Abstract
The utility model discloses a kind of railway snow melting cable, comprise oversheath and be in the snow melt core unit in oversheath, described snow melt core unit comprises heating heart yearn and is coated on the snow melt core insulation on heating heart yearn, monitoring cable core unit is also provided with in described oversheath, this monitoring cable core unit comprises monitoring heart yearn and is coated on the monitoring core insulation on monitoring heart yearn, be outside equipped with separator at described snow melt core unit and monitoring cable core unit, between separator and oversheath, be provided with high-strength armour.The railway snow melting cable of this utility model can not only have snow melting function, can also prevent snow melt cable from being cut the generation of accident that causes.
Description
Technical field
The utility model relates to a kind of heater cable, particularly relates to a kind of railroad track snow melt heater cable.
Background technology
Railway is the main artery of national economy, plays a part very important in the development of national economy, once there is security incident, consequence is hardly imaginable.In the winter time, owing to snowing or sleet, track switch and turn-out track equipment very easily cause accumulated snow or freeze, and cause it cannot normal conversion, thus form the major hidden danger affecting traffic safety.In order to prevent track switch and turn-out track equipment accumulated snow from freezing, guarantee driving safety, electric heating melting snow on turnout junction technology is widely used.
One of core of electric heating melting snow on turnout junction technology is heating element, and the snow melt cable as heating element plays key effect in electric heating melting snow on turnout junction technology.Along with developing rapidly of the special railway construction of High-Speed Passenger, the use amount of snow melt cable is also increasing, because snow melt cable adopts nonferrous materials as conductor, economic worth is higher, the phenomenon be cut is had to occur time in use procedure, if fail to realize in time, track switch and turn-out track equipment are frozen in and can not fulfil assignment, and will cause a serious accident.
Utility model content
For the above-mentioned deficiency existing for prior art, technical problem to be solved in the utility model is to provide a kind of railway snow melting cable, and it can not only have snow melting function, can also prevent snow melt cable from being cut the generation of accident that causes.
In order to solve the problems of the technologies described above, a kind of railway snow melting cable of the present utility model, comprise oversheath and be in the snow melt core unit in oversheath, described snow melt core unit comprises heating heart yearn and is coated on the snow melt core insulation on heating heart yearn, monitoring cable core unit is also provided with in described oversheath, this monitoring cable core unit comprises monitoring heart yearn and is coated on the monitoring core insulation on monitoring heart yearn, be outside equipped with separator at described snow melt core unit and monitoring cable core unit, between separator and oversheath, be provided with high-strength armour.
In said structure, owing to being also provided with monitoring cable core unit in described oversheath, this monitoring cable core unit comprises monitoring heart yearn and is coated on the monitoring core insulation on monitoring heart yearn, then railway snow melting cable of the present utility model being also provided with monitoring cable core unit in oversheath except being provided with snow melt core unit, snow melting function can not only be realized like this, and after generation robber cuts event, because monitoring cable core unit can be made pilot signal interrupt by cutting off simultaneously, electric heating melting snow on turnout junction control system will the exception of Timeliness coverage snow melt cable, related personnel is reminded to check in time, thus prevent snow melt cable from being cut the generation of the accident that may cause, the monitoring core insulation be coated on monitoring heart yearn ensure that monitoring heart yearn is not by the interference of external signal, improve the accuracy of monitor message, again owing to being outside equipped with separator at described snow melt core unit and monitoring cable core unit, high-strength armour is provided with between separator and oversheath, then high-strength armour improves compression strength compared to common armour, better to the protected effect of snow melt core unit and monitoring cable core unit, separator be arranged so that snow melt core unit and monitoring cable core unit directly do not contact with high-strength armour, snow melt core unit and monitoring cable core unit is prevented to be extruded impaired by high-strength armour, extend useful life, also ensure that the lasting realization of the snow melt of this cable and monitoring function.
A kind of preferred implementation of the present utility model, described snow melt core element number is at least one.Adopt this execution mode, according to the snow melt core unit of use occasion different choice varying number, can reduce costs while meeting snow melt instructions for use.
Another kind of preferred implementation of the present utility model, institute's monitoring cable core unit quantity is two.Adopt this execution mode, two monitoring cable core units can form monitoring loop easily, once monitoring cable core unit is cut-off will obtain feedback information in time, to be quick on the draw and structure is simple.
Another preferred implementation of the present utility model, described snow melt core element number is seven, stranded on the snow melt core unit being positioned at heart portion have six roots of sensation snow melt core unit, and monitoring cable core unit is uniform is arranged at the outside being positioned at heart portion snow melt core unit.Adopt this execution mode, seven snow melt core unit can meet the snow melt heating power requirement of track switch and turn-out track equipment under usual climate condition, and six roots of sensation snow melt core unit be stranded in heart portion a snow melt core unit on whole snow melt cable can be made to have higher pliability, be convenient to installing and using of snow melt cable.
The further preferred implementation of the utility model, described high-strength armour is two button armours.Adopt this execution mode, two button sheathed structure is higher than single button sheathed structures or other sheathed structure tension, compression strength, and flexibility, retractility are also better, can meet the snow melt instructions for use of high speed railway of passengers' private line well.
Another further preferred implementation of the utility model, described oversheath is low-smoke and halogen-free flame retardant polyolefin jacket.Adopt this execution mode, sheath is that low-smoke halide-free fireproof composite polyolefine material is formed, environment-protecting asepsis, ageing-resistant and UV resistant and other irradiation behaviour high, under severe field environment for use, cable can effectively be ensured useful life.
