Description

plug-in box

technical field

The utility model relates to a power supply bus shunt plug-in device, in particular to a plug-in box.

Background technique

Plug-in boxes are widely used in electric power applications. Plug-in boxes use the method of plugging to tap the electric energy on the busbar to the branch lines, and then transport it to various industrial applications. The main function of the busbar is to collect, distribute and transmit electrical energy, and it is very convenient to use the plug-in box to tap. Therefore, the plug-in box is the key part of the branch current protection, and the performance of the plug-in box directly affects the wiring quality. Industrial connectors are power supply interfaces for various industrial applications. In the prior art, industrial connectors are directly connected to the box of the plug-in box. Because of the limited size of the box, the number of industrial connectors is limited. The connection box has only 3 outlet ports, which are connected to 3 industrial connectors. Such a plug-in box is not compact enough in structure and inefficient in use.

SUMMARY OF THE INVENTION

Purpose of the invention: The technical problem to be solved by this utility model is to provide a plug-in box, the outlet of the plug-in box is connected with the industrial connector outside the box, and more than 3 outlet ports can be set, which solves the problem of the existing plug-in connection. The box structure is not compact and the use efficiency is not high.

Technical scheme: The plug-in box of the utility model includes a box body installed on the busbar, a wire outlet and an industrial connector connected with the wire outlet. Connectors are connected outside the box.

Specifically, the plug-in box has six outlet ports. Six miniature circuit breakers are arranged in the box, the A-phase lines in the busbar are respectively connected to the first outlet and the fourth outlet through two different miniature circuit breakers, and the B-phase wires in the busbar are respectively It is connected to the second outlet and the fifth outlet through two different miniature circuit breakers, and the C-phase line in the busbar is respectively connected to the third outlet and the sixth outlet through two different miniature circuit breakers.

In order to monitor the voltage, current and other parameters of the management line, a monitoring module unit is also arranged in the plug-in box, and the monitoring module unit is connected to the busway communication main line through a communication interface. In a specific application, the monitoring module unit can be two MX-DC-C01 chips, and the communication interface is a DB9 communication interface.

In order to improve the sealing performance and further waterproof and dustproof, the cable fastening device is a sealed casing made of waterproof material.

Beneficial effects: The utility model can provide a plug-in box with 6 outlet ports, equipped with 6 outlet circuits, can supply power to 6 common cabinets at the same time, the circuit structure is compact, the use efficiency can be improved, and the cost performance is relatively high.

Detailed ways

As shown in Figure 1, the plug-in box includes a busbar 1, a box body 2 installed on the busbar, and 6 outlet ports 3. The 6 outlet ports 3 are called the first outlet to the sixth outlet from left to right. Each outlet is led out through the cable fastening device 4 , and the industrial connector 5 is connected to the outlet from the outlet 3 outside the box 2 . The plug-in box is equipped with 6 outgoing circuits and 6 miniature circuit breakers 6 at the same time, and each outgoing circuit is protected by a miniature circuit breaker. The line connection method is that the neutral line 11 and the ground line 12 are connected to 6 outlets after being drawn from the bus bar, and the A-phase line 15 is connected to the first outlet and the fourth outlet through 2 different miniature circuit breakers after being drawn from the bus bar. The B-phase line 14 is connected to the second outlet and the fifth outlet through 2 different miniature circuit breakers after being drawn from the busbar, and the C-phase wire 13 is respectively connected to the second outlet and the fifth outlet through 2 different miniature circuit breakers after being pulled out from the busbar. The third outlet and the sixth outlet, each outlet is provided with a cable fastening device, which can supply power to 6 common cabinets at the same time, with high cost performance. In order to improve the sealing performance and further waterproof and dustproof, the cable fastening device is a sealed housing made of waterproof material. In order to monitor the voltage, current and other parameters of the management line, two monitoring module units 7 are arranged in the box 2, and each monitoring module unit 7 adopts one MX-DC-C01 chip, which is connected to the bus bar 1 through the DB9 communication interface 8 respectively. The communication main line is connected to meet the communication requirements of 6 circuits. As shown in Figure 2, the outlet circuit of the plug-in box leads out the wires through the cable fastening device, and the industrial connector is externally connected to the outside of the plug-in box, which makes the structure of the plug-in box compact. Wiring is not affected.
