[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0036] Figure 1 is a structural diagram of a central switch cabinet centralized control device provided by an embodiment of the present invention, such as Figure 1As shown, the central switch cabinet centralized control device includes: an integrated control module 10, a wiring bar 20 and a circuit breaker module 30; the integrated control module 10 is connected to the circuit breaker module 30 through the wiring bar 20; the integrated control module 10 is integrated with a control panel 11 and a controller 12;

[0037] The control panel 11 includes a switch 111 and a live display 112; the controller 12 includes a switch control circuit 121, a first signal acquisition circuit 122 and a live display circuit 123; the switch 111 is electrically connected to the circuit breaker module 30 through the switch control circuit 121; the first signal acquisition circuit 122 is electrically connected to the live display 112 through the live display circuit 123;

[0038] The first signal acquisition circuit 122 is used to detect the input power information of the central switch cabinet;

[0039] The closing and opening switch 111 is used to receive local instructions and closing instructions so that the closing and opening control circuit 121 controls the circuit breaker module 30 to close according to the local instructions and closing instructions; it is also used to receive local instructions and opening instructions so that the closing and opening control circuit 121 controls the circuit breaker module 30 to open according to the local instructions and opening instructions; it is also used to receive remote instructions so that the closing and opening control circuit controls the circuit breaker module 30 to close according to the remote instructions and the remote closing signal; it is also used to receive remote instructions so that the closing and opening control circuit controls the circuit breaker module 30 to close according to the remote instructions and the remote opening signal.

[0040] Among them, the closing and opening transfer switch 111 of this embodiment outputs different instructions of remote closing, remote opening, local closing and local opening to the closing and opening control circuit 121 under the control of receiving various instructions from the user, and the closing and opening control circuit 121 performs different functions of remote closing, remote opening, local closing and local opening, so that the circuit breaker module 30 is closed and the circuit breaker module 30 is opened; when the circuit breaker module 30 is closed, the central switch cabinet outputs electric energy; when the circuit breaker module 30 is opened, the central switch cabinet does not output electric energy. The first signal acquisition circuit 122 can detect the input power information of the central switch cabinet, and then send the power information to the live display 112 through the live display circuit 123, so as to display the power information in real time;

[0041] Specifically, the power information includes the main bus power information and the cable room power information; the power display circuit 123 includes the main bus power display circuit and the cable room power display circuit; in this way, the main bus power display circuit and the cable room power display circuit respectively send the main bus power information and the cable room power information to the power display 112, thereby displaying different types of power information in real time.

[0042] It should be noted that a closing and opening switch 111 and a live display 112 may be provided on the control panel 11; the controller 12 includes a closing and opening control circuit 121, a first signal acquisition circuit 122 and a live display circuit 123; of course, other devices may be provided on the control panel 11, and the controller 12 may also include other circuits according to functional requirements, which are not limited here; the control panel 11 and the controller 12 are integrated into an integrated control module 10; the integrated control module 10 is connected to the circuit breaker module 30 through the wiring row 20; this avoids the problem that the prior art requires independent electrical design and wiring work from the switch cabinet control panel 11 through the terminal block of the low-voltage box and each control circuit, which will cause the wiring to be complicated;

[0043] In addition, the closing and opening switch 111 on the control panel 11 receives local instructions and closing instructions so that the closing and opening control circuit 121 controls the circuit breaker module 30 to close according to the local instructions and closing instructions; at the same time, it receives local instructions and opening instructions so that the closing and opening control circuit 121 controls the circuit breaker module 30 to open according to the local instructions and opening instructions; at the same time, it receives remote instructions so that the closing and opening control circuit 121 controls the circuit breaker module 30 to close according to the remote instructions and the remote closing signal; it also receives remote instructions at the same time so that the closing and opening control circuit 121 controls the circuit breaker module 30 to close according to the remote instructions and the remote opening signal, so that the local closing, local opening, remote closing and remote opening functions are realized by using a single closing and opening switch 11, which improves the space utilization rate of the integrated control module to be higher and the cost to be lower, and avoids the problem of low space utilization rate caused by using multiple conversion switches 11 to realize the local closing, local opening, remote closing and remote opening functions in the prior art.

