Embodiment Construction

[0035] The present invention completes the design of mechanical properties by considering the factors of the following aspects:

[0036] (1) material selection;

[0037] The saturable reactor mainly adopts a structure formed by coupling and assembling a coil made of an aluminum tube and an oriented silicon steel sheet. The insulating material is mainly epoxy resin, which is used for casting the coil of the saturated reactor, and it needs to meet certain insulation requirements and thermal characteristics requirements. As for the coil of the saturable reactor, since the inside flows through the cooling fluid, the cooling fluid is a mixture of water and ethylene glycol. In order to ensure the reliability of the saturable reactor within the service life of the converter valve, it is necessary to consider the corrosion resistance when selecting the coil that is in contact with the coolant. Therefore, for the selection of coil materials, there are the following options: aluminum ...

Abstract

The invention provides a mechanical performance design method of a saturated reactor for a converter valve. The mechanical performance design of the saturated reactor needs to consider the following aspects: material selection, electrodynamic analysis, integral structure, suspension installation and supporting, connecting links and appearance, fireproof design, anti-seismic design and the like. The invention gives out an analytical design method for each aspect, takes the electric performance, the waterway performance and the like thereof into account and finally gathers to finish the final mechanical performance design of the saturated reactor. The invention has comprehensive considered factors and systematized and normalized mechanical performance design method.

Description

technical field [0001] The invention relates to the field of power system device design, in particular to a method for designing mechanical properties of a saturated reactor for a converter valve. Background technique [0002] The saturable reactor for DC power transmission converter valve is one of the important components to protect the thyristor in the converter valve. It consists of an iron core and a winding, and uses the saturation characteristics of the iron core material to obtain the saturation characteristics of the electrical parameters. The mechanical performance design of a saturable reactor is a design process with many constraints and sometimes contradictory, so the design process needs to consider many constraints. [0003] Conventional reactors for AC in the power industry have various structural forms, and their design methods are also available in open literature, but they are not suitable for saturated reactors for converter valves. The reactor for conv...
