があった、。Since the conventional power converter mounting device is configured as described above, the mounting method is complicated. Also, because the stones are usually made of ebonite or ceramic, they are weak against stress such as tension and shearing, and there are other problems such as the difficulty of vertically mounting heavy power converters (mounting method in which the mounting plate is vertical). was there,.

A magnetic member is arranged.

以下、この発明の一実施例を図について説明する。 An embodiment of the present invention will be described below with reference to the drawings.

的に絶縁出来る構成にする、。In FIG. 1, the power converter (8) is first attached to a mounting plate in order to fix the power converter (8) to the pedestal (1) while insulating it from high frequencies. Next, fasten with metal or other highly conductive mounting bolts (4a) and washers (4b). Furthermore, by inserting a ferrite ring (4C), which is a magnetic material, around the mounting pole (4a), it is configured to be insulated at high frequencies.

、電力変換装置（３）から流出する高周波ノイズを低減
することができる。Since the power converter (8) performs high frequency switching, it generates high frequency noise. If the power converter (8) is directly attached to the pedestal (1), the stray capacity (7) will become infinite and high frequency noise will flow out of the power converter. Therefore, first fix the power converter (8) to the conductive mounting plate, then reactor (6).
) and then fix it to the ground at a distance from the pedestal (1). As a result, the storage capacity becomes smaller. In addition, the bolt (4a) and the ferrite ring (4c) constitute a one-turn saddle, which allows for low impedance to be grounded for direct current and low frequency alternating current, and conversely, high impedance for high frequency alternating current. As a result, high frequency noise flowing out from the power conversion device (3) can be reduced.
固定強度については、金属製の取付ボルトを使用してい
るため、従来のガイシを使用した固定よりも強くなる。As for the fixing strength, because it uses metal mounting bolts, it is stronger than conventional fixings using insulators.
尚、上記実施例では、直流電源装置の固定法について説

とる。FIG. 3 is a block diagram of the fixing device shown in FIG. 1 with further increased strength. Since the mounting bolt (4a) in FIG. 1 is made of metal, its strength is stronger than that of conventional fixing methods. However, when a power converter is installed vertically, bending stress and shear stress are applied to the ferrite ring. Ferrite is originally a material that is weak against the above stress. Therefore, in order to further strengthen the strength of the above-mentioned stress and protect the ferrite ring, a spacer (8) having high strength against the above-mentioned stress and high insulation properties (for example, engineering plastic such as Teflon or polycarbonate) is placed around the ferrite ring (40). ) is used to reduce bending stress and shear core force, making it less susceptible to IJing.

Although it is fixed in 1 to 3 places, you may use conventional insulated mounting means for the rest.Alternatively, you can use conventional insulated mounting means and separately attach the mounting plate and pedestal to conductive Part 1
For example, the connection may be made using an electric wire or the like, and a magnetic member such as a ferrite ring may be used to wrap the electric wire.

This has the advantage that it can be obtained with a simple structure.
