A superpower convert device with adjustable integrated combine parameters

Abstract

A superpower convert device with adjustable integrated combine parameters comprises a three-layer truss and an auxiliary switch block sequentially mounted on the three-layer truss from top to bottom,An inductive reactor block and a capacitor block are connected by flanges between adjacent two-layer trusses, a resin bucket support is installed below the bottom truss, and the auxiliary switch blockcomprises a plurality of thyristor assemblies, wherein the plurality of thyristor assemblies form a matrix block in the form of a cage symmetrical distribution through a plurality of connecting rows,and lead-out wires are arranged at the upper ends of the connecting rows; The inductance reactor block is composed of a plurality of inductance matrix blocks in series or in parallel, and an insulating plate is arranged between adjacent inductance matrix blocks. The invention longitudinally arranges the modules required in the converter circuit into the fixed truss support, and ensures that all the connections are on the same horizontal plane so as to facilitate the serial-parallel connection between the sub-modules. The design is not only quick and efficient, but also saves some unnecessarycosts due to the parameter changes.

Description

technical field [0001] The present invention relates to the technical field of quench protection system for superconducting magnet devices, in particular to an integrated combined parameter-adjustable ultra-high power converter device, the main function of which is to provide directional pulse current to the main circuit when a superconducting magnet is quenched , to create an artificial current zero-crossing point, so that the main circuit switch can be quickly turned off by zero-crossing, and the energy in the superconducting magnet can be quickly transferred to the discharge resistor for energy consumption, so as to ensure that the superconducting magnet will not be quenched for too long state resulting in irreversible damage. Background technique [0002] 1. The function of the quench protection switch system is to quickly transfer the energy in the magnet to the discharge resistor by relying on the high-power DC switch when a quench event occurs in the superconducting m...

[0004] 3. Since there is no natural current zero crossing point for DC current, it is a big difficulty to shut off under high current

This will lead to an increase in experimental costs and a waste of resources
