Abstract
The utility model relates to a power distribution box fault indicator used for a low-voltage power distribution box. The indicator comprises relay switches, five indicator lights and wires. A breaker and three knife switch melt bodies in a power distribution box are connected to the four relay switches respectively. The indicator lights are controlled by the relay switches. Three of the indicator lights are respectively in series with the relay switches corresponding to the knife switch melt bodies to form knife switch melt body fault indicating branches. The three knife switch melt body fault indicating branches are parallelly connected and then connected to one of the indicator lights in series. Another one of the indicator lights is in series with one of the relay switches corresponding to the breaker. The beneficial effects are that internal fault situations of the power distribution box is shown outside the power distribution box through a relay-indicator-light structure, so that the troubleshooting process is simplified, and time for restoring power supply is reduced.
Description
technical field:
The utility model 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 that low-voltage platform area fault first is investigated 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:
The utility model panel box fault detector goal of the invention: design a kind of panel box fault detector, make maintenance personal in the failure judgement reason fast of not ascending a height unpacking in the situation that, detect targetedly maintenance, reduce the required time that restores electricity.
The utility model panel box fault detector, 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 by relay switch control.
Described relay switch is four, is connected respectively with isolating switch and three disconnecting link melts in panel box.
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 the utility model panel box fault detector: 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.
brief description of the drawings:
Accompanying drawing 1 is the utility model panel box fault detector structure principle chart;
Accompanying drawing 2 is mounting structure figure in the utility model panel box fault detector embodiment;
Accompanying drawing 3 is pilot lamp arrangenent diagram in the utility model panel box fault detector embodiment;
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 by 1 relay switch control.
1 four of relay switches, are connected with 3 isolating switchs and three 4 disconnecting link melts 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.
