Description

Technical Field

[0001] The present invention relates to the technical field of electrical cabinet fault monitoring and measurement, and in particular to an electrical cabinet fault monitoring device capable of rapid positioning. Background Art

[0002] When the electrical cabinet is in use, magnetic sensors are installed near the main bus, branch lines and key electrical equipment (such as transformers, contactors, etc.) according to the circuit layout inside the electrical cabinet. When the magnetic sensor is working, it will monitor the strength and direction of the surrounding magnetic field and other parameters in real time. When the monitoring line is in normal use, the magnetic field it generates is relatively stable, and the signal output by the magnetic sensor is also maintained within a certain range. Once a fault occurs in the electrical cabinet, such as a line short circuit or overload, it will cause abnormal changes in the current, which in turn causes changes in the magnetic field. The magnetic sensor can detect these changes in time and convert them into electrical signals and transmit them to the monitoring system. After receiving the signal from the magnetic sensor, the monitoring system will use an algorithm to analyze and process the data, and determine whether there is a fault by comparing it with the pre-set normal magnetic field threshold. If an abnormal magnetic field is detected, the system will further analyze the characteristics of the magnetic field change, such as the amplitude and frequency of the change, to locate the fault. In order to achieve rapid positioning, an array composed of multiple magnetic sensors is used for monitoring.

[0003] During the monitoring process, the magnetic sensor needs to be facing the surface of the wire and perpendicular to the axis of the wire to obtain a stable magnetic field signal. However, in the actual monitoring process, due to the excessive tightening of the fixing bolts of the monitoring wire during installation, unreasonable bracket spacing, or the mismatch between the wire length and the cabinet space, mechanical stress may be generated in the wire during the initial installation. The stress is released or accumulated during long-term operation, which will cause the wire at the monitoring position to bend and deform. Secondly, the monitored wire will generate Joule heat when the load current passes through it during normal operation. The temperature rises and causes the busbar to expand. The temperature drops during load fluctuations or power outages, causing the busbar to shrink. Repeated thermal expansion and contraction may cause the busbar to gradually deform due to material fatigue or uneven constraints at the fixed points. The bending deformation of the wire will cause the vertical distance or angle between the sensor and the busbar to change. According to the Biot-Savart law, the distance change will directly cause the measured value to deviate from the true value, affecting the reliability of electrical cabinet fault location. To this end, we propose an electrical cabinet fault monitoring device that can quickly locate. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0020] Preferably, the fault component includes two sets of side plates 201, a mounting plate 202 is centrally provided between the two sets of side plates 201, a magnetic sensor 204 for identifying changes in the magnetic field outside the busbar 103 is mounted on the mounting plate 202 through a positioning assembly, a through-hole 203 is provided on the mounting plate 202 for the end of the magnetic sensor 204 to pass through for installation, an annular cover 3 is fixed to the front side of the mounting plate 202, and a centering positioning assembly is provided on the annular cover 3 for assisting in centering the magnetic sensor 204; It should be noted here that: through the clamping component and the centering positioning component, the magnetic sensor 204 is installed on one side of the busbar 103 line body and perpendicular to the axial direction of the busbar 103 line body. When the magnetic sensor 204 is working, it will monitor the intensity and direction of the surrounding magnetic field and other parameters in real time. When the monitoring line is in normal use, the magnetic field it generates is relatively stable, and the signal output by the magnetic sensor 204 is also maintained within a certain range. Once a fault occurs in the electrical cabinet, such as a line short circuit or overload, it will cause abnormal changes in the current, which in turn causes changes in the magnetic field. The magnetic sensor 204 can detect these changes in time and convert them into electrical signals and transmit them to the monitoring system. After receiving the signal from the magnetic sensor 204, the monitoring system will use an algorithm to analyze and process the data, and determine whether there is a fault by comparing it with a pre-set normal magnetic field threshold. If an abnormal magnetic field is detected, the system will further analyze the characteristics of the magnetic field change, such as the amplitude and frequency of the change, to locate the position of the fault. In order to achieve rapid positioning, an array composed of multiple magnetic sensors 204 is used for monitoring; It is worth noting here that the magnetic sensor 204, the monitoring system and the algorithm within the monitoring system are conventional components for measuring magnetic variables and identifying and controlling in this application. Their working principles and operational connection methods are considered as prior art in this application and will not be elaborated on here.

[0021] Preferably, two groups of clamping assemblies are symmetrically arranged between the two groups of side panels 201. An adjustment assembly for assisting in adjusting the spacing between the two groups of side panels 201 and a guide assembly for guiding during the adjustment process are provided between the mounting plate 202 and the two groups of side panels 201. The clamping assembly includes a strip plate 601. A telescopic assembly for assisting in telescopic connection is provided between the strip plate 601 and the side panels 201.

