Description

Technical Field

[0001] This utility model relates to the technical field of equipment status monitoring, and in particular to a switch status monitoring device. Background Technology

[0002] To better monitor the on / off status of switches, several status monitoring devices have emerged on the market. For example, Chinese invention patent application CN115910706A, entitled "Accessory for a Circuit Breaker Handle, Accessory for a Circuit Breaker, and Circuit Breaker," includes a magnet, a magnetic induction switch, and an indicator unit. The magnet is positioned on the circuit breaker's housing, corresponding to the position of the handle when the circuit breaker is in the tripped position. The indicator unit is mounted on the circuit breaker's handle and is configured to illuminate its indicator light in response to the magnetic induction switch's conduction. When the circuit breaker is in the tripped position, the magnetic induction switch interacts with the magnet to conduct. However, since this solution only provides on-site indication, it is difficult for monitoring personnel to promptly detect abnormalities in power distribution lines where switches are located in dispersed locations. Utility Model Content

[0003] The purpose of this utility model is to provide a switch status monitoring device, which has the advantages of reasonable design, simple structure, and remote monitoring of the switch's working status.

[0004] The technical solution adopted by this utility model is: a switch status monitoring device, including a magnetic component, a magnetic induction component and a read / write module; the magnetic component is disposed on the operating part of the switch, and the magnetic component can be driven by the operating part of the switch to approach and trigger the magnetic induction component; the read / write module is wirelessly connected to the magnetic induction component and electrically connected to an external monitoring center, and the read / write module is used to read the trigger information of the magnetic induction component and transmit it to the external monitoring center, and to wirelessly power the magnetic induction component.

[0005] The working principle of this utility model is as follows:

[0006] In use, if the switch has only two operating states (closed and open), the position of the magnetic induction component corresponds to the position of the magnetic element when the switch is in the open or closed state. If the switch has three operating states (closed, open, and trip), the position of the magnetic induction component corresponds to the position of the magnetic element when the switch is in the trip or closed state. Taking the correspondence between the magnetic induction component and the magnetic element when the switch is closed as an example, when the switch is closed, the magnetic element is moved closer to the magnetic induction component by the switch's operating part. The read / write module supplies power to the magnetic induction component via electromagnetic waves, causing the magnetic induction component to operate and be triggered by the magnetic element. The magnetic induction component returns the trigger information to the read / write module via electromagnetic waves, and the read / write module transmits the trigger information to the external monitoring center, thus informing the external monitoring center that the switch is in the closed state. When the switch changes state, the magnetic element is moved away from the magnetic induction component by the switch's operating part, and the read / write module does not receive the returned trigger information. The external monitoring center can then remotely detect the change in the switch's operating state. This design allows the external monitoring center to remotely monitor the switch's state in conjunction with this state monitoring device. In addition, when the read / write module is working, it cyclically and sequentially exchanges information and supplies power to the magnetic induction components of multiple switches in the same area, thereby enabling a single read / write module to monitor the status of multiple switches in the same area. This simplifies the circuit structure between the magnetic induction components and the external monitoring center, making the wiring more convenient.

[0007] Furthermore, in the aforementioned switch status monitoring device, the magnetic induction component includes a reed switch, a recording module, and a passive antenna; the reed switch is triggered and turned on by a nearby magnetic component, and both ends of the reed switch are electrically connected to the recording module; the recording module is used to record the status information of the reed switch, and the recording module is electrically connected to the passive antenna; the passive antenna is wirelessly connected to the read / write module, and the passive antenna is used for information transmission between the recording module and the read / write module, and to supply power to the recording module.

[0008] Furthermore, in the aforementioned switch status monitoring device, the magnetic induction component further includes an insulating substrate. A mounting recess is formed on one side of the insulating substrate, and two wiring terminals are provided on the front side of the insulating substrate. The two wiring terminals are respectively located on both sides of the mounting recess. The reed switch is located in the mounting recess of the insulating substrate, and the two ends of the reed switch are connected to the two wiring terminals one by one. The recording module and the passive antenna are both located on the front side of the insulating substrate, and the recording module is connected to the two wiring terminals.

