Description

Description: TECHNICAL FIELD The present invention relates to an oil-filled electric device facility formed by connecting a plurality of oil-filled electric devices.

(Prior Art) Generally, in this type of equipment, in order to avoid exposing the charging part as much as possible, oil-filled electric devices are connected by an oil pipeline, and electrical connection is made in this oil pipeline. On the other hand, when performing electrical drawing of this kind of equipment using air bushing,
Since the charging portion of this air bushing is exposed, it is necessary to provide it in consideration of the air insulation distance with the oil amount adjusting device (hereinafter referred to as FT) mounted on the upper part of the oil-filled electric device.

FIGS. 3 and 4 show the structure of a conventional facility of this type in which two capacitors and a reactor are connected. 1,
2 is a capacitor, and capacitor elements 1a and 2a, respectively
And FT1E, 2E, and the discharge coil chambers 1d, 2d containing the discharge coils 1c, 2c. Reference numeral 3 is a reactor formed by a reactor container 3b accommodating the reactor coil 3a and FT3E, and one unit forms three phases. Reference numerals 4a and 4b denote oil pipelines, which are attached to the side walls of the discharge coil chambers 1d and 2d and the reactor container 3b so as to electrically connect the capacitors 1 and 2 and between the capacitors 2 and the reactor 3 inside. . Reference numeral 5 denotes an air bushing for electrically drawing in from a transmission system (not shown) or the like, and the oil pipeline 4a
A bushing pocket 6 is provided and installed on the side wall of the discharge coil chamber 1d on the opposite side to which is attached.

(Problems to be Solved by the Invention) However, in the above-mentioned configuration, since the bushing pocket 6 for installing the air bushing 5 is required, the equipment is expensive, and as shown in the figure, the air bushing 5 is used. In order to obtain a sufficient air insulation distance 1 between the terminal 5 '(charging part) and the FT1E mounted on the upper part of the capacitor 1, the bushing pocket 6 and the air bushing 5 should be protruded beyond the side wall of the capacitor container 1b. As a result, the area occupied by this type of equipment is increased and the seismic resistance of the portion is impaired.

(Means for Solving Problems) In view of the above-mentioned points, the present invention provides an air bushing on the upper part of the oil-filled electric device on the pull-in side among a plurality of oil-filled electric devices, and other oil-filled electric devices. At least the oil-filled electric device and the FT for the oil-filled electric device on the pull-in side are mounted on the upper part of the electric device.

(Operation) According to the above configuration, since the air bushing is provided above the pull-in side oil-filled electrical device and the FT is mounted on the other oil-filled electrical device, the charging part of the air bushing and the FT are installed. In addition to the sufficient air insulation distance between and, the air bushing and the like will not protrude from the side wall of the oil-filled electrical device.

(Embodiment) An embodiment of the present invention is shown in FIG. 1 and FIG. In the drawings, the parts denoted by the same reference numerals as in FIGS. 3 and 4 indicate the same or corresponding parts. In the figure, the difference from the configurations of FIGS. 3 and 4 is that an air bushing 5 is provided above the lead-in side condenser 1, and condensers 1 and 2, reactor 3 and oil line 4a are provided above the other condensers 2. FT1 for 4b
This is the point that all 0s are installed together. The FT 10 and the capacitor containers 1b and 2b, the discharge coil chambers 1d and 2d, the reactor container 3b, and the oil pipelines 4a and 4b are communicated by respective oil conduits (not shown). Therefore, according to this configuration, since the air bushing 5 and the FT10 are arranged above the separate capacitors 1 and 2, the air insulation between the terminal 5 '(charging part) of the air bushing 5 and the FT10 is performed. In addition to being able to take the distance 1 sufficiently, the air bushing 5 does not protrude from the side wall of the condenser container 1b, so that the area occupied by this kind of equipment will not increase and the seismic resistance of this portion will also improve. In the above embodiment, an example in which two capacitors are used has been shown, but it goes without saying that three or more capacitors may be used. In this case, the FT is collectively mounted on the other capacitors. It may be installed separately. Furthermore,
The capacitors 1 and 2 may be formed by accommodating the capacitor elements 1a and 2a for three phases in the respective capacitor containers 1b and 2b.

(Effects of the Invention) As described in detail above, according to the present invention, an air bushing is provided on the upper part of the oil-filled electric device on the retracting side, and the FT is extremely simple when mounted on the other oil-filled electric device. In the configuration,
As it does not use a bushing pocket as in the past, it will be cheaper, and in order to obtain the air insulation distance between the live part of the air bushing and the FT, the area occupied by this type of oil-filled electrical equipment will increase. There is an effect such as disappearing.
