Traditional temperature sensors use batteries, but battery power is limited by battery life, and replacing batteries after their lifespan is difficult; furthermore, the need for periodic battery replacement leads to high maintenance costs. Some traditional temperature sensors also rely on external power adapters; however, external power adapters require additional wiring and cables, significantly increasing costs. Therefore, improvements to traditional sensing devices are desired. Summary of the Invention

This contact allows the formation of a closed magnetic flux loop, ensuring the magnetic flux coupling strength between the first and second sensing segments.

[0014] In some embodiments, the first mating portion includes an inclined opening, the inclined opening including a first inclined surface, and the magnetic coupling end of the first sensing segment is at least partially disposed on the first inclined surface. The second mating portion includes an inclined protrusion, the inclined protrusion including a second inclined surface, and the magnetic coupling end of the second sensing segment is at least partially disposed on the second inclined surface.

[0016] In some embodiments, the base includes a spacer extending between the magnetically coupled ends of the first sensing segment and at least partially inserted into the housing when the first and second mating portions contact each other. This further ensures reliable magnetic flux coupling between the first and second sensing segments.

[0028] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0029] The term "comprising" and its variations as used herein signify an open-ended inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". Terms such as "upper", "lower", "front", and "rear", indicating placement or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are used only for the purpose of describing the principles of this disclosure, and are not intended to indicate or imply that the elements referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as limiting this disclosure.

[0030] As mentioned earlier, power distribution networks, such as those in industrial sites, require a large number of conductors (such as busbars) to meet the power supply needs of different areas. However, these networks typically also require multiple sensing devices. For example, these sensing devices may include temperature sensors positioned at different locations on the busbars. By detecting the temperature of these busbars or busbar joints, the power supply status of the network and / or the power consumption of the equipment can be determined. These sensing devices typically include processors and require DC power to ensure proper operation.

[0031] The embodiments of this disclosure provide a simple way to power a sensing device. According to the embodiments of this disclosure, power can be drawn from the busbar inductively to power the sensing device. Specifically, the power supply module of the sensing device can be divided into two parts, wherein a first part can be installed to the busbar, and a second part, incorporating a temperature sensing device, can be detachably installed to the first part. When the second part and the first part are engaged, electromagnetic coupling between the two parts enables inductive power draw. This split design allows for easy installation and maintenance of the sensing device without requiring a power outage. It is worth noting that although the embodiments of this disclosure use a sensing device as an example of a power-consuming device, the inventive concept of the embodiments of this disclosure can be applied to any other electrical equipment used for a busbar or conductor.

[0032] The operating principle of the sensing device 100 for a busbar device according to an embodiment of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0033] Figure 1 and Figure 2 A general schematic diagram of a sensing device for a busbar assembly according to an embodiment of the present disclosure is shown. Figure 1 The diagram shows the state in which the functional body 20 is installed to the conductor connector 12. Figure 2 The diagram shows the state of the functional unit being detached from the conductor connector. (Example) Figure 1 and Figure 2 As shown, the busbar assembly 200 may include a busbar assembly and includes multi-phase conductors 30 (also referred to as busbars 30) arranged adjacent to each other and busbar insulation trays 210. The conductors may be, for example, two-phase, three-phase, or four-phase and are suitable for transmitting power. Figure 1 In the embodiment shown, conductor connector 12 is adapted to be attached to busbar insulation plate groove 210 of sensing device 100, and busbar insulation plate is adapted to hold conductor 30 in a fixed manner.

[0034] The sensing device 100 may include two parts: a conductor connector 12 and a functional body 20. The conductor connector 12 may be pre-arranged on the sensing device 100 and may be shaped to accommodate an interface for the functional body 20. For example, in Figure 1In the embodiment shown, conductor connector 12 is adapted to be attached to busbar insulation plate groove 210 of sensing device 100, and busbar insulation plate is adapted to hold conductor 30 in a fixed manner.

[0035] The functional body 20 may include a functional unit and a main connector 22 capable of engaging with the conductor connector 12. The conductor connector 12 may include a first sensing section 14 configured to generate a changing magnetic field in response to changes in the current flowing through the conductor 30. The main connector 22 includes a second sensing section 24 adapted to be magnetically coupled to the first sensing section 14 to form a magnetic flux loop. When the main connector 22 and the conductor connector 12 are engaged, thereby mounting the sensing device on the busbar, the sensing device can operate normally after the busbar is energized. Specifically, the second sensing section 24 is magnetically coupled to the first sensing section 14 to form a magnetic flux loop. Thus, the magnetic flux loop formed by the magnetic coupling of the second sensing section 24 and the first sensing section 14 can generate a change in magnetic flux in response to changes in the current flowing through the conductor 30. For example, a power supply coil disposed in the functional body 20 may be electromagnetically coupled to this magnetic flux loop to generate electricity, thereby powering the functional unit.

