Description

Technical Field

[0001] The present invention relates to the technical field of remote control, in particular to a remote control switch for a power distribution cabinet and a power distribution cabinet. Background Art

[0002] As a key component of the power system, the power distribution cabinet is widely used in various industrial, commercial and civil buildings. Its core function is to distribute electrical energy to various electrical equipment safely and efficiently. With the advancement of technology and the increase in intelligent demand, the power distribution cabinet has gradually integrated remote control switch technology. Remote control switch technology allows operators to monitor and control the switches in the power distribution cabinet in real time through the local area network or the Internet, and can realize the circuit on and off, status monitoring and fault warning without going to the site in person. This technology not only greatly improves the flexibility and efficiency of power management, but also effectively reduces the risk and cost of manual intervention.

[0003] The Chinese patent application number 2021114427924 discloses a remotely controllable power distribution cabinet, including a control panel, a main switch, a main fuse, a sub-switch, a sub-fuse, and a shell. The control panel is electrically connected to the main switch and the sub-switch. The control panel is provided with a processor module and a network module. An operating system or a virtual operating system is installed in the processor module. The operating system is provided with power distribution cabinet management software and remote control software. The power distribution cabinet management software can control the closing or disconnection of the main switch and the sub-switch. The power distribution cabinet management software can modify the name of the sub-switch and the name of the sub-fuse so that the power supply area controlled by the sub-switch and the sub-fuse can be directly seen. The name, device number, and connection password of the remote control software are marked on the shell so that the processor module can be connected to the main control end as the controlled end. The invention sets a network module and remote control software in the control panel to make the power distribution cabinet remotely controllable, facilitate power supply management, reduce the occurrence of safety accidents, and improve work efficiency.

[0004] Similar to the remote control switch of the above-mentioned prior art, when the electrical switch in the distribution cabinet is remotely controlled to be closed through the local area network or the Internet, the shunt release is usually energized through the remote control signal control cable or control module, so that the shunt release drives the switch to close the switch. However, due to the structural limitations of the shunt release, the release in the prior art can only close the switch and still needs to be opened manually, which poses certain safety hazards and cannot achieve remote control of the switch.

[0005] At the same time, when the switch command is sent to the control module or control cable through the terminal, the control module or control cable controls the shunt release to perform the switch operation after receiving the command. However, during long-term use, the metal contact surface of the shunt release may cause poor contact due to rust, oxidation or damage, or the mechanical parts inside the circuit breaker may be stuck due to wear, deformation or foreign matter. At this time, the shunt release cannot drive the switch to the required position. At this time, the switch status displayed on the terminal deviates from the actual switch status, which can easily cause maintenance personnel to misjudge the status of the distribution cabinet, resulting in casualties.

[0006] Furthermore, if the current in the circuit breaker is too large, the shunt release may be unable to drive the switch to close or trip. At this time, if the shunt release is forcibly controlled to toggle the switch to close, fire and explosion may easily occur. The prior art lacks a remote control switch that can detect the status inside the distribution cabinet and perform different processing according to different status.

[0007] Therefore, it is necessary to invent a remote control switch and a distribution cabinet for a distribution cabinet to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] To remotely control the switch of the power distribution cabinet, Figure 1 - Figure 8 As shown, the first embodiment of the present invention provides a remote control switch for a power distribution cabinet, including a support portion 1, a plurality of circuit breakers 5 are arranged in the support portion 1, and the remote control switch also includes: The receiving part 2 is arranged on the supporting part 1 , and the receiving part 2 can receive instructions sent by the terminal and send instructions to the terminal.

[0032] The control unit 3 is disposed on the support unit 1 and is electrically connected to the receiving unit 2. The control unit 3 can control various electrical components to perform operations.

[0033] The executing part 4 is arranged on the supporting part 1 , and a plurality of the executing parts 4 are electrically connected to a control part 3 . The control part 3 can control different executing parts 4 to perform operations according to the instructions received by the receiving part 2 .

