Description

Technical Field

[0001] The present invention relates to the technical field of power monitoring, and specifically to a load monitoring device for a power distribution network. Background Art

[0002] The power load, also known as the "electrical load", refers to the total electric power consumed by the electrical equipment of electricity users from the power system at a certain moment. In a distribution network, monitoring devices are often used to monitor the operating load of the power grid to ensure the stable operation of the power grid.

[0003] For example, a load monitoring device integrating sampling and power supply energy extraction and its control method disclosed in Chinese Patent CN202110478061.9. It can be known that this load monitoring device integrating sampling and power supply energy extraction and its control method ensure the accuracy of load data on the line through a high-precision and high-sampling-rate acquisition circuit. At the same time, the method of synchronous sampling using a Rogowski coil and a current transformer ensures that the range of sampled data is sufficient, and ensures the safety of the device and the accuracy of sampled data during overload and surge, effectively compensating for the defects of magnetic saturation and hysteresis existing in the current transformer itself, and realizing seamless switching between standby power supply energy extraction and current data acquisition by adopting the PWM pulse width modulation method.

[0004] And a portable three-phase power load monitor disclosed in Chinese Patent CN201810602782.4. It can be known that it includes: a first communication unit for communicating with a second communication unit in a dedicated transformer acquisition terminal; a current detection unit for detecting the load current of the secondary circuit of the current transformer; a signal application unit for injecting a high-frequency voltage signal into the secondary circuit of the current transformer; a resonance unit that resonates when a high-frequency voltage signal is injected into the secondary circuit of the current transformer; an inverter that forms a self-excited oscillation circuit with the resonance unit; and a micro-control unit for realizing data acquisition, process control, and signal control. The current transformer secondary circuit monitoring module, method, and dedicated transformer acquisition terminal provided by this invention realize the state monitoring of the normal connection, open circuit, short circuit, and short-circuited energy meter of the current transformer secondary circuit based on the impedance characteristics of the secondary circuit of the transformer.

[0005] In view of the retrieval of the prior art, it can be known that during use, it is usually necessary to manually operate the device, place the wire between two groups of current transformers for monitoring, and then the staff manually twist the clamping member to achieve positioning and clamping fixation of the current transformer and the wire, and then conduct monitoring, resulting in low monitoring operation efficiency. In addition, in the existing power distribution network load monitoring device, during monitoring, the current transformer is generally directly in contact with the wire, and the wire is monitored through the current transformer. However, dust is easily adsorbed on the surface of the wire, which will cause dust to exist between the current transformer and the wire during the monitoring process, thus affecting the monitoring effect and accuracy.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1:

[0020] Please refer to Figures 1 to 5This embodiment provides a technical solution: a power distribution network load monitoring device, including: a base 1, a cleaning mechanism, and two sets of mutual inductors 2.

[0021] More specifically, in this embodiment: dust on the surface of the wire is removed by a cleaning mechanism, and then two sets of mutual inductors 2 are brought into contact with the cleaned surface of the wire, and the load of the power distribution network is monitored through the mutual inductors 2.

[0022] It is worth noting that this embodiment also includes: a moving mechanism, a shaking dust removal mechanism, a clamping mechanism and a transmission assembly.

[0023] More specifically, in this embodiment: first, the base 1 is placed at the lower end of the wire, the wire is inserted into the cleaning mechanism, and the cleaning mechanism is driven to move laterally by the moving mechanism, so that the cleaning mechanism moves from one side of the base 1 to the inside of the base 1, and then moves to the other side of the base 1, that is, the cleaning mechanism moves laterally along the outer surface of the wire, and the dust on the outer surface of the wire is removed by the cleaning mechanism, so that the wire monitoring part is kept clean, and the dust is prevented from affecting the monitoring effect and accuracy; when the cleaning mechanism is about to move from the base 1 to the other side of the base 1, the clamping mechanism is driven to work through the action of the transmission component, so that the clamping mechanism is retracted and clamped on the outer surface of the wire, so that the mutual inductor 2 is in contact with the outer surface of the wire, and the mutual inductor 2 is used to remove the dust from the outer surface of the wire. The sensor 2 monitors the load of the power distribution network and can automatically clamp and measure the wires without manual clamping. The method of cleaning and dust removal before clamping and measuring is adopted, and the cleaning mechanism and the clamping mechanism are linked to improve the monitoring operation efficiency. There is no need for manual cleaning and clamping monitoring, which reduces the labor intensity. When the cleaning mechanism moves to the other end of the base 1, the mutual inductor 2 monitors the wires. The dust adhering to the cleaning mechanism and cleaned from the surface of the wires are shaken and dusted by the dust removal mechanism, so that the cleaning mechanism can automatically remove dust, ensuring the effect of cleaning the dust on the wires when it is used next time. There is no need for manual dust removal operation, which reduces the labor intensity of workers. Embodiment 2:

