Abstract
The invention relates to a distribution-box fault indicator used for a low-voltage distribution box. The distribution-box fault indicator includes relay switches, indicative lights and connecting wires, wherein circuit breakers and knife-gate melts in the distribution box are connected with the relay switches respectively. Five indicative lights are controlled by the relay switches, wherein three of the indicative lights are serially connected with relay switches corresponding to the knife-gate melts so that knife-gate-melt fault indication subcircuits are formed. Three knife-gate-melt fault indication subcircuits are serially connected with one indicative light after being connected in parallel and the other indicative light is serially connected with a relay switch corresponding to the circuit breaker. The beneficial effects of the distribution-box fault indicator are that the fault condition in the distribution box is displayed outside the distribution box through a relay indicative-light structure so that troubleshooting procedures are simplified and time for recovering power supplying is reduced.
Description
technical field:
The present invention relates to a kind of panel box fault detector for low-tension distribution box.
technical background:
Low-voltage platform area refers to all low-voltage power supplies region from substation transformer 0.4kV outlet, comprise four kind equipments: comprehensive intelligent panel box, low-voltage cable, voltage circuit and low-voltage tapping box, low-voltage platform area fault is generally also caused by this four kind equipment: comprehensive intelligent panel box fault, low-voltage circuit fault, low-voltage cable fault, low-voltage tapping box fault.Comprehensive intelligent panel box, as first controlling unit in low-voltage power supply region, is also low-voltage platform area fault the first investigation link, if comprehensive intelligent panel box malfunction elimination overlong time can affect whole malfunction elimination flow process, extends power off time.
The common fault of comprehensive intelligent panel box mainly contains following four classes: 1, circuit breaker failure, and generally by user's zero line grounding, earth leakage protection action causes; 2, disconnecting link fault, generally by overload and partially load cause that melt blows and cause; 3, outlet cable fault, generally excessive by customer charge and cable insulation is aging causes; 4, other class faults, comprise that current transformer is abnormal, electric energy meter warning etc.According to actual count, the fault that comprehensive intelligent panel box frequency is maximum is respectively circuit breaker failure and disconnecting link fault, and circuit breaker failure accounts for comprehensive intelligent panel box fault sum 54%, and disconnecting link fault accounts for comprehensive intelligent panel box sum 27%.
Because being all installed on, comprehensive intelligent panel box becomes on platform bar, and 1.6 meters apart from ground, check circuit breaker failure and the disconnecting link fault OOBA (out of box audit) of need to ascending a height, program is loaded down with trivial details, serious slow restoring electricity the time.
summary of the invention:
Panel box fault detector goal of the invention of the present invention: design a kind of panel box fault detector, make maintenance personal detect targetedly maintenance in the failure judgement reason fast of not ascending a height unpacking in the situation that, reduce the required time that restores electricity.
Panel box fault detector of the present invention, comprises relay switch, pilot lamp and wiring; Wherein, in panel box, isolating switch is connected with relay switch respectively with disconnecting link melt, and pilot lamp is controlled by relay switch.
Described relay switch is four, is connected respectively with the isolating switch in panel box with three disconnecting link melts.
Described pilot lamp is five, wherein three pilot lamp are connected with the corresponding relay switch of disconnecting link melt respectively, form disconnecting link melt indicating fault branch road, after three disconnecting link melt indicating fault branch circuit parallel connections, be connected in series a pilot lamp, another pilot lamp is connected with the corresponding relay switch of isolating switch.
The beneficial effect of panel box fault detector of the present invention: with a kind of relay-indicating light structure, panel box internal fault situation is presented at outside panel box, simplifies malfunction elimination flow process, reduce and restore electricity the time.
accompanying drawing explanation:
Accompanying drawing 1 is panel box fault detector structure principle chart of the present invention;
Accompanying drawing 2 is mounting structure figure in panel box fault detector embodiment of the present invention;
Accompanying drawing 3 is pilot lamp arrangenent diagram in panel box fault detector embodiment of the present invention;
In figure, 1 relay switch, 2 pilot lamp, 3 isolating switchs, 4 disconnecting link melts.
embodiment:
Panel box fault detector, comprises 1 relay switch, 2 pilot lamp and wiring; Wherein, in panel box, 3 isolating switchs are connected with 1 relay switch respectively with 4 disconnecting link melts, and 2 pilot lamp are controlled by 1 relay switch.
1 four of relay switches, are connected with three 4 disconnecting link melts with 3 isolating switchs in panel box respectively.
2 five of pilot lamp, wherein three 2 pilot lamp are connected with corresponding 1 relay switch of 4 disconnecting link melt respectively, form disconnecting link melt indicating fault branch road, article three, after disconnecting link melt indicating fault branch circuit parallel connection, be connected in series 2 pilot lamp, another 2 pilot lamp is connected with corresponding 1 relay switch of 3 isolating switchs.
2 pilot lamp are arranged in outside distribution box door.