[0034] In this embodiment, the execution part 4 includes a first tripping component 41 and a second tripping component 42. The first tripping component 41 and the second tripping component 42 are arranged in the support part 1. The first tripping component 41 can close the circuit breaker 5 according to the instruction of the control part 3, and the second tripping component 42 can open the circuit breaker 5 according to the instruction of the control part 3.

[0035] In this embodiment, the first tripping assembly 41 is specifically a shunt release, and the first tripping assembly 41 includes a coil, an electromagnet, an armature, a transmission assembly and a tripping mechanism. The first tripping assembly 41 can energize the coil arranged in the first tripping assembly 41 through the instruction of the control unit 3, so that the electromagnet generates magnetic attraction to move the armature, and drives the transmission mechanism to push the tripping mechanism to close the circuit breaker 5.

[0036] It should be noted that the shunt release is a common electrical component in the prior art, and therefore will not be described in detail in the present invention.

[0037] In this embodiment, the second trip assembly 42 includes a hinge 421, one end of the hinge 421 is movably connected to the switch of the circuit breaker 5, and the other end of the hinge 421 is provided with a rotating shaft 422. The two ends of the rotating shaft 422 away from the hinge 421 are respectively provided with a limit member 423, and a fixing member 424 is provided at the bottom of the limit member 423. The fixing member 424 is provided with a sliding groove adapted to the limit member 423, and the limit member 423 can slide on the fixing member 424.

[0038] In this embodiment, the second release assembly 42 also includes a connecting member 425, which is arranged on the support portion 1. The interior of the connecting member 425 is a hollow structure. A plurality of fixing members 424 are fixed on one side of the connecting member 425. Each fixing member 424 is provided with a detection member 426. One end of the detection member 426 is fixedly connected to the limit member 423, and the other end of the detection member 426 passes through the connecting member 425 and extends into the interior of the connecting member 425.

[0039] In this embodiment, the detection member 426 located in the connecting member 425 is fixedly connected to the permanent magnet 428 at one end away from the fixing member 424, and a plurality of sliding rods 6 are provided at the end of the permanent magnet 428 away from the detection probe 427. A plurality of through grooves 7 adapted to the sliding rods 6 are provided in the connecting member 425. The permanent magnet 428 can slide in the connecting member 425 through the sliding rods 6. A plurality of electromagnetic members 429 corresponding to the permanent magnet 428 are provided on the side of the inner cavity of the connecting member 425 close to the permanent magnet 428.

[0040] During use, when it is necessary to remotely control multiple circuit breakers 5 to perform power-off operations, a power-off command is sent to the receiving part 2 through the terminal. After receiving the power-off command, the receiving part 2 conveys the command to the control part 3, so that the control part 3 controls the first tripping component 41 to perform the closing operation. During this process, the coil in the first tripping component 41 is energized through the control part 3, so that the electromagnet generates magnetic attraction to move the armature, and drives the transmission mechanism to push the tripping mechanism to move the switch of the circuit breaker 5 away from the second tripping component 42, thereby cutting off the power supply to the circuit breaker 5. At this time, since the electromagnetic component 429 is not energized, the magnetic attraction between the permanent magnet component 428 and the electromagnetic component 429 is less than the pulling force of the switch of the circuit breaker 5 on the hinge 421. Therefore, under the pulling of the hinge 421, the limit component 423 can move in the direction away from the connecting component 425, thereby realizing the remote power-off operation of multiple circuit breakers 5.

