[Problems to be solved by the device]

Therefore, the above-mentioned fixed connection method of the circuit breaker for wiring is added with the circuit breakers 3 for wiring of various capacities (frame values) in accordance with the expansion of facility equipment, or the capacities are different. It may be changed to the circuit breakers 3, ... At this time, the ends of the branch conductors 2 _R , 2 _S , 2 _T fixedly attached to the circuit breaker 3 are connected to the bus conductors 1 _R , 1 _S ,. Since it is necessary to bolt it to 1 _T , a long blackout is required. However, although there is no problem if the power outage is not so affected, for example, in the case of water supply and sewerage and other public facilities, it often affects a large number of customers, and a power outage for a long time becomes a problem.

Further, the height differs depending on the power distribution device, and even the same circuit breaker has different outer shapes and height shapes according to the capacitance values thereof, so that the operation unit is particularly exposed on the panel surface. Since the heights of various devices are different, it is necessary to adjust the height while taking various measures, and there is also a problem in terms of operability.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a power distribution device connecting device that can be connected to a bus bar conductor by work without interruption during the expansion of various power distribution devices.

Another object of the present invention is to provide a power distribution device connecting device which realizes uniform mounting height of these power distribution devices when fixedly mounting various power distribution devices.

[0012] Incidentally, the interval between the electrically conductive connecting portions of each connecting unit is formed so as to become narrower as it is positioned higher, and the power distribution device may be a plurality of devices that are the same or different. .

[0011]

[Action]

 Therefore, in the device corresponding to claim 1, by taking the above-mentioned means, the electrical connection can be made only by inserting the connection terminal of the power distribution device into the device connection hole formed in each phase bus conductor. Therefore, it is no longer necessary to bolt the branch conductors derived from the distribution equipment to the busbar conductors after a power outage during the expansion of the distribution equipment as in the past, and it is possible to avoid the effects of a power failure.

Next, the invention corresponding to claim 2 is to successively stack the connecting units while keeping the electrical connecting connection in the device connecting hole of the busbar conductor, and then to connect the electrically connecting connection of the uppermost connecting unit. Since the connection terminal of the power distribution device is inserted in the part, the operation part of the power distribution device can be set at the same height by adjusting the number of stacking connection units according to the height of the power distribution device.

Device connection parts (device connection hole parts) 13 which are fixedly or integrally formed, and are blind fitting holes of a predetermined depth on the front side of these bus bar conductors 12 _R , 12 _S , and 12 _T with a predetermined interval. … Is formed.

[0015] Then, between these bus conductor 12 _R -12 _S, 12 _S -12 Between _T each line insulating material 14, 14 is interposed, further, these bus conductor 12 _R, 12 _S, 12 _T and line Insulating supports 15 and 15 are provided at both ends of the block in which the inter-insulation materials 14 and 14 are integrated so as to project outward from the busbar conductors 12 _R , 12 _S , and 12 _T.

The busbar conductors 12 _R , 12 _S , and 12 _T are connected to each other by a plurality of device coupling portions 13, ..., As shown in FIG. With respect to the low-voltage three-phase bus system having the above structure, the busbar conductors 12 _R , 12 _S , and 12 _T are connected to each other while being fitted between the insulating supports 15 and 15 as shown in FIG. A connection unit 16 having an electrically conductive connection part is attached to the connection parts 13 ..., Further, the connection terminals of the wiring breaker 17, ... Are inserted and fixed to the upper electrically conductive connection part of the connection unit 16 ,. If necessary, the wiring breaker 17 is fixed to the connection unit 16 by screwing it from the outside. Reference numeral 18 is a secondary side wiring.

The wiring breakers 17, ... Are connected to the device connecting portions 13, .. of the busbar conductors 12 _R , 12 _S , 12 _T via the connecting unit 16, but the connecting unit 16 It is also possible to insert the circuit breakers 17, ...