[0009] Furthermore, in the aforementioned switch status monitoring device, the magnetic induction component further includes a housing, which comprises a casing and a base plate. The casing and the base plate are detachably assembled together to enclose and form a mounting cavity, in which the insulating substrate, reed switch, recording module, and passive antenna are all located.

[0010] Furthermore, in the switch state monitoring device described above, the number of magnetic induction components is at least two, with one magnetic induction component corresponding to one of the switch states. The magnetic component can be driven by the switch's operating part to approach and trigger the magnetic induction component corresponding to the switch state.

[0011] The advantages of this utility model are: reasonable design, simple structure, and remote monitoring of the working status of the switch. Attached Figure Description

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example

[0023] like Figures 1 to 3The switch status monitoring device of Embodiment 1 includes a magnetic component 3, two magnetic induction components 2, and a read / write module (the read / write module is not shown in the accompanying drawings).

[0024] The switch 1 is a circuit breaker, and the switch 1 has three working states: closed, open and tripped.

[0025] The magnetic component 3 is a magnet, and it is mounted on the operating part 11 of the switch 1. Two magnetic induction components 2 are respectively called the first magnetic induction component and the second magnetic induction component. The position of the first magnetic induction component corresponds to the position of the magnetic component 3 when the switch 1 is closed, and the position of the second magnetic induction component corresponds to the position of the magnetic component 3 when the switch 1 is open. Each magnetic induction component 2 includes a reed switch 23, a recording module 24, and a passive antenna 25. The reed switch 23 is triggered and turned on by the nearby magnetic component 3. Both ends of the reed switch 23 are electrically connected to the recording module 24. The recording module 24 is used to record the status information of the reed switch 23 and is electrically connected to the passive antenna 25. The passive antenna 25 is wirelessly connected to the read / write module and is used for information transmission between the recording module 24 and the read / write module, as well as for powering the recording module 24. The read / write module is electrically connected to an external monitoring center and is used to transmit the status information of each magnetic induction component 2 to the external monitoring center.

[0026] The magnetic component 3 can be driven by the operating part 11 of the switch 1 to approach the reed switch 23 of the corresponding magnetic induction component 2. That is, when the switch 1 is in the closed state, the magnetic component 3 approaches and triggers the reed switch 23 of the first magnetic induction component. When the switch 1 is in the open state, the magnetic component 3 approaches and triggers the reed switch 23 of the second magnetic induction component. When the switch 1 is in the tripped state, the magnetic component 3 is between the first magnetic induction component and the second magnetic induction component and does not trigger any magnetic induction component 2.

[0027] The working principle of this embodiment is as follows:

[0028] When switch 1 is in the closed state, the magnetic element 3 is driven by the operating part 11 of switch 1 to approach the reed switch 23 of the first magnetic induction component, so that the reed switch 23 of the first magnetic induction component is triggered by the magnetic element 3 and becomes conductive. The read-write module supplies power to the recording module 24 of each magnetic induction component 2 through electromagnetic waves, so that the recording module 24 of each magnetic induction component 2 works. The recording module 24 of the first magnetic induction component records the conductive state information, and the recording module 24 of the second magnetic induction component records the open circuit state information. The passive antenna 25 of each magnetic induction component 2 returns the state information recorded by its recording module 24 to the read-write module. The read-write module transmits the state information of each magnetic induction component 2 to the external monitoring center, so that the external monitoring center knows that switch 1 is in the closed state.

[0029] When switch 1 is in the open state, the magnetic element 3 is driven by the operating part 11 of switch 1 to approach the reed switch 23 of the second magnetic induction component, so that the reed switch 23 of the second magnetic induction component is triggered by the magnetic element 3 and turns on. The read-write module supplies power to the recording module 24 of each magnetic induction component 2 through electromagnetic waves, so that the recording module 24 of each magnetic induction component 2 works. The recording module 24 of the first magnetic induction component records the open circuit status information, and the recording module 24 of the second magnetic induction component records the on circuit status information. The passive antenna 25 of each magnetic induction component 2 returns the status information recorded by its recording module 24 to the read-write module. The read-write module transmits the status information of each magnetic induction component 2 to the external monitoring center, so that the external monitoring center knows that switch 1 is in the open state.