[0041] When it is necessary to remotely control multiple circuit breakers 5 for power-on operation, a power-on command is sent to the receiving part 2 through the terminal. After receiving the power-off command, the receiving part 2 transmits the command to the control part 3, so that the control part 3 controls multiple electromagnetic parts 429 to be powered on at the same time. In this process, by adjusting the power-on direction of the electromagnetic part 429, the magnetic attraction between the electromagnetic part 429 and the permanent magnet part 428 is increased. At this time, the magnetic attraction between the electromagnetic part 429 and the permanent magnet part 428 is greater than the force of the first tripping assembly 41 on the circuit breaker 5. Therefore, the permanent magnet part 428 can move in the direction close to the electromagnetic part 429 under the action of the magnetic attraction, so that the detection part 426 connected to the permanent magnet part 428 pulls the limit part 423 to move in the direction close to the connecting part 425, so that the hinge part 421 pulls the switch of the circuit breaker 5 to move in the direction close to the connecting part 425, thereby realizing the remote power-on operation of multiple circuit breakers 5, and at the same time, the first tripping assembly 41 is reset, so as to facilitate the next remote control of the circuit breaker 5 for power-off operation.

[0042] In order to improve the application of the remote control switch in the distribution cabinet, in another embodiment of the present invention, a distribution cabinet is also provided, which includes the above-mentioned remote control switch. The distribution cabinet also includes a box body 8, on which an alarm unit 9 is provided. The alarm unit 9 is electrically connected to the control unit 3, and the control unit 3 can control the alarm unit 9 to generate alarm information.

[0043] In this embodiment, a frequency conversion unit 10 and a heat dissipation unit 11 are further provided in the box body 8. The frequency conversion unit 10 can adjust the power distribution according to the load conditions, and the heat dissipation unit 11 can dissipate heat for various electrical components in the power distribution cabinet.

[0044] In this embodiment, a plurality of support parts 1 are arranged in the box body 8, and each electrical component in the box body 8 can be fixed in the box body 8 through the support parts 1. The box body 8 is also provided with a first cabinet door and a second cabinet door. The first cabinet door is arranged on the inner side of the second cabinet door. The first cabinet door is provided with an insulating layer, and the second cabinet door is provided with an explosion-proof layer.

[0045] However, during long-term use, the metal contact surface of the first trip component 41 may have poor contact due to rust, oxidation or damage, or the mechanical parts inside the circuit breaker 5 may be stuck due to wear, deformation or foreign matter. At this time, the first trip component 41 cannot drive the switch to the desired position. At this time, the switch state displayed on the terminal deviates from the actual switch state, which may easily cause maintenance personnel to misjudge the state of the distribution cabinet and cause casualties; and if the current in the circuit breaker 5 is too large, the first trip component 41 may be unable to drive the switch to close or trip. At this time, if the first trip component 41 is forcibly controlled to toggle the switch to close, fire and explosion may easily occur. The prior art lacks a remote control switch that can detect the state inside the distribution cabinet and perform different processing according to different states.

[0046] To solve the above technical problems, in another embodiment of the present invention, the remote control switch also includes: a feedback part is also provided in the support part 1, and the feedback part is electrically connected to the execution part 4 and the receiving part 2 respectively. The feedback part can feed back the motion state parameters of the execution part 4 to the receiving part 2, and transmit the information to the terminal through the receiving part 2.

[0047] In this embodiment, a plurality of identification modules are provided in a linear array on the detection member 426 located in the connection member 425. The second tripping assembly 42 can detect the switch movement stroke of the circuit breaker 5 and assist the first tripping assembly 41 in closing the circuit breaker 5. In this embodiment, a plurality of detection probes 427 are provided inside the connecting member 425 , and the plurality of detection probes 427 correspond one-to-one to the plurality of detection members 426 . The detection probes 427 can identify the plurality of identification modules on the detection member 426 , thereby determining the moving range of the limiting member 423 .

[0048] During use, when it is necessary to remotely control multiple circuit breakers 5 to perform a power-off operation, a power-off command is sent to the receiving part 2 through the terminal. After receiving the power-off command, the receiving part 2 conveys the command to the control part 3, so that the control part 3 controls the first tripping component 41 to perform a closing operation, and at the same time, the control part 3 causes the detection probe 427 to operate. When the limit member 423 moves in a direction away from the connecting member 425 driven by the hinge 421, the limit member 423 can drive the detection member 426 to slide in a direction away from the electromagnetic member 429, so that the identification modules set on the detection member 426 pass through the detection probe 427 in turn, and the detection probe 427 identifies and records the multiple identification modules, so as to determine whether the first tripping component 41 drives the switch of the circuit breaker 5 to move to the preset position. If the number of identification modules detected by the detection probe 427 is equal to the preset value, it means that the first tripping component 41 can drive the switch of the circuit breaker 5 to move to the closing position.

