Abstract

<P>PROBLEM TO BE SOLVED: To provide a reactor mounting device allowing a reactor to have a big capacity and securing a cable retracting space while permitting safe transportation. <P>SOLUTION: The reactor mounting device is equipped with a bottom board 5 having a cable retracting port 4 for retracting a cable 2 into a board, an equipment base 6, and an external terminal 3 while the box type bottom plate 5 with opened upper surface is installed horizontally and with two extended vertically parallel sides. Then, the tip ends of the vertical plates are worked so as to be bent perpendicularly toward inside to form a mounting unit of the equipment base 6 to be horizontally attached thereto for mounting the reactor 1. <P>COPYRIGHT: (C)2005,JPO&NCIPI

しかしながら、従来のリアクトル取付け方法は、器具ベースを垂直に取付けて盤後面と器具ベースの間をケーブル引込スペースとして確保している。器具ベースが垂直面のため、重量物を取付ける構造に適さず、小容量のリアクトルしか取付けられないという問題があった。また、盤を輸送する場合は垂直の取付け面からリアクトルの重心が離れてしまうため、振動に弱い構造となっていた。
そこで、本発明はこのような問題点に鑑みてなされたものであり、リアクトルを大容量化するとともにケーブル引込スペースを確保し、安全に輸送することができるリアクトル取付け装置を提供することを目的とする。 However, in the conventional reactor mounting method, the tool base is mounted vertically to ensure a cable lead-in space between the rear panel surface and the tool base. Since the instrument base is a vertical surface, it is not suitable for a structure for attaching heavy objects, and there is a problem that only a small capacity reactor can be attached. Further, when the board is transported, the reactor's center of gravity is separated from the vertical mounting surface, so that the structure is weak against vibration.
Therefore, the present invention has been made in view of such problems, and an object of the present invention is to provide a reactor attachment device that can increase the capacity of the reactor, secure a cable drawing space, and can be transported safely. To do.

また、請求項２に記載の発明は、前記底板と前記器具ベースとの間に空間を設けたものである。 In order to solve the above problem, the present invention is configured as follows.
The invention according to claim 1 is a reactor mounting device for a control center comprising a bottom plate having a cable lead-in port for drawing a cable into the panel, an instrument base, and an external terminal.
The bottom plate is a box-shaped one with an open top surface, and two parallel sides are extended in the vertical direction, and the tip portion is bent inward at right angles to form a mounting portion for mounting the device base. It attaches to the attachment part horizontally.
According to a second aspect of the present invention, a space is provided between the bottom plate and the instrument base.

請求項２に記載の発明によれば、底板と器具ベースとの間に垂直方向の空間を設けたことにより、この空間を利用して、ケーブル引込スペースを確保することができる。さらに、底板の形状を変えることで盤フレームに強固に固定することができる。 According to the first aspect of the present invention, the heavy-weight reactor can be easily accommodated by changing the shape of the bottom plate and the mounting of the instrument base from the vertical direction to the horizontal direction.
According to the second aspect of the present invention, by providing a vertical space between the bottom plate and the instrument base, it is possible to secure a cable lead-in space using this space.
