Description
Technical field
The utility model relates to a kind of display device, relates in particular to a kind of 10kV-35kV power circuit ground connection supervisory device.
Background technology
In power industry, transmission line of electricity is in the long-time running process, because factors such as temperature Change, sleet, dust cause the charged generation of cross-arm line-to-ground phenomenon thereby can cause porcelain insulator to puncture.Though the line-to-ground phenomenon can make a big impact to the electrical energy parameter of power supply at run duration, but consider the reliability of line powering, still allow the power circuit of 10kV-35kV to adhere to ground connection operation 2 hours, particularly some circuits high-risk, responsible consumer are particularly like this.The line-to-ground phenomenon takes place during, the electric power first-aid personnel will comprehensively patrol to suspicious faulty line according to the line fault signal that the power scheduling monitor staff sends, but earth fault is difficult to find more difficult discovery when particularly make an inspection tour circuit night.
The utility model content
The purpose of this utility model provides a kind of 10kV-35kV power circuit ground connection supervisory device, and the inspection faulty line time is shortened in the place that can point out the electric power first-aid personnel that earth fault takes place, increases work efficiency.
The utility model adopts following technical proposals:
A kind of 10kV-35kV power circuit ground connection supervisory device comprises housing, is provided with resistance in the housing, and an end of resistance connects cross-arm by lead-in wire, and the other end of resistance connects the live wire end of neon bulb, and the zero line side of neon bulb is by lead-in wire ground connection.
Also comprise anchor ear, housing is by on the fixing online bar of anchor ear.
The Standard resistance range of described resistance is 1*10
8Ω-5.8*10
8Ω.
Be provided with the parallel circuit that a plurality of neon bulbs are formed in the described housing, the two ends of the parallel circuit that a plurality of neon bulbs are formed connect resistance respectively and pass through lead-in wire ground connection.
Described housing is provided with convex lens.
The place that the utility model utilizes neon bulb prompting electric power first-aid personnel that earth fault takes place, simple in structure, with low cost, be applicable to the power circuit ground connection supervision of 10kV-35kV, can point out the electric power first-aid personnel that the place of earth fault takes place rapidly and accurately, shorten the inspection faulty line time, increase work efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use view of the present utility model.
Embodiment
As depicted in figs. 1 and 2, the utility model comprises housing 1, is provided with resistance 2 in the housing 1, and an end of resistance 2 connects cross-arm 4 by lead-in wire 3, and the other end of resistance 2 connects the live wire end of neon bulb 5, and the zero line side of neon bulb 5 is by lead-in wire 3 ground connection; In order to guarantee that neon bulb 5 can reach certain brightness, can form 5 groups of neon bulbs by in parallel a plurality of same common standard neon bulbs 5, simultaneously at housing 1 convex lens 6 are set, by the converging action raising brightness of convex lens 6, are convenient to the electric power first-aid personnel and in time find.The utility model can be by anchor ear 7 with on the housing 1 fixing online bar 8.
The utility model in use, when causing cross-arm 4 charged, because an end of resistance 2 connects cross-arms 4 by lead-in wire 3, the other end of resistance 2 is by neon bulb 5 and lead-in wire 3 ground connection when porcelain insulator 9 is breakdown; Porcelain insulator 9 punctures the high-tension electricity of revealing the back and will discharge by neon bulb 5, and this moment, neon bulb 5 will be luminous, and earth fault takes place prompting electric power first-aid personnel herein.Direct at 0.6mA-1mA for 3 electric currents that guarantee to go between, the Standard resistance range of resistance 2 is 1*10
8Ω-5.8*10
8Ω.
The utility model is simple in structure, and is with low cost, is applicable to the power circuit ground connection supervision of 10kV-35kV, and the inspection faulty line time is shortened in the place that can point out the electric power first-aid personnel that earth fault takes place rapidly and accurately, increases work efficiency.
