Electric wiring electric leakage simultaneously charges cabinet, and distribution box becomes as dangerous source, is easy to produce accident and threatens personal safety.Cause
This, existing distribution box, which exists, lacks ground connection instruction and charge indicating device, has the problem of certain security risk.
Utility model content
The purpose of the utility model is to provide a kind of distribution box real-time earthing safety indicating devices.The utility model tool
There are ground connection instruction and charge indicating device, thus the security risk of the utility model is small, it is not easy to electric shock accidents occurs.
The technical solution of the utility model includes: a kind of distribution box real-time earthing safety indicating device, the case including line with ground
Body, cabinet is equipped with indicator light, indicator light and ground line and the intracorporal working power of case is formed into a loop；Cabinet front is additionally provided with
Potential indicator, potential indicator include transparent shell, are equipped with several horizontal main shafts in transparent shell；The every master
The periphery of shaft is connected with nonmetallic warning panel, and the tie point of the two is in side of the main shaft axis far from cabinet；
Part of the warning panel more than main shaft is equipped with metal foil, and warning plate surface is equipped with reflecting coating.Above-mentioned instruction lamp string
It is associated with resistance.
In a kind of distribution box real-time earthing safety indicating device above-mentioned, horizontal time is additionally provided with above every main shaft
Shaft, and secondary shaft is in side of the main shaft far from cabinet, the lower part of secondary shaft is connected with sheet metal.
In a kind of distribution box real-time earthing safety indicating device above-mentioned, the lower section of the main shaft be equipped with under warning panel
The stopper of portion's cooperation, stopper are arranged on transparent shell.
In a kind of distribution box real-time earthing safety indicating device above-mentioned, the indicator light is light emitting diode.
Compared with prior art, the utility model takes electricity as working power from distribution box, selects indicator light and a resistance
Series connection is formed into a loop using ground line.After ground path is complete as a result, indicator light shines, and does not otherwise shine, and operator can be with
It is intuitively known ground path situation.Meanwhile tank surface is provided with the warning panel of overturning.It is alert in the uncharged situation of cabinet
Show that plate is self-possessed, the warning with reflecting coating is face-down.Once cabinet band high-voltage electricity, forms compared with high-intensity magnetic field, metal foil is inhaled
Power, drives warning panel rotation, and warning up, reaches warning effect.
Further, above warning panel rotatable sheet metal make warning panel alert status and non-alert status area
Divide and become apparent from, avoids judging by accident.
Further, indicator light uses light emitting diode, and brightness is high, it is easier to be noted.
To sum up, the utility model has ground connection instruction and charge indicating device, thus the security risk of the utility model is small,
Electric shock accidents is less likely to occur.In addition, the utility model also has structure simple, the characteristics of good warning effect.

Specific embodiment
Below with reference to embodiment, the utility model is described in further detail, but be not intended as to the utility model limit according to
According to.
Embodiment one: a kind of distribution box real-time earthing safety indicating device, the cabinet 10 including line with ground, on cabinet 10
Equipped with indicator light 20, the working power in indicator light 20 and ground line and cabinet 10 is formed into a loop；10 front of cabinet is additionally provided with
Potential indicator 30, potential indicator 30 include transparent shell 31, and the main shaft 32 of several levels is equipped in transparent shell 31；Institute
The periphery for stating every main shaft 32 is connected with nonmetallic warning panel 38, and to be in 32 axis of main shaft remote for the tie point of the two
Side from cabinet 10；The warning panel 38 is equipped with metal foil 33 in the part of 32 or more main shaft, and warning panel 38 is far from cabinet
10 surface is equipped with reflecting coating 34.Reflecting coating 34 is the paint layer with miniature reflecting beads, can paint text.
The lower section of the main shaft 32 is equipped with the stopper 37 cooperated with 38 lower part of warning panel.Stopper 37 is for limiting police
Show rotation angle of the plate 38 under non-alert status, the thickness for reducing shell can reach same effect, but assembling difficulty can increase
Greatly.
The transparent shell 31 is non-metal case.
The indicator light 20 is light emitting diode, and is in series with a protective resistance.
Embodiment two: on the basis of example 1, the top of every main shaft 32 is additionally provided with horizontal secondary shaft 35, and
Secondary shaft 35 is in side of the main shaft 32 far from cabinet 10, and the lower part of secondary shaft 35 is connected with sheet metal 36.
Working principle:
The utility model takes electricity as working power from distribution box, selects indicator light 20 to connect with a resistance, utilizes ground connection
Line forming circuit.After ground path is complete as a result, indicator light 20 shines, and does not otherwise shine, operator can be intuitively known and connect
Ground line condition.
As shown in figure 3, cabinet 10 is not charged, warning panel 38 is only self-possessed.Due to being the surface for being attached to main shaft 32, because
This, under the prevention of gravity and stopper 37, warning panel 38 is in the state tilted down.
As shown in figure 4, cabinet 10 forms stronger magnetic field with high-voltage electricity, metal foil 33 is inhaled, and warning panel 38 is driven to turn over
Turn, in inclination upwards, the warning surface thus with reflecting coating 34 can be seen by front, reach warning effect.
After adding the secondary shaft 35 with unilateral sheet metal, in the case that cabinet 10 charge, sheet metal equally by
Attract rotation, does not influence the rotation of warning panel 38；In the not charged situation of cabinet 10, sheet metal falls, and drives warning panel 38
Go back to the state of non-warning, it is often more important that, this non-alert status is bigger compared with without sheet metal gradient, with alert status
Differentiation becomes apparent from.
The warning panel 38 and sheet metal are all the thin-slab structures of lighter weight, compared with high-intensity magnetic field caused by the high-voltage electricity
In can overturn.