[0044] Optional, Figure 2 is a schematic diagram of the structure of a switch for closing and opening a gate provided by an embodiment of the present invention, such as Figure 2 As shown, the closing and opening transfer switch 111 includes a single-pole four-throw rotary switch, and the model may be LW26-20; wherein, the closing and opening transfer switch 111 is a single-pole four-throw rotary switch, so that the single-pole four-throw rotary switch may include four states, corresponding to local, remote, closing and opening respectively; in this way, the functions of local closing, local opening, remote closing and remote opening may be completed on the same switch.

[0045] Optionally, based on the above embodiment, further refine and optimize, Figure 3 is a structural diagram of another central switch cabinet centralized control device provided by an embodiment of the present invention, such as Figure 3As shown, the control panel 11 further includes: a temperature and humidity controller 113 and a function indicator light 114; the controller 12 further includes: a second signal acquisition circuit 124, a temperature and humidity control circuit 125, a third signal acquisition circuit 126 and a status indication circuit 127;

[0046] The second signal acquisition circuit 124 is electrically connected to the temperature and humidity controller 113 via the temperature and humidity control circuit 125; the third signal acquisition circuit 126 is electrically connected to the function indicator light 114 via the status indication circuit 127;

[0047] The second signal acquisition circuit 124 is used to detect the temperature and humidity information of the central switch cabinet; the third signal acquisition circuit 126 is used to detect the status information of the circuit breaker module 30.

[0048] In the process of the central switch cabinet outputting electric energy, the third signal acquisition circuit 126 can detect the status information of the circuit breaker module 30 in real time; the status information includes the open state of the circuit breaker module 30, the closed state of the circuit breaker module 30 and the energy storage state of the circuit breaker module 30; thereby, the status information of the circuit breaker module 30 is sent to the function indicator light 114 through the status indication circuit 127, and the function indicator light 114 can indicate different status information of the circuit breaker module 30;

[0049] The center switch cabinet needs to maintain a certain temperature and humidity during the process of outputting electric energy. In this embodiment, the target temperature and humidity can be set on the temperature and humidity controller 113 of the control panel 11, and the second signal acquisition circuit 124 can detect the temperature and humidity information of the center switch cabinet. The temperature and humidity control circuit 125 can control the target temperature and humidity according to the temperature and humidity information of the center switch cabinet detected by the second signal acquisition circuit 124. Specifically, the temperature and humidity control circuit 125 includes a heating control circuit and a fan control circuit. When the detected temperature and humidity information of the center switch cabinet does not reach the target temperature and humidity, the heating control circuit can control the heating so that the temperature and humidity information of the center switch cabinet reaches the target temperature and humidity. When the detected temperature and humidity information of the center switch cabinet exceeds the target temperature and humidity, the fan control circuit can control the heating so that the temperature and humidity information of the center switch cabinet is reduced to the target temperature.

[0050] When a temperature and humidity controller 113 and a function indicator light 114 are added to the control panel 11; the controller 12 is additionally provided with a second signal acquisition circuit 124, a third signal acquisition circuit 126, a temperature and humidity control circuit 125 and a status indication circuit 127; the control panel 11 and the controller 12 are integrated into an integrated control module 10; the integrated control module 10 is connected to the circuit breaker module 30 through the terminal block 20; this avoids the problem in the prior art that independent electrical design and wiring work must be performed from the switch cabinet control panel 11 through the terminal block of the low-voltage box and each control circuit, which will cause the problem of complicated wiring. This greatly reduces the complexity of the wiring work and shortens the production cycle.

