Description

Technical Field

[0001] This application relates to the technical field of power terminal collectors, and particularly to a communication AC / DC power terminal collector. Background Art

[0002] With the rapid development of smart grid, 5G communication base stations and Internet of Things technologies, AC / DC hybrid power supply systems are increasingly widely used in fields such as industrial control, data centers, and new energy power stations. As the core component of the power monitoring system, the power terminal collector undertakes the key tasks of AC / DC power parameter acquisition, status monitoring, and data communication.

[0003] In practical applications, power terminal acquisition systems in different scenarios have different acquisition requirements. Generally, power terminal acquisition systems generally only monitor and analyze the total power supply of the power supply (mains input power supply) and the power conversion system (DC-side high-frequency switching power supply, AC-side UPS and its input and output power supplies, battery packs), that is, only the total power supply of the AC / DC distribution board at the equipment load side is monitored.

[0004] In some scenarios with high requirements for acquisition data, the power terminal acquisition system also needs to monitor the branch circuits of the branch distribution cabinets at the lower level of the AC / DC distribution board on the load side of communication equipment and the power data of the DC air switches and AC PDUs of the equipment loads in the end cabinets. In this case, in order to meet the data acquisition requirements, it is necessary to transform the power terminal data acquisition system.

[0005] The existing power terminal collectors obtain circuit parameters by directly connecting in series or in parallel.

[0082] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a replaceable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be directly connected or indirectly connected through an intermediate medium. It can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0083] Please refer to Figures 1 to 3, in the embodiment of the present application, a communication AC / DC power terminal collector is provided, including: a collection device 2; the collection device 2 includes: a non-invasive sensing component, a mounting bracket 21 and a wire fixing mechanism 25; the wire fixing mechanism 25 includes: a mounting shell 2501, a snap ring 2502 and a wire fixing screw 2509; the mounting shell 2501 is arranged on the mounting bracket 21; the snap ring 2502 is arranged on the mounting shell 2501 so as to be movable in the vertical direction; the snap ring 2502 and the mounting shell 2501 enclose a wire loading cavity for mounting a wire; the wire fixing screw 2509 is threadedly connected to the mounting shell 2501; when the wire fixing screw 2509 rotates, it can drive the snap ring 2502 to move in the vertical direction to adjust the size of the wire loading cavity; the non-invasive sensing component is arranged on the mounting bracket 21 and is used for measuring data of the wire without damaging the wire.

[0084] In this solution, the non-invasive sensing component can collect data such as current and voltage of the wire without damaging the wire. Specifically, the non-invasive sensing component can be set to contact the wire without damaging the outside of the wire; after adopting this solution, during transformation and maintenance, the disassembled components do not involve the wire, so that the transformation and maintenance operations can be realized without power interruption. Specifically, during transformation and maintenance, removing the collection device 2 can not affect the operation of the wire itself, thereby reducing the workload of transformation and eliminating the need for power interruption.

[0085] Moreover, during actual application, when the installation position of the collection device 2 is changed due to reasons such as the collection object and the requirements for collected data, the wire diameters of the wires at different positions are not equal. In this solution, the wire fixing mechanism 25 can fix wires with different diameters through the wire loading cavity with adjustable size, thereby reducing the wiring difficulty, reducing the transformation cost and improving the transformation efficiency. Specifically, when the wire fixing screw 2509 rotates, it can drive the snap ring 2502 to move in the vertical direction, thereby realizing the adjustment of the size of the wire loading cavity.

[0086] In a more specific embodiment, the wire fixing mechanism 25 includes: a first slider 2504, a second slider 2506 and a tension spring 2505; a limiting groove 2503 is provided on the upper part of the mounting shell 2501; the first slider 2504 and the second slider 2506 are arranged in the limiting groove 2503 so as to be slidable in the vertical direction; the tension spring 2505 is located between the first slider 2504 and the second slider 2506, and the two ends are respectively connected to the first slider 2504 and the second slider 2506; the second slider 2506 and the first slider 2504 are distributed vertically; the top end of the wire fixing screw 2509 is rotatably connected to the first slider 2504; the snap ring 2502 is connected to the second slider 2506.

[0087] In this embodiment, when the wire-fixing screw 2509 rotates, it can move up and down along the mounting shell 2501 and drive the first slider 2504 to move up and down. When the first slider 2504 moves up and down, it drives the second slider 2506 to move up and down through the tension spring 2505, so as to adjust the size of the wire-loading cavity. Among them, pulling the snap ring 2502 downward through the tension spring 2505 can play a buffering role for the wire below the snap ring 2502, and avoid damaging the wire due to the snap ring 2502 being installed too tightly.

[0088] As an implementation manner, a plurality of limiting grooves 2503 can be provided on the mounting shell 2501, and the first slider 2504 and the second slider 2506 are simultaneously placed in the plurality of limiting grooves 2503 to ensure the stability of their sliding.

[0090] As an implementation manner, the way that the snap ring 2502 is connected to the second slider 2506 can be, for example, to provide a locking tongue 2508 on the snap ring 2502 and a snap buckle 2507 on the second slider 2506; the locking tongue 2508 is detachably snapped into the snap buckle 2507 and is snap-connected to the snap buckle 2507.

[0093] As an implementation manner, an infrared temperature sensor 210 is fixedly installed on the top of the first mounting bracket 21 to monitor the temperature of the current-carrying wire in real time through the infrared temperature sensor 210; when the wire temperature is abnormal, commands such as power-off or load reduction are sent to the power supply system through the following terminal device 1 to avoid fires or other dangers.

Finally, the wire between the two groups of wire fixing mechanisms 25 is straightened to prevent the acquisition device 2 from loosening on the outer wall of the wire.

[0100] It should be noted that in this embodiment, the two adjusting blocks 2405 are respectively disposed on both sides of the mounting block 2402 to ensure that when the mounting block 2402 slides, the two adjusting blocks 2405 move in opposite directions.

[0102] Through the rotating frame 2602, during the modification, the staff can release the clamping connection between the rotating frame 2602 and the fixed frame 2601, and then drive the rotating frame 2602 to rotate, so as to separate the non-invasive sensor component from the wire.
