Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0023] figure 1 It is a diagram showing an example of the circuit configuration of the power converter 1 according to the embodiment of the present invention. Here, the power converter 1 is a device that converts AC power to DC power or converts DC power to AC power. figure 1 The circuit configuration of the power converter 1 is the same as that of a conventional general power converter, but in this embodiment, the power converter 1 is particularly configured to convert large power.

[0024] also, figure 1 The power converter 1c that converts AC power to DC power is called a converter, and the power converter 1i that converts DC power to AC power is called an inverter. Also, a device having both the power converter 1c as a converter and the power converter 1i as an inverter is also sometimes referred to as a power converter. In this embodiment, the power c...

Abstract

The present invention relates to a power converter case and a power converter that does not cause a large size and does not impair mechanical strength and impact resistance to suppress eddy current heating. The main body of the power converter case is constituted by a base frame composed of four beams arranged in a quadrangular shape, a ceiling frame composed of four beams arranged in the same manner and connected in a quadrangular shape, and four pillars that connect the four corners of the base frame to the four corners of the ceiling frame. In the middle of the base frame and the ceiling frame, there is provided a shelf supported by two pillars on the front side and the auxiliary pillars on the rear side. At this time, the shelf of the main circuit copper bar for the AC power main circuit nearby is made of stainless steel. In addition, a beam protruding from the rear side is provided between the pillars, and a main circuit copper bar for the DC power main circuit is arranged in the vicinity thereof, and the beam is made of copper material.

Description

technical field [0001] In particular, the present invention relates to a housing for a power converter suitable for accommodating a large-capacitance power converter, and a power converter housed in the housing for the power converter. Background technique [0002] An example of the structure of the frame for accommodating a closed bus bar is disclosed in patent document 1. Conventionally, in a frame (frame body) for accommodating a closed bus bar, there has been a problem that the frame generates heat due to eddy currents when the bus bar is energized. In Patent Document 1, it is shown that the entire frame is made of a non-magnetic material such as aluminum or stainless steel, or a slit is provided in a direction parallel to the generatrix of the frame and the slit is filled with a non-magnetic material, thereby reducing the Heat generation due to eddy currents. [0003] In addition, Patent Document 2 describes an example in which a high-permeability, high-resistance ele...