[0049] If the number of identification modules detected by the detection probe 427 is less than the preset value, it means that the first tripping component 41 is unable to drive the switch of the circuit breaker 5 to move to the closed position. At this time, the data is fed back to the control unit 3, so that the control unit 3 controls the electromagnetic component 429 to be energized, and adjusts the energization direction of the electromagnetic component 429, so that a magnetic repulsion force is generated between the electromagnetic component 429 and the permanent magnet component 428, thereby pushing the permanent magnet component 428 to drive the detection component 426 to move through the magnetic repulsion force, so that the limit member 423 connected to the detection component 426 can drive the switch of the circuit breaker 5 to move in the closing direction again through the hinge 421, thereby avoiding the metal contact surface of the first tripping component 41 from being rusted, oxidized or damaged, resulting in poor contact, or the mechanical parts inside the circuit breaker 5 from being stuck due to wear, deformation or foreign matter, and the first tripping component 41 cannot drive the switch to move to the desired position. At this time, the switch state displayed on the terminal deviates from the actual switch state, which can easily cause maintenance personnel to misjudge the state of the distribution cabinet, resulting in casualties.

[0050] When it is necessary to remotely control multiple circuit breakers 5 to perform power-on operations, a power-on command is sent to the receiving unit 2 through the terminal. After receiving the power-off command, the receiving unit 2 transmits the command to the control unit 3, so that the control unit 3 controls multiple electromagnetic components 429 to be powered on at the same time. In this process, the power-on direction of the electromagnetic component 429 is adjusted to increase the magnetic attraction between the electromagnetic component 429 and the permanent magnetic component 428. At this time, the magnetic attraction between the electromagnetic component 429 and the permanent magnetic component 428 is greater than the force of the first tripping component 41 on the circuit breaker 5. Therefore, the permanent magnetic component 428 can be powered on by the magnetic attraction. The detection member 426 connected to the permanent magnet member 428 pulls the limit member 423 to move toward the direction close to the connecting member 425, so that the hinge member 421 pulls the switch of the circuit breaker 5 to move toward the direction close to the connecting member 425. During this process, the detection probe 427 is used to continuously identify and record the multiple identification modules on the detection member 426 in turn. If the number of identification modules detected by the detection probe 427 is equal to the preset range, it means that the multiple circuit breakers 5 are normally powered on.

[0051] If at this time, when the magnetic attraction between the electromagnetic component 429 and the permanent magnetic component 428 has not changed, and the number of identification modules detected by the detection probe 427 is always less than the preset range, it means that the current in the circuit breaker 5 is too large, resulting in the switch of the circuit breaker 5 being unable to move to the preset position. At this time, the information parameter is fed back to the receiving unit 2 through the feedback unit, and the receiving unit 2 sends information to the terminal to prompt the operator that there is an abnormality here, and the control unit 3 controls the alarm unit 9 to send an alarm message to prevent people from approaching the distribution cabinet and causing casualties.

[0052] If at this time, when the magnetic attraction between the electromagnetic component 429 and the permanent magnet component 428 has not changed, the number of identification modules detected by the detection probe 427 is equal to the preset value when the electromagnetic component 429 is powered on, and when the electromagnetic component 429 is powered off, the number of identification modules detected by the detection probe 427 changes again, then it means that the circuit breaker 5 has tripped. At this time, the information parameters are fed back to the receiving unit 2 through the feedback unit, and the receiving unit 2 sends information to the terminal to prompt the operator that there is an abnormality here, and the control unit 3 controls the alarm unit 9 to send an alarm message to prevent people from approaching the distribution cabinet and causing casualties.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
