Description

Technical Field

[0001] This utility model relates to the field of power status monitoring technology, specifically a sensor deployment device for 10kV dual power supply supervision based on ubiquitous sensing technology. Background Technology

[0002] 10kV dual power supply is a widely used power supply configuration in power systems. This power supply usually comes from different substations or different busbars of the same substation to ensure the independence and reliability of the power supply. Under this power supply condition, the management of the power supply is particularly important. Ubiquitous sensing technology is an emerging technology that uses various sensing devices and technical means to achieve comprehensive, real-time and dynamic sensing of the target location, which is very beneficial for the effective monitoring of the working status of dual power supply.

[0003] When monitoring using ubiquitous sensing technology, multiple sensors are usually required to detect data such as current and voltage. Existing detection methods typically involve installing sensors specifically for the data to be detected. However, this approach cannot achieve unified management and output. The data from two power supply circuits need to be viewed and compared separately. Furthermore, for dual power supplies, it is difficult to determine the relative fluctuations between the two power supplies, which is quite inconvenient. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a 10kV dual-power supply monitoring sensor deployment device based on ubiquitous sensing technology. It has the advantages of being able to conveniently monitor various parameters simultaneously and work collaboratively. It solves the problems of existing detection methods being unable to achieve unified management and unified output, requiring separate viewing and comparison of data from the two power supply circuits, and making it inconvenient to determine the relative fluctuations of the two power supplies for dual power supplies.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A sensor deployment device for 10kV dual power supply supervision based on ubiquitous sensing technology includes a C-shaped parallel bracket. An adjustable current sensor connection bracket is provided on the outside of the parallel bracket. An integrated controller for processing sensor data and wireless transmission is provided on the outside of the parallel bracket. An infrared temperature sensor facing the power supply direction is provided on the outside of the integrated controller. A partial discharge sensor connection frame that can be flexibly bent and connected by a connector is provided on the outside of the integrated controller. A signal transmission bridge that can be connected end to end is provided on the outside of the integrated controller.

[0008] The two ends of the parallel bracket are connected to the power supply input terminal and the load input terminal through wiring terminals. The wiring terminals of the parallel bracket are connected to the integrated controller through wires.

[0009] A position adjustment component is provided between the parallel support and the current sensor connection support, and the position is adjusted through the component.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the integrated controller integrates sensor data to generate control signals and output signals, and the integrated controller is externally equipped with a control signal output connector.

[0012] Furthermore, the integrated controller also includes a calibration module, which performs sensor signal calibration when two or more integrated controllers are connected through a signal transmission bridge.

[0013] Furthermore, an ultrasonic sensor-type partial discharge sensor is connected to the end of the partial discharge sensor connector.

[0014] Furthermore, the position adjustment component includes a sliding sleeve that is slidably connected to the parallel bracket and connected to the current sensor connection bracket. The sliding sleeve has a signal transmission frame that is slidably connected to the parallel bracket and forms a snap-fit ​​connection. The inner wall of the signal transmission frame is provided with an elastic element that is connected to the sliding sleeve. The end of the signal transmission frame is provided with a limiting lever that contacts the parallel bracket.

[0015] Furthermore, the outer side of the sliding sleeve is provided with a contact point that is connected to the integrated controller via a wire and extends to its inner side, and the end of the signal transmission frame is provided with an elastic compression contact that is connected to the current sensor connection bracket and whose other end abuts against the contact point.

[0016] This invention provides a sensor deployment device for 10kV dual power supply monitoring based on ubiquitous sensing technology. By setting up parallel brackets, the device can be connected to monitor the voltage during power supply operation. Simultaneously, a current sensor can be deployed via a current sensor connection bracket to detect the power supply current. After connecting a partial discharge sensor via a partial discharge sensor connection bracket, the partial discharge status can be monitored. Combined with an infrared temperature sensor, multiple attributes of the power supply can be monitored. Furthermore, for dual power supply monitoring, multiple sensors need to be deployed through two deployment devices. In this case, the two deployment devices can be connected via a signal transmission bridge. By comparing the signals from both devices, the fluctuation status of the detection information and accurate partial discharge information can be determined. Moreover, when multiple partial discharge sensors are present, because they are located using ultrasonic waves, the location of abnormal partial discharges can be determined more accurately under dual positioning.

