When the hot plug system is applied to newly designed hot plug low-voltage switchgear assemblies, the hot plug low-voltage switchgear assemblies comprise the hot plug system, a bottom plate and a bus system, wherein the bus system comprises an insulating bracket and a plurality of bus bars arranged in the insulating bracket at intervals, and the bus bars are distributed in the length direction of the insulating bracket; the bus system and the plurality of hot plug systems are fixedly arranged on the bottom plate, the hot plug systems are positioned at the lateral direction of the bus system, the plug-in end of the adapter faces the bus bar, and the plug-in end of the adapter is inserted into/pulled out of the bus bar through the reciprocating motion of the sliding plate on the base, so that the hot plug systems are inserted into/pulled out of the bus system. The hot plug system of the invention can be directly plugged into/pulled out of (the busbar of) the busbar system of the hot plug low voltage switchgear without cutting off the busbar power supply entering the busbar system. Further, when the hot plug low voltage switchgear is applied to power distribution system power transmission to the functional units, expansion/modification of the functional units can be achieved without cutting off the busbar power supply.

When the hot plug low voltage switchgear is applied to power distribution system to supply power to the functional units, if the functional units connected to the hot plug system are to be overhauled, the hot plug system 3 is usually required to be pulled away from the bus bar system 2 for safety, and accidents caused by the fact that other people insert the hot plug system 3 into the bus bar system 2 by mistake are avoided, and due to the design, the push-pull rod 35 is locked through the locking piece 355, so that other people realize that the hot plug system 3 cannot be inserted into the bus bar system 2 to supply power. Of course, the push-pull rod 35 may also be locked by the locking member 355 after the hot plug system 3 is inserted into the bus bar system 2. Alternatively, the locking piece 322 is mounted to the side of the sliding plate 32 by bolts or rivets; or locking tab 322 is integrally formed with slide plate 32.
Further, in another embodiment, the locking member 355 is a lock. For example, the padlock, the chain lock and the like are convenient to use and good in safety, and at the moment, only a holder side of a key of the lock can take off the lock; of course, the locking member 355 may also be a pin or bolt, or the like.
According to a further optimization of this embodiment, as shown in fig. 1, 3 to 5 and 11, in another embodiment, the wiring device 36 further includes a wiring device 36, where the wiring device 36 includes a wiring box 361 and a conductive strip 362 assembled in the wiring box 361, a flexible conductive strip 362 is formed by connecting a wire inlet end and a wire outlet end of the conductive strip 362 through multiple layers of conductive strips 3621, the wire inlet end of the conductive strip 362 is connected to the wire outlet end of the switching element 33, a connection section between the wire outlet end of the conductive strip 362 and the conductive strips 3621 is fixed in the wiring box 361, and the wiring box 361 is fixed on the base 31. When the hot plug system is applied to the hot plug low-voltage complete switch equipment, and the hot plug low-voltage complete switch equipment is applied to the power distribution system to transmit power to the functional unit, the design ensures that the hot plug low-voltage complete switch equipment is more convenient to use. It is of course also possible to dispense with the design of the wiring device 36, in which case the outlet of the switching element 33 of the hot plug system 3 is connected to the functional unit via a supply bus (typically a rigid conductive branch), and if the hot plug system 3 connected to the functional unit is to be pulled out of the bus system 2, the supply bus is to be pulled out of the outlet of the switching element 33, so that the hot plug system 3 can be pulled out of the bus system 2 smoothly. When the wiring device 36 of the present design is adopted, the conductive sheet 3621 can be bent and straightened due to the design of the flexible conductive bar 362, so that a movement space is reserved for the sliding plate 32, and the feeding bus does not need to be withdrawn from the outlet end of the switch element 33; the invention is more convenient to use. Obviously, the connection device 36 is adapted to the switching element 33; at this time, the outlet end of the wiring device 36 is connected to the functional unit via the feeder bus. Of course, if the feeder bus bar is flexible, the design of the wiring device 36 may or may not be employed.
Based on the further optimization of this embodiment, as shown in fig. 2 to 5 and 8, in another embodiment, the device further includes an interlocking plate 37, the interlocking plate 37 is provided with a through hole 371 and a first window 372, the interlocking plate 37 is placed on the switch element 33, the through hole 371 corresponds to the outlet end of the switch element 33, the opening and closing handle 331 of the switch element 33 passes through the first window 372, and the interlocking plate 37 can reciprocate on the switch element 33 by pulling the opening and closing handle 331; when the opening and closing handle 331 is pulled to enable the switching element 33 to be in an opening and closing state, the through hole 371 is opposite to the wire outlet end of the switching element 33; when the opening/closing handle 331 is pulled to make the switching element 33 in the closing state, the through hole 371 is offset from the wire outlet end of the switching element 33. Obviously, the first window 372 is adapted to the split handle 331 of the switching element 33. The purpose of this design is that the outlet end of the switching element 33 will not be operated when the switching element 33 is in the closed state, making the invention safer and more reliable. When the hot plug system is applied to the hot plug low voltage switchgear, and the hot plug low voltage switchgear is applied to a power distribution system for supplying power to a functional unit, the outlet terminal of the switching element 33 of the hot plug system 3 is connected with the functional unit through a feeding bus, and when the switching element 33 is in a closed state, at this time, the through hole 371 is staggered with the outlet terminal of the switching element 33, so that it is difficult to operate the outlet terminal of the switching element 33, namely, it is difficult to detach the feeding bus from the outlet terminal of the switching element 33; only when the switching element 33 is in the off state, the through hole 371 is opposite to the outlet end of the switching element 33, so that the outlet end of the switching element 33 can be operated smoothly, i.e. the feeding bus bar can be removed from the outlet end of the switching element 33. Similarly, when the feeder bus is connected to the outlet of the switching element 33, the outlet of the switching element 33 needs to be operated when the switching element 33 is in the off state, so that the connection relationship is achieved. When combined with the design of the wiring device 36 (in this case, the wire inlet end of the conductive bar 362 is used to connect with the wire outlet end of the switching element 33, and the wire outlet end of the conductive bar 362 is used to connect with the feeder bus), it is also necessary to connect the wire inlet end of the conductive bar 362 to the wire outlet end of the switching element 33 or remove the wire inlet end of the conductive bar 362 from the wire outlet end of the switching element 33 when the switching element 33 is in the off state.
Further, as shown in fig. 2 to 5 and 8, in another embodiment, the device further includes a limiting plate 38, a second window 381 corresponding to the first window 372 is formed on the limiting plate 38, the limiting plate 38 is fixedly disposed on the switch element 33, and the opening/closing handle 331 of the switch element 33, which is movably disposed between the limiting plate 38 and the switch element 33, passes through the second window 381, of the interlocking plate 37. The interlock plate 37 can be prevented from falling off the switching element 33, making the interlock plate 37 more reliable. Obviously, the length of the second window 381 in the pulling direction of the opening/closing handle 331 is longer than the length of the first window 372, i.e., the second window 381 does not interfere with the movement of the opening/closing handle 331. The fixing connection mode of the above embodiments is preferably a bolt connection mode.
In summary, the plug-and-play hot plug system of the present invention can realize the reciprocating motion of the switching element and the adapter on the base, i.e. the hot plug system of the present invention can reciprocate to realize the plug-and-play. When the hot plug system is applied to a newly designed hot plug low-voltage switchgear assembly, the hot plug system can be directly plugged into/pulled out of (a busbar of) a busbar system of the hot plug low-voltage switchgear assembly under the condition that a busbar power supply entering the busbar system is not cut off.
