For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0045] The embodiment of the present invention provides a power switch. Please refer to the accompanying drawings in the specification. Figure 1 To Figure 5.

[0046] like Figure 1 As shown, an embodiment of the present invention provides a power switch, comprising an outer box 10, an inner box 20 and a first wiring assembly 30 installed in the outer box 10, and a controller 40 and a first actuator 50 installed in the inner box 20 and electrically connected to each other. The first wiring assembly 30 includes a plurality of groups of DC terminal pairs having first wiring terminals 31 and second wiring terminals 32, and each first wiring terminal 31 is connected to the first actuator 50, and each second wiring terminal 32 is connected to one of the DC power lines. Another DC power line is connected to the first actuator 50, and the controller 40 is connected to the remote control device signal, can receive the control signal of the remote control device, and control the first actuator 50 to act according to the control signal, so that the first actuator 50 connects or disconnects the DC power line connected to it with one or more first wiring terminals 31. The inner box 20 and the outer box 10 are both provided with locks 80 , and the opening authority of the lock 80 provided on the inner box 20 is configured to be higher than the authority of the construction personnel, and the opening authority of the lock 80 provided on the outer box 10 is configured to be accessible to the construction personnel.

[0047] Specifically, there are two connection modes between the two DC power lines, the first wiring assembly 30 and the first actuator 50. The first connection mode is to connect the positive power line to the first actuator 50, and the second wiring terminals 32 are all connected to the negative power line. The second connection mode is to connect the negative power line to the first actuator 50, and the second wiring terminals 32 are all connected to the positive power line.

[0048] 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 the controller 40 with different voltages, a transformer may also be provided between the controller 40 and the two DC power lines.

[0049] The signal connection between the controller 40 and the remote control device means that the remote control device and the controller 40 can be connected by wire or wirelessly to transmit signals. The remote control device is set according to the communication capability of the controller 40; for example, if the controller 40 can use the Internet of Things communication, the remote control device can be an Internet of Things server; if the controller 40 can use the 485 communication protocol for communication, the remote control device can be a construction monitoring system FSU of the iron building.

[0050] The construction personnel only have the authority to open the lock 80 on the outer box 10, can open the outer box 10, and connect the electrical equipment to the corresponding first terminal 31 and second terminal 32, and then the construction personnel use the operation and maintenance terminal to send a power-on application signal to the remote control device. After receiving the power-on application signal, the remote control device forwards the power-on application signal to the approval terminal held by the approval personnel for approval. After the approval personnel approves the power-on application signal using the approval terminal, the approval terminal sends the approval signal to the remote control device, and the remote control device sends a power-on control signal to the controller 40. The controller 40 controls the first actuator 50 to operate, and connects the first terminal 31 corresponding to the newly connected electrical equipment to the DC power line, so that the newly connected electrical equipment can work normally.

[0051] If the construction personnel open the outer box body 10 and make a wrong connection, and fail to connect the electrical equipment to the corresponding first terminal 31 and the second terminal 32; the remote control device sends a power-on control signal to the controller 40, and the controller 40 controls the first actuator 50 to operate, and connects the first terminal 31 correctly corresponding to the newly connected electrical equipment to the DC power line; and since the construction personnel made a wrong connection, the electrical equipment cannot be used normally at this time, so the construction personnel can only make corrections and connect the electrical equipment to the corresponding first terminal 31 and the second terminal 32.

[0052] by Figure 1For example, the first wiring assembly 30 has 12 DC wiring terminal pairs. When the power switch is used on an iron tower, the upper 4 DC wiring terminal pairs can be set as DC wiring terminal pairs of mobile operators, the middle 4 DC wiring terminal pairs can be set as DC wiring terminal pairs of Unicom operators, and the lower 4 DC wiring terminal pairs can be set as DC wiring terminal pairs of telecom operators. When the construction personnel of the mobile operator need to install new electrical equipment, the construction personnel of the mobile operator have the authority to open the lock 80 on the outer box 10, and can open the lock 80 on the outer box 10, and can only connect the electrical equipment to the upper 4 DC wiring terminal pairs, and can only connect to the first wiring terminal 31 and the second wiring terminal 32 set in advance among the 4 DC wiring terminals. After the mobile operator has connected the power-consuming equipment, the construction personnel use the operation and maintenance terminal to send a power-on application signal to the remote control device. After receiving the power-on application signal, the remote control device forwards the power-on application signal to the approval terminal held by the approval personnel for approval. After the approval personnel use 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 actuator 50 to operate, and connects the first connection terminal 31 corresponding to the newly connected power-consuming equipment to the DC power line, so that the newly connected power-consuming equipment can work normally. When using this power switch, other railway users such as China Unicom operators and telecom operators follow the same operation process as the construction personnel of the above-mentioned mobile operators.

