Embodiment approach

[0059] The specific implementation is as follows:

[0060] The shape and quantity of the substrates 4 are determined according to the external and structural dimensions of the transformer cabinet 1 and the power cabinet 9 and the skeleton beams 13. In the specific embodiment, three substrates 4 are divided, and the substrates 4 are further made of a common insulating material—epoxy cloth board. as attached figure 2 Illustrated in the figure is the case where six power unit modules are cascaded, so that the mounting and fixing points of each substrate can be determined, and the fixing holes can be processed.

[0061] According to the layout of the internal power unit modules of the power cabinet 9, determine the layout plan of the transitional connection copper bars 5 on the substrates 4 of each layer, and process the fixing holes for the transitional connection copper bars 5 on each substrate 4, as shown in the appendix. image 3 As shown, the combination of the transition c...

Abstract

The invention discloses a power device combined cabinet connecting device. The power device combined cabinet connecting device comprises a plurality of base plates arranged between two different cabinet bodies, a plurality of transition connection copper bars arranged on the base plates, penetrating through the base plates and used for transition connection of cables between the two different cabinet bodies, a plurality of first fastening external members, a plurality of fourth fastening external members and a plurality of second fastening external members, wherein the cables are fixed to two ends of each transition connection copper bar through the corresponding fastening external members, the transition connection copper bars are fixed to the base plates through the fourth fastening external members, and the base plate is fixed between the two different cabinet bodies through the second fastening external members. By means of the power device combined cabinet connecting device, the technical problem that cable arrangement between a power unit module and a transformer is complicated, a manufacturing period is long and maintainability is poor can be effectively solved.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a cabinet-connecting device for electrical equipment applied to a cabinet of electrical equipment, in particular to high-voltage and high-power converter equipment. Background technique [0002] With the development of the economy, the demand for energy saving is further increased, which promotes the rapid development of converter technology in the power industry. The application of high-power cascade converter devices has penetrated into all walks of life. As a conventional cabinet-type device at present, the electrical connection between the power unit and the transformer mostly adopts direct cable connection. This brings certain troubles and hidden dangers to the cable production, wiring tooling, testing, transportation, on-site installation, debugging, etc. [0003] There are three kinds of structural schemes widely used at present: the first is to use the overall structu...
