JP 2008-283820 A

  In the high-voltage power receiving equipment as described in Patent Document 1, it is possible to appropriately change the type and the number of elements such as a transformer in accordance with the demand of the consumer. For example, as in the high-voltage power receiving equipment 200 shown in FIG. 7, a structure including one disconnector 201, one high-voltage capacitor 202, two light transformers 203 and 204, and one power transformer 205 is adopted. It is also possible. According to such a high voltage power receiving facility 200, it is possible to supply power to two lamp loads and one power load.

  On the other hand, when the high-voltage power receiving equipment 200 shown in FIG. 7 is provided indoors such as the electric room 210, the high-power power receiving panel is replaced Need to be provided. Therefore, it is necessary to newly secure a space for arranging the high-voltage power receiving board in the electric chamber 210. In such a case, for example, in the high-voltage power receiving facility 200 as shown in FIG. 7, a light transformer having both of these functions is used in place of one light transformer 204 and one power transformer 205. After securing a space for one device, it is conceivable to take measures such as installing a high voltage power receiving board in the space.

  By the way, when installing an electric equipment board such as a lighting transformer board or a high voltage receiving board in the electric room 210, the reference line of the installation position of the electric equipment board should be Since it is necessary to perform a so-called ink drawing operation described on the floor surface or the like in the room 210, a large amount of construction time is required. In addition, when the electrical equipment board is actually installed in the electrical room 210, it is also necessary to check the level of the floor surface in the electrical room 210, and then work to level the electrical equipment board. This is also a factor that causes an increase in construction time.

In addition, such a subject may arise similarly not only when replacing | exchanging the electric equipment panel of a high voltage | pressure receiving apparatus, but when newly installing a high voltage receiving apparatus in an electric room.
This indication is made in view of such a situation, and the object is to provide the installation method of the high voltage receiving equipment which can shorten construction time, and the high voltage receiving equipment.

The high-voltage power receiving equipment for solving the above-mentioned subject matter comprises: an electric equipment panel which houses electric equipment therein; and a channel base which is removably assembled on the bottom surface of the electric equipment panel and fixed to the floor surface.
Moreover, the installation method of the high voltage | pressure receiving apparatus which solves the said subject fixes the step which fixes a channel base on the floor surface of the installation place of a high voltage | pressure receiving apparatus, and attaches an electric equipment panel which accommodates an electric apparatus inside to a channel base And d.

  According to the above configuration and method, after the channel base is fixed to the floor surface, the installation of the electric device board is completed by assembling the electric device board to the channel base. At this time, by installing the channel base in advance, the installation position of the electric equipment panel can be determined, and therefore, the same operation as the ink extraction operation can be performed in advance. Therefore, construction time can be shortened. In addition, by performing an operation of leveling the channel base in advance, when the electric device board is assembled to the channel base, the electric device board can be installed horizontally. Thereby, compared with the case where the work of leveling is performed with the installation of an electric equipment panel, construction time can be shortened.

In the above-mentioned high voltage receiving equipment, the channel base preferably has an insertion hole into which an anchor bolt is inserted.
According to this configuration, the channel base can be securely fixed to the floor surface by the anchor bolt inserted into the insertion hole, and as a result, the electrical equipment panel can be securely fixed. Therefore, construction quality can be improved.

In the high-voltage power receiving equipment described above, it is preferable that the channel base has an outer frame portion formed in a square frame shape, and a projecting portion provided on the inner periphery of the outer frame portion and in which an insertion hole is formed.
According to this configuration, the projection can not be projected from the outer peripheral portion of the outer frame while the projection formed with the insertion hole is provided on the channel base, so the installation space can be reduced.

In the high-voltage power receiving equipment described above, it is desirable that the protruding portions be formed at four corners of the inner periphery of the outer frame portion.
According to this configuration, since the channel base can be fixed to the floor surface more reliably, the construction quality can be further improved.

In the above-described high voltage receiving apparatus, the electrical device board is preferably any one of a high voltage receiving board, a high voltage condenser board, a light transformer board, a power transformer board, and a lighting transformer board.
As in this configuration, when any one of a high voltage receiving board, a high voltage condenser board, a light transformer board, a power transformer board, and a lighted transformer board is used as the electric equipment board, replacement of the high voltage power receiving equipment Since work may occur, it is particularly effective to adopt a configuration capable of shortening the construction time as described above.

  According to the present disclosure, it is possible to provide a high voltage power reception facility capable of shortening a construction time, and a method of installing the high voltage power reception facility.