[0053] Furthermore, the first actuator 50 includes a plurality of DC switch components corresponding to the plurality of DC terminal pairs, and a DC switch component can control whether the first terminal 31 in a DC terminal pair is energized. Figure 2 As shown, the DC switch assembly includes an electrically driven DC switch 51, a first busbar 52 and a second busbar 53. One end of the first busbar 52 and one end of the second busbar 53 are respectively connected to two main terminals of the electrically driven DC switch 51, the other end of the first busbar 52 is connected to a DC power line, and the other end of the second busbar 53 is connected to one of the first terminals 31. The controller 40 is connected to the two control terminals of the electrically driven DC switch 51 through wires to control the on and off of the electrically driven DC switch 51.

[0054] like Figure 2 As shown, the electric drive DC switch 51 has four terminals, namely two main terminals and two control terminals. Figure 2Taking the position shown as an example, two main terminals are located on the right side of the electric drive DC switch 51, and the two main terminals are connected to the first busbar 52 and the second busbar 53 respectively; two control terminals are located on the left side of the electric drive DC switch 51, and both control terminals are connected to the controller 40. The controller 40 can send a control signal to the two control terminals of the electric drive DC switch 51 to connect or disconnect the two main terminals of the electric drive DC switch 51. Among them, the electric drive DC switch 51 can be a switch that can be opened and closed by a control current, such as a contactor or a relay.

[0055] Specifically, the electric drive DC switch 51 has a normally open type, such as a normally open contactor, that is, when the two control terminals of the electric drive DC switch 51 are not powered, the two main terminals are in a disconnected state; the electric drive DC switch 51 also has a normally closed type, such as a normally closed contactor, that is, when the two control terminals of the electric drive DC switch 51 are not powered, the two main terminals are in a connected state. The power switch can set the corresponding electric drive DC switch 51 to be a normally open type or a normally closed type according to the requirements of different DC terminal pairs.

[0056] In addition, the first busbar 52 and the second busbar 53 can both be copper bars, or can be made of other conductive materials.

[0057] Reference Figure 2 The DC switch assembly further includes a first circuit breaker 54, and the end of the first busbar 52 away from the electrically driven DC switch 51 and the end of the second busbar 53 away from the electrically driven DC switch 51 are both connected to the first circuit breaker 54. The DC power line is connected to the first busbar 52 through the first circuit breaker 54, wherein a first terminal 31 is connected to the second busbar 53 through the first circuit breaker 54.

[0058] The circuit breaker has overload, short circuit and undervoltage protection functions and has the ability to protect the line and power supply. Since each DC switch assembly has a first circuit breaker 54, the power switch can protect the power equipment connected thereto and prevent the power equipment from being damaged due to overload, short circuit and undervoltage during use.

[0059] Continue to refer to Figure 2 The DC switch assembly further includes a shunt 55, which is disposed on the first busbar 52 or the second busbar 53 and is electrically connected to the controller 40 to measure the current of the electrical equipment on the corresponding DC terminal pair.

[0060] Figure 2In the embodiment, the shunt 55 is arranged on the first busbar 52, and of course, the shunt 55 can also be arranged on the second busbar 53. The shunt 55 and the electric device are in series connection, and the current passing through the shunt 55 is the current of the electric device. A module for measuring the current of the shunt 55 is arranged in the controller 40, and the controller 40 is connected to both ends of the shunt 55 to measure the current flowing through the shunt 55. Then, according to the voltage of the DC power supply and the duration of power consumption, the power consumption of the electric device can be calculated, so that the remote control device can control the on and off of the electric device according to the power consumption of each electric device.

[0061] Continue to refer to Figure 1 The power switch also includes a second actuator 70 installed in the inner box 20 and electrically connected to the controller 40, and a second wiring assembly 60 installed in the outer box 10. The second wiring assembly 60 includes a plurality of AC terminal pairs having a third terminal 61 and a fourth terminal 62, and each third terminal 61 is connected to the second actuator 70, and each fourth terminal 62 is connected to one of the AC power lines. Another AC power line is connected to the second actuator 70, and the controller 40 can control the second actuator 70 to act according to the control signal, so that the second actuator 70 connects or disconnects the AC power line connected thereto with one or more third terminals 61.

