At present, China's railway system, the work of Kiyoshi site entirely rely on manual to complete. With the sharp acceleration of domestic railway running artificial way to enhance and improve the railway Kiyoshi automation level of passenger safety requirements of punctuality, the railway system is currently used can not meet the requirements. So domestic railway turnout snowmelt heating strip born out of the system. The company tech talent, absorb foreign advanced production technology of the railway turnout snowmelt heating, combined with China's railway facilities and climatic conditions of the new self-developed turnout snowmelt system; high-tech oriented requirements, turnout efforts with the conversion snowmelt each system, independent research and development of railway turnout snowmelt system - turnout snowmelt heating strips and remote console. Applies to all of our railway turnouts automatic snow, winter snow railway turnouts ensure reliable conversion to provide guarantees for the safety of railway traffic punctuality. Railway Points Heating System is one of the auxiliary equipment railway turnout conversion equipment, the use of the basic rail of turnout at the waist, rail slope and tow point at fixed clamp flat ribbon straight, U-shaped and L-shaped electric heating strip tight solid mounted, and supporting control equipment, through the acquisition of rail temperature, air temperature and snowfall information, automatic control turnout heating circuit work, and remote monitoring, dynamic monitoring of the ambient temperature, the rail temperature, snow condition, heating time, heating circuit status parameters. The system installed in the railway track turnout basic slip headboard electric heating strips, rain and snow sensor, temperature sensor and remote control turnouts systems (indoor electrical control cabinet) via a cable connection lines and other components. When snowfall occurs, automatically or manually start the electric heating system circuit snow, melts between the switch rail and basic track, slippery snow headboard, to ensure the normal conversion turnout. One. AQRX series railway turnout snowmelt electric heating strip Features (1) electric heating strip is a nickel-chromium stainless steel body shell for heat transfer, built-in optimization of nickel chromium resistance wire as a heat source, between the electric wire and the shell is filled with a dense mineral magnesium oxide thermal insulation layer; (2) the use of mineral insulated heating cable proprietary sealing technology; ensure that snowmelt heating strip electrical performance drop of no more than 20 percent a decade; suitable for railway track turnout and basic heating requirement, the pressure can be up to 2500V, no breakdown; (3) snowmelt heating strip vibration resistant, impact-resistant, corrosion-resistant features. The trailing end of the lead cable to increase the wear resistance of the polyurethane sheath strong resistance, tear resistance and chemical resistance, as well as oil, grease, gasoline, water, ozone, ultraviolet radiation, hydrolysis and microbes. (4) The system is in the process of installing and using the full implementation of the railway system of national standards, the turnout at the installation of high efficiency electric section shall not destroy the original turnout of any parts, components, ensure rail mechanical strength is not affected. Quick and easy installation, does not influence the operation of the railway. (5) The system has a reliable safety and security system equipment, and railway signaling systems and other electrical systems without any interference, without affecting its normal work. II. Main Specifications (1) Power supply voltage: 380V / 220V 50Hz or customized according to the user's requirements (2) at ambient temperature T = -40 ℃, wind speed = 10m / s, the system can keep turnout heating surface temperature> 2 ℃. (3) at ambient temperature T = -30 ℃, the snow melting capacity of 10mm / 12h (snow blizzard of meteorological expressed) that is able to maintain with the melting snow falling over, leaving snow and ice; (4) across the snow electricity heated bar at rated voltage, ambient temperature 35 ℃, the maximum surface temperature <400 ℃, the actual surface temperature during snowmelt <180 ℃. (5) Insulation resistance ≥500MΩ. (6) The compressive strength> 2500V. Protection class: IP65 (7) design life of> 10 years. Three. Electric heating strip heating installation instructions of the general installation, first install fasteners snowmelt heating strips to be used by loaded onto the tracks, for security purposes, a special emphasis must be placed in high-strength bolt connector installation ; therefore, the screw wrench to be tightened to 68 Nm of torque, the inspection of Okuzaki Technology flat oval cross-section of a heated bar, choose the appropriate specification model based on the principle of resistance heating, in line with the specific process requirements of normal heat output about 300 W / m. By clamping bracket and each article will snowmelt heating connector installation. And snowmelt heating bar reaches 200 super sharp derailed and 600 mm. IP protection in order to achieve the requirements of 65 rail operators, Okuzaki snowmelt heating strips, each heating element has a single rail connectors, flexible pipe connections. The appropriate choice of the fixed and the heating element forming with the cable connection, connector, heater and by suitable fasteners to the mounting on the tracks, in order to ensure good heat transfer, but the heating element does not obstruct the longitudinal direction when heated in the guide rail expansion, the cable connector is mounted on a fixed rail, connector thaw heated bars fixed rail foot in the longitudinal direction, and to prevent migration of the entire heating element. Further, in the junction box installed easily generated solid metal compound, and therefore, according to the heating strips mounted on the rail. Three technical parameters .. snowmelt heating strips analytical models Model: AQRX1-Z200-530-L (1) AQRX1-- Okuzaki snowmelt bar section is 13.5 mm X 5.5mm; AQRX2-- Okuzaki snowmelt bar section is 15.5 mm X 5.5mm ( 2) Z200-- represents a straight handle, power 200W, U200, said U-shaped handle power 200W (3) 530-- snowmelt length of the bar represents 530 (MM), (4) L-- cable outlet length (6M; 8M / 10M / 12M / 14M), does not specify the length of the wires are 10M. Four. Environment 1. railway turnout snowmelt electric heating system is suitable for all types of electrified and non-electrified traction zone turnout. 2.
