Abstract
The utility model provides a fireproof electric wire performance test device comprising a pedestal and a test box which is installed on the pedestal. The test box is internally provided with a vertical plate. The test box is divided into a detection chamber and a spray chamber by the vertical plate. The detection chamber is internally provided with an electric wire supporting base and a discharging device. The electric wire supporting base is covered by insulating material. The discharging device is installed above the electric wire supporting base. The spray chamber comprises a spray pipe which is installed on the side wall of the spray chamber, and one end of the spray pipe is communicated with tap water. The spray pipe is provided with a spray gun. The electric wire supporting base comprises two hollow shafts which are arranged in parallel, supporting frames and a guiding wheel. Spacing distance between the two hollow shafts is 1cm. The two hollow shafts are fixed on the supporting frames via bearing bases and driven by a motor. The hollow shafts are provided with oil outlet holes. The guiding wheel is arranged between the two hollow shafts and driven by a second motor.
Description
Technical field
The utility model relates to a kind of flame-proof wire performance testing device.
Background technology
In recent years, cause that the case of fire is of common occurrence due to electric wire spontaneous combustion, based on above situation, people develop surface insulation layer and have the flame-proof wire of higher kindling point.After flame-proof wire is produced, usually need electric wire to carry out flammability test, judge the fire protecting performance of electric wire by combustion method in the past, but, research is found by experiment, if do not having completely under extraneous flame or strong radiation event, spontaneous combustion can not occur the normal electric wire using.In following situation, can there is spontaneous combustion in electric wire, and likely constantly spread initiation fire:
In the kitchen in old room long neglected and in disrepair, the BLV that open-wire line lays, a large amount of greasy dirts and dust have been gathered in its surface.Due to the covering of greasy dirt, electric wire surface insulation resistance is reduced, leakage current increases gradually, until leakage current is even as big as making electric wire surface occur burning, flame, also with regard to this rapid spread, even if now power supply cuts off automatically (as leakage relay tripping operation or blown fuse), also cannot stop flame to continue expansion, in short time, flame spreads all over other combustible object, allows into fire at once.
Therefore in the time of test flame-proof wire performance, test by the method for burning, its testing result is often too unilateral.
Utility model content
Problem to be solved in the utility model is to provide a kind of proving installation of flame-proof wire.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of flame-proof wire performance testing device, comprise base and be arranged on the chamber on base, in described chamber, be provided with riser, chamber is divided into sensing chamber, spray chamber by this riser, in described sensing chamber, be provided with electric wire supporting seat, electric discharge device, this electric wire supporting seat is coated with insulating material, and described electric discharge device is arranged on electric wire supporting seat top; Described spray chamber comprises shower, and shower is arranged on the sidewall of spray chamber, and its one end is communicated with tap water, and described shower is provided with spray gun.
Further, described electric wire supporting seat comprises tubular shaft, support, the angle sheave of two parallel placements, two tubular shaft spacing 1cm, and two tubular shafts are fixed on support by bearing seat, and this tubular shaft is driven by motor, and described tubular shaft is provided with oil outlet; Described angle sheave is positioned at two tubular shaft belows, and this angle sheave is driven by the second motor.
Further, described angle sheave is positioned at tubular shaft below 1-2cm.
Advantage and the good effect that the utlity model has are: the utility model can detect by analog kitchen environment, it detects the fire protecting performance that test findings can reflect flame-proof wire really, and this apparatus structure is simple, easy to operate, cheap for manufacturing cost.

Embodiment
Embodiment 1:
The present embodiment discloses a kind of flame-proof wire performance testing device, comprise base 1 and the chamber that is arranged on base, this chamber is divided into sensing chamber 2, spray chamber 3 by riser, in sensing chamber, be provided with electric wire supporting seat 4, electric discharge device 5, described electric wire supporting seat is coated with insulating material, it comprises tubular shaft 9, support 10, the guide piece 11 of two parallel placements, tubular shaft is driven by motor and is fixed on support by bearing seat, two tubular shaft spacing are 1cm, oil is housed in tubular shaft, and tubular shaft is provided with oilhole 12; Described guide piece is arranged on two belows, tubular shaft gap place.
Further, this guide piece comprises that described push-rod electric machine one end and the second support are fixed by the second motor-driven angle sheave 13, the second support 14, push-rod electric machine 15, and the other end and angle sheave are fixed.
Further, described angle sheave is positioned at tubular shaft below 1-2cm.
Further, be provided with shower 6 in described spray chamber, shower is arranged on the sidewall of spray chamber, and this shower one end is communicated with running water pipe, is also provided with spray gun 7 on this shower.
Further, described riser is provided with sprocket hole 8, and this sprocket hole is on the extended line in gap between two tubular shafts.
In the time carrying out performance test, the flame-proof wire that needs are detected is put into sensing chamber, start the first motor, make it drive tubular shaft to rotate, after flame-proof wire is stained with oil, open electric discharge device, electric discharge device produces electric spark the flame-proof wire that shocks by electricity, increase gradually electric current, until ultimate current value is now recorded in the burning of the insulation course of fire-retarding conducting line; Start electric pushrod, angle sheave is contacted with the flame-proof wire of detection, then, start the second motor, angle sheave rotates, and now, fire-retarding conducting line is transported to spray chamber by guide piece, cooling flame-proof wire.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model scope, within all should still belonging to this patent covering scope.
