CHANNEL BASE OF LARGE SWITCHBOARD WITH ANTI-VIBRATION TYPE FRAME}

The present invention relates to a channel base of a large switchgear having a seismic frame, wherein the seismic frame is mounted on the channel base of the lower side of the large switchgear case, and the vibration acts in a direction parallel to the ground and in a direction perpendicular to the ground. The present invention relates to a channel base of a large switchgear having a seismic frame to be able to endure the durability of the large switchgear.

The large switchboard generally accommodates operation switches and circuits for controlling various facilities, and is disposed on the ground 500 as shown in FIG. 1, and is coupled to the lower side of the case 1 by a bolt 210. It is necessary to secure a seismic structure that can withstand external vibrations such as earthquakes.

That is, the channel base 200 is composed of a body plate 220 and a support plate 240 coupled to the lower surface of the case 1 and penetrate the case 1 and the body plate 220 to the ground 500. The seismic structure is completed by fixing with the bolt 210.

In the drawing, reference numeral 300 denotes a channel base adjacent to the channel base 200.

However, the channel base 200 has a problem that the channel base 200 is vulnerable to vibrations that repeatedly and strongly act in the direction parallel to the ground 500 as well as in the direction orthogonal to the ground 500.

That is, the channel base 200 is due to the strong vibration acting in the orthogonal and parallel directions with the ground 500 on the body of the bolt 210 which is fixed to the ground 500 together with the case 1 and the body plate 200. Fatigue strength is accumulated, and thus there is a problem of being exposed to a fatal weakness that causes breakage such as breaking of the bolt 210.

An object of the present invention is to provide a channel base of a large switchgear having a seismic frame, characterized in that to improve the durability of the large switchgear to solve the problems as described above.

In order to achieve the above object, the present invention, the body piece is coupled to the case lower surface of the large switchboard, and formed extending downward from both sides along the longitudinal direction of the body piece to face each other and each end is in contact with the ground In the channel base of the large switchboard consisting of a support piece for supporting the case, the bottom body piece is disposed in parallel with the body piece and fixed to the ground, and formed upwardly extending from both sides along the longitudinal direction of the bottom body piece It is characterized in that it withstands vibrations acting in a direction parallel to the ground and in a direction orthogonal to the ground by an earthquake-resistant frame that includes a reinforcing supporter facing each other and engaging with the support in the longitudinal direction of the support. do.

Here, the bottom body piece is preferably further provided with a finishing bolt fixed to the ground through a fixing hole formed through a predetermined interval along the longitudinal direction.

At this time, the reinforcing support piece is mutually welded or screwed with the support piece, or the support piece and the reinforcing support piece are coupled to each other by mutual coupling with the engaging projection of a shape corresponding to the coupling rail formed along the longitudinal direction of the support piece. Of course you can.

According to the present invention having the above-described configuration, the reinforcing support pieces of the seismic frame is coupled to the supporting pieces constituting the channel base of the large switchgear case, respectively, and adopts a structure for fixing the bottom body piece of the earthquake resistant frame to the ground. Since it maintains more robust seismic performance against external vibrations such as earthquakes that occur in parallel with and perpendicular to the direction and has a feature that can improve the durability of a large switchboard.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2 is a conceptual view showing the mounting structure of the channel base of the large switchgear having a seismic frame according to the present invention, as shown, the seismic frame 10 according to the present invention is largely reinforced with the bottom body piece 12 It can be seen that the configuration including the support piece 14.

Here, the channel base 20 is further installed on the lower surface of the case 1 of the large switchboard, and the channel base 20 is coupled to the body piece 22 coupled to the lower surface of the case 1. And a support piece 24 extending downward from both sides along the longitudinal direction of the body piece 22 so as to face each other and each end thereof contacts the ground to support the case 1.

For reference, reference numeral 30 denotes a channel base adjacent to the channel base 20.

At this time, it is preferable that the plurality of bolts 21 are coupled to the case 1 by a plurality of bolts 21 through the body piece 22 along the longitudinal direction.

The bottom body piece 12 according to the present invention is disposed in parallel with the body piece 22 and fixedly mounted on the ground 50, and the reinforcing support piece 14 according to the present invention is the bottom body piece 12. Is formed to extend from the mutually coupled with the support piece 24.

The reinforcing support piece 14 is more specifically formed to extend upwardly from both sides along the longitudinal direction of the bottom body piece 12 to face each other and the support piece 24 along the longitudinal direction of the support piece 24. Each combined.

Accordingly, the seismic frame 10 according to the present invention acts in a direction parallel to the ground 50 and in a direction perpendicular to the ground 50 by the bottom body 12 and the reinforcement support 14. It will form a seismic structure to withstand vibration.

Here, the bottom body piece 12 is preferably further provided with a finishing bolt 13 fixedly coupled to the ground 50 through the fixing hole 11 formed through a predetermined interval along the longitudinal direction.

That is, the finishing bolt 13 is directly fixed to the ground 50 through the bottom body piece 12, the fatigue strength is accumulated by the repetitive vibration compared to the coupling between the existing bolt and the channel base It serves to minimize the exposed portion on the ground (50) easy to break.

On the other hand, the reinforcing support piece 14 according to the present invention may be coupled to each other by the support piece 24 and various embodiments as shown in Figs.

First, the reinforcing support piece 14 of the seismic frame 10 according to the present invention may be welded (W) and the support piece 24 of the channel base 20 as shown in Figure 3, as shown in Figure 4 The reinforcing support piece 14 may be coupled to the support piece 24 by a plurality of fastening bolts 15 that are coupled through a plurality of at regular intervals along the longitudinal direction.

In addition, the reinforcing support piece 14 according to the present invention may adopt a method of sliding coupling with the support piece 24 as shown in FIG.

That is, the reinforcing support piece 14 further includes a coupling protrusion 16 having a shape corresponding to the coupling rail 26 formed along the longitudinal direction of the support piece 24 so that the coupling protrusion 16 is coupled to the coupling protrusion 16. The reinforcing support piece 14 is coupled to the support piece 24 by slidingly coupled to the rail 26.

Therefore, with the coupling of the finishing bolt 13 between the bottom body piece 14 and the ground 50 according to the present invention of the above configuration, in various ways between the reinforcing support piece 14 and the support piece 24 By the coupling, the case of the large switchgear can withstand external vibration such as an earthquake acting along a direction perpendicular to or parallel to the ground 50.