[0036] The first sensing section 14 and the second sensing section 24 may be made of a magnetically inductive material. In some embodiments, the first sensing section 14 and the second sensing section 24 may be made of silicon steel sheet. It is worth noting that this is merely exemplary, and the first sensing section 14 and the second sensing section 24 may be made of any other suitable magnetically inductive material.

[0037] In some embodiments, the functional body 20 may be secured to the conductor connector 12 or the insulating plate supporting the conductor connector 12 by fasteners such as screws. It is worth noting that this is merely exemplary, and the functional body 20 may be mechanically connected to the conductor connector 12 by any other suitable means.

[0038] like Figure 1 and Figure 2 As shown, the functional unit may include a sensing electrode 29 and an antenna 27. The electrode 29 may be adapted to contact the conductor 30 at an appropriate location. The acquired data is processed by a processor and converter within the functional unit 20, and the processed data can be transmitted to an upstream node via the antenna 27. It is worth noting that the processed data can also be transmitted via a wired network.

[0039] In some embodiments, the functional body 20 further includes an induction coil adapted for electromagnetic coupling with a magnetic flux loop. As an example, a PCB board with the induction coil mounted is fixed inside the housing of the functional body 20, and power supply lines are arranged on the PCB, with the induction coil supplying power to the PCB chip. When the magnetic flux of the closed magnetic circuit of the second induction section 24 and the first induction section 14 changes, the induction coil electromagnetically couples with the closed magnetic circuit of both the second induction section 24 and the first induction section 14, thereby achieving inductive power extraction.

[0040] In some embodiments, the PCB board has a pre-installed interface for a temperature sensor that can interface with an external temperature sensor. In some embodiments, the temperature sensor is an NTC (Negative Temperature Coefficient) sensor, which is fixed in a metal tube with epoxy resin. The NTC leads are equipped with quick-connect terminals, allowing for quick connection to the pre-installed interface on the PCB. The metal tube encapsulating the NTC can be fixed to the surface of the busbar housing using dedicated clips.

[0041] In some embodiments, a ZigBee communication component is designed on the PCB to enable communication transmission with the gateway. The temperature measurement module is equipped with an external ZigBee antenna, which can increase the ZigBee signal strength and extend the transmission distance. It is worth noting that ZigBee wireless transmission is only an example of signal transmission; temperature signals can also be transmitted using other appropriate wireless protocols.

[0042] According to the sensing device of this disclosure, the power supply module is divided into a first sensing section 14 installed on the busbar device side or the conductor 30 side and a second sensing section 24 installed on the functional body 20 side. For example, one or more power access interfaces can be reserved at appropriate locations on the busbar device, and the functional body 20 can be installed to the power access interface when needed to conveniently realize conductor measurement.

[0043] The above solution offers the following advantages over existing technologies. It enables simplified installation and maintenance without requiring power outages to equipment in the power distribution network. Furthermore, prefabricating the power input interface on the busbar device reduces on-site installation time. Additionally, inductive power extraction offers high safety; specifically, compared to direct power extraction, inductive power extraction isolates the busbar and sensing device, reducing electrical risks from the busbar to the sensing device, such as insulation short circuits. Moreover, by drawing power from the busbar to supply power to the sensing device, it overcomes the limitations imposed by battery life.

[0044] Figures 3-4 Structural details of a sensing device for a busbar assembly according to an embodiment of this disclosure are shown. For example... Figures 3-4As shown, the first sensing section 14 includes a first magnetic yoke having a first end 142 and an opposite second end 144. The first end 142 and the second end 144 at least partially surround the conductor 30 and are adapted to form magnetic coupling with corresponding ends of the second sensing section 24, respectively. In some embodiments, the first sensing section 14 and the second sensing section 24 may be in direct contact to improve coupling efficiency. In other embodiments, the first sensing section 14 and the second sensing section 24 may be spaced apart from each other by a certain gap.

[0045] In some embodiments, such as Figures 3-4 As shown, the first magnetic yoke may be a single piece, and the first end 142 and the second end 144 may form an open loop surrounding one open end of the conductor 30. In some embodiments, the direction of the open loop of the first magnetic yoke may be perpendicular to the direction of the current flowing in the conductor 30, thereby facilitating electromagnetic induction. In some embodiments, the first magnetic yoke may be provided with an insulating layer so that the first magnetic yoke and the conductor 30 are electrically insulated from each other.

[0046] In some embodiments, the first magnetic yoke may be formed in a sheet shape and its thickness is less than the gap between two adjacent conductors 30. This structure is particularly convenient for arranging the first magnetic yoke, which occupies very little space. It is worth noting that the sheet-like structure of the first magnetic yoke is merely exemplary, and the first magnetic yoke can be formed in any other suitable form.

[0047] Similarly, the second induction section 24 may include a second magnetic yoke. The second magnetic yoke has a third end 242 and an opposite fourth end 244. The third end 242 and the fourth end 244 are adapted to contact the first end 142 and the second end 144, respectively, to form a magnetic flux loop. The second magnetic yoke may be formed in a sheet shape and is adapted to be electromagnetically coupled to the first magnetic yoke. It is worth noting that the sheet-like structure of the second magnetic yoke is merely exemplary, and the first magnetic yoke may be formed in any other suitable form.

