Description

Technical Field

[0001] The invention relates to the technical field of high-voltage cable maintenance, in particular to a lead seal monitoring device for high-voltage cable accessories. Background Art

[0002] The high-voltage cable lead-sealed joint structure is a key component of the high-voltage cable. If it cracks due to tension, vibration, etc. during installation or operation, the sealing of the accessory will be damaged, which will lead to extremely destructive high-voltage cable accidents. Defects in high-voltage cable lead-sealed accessories will not only occur on the outside of the accessories, but also on the inside. In addition, the lead-sealing process level of the joints is not uniform, and the surface is not smooth. At the same time, destructive testing cannot be used for the detection of high-voltage lead seals, and comprehensive testing is difficult and the accuracy is not high.

[0003] In order to detect the status of the high-voltage cable grounding system, the most common method currently used is eddy current testing. Its principle is to use the principle of electromagnetic induction to non-destructively evaluate certain properties of conductive materials and their workpieces by detecting the changes in the induced eddy currents in the workpiece being tested. In industrial production, eddy current testing is one of the main means to control the quality of various metal materials and a few non-metallic materials and their products. Compared with other non-destructive testing methods, eddy current testing is easier to automate, especially for profiles such as tubes, rods and wires. It has a high detection effect.

[0004] At present, eddy current flaw detection is used to detect high-voltage cable seals. Professional equipment is used to detect each cable seal or the seal that has been determined to be damaged. The detection workload is large, and it is impossible to monitor the seals in real time. Therefore, it is difficult to repair the damaged seals in time and predict the life of the seals. Summary of the invention

[0005] In order to solve the problem of difficulty in detecting the lead seal of a high-voltage cable and realize real-time monitoring of the lead seal of the high-voltage cable, the present invention provides a lead seal monitoring device for high-voltage cable accessories.

[0006] The present invention provides a high-voltage cable accessory lead seal monitoring device that adopts the following technical solution:

[0007] A high-voltage cable accessory seal monitoring device includes a subsystem end, a relay system end and a master control system end. Multiple groups of subsystem ends are communicatively connected to the same relay system end, and multiple relay system ends are connected to the same master control system end. Each relay system end is responsible for the subsystem ends of a region and collects data for transmission to the master control system end. The subsystem end includes a monitoring component and a structural component. The physical end of the monitoring component is installed on the structural component. The signal end of the monitoring component is connected to the cable seal structure. The structural component includes a clamp, and the clamp is clamped on the cables at both ends of the cable seal. The monitoring component includes an eddy current flaw detector. The eddy current flaw detector uses electromagnetic induction eddy currents to perform non-destructive flaw detection on the cable seal structure. The eddy current flaw detector is fixedly installed by a clamp.

[0008] The subsystem end, relay system end and master control system end are used for three-level data collection and transmission. The subsystem end is conducive to real-time monitoring of each seal position. The relay system end is convenient for responding to the abnormal state of each seal monitored. At the same time, it is conducive to collecting multiple groups of data to the master control system end, reducing the data transmission pressure of the master control system end. The master control system end is used to collect and summarize all seal status monitoring data, control and query all seal monitoring, and the monitoring component is used to realize the monitoring of various data of the seal status, more comprehensively grasp the seal status, realize real-time monitoring and life prediction of the seal, and the structural component is used to fix the monitoring component to the seal position, which is conducive to the protection of the seal and simple maintenance operations.

[0009] Furthermore, the structural assembly also includes an exhaust fan, a sun visor and a shock absorber. The exhaust fan is installed on a clamp. The same set of clamps are connected and tightened by connecting rods. The sun visor is sleeved on the cable on the upper part of the cable seal, and the shock absorber is sleeved on the cables on both sides of the cable seal.

[0010] The exhaust fan helps to keep the seal dry, reduce the corrosion of water on the seal, and increase the life of the seal. The sun visor is used to block direct sunlight, which helps to maintain the temperature of the seal and avoid direct sunlight exposing the seal to excessive temperature and thus damaging the seal. The shock absorber is used to reduce the damage to the seal caused by vibration of structural components and cables under the action of wind.

[0011] Furthermore, the exhaust fans are symmetrically arranged with respect to each other, and the exhaust directions of the two relative exhaust fans are opposite and toward the cable seal position. The exhaust fans blow air obliquely toward the cable seal position and exhaust air from the sides of the cable seal. The sun visor main body is reflective cloth and is supported by memory metal strips to form an umbrella shape. The memory metal strips display two states of extension and curling according to different temperatures. The shock absorber is installed between the clamp and the exhaust fan.

