3a are formed. Reference numeral 14 denotes a socket wrench. The socket wrench 14 is rotatably provided inside the main body 11 so as to face one end opening. The socket wrench 14 is combined with the blind plug 3 of the connector provided on the cable 1 and rotates the plug in the opening and closing directions. Reference numeral 15 denotes a connecting rod.
1, one end of which is inserted into a hole 14a formed in the head of the socket wrench 14 and
And the other end protrudes outside through a hole 17 formed in the other end of the main body 11. Also,
The connecting rod 15 is prevented from coming out of the hole 17 by the stopper 18. Reference numeral 19 denotes a connection port. The connection port 19 is screwed and fixed to a plurality of holes 20 formed in a peripheral wall of the main body 11 near the other end of the main body structure 12. The connection opening 19 is connected to the socket wrench 14, the connecting rod 15 and the main body structure 12 inside the main body structure 12.
Communicates with the space b surrounded by. An oil collecting pipe 21 is connected to the connection port 19. A pipe socket 21 a is attached to an end of the oil collecting pipe 21, and this pipe socket 21 a is adapted to be screwed into the connection port 19. That is, the oil sampling pipe 21 is connected to the connection port 19 via the pipe socket 21a. Oil collecting pipe 2
The other end of 1 is connected to an unillustrated oil collecting container. The socket wrench 14 and the main body structure 1
The space part c sandwiched between 3 communicates with the space part b and one end opening of the main body structure 3. Thereby, the space portion b and the space portion c
This forms a space a communicating with the opening of the main body structure 3 and the connection port 19. In the figure, reference numeral 22 denotes an O-ring interposed between the main body structure 12 and the main body structure 13, and reference numeral 23 denotes a hole provided in the hole 17 of the main body structure 2 and connects between the hole 17 and the connecting rod 15. This is an O-ring to be sealed. A description will be given of a case in which the insulating oil extractor thus configured is used. When collecting the insulating oil sealed in the cable 1, the protective cap 4 screwed to the connector body 2 is used.
To remove it from the connector body 2. Next, one end opening of the main body structure 13 of the main body 11 is put on the connector main body 2 and the blind plug 3, and the screw portion 13 a of the main body structure 13 is screwed into the screw portion 2 a of the connector main body 2. Thereby, the main body 11 surrounds the periphery of the connector main body 2 and the blind plug 3. At this time, at the same time, the socket wrench 14 is fitted into the blind plug 3 of the connector body 2 and combined therewith. The oil collecting pipe 21 is connected to one or more connection ports 19 in advance, or
Is connected to the connection port 19 at the stage of being screwed into the connector body 2. Next, a suitable tool (not shown) is combined with the tip of the connecting rod 15, and the connecting rod 15 is rotated in the connector opening direction by this tool. With the rotation of the connecting rod 15, the socket wrench 14 rotates in the same direction, and the socket wrench 14 further rotates the blind plug 3 in the opening direction. This makes blind plug 3
Is separated from the valve seat of the connector body 2 and the connector body 2 is opened. Then, the insulating oil sealed in the cable 1 flows out of the connector body 2 through the space between the valve seat of the connector body 2 and the blind plug 3 due to the pressure inside the cable 1.
The outflowing insulating oil enters the space b through the space c in the space a from the open end of the body structure 13 of the body 11. The insulating oil that has flowed into the space b flows out of the connection port 19 through the oil collecting pipe 21 to the oil collecting container. The amount of insulating oil flowing into the oil collecting container is, for example, about 700 CC. In this manner, when collecting the insulating oil from the cable 1, only the operation of rotating the blind plug 3 screwed to the connector main body 2 by the socket wrench 14 in the connector 1 in the connector 1 is performed, and the blind plug 3 is removed. To the connector body 2
The insulating oil can be collected from the cable 1 without removing it from the cable 1. When collecting the insulating oil from the cable 1, the main body 11 surrounds the connector main body 2 and the blind plug 3, and the insulating oil flowing out of the connector main body 2 is collected through a space formed inside the main body 11. It can flow into the tube 21. Therefore, when collecting the insulating oil from the cable 1, the insulating oil can be collected without the insulating oil flowing out of the cable 1 unnecessarily. FIG. 3 shows an insulating oil extractor according to another embodiment of the present invention. The insulating oil extractor of this embodiment is the same as that of the above-described embodiment, except that the connection port 19 is provided with a check valve 24. The check valve 24 includes a valve body 25 and the valve body 2.
And a compression coil spring 2 for applying a spring force to the valve body 25 in a direction in which the valve seat 26 is closed.
7 are provided. A valve pressing body 28 is provided on a pipe socket 21 a attached to a connection end of the oil collecting pipe 21. The check valve 24 is connected to the connection port 19 by the oil collecting pipe 21.
Is not connected, the valve body 25 is pressed by the compression coil spring 27 and contacts the valve seat 26 to be closed. That is, the connection port 19 is closed. When the insulating oil is collected from the cable 1 using the insulating oil extractor of this embodiment, the main body 11 is screwed into the connector main body 2 without connecting the oil collecting pipe 21 to the connection port 19. Then, the connecting rod 15 is rotated by a tool, and the plug 3 is rotated by the socket wrench 14 in a direction to loosen the blind plug 3 to open the connector body 2. As a result, the insulating oil of the cable 1 flows out of the connector main body 2 and reaches the connection port 19 through the space a in each part of the main body 11. Since the check valve 24 provided in the connection port 19 is closed, the insulating oil fills the inside of the main body 11 without flowing out of the connection port 19 to the outside. Next, the pipe socket 2 provided on the oil collecting pipe 21
1a is screwed into the connection port 19 to connect the connection pipe 21 to the connection port 1
9 Then, the valve pressing body 28 provided in the pipe socket 21a pushes the valve body 25 of the check valve 24 in the valve opening direction against the spring force of the compression coil spring 27 to separate from the valve seat 26 and open the check valve 24. . That is, the connection port 19 is opened. Thereby, the insulating oil flows into the oil collecting pipe 21 from the connection port 19 of the main body 11. In this embodiment, effects similar to those of the above-described embodiment can be obtained. The present invention is not limited to the above-described embodiment, but can be implemented with various modifications. As described above, according to the insulating oil dispenser of the present invention, one end opening portion of the main body surrounds the periphery of the connector of the insulating oil container, and the socket wrench is used as a blind plug of the connector. The socket wrench is rotated in the opening direction by the combination and connection shaft to loosen and open the connector. Then, the insulating oil press-fitted into the insulating oil container flows out of the connector, enters the space formed between the main body and the socket wrench formed inside the main body, and further connects the insulating oil from the space. It can flow through the mouth to the oil collecting pipe to collect the superb oil. Therefore, according to the present invention, it is possible to obtain an insulating oil refining device capable of collecting insulating oil from the insulating oil storage container without unnecessarily flowing out the insulating oil from the insulating oil storage container.
