BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil-filled condenser device.

[0002]

2. Description of the Related Art In a capacitor device using an oil-filled capacitor, for oil-to-ground insulation, the oil-filled capacitor is insulated and housed in a grounded metal container, and an insulating gas, insulating oil, etc. are placed in the metal container. May be filled with an insulating medium. In this case, this kind of oil-filled condenser needs an oil amount adjusting function against a temperature difference at the time of energization and at the time of stop, or a change in the surrounding temperature.

[0003] Therefore, when a tank-type oil-filled condenser is used as the oil-filled condenser, an oil amount adjusting device such as a feeding tank and a conservator is attached to the oil-filled condenser, and this is installed in a metal container. Then, a large volume metal container is required.

In order to solve this problem, the present inventor has proposed a configuration in which an oil amount adjusting device is installed outside a metal container, and the oil amount adjusting device and the inside of the oil-filled condenser are communicated with each other by a pipe for oil introduction. Proposed separately. According to this, there is an advantage that it is not necessary to use a metal container having a large volume.

On the other hand, when an oil-filled capacitor is installed inside a metal container, it is necessary to install a connecting conductor on the oil-filled capacitor in order to lead out a conductor drawn out of the capacitor body of the oil-filled capacitor. is there. Therefore, the oil-filled condenser must be provided with a connecting conductor for external derivation in addition to the above-described oil guiding pipe, and the configuration for this is extremely complicated.

[0006]

According to the present invention, an oil-filled capacitor is insulated and stored in a grounded metal container, and the metal container is filled with an insulating medium such as insulating gas or insulating oil.
An object of the present invention is to simplify a configuration for leading out capacitor oil and a configuration for leading out a conductor of an oil-filled capacitor to the outside when configuring a capacitor device by installing an oil amount adjusting device outside a metal container.

[0008]

[Function] The inside of the oil-filled capacitor has a connection hole with a through hole.
The connection between the body and the oil guide pipe communicates with the oil amount adjusting mechanism outside the metal container, and the condenser oil inside the oil-filled condenser is adjusted by the oil amount adjusting mechanism. Thus the oil amount adjusting mechanism eliminates the need to install inside the metal container, divided small metal container for installing the oil amount adjusting mechanism to the outside
It can be made volume .

On the other hand, a lead conductor is connected to the connection body between the connection conductor and the oil guide pipe, and the conductor from the capacitor element inside the oil-filled capacitor is drawn out of the metal container by the lead conductor. That coupling body <br/> connection conductor and the oil guiding pipe is to be shared with the flow of the oil amount adjusting mechanism of the capacitor oil described above, to both the Drawer conductor from the capacitor element.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a grounded metal container, 2 is an oil-filled condenser requiring an oil amount adjusting mechanism, for example, a tank type oil-filled condenser,
It is sealed in the metal container 1 and installed insulated from the metal container 1. For example, it is supported in the metal container 1 by a suitable insulator 3. Insulating gas in the metal container 1,
An insulating medium such as insulating oil is enclosed.

A connection conductor 5 having a through hole 4 at the center is insulated and installed on an upper portion of the oil-filled capacitor 2, for example, on an upper cover thereof. For this purpose, for example, a bushing 6 having a central conductor therein may be fixed, and this central conductor may be used as the connecting conductor 5. Reference numeral 7 denotes a presser fitting for fixing the bushing 6. The connection conductor 5 is connected to a conductor 9 drawn out of the capacitor body 8, and one end of the through hole 4 opens into the oil-filled capacitor 2.

A conductive oil guide pipe 10 is connected to the other end of the connection conductor 5. An insulating spacer 11 is provided on the metal container 1, and an oil guide pipe 10 is connected to a pipe 12 supported by the insulating spacer. The pipe 12 opens into the oil pocket chamber 13. The oil pocket chamber 13 communicates with an oil amount adjusting device 15 via a pipe 14. 16 is a condenser oil. In this embodiment, the oil
By pocket room 13, pipe 14, oil amount adjusting device 15
An oil amount adjusting mechanism is configured.

The condenser oil 1 inside the oil-filled condenser 2
6 increases or decreases, the capacitor oil 16 becomes the connection conductor 5
Through the through hole 4, the oil guide pipe 10, and the pipe 12 to the oil pocket chamber 13 and further into and out of the oil amount adjusting device 15. As a result, the required oil amount is adjusted.

Thus, even when a condenser requiring an oil amount adjusting mechanism is used as the oil-filled condenser 2, the oil amount adjusting device 15 is installed outside the metal container 1, so that the metal container 1 has a large capacity. There is no need to use it.

On the other hand, a lead conductor 17 is connected to the oil guide pipe 10 connected to the connection conductor 5. An insulating spacer 18 is attached to the metal container 1, and a lead conductor 17 is connected to a conductor 19 supported by the insulating spacer 18. The conductor 19 is connected to another external electric device. Therefore, the capacitor body 8 is led out through the conductor 9, the connection conductor 5, the oil guide pipe 10, the lead conductor 17, and the conductor 19.

With this configuration, the oil-filled condenser 2
, Only the connection conductor 5 having the through hole 4 is installed,
This and communicating to the oil amount adjusting device 15 of the oil-filled capacitors 2, can be used also in the derivation of the external conductor from the capacitor body 8, thus oil-filled capacitor 2 configuration for the particular purpose it becomes unnecessary to separately provided to.

As the lead conductor 17, a pipe-shaped one as shown in the figure may be used, and this may be connected to the oil guide pipe 10. In this way, when the amount of the condenser oil 16 in the oil-filled condenser 2 increases or decreases, the extraction conductor 1
7, so that the lead conductor 17 is cooled, which is convenient.

A drain valve 20 is provided in the oil pocket chamber 13.
By collecting the condenser oil in the oil pocket chamber 13, it is possible to analyze the condenser oil and detect its deterioration state and the occurrence of an abnormality inside the oil-filled condenser.