[0048] In some embodiments, the conductor connector 12 may further include an opening and a separator 15 disposed in the opening, the separator 15 being located between the first end 142 and the second end 144. The separator 15, together with the first end 142 and the second end 144, defines insertion ports adapted to receive the third end 242 and the fourth end 244 of the second yoke, respectively. Thus, electromagnetic coupling between the first yoke and the second yoke can be conveniently achieved through a plug-in connection.

[0049] The first sensing section 14 and the second sensing section 24 may include various adaptable shapes, as long as reliable electromagnetic coupling between the first sensing section 14 and the second sensing section 24 can be achieved. Figures 3-5Details of the engagement of the first sensing segment 14 and the second sensing segment 24 according to an embodiment of the present disclosure are shown.

[0050] In some embodiments, such as Figures 3-5 As shown, the conductor connector 12 may include a base 16 and a first mating portion 18 disposed in the base 16. The base 16 may be fixed to the busbar assembly 100. Correspondingly, the functional body 20 includes a housing 26, and the main connector 22 includes a second mating portion 28 disposed on the housing 26, the second mating portion 28 being form-fitted with the first mating portion 18. Thus, the conductor connector 12 and the functional body 20 can be engaged with each other through the form-fitting of the first mating portion 18 and the second mating portion 28.

[0051] In some embodiments, such as Figures 3-5 As shown, the magnetic coupling ends (i.e., first end 142 and second end 144) of the first sensing section 14 are disposed on the outer surface of the first matching part 18, and the corresponding magnetic coupling ends (i.e., third end 242 and fourth end 244) of the second sensing section 24 are disposed on the outer surface of the second matching part 28. Thus, while the conductor connector 12 and the functional body 20 are engaged with each other, the first sensing section 14 and the second sensing section 24 are in contact with each other via the shape fit between the second matching part 28 and the first matching part 18 to form a magnetic flux loop.

[0052] In some embodiments, such as Figures 3-5 As shown, the first mating portion 18 may include an inclined opening, which may include a first inclined surface, and the magnetic coupling end of the first sensing segment 14 is at least partially disposed on the first inclined surface. Correspondingly, the second mating portion 28 includes an inclined protrusion, which includes a second inclined surface, and the magnetic coupling end of the second sensing segment 24 is at least partially disposed on the second inclined surface. It is worth noting that this is merely an example of form-fitting; the first mating portion 18 and the second mating portion 28 may include any other suitable shape, such as trapezoidal, conical, arc-shaped, or other shapes.

[0053] In some embodiments, such as Figures 3-5 As shown, the first matching portion 18 may further include a first vertical contact surface extending from the first inclined surface, and the magnetic coupling end of the first sensing segment 14 is at least partially disposed on the first vertical contact surface. The second matching portion 28 may include a second vertical contact surface extending from the inclined protrusion, and the magnetic coupling end of the second sensing segment 24 is at least partially disposed on the second vertical contact surface. In this case, by forming multiple coupling ends in the first matching portion 18 and the second matching portion 28, it can be ensured that the first sensing segment 14 and the second sensing segment 24 can always reliably contact each other to form a magnetic flux loop.

[0054] In some embodiments, such as Figures 3-5As shown, the base 16 may include a spacer 15. The spacer 15 extends between a first end 142 and a second end 144 of the first sensing section 14. In some embodiments, the spacer 15 may also physically interact at least partially with the housing 26 when the first mating portion 18 and the second mating portion 28 are in contact with each other. In some embodiments, such as Figure 5 As shown, housing 26 may include slot 25 at a position corresponding to separator 15. When first mating portion 18 and second mating portion 28 engage with each other to attach conductor connector 12 and functional body 20 to each other, separator 15 may engage with slot 25 to further ensure the installation reliability of first sensing section 14 and second sensing section 24 and prevent the first sensing section 14 and second sensing section 24 from accidentally disengaging from each other.

[0055] According to this disclosure, a bus system is also provided, including: a bus assembly 200; and at least one conductor joint 12 pre-formed at at least one location of the bus assembly, wherein the conductor joint is adapted to engage with a body joint (22) of a sensing device (100).

[0056] Furthermore, although the operations are described in a specific order, this should be understood as requiring that such operations be performed in the specific order shown or in sequential order, or requiring that all illustrated operations be performed to achieve the desired result. In certain environments, multitasking and parallel processing may be advantageous. Similarly, although several specific implementation details are included in the above discussion, these should not be construed as limiting the scope of this disclosure. Certain features described in the context of individual embodiments may also be implemented in combination in a single implementation. Conversely, various features described in the context of a single implementation may also be implemented individually or in any suitable sub-combination in multiple implementations.

Rather, the specific features and actions described above are merely illustrative examples of implementing the claims.

[0058] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
