Description

Technical Field

[0001] This utility model relates to the field of copper busbar voltage measurement sensor technology, and in particular to a copper busbar voltage measurement sensor. Background Technology

[0002] By monitoring the voltage signal of the power supply line online, the power supply status of the line can be monitored, thereby obtaining the line's operating status and fault analysis. Generally, the voltage signal of the line is obtained by installing clamp sensors on the line, and then uploaded to the platform for analysis, allowing back-end personnel to monitor the line's status in real time.

[0003] Existing sensors are integrated structures that combine power acquisition and measurement, and are used for monitoring wire-type power supply lines. For transmission lines with different widths, such as copper busbars, the sensors need to be replaced according to the different widths of the copper busbars. If the existing integrated structure is designed, a sensor needs to be matched to each type of copper busbar width, resulting in poor versatility and high cost. Utility Model Content

[0004] The purpose of this invention is to provide a copper busbar voltage measurement sensor that adopts a split design structure to be clamped and installed on copper busbars of different widths, thereby improving versatility and reducing costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A copper busbar voltage measurement sensor includes a data acquisition unit and a transceiver unit. The data acquisition unit includes a clamping housing and rotating shafts located at both ends of the clamping housing. A clamping block is rotatably mounted on the rotating shaft, and a torsion spring is sleeved on the rotating shaft to drive the clamping block to rotate inward. An integrated housing is detachably mounted on the clamping housing. A voltage measurement chip, a first circuit board, and a first socket are installed inside the integrated housing. The voltage measurement chip, the first socket, and the first circuit board are electrically connected. The transceiver unit includes a lower housing and an upper housing mounted on the lower housing. An upper magnetic ring, a second circuit board, and a second socket are installed inside the upper housing. A lower magnetic ring is installed inside the lower housing. The upper magnetic ring, the lower magnetic ring, the second socket, and the second circuit board are electrically connected. The first socket and the second socket are connected by a wire. Copper busbar clamping holes are provided on both sides of the upper and lower housings. Elastic clamping structures for clamping copper busbars are provided in the copper busbar clamping holes.

[0007] Preferably, the elastic clamping structure includes clamping sliders that are slidably mounted on both sides of the upper and lower housings, and each clamping slider is provided with a plurality of springs evenly distributed along the length direction.

[0008] Preferably, the pressing slider is embedded with anti-slip rubber.

[0009] Preferably, one end of the upper housing is rotatably mounted on the lower housing, the other end of the upper housing is provided with a locking sleeve, and the lower housing is provided with a locking post coaxial with the locking sleeve. Fasteners pass through the locking sleeve and are locked on the locking post.

[0010] Preferably, a protective shell is detachably mounted on the upper housing, and the protective shell and the upper housing together form a mounting cavity, in which the second circuit board is mounted.

[0011] Preferably, both the upper housing and the lower housing are snap-fitted together with limiting plates.

[0012] Preferably, an indicator light connected to the first circuit board is mounted on the integrated housing.

[0013] Preferably, the inner surface of the clamping block is provided with a plurality of anti-slip protrusions.

[0014] Beneficial effects:

[0015] The acquisition unit and the transceiver unit are designed as separate structures. In the acquisition unit, the clamping block on the clamping housing is driven by a torsion spring to rotate inward and clamp onto the copper busbar. When measuring copper busbars with different widths, the clamping housing can be replaced. The integrated housing and its internal voltage measurement chip, first circuit board, etc. do not need to be replaced. Therefore, multiple clamping housings need to be designed to adapt to the width of the copper busbar, which can effectively control the replacement cost of the acquisition unit.

[0016] The transceiver unit draws power from the copper busbar and transmits information remotely. It can draw power through the copper busbar and is also versatile. The transceiver unit integrates an upper magnetic ring and a lower magnetic ring, which are fitted onto the copper busbar to draw power from the second circuit board. The second circuit board receives the voltage signal from the voltage measurement chip obtained by the first circuit board through the second socket, wires, and the first socket and transmits it outward. At the same time, it conducts electricity to the first circuit board through the wires.

[0017] After the transceiver unit passes through the copper busbar clamping hole, it is positioned on the copper busbar using an elastic clamping structure to keep it near the acquisition unit, which is sufficient to meet the wire connection length requirements.

[0018] Therefore, by adopting a split structure, the core voltage detection and signal transceiver parts can be made universal, and only the acquisition unit needs to be adapted to clamping different copper busbar widths, which effectively reduces costs and improves versatility.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] See Figures 1-6 As shown in the figure, an embodiment of this utility model proposes a copper busbar voltage measurement sensor, including a data acquisition unit 1 and a transceiver unit 2. The data acquisition unit 1 and the transceiver unit 2 are separate structures. The relevant principles for data acquisition and transmission are based on the technical principles of existing measurement sensors. However, existing technologies are generally integrated structures, requiring tight clamping to ensure measurement accuracy when clamping the copper busbar for measurement. Since copper busbars have different widths, replacing the entire measurement sensor is costly. The separate structure achieves versatility and reduces costs.

