Description
Technical field
The utility model relates to one and is applicable to high-tension switch cabinet/arc extinction cabinet--the safe locking device of bus-bar room door-plate and primary element door-plate.
Background technology
High-tension switch cabinet/arc extinction cabinet produced in the market, bus-bar room is door or closing plate structure.Door/shrouding is without any electrical interlocking device, and part producer, pushes down by a room door with electromagnetic lock by panel beating one or twice flanging in bus-bar room shrouding bottom.And when a room is opened wide, electromagnetic lock still can pin, and this just means that bus bar copper row can be charged.
There is drawback is: without latch functions, bus-bar room shrouding without the need to by any instrument, directly to upper extraction, or tilt backwards and can dismantle after extracting, to the bus bar copper row of 10KV and above be caused to close without reliable armouring, outside being exposed to, unexpected personal injury and property loss can be caused.
Meanwhile, if because constructing or overhauling the door/shrouding pulled down, do not load onto in time and bus-bar room also can be caused without closing, there is personal injury and property loss equally.
Utility model content
Technical problem to be solved in the utility model there is provided a kind of structure letter and answers, convenient installation, the safety arc-extinguishing harmonic-eliminating that only lock function is good and suppression cabinet special purpose device.
The utility model main feature is: be made up of electromagnetic lock, interlocking device, locking mechanism, rear upper door-plate, skeleton, electromagnetic lock dead bolt support, rear lower door-plate, hook, impelling sheet, its interlocking device, rear upper door-plate, rear lower door-plate are installed on skeleton, locking mechanism is installed on rear lower door-plate, interlocking device is fixed on locking mechanism upper end, one electromagnetic lock is installed on the left of locking mechanism, one electromagnetic lock dead bolt support is installed between locking mechanism and electromagnetic lock, inside rear upper door-plate, welding one hook, welds an impelling sheet inside rear lower door-plate.
Main feature of the present utility model is: interlocking device is made up of limiting bracket, only locking bar, and it stops locking bar and is welded on limiting bracket lower end.
Main feature of the present utility model is: install a catch in locking mechanism.
The beneficial effects of the utility model are: structure is simple, and convenient application, efficiently avoid potential safety hazard.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model product;
Fig. 2 is the utility model product partial structurtes enlarged drawings;
Fig. 3 is the enlarged drawing of interlocking device in the utility model;
Fig. 4 is the enlarged drawing of locking mechanism in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As accompanying drawing 1, shown in Fig. 2, arc-extinguishing harmonic-eliminating and suppress cabinet Special safety interlock by by electromagnetic lock 1, interlocking device 2, locking mechanism 3, rear upper door-plate 4, skeleton 5, electromagnetic lock dead bolt support 6, rear lower door-plate 7, hook 8, impelling sheet 9 is formed, its interlocking device 2, rear upper door-plate 4, rear lower door-plate 9 is installed on skeleton 5, locking mechanism 3 is installed on rear lower door-plate, interlocking device 2 is fixed on locking mechanism 3 upper end, one electromagnetic lock 1 is installed on the left of locking mechanism 3, one electromagnetic lock dead bolt support 6 is installed between locking mechanism 3 and electromagnetic lock 1, welding one hook 8 inside rear upper door-plate 4, an impelling sheet 9 is welded inside rear lower door-plate 7, as shown in Figure 2: interlocking device 2 is by limiting bracket 10, only locking bar 11 is formed, it stops locking bar 11 and is welded on limiting bracket 10 lower end, as shown in Figure 3: in locking mechanism 3, a catch 12 is installed.
Specific works principle is as follows:
When rear lower door-plate 7 cuts out, impelling sheet 9 promotes only locking bar 11 and is blocked cannot close by the limiting bracket 10 in interlock, must utilize the hook 8 of rear upper door-plate 4 promote limiting bracket 10 with reach close after the effect of lower door-plate 7, be therefore first close rear upper door-plate 4 in closedown to play door-plate 7 afterwards; Rear Xiamen, during 7 closedown, impelling sheet 9 is hooked by the hook 8 of rear upper door-plate 4 after promoting only lock 11 bar rising, and because of when after this Xiamen plate 7 is not opened, after rear upper door-plate 7 does not open to prevent bus-bar room band electric-opening too, upper door-plate is to realize interlock.
Electromagnetic lock 1 is loaded on rear lower door-plate 7, locking device 3 to be loaded on rear lower door-plate 7 and to stretch out dead bolt limit at electromagnetic lock 1, skeleton 5 fills electromagnetic lock dead bolt support 6, can be blocked by the catch 12 in locking device 3 when the rear lower door-plate 7 of rear upper door-plate 4 is at the situation lock electromagnetic lock 1 of not cutting out, with prevent rear lower door-plate 7 do not close when lock electromagnetic lock 1 by force, avoid a room charged when rear lower door-plate 7 does not cut out.When rear lower door-plate 7 cuts out, electromagnetic lock dead bolt support 6 promotes catch 12 and pins electromagnetic lock 1 to reach electromagnetic lock 1 when rear lower door-plate 7 cuts out.After rear lower door-plate 7 locking of electromagnetic lock 1, rear upper door-plate 4 cannot be opened, and could must first open rear lower door-plate 7 successively, then open rear upper door-plate 4, and during non-power-off, rear upper and lower door-plate cannot be opened after bus-bar room power-off.When needing energising to run, first must close rear upper door-plate 4, otherwise rear lower door-plate 7 cannot locking, rear lower door-plate 7 must could pin electromagnetic lock 1 when cutting out.
