Description

[Detailed explanation of the idea] 〔Technical field〕 This invention relates to the improvement of capacitor equipment.

[Conventional technology and problems]

FIG. 1 shows a front view of an example of conventionally used capacitor equipment.

2 is a tank that stores the capacitor body;
3 is a tank that houses the series reactor main body, and an upper chamber 8 is integrally formed on the tank 2 side.

Although not shown, a discharge coil or the like may be placed in this upper chamber 8, and a lead wire from the capacitor body is connected to the reactor body of the tank 3 via the lead-in side air bushing 1 and a duct 4, which will be described later. be done. The upper chamber 8 of the tank 2 and the tank 3 are connected by an oil duct 4.
The electrical connection between the capacitor and the reactor is made through the capacitor.

Generally speaking, the insulating oil filled in the capacitor, the oil duct, and the insulating oil filled in the reactor have different properties. The oil amount adjusting devices 5a and 5b are individually placed on the upper surface of the holder. In addition, in the figure, 7 is a pedestal that supports the oil amount adjusting device 5b above.

When the oil amount adjusting device 5a is arranged as shown in the figure, the air bushing 1 on the retraction side has its upper chamber 8.
Although it is difficult to install the bushing on the top surface, in order to maintain the necessary insulation distance A between the inlet side air bushing 1 and the oil amount adjustment device 5a, the bushing is mounted laterally from the upper chamber 8 as shown in the figure. A pocket 6 is made to protrude and an air bushing 1 is attached to it.

Furthermore, since it is difficult to arrange the oil amount adjusting device 5b on the tank 3 side on the same surface at the same time as the oil duct 4, a pedestal 7 is extended to the side and the oil amount adjusting device 5b is placed on it. There is.

However, if the bushing pocket 6 is attached, the number of sealing parts increases accordingly, which reduces oil-tight reliability, complicates the structure, and increases cost accordingly.

Further, in order to hand-hold the oil amount adjusting device 5b, a mount 7 is also required.

[Disclosure of invention]

This invention is a type of capacitor that receives power through air bushings and connects the capacitor and series reactor with an oil duct, in order to avoid the bushings and the messy arrangement of the oil volume adjustment device at the top of the tank of the capacitor equipment as described above. In equipment,
The oil amount adjustment device on the condenser side and the oil amount adjustment device on the series reactor side are installed on the oil duct that connects the condenser side and the series reactor side, and the oil amount adjustment device is installed on the oil duct. It is located in a condenser facility where a lead-in air bushing was installed above the upper chamber of the condenser tank that had disappeared.

The present invention will be explained below with reference to embodiments shown in the drawings. Figure 2 is a top view of the embodiment of the present invention;
The figure is also a front view.

The figure shows a three-phase capacitor installation, and the same parts as in FIG. 1 are designated by the same reference numerals.

An upper chamber 8 is provided integrally with the tank 2 at the upper part of the tank 2 that houses the capacitor body. Further, the tank 3 that houses the reactor body extends laterally from the upper chamber 8 of the tank 2 and is connected to an oil duct 4 that reaches the upper surface of the tank 3 in the vertical direction. On this oil duct 4, an oil amount adjusting device 5' consisting of a plurality of metal bellows, for example, is integrated and arranged in a direction transverse to the oil duct 4,
Fix it. Needless to say, each metal bellows is divided and filled with the same insulating oil as the insulating oil that is filled in the capacitor and the series reactor. 3. Communicates with the oil duct 4.

In addition, a plurality of air bushings 1 on the lead-in side are installed vertically or inclined on the upper surface of the upper chamber 8 of the tank 2, and the capacitor body in the tank 2 is connected to the air bushings 1 on the lead-in side through lead wires. The capacitor body and the series reactor body are connected to each other by arranging a connecting conductor within the oil duct 4. In addition, as shown in FIG. 4, the oil amount adjusting devices on the condenser side and the series reactor side are not integrated, but are separated, and the oil amount adjusting device 5 on the condenser side is placed on the side closer to the condenser tank 2 on the oil duct 4. ″、
The series reactor and the oil amount adjusting device 5 on the oil duct side may be installed on the side closer to the series reactor tank 3.

Further, even in the case of a single phase, by providing a simple frame on the oil duct 4, both oil amount adjusting devices may be installed in an integrated state or in a separated state.

〔effect〕

As explained above, by installing the oil amount adjustment device on the oil duct, a sufficient distance B between the air bushing and the air bushing can be ensured. Therefore, a bushing pocket that projects laterally is provided to separate the air bushing. This also eliminates the need for a stand for the series reactor oil amount adjustment device.

In particular, when the oil amount adjusting devices on the capacitor side and the series reactor side are integrated into a composite structure as shown in FIGS. 2 and 3, the upper part of the capacitor equipment becomes tidy and aesthetically pleasing.