[0024] Based on the above embodiment: See also Figure 1 、 Figure 2 and Figure 3 The cleaning mechanism in the first embodiment is disclosed as follows. The cleaning mechanism includes: The support seat 3 has an open groove on the upper end thereof, a fixed shaft 4 is fixed in the open groove, a first cleaning plate 5 and a second cleaning plate 6 are rotatably provided on the outer surface of the fixed shaft 4, the first cleaning plate 5 and the second cleaning plate 6 are both arc-shaped, a sponge brush 7 is fixed on the inner surface of the first cleaning plate 5 and the second cleaning plate 6, a torsion spring 8 is connected between the first cleaning plate 5 and the second cleaning plate 6 and located on the outer surface of the fixed shaft 4, and a connecting plate 9 is fixed on the front side of the support seat 3.

[0025] More specifically, in this embodiment: when performing monitoring installation, the staff will place the base 1 at the lower end of the wire, and pry the first cleaning plate 5 and the second cleaning plate 6 apart to both sides, so that the first cleaning plate 5 and the second cleaning plate 6 swing outward with the fixed axis 4 as the center. At this time, the torsion spring 8 is deformed by the force, and then the wire is passed through the first cleaning plate 5 and the second cleaning plate 6. Then, the first cleaning plate 5 and the second cleaning plate 6 are loosened, so that the torsion spring 8 loses its force and rebounds, and the first cleaning plate 5 and the second cleaning plate 6 swing inward and reset, so that the sponge brushes 7 on the inner surfaces of the first cleaning plate 5 and the second cleaning plate 6 come into contact with the outer surface of the wire, and the dust on the outer surface of the wire can be brushed off by the sponge brush 7; When the monitoring is completed and the power distribution network load monitoring device needs to be removed from the wires, after the cleaning mechanism is reset under the drive of the driving mechanism, the first cleaning plate 5 and the second cleaning plate 6 are opened outwards, and the power distribution network load monitoring device is moved downward so that the cleaning mechanism is separated from the wires.

[0026] The upper ends of the left and right side walls of the base 1 are each provided with an avoidance groove 10 , which is adapted to the cleaning mechanism.

[0027] More specifically, in this embodiment: the setting of the avoidance groove 10 ensures that the left and right side walls of the base 1 will not hinder the left and right movement of the cleaning mechanism, so that the cleaning mechanism can move from one side of the base 1 to the inside of the base 1, and then move to the other end of the base 1, and also enable the cleaning mechanism to return from the other side of the base 1 to the inside of the base 1, and then return to one end of the base 1. Example 3:

[0028] Based on the above embodiment: See also Figure 1 、 Figure 2 and Figure 4 The mobile mechanism in the first embodiment is disclosed as follows. The mobile mechanism includes: Two groups of connecting frames 11 are respectively fixed on the left and right side walls outside the base 1. A first threaded rod 12 is rotatably provided between the two groups of connecting frames 11 through a bearing. A first motor 13 is fixedly installed on the outer wall of the connecting frame 11. The output shaft of the first motor 13 is fixedly connected to the end of the first threaded rod 12. The connecting plate 9 is threadedly connected to the first threaded rod 12. A guide light rod 14 is fixed between the two groups of connecting frames 11. A guide hole for the guide light rod 14 to pass through is opened on the connecting plate 9.