[0062] Specifically, there are two connection modes between the two AC power lines, the second wiring assembly 60 and the second actuator 70. The first connection mode is to connect the live wire to the second actuator 70, and the fourth wiring terminals 62 are all connected to the neutral wire. The second connection mode is to connect the neutral wire to the second actuator 70, and the fourth wiring terminals 62 are all connected to the live wire. Among them, the first connection mode is safer and can prevent construction workers from getting electric shock when wiring.

[0063] When construction workers need to install AC power equipment, they open the lock 80 on the outer box 10 and connect the AC power equipment to the corresponding third terminal 61 and fourth terminal 62. Then, the construction workers use the operation and maintenance terminal to send a power-on application signal to the remote control device. After receiving the power-on application signal, the remote control device forwards the power-on application signal to the approval terminal held by the approval personnel for approval. After the approval personnel approves the power-on application signal using the approval terminal, 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 actuator 70 to operate, and connects the third terminal 61 corresponding to the newly connected AC power equipment to the AC power line, so that the newly connected AC power equipment can work normally.

[0064] If the construction personnel open the outer box body 10 and make a wrong connection, and fail to connect the AC power equipment to the corresponding third terminal 61 and fourth terminal 62; the remote control device sends a power-on control signal to the controller 40, and the controller 40 controls the second actuator 70 to operate, and connects the third terminal 31 correctly corresponding to the newly connected AC power equipment to the AC power line; and since the construction personnel made a wrong connection, the AC power equipment cannot be used normally at this time, so the construction personnel can only make corrections and connect the AC power equipment to the corresponding third terminal 61 and fourth terminal 62.

[0065] by Figure 1 For example, the first wiring assembly 30 has 12 AC wiring terminal pairs. When the power switch is used on an iron tower, the 4 AC wiring terminal pairs on the left can be set as the AC wiring terminal pairs of the mobile operator, the 4 AC wiring terminal pairs in the middle can be set as the AC wiring terminal pairs of the Unicom operator, and the 4 AC wiring terminal pairs at the bottom can be set as the AC wiring terminal pairs of the telecom operator. When the construction personnel of the mobile operator need to install new electrical equipment, the construction personnel of the mobile operator have the authority to open the lock 80 on the outer box 10, and can open the lock 80 on the outer box 10, and can only connect the AC electrical equipment to the 4 AC wiring terminal pairs on the left, and can only connect to the third wiring terminal 61 and the fourth wiring terminal 62 set in advance among the 4 AC wiring terminals. After the mobile operator has connected the power-consuming equipment, the construction personnel use the operation and maintenance terminal to send a power-on application signal to the remote control device. After receiving the power-on application signal, the remote control device forwards the power-on application signal to the approval terminal held by the approval personnel for approval. After the approval personnel approves the power-on application signal using the approval terminal, 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 actuator 70 to operate, and connects the third terminal 61 corresponding to the newly connected power-consuming equipment to the AC power line, so that the newly connected AC power-consuming equipment can work normally. When using this power switch, other railway users such as Unicom operators and telecom operators follow the same operation process as the construction personnel of the above-mentioned mobile operators.

[0066] Furthermore, the second actuator 70 includes multiple groups of AC switch components corresponding to multiple groups of AC terminal pairs, and one AC switch component can control whether the third terminal 61 in one AC terminal pair is energized. Figure 3As shown, the AC switch assembly includes an electrically driven AC switch 71, a third busbar 72 and a fourth busbar 73. One end of the third busbar 72 and one end of the fourth busbar 73 are respectively connected to two main terminals of the electrically driven AC switch 71, the other end of the third busbar 72 is connected to the AC power line, and the other end of the fourth busbar 73 is connected to one of the third terminals 61. The controller 40 is connected to the two control terminals of the electrically driven AC switch 71 through wires to control the on and off of the electrically driven AC switch 71.

[0067] like Figure 3 As shown, the electrically driven AC switch 71 has four terminals, namely two main terminals and two control terminals. Figure 3 Taking the position shown as an example, there are two main terminals located on the right side of the electric drive AC switch 71, and the two main terminals are connected to the third busbar 72 and the fourth busbar 73 respectively; there are two control terminals located on the left side of the electric drive AC switch 71, and both control terminals are connected to the controller 40. The controller 40 can send a control signal to the electric drive AC switch 71 to connect or disconnect the two main terminals of the electric drive AC switch 71. Among them, the electric drive AC switch 71 can be a switch that can be opened and closed by a control current, such as a contactor or a relay.