[0051] Optional, Figure 4 Schematic diagram of the structure of the closing and opening control circuit in the embodiment of the present invention; Figure 4 As shown, the closing and opening control circuit 121 includes: local signal terminals 1-2, closing signal terminals 5-6, opening signal terminals 7-8, remote signal terminals 3-4, remote control closing signal terminals 1211, remote control opening signal terminals 1212, closing pressure plate 1213, opening pressure plate 1214, circuit breaker closing coil 1215 and circuit breaker opening coil 1216;

[0052] The first end of the local signal terminal 1-2 and the first end of the remote signal terminal 3-4 are electrically connected to the high voltage source; the second end of the local signal terminal 1-2 is electrically connected to the first end of the closing signal terminal 5-6, and the second end of the closing signal terminal 5-6 is electrically connected to the circuit breaker closing coil 1215;

[0053] The second end of the local signal terminal 1-2 is electrically connected to the first end of the opening signal terminal 7-8; the second end of the opening signal terminal 7-8 is electrically connected to the circuit breaker opening coil 1216;

[0054] The second end of the remote signal terminal 3-4 is electrically connected to the first end of the remote control closing signal terminal 1211 and the first end of the remote control opening signal terminal 1212; the second end of the remote control closing signal terminal 1211 is electrically connected to the circuit breaker closing coil 1215 through the closing pressure plate 1213;

[0055] The second end of the remote-controlled opening signal terminal 1212 is electrically connected to the circuit breaker opening coil 1216 through the opening pressure plate 1214 .

[0056] Specifically, refer to Figure 2 and Figure 4, the control principle of the closing and opening control circuit 121 in this embodiment is: when the closing and opening transfer switch 111 receives a local command, the closing and opening transfer switch 111 rotates to a first preset angle, the closing and opening transfer switch is in a local state, and the local signal terminals 1-2 remain combined; then when the closing and opening transfer switch 111 receives a closing command, the closing and opening transfer switch 111 rotates to a second preset angle, the closing and opening transfer switch is in a closed state, the closing signal terminals 5-6 remain combined, and the local signal terminals 1-2 remain disconnected instantly, but because the signal on the local signal terminal 2 is still maintained at this time, the circuit breaker closing coil 1215 is energized, so that the circuit breaker module 30 is closed;

[0057] Generally, when the closing and opening switch 111 is rotated to the second preset angle, it will automatically reset to the first preset angle, and the closing and opening switch 111 will be in the local state, and the local signal terminals 1-2 remain combined; then when the closing and opening switch 111 receives the opening instruction, the closing and opening switch 111 rotates to the third preset angle, the closing and opening switch is in the opening state, the opening signal terminals 7-8 remain combined, and the local signal terminals 1-2 remain disconnected instantly, but because the signal on the local signal terminal 2 is still maintained at this time, the circuit breaker opening coil 1216 is energized, thereby opening the circuit breaker module 30; after opening, the closing and opening switch 111 will automatically reset to the local state of the first preset angle.

[0058] When the closing and opening transfer switch 111 receives a remote command, the closing and opening transfer switch 111 rotates to the fourth preset angle, and the closing and opening transfer switch 111 is in the remote state; if at this time, when a remote control closing signal is received, the remote control closing signal terminal 1211 remains combined; thereby, the circuit breaker module 30 is remotely closed; and if at this time, when a remote control opening signal is received, the remote control opening signal terminal 1212 remains combined; thereby, the circuit breaker module 30 is remotely opened; in this way, the closing and opening transfer switch 111 is used to realize the functions of local closing, local opening, remote closing and remote opening, thereby avoiding the problem of low space utilization caused by using multiple transfer switches 11 in the prior art to realize the functions of local closing, local opening, remote closing and remote opening.

