Embodiment Construction

[0016] The segmented power supply linear motor used in catapults and other equipment is a special device with a multi-segment structure. When the equipment is working, multiple (the present invention is set to 2n) linear motors powered by segments work synchronously. Each linear motor is divided into several sections along the horizontal length direction, and the 1# stator, 2# stator, 3# stator, etc. of the linear motor are arranged in sequence. The structure and electrical characteristics of each linear motor are exactly the same, and there is no electrical connection between them. The stators of each motor are connected by power supply busbars, and the number of busbars depends on the phase number and working mode of the linear motor. For an m-phase linear motor that works in k-segment simultaneous energization, the required number of busbars is m·(k+1) busbars.

[0017] For example, if three phases of linear motors are energized at the same time, there are four groups of ...

Abstract

A power supply busbar for segmental power supply linear motors belongs to a power system device designed to meet electromagnetic compatibility requirements, and solves the electromagnetic radiation problem of general power supply busbars. The invention includes several groups of composite busbars, each group of composite busbars includes two independent busbars placed parallel to each other, and the outer layer of the busbars is wrapped and sealed with insulating material and pressed into shape. Two independent busbars respectively supply power to two synchronous linear motors, are connected to the stators of the two linear motors in a mirrored connection mode, and are energized in a mirrored power-on mode, so that the two busbars are connected in the working process. The energized lengths are equal and the current directions are opposite. The invention can greatly reduce the electromagnetic radiation generated by the power supply busbar in the working process, reduce the impact on adjacent equipment and personnel, and does not need to add other equipment, which is safe, reliable and easy to implement.

Description

technical field [0001] The invention belongs to the field of electromagnetic compatibility design of a power system, and in particular relates to a power supply busbar used by a segmented power supply linear motor, which solves the electromagnetic radiation problem of a general power supply busbar. Background technique [0002] Segmentally powered linear motor is the core device of equipment such as catapults, and its function is to convert electrical energy into kinetic energy of the mover. When equipment such as a catapult is working, a plurality of (the present invention is set to 2n) linear motors work synchronously to convert electric energy into kinetic energy of the same mover, so that the mover can obtain extremely high speed. [0003] The linear motor with segmental power supply is generally powered by a power supply busbar. The power supply busbar is a long straight rigid wire, ranging in length from a few meters to hundreds of meters, and the cross-section can be...
