Embodiment approach

[0059] Concrete implementation scheme is as follows:

[0060] The shape and quantity of the substrate 4 are determined according to the external structure dimensions of the transformer cabinet 1 and the power cabinet 9 and the skeleton beam 13. In the specific embodiment, three substrates 4 are divided, and the substrate 4 is further made of commonly used insulating material—epoxy cloth board. as attached figure 2 What is shown in the figure is the case of cascading 6 power unit modules, so that the installation 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, the layout scheme of the transition connection copper bars 5 on each layer of substrate 4 is determined, and the fixing holes for the transition connection copper bars 5 are processed for each substrate 4, as shown in the attached image 3 As shown in FIG. 1 , the combination of the t...

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-combining connection device for electrical equipment applied to electrical equipment cabinets, in particular to high-voltage and high-power converter equipment. Background technique [0002] With the development of the economy, the demand for energy saving has further increased, which has promoted the rapid development of the converter technology in the power industry. The application of high-power cascaded 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 is mostly connected by direct cables. This brings certain troubles and potential safety hazards to the whole set of cabinet-type devices in terms of cable production, wiring tooling, testing, transportation, on-site installation, and commissioning. [0003] At present, there are three kinds...