[0029] More specifically, in this embodiment: when the monitoring installation is performed, the first motor 13 is operated to drive the first threaded rod 12 to rotate, and the guide light rod 14 guides the connecting plate 9 of the cleaning mechanism, so that the connecting plate 9 of the cleaning mechanism can only move laterally and will not rotate with the first threaded rod 12. Therefore, the first threaded rod 12 rotates, driving the connecting plate 9 of the cleaning mechanism to move laterally under the guidance of the guide light rod 14, thereby causing the cleaning mechanism to move laterally from one side of the base 1 to the inside of the base 1, and then to the other side of the base 1, thereby causing the cleaning mechanism to move laterally along the outer surface of the wire, and the dust on the outer surface of the wire is removed by the cleaning mechanism; When the power distribution network load monitoring device needs to be removed from the wires after the monitoring is completed, the first motor 13 is reversed to drive the first threaded rod 12 to reverse, so that the cleaning mechanism moves in the opposite direction, from the other side of the base 1 to the inside of the base 1, and then moves back to the side of the base 1, thereby resetting the cleaning mechanism to facilitate the next operation. Embodiment 4:

[0030] Based on the above embodiment: See also Figure 1 and Figure 2 The shaking dust removal mechanism in the first embodiment is disclosed as follows. The shaking dust removal mechanism includes: The support frame 15 is fixed to the side wall of the base 1, and a second motor 16 is fixedly installed on the upper wall of the support frame 15. The output shaft of the second motor 16 is fixedly provided with a first rotating shaft 17, and a driving pulley 18 is fixedly provided on the outer surface of the first rotating shaft 17. A second rotating shaft 19 is rotatably provided on the side wall of the support frame 15 through a bearing, and a driven pulley 20 is fixedly provided on the outer surface of the second rotating shaft 19. The driven pulley 20 is connected to the driving pulley 18 through a belt 21, and a cam 22 is fixedly provided on the outer surface of the second rotating shaft 19; The first transmission plate 23 and the second transmission plate 24 are located on the side walls of the first cleaning plate 5 and the second cleaning plate 6 respectively.

[0031] More specifically, in this embodiment: When the second motor 16 operates, it drives the first rotating shaft 17 to rotate, driving the driving pulley 18 to rotate. Through the transmission of the belt 21, it drives the driven pulley 20 to rotate, thereby driving the second rotating shaft 19 to rotate. The rotation of the second rotating shaft 19 drives the cam 22 to rotate. During the rotation of the cam 22, it continuously extrudes the first transmission plate 23 connected to the first dust cleaning plate 5 of the cleaning mechanism or the second transmission plate 24 connected to the second dust cleaning plate 6 of the cleaning mechanism outward, causing the first dust cleaning plate 5 and the second dust cleaning plate 6 to continuously swing outward. At the same time, through the deformation and automatic reset function of the torsion spring 8 of the cleaning mechanism, the first dust cleaning plate 5 and the second dust cleaning plate 6 continuously reset inward. During this process, the first dust cleaning plate 5 and the second dust cleaning plate 6 continuously shake, thereby shaking off the dust on the sponge brush 7, enabling the sponge brush 7 to automatically remove dust and facilitating the next operation. Embodiment 5:

[0032] Based on the above embodiment: Please refer to Figure 1 and Figure 2 , the clamping mechanism in Embodiment 1 is publicly disclosed as follows. The clamping mechanism includes: Two groups of connecting shafts 25 are arranged up and down. The left and right ends of the connecting shaft 25 are respectively rotatably connected to the left and right side walls of the base 1 through bearings. A clamping plate 26 is fixedly provided on the outer surface of the connecting shaft 25. The clamping plate 26 is arc-shaped. First gears 27 are fixedly provided on both the left and right sides of the outer surface of the connecting shaft 25 where the clamping plate 26 is located. Two groups of the upper and lower corresponding first gears 27 are meshed and connected.

[0033] More specifically, in this embodiment: When monitoring and installing, under the action of the transmission component, one group of the connecting shafts 25 rotates, causing one group of the clamping plates 26 connected thereto to rotate, and driving the first gear 27 provided on its outer surface to rotate. Since the two groups of first gears 27 are meshed and connected, the first gear 27 provided on the outer surface of the other group of connecting shafts 25 rotates in the opposite direction to one group of the first gears 27, thereby causing the other group of connecting shafts 25 to rotate in the opposite direction to one group of the connecting shafts 25, driving the other group of the clamping plates 26 connected to the other group of connecting shafts 25 to rotate in the opposite direction to one group of the clamping plates 26, and further causing the two groups of clamping plates 26 to approach each other, so that the two groups of clamping plates 26 clamp the outer surface of the wire after dust cleaning; When it is necessary to remove the power distribution network load monitoring device from the wire after the monitoring is completed, under the reverse action of the transmission component, one group of the connecting shafts 25 rotates in the opposite direction, causing the two groups of clamping plates 26 to move away from each other, so that the two groups of clamping plates 26 open and disengage from the wire.

