Description

TECHNICAL FIELD The present application relates to a switchgear fixing member for attaching a plurality of components to a switchgear housing, and a switchgear including the same.

A switchgear, which is one of the power receiving and distributing facilities in buildings and factories, contains a device called a circuit breaker that opens and closes an electrical circuit. Generally, lifters are used to install, remove, and transport components such as drawer-type circuit breakers that are housed inside a switchgear housing. For example, a lifter has been disclosed that includes a loading platform on which a drawer-type circuit breaker can be placed, and an attachment member that is detachably provided on the loading platform and supports a circuit breaker table (see, for example, Patent Document 1). ).

Japanese Patent Application Laid-Open No. 2017-210298

However, in the conventional lifter, the draw-out type circuit breaker and other components such as the circuit breaker table cannot be integrally attached to the housing of the switchgear, which complicates the work. In addition, when storing drawer-type circuit breakers and other components, it is necessary to place them on storage pallets. to remove from the pallet.

The present application has been made to solve the above-mentioned problems, and it is possible to integrally attach a plurality of components of a switchgear to a housing and eliminate the need for a pallet when storing those components. The purpose is to

A fixing member for a switchgear according to the present application is capable of being fixed to a guide rail of a housing of the switchgear, and includes a fixing frame for fixing components of the switchgear, and a fixing frame connected to a lower part of the fixing frame. and a floor provided on the opposite side and having a space into which the supporting member of the carrying device can be inserted.

A fixing member for a switchgear of the present application includes a fixing frame for fixing components of the switchgear, and a floor connected to the lower part of the fixing frame and having a space on the opposite side of the fixing frame. components can be integrally attached to the housing, and a pallet can be dispensed with when storing those components.

Hereinafter, a switchgear fixing member according to an embodiment for carrying out the present application will be described in detail with reference to the drawings. In each figure, the same reference numerals denote the same or corresponding parts.

Embodiment 1.
FIG. 1 is a front view of the fixing member for a switchgear according to Embodiment 1, viewed from the insertion side into the housing of the switchgear when the fixing member is attached to the housing of the switchgear. FIG. 2 is a side view of the fixing member for the switchgear as seen from the side.

In FIG. 1, a switchgear fixing member 1 is composed of a fixing frame 3 for fixing a component 2 of the switchgear and a floor portion 4 connected to the bottom of the fixing frame 3 . The constituent parts 2 of the switchgear include a draw-out type circuit breaker and a busbar. The fixed frame 3 is made of metal and has a rectangular frame shape with plate-like crosspieces. The number of component parts 2 fixed to the fixed frame 3 may be one or plural. The floor portion 4 is made of metal and has a rectangular plate shape, and two of the four sides of the floor portion 4 are bent downward at the ends thereof. A space 6 between the downwardly bent protruding portions 5 is a space for receiving a fork or a bucket of a lifter, which is a transportation device.

FIG. 3 is a side view for explaining a method of attaching components of the switchgear to the housing of the switchgear using the lifter 11 according to the present embodiment. As shown in FIG. 3, the fork 12 of the lifter 11 is inserted into the space below the floor 4 of the switchgear fixing member 1, and the switchgear fixing member 1 is scooped up by the fork 12 to form the switchgear housing. It is attached inside the body 13 .

FIG. 4 is a front view showing a switchgear in which a fixing member for the switchgear is attached to a housing. Moreover, FIG. 5 is a perspective view which shows a switchgear. The switchgear housing 13 includes a framework, side plates, and a top plate. omitted.

As shown in FIGS. 4 and 5, the protrusion 5 of the switchgear fixing member 1 is configured to slide on the guide rail 14 of the housing 13, and the switchgear fixing member 1 protrudes. The portion 5 is slid onto the guide rail 14 and moved to the fixed position.

A through hole 15 for a bolt to pass through is formed in the floor portion 4, and the through hole 15 is used to fasten the guide rail 14 and the floor portion 4 with a bolt. When the through hole 15 is displaced from the predetermined position of the guide rail 14, the switchgear fixing member 1 is slid to move to the predetermined position.

The switchgear fixing member configured in this way can fix a plurality of components inside the fixing frame. Multiple components can be integrally attached to the housing.

In addition, since the forks or buckets of a lifter, which is a transportation device, can be accommodated in the spaces between the plurality of protrusions formed below the floor, the lifter can be used to move the space, and the floor can be stored when stored. can play the role of a pallet, so a pallet can be made unnecessary. In addition, it is possible to store a plurality of components fixed inside the fixed frame.

In the present embodiment, a rectangular frame made of metal is used as the fixing frame, but any material and shape may be used as long as the components of the switchgear can be fixed.

Also, although a rectangular plate made of metal is used as the floor, any material and shape may be used as long as it can support the fixed frame. Furthermore, the portions where the ends of the two opposite sides of the four sides of the rectangular floor are bent downward are used as the protruding portions, but the space for the forks and buckets of the lifter, which is a transportation device, can be accommodated in the floor. Another configuration may be used as long as it can be formed under the .

In addition, since the floor is used instead of the pallet, the protruding part is required to support the weight of the switch gear components fixed to the switch gear fixing member, and not to move easily during storage. Therefore, sufficient strength and installation stability are required.

Embodiment 2.
FIG. 6 is a side view showing a fixing member for a switchgear according to Embodiment 2. FIG. The switchgear fixing member of the present embodiment is obtained by adding a sling to the switchgear fixing member of the first embodiment.

In FIG. 6, hangers 21 are attached to the vicinity of the four corners of the floor portion 4 of the switchgear fixing member 1 having the same configuration as in the first embodiment. The hoisting tool 21 is capable of hoisting the switchgear fixing member 1 with a hook or the like, and is formed with, for example, a through hole 22 .

The switchgear fixing member configured in this manner can fix a plurality of components inside the fixing frame, as in the first embodiment. A plurality of components can be integrally attached to the housing by one attachment operation to the body.

In addition, since the forks and buckets of a lifter, which is a transportation device, can be accommodated in the spaces between the plurality of projections formed below the floor, the lifter can be used to move the space, and the floor can be stored during storage. can play the role of a pallet, so a pallet can be made unnecessary.

Furthermore, the switchgear fixing member of the present embodiment can be lifted by a crane or the like using a lifting tool even in a narrow storage space without a lifter work space. It can be used to carry fixing members for the switchgear.

Also, when installing the switchgear fixing member at the bottom of the switchgear housing, if the space at the bottom of the switchgear housing is too narrow for the lifter fork to fit in, use a lifting tool to suspend the switchgear. The fixing member for the switchgear can be moved to a proper position in the lowered state.

Although this application describes various exemplary embodiments, the various features, aspects, and functions described in one or more embodiments are limited to the application of particular embodiments. can be applied to the embodiments alone or in various combinations.
Therefore, countless variations not illustrated are envisioned within the scope of the technology disclosed in the present application. For example, modification, addition or omission of at least one component, extraction of at least one component, and combination with components of other embodiments shall be included.
