An embodiment of the invention provides an electrical switching control method, an electrical switching control device and an electrical switching control box, and please refer to fig. 1 to 11 together.

The other dc power line is connected to the first actuator 50, and the controller 40 is in signal connection with the remote control device, and can receive a control signal from the remote control device and control the first actuator 50 to operate according to the control signal, so that the first actuator 50 connects or disconnects the dc power line connected thereto to or from one or more first connection terminals 31. 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. In a second connection mode, the negative power supply line is connected to the first actuator 50, and the second connection terminals 32 are connected to the positive power supply line.

In addition, two dc power lines are connected to the controller 40 to supply power to the controller 40. Of course, in order to meet the requirements of different voltage controllers 40, a transformer may be provided between the controller 40 and the two dc power lines.

The signal connection between the controller 40 and the remote control device means that the remote control device and the controller 40 may be connected by wire or wireless to transmit signals. The remote control is set according to the communication capability of the controller 40; for example, the controller 40 may be capable of communicating using the internet of things, and the remote control device may be an internet of things server; the controller 40 is capable of communicating using a 485 communication protocol and the remote control device may be a construction monitoring system FSU of a railway works.

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. 8 as an example, the first wiring assembly 30 has 12 dc terminal pairs, and when the electrical switching control box is used on an iron tower, the upper 4 dc terminal pairs can be set as the dc terminal pairs of a mobile operator, the middle 4 dc terminal pairs can be set as the dc terminal pairs of a unicom operator, and the lower 4 dc terminal pairs can be set as the dc terminal pairs of a telecom operator. When a constructor of a mobile operator needs to install new electric equipment, the constructor of the mobile operator has the permission to open the lock 80 on the outer box body 10, can only connect the electric equipment in the upper 4 direct current wiring terminal pairs, and can only connect the electric equipment on the first wiring terminal 31 and the second wiring terminal 32 which are set in advance in the 4 direct current wiring terminals. 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. Other cast-on users such as the UNICOM operator and the telecom operator use the electric exchange control box in the same operation process as the constructors of the mobile operators.

Further, the first actuator 50 includes a plurality of sets of dc switch assemblies corresponding to the plurality of sets of dc terminal pairs one to one, and one dc switch assembly can control whether the first terminal 31 in one dc terminal pair is energized.

Specifically, the electrically driven dc switch 51 has a normally open type, such as a normally open type contactor, that is, when two control terminals of the electrically driven dc switch 51 are not energized, two main terminals are in an off state; the electrically driven dc switch 51 may also be of a normally closed type, such as a normally closed contactor, i.e. when the two control terminals of the electrically driven dc switch 51 are not energized, the two main terminals are in a connected state. The electrical switching control box can set the corresponding electrically-driven dc switch 51 to be a normally-open type or a normally-closed type according to the requirements of different dc connection terminal pairs.

Because each direct current switch assembly has the first circuit breaker 54, the electric exchange control box can protect the electric equipment connected with the electric exchange control box, and the electric equipment is prevented from being damaged due to overload, short circuit and undervoltage in the using process.

With continued reference to fig. 9, the dc switch assembly further includes a shunt 55, wherein the shunt 55 is disposed on the first bus bar 52 or the second bus bar 53 and electrically connected to the controller 40 to measure the current of the electric device on the corresponding dc terminal pair.

The shunt 55 is connected in series with the electric device, and the current passing through the shunt 55 is the current of the electric device. Set up the module of measuring shunt 55 electric current in the controller 40, controller 40 is connected with the both ends of shunt 55, will flow through the current measurement of shunt 55 and come out, and it is long when voltage and power consumption according to DC power supply again, alright with the power consumption that reachs the consumer, and then make remote control device can come the break-make of control consumer according to the power consumption of every consumer.

With continued reference to fig. 8, the electrical switching control box further includes a second actuator 70 installed in the inner case 20 and electrically connected to the controller 40, and a second junction assembly 60 installed in the outer case 10.

Specifically, there are two ways of connecting the two ac power lines, the second wiring assembly 60 and the second actuator 70. In the first connection, the live wire is connected to the second actuator 70, and the fourth terminals 62 are connected to the neutral wire. 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.

When a constructor needs to install alternating-current electric equipment, the lockset 80 on the outer box body 10 is opened, the alternating-current electric equipment is connected to the corresponding third connecting terminal 61 and the corresponding fourth connecting terminal 62, then 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 second executing mechanism 70 to act, the third connecting terminal 61 corresponding to the newly-connected alternating-current electric equipment is connected with an alternating-current power line, and the newly-connected alternating-current electric equipment can normally work.

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 second execution mechanism 70 to act, and a third wiring terminal 61 corresponding to the newly connected electric equipment is connected with an alternating current power supply line, so that the newly connected alternating current electric equipment can work normally.
