As shown in Figure 1-Figure 3, a kind of ground fault warning panel provided by the utility model, including warning panel main body, it is described
Warning panel main body includes support portion 100 and warning part 300；The support portion 100 and the warning part 300 form the warning panel
Main body.
In some embodiments, ground fault warning panel is made of support portion 100 and warning part 300, is generally being used
When, ground fault warning panel is mounted on to the mounting plate 600 of ground line and the tower leg main material angle steel or steel pipe tower leg of shaft tower
On earth plate, when shaft tower fault current flows into the earth by ground line, warning part 300 is melted, leaves it obviously
Ablation trace, thus enable route operation maintenance personnel easily determine failure shaft tower.
Based on the above embodiment on basis, further, it is provided in the warning panel main body for warning panel main body
The perforation 200 of installation.
Based on the above embodiment on basis, further, the perforation 200 is located in the warning part 300, and described
Warning part 300 extends to outside the warning panel main body.
The connection of general warning panel main body and tower leg, which uses, to be spirally connected, when fault current is flowed on ground line from shaft tower
It waits, electric current can be flowed through from fixing bolt 800, and fixing bolt 800 is passed through from the perforation 200 in warning panel main body, is generated at this time
A large amount of heat can make perforation 200 around the warning part 300 formed by low-melting alloy melt, to generate apparent excessively electric
Ablation trace is flowed, so that route operation maintenance personnel be made easier to find.
Based on the above embodiment on basis, further, the warning part 300 includes fusion zone 301 and guiding region
302, the guiding region 302 is connected with the fusion zone 301, and the support portion 100 be provided with melt outflow melt out mouth
500, the fusion zone 301 melts out mouth 500 positioned at described.
The fusion zone 301 of warning part 300 is contacted with fixing bolt 800, and fault current guarantees through fixing bolt 800
It is flowed into ground line, fault current may not be can guarantee due to other reasons elsewhere and pass through.
When mounting plate 600, warning panel main body and tower leg are installed together by fixing bolt 800, perforation 200
Neighbouring fastening pressure is big, contacts, it is ensured that warning part 300 can be melted.
Based on the above embodiment on basis, further, there are two perforation 200 for setting in the warning panel main body, often
One perforation 200 is separately positioned in the warning part 300, and two warning parts 300 are not attached to.
In some embodiments, there are two perforation 200 for setting in warning panel main body, according to actual needs, in warning panel master
One or more perforation 200 can be set on body, each perforation 200 is arranged in warning part 300, when fault current stream
To when ground line, it is ensured that at least one warning part 300 is melted, and is generated apparent electric current ablation trace, is easy to by O&M
Personnel's discovery.
Based on the above embodiment on basis, further, 100 material of support portion is zinc-coated flat steel sheet.
Based on the above embodiment on basis, further, 300 material of warning part is low-melting alloy.
Low-melting alloy refers to fusing point in 300 DEG C of metals and its alloy below, usually by low melting points such as Bi, Sn, Pb, In
Metallic element composition.
The melting temperature of low-melting alloy melt material is generally 60~200 DEG C.Melt be using a certain proportion of bismuth,
The elements such as cadmium, tin, lead, dysprosium, indium form different cocrystallizing type low-melting alloys as main component.
Fault current crosses the electric current of tens KA within several hundred milliseconds of times, and the heat of generation is enough to keep low-melting alloy molten
Change, to generate apparent electric current ablation trace.
In some embodiments, 100 material of support portion of warning panel main body is generally identical as the tower leg material of head tower, uses
Zinc-coated flat steel sheet, when fault current flows through, support portion 100 is not melted, and support portion 100 forms one and stable melts out
Mouth 500, after warning part 300 is melted by fault current, melt can be flowed out from mouth 500 is melted out, and form apparent electric current ablation
Trace serves as a warning.
Based on the above embodiment on basis, further, mouth 500 is melted out there are two settings on the support portion 100, and
The two sides that the support portion 100 is arranged in mouth 500 are melted out described in two.
In order to keep electric current ablation trace more obvious, different sides is arranged in the mouth 500 that melts out on support portion 100,
To which the electric current ablation trace generated is located at different positions, it is easier that operation maintenance personnel is allowed to find in this way.
As shown in Figure 4 and Figure 5, the utility model also provides a kind of grounding wire component, including ground fault described above police
Show plate and ground line,
The ground line includes ground line main body 700 and mounting plate 600, is mounted in described 700 one end of ground line main body
On mounting plate 600,
The mounting hole 400 corresponding with the perforation 200 in the ground fault warning panel on the mounting plate 600.
In some embodiments, grounding wire component includes ground fault warning panel and ground line, the ground line master of ground line
Body 700 is typically welded on mounting plate 600；In the mounting hole 400 on mounting plate 600 and the perforation 200 1 in warning panel main body
One is corresponding.
In order to more beautiful, general warning panel main body is identical as 600 main body size of mounting plate.
It further include fixing bolt 800 further, the fixing bolt 800 is used for based on the above embodiment on basis
Ground fault warning panel is mounted between mounting plate 600 and atural object waiting 900.
In order to facilitate replacement ground fault warning panel, the mounting plate 600 of ground line will be grounded event by fixing bolt 800
Barrier warning panel is mounted between mounting plate 600 and column foot, the convenient ground fault warning panel after failure, more renewed.
Atural object 900 waiting can be shaft tower or other desired power equipment.
The support portion 100 of ground fault warning panel provided by the utility model and the warning panel main body of grounding wire component can
Play the role of support, guarantee when warning part 300 melts, melt can be flowed out from mouth 500 is melted out, and it is aobvious to carry out alarm
Show, is conducive to operation maintenance personnel and finds significant change by naked eyes in tour, to play the role of failure warning.
Ground fault warning panel uses simple and reliable metal structure, does not change original electric connecting element, is only clamped in
It is novel in design practical between original connection, meet demand, fills up one blank of technical field.
