A box 8c is installed and extends from the main switchboard 4 to the unit distribution area. The bus duct 10 is called a 'breaker box' or a 'reducer box' to protect the track. A power junction box is installed.

The power distribution facilities of these building facilities will be described in more detail with reference to FIG. 2.

As shown in FIG. 2, the cable 6 or the bus duct 10 extends from the main switchboard 4 of the electrical chamber 2 (FIG. 1 needle), and the bus duct branches from the unit distribution area.

In this case, the bus duct 10 between the main switchboard 4 and the unit distribution area is provided with a power junction box 8a called a breaker box, which has a breaker function for line protection purposes, or is reduced from high capacity to small capacity. In the position, a junction box 8b called a reducer box having a breaker function for line protection purposes is provided. Further, at the connection portion between the cable 6 and the bus duct in the unit distribution area, a junction box 8c called a feed in box for connecting the cable and the bus duct or for drawing out power is provided.

As an example of the junction box described above with reference to FIG. 3, the structure of the junction box 30 referred to as the plug hole box described above will be described.

As shown in FIG. 3, the bus duct 10 has a structure in which a plurality of bus bars 14 pass through the inside of the enclosure 12. For power drawing, a drawer 20 is installed at one side of the enclosure 12 of the bus duct 10, and the connection plug 22 drawn from the inner bus bar 14 is installed at the drawer 20. It is.

(Distribution facility)

24 to 26 are views showing a power distribution facility according to the present invention.

As shown in FIG. 24, the above-described power junction boxes, that is, communication and monitoring modules of all power junction boxes regardless of upper and lower loads, are connected to the upper monitoring system 800 through a communication line and a power line. Under the control of the upper monitoring system 800, data is received from each detector and the received data is transmitted.

As already described above, the communication and monitoring module may collect analog data collected by the current detector 411, the voltage detector 412, the leakage current detector 415, and the like by the breaker state detector 413 and the temperature sensor 414. The digital data is processed and reported to the upper monitoring system, and output to the display 320 or display lamp 330 provided in the power junction box.

Therefore, the individual load with the upper monitoring system 800 can be integrated monitoring and management of the lower load through a 1: 1 exchange of information, and the information can also be easily displayed on the site by displaying information on the power junction box itself. .

In addition, when the batch transmission method of data and commands and the time difference transmission method of detection and reporting are used together, total management of subordinate loads becomes more effective and quick.

For example, the monitoring and monitoring module 200 of each power connection box communicates with the upper monitoring system 800 through a communication line to monitor the data for power monitoring including current and voltage information collected by the upper monitoring system. When reporting to 800, high-speed communication is attained by simultaneously receiving transmission requests from the higher-level monitoring system 800 at the same time and transmitting data to the higher-level monitoring system 800 at the transmission timing assigned thereto.

That is, the higher-level monitoring system 800 requests each communication and monitoring module 200 to simultaneously transmit information simultaneously, and receives the information from each communication and monitoring module 200 in order and receives them in order. Communicate For example, the upper monitoring system 800 collectively requests the information transmission at the same time to all the communication and monitoring module 200, and receives data sequentially from each communication and monitoring module 200.

As described above, the upper monitoring system 800 collectively requests the information transmission in the entire communication and monitoring module 200 at the same time, and then receives data from each communication and monitoring module 200 in order to receive the data. The communication and monitoring module 200 does not need to request information transmission individually, so that communication can be performed at a higher speed than in the related art.

25 and 26, the installation configuration for the communication line and the power line for connecting the above-described upper monitoring system 800 and the communication and monitoring module 200 of the individual load is shown.

In the present invention, the communication line and the power line are integrated to facilitate wiring along the bus duct.

To this end, a communication line and a power line for connecting to a plurality of communication and monitoring modules are composed of a unified cable 900. That is, the unified cable 900 according to the present invention is formed by covering a communication cable for use as a communication line and a power cable for use as a power line, and then covering the outside at once with an outer sheath.

The unified cable 900 in which the communication cable and the power cable are integrated in this way is wired along the bus duct 10. As shown in FIGS. 25 and 26, an enclosure of the bus duct 10, specifically, an enclosure In the distribution plate 12 of the insertion slot 12a is formed to extend along the longitudinal direction of the duct, and the unified cable 900 is inserted into the slot 12a, so that the communication line and the power line are connected to the main bus duct. And the bus duct passing through the unit distribution area are integrated and wired.

Since the slot 12a is formed in the enclosure of the bus duct 10, as shown in the cross-sectional view of FIG. 26, the bus duct 10 can be easily removed only by the step of inserting the unified cable 900 into the slot 12a. Can be wired accordingly.

In addition, when the integrated cable 900 is inserted into and installed in the slot 12a of the bus duct, a fixing cap 12b is further added to the slot 12a to more firmly hold the integrated cable 900 at a predetermined distance. It may be provided. As shown in FIG. 26, the fixing cap 12b can be easily and firmly coupled to the groove formed in the slot 12a.

As described above, in the present invention, the communication line and the power line connected to each communication and monitoring module are integrated into a single cable 900, and the single cable 900 is inserted into the slot 12a provided in the enclosure of the bus duct. By inserting wiring, wiring can be performed in one operation of installing the unified cable 900 without separately installing the communication line and the power supply line, so that the wiring work efficiency can be improved.