[0068] Specifically, the electrically driven AC switch 71 has a normally open type, such as a normally open contactor, that is, when the two control terminals of the electrically driven AC switch 71 are not powered, the two main terminals are in a disconnected state; the electrically driven AC switch 71 also has a normally closed type, such as a normally closed contactor, that is, when the two control terminals of the electrically driven AC switch 71 are not powered, the two main terminals are in a connected state. The power switch can set the corresponding electrically driven AC switch 71 to be a normally open type or a normally closed type according to the requirements of different AC terminal pairs.

[0069] Continue to refer to Figure 3 The second actuator 70 further includes a second circuit breaker 74, and the end of the third busbar 72 away from the electrically driven AC switch 71 and the end of the third busbar 72 away from the electrically driven AC switch 71 are both connected to the second circuit breaker 74. The AC power line is connected to the third busbar 72 through the second circuit breaker 74, and a third terminal 61 is connected to the fourth busbar 73 through the second circuit breaker 74.

[0070] The circuit breaker has overload, short circuit and undervoltage protection functions and has the ability to protect the line and power supply. Since each AC switch assembly has a second circuit breaker 74, the power switch can protect the equipment connected thereto and prevent the electrical equipment from being damaged due to overload, short circuit and undervoltage during use. In addition, second circuit breakers 74 of different specifications can be set, for example, a 5A second circuit breaker 74 is set on some second actuators 70, and a 10A second circuit breaker 74 is set on some second actuators 70.

[0071] Reference Figure 3 The AC switch assembly also includes a current transformer 75, which is disposed on the third busbar 72 or the fourth busbar 74 and is electrically connected to the controller 40 to measure the current of the corresponding AC electrical equipment.

[0072] A module for collecting signals from the current transformer 75 is provided in the controller 40. The controller 40 is connected to the current transformer 75. The power consumption of the AC power equipment can be calculated according to the voltage of the AC power supply and the power consumption duration, so that the remote control device can control the on and off of the power equipment according to the power consumption of each power equipment.

[0073] Continue to refer to Figure 1 As shown, the power switch further includes an auxiliary wiring assembly 100 installed in the outer box 10, and the auxiliary wiring assembly includes a plurality of groups of DC terminal pairs having seventh terminals 101 and eighth terminals 102. Each seventh terminal 101 is connected to the first actuator 50, and each eighth terminal 102 is connected to the DC power line connected to the second terminal 32.

[0074] The auxiliary wiring assembly 100 is used to connect some auxiliary electrical equipment, such as temperature sensors, alarm devices, etc. When the construction personnel need to install auxiliary electrical equipment, they open the lock 80 on the outer box 10, connect the auxiliary electrical equipment to the corresponding seventh terminal 101 and eighth terminal 102, and then the construction personnel use the operation and maintenance terminal to send a power-on application signal to the remote control device. After receiving the power-on application signal, the remote control device forwards the power-on application signal to the approval terminal held by the approval personnel for approval. After the approval personnel approves the power-on application signal using the approval terminal, the approval terminal sends the approval signal to the remote control device, and the remote control device sends a power-on control signal to the controller 40. The controller 40 controls the first actuator 50 to operate, and connects the seventh terminal 101 corresponding to the newly connected AC electrical equipment to the DC power line, so that the newly connected auxiliary electrical equipment can work normally.

[0075] Similarly, if the construction personnel open the outer box body 10 and make a wrong connection, and fail to connect the auxiliary electrical equipment to the corresponding seventh terminal 101 and eighth terminal 102; the remote control device sends a power-on control signal to the controller 40, and the controller 40 controls the first actuator 50 to operate, and connects the seventh terminal 101 that correctly corresponds to the newly connected auxiliary electrical equipment to the DC power line; and since the construction personnel made a wrong connection, the auxiliary electrical equipment cannot be used normally at this time, so the construction personnel can only make corrections and connect the auxiliary electrical equipment to the corresponding seventh terminal 101 and eighth terminal 102.

[0076] Continue to refer to Figure 1 As shown, the power switch also includes a temporary wiring assembly 90 installed in the outer box 10, and the temporary wiring assembly 90 includes multiple groups of AC terminal pairs having fifth terminal 91 and sixth terminal 92; each fifth terminal 91 is connected to the second actuator 70, and each sixth terminal 92 is connected to the AC power line connected to the fourth terminal 62.

