Description

本発明の実施形態は、組立作業を容易とし得る金属閉鎖形スイッチギヤおよびその組立方法に関する。   Embodiments described herein relate generally to a metal closed switchgear that can facilitate assembly work and an assembly method thereof.

一般に、金属閉鎖形スイッチギヤは、箱体内が正面側の遮断器室、背面側のケーブル室や母線室などに仕切られている（例えば、特許文献１参照。）。そして、遮断器室においては、引出形の真空遮断器を搭載した遮断器ユニットが組込まれる（例えば、特許文献２参照。）。   Generally, the metal closed type switchgear is partitioned into a circuit breaker room on the front side, a cable room on the back side, a busbar room, and the like (for example, see Patent Document 1). In the circuit breaker chamber, a circuit breaker unit equipped with a drawer type vacuum circuit breaker is incorporated (for example, see Patent Document 2).

この種の金属閉鎖形スイッチギヤの組立においては、図６に示すように、二段積みの場合、箱体１の中間部と下部の正面側と背面側の幅方向にそれぞれコ字状の上段取付板２ａ、および下段取付板２ｂを固定しておき、引出形遮断器３を搭載するＬ字状の上段遮断器ユニット４ａ、下段遮断器ユニット４ｂを背面側から挿入する。上段遮断器ユニット４ａ、下段遮断器ユニット４ｂは、それぞれ引出形遮断器３が移動する上段床板４ａ１、下段床板４ｂ１と三相分の主回路断路部が固定される上段壁板４ａ２、下段壁板４ｂ２を備えている。   In the assembly of this type of metal closed type switchgear, as shown in FIG. 6, in the case of two-stage stacking, the upper part of the U-shape is formed in the width direction of the middle part, the lower part of the front side and the rear side of the box 1 respectively. The mounting plate 2a and the lower mounting plate 2b are fixed, and the L-shaped upper circuit breaker unit 4a and lower circuit breaker unit 4b on which the drawer type circuit breaker 3 is mounted are inserted from the back side. The upper circuit breaker unit 4a and the lower circuit breaker unit 4b are respectively an upper floor plate 4a1, a lower floor plate 4b1 to which the drawer type circuit breaker 3 moves, and an upper stage wall plate 4a2 and a lower stage wall plate to which a main circuit disconnection portion for three phases is fixed. 4b2.

挿入後、上段遮断器ユニット４ａでは、正面側の上段取付板２ａに上段床板４ａ１を上段ボルト５ａで固定し、下段遮断器ユニット４ｂも正面側の下段取付板２ｂに下段床板４ｂ１を下段ボルト５ｂで固定する。また、引出形遮断器３の正面パネルが目視できる開口部を有する上段保護カバー６ａ、下段保護カバー６ｂも、それぞれ正面側の上段取付板２ａ、下段取付板２ｂに固定する。   After the insertion, in the upper circuit breaker unit 4a, the upper floor plate 4a1 is fixed to the front upper mounting plate 2a with the upper bolt 5a, and the lower circuit breaker unit 4b is also connected to the lower mounting plate 2b on the front side with the lower floor plate 4b1. Secure with. Further, the upper protection cover 6a and the lower protection cover 6b having openings through which the front panel of the drawer-type circuit breaker 3 can be visually observed are also fixed to the upper mounting plate 2a and the lower mounting plate 2b on the front side, respectively.

これにより、箱体１内は、上段遮断器ユニット４ａ、下段遮断器ユニット４ｂを固定することで上段遮断器室１ａ、下段遮断器室１ｂを形成することができ、また、背面側には母線室を含めたケーブル室１ｃを形成することができる。なお、ケーブル室１ｃは、ケーブル接続などの最終の組立作業を伴うエリアのため、作業スペースが確保されている。このため、背面側から収納機器を順次挿入して組立をする手順が採用される。   As a result, the upper breaker chamber 1a and the lower breaker chamber 1b can be formed in the box 1 by fixing the upper breaker unit 4a and the lower breaker unit 4b. The cable chamber 1c including the chamber can be formed. Since the cable chamber 1c is an area that involves final assembly work such as cable connection, a work space is secured. For this reason, the procedure of inserting and assembling the storage devices sequentially from the back side is adopted.

FIG. 1 is a view for explaining an assembling procedure of a metal closed switchgear according to Embodiment 1 of the present invention. In FIG. 1, the same components as those in the prior art are denoted by the same reference numerals.

図１に示すように、二段積みの場合、箱体１の両側の側壁の中間部と下部には、正面側から背面側に延びた奥行き方向にそれぞれＬ字状の一対の上段ガイド１０ａ、下段ガイド１０ｂが固定されている。引出形遮断器３を搭載するＬ状の上段遮断器ユニット４ａ、下段遮断器ユニット４ｂは、引出形遮断器３が移動する上段床板４ａ１、下段床板４ｂ１と三相分の主回路断路部が固定される上段壁板４ａ２、下段壁板４ｂ２を備えている。また、引出形遮断器３の正面側には、正面パネルが目視できる開口部を有する上段保護カバー５ａ、下段保護カバー５ｂが設けられる。   As shown in FIG. 1, in the case of two-stage stacking, a pair of L-shaped upper guides 10a each extending in the depth direction extending from the front side to the back side are provided in the middle and lower portions of the side walls on both sides of the box 1; The lower guide 10b is fixed. The L-shaped upper circuit breaker unit 4a and lower circuit breaker unit 4b on which the drawer type circuit breaker 3 is mounted are fixed at the upper circuit board 4a1 and the lower circuit board 4b1 on which the drawer circuit breaker 3 moves and the main circuit disconnection portion for three phases. The upper stage wall board 4a2 and the lower stage wall board 4b2 are provided. Further, an upper protection cover 5a and a lower protection cover 5b having openings through which the front panel can be seen are provided on the front side of the drawer-type circuit breaker 3.

この組立においては、上段遮断器ユニット４ａ、下段遮断器ユニット４ｂをリフターなどで持ち上げ、正面側からそれぞれの上段ガイド１０ａ、下段ガイド１０ｂに載せ、これに沿って移動させ挿入する。挿入後、上段遮断器ユニット４ａでは、正面側の上段ガイド１０ａに設けたネジ穴に上段床板４ａ１を上段ボルト５ａで固定し、下段遮断器ユニット４ｂも正面側の下段ガイド１０ｂに設けたネジ穴に下段床板４ｂ１を下段ボルト５ｂで固定する。また、引出形遮断器３の正面側には、上段保護カバー６ａ、下段保護カバー６ｂを固定する。   In this assembly, the upper circuit breaker unit 4a and the lower circuit breaker unit 4b are lifted by a lifter or the like, placed on the upper guide 10a and the lower guide 10b, respectively, from the front side, and moved along these to be inserted.
