DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas insulated switchgear for substation equipment, and more particularly to a gas insulated switchgear for substation equipment having a MOF and its bypass circuit.

[0002]

2. Description of the Related Art FIGS. 6 and 7 show a partial plan view and an elevation view of a MOF and a MOF bypass circuit of a conventional gas-insulated switchgear for substation equipment. In the figure, reference numeral 1 denotes a transaction instrument transformer (MOF), a main circuit bus 3, and a MOF.
The bypass circuit bus 4, the MOF bypass disconnector 5, the MOF disconnecting disconnector 6, and the like constitute a closed circuit. Reference numeral 7 denotes a grounding switch, and reference numeral 8 denotes a main circuit bus support stand.

[0003] In the gas insulated switchgear for substation equipment configured as described above, the MOF1 is installed, and the MOF1 is required to be periodically verified. MOF1
Must be separated from the gas insulated switchgear, but it is not possible to take a power outage due to the recent power demand, so by installing the MOF bypass circuit 4 at the time of MOF1 verification, Has come to be recognized.

Conventionally, as shown in the figure, the MOF 1, the main circuit bus 3, the MOF bypass circuit bus 4, and the MOF bypass disconnector 5 are arranged and configured in substantially the same horizontal plane.

[0005]

As described above, the conventional gas insulated switchgear for substation equipment has a wide installation because the MOF bypass circuit and the main circuit of the MOF are arranged and configured on the same horizontal plane. Since it requires an area and requires a stand for supporting the bus of the MOF bypass circuit, the power receiving and transforming equipment is expensive. Conversely, when the installation area cannot be secured and the MOF bypass circuit cannot be provided, there is a problem that it is necessary to take a power outage of the entire equipment at the time of MOF verification.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has been provided with a gas for a substation facility which is arranged and configured so that an MOF can be tested without interruption even in a limited installation area. It is intended to obtain an insulated switchgear.

[0007]

According to the present invention, there is provided a gas insulated switchgear for substation equipment according to the present invention, comprising: a MOF and a main circuit bus;
The MOF bypass circuit bus and the MOF bypass disconnector are arranged in substantially the same vertical plane.

[0008]

In the present invention, since the closed circuit including the MOF is in the vertical plane, the installation area of the substation equipment can be reduced, and the number of mounts for supporting the main bus is reduced.

[0009]

1 to 3 show one embodiment of the present invention. In FIG. 1, a transaction instrument transformer (MOF) 1 is supported by a MOF support base 2. MO with conventional technology
The F bypass circuit bus 4 is branched from the main circuit bus 3 in the horizontal direction (planar) and connected to the MOF bypass disconnector 5, but in this embodiment, the MOF bypass circuit bus 4 is By branching downward from the main circuit bus 3 having a connection port for branching into an insulating bus, and passing through the MOF support base 2, the MOF bypass disconnector 5
And the MOF bypass disconnector 5 is arranged and configured on the same vertical plane with respect to the MOF 1 and the main circuit bus 3. Further, in the prior art, a stand for supporting the main circuit bus 3 was required, but in this embodiment, the MO of the vertical portion is required.
An upper horizontal main circuit bus 3 is supported by an F bypass bus 4 and is fixed to the ground side by a tank located at a right angle. Reference numeral 6 denotes a MOF disconnecting disconnector, and reference numeral 7 denotes a ground switch.

As described above, the MOF 1, the main circuit bus 3,
MOF bypass circuit bus and MOF bypass disconnector 5
However, since they are arranged in substantially the same vertical plane, the installation area can be reduced, and the number of mounts can be reduced.

In the above embodiment, M
Although the OF bypass disconnector 5 is disposed, the MOF bypass disconnector 5 may be provided on the left side of the MOF 1.

In the above embodiment, the main circuit bus 3 is connected to the MO
Although placed above the F bypass circuit bus 4, FIGS.
, The main circuit bus 3 may be arranged on the lower side, and the MOF bypass circuit 4 may be arranged above the MOF 1.

Further, in the above-described embodiment, the case where the disconnecting switch is arranged for the MOF bypass has been described. However, this is not limited to the disconnecting switch but may be another switching device, and the same effects as in the above-described embodiment can be obtained. .

[0014]

As described above, according to the present invention, the MO
F, main circuit bus, MOF bypass circuit bus and M
Since the OF bypass disconnector is arranged and configured on the same vertical plane, the installation area of the power receiving and transforming equipment can be reduced, and the number of busbar supports can be reduced. There is an effect that it is not necessary.
