Online deicing device for magnetic suspension contact rail and deicing method thereof

Abstract

The invention discloses an online deicing device for a magnetic levitation contact rail and a deicing method thereof. The online deicing device comprises an energy storage capacitor bank, a controllable switch, a coil, an energy taking circuit and an intelligent control device. The coil is wound into a rectangular single-layer cake-shaped structure and is packaged in a groove of a flat surface of a metal substrate; the coil is in tight clearance contact with the side surface of the magnetic levitation contact rail under the external acting force; the deicing method comprises the steps that when the magnetic levitation locomotive runs, the intelligent control device controls the discharging frequency of the energy storage capacitor bank to the coil, so that the coil generates a high-amplitude pulsed magnetic field; the magnetic levitation contact rail generates an eddy current on the surface adjacent to the coil; a pulse repulsive force is generated between the coil and the contact rail through a pulse magnetic field excited by eddy currents on the surfaces of the coil and the contact rail, mechanical waves formed by the pulse repulsive force spread in the contact rail to crush ice, and the purpose of deicing is achieved. According to the invention, online deicing can be carried out on the contact rail in the running process of the train, and stable operation of the maglev train is ensured.

Description

technical field [0001] The invention relates to the field of deicing contact rails, in particular to an online deicing device and a deicing method for magnetic suspension contact rails. Background technique [0002] Maglev is an important public transportation express line in the city, and ice in winter seriously affects the safe operation of maglev. Under the conditions of ice-covered environment in winter, the maglev track and contact track exposed to the natural environment continue to be covered with ice under the action of wind, especially under the environmental conditions of freezing rain, the icing of the contact track grows rapidly. The maglev contact rail provides power supply for the operation of the maglev train. The power supply adopts the sliding brush power receiving method. Once the contact rail is covered by ice, the maglev locomotive cannot receive power through contact, and when the ice layer is thin, it is easy to produce bad contact and form an arc. Dis...