[0029] Specifically, the acquisition unit 1 includes a clamping housing 101 and rotating shafts 102 located at both ends of the clamping housing 101. Clamping blocks 103 are rotatably mounted on the rotating shafts 102. Torsion springs 104 are sleeved on the rotating shafts 102 to drive the clamping blocks 103 to rotate inward. When clamped onto the copper busbar, the clamping blocks 103 are pushed to rotate inward by the force of the torsion springs 104, thereby clamping the clamping blocks 103 at both ends onto the copper busbar, and stably clamping and fixing the entire clamping housing 101 onto the copper busbar. Specifically, an integrated housing 105 is detachably mounted on the clamping housing 101. The integrated housing 105 houses a voltage measurement chip 106, a first circuit board 107, and a first socket 108. The voltage measurement chip 106, the first socket 108, and the first circuit board 107 are electrically connected. The first circuit board 107 is a circuit board with an integrated processor, used to collect the voltage signal acquired by the voltage measurement chip 106, process it, and then transmit it externally through the first socket 108. After integrating the voltage measurement chip 106, the first circuit, and the first socket 108 into the integrated housing 105, the clamping housing 101 can be disassembled to match different clamping widths, allowing the core measurement components to be used without disassembly or replacement. Furthermore, replacing the clamping housing 101 ensures secure clamping on the corresponding copper busbar. The measurement circuit and data transmission circuit implemented by the first circuit board 107, the voltage measurement chip 106, and the first socket 108 all utilize existing mature technologies.

[0030] The transceiver unit 2 is initially positioned on the copper busbar independently of the acquisition unit 1, and transmits the output signal of the acquisition unit 1 outward. Specifically, the transceiver unit 2 includes a lower housing 21 and an upper housing 22 mounted on the lower housing 21. The upper housing 22 houses an upper magnetic ring 23, a second circuit board 24, and a second socket 25. The lower housing 21 houses a lower magnetic ring 26. The upper magnetic ring 23, the lower magnetic ring 26, the second socket 25, and the second circuit board 24 are electrically connected. The first socket 108 and the second socket 25 are connected by wires. The integrated upper magnetic ring 23 and lower magnetic ring 26 generate electromagnetic induction after passing through the copper busbar, generating power to supply power to the second circuit board 24 and simultaneously supply power to the first circuit board 107 via wires. The second circuit board 24 also receives the voltage signal processed by the first circuit board 107 and transmits it outward. The specific circuit principle is consistent with existing technology.

[0031] Specifically, copper busbar clamping holes 27 are provided on both sides of the upper housing 22 and the lower housing 21. The copper busbar clamping holes 27 are provided with elastic clamping structures 28 for clamping the copper busbar. The copper busbar clamping holes 27 facilitate the passage of the copper busbar, while the elastic clamping structures 28 clamp the copper busbar on both sides, so that the transceiver unit 2 is clamped and fixed on the copper busbar. For the transceiver unit 2, it is sufficient to stop relative to the acquisition unit 1, mainly to prevent the wires from falling off.

[0032] The elastic clamping structure 28 includes pressing sliders 281 that are slidably mounted on both sides of the upper housing 22 and the lower housing 21. Each pressing slider 281 is provided with a plurality of springs 282 evenly distributed along the length direction. The pressing slider 281 is pressed against the copper busbar by the action of the springs 282.

[0033] To ensure sliding after clamping, anti-slip rubber 283 is embedded in the clamping slider 281.

[0034] Specifically, the transceiver unit 2 requires the upper housing 22 to be separated from the lower housing 21 to facilitate the insertion and clamping of the copper busbar. One end of the upper housing 22 is rotatably mounted on the lower housing 21, and the other end of the upper housing 22 is provided with a locking sleeve 29. The lower housing 21 is provided with a locking post 210 coaxial with the locking sleeve 29. Fasteners pass through the locking sleeve 29 and are locked on the locking post 210. The fasteners realize the locking or loosening between the upper housing 22 and the lower housing 21, which facilitates the rotation of the upper housing 22 relative to the lower housing 21 to open or close, and makes it convenient to insert the copper busbar between the upper housing 22 and the lower housing 21.

[0035] Meanwhile, the second circuit board 24 is isolated and mounted on the upper housing 22 to facilitate maintenance without disassembling the internal parts. Specifically, a protective shell 211 is detachably mounted on the upper housing 22. The protective shell 211 and the upper housing 22 enclose a mounting cavity 212, in which the second circuit board 24 is mounted. The second circuit board 24 can be easily assembled and maintained by removing the protective shell 211 relative to the upper housing 22.

[0036] Meanwhile, a limiting plate 213 is snapped into both the upper housing 22 and the lower housing 21. The limiting plate 213, which is snapped into place, facilitates the installation and positioning of the upper magnetic ring 23 and the lower magnetic ring 26.

[0037] Specifically, an indicator light 109 connected to the first circuit board 107 is installed on the integrated housing 105 to indicate whether the acquisition unit 1 is in operation.

[0038] Meanwhile, in order to ensure that the clamping housing 101 will not slide after being clamped on the copper busbar by the clamping block 103, a number of anti-slip protrusions 1010 are arranged in an array on the inner side of the clamping block 103. The anti-slip protrusions 1010 increase the friction and prevent relative sliding.