[0059] It should be noted that the closing pressure plate 1213 can control the on-off of the remote closing control circuit; the opening pressure plate 1214 can control the on-off of the remote opening control circuit; in some safety emergency situations, the on-off of the remote closing control circuit and the remote opening control circuit can be controlled by controlling the on-off of the closing pressure plate 1213 and the opening pressure plate 1214, thereby controlling the on-off of the remote closing control circuit and the remote opening control circuit, thereby playing a role in safety protection.

[0060] Optionally, 5 is a schematic diagram of the structure of a central switch cabinet centralized control device provided by an embodiment of the present invention, such as Figure 5As shown, the controller 12 also includes: a communication circuit 128; the communication circuit 128 is connected to the closing and opening control circuit 121, and is used to send the position status information of the closing and opening switching switches to the background monitoring device; and is used to send the input status information of the closing pressure plate and the opening pressure plate to the background monitoring device.

[0061] Among them, the communication circuit 128 can send the position status information of the closing and opening transfer switch to the background monitoring device; at the same time, the input status information of the closing pressure plate and the opening pressure plate can be sent to the background monitoring device, so that the background monitoring device can actually output the remote control closing signal and remote control opening information based on the position status information of the closing and opening transfer switch, the input status information of the closing pressure plate and the opening pressure plate.

[0062] Optional, continue to Figure 5 The communication circuit 128 is also connected to the third signal acquisition circuit 126, and is used to send the status information of the circuit breaker module 30 to the background monitoring device. The communication circuit 128 sends the status information of the circuit breaker module 30 to the background monitoring device, so as to remotely control the closing and opening of the circuit breaker module 30 according to actual needs.

[0063] Optional, continue to Figure 5 The communication circuit 128 is also connected to the second signal acquisition circuit 124 and the temperature and humidity control circuit 125 for communication, and is used to send the temperature and humidity information of the central switch cabinet and the control information of the temperature and humidity control circuit to the background monitoring device. The communication circuit 128 also sends the temperature and humidity information of the central switch cabinet and the control information of the temperature and humidity control circuit to the background monitoring device, such as monitoring the temperature and humidity information of the central switch cabinet, the working state of the heating control circuit when the temperature and humidity information is less than the target temperature, and the working state of the fan control circuit when the temperature and humidity information is greater than the target temperature. In this way, the background monitoring device can effectively manage the temperature control information of the central switch cabinet.

[0064] Optionally, the controller 12 further includes a locking circuit (not specifically shown in the figure). Of course, it is understandable that the locking circuit can put the closing and opening control circuit in a locked state, that is, when the closing and opening control circuit 121 is working, the locking circuit can put the closing and opening control circuit in an invalid state. Of course, the locking circuit is electrically connected to the communication circuit, and the unlocking and locking states of the locking circuit can be sent to the background monitoring device in real time.

[0065] Optional, Figure 6 is a structural diagram of a central switch cabinet centralized control device provided by an embodiment of the present invention, such as Figure 6As shown, the controller 12 also includes: a fourth signal acquisition circuit 129 and a relay protection control circuit 130; the central switch cabinet centralized control device also includes: a relay protection device 40; the fourth signal acquisition circuit 129 is electrically connected to the relay protection device 40 through the relay protection control circuit 130; the fourth signal acquisition circuit 129 is used to detect and output the current and voltage information of the central switch cabinet so that the relay protection control circuit 130 outputs a relay protection signal to the relay protection device 40 according to the current and voltage information.

[0066] Among them, in the process of the central switch cabinet outputting electric energy, the fourth signal acquisition circuit 129 can detect and output the current and voltage information of the central switch cabinet, so that the relay protection control circuit 130 can output the relay protection signal to the relay protection device 40 according to the current and voltage information. For example, when the current and voltage information are respectively greater than the preset current and preset voltage values, that is, when an overcurrent fault, an overvoltage fault or a grounding fault occurs, a relay protection signal can be sent to the relay protection device 40, and the relay protection device 40 thereby realizes the protection of the electric energy output by the relay protection device 40.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