[0030] When switch 1 is in the tripped state, the magnetic component 3 is driven by the operating part 11 of switch 1 and is positioned between the first magnetic induction component and the second magnetic induction component. The reed switches 23 of the first magnetic induction component and the second magnetic induction component are not triggered. The read / write module supplies power to each magnetic induction component 2 through electromagnetic waves to make each magnetic induction component 2 work. The recording module 24 of the first magnetic induction component records the open circuit status information, the recording module 24 of the second magnetic induction component records the open circuit status information, and the read / write module transmits the status information of each magnetic induction component 2 to the external monitoring center. The external monitoring center then knows that switch 1 is in the tripped state.

[0031] This design enables an external monitoring center to remotely monitor the status of switch 1 in conjunction with this status monitoring device. Furthermore, during operation, the read / write module sequentially exchanges information and supplies power to the magnetic induction components 2 of multiple switches 1 within the same area. This allows a single read / write module to monitor the status of multiple switches 1 within the same area, simplifying the circuit structure between the magnetic induction components 2 and the external monitoring center, and making wiring more convenient.

[0032] like Figure 2 and 3 As shown, the magnetic induction component 2 also includes an insulating substrate 22. A mounting recess 221 is formed on one side of the insulating substrate 22. Two terminals 26 are provided on the front side of the insulating substrate 22, located on opposite sides of the mounting recess 221. A reed switch 23 is located within the mounting recess 221 of the insulating substrate 22, with both ends of the reed switch 23 connected to the two terminals 26 respectively. The recording module 24 and the passive antenna 25 are both located on the front side of the insulating substrate 22, and the recording module 24 is connected to the two terminals 26. By placing the reed switch 23 within the mounting recess 221, the assembly structure of the components of the magnetic induction component 2 becomes more compact, reducing the space occupied by the magnetic induction component 2 and making it suitable for different types of switches 1.

[0033] like Figures 1 to 3 As shown, the magnetic induction component 2 also includes a housing 21, which comprises a shell 211 and a base plate 212. The shell 211 and the base plate 212 are detachably assembled together to form a mounting cavity, within which the insulating substrate 22, reed switch 23, recording module 24, and passive antenna 25 are all housed. This design prevents the reed switch 23, recording module 24, and passive antenna 25 from being directly exposed to the external environment, thus providing dust protection. In this embodiment, the base plates 212 of the two magnetic induction components 2 are connected as a single unit, facilitating the simultaneous installation and removal of the two magnetic induction components 2. Example

[0034] like Figure 4 and Figure 5 This is a switch status monitoring device according to Embodiment 2. The difference between Embodiment 2 and Embodiment 1 is that the switch 1 in this embodiment only has two working states: closed and open. The operating part 11 of the switch 1 is provided with a conductor. One end of the conductor in the operating part 11 is rotatably connected to one terminal of the switch 1. The operating part 11 is rotated to connect the other end of its conductor to the other terminal of the switch 1, thereby achieving the closing of the switch 1. This embodiment only has one magnetic induction component 2, and the position of the magnetic induction component 2 corresponds to the position of the magnetic component 3 when the switch 1 is in the closed state. Example

[0035] like Figures 6 to 8 This is a switch status monitoring device according to Embodiment 3. Embodiment 3 differs from Embodiment 1 in that the switch 1 in this embodiment has only two working states: closed and open. The operating part 11 of the switch 1 is equipped with a conductor. The middle of the operating part 11 is rotatably mounted on the switch 1, and the rotation axis of the operating part 11 is located between the two terminals of the switch 1. By rotating the operating part 11, the two ends of its conductor are connected to the two terminals of the switch 1 respectively, thereby achieving the closing of the switch 1. This embodiment only has one magnetic induction component 2, and the position of the magnetic induction component 2 corresponds to the position of the magnetic component 3 when the switch 1 is in the closed state.