The two groups of clamping plates 602 are provided with arc grooves 603 for abutting and clamping against the outer side of the busbar 103. It should be noted here that: by adjusting the assembly and the guide assembly, the two groups of side panels 201 are forced to move closer to each other, reducing the distance between the two groups of side panels 201. In the process of the two groups of side panels 201 moving closer to each other, through the connection between the telescopic assembly and the sliding assembly, the two groups of clamping plates 602 on the clamping assembly move toward the outside of the line body of the busbar 103 to be detected. During the movement, the arc groove 603 on the clamping plate 602 is clamped against the outside of the line body of the busbar 103. Through the clamping action and the connection between the telescopic assembly and the sliding assembly, the two groups of side panels 201 are clamped and fixed on the line body of the busbar 103 to be monitored.

[0022] Preferably, the telescopic assembly includes a plurality of first sleeves 701 fixed to the strip plate 601, each first sleeve 701 being evenly distributed around the strip plate 601, a first slide bar 702 being slidably connected to the first sleeve 701, one end of the first slide bar 702 being fixed to the side plate 201, and a first spring 703 being sleeved on the outer side of the first sleeve 701; It should be noted that: multiple sets of first sleeves 701 and first slide bars 702 are used to facilitate the telescopic connection between the strip plate 601 and the side plate 201, and the first spring 703 is used to facilitate reset after the telescopic movement.

The two sets of cross-shaped plates 802 are fixed with mounting blocks 903, and the two sets of mounting blocks 903 are fixed with transmission pins 904. The two sets of transmission pins 904 are respectively slidably connected to the two sets of inclined grooves 902 of the transmission plate 901; It should be noted here that: after the clamping plate 602 is clamped against the busbar 103 line body, the side plates 201 are made to contract toward the line body through the continued contraction movement of the two sets of side plates 201 and the limiting action of the busbar 103 line body on the clamping plate 602. In the process of movement, the two sets of inclined grooves 902 on the transmission plate 901 interact with the two sets of transmission pins 904 and the connection between the mounting block 903 and the cross-shaped plate 802, so that the two sets of clamping plates 602 that are clamped against the busbar 103 line body are pushed away from each other in the axial direction of the line body.

[0025] Preferably, the adjustment assembly includes a U-shaped frame 1001 fixed to the upper end of the mounting plate 202, a double-threaded tube 1002 is rotatably connected to the U-shaped frame 1001, and the threads at both ends of the double-threaded tube 1002 are arranged in opposite directions, and the two ends of the double-threaded tube 1002 are meshedly connected with screw rods 1003, and the ends of the two sets of screw rods 1003 away from the double-threaded tube 1002 are respectively fixed to the two sets of side plates 201, and a driving roller 1004 for driving the double-threaded tube 1002 is fixed to the double-threaded tube 1002; It should be noted here that: the double-headed threaded tube 1002 is driven to rotate by the driving roller 1004. Since the threads at both ends of the double-headed threaded tube 1002 are set in opposite directions, during the rotation of the double-headed threaded tube 1002, the double-headed threaded tube 1002 is respectively engaged with the two sets of screw rods 1003 to transmit the force to the two sets of side plates 201. During the movement of the two sets of side plates 201, the guiding effect of the guide assembly causes the two sets of side plates 201 to move closer to or away from each other after being subjected to force.

[0026] Preferably, two sets of guide assemblies are provided on the U-shaped frame 1001, and the two sets of guide assemblies are symmetrically arranged on both sides of the adjustment assembly.

[0027] Preferably, the centering positioning assembly includes a plurality of groups of sector-shaped positioning plates 401 disposed inside the annular cover 3, and each group of sector-shaped positioning plates 401 is disposed in a state of an annular array. An elastic assembly for assisting in elastically connecting the sector-shaped positioning plates 401 is disposed between the inner side of the annular cover 3 and the sector-shaped positioning plates 401. The sector-shaped positioning plates 401 are provided with an inclined surface 402 for abutting against the front end of the magnetic sensor 204 for transmission. It should be noted here that: the magnetic sensor 204 is installed on the mounting plate 202. During the installation process, the head of the magnetic sensor 204 is passed through the annular cover 3 and the through-hole 203 in turn. In the process of the head of the magnetic sensor 204 passing through the annular cover 3, the head of the magnetic sensor 204 is offset against the inclined surface 402 on each group of fan-shaped positioning plates 401. In the process of offsetting, each group of fan-shaped positioning plates 401 is pushed to move away from each other under force. After the head of the magnetic sensor 204 passes through, the elastic component squeezes and pushes each group of dispersed fan-shaped positioning plates 401, so that each group of fan-shaped positioning plates 401 is offset against the outer side of the passed magnetic sensor 204. Through the offset action of each group of fan-shaped positioning plates 401, the magnetic sensor 204 is centrally positioned and installed.

