Description
Technical field
The utility model relates to arc-detection field, especially relates to a kind of novel fault arc-detection serial arc test unit.
Background technology
Along with up-to-dateness improves day by day, the application such as electrical equipment, communication apparatus is more and more, and the loss that electrical fire causes is also increasing; According to statistics; electrical fire is in first of all kinds of cause of fire; in causing the electric reason of these accidents; arc fault is one of chief reason; this is because traditional isolating switch can only be protected the situation of electric leakage, overcurrent and short circuit, and many serious fire failures are caused by the fault electric arc lower than rated current often.
At fault electric arc detection field, the manufacture of carbonized path be very crucial be also a very unmanageable problem, the method for making of current domestic carbonized path, derive from the 40th in U.S. AN/UL1699-2008 standard, the domestic entity and individual that are engaged in this respect research are also the way of quoting in this standard substantially.Specific practice is summarized as: in cable sample, apply 15kV ± 10% high pressure, 10 seconds ON and 10 seconds OFF carry out repeatedly, transformer provides the electric current of 30mA, by the insulation part of cable sample, create carbonization guiding path, but the method exists that the carbonization passage forming is unstable, success ratio is low, need the assistance of high pressure, safe not, and can produce the noxious materials such as a large amount of dioxin, hydrogen chloride, phenyl ring, energy-conserving and environment-protective not.
Summary of the invention
The purpose of this utility model is to provide a kind of novel fault arc-detection serial arc test unit, utilize a kind of New Arc test unit of the present utility model, form stable carbonization passage, shortened the standard testing time, can the in the situation that of different tests electric current, meet the requirement to arc stiffness and time, improve success of the test rate, and safety, environmental protection.
For achieving the above object, a kind of novel fault arc-detection serial arc test unit, comprise cable A and cable B, described cable A outer wrapping one layer insulating A, described cable B outer wrapping one layer insulating B, described cable A includes core A, and described cable B includes core B, and the insulation course of peeling off in the middle of described cable A and cable B is filled with carbon dust.
In the middle of cable A and cable B, cutting exposes part core and is filled with carbon dust, and prevents that by outer wrapping insulation course carbon dust from dropping, can be different according to line current ability to bear, quantize to change carbon dust number and carbon powder particle size.
Because exposed part cable core directly adds carbon dust, obtain with cable the carbon passage conducting electricity, need not insulation course carbonization be formed to carbonization guiding path by the method for high pressure, shortened the standard testing time; Simultaneously, due to exposed part cable core quantifiable filling carbon dust quantity and carbon powder particle size, make analysis and research have clear and definite foundation, and test has more repeatability and science, meet electric arc and control the requirement to duration and intensity.
As improvement, the 15mm place, two ends that described cable A and cable B are filled with carbon dust part is tied with respectively PVC adhesive plaster and glass fibre, and 220V AC power live wire and zero line are accessed respectively in the core two ends of described cable A and cable B.
The utility model patent is filled carbon dust mode by cut exposed core on cable core forms stable carbonization passage and produces electric arc, shortened the test duration, can the in the situation that of different tests electric current, meet the requirement to arc stiffness and time, improve success of the test rate, easy and simple to handle, safety and environmental protection.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
A kind of novel fault arc-detection serial arc test unit as shown in Figure 1, comprise cable A1 and cable B2, described cable A1 outer wrapping one layer insulating A3, described cable B2 outer wrapping one layer insulating B4, described cable A1 includes core A5, described cable B2 includes core B6, and described cable A1 and cable B2 are filled with carbon dust 7 by peeling off adjacent wires intermediate insulating layer.The 15mm place, two ends that described cable A1 and cable B2 are filled with carbon dust 7 parts is tied with respectively PVC adhesive plaster and glass fibre 8, and 220V AC power live wire and zero line are accessed respectively in described core A5 and core B6 two ends.
Serial arc test method detailed process is: 220V AC power live wire and zero line are accessed respectively in core A5 and core B6 two ends, core A5 fully contacts with carbon dust 7 with core B6 exposed part, PVC adhesive plaster and glass fibre 8 prevent that carbon dust 7 from dropping, by heavy current effect, make core A5 and core B6 exposed part and carbon dust 7 form carbonization guiding path and produce electric arc.
Owing to being peelled off insulated wire skin in the middle of two adjacent wires, between exposed wire, directly fill carbon dust 7 and form carbonization passage, need not insulation course carbonization be formed to carbonization guiding path by the method for high pressure, shorten the standard testing time, make test have more repeatability and science, by control, add the difference of carbon dust 7 quality of materials simultaneously, and the size of carbon dust material particle, control arc duration, intensity, meet the requirement of AFDD test.
