Description
Technical field
The utility model relates to field of cable technology, more precisely relates to a kind of cable of active Short Circuit withstand.
Background technology
Often meeting breaking out of fire because of artificial origin or natural calamity among social production life; immeasurable loss is caused to the people's lives and property; especially power consumption equipment and electric wire become main fire source especially; line short not only produces directly infringement but also easy initiation fire to power consumption equipment, and the line short caused in a fire more can accelerate spreading of the intensity of a fire.Cable does not in the market have the safeguard measure of fire-proof or against short-circuit usually; the combustibles such as general employing plastic cement are as the protective layer of cable; this easily makes adjacent cable heated and sticks together; cause short circuit and damage power consumption equipment or initiation fire; when breaking out of fire, this cable more can accelerate spreading of the intensity of a fire.
As can be seen here, current cable still Shortcomings, exists and promotes room for improvement.
In view of the deficiency that current cable exists, the design people is based on being engaged in this type of product design manufacture for many years, long-pending have abundant professional knowledge and practical experience, consults pertinent literature and mechanical structure innovation example, actively in addition innovation research, to designing a kind of novel cable structure, current cable can be improved, make it have more competitiveness and practicality, through constantly studying, designing, and through repeatedly studying sample and after improving, finally creating the utility model of true tool use value.
Summary of the invention
Technical problem underlying to be solved in the utility model is, overcome the deficiency that current cable exists, and the cable preventing short circuit between cable in a kind of fire is provided, overcome the easy initiation fire of existing cable or the problem be short-circuited of being heated, thering is provided a kind of adopts burning can ceramic plastic cement support bar carrying cable inner core, adopt thin wire winding layer parcel low-melting glass powder bed, then the cable core arrangement of glass fibre lapping layer and electric conductor is inwardly wrapped up successively, when have an accident or fire time, the electric conductor beam conduction of internal layer can be ensured and do not cause short circuit.
The utility model solves its technical problem underlying and is achieved through the following technical solutions, comprising burning according to the cable of active Short Circuit withstand that the utility model proposes can ceramic plastic cement support bar, cable inner core and external sheath layer, cable inner core comprises electric conductor, glass fibre lapping layer, low-melting glass powder bed and thin wire winding layer, glass fibre lapping layer parcel electric conductor, low-melting glass powder bed parcel glass fibre lapping layer, thin wire winding layer is that thin wire is closely wound around and rearranges, thin wire winding layer parcel low-melting glass powder bed, burning can ceramic plastic cement support bar cross section is triangular in shape in its natural state, cable inner core have 3 at least and extruding be arranged in burning can 3 sides of ceramic plastic cement support bar, external sheath layer presses the cable inner core of parcel arrangement.
Better, above-mentioned burning can the cross-sectional area of ceramic plastic cement support bar cross section in its natural state be 1.5 times of electric conductor cross-sectional area to 3 times.
Better, the diameter of the thin wire of above-mentioned thin wire winding layer is 0.01 millimeter to 0.05 millimeter, and the thickness of thin wire winding layer is 0.02 millimeter to 0.1 millimeter.
Better, above-mentioned burning can ceramic plastic cement support bar in its natural state cross section be equilateral triangle.
Better, the thickness of above-mentioned low-melting glass powder bed is that one of percentage of electric conductor diameter is to 1/10th.
Better, the thickness of above-mentioned glass fibre lapping layer is 1.1 times of the thickness of low-melting glass powder bed to 2 times.
The cable of active Short Circuit withstand described in the utility model, its beneficial effect produced is: adopt burning can ceramic plastic cement support bar carrying cable inner core, under normal usage, because burning can have certain toughness by ceramic plastic cement support bar, add the buffering of cable to external pressure, when being heated in accident, burning can form ceramic state solid by ceramic plastic cement support bar, play the effect of the cable inner core supporting same cable inside, adopt thin wire winding layer parcel low-melting glass powder bed, when external sheath layer suffers breakage, the thin wire winding layer of adjacent cable inner core contacts with each other and is short-circuited, because wire is very thin, resistance is larger, cause higher caloric value, low-melting glass powder bed is melted, thin wire also melts because of self-heating simultaneously, thin wire has melted rear short circuit phenomenon and has disappeared, glassy solids is become after the low-melting glass cooling be melted, play the effect of isolation adjacent cable inner core and parcel glass fibre lapping layer, because glassfiber insulation is good, thermal endurance is strong, corrosion resistance is good, mechanical strength is high, ensure that the beam conduction of cable inner core inner layer conductive body, make this cable also can beam conduction in fire or the stronger accident of some other destructivenesses, add the scope of application of cable, improve the security performance of cable.In production application, quantity and the arrangement mode of the cable inner core wrapped up in external sheath layer can be adjusted according to actual conditions, also the thickness of thin wire and the quantity of winding in thin wire winding layer can be adjusted according to the thickness of low-melting glass powder bed, meet thin wire because the caloric value of short circuit generation just can make the fusing of low-melting glass powder major part before self fusing, cooling forms glassy solids then.