[0028] Preferably, the elastic component includes a plurality of third sleeves 501 fixed on the inner wall of the annular cover 3, a third slide bar 502 is slidably connected to the third sleeve 501, one end of the third slide bar 502 is fixed to the fan-shaped positioning plate 401, and a second spring 503 is sleeved on the outer side of the third sleeve 501, and the two ends of the second spring 503 are respectively set against the inner wall of the annular cover 3 and the fan-shaped positioning plate 401; It should be noted here that: multiple sets of third sleeves 501 and third slide rods 502 are used to assist the telescopic connection of the fan-shaped positioning plate 401, and the second spring 503 is used to elastically push the fan-shaped positioning plate 401 after the contraction movement.

[0029] In this solution: A device for monitoring faults in an electrical cabinet that can be quickly located includes the following steps: The magnetic sensor 204 is used to monitor the magnetic variables at the corresponding position of the busbar 103 to assist in quickly locating the fault inside the cabinet 101. During the use, the two sets of side plates 201 are moved. By moving the two sets of side plates 201, the line position of the busbar 103 to be monitored is placed between the clamping plates 602 of the two sets of clamping assemblies. After the positions of the two sets of side plates 201 are moved, the two sets of side plates 201 are forced to move closer to each other through the adjustment component and the guide component, thereby reducing the distance between the two sets of side plates 201. In the process of the two sets of side plates 201 moving closer to each other, the connection between the telescopic component and the sliding component causes the two sets of clamping plates 602 on the clamping component to move toward the outer side of the busbar 103 to be detected. In the process of movement, the arc groove 603 on the clamping plate 602 is clamped against the outer side of the busbar 103. Through the clamping action and the connection between the telescopic component and the sliding component, the two sets of side plates 201 are clamped and fixed to the busbar On the line body of the line 103 to be monitored, and after the clamping plate 602 and the busbar 103 line body are clamped against each other, the two sets of side plates 201 continue to move toward the line body and the busbar 103 line body limits the clamping plate 602, so that the side plates 201 move toward the strip plates 601 that are limited by the limit. During the movement, the two sets of inclined grooves 902 on the transmission plate 901 interact with the two sets of transmission pins 904 and the connection between the mounting block 903 and the cross-shaped plate 802, so that the two sets of clamping plates 602 that are clamped against the busbar 103 line body are pushed away from each other in the axial direction of the line body (see Figure 7 Since the clamping plates 602 are in a state of clamping against the busbar 103, the two sets of clamping plates 602 are pushed away from each other along the axial direction of the busbar, and the busbar 103 at the position to be monitored is pulled away from each other. The pulling action generates a pre-tightening force on the busbar, thereby preventing the busbar at the monitoring position from bending and deformation during subsequent monitoring. After the two sets of side plates 201 and the busbar 103 are clamped and fixed and the busbar 103 is pre-tightened, the magnetic sensor 204 is installed on the mounting plate 202. During the installation process, the head of the magnetic sensor 204 passes through the annular cover 3 and the through-hole 203 in sequence. During the process of the head of the magnetic sensor 204 passing through the annular cover 3, the head of the magnetic sensor 204 abuts against the inclined surface 402 on each set of sector-shaped positioning plates 401. During the abutment process, the sector-shaped positioning plates 401 are pushed to move away from each other under force. After the head of the magnetic sensor 204 passes through, the elastic component is used to press each sector-shaped positioning plate 401. The squeezing and pushing action of the dispersedly moving fan-shaped positioning plates 401 causes each group of fan-shaped positioning plates 401 to abut against the outer side of the passing magnetic sensor 204. Through the abutting action of each group of fan-shaped positioning plates 401, the magnetic sensor 204 is centrally positioned and installed. By centrally positioning and installing the magnetic sensor 204 and pulling and wrinkle-proofing the line body at the position to be monitored on the busbar 103, the axial direction of the magnetic sensor 204 and the busbar 103 line body are perpendicular during the monitoring process, avoiding changes in the vertical distance or angle during the monitoring process, ensuring the true value of the monitoring, and further improving the reliability of fault location of the electrical cabinet.
