disconnected, N phases will be powered, and further whole system equipment all can be powered,
Potential safety hazard is just had when carrying out plant maintenance or equipment out of use, such as using the design of above-mentioned three-phase disjunction, easily to hospital
Or resident makes troubles, easily electrical hazard is triggered when serious, economic loss is further resulted in and has influence on the safety of the person.
The content of the invention
The purpose of this utility model is to provide a kind of low-voltage drawer cabinet with plug-in unit of quadrupole.
To realize object above, the utility model provides a kind of low-voltage drawer cabinet with plug-in unit of quadrupole, including sets
Crossbeam inside low-voltage drawer cabinet top half, central post is vertical at the lower section at crossbeam center, central post and low voltage drawer
Incoming-line busbar is provided between the cabinet wall of cabinet side, is replaced between central post and the cabinet wall of low-voltage drawer cabinet opposite side provided with once
Plug-in unit and secondary inserting piece, it is characterised in that the width of described central post is more than or equal to 15mm and is less than 25mm, a plug-in unit tool
There is the phase of A, B, C and N phase four.Further, the width of central post is 15mm.
The utility model has the advantage of can be on the premise of low-voltage drawer cabinet appearance and size and cost is not increased by one
The secondary pole of plug-in unit three is changed to quadrupole, cost-effective while meet particular place to the requirement compared with high safety, expanded low pressure and has taken out
The application scenarios of chest of drawers.

Embodiment
Below in conjunction with drawings and examples, the utility model is described in further detail.
Embodiment
As shown in figure 3, being filled inside a kind of low-voltage drawer cabinet with plug-in unit of quadrupole, low-voltage drawer cabinet top half
There is crossbeam 1, central post 2 is vertically mounted on the lower section at the center of crossbeam 1, filled between central post 2 and the cabinet wall of low-voltage drawer cabinet side
There is incoming-line busbar 3, replace between central post 2 and the cabinet wall of low-voltage drawer cabinet opposite side equipped with a plug-in unit 4 and secondary inserting piece 5.
As shown in figure 5, the width range of central post 2 is to be less than 25mm more than or equal to 15mm, it is preferable that the width of central post 2 is
15mm.Now, 10mm has been installed more than the width between the central post and cabinet wall of a card address, you can will have A, B, C and N
Plug-in unit 4 of four phases is fitted into low-voltage drawer cabinet.
In use, as shown in fig. 6, other electrical equipments in low-voltage drawer cabinet coordinate a plug-in unit 4 to make corresponding modification,
Accessed again by a plug-in unit 4 after the protection control of breaker 6 in drawer after external live electric cable access incoming-line busbar 3
In electrical equipment.Because a plug-in unit 4 is with the phase of A, B, C, N tetra-, wherein N phases are grounded, therefore can together be divided by breaker 6
It is disconnected, N facies tracts point is prevented, has prevented the powered potential safety hazard of system equipment, so as to meet specific occasion, particularly hospital etc.
The requirement that the necessary N phase and phases line in place is segmented simultaneously.