[0077] The temporary wiring assembly 90 is used for connecting temporary electrical equipment used by construction workers during the construction process, such as electric drills, lighting lamps, etc.

[0078] Open the lock 80 on the outer box 10, connect the temporary power equipment to the corresponding fifth terminal 91 and sixth terminal 92, and then the construction personnel use the operation and maintenance terminal to send a power-on application signal to the remote control device. After receiving the power-on application signal, the remote control device forwards the power-on application signal to the approval terminal held by the approval personnel for approval. After the approval personnel approves the power-on application signal using the approval terminal, 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 actuator 70 to operate, and connects the fifth terminal 91 corresponding to the newly connected temporary power equipment to the AC power line, so that the newly connected AC power equipment can work normally.

[0079] Similarly, if the construction personnel open the outer box 10 and make a wrong connection, and fail to connect the temporary power equipment to the corresponding fifth terminal 91 and sixth terminal 92; the remote control device sends a power-on control signal to the controller 40, and the controller 40 controls the second actuator 70 to operate, and connects the fifth terminal 91 correctly corresponding to the newly connected temporary power equipment to the AC power line; and because the construction personnel made a wrong connection, the temporary power equipment cannot be used normally at this time, so the construction personnel can only make corrections and connect the temporary power equipment to the corresponding fifth terminal 91 and sixth terminal 92.

[0080] The specific structure of the controller 40 is shown in FIG. Figure 5The controller 40 includes a connected microprocessor 41 and a communication module 42. The communication module 42 is connected to the remote control device signal, and is used to receive the control signal of the remote control device and transmit the control signal to the microprocessor 41. The first actuator 50 and the second actuator 70 are connected to the microprocessor 41, and the microprocessor 41 can control the first actuator 50 and the second actuator 70 to move according to the control signal.

[0081] Wherein, the communication module 42 can be a 458 communication module and / or an Internet of Things module. If the communication module 42 is a 458 communication module, the remote control device can adopt a construction monitoring system FSU of Tieba. If the communication module 42 is an Internet of Things module, the remote control device can adopt an Internet of Things server.

[0082] The microprocessor 41 is connected to the first actuator 50, and can transmit a corresponding current signal to the first actuator 50 according to the control signal, thereby controlling the first actuator 50 to operate, thereby controlling the connection and disconnection between the first terminal 31 and the DC power line, and also controlling the connection and disconnection between the seventh terminal 101 and the DC power line. The microprocessor 41 is also connected to the second actuator 70, and can transmit a corresponding current signal to the second actuator 70 according to the control signal, thereby controlling the second actuator 70 to operate, thereby controlling the connection or disconnection between the third terminal 61 and the AC power line, and also controlling the connection or disconnection between the fifth terminal 61 and the AC power line.

[0083] In addition, if Figure 5 As shown, the controller 40 further includes a plurality of current acquisition modules 43, which are electrically connected to the plurality of first actuators 50 in a one-to-one correspondence, and are used to acquire the current on each first actuator 50. Specifically, the current acquisition module 43 is connected to both ends of the shunt 55 on the first actuator 50, and can acquire the magnitude of the current flowing through the shunt 55.

[0084] like Figure 5 As shown, the lock 80 includes a mechanical actuator 81, a lock microcontroller 82 and a lock communication module 83. The lock communication module 83 is electrically connected to the lock microcontroller 82, and is used to receive an unlocking signal sent by a remote control device with unlocking authority, and send the unlocking signal to the lock microcontroller 82. The microprocessor 41 is electrically connected to the mechanical actuator 81, and can control the mechanical actuator 81 according to the control signal to open or close the lock 80.

[0085] The lock communication module 83 can be an Internet of Things module, a Bluetooth module, etc. The construction personnel have the right to open the lock 80 installed on the outer box 10, and the remote control device of the construction personnel can send an unlocking signal to the lock 80 on the outer box 10, the communication module 42 receives the unlocking signal, and the lock microcontroller 82 controls the mechanical actuator 81 to move and open the lock 80. The construction personnel do not have the right to open the lock 80 installed on the inner box 20, and the remote control device of the construction personnel cannot send an unlocking signal to the lock 80 on the inner box 20. Only a remote control device with the right to unlock the lock 80 on the inner box 20 can send an unlocking signal to the lock 80 of the inner box 20, such as the construction monitoring system FSU of Tieba.
