Locks 80 are provided on both the inner case 20 and the outer case 10, and the opening authority of the lock 80 provided on the inner case 20 is configured to be higher than the authority of the constructor, and the opening authority of the lock 80 provided on the outer case 10 is configured to be able to be acquired by the constructor.

Specifically, there are two ways of connecting the two dc power lines, the first wiring assembly 30 and the first actuator 50. In the first connection mode, the positive power line is connected to the first actuator 50, and the second terminals 32 are both connected to the negative power line.

If the constructor opens the outer box body 10, the misconnection occurs, and the electric equipment is not connected to the corresponding first connecting terminal 31 and the second connecting terminal 32; the remote control device sends an electrified control signal to the controller 40, and the controller 40 controls the first executing mechanism 50 to act, so that the first connecting terminal 31 correctly corresponding to the newly connected electric equipment is connected with the direct-current power supply line; however, since the constructor makes a misconnection, the electric equipment cannot be used normally, so the constructor can only correct the misconnection and connect the electric equipment to the corresponding first connecting terminal 31 and the second connecting terminal 32.

Taking fig. 1 as an example, the first wiring assembly 30 has 12 dc wiring terminal pairs, and when the intelligent distribution box is used on an iron tower, the upper 4 dc wiring terminal pairs can be set as the dc wiring terminal pairs of a mobile operator, the middle 4 dc wiring terminal pairs can be set as the dc wiring terminal pairs of a unicom operator, and the lower 4 dc wiring terminal pairs can be set as the dc wiring terminal pairs of a telecom operator.

After the mobile operator connects the electric equipment, the constructor uses the operation and maintenance terminal to send a power-on application signal to the remote control device, the remote control device receives the power-on application signal and then transfers the power-on application signal to an approval terminal held by an approver for approval, the approver uses the approval terminal to approve the power-on application signal, the approval terminal sends the approval signal to the remote control device, the remote control device sends a power-on control signal to the controller 40, the controller 40 controls the first executing mechanism 50 to act, and the first connecting terminal 31 corresponding to the newly connected electric equipment is connected with the direct current power line, so that the newly connected electric equipment can work normally.

This intelligent power distribution box can set up corresponding electrically-driven direct current switch 51 for normally open type or normally closed type according to the demand that different direct current binding post were right.

In a second connection, the neutral wire is connected to the second actuator 70, and the fourth terminals 62 are connected to the live wire.
