Abstract
The utility model relates to an active slotting-tool pinboard feeder box which is composed of an active slotting-tool device, a breaker device, a housing, an operating handle, etc., wherein, the active slotting-tool is arranged on a movable insulating base, and the insulating base and the fixedly arranged low-pressure air breaker are respectively arranged on the top and the bottom surfaces of a bottom plate; the active slotting-tool is connected with the insulating wall penetrating current conducting bolt arranged on the bottom plate by insulating soft wires, and is then led to the low-pressure air breaker; the low-pressure air breaker device and the active slotting-tool device are respectively operated by the respective handle arranged outside the box body. The feeder box can ensure the exact position and arrangement of a bus groove under the condition that the bus groove is charged, and the unexpected accidents can be avoided thoroughly.
Description
The utility model relates to a kind of low voltage bus bar groove active slotting-tool plug-in type feeder box.
At present, both at home and abroad three-phase four-wire system (or five-wire system) low voltage bus bar groove supporting plug-in type feeder box be fixedly slotting tool formula.Being that slotting tool is fixedly installed in outside the feeder box, when the main line busbar of copper (or aluminium matter) in they and the bus duct is pegged graft, is to rely on operating personnel's both hands to hold case, and the pushing casing is wedged slotting tool on the main line busbar.This inserting mode, not only operating physical force is big, and mating force is inhomogeneous, is difficult to capturing position, and main is to be absolutely unsafe.In order to address this problem, although some foreign-made factory has added the insulation backplate on the jack box limit, because no localization machine hook very likely causes live part to shell short circuit accident or generation accident of human electric shock.
In view of the problem of above-mentioned existence, but the purpose of this utility model provides a kind of hot line job, and is easy to operate, operating physical force is little, the active slotting-tool plug-in type feeder box of safe and reliable, scalable slotting tool.
The structure of active slotting-tool plug-in type feeder box described in the utility model is as shown in drawings:
Fig. 1 is a stereoscopic schematic diagram of the present utility model;
Fig. 2 is an internal structure schematic diagram of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Parts such as active slotting-tool device that active slotting-tool plug-in type feeder box is made up of active slotting-tool 24, insulator foot 26, slide block 25, guide rail 23, connecting rod 8, crank 9, rotating shaft 19 and the release unit of being made up of rotating shaft 6, connecting lever 12, fork-shaped bolt 13, connecting rod 4, lv air breaker 2 and shell 1, operating grip 34,35 are formed.Active slotting-tool 24 is installed on the movable insulator foot 26, and insulator foot 26 and hard-wired lv air breaker 2 are installed on the upper and lower surface of base plate 33 respectively.Active slotting-tool 24 is connected with insulation conducting bolt 21 through walls on base plate is installed by insulated flexible cord 22, and is directed to thus on the lv air breaker 2.Lv air breaker device and active slotting-tool device are operated by handle 34,35 in the casing side by rotating shaft 6 and 19 separately.In order to guarantee that active slotting-tool plug-in type feeder box has higher security reliability in manipulating process, on active slotting-tool rotating shaft 19 and breaker rotating axis 6, be respectively arranged with cam 10 and 5.On base plate 33, be provided with interlocking swing arm 31.Interlocking swing arm 31 on cam 10,5 and the base plate constitutes the dual reciprocal interlocking mechanism of active slotting-tools 24 and lv air breaker 2.In the rotating shaft 6 of circuit breaker, be provided with the separating brake fan-shaped hook 11 of interlocking, be provided with case lid cramp 14 at the inner surface of case lid 16.Separating brake is interlocked and can not be opened case lid interlocking device when fan-shaped hook 11 constitutes breaker closing with case lid cramp 14.Simultaneously, in lv air breaker rotating shaft 6, also be provided with separating brake interlocking fanning strip 7, liner plate 15 is provided with pressing plate 20.Can not close after separating brake interlocking fanning strip 7 is opened with separating brake interlocking swing lever arm 17 and pressing plate 20 formation case lids and close lv air breaker interlocking device.
Installation and accurate location for the ease of active slotting-tool plug-in type feeder box in the bottom of cabinet shell 1, are provided with the posting 28 that insulating material is made.
The working method of active slotting-tool plug-in type feeder box is achieved like this:
When circuit breaker 2 is in gate-dividing state, be fixed in the following leg that projection on the cam 5 on the breaker rotating axis 6 leaves the mechanism's swing arm 31 of selling through joint efforts, at this moment swing arm 31 is under the tension of spring 32, rotation counterclockwise, the last leg of swing arm breaks away from the breach on the cam 10 that is fixed in the active slotting-tool rotating shaft 19.So, active slotting-tool rotating shaft 19 is under the effect of operating grip 34, can rotate freely, and the effect by crank 9, connecting rod 8, slide block 25, guide rail 23, make rotatablely moving of handle become the linear reciprocating motion of insulator foot 26, thereby the active slotting-tool 24 that drives on the insulator foot insert or transfer to the main line busbar 27 that matches with it.Before feeder box does not put into operation, active slotting-tool 24 is answered in the retraction casing, it determines the relative position of feeder box and bus duct 30 by means of the location notch on the window frame 29 of posting 28 on the cabinet shell bottom and bus duct 30, and with this feeder box is fixed on the bus duct exactly.
When active slotting-tool 24 was in closure state, the breach of the cam 10 that rotates with active slotting-tool axle 19 was aimed at the last leg of interlocking device's swing arm 31 just.At this moment,, can pass through circuit breaker connecting lever 12, fork-shaped bolt 13, connecting rod 4 drive breaker operator hinges 3 if rotate circuit breaker handle 35, can closed arbitrarily, breaking circuit breaker 2.
When circuit breaker 2 is in the disjunction state, be positioned at the bottom with the separating brake of the circuit breaker axle 6 coaxial rotations fan-shaped hook 11 of interlocking, it and case lid cramp 14 are thrown off.So case lid 16 can freely be opened.
After case lid 16 is opened, case lid pressing plate 20 is no longer pushed down the swing lever arm 17 that is installed on the liner plate 15, so under the tension of spring 18, the rotation of swing lever arm 17 clockwise directions, it fastens the breach of the cam 5 that rotates with breaker rotating axis 6 just.Like this, just make breaker rotating axis 6 not rotate, thereby guaranteed that circuit breaker can't be closed.
Rational in infrastructure, easy and simple to handle, safe and reliable through the active slotting-tool plug-in type feeder box after the above-mentioned design, it can not only be guaranteed that the feeder box bus duct is under the charged situation and locate exactly with bus duct (charged and not charged all can) and install, also has following function simultaneously: promptly have only circuit breaker to be under the disjunction state, could carry out closure or breaking operation to active slotting-tool; When active slotting-tool was not in closure state, circuit breaker then can't be closed; Only after the circuit breaker disjunction, just can open the feed case lid; After case lid is opened, then can't close circuit breaker.Like this, the closure of active slotting-tool and circuit breaker, disjunction program just can meet the requirement of safety operation fully, thereby can thoroughly avoid the generation of unexpected device damage and personal safety accident.
