Difference
The electric locomotive is a kind of traction equipment for the rail vehicle transportation. The driving force is to use the traction motor to drive the wheel to rotate. The locomotive runs on the track by the friction between the wheel and the rail. This mode of operation, its traction not only by the traction motor (or internal combustion engine) power constraints, but also by the friction between the wheel and rail constraints. Locomotive transport can run the slope is limited, the transport rail slope is generally 3 ‰, local slope can not exceed 30 ‰. Classified according to the structure, there are overhead line electric locomotives and battery electric locomotives.
The overhead line electric locomotive is powered by a pantograph from the circuit. When the electric locomotive is running, the pantograph slides along the overhead line. The power supply method of the overhead line electric locomotive is that the high-voltage cable from the central substation supplies the three-phase AC power of the traction converter, and the transformer is used to step-down the voltage. DC. The positive pole of the DC power supply is connected with the overhead line conductor through the power supply cable. The contact point of the DC power supply becomes the power supply point, and the negative pole is connected with the rail through the return wire. The corresponding contact is called the recycle point. Work, along the orbit of the electric locomotive upper part of the pantograph contact overhead line access to electricity, the lower part of the contact with the wheel and track to form a loop, so that traction motor work, so that electric vehicles traction tub driving.
Battery electric locomotives are generally divided into 2.5T, 5T, 8T, 15T, and several other models. Among them, 2.5T electric locomotives, there are general, safe, explosion-proof special three. Main features: small size, wheelbase is short, small and flexible, up brake fast and reliable, simple structure, easy maintenance, for supporting small and medium-sized mine and roadway transportation. 5T explosion-proof special type electric locomotive, sub-stepless and stepless speed regulation two kinds. I plant in the stepless speed regulation on the first use of thyristor chopper speed new technology. Main features: Machine structure is reasonable, explosion-proof and reliable, smooth start, saving energy. The main technology to achieve the level of similar products at home and abroad. Steering motor locomotive is the use of batteries connected in series with the magnetic field weakening magnetic field. Speed regulation for the 7 level, the car starting a more smooth, no significant impact. Explosion-proof and reliable performance, good quality, simple structure, easy maintenance, welcomed by users. 8T electric locomotive has a variety of models and a variety of voltage levels, and a special type of safety and explosion-proof two. 12T electric locomotives have ordinary type, underground explosion-proof special type and ground engineering car three categories, with traction, high speed, carrying capacity and other characteristics. Explosion-proof special type for an annual output of more than 1.2 million tons of high methane gas mine. Speed control chopper speed or battery string speed two. And can be used double-side cab, overlooking the performance. 15T electric locomotive is designed for large-scale tunnel, subway, water diversion project construction and development of electric locomotives. This locomotive adopts the direct control of resistance speed control: with brake of handwheel, brake of resistance and brake of air. Braking way: Adopting V rubber spring, it can bear vibration, impact in three directions of vertical, vertical and horizontal direction . With traction, high speed, carrying capacity and other characteristics. Of course, battery electric locomotives have more models, such as the three Hong Technology Co., Ltd. produced heavy 30 tons, 40 tons and 55 tons of battery electric locomotives.
