Description

[Detailed Description of the Invention] The present invention relates to a substation device with a building, in which a special high voltage transformer, a gas insulated switchgear (hereinafter referred to as GIS), etc. are arranged inside the building.

In order to efficiently arrange various devices such as GIS within a building, it is necessary to use the limited space within the building effectively.

In order to maximize the features of substation equipment with a building, the configuration of each device, that is, the layout design, is an important issue.

Examples of conventional substation equipment with buildings are shown in FIGS. 1 to 3.

As shown in the figure, this substation equipment with a building includes a building 1 having walls 1A to 1D, and the room in which the special high voltage transformer 2 of the building 1 is installed is an atrium extending through the adjacent first and second floors. It has a structure.

In this atrium structure room, a plurality of special high voltage transformers 2 are installed along one wall IB, and a GIS 3 is installed along the opposite wall 1D, and both are connected at a connecting part 4. has been done.

In addition, in the figure, 5 is a voltage transformer, 6 is a disconnector, and 7 is a voltage transformer.
is a line arrester installed below it, 8 is a trading transformer, 9 is a grounding switch, 10 is a cable head, 1
1 is an instrument current transformer, 12 is a gas breaker, 13 is a wall IB
A radiator 14 is installed outside the building 1 adjacent to the radiator, and 14 is a loading/unloading entrance formed in the wall IA.

In the case of such substation equipment with a building, it is normal to consider the removal route in case of failure.

However, in the case of the layout shown in FIGS. 1 to 3, the extra high voltage transformer 2 is surrounded by the walls IA, IB, and lc of the building 1, so there is no way to take it out.

Therefore, when carrying out the special high voltage transformer 2, the wall IB will be made of blocks, and the wall IB will be dismantled.

At this time, of course, the heat radiator 13 must also be removed.

For this reason, there was a drawback that it required a lot of effort and cost.

Furthermore, the conventional layout has the disadvantage that the planar space of the building 1 is large.

The present invention proposes a substation device with a building that does not have the above-mentioned drawbacks, and will be described in detail below with reference to embodiments shown in the drawings.

As shown in FIGS. 4 to 6, in the substation equipment with a building of this embodiment, the room in which the special high voltage transformer 2 of the building 1 having walls IA to ID is installed is located on the adjacent first and second floors. The atrium has a structure.

Each special high voltage transformer 2 is placed in the atrium structure room, with a radiator 1
It is installed along wall IB near 3, and the wall ID on the opposite side is
On the side, an ejection path for the transformer 2 is connected to the ejection port 14 of the building 1, as shown by an arrow.

A GIS 3 is installed above the special high voltage transformer 2 along the wall IB, and the special high voltage transformer 2 and the GIS 3 are connected by a connecting portion 4 raised from the top surface of the special high voltage transformer 2.

Note that the connecting portion 4 may be raised from the side of the extra high voltage transformer 2.

Although the layout of this embodiment increases the overall height compared to the conventional layout, the reason why such a layout is effective is as follows.

In general, the floor height of Building 1 is often set at about 3.5 kW, but equipment cannot be stored in special high-pressure equipment rooms of the 66/77 KV class at this floor height.

In this case, for example, if the floor height is set to about 5.5 m, special high voltage equipment can be accommodated, but if the floor height of 5.577 L is not required on floors other than the special high voltage equipment room, wasted space on other floors. Because of this, the floor height is usually around 3.5 m, and only the special high-voltage equipment room has an open ceiling on the first and second floors, and the height of the special high-voltage equipment room is often about 7 m (see Figure 6).

In Figure 6, 15A is the 1st floor and 15B is the 2nd floor.
It is a floor.

Therefore, if the 66/77 KV extra high voltage transformer 2 and the GIS 3 are arranged in a plane in the extra high voltage equipment room, a wasted space will be created in the upper part.

Therefore, in the present invention, the atrium effectively uses the upper space of the structural room and brings out the benefits associated with it.

As explained above, in the substation equipment with a building of the present invention, the room in which the special high-voltage transformer is installed in the building has an atrium structure that extends through the adjacent upper and lower floors; It is installed on the wall side of the room near the radiator, and on the opposite wall side, an egress path for the extra high voltage transformer is connected to the egress entrance of the building, and the gas insulated switchgear is connected to the extra high voltage transformer. According to the present invention, there is no need to demolish the walls of the building when transporting the special high voltage transformer, and the work of transporting the special high voltage transformer can be carried out without much effort and expense. can.

Furthermore, the layout of the present invention allows the planar space of the building to be reduced.

Furthermore, in this invention, the atrium is structured as a room in which the gas-insulated switchgear and special high-voltage transformer are installed above and below, so there is no need to raise the floor height of other rooms, and there is no wasted space in other rooms. In addition, the atrium can effectively utilize the upper space of the structural room.
