(www.xahaite.com) is the Xi'an high-quality certified company Commercial Union, with Hite and other brands, has a good reputation, honesty, service-oriented "business alliance Service" icon on the page We will be happy to serve you! Classification electric locomotive electric locomotive by using the occasion can be divided into: mining locomotive and mainline electric locomotives types of electricity. Mining electric locomotives use more direct system, power, and speed is generally smaller than the main line electric locomotives Xi'an Railway Electric Power Company, the habit of sticking by locomotive weight classification, such as 150 tons of Xi'an electric locomotive Electric Company, 100 tons, 85 tons, 70 tons, 60 tons, 50 tons, and lighter grades. Larger tonnage for standard gauge line locomotives, locomotive lighter and more for a variety of narrow gauge lines. Route electric locomotives use can be divided passenger electric locomotives, freight electric locomotive electric locomotive company in Xi'an, cargo-passenger electric locomotives and electric locomotives shunting four. According to the current system of electrified railway used to classify trunk electric locomotive can be divided into two categories. Catenary electric locomotive electric locomotive itself, without prime mover, by receiving the catenary current sent as an energy source, the locomotive wheels driven by a traction motor. Electric locomotives with power, high thermal efficiency, fast, strong and reliable operation overload main advantages, and do not pollute the environment, especially for the busy railway transport and tunnel more steep slope of the mountain railway. Electric locomotive is to obtain power from contact with the Internet, catenary supply of electric locomotives with DC and AC current two. Because of different current system, electric locomotive used are not the same, divided into straight - DC electric locomotive, AC - DC electric locomotive, AC - DC - AC locomotives categories. DC - DC electric locomotive using DC power supply system, traction substations equipped with rectifier convert three-phase alternating current into direct current electric locomotives Hou Xian, and then sent to the contact line. Therefore, the supply of DC electric locomotive can be obtained directly from the contact line of DC series excitation traction motor, simplifying the device locomotive. Disadvantages DC catenary system voltage is low, typically 1500V or 3000 V, contact wire requires very thick, to consume a large amount of non-ferrous metals, increased construction investment.