[0017] In summary, this 10kV dual-power supply monitoring sensor deployment device based on ubiquitous sensing technology has the advantage of being able to conveniently monitor various monitoring parameters simultaneously and work collaboratively. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a 10kV dual power supply monitoring sensor deployment device based on ubiquitous sensing technology, including a C-shaped parallel bracket 1, an adjustable current sensor connection bracket 2 on the outside of the parallel bracket 1, an integrated controller 3 for processing and wirelessly transmitting sensor data on the outside of the parallel bracket 1, an infrared temperature sensor 4 facing the power supply direction on the outside of the integrated controller 3, a partial discharge sensor connection bracket 5 connected by a connector and capable of flexible bending on the outside of the integrated controller 3, and a signal transmission bridge 6 that can be connected end to end on the outside of the integrated controller 3.

[0026] The two ends of the parallel bracket 1 are connected to the power supply input terminal and the load input terminal through wiring terminals. The wiring terminals of the parallel bracket 1 are connected to the integrated controller 3 through wires.

[0027] A position adjustment component 7 is provided between the connection point of the parallel bracket 1 and the current sensor connection bracket 2, and the position is adjusted through it.

[0028] In particular, during the deployment of this device, an open-loop Hall current sensor can be selected as the current sensor. This type of sensor is easy to connect and can easily detect the surrounding cables.

[0029] The integrated controller 3 integrates sensor data to generate control signals and output signals, and the integrated controller 3 is externally equipped with a control signal output connector.

[0030] The integrated controller 3 also includes a calibration module, which performs sensor signal calibration when two or more integrated controllers 3 are connected through a signal transmission bridge 6.

[0031] Among them, an ultrasonic sensor-type partial discharge sensor is connected to the end of the partial discharge sensor connector 5.

[0032] In particular, when there are multiple deployment devices, the multiple partial discharge sensors should be arranged in an array. This arrangement facilitates coordinate establishment and forms a more accurate directional guide based on the signal strength and direction detected by each partial discharge sensor, which can facilitate the confirmation of the partial discharge location.

[0033] If only a single partial discharge sensor exists, although it can determine the direction of the partial discharge, the degree of discharge and the specific location of the discharge are often impossible to determine. For monitoring of dual power supplies, at least two deployment devices need to be connected, that is, two partial discharge sensors are used in conjunction with the signal transmission bridge 6 for comparative monitoring, so as to conveniently determine the specific location and intensity of the partial discharge.

[0034] The position adjustment component 7 includes a sliding sleeve 71 that is slidably connected to the parallel bracket 1 and connected to the current sensor connection bracket 2. The inside of the sliding sleeve 71 is slidably connected to a signal transmission frame 72 that forms a snap-fit ​​with the parallel bracket 1. The inner wall of the signal transmission frame 72 is provided with an elastic element 73 that is connected to the sliding sleeve 71. The end of the signal transmission frame 72 is provided with a limiting lever 74 that contacts the parallel bracket 1.

[0035] The sliding sleeve 71 has a contact point on its outside that is connected to the integrated controller 3 by a wire and extends to its inside. The signal transmission frame 72 has an elastic compression contact at its end that is connected to the current sensor connection bracket 2 and abuts against the contact point at its other end.

[0036] Specifically, while the elastic force of the elastic element 73 pushes the limiting paddle 74 to contact the parallel bracket 1 to form sliding damping, it can press the elastic compression contact into contact with the contact contact.

[0037] By setting the position adjustment component 7, when the current detection sensor is connected to the current sensor connection bracket 2, the limiting lever 74 can be moved to prevent it from pressing against the parallel bracket 1, and at the same time, the contact point is disconnected from the pressing contact. At this time, the sliding sleeve 71 can be pushed directly to slide it, thereby adjusting the position of the current sensor connection bracket 2. The position of the current sensor can be adjusted to adapt to various cable bending conditions and cable sizes.
