Abstract

The invention relates to a power supply device, in particular to a power supply device of a mobile flash rail welding machine, and solves the defects and problems of an existing movable flash rail welding machine by adopting a diesel generator set as a power supply device. The power supply device comprises a storage battery pack, a super capacitor bank, a bidirectional DC/DC converter and a welding main inverter, the super capacitor bank is connected with one end of the bidirectional DC/DC converter, the other end of the bidirectional DC/DC converter is connected with the input end of the welding main inverter, the output end of the storage battery bank is connected with the input end of the welding main inverter through an isolation switch KM2, and the output end of the welding main inverter supplies power to the movable flash rail welding machine. The device avoids the oil fume pollution and is particularly suitable for welding underground rails, such as subways, etc., enables the economic benefits of users to be improved, generates noise hardly, and enables the service life to be prolonged and the maintenance cost to be reduced.

Description

technical field [0001] The invention relates to a power supply device, in particular to a power supply device for a mobile flash rail welding machine. Background technique [0002] China's high-speed railway operation mileage has ranked first in the world, and one of the key links to ensure the safe and comfortable operation of high-speed railways is track welding technology. At present, there are three commonly used rail welding methods in high-speed railway construction: flash welding, gas pressure welding, and thermite welding. Due to its advanced technology, good welding quality, and high operating efficiency, flash welding has been widely used in the construction of seamless lines such as high-speed railways, urban rails, and subways. [0003] The existing mobile flash welding machine adopts diesel generator set as power supply device, figure 1 Shown is the technical scheme of the existing diesel generator set for power supply to the rail welding machine: the diesel g...