[0034] Two sets of mutual inductors 2 are respectively located on the inner surfaces of two sets of clamping plates 26. The mutual inductor 2 is connected to the control board, and the control board is connected to the main control machine.

[0035] More specifically, in this embodiment: After the clamping plate 26 clamps the outer surface of the wire, the two sets of mutual inductors 2 are in contact with the outer surface of the wire. The iron core coil in the mutual inductor 2 has the functions of energy extraction and measurement. The wire in use is monitored through the mutual inductor 2. The iron core coil in the mutual inductor 2 is connected to the control board through a wire, and the control board is wirelessly communicatively connected to the main control machine. The mutual inductor 2 transmits the monitored signal to the control board, and the control board then transmits the signal to the main control machine, which is convenient for the staff to view and make decisions. Embodiment 6:

[0036] Based on the above embodiment: Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , and the transmission assembly in the first embodiment is disclosed as follows. The transmission assembly includes: A support plate 28 is fixedly provided on the outer side wall of the base 1. The upper end of the support plate 28 is rotatably provided with a third rotating shaft 29 through a bearing. A driven bevel gear 30 is fixedly provided on the upper surface of the outer surface of the third rotating shaft 29. A driving bevel gear 31 meshing with the driven bevel gear 30 is fixedly provided on the outer surface of the connecting shaft 25. A second gear 32 is fixedly provided on the outer surface of the third rotating shaft 29; A rack 33 is fixedly provided on the front wall of the support seat 3 through a connecting block. The rack 33 and the second gear 32 are on the same horizontal plane. When the rack 33 moves to the position of the second gear 32, the rack 33 is meshed and connected with the second gear 32.

[0037] More specifically, in this embodiment: When performing monitoring and installation, when the cleaning mechanism is about to move from the base 1 to the other side of the base 1, the rack 33 connected to the cleaning mechanism will move to the position of the second gear 32 following the cleaning mechanism, so that the rack 33 meshes with the second gear 32. Then, when the cleaning mechanism continues to drive the rack 33 to move, the rack 33 will drive the second gear 32 to rotate. The rotation of the second gear 32 drives the third rotating shaft 29 to rotate. The rotation of the third rotating shaft 29 drives the driven bevel gear 30 to rotate. Since the driven bevel gear 30 meshes with the driving bevel gear 31, one of the connecting shafts 25 of the clamping mechanism is driven to rotate; When it is necessary to remove the power distribution network load monitoring device from the wire after the monitoring is completed, the rack 33 moves back to the reset position, driving the second gear 32 to rotate in the reverse direction, thereby driving one of the connecting shafts 25 of the clamping mechanism to rotate in the reverse direction.

[0038] Working principle: When the power distribution network load monitoring device is in use, the following steps are involved: Step S1: When performing the monitoring installation, first place the base 1 at the lower end of the wire and insert the wire into the cleaning mechanism; Step S2: Drive the cleaning mechanism to move horizontally through the moving mechanism, so that the cleaning mechanism moves from one side of the base 1 into the base 1 and then to the other side of the base 1, that is, the cleaning mechanism moves horizontally along the outer surface of the wire. The dust on the outer surface of the wire is removed by the cleaning mechanism, so that the monitored part of the wire is kept clean, avoiding the influence of dust on the monitoring effect and accuracy; Step S3: When the cleaning mechanism is about to move from the base 1 to the other side of the base 1, through the action of the transmission component, drive the clamping mechanism to work, so that the clamping mechanism closes and clamps on the outer surface of the wire, so that the current transformer 2 is in contact with the outer surface of the wire, and the load of the power distribution network is monitored through the current transformer 2; Step S4: When the cleaning mechanism moves to the other end of the base 1 and the current transformer 2 monitors the wire, through the work of the jitter dust removal mechanism, the dust adhered to the cleaning mechanism and cleaned from the wire surface can be jittered and removed, so that the cleaning mechanism can automatically remove dust, ensuring the dust cleaning effect on the wire during the next use operation; Step S5: When it is necessary to remove the power distribution network load monitoring device from the wire after the monitoring is completed, reverse the operation of the driving mechanism, so that the cleaning mechanism moves in the reverse direction. First, under the action of the transmission component, drive the clamping mechanism to disengage from the wire, and then the cleaning mechanism is reset from the base 1. After the cleaning mechanism is reset, manually operate the cleaning mechanism to make the wire disengage from the cleaning mechanism, and then the power distribution network load monitoring device can be removed.
