Abstract
The utility model relates to a potential display self-checking unit which mainly comprises a switch cabinet panel, wherein the switch cabinet panel is provided with a group of detecting ports, a potential display, a transfer switch and an indicator light; a self-checking unit plug-in board is provided with detecting plugs matching with the detecting ports, and the detecting plugs are externally provided with a group of self-checking test loops. The utility model has the advantages that: after the self-checking test loops of the potential display are added, not only the operation order can be made according to the conventional process, but also the potential display is immediately detected to be good before an earth switch is shut off, the operation of detecting whether the potential display is good or not is safer and more reliable compared with the operation before the switch is shut off, the running and ordering time is reduced, and a lot of power failure operation time is saved compared with the direct electricity test, thereby being favorable to improving the social image of electricity enterprises, saving the working time, and improving the economic benefit.
Description
Technical field
The utility model relates to a kind of display self-checking unit, especially a kind of electrification display self-checking unit.
Background technology
Newly " safety " 4.3.1 bar offers some clarification on that at first will to prove conclusively electroscope before the electrical verification intact, can't have test on the electric equipment can to adopt high pressure generator to prove conclusively electroscope good.
At present, closed handcart cabinet has obtained using widely in electric system, but it is more time-consuming in the actual field operation circuit to be carried out this step operation of electrical verification, because conventional electrical verification all is direct electrical verification, and the mentality of designing of closed handcart is indirect electrical verification, we must pull out wheelbarrow switch outside the cabinet in daily operation of relocating the road maintenance, and utilize the electrical verification handcart that baffle door is opened, on line contacts, carry out electrical verification, promptly time-consuming, dangerous again, and wheelbarrow switch pull out cabinet do not meet outward yet dispatch state because conventional line inspection switch handcart need not pull out outside the cabinet, and utilize the application of the charged display instrument of capacitance type sensor principle making to reach its maturity at present, in [2003] No. 58 files of peaceful electricity peace also clearly with the foundation of charged display instrument as electrical verification, but must the conclusive evidence electrification display before the operation intact errorless, and online route stand-by heat directly changes the line maintenance operation into the time can't to check electrification display intact, so real enforcement also has certain difficulty.The principle of work of charged display instrument is all identical, but since the capacitance probe that different manufacturers adopts because model or specification difference, its output voltage may be different, bring some inconvenience for the unitarity of transforming, unified to change the probe workload bigger and have a power failure.
The utility model content
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of electrification display self-checking unit is provided.
The utility model solves the technical scheme that its technical matters adopts: this electrification display self-checking unit, mainly comprise switch cabinet panel, described switch cabinet panel is provided with one group and detects mouth, electrification display, switch and pilot lamp, the self-checking unit plug-in unit is provided with and detects the test plug that mouth matches, the external cover self-checking loop of this test plug.
Described self-checking unit plug-in unit is provided with the detection pilot lamp, and described detection mouth and test plug have four.
The effect that the utility model is useful is: the line maintenance operation that the 10kV enclosures is general, wherein 3/4ths time is that flower is on electrical verification, comprise and move switch cubicle to the cabinet outer platform, after the electrical verification handcart pushed operations such as switch cubicle, and must check that charged display instrument is normal before the electrical verification operation indirectly, the charged display instrument three-phase of audit by comparison lamp extinguishes before closing the ground cutter, this operation must insert operation order, so run up and down with the also expense relatively of time of making out an invoice, if it is undesired to check, this operation order also must be drafted again so, and adds after the self check loop of charged display instrument, and not only operation order can be drafted in a conventional manner, and closing ground, to detect charged display instrument immediately before the cutter intact, come safe and reliablely than checking before the drag switch that charged display instrument is intact, run and make out an invoice the time in the middle of having reduced, compare direct electrical verification, saved a large amount of power failure running times especially, help promoting the social image of electric power enterprise, saved the working time simultaneously, improved economic benefit.
Description of drawings
Fig. 1 is a main TV structure synoptic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model self-checking unit plug-in unit part;
Reference numeral: switch cabinet panel 1, detect mouth 2, electrification display 3, switch 4, pilot lamp 5, self-checking unit plug-in unit 6 detects pilot lamp 7, test plug 8.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, this electrification display self-checking unit mainly comprises switch cabinet panel 1, and described switch cabinet panel 1 is provided with one group and detects mouth 2, electrification display 3, switch 4 and pilot lamp 5, and described detection mouth 2 and test plug 8 have four; Self-checking unit plug-in unit 6 is provided with and detects mouthful 2 test plug that match 8, these test plug 8 external cover self-checking loops, and described self-checking unit plug-in unit 6 is provided with and detects pilot lamp 7.
Respectively draw a line at the electrification display three-phase input end, it is fixing as test usefulness that the end of a thread adds dedicated terminals, during power failure, as long as on calibrating terminal, add operating voltage with voltage generator, charged display instrument pilot lamp shows can judge that normally charged display instrument is normal, and the inductive probe three-phase independently is provided with, and the bad simultaneously possibility of three probes is almost nil.
Test lead should be fixed on switch cubicle charged display instrument below or top, should add a cover at ordinary times, and voltage generator can be by special-purpose manufacturer production, and the work area is by the electric parameter that provides various device relevant is provided.By charged display instrument external is overlapped self check or test loop, working properly by the charged display instrument of detection conclusive evidence before operation is more rational.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
