As a simple indoor power supply device, in order to supply electricity to a housing complex such as an apartment complex, an iron pipe was installed in a borrowed room of the house, and a transformer, bus bar, etc. were supported on the iron pipe to form an electricity supply device. There is something.

However, with conventional equipment, transformers and other equipment were placed cluttered within the rented room, and the busbar connected to the power cable was supported by iron pipes without being shielded from the outside, resulting in a reduction in the occupied area. There was a limit to the amount of power available, and the workability of arranging the transformer and connecting the busbars on site was poor, and it was also not desirable from a maintenance and safety standpoint. In order to solve these problems, we proposed a simple indoor feeding device. This simple indoor power supply equipment has a power switching unit that houses a high-voltage switchgear in advance and a high-voltage insulated bus bar arranged in advance, and a transformer storage unit that houses a transformer in advance and has a high-voltage insulated bus bar arranged in advance. An electricity supply system is constructed by arranging these units in a rented room based on a predetermined layout.

According to this indoor simple supply device, after the power switch unit and the transformer housing unit are arranged on the floor of a rented room, a high voltage insulated bus bar is connected between each unit.
For this reason, if there is a level difference in the floor surface, a difference in level will occur between the bus bars to be connected, making it difficult to connect the bus bars. Therefore, the workability is poor and there is a possibility that a highly reliable product cannot be obtained.

In other words, in order to perform connection work in a narrow work space at the back between each unit, it is preferable to use a removable type that allows the bus bars to be easily connected to each other.

The present invention has been made in view of the above, and in order to provide high reliability to a removable connection part with excellent workability, the bus conductor is connected to the sleeve at the end of the bus conductor near the compression part of the elastic compression sleeve. A gap is provided in between to generate a suction force, and the elastic compression sleeve is connected with an extra length by a flexible conductor so that the extension of the flexible conductor applies a force in the insertion direction to the elastic compression sleeve. The present invention provides a connection device for a high voltage insulated bus bar in a simple indoor supply device. Here, the elastic compression sleeve is, for example, as shown in Japanese Utility Model Publication No. 46-34041,

Therefore, when the elastic compression sleeve 32a is fitted onto the conductor 12b,
The spring 33 part becomes an elastic compression part, and the conductor 12b
A gap 32b' and a gap 32c are formed at the ends of the gap 32b' and the gap 32c.
The gap 32b' is formed by the presence of the enlarged inner diameter part, but the gap 32c cannot be maintained in a close state even if the end of the conductor 12b is connected deep into the conductor insertion part. This occurs unavoidably.

When a large fault current flows through the connection of this high-voltage insulated bus, the conductor 12b and the elastic compression sleeve 32
As shown in FIG. 4, the contact surfaces of a and 32b are
Since a current flows in a nearly perpendicular direction, a repulsive force is generated between the two and tries to weaken the elastic clamping force, but the elastic compression sleeve 32a in the gap 32b'
Since a current flows in the conductor 32b in parallel with the conductor 12b, an attractive force is generated between the two to compensate for the decrease in the elastic compressive force. At the same time, the flexible conductor 31, which has slackened due to its excess length, is expanded by the electromagnetic force caused by the overcurrent. )give. Due to these forces, the elastic compression sleeves 32a and 32b do not fall off even when an overcurrent occurs, and can maintain a predetermined fitting relationship with the conductor 12b.