[0012] The exhaust directions of the two exhaust fans are relatively set to blow air to both ends of the lead seal and blow air out from both sides, adapting to the shape of the lead seal that is narrow at both ends and wide in the middle. The sun visor is supported by memory metal strips, which can automatically sense the temperature and stretch and contract, which is beneficial for shading when the temperature is high and increasing the heat dissipation area when the temperature is low.

[0013] Furthermore, the exhaust fans on both sides of the cable seal are connected to each other through a connecting rod. The connecting rod is in the shape of a long strip and is relatively inclined, and the inclination direction of the connecting rod is opposite to the inclination direction of the exhaust fan blades. Natural wind drives the connecting rod to rotate and drives the exhaust fan to rotate at the same time. The direction of air circulation is that the exhaust fan delivers air to the cable seal position and then discharges it through the gap between the connecting rods.

[0014] The long plate-shaped connecting rod utilizes wind energy to control the rotation of structures such as the exhaust fan. The inclination direction of the connecting rod is opposite to the inclination direction of the exhaust fan blades, so that the wind direction at the exhaust fan and the connecting rod is opposite, thereby realizing air circulation.

[0015] Furthermore, the eddy current flaw detector includes multiple probes, which are installed on the connecting rod and rotate with the exhaust fan and the connecting rod. The probes of the eddy current flaw detector perform flaw detection on a circle of the cable seal as the connecting rod rotates, and the cable seal is divided into multiple layers along the radial direction, and a probe of the eddy current flaw detector is installed at each layer.

[0016] The multiple probes of the eddy current flaw detector can conduct a relatively comprehensive detection of the radial direction of the lead seal, and realize a comprehensive detection of the axial circle of the lead seal as the exhaust fan and the connecting rod rotate, ensuring the comprehensiveness of the lead seal monitoring.

[0017] Furthermore, the monitoring component also includes a temperature sensor, a humidity sensor and a vibration sensor. The temperature sensor is installed outside the cable seal and the waterproof wrapping layer, the humidity sensor is installed between the cable seal and the waterproof wrapping layer, and the vibration sensor is installed on the cable at one end of the cable seal.

[0018] The temperature sensor, humidity sensor and vibration sensor monitor the temperature data, humidity data and vibration data of the lead seal position respectively, which is conducive to using these data to conduct a comprehensive analysis of the life of the lead seal and obtain a more accurate life prediction.

[0019] Furthermore, the eddy current flaw detector, temperature sensor, humidity sensor and vibration sensor are connected to a power supply via wires, the power supply contains a battery and is externally connected to a power supply, the eddy current flaw detector, temperature sensor, humidity sensor and vibration sensor are connected to a data box via a signal line, and the data box collects real-time data information from the eddy current flaw detector, temperature sensor, humidity sensor and vibration sensor and sends it to the relay system end.

[0020] The power supply is used to supply power to sensors and monitoring instruments, and the data box is used to temporarily store the data information collected by the sensors.

[0021] Furthermore, an alarm component is installed on the structural component, and the alarm component includes a flash light, a frequency responder and a digital display. The flash light, the frequency responder and the digital display are connected to the data box through a signal line. When the flash light and the frequency responder receive an abnormal signal higher than a set value emitted by the data box, they emit regular strobe and frequency response. When the digital display receives an abnormal signal higher than a set value emitted by the data box, it displays an abnormal situation code.

[0022] The flashing light and frequency responder of the alarm component are used to warn passers-by not to approach and remind maintenance personnel of the lead seal position that needs to be repaired, so that maintenance personnel can quickly confirm the repair location and perform repairs in time. The digital display shows the abnormal situation code to help auxiliary maintenance personnel quickly determine and confirm the cause of the abnormal state, so as to facilitate timely and targeted repair or maintenance.

[0023] Furthermore, the relay system end includes a data collector, a data processor and a data transmitter. The data collector is communicatively connected to the monitoring component. The data collector collects data information collected from the monitoring component, and the data information includes fault information and location information. The data processor is communicatively connected to the data collector. The data processor processes the fault information and location information collected by the data collector, divides the fault information into fault levels, and converts the location information into map coordinates. The data transmitter is communicatively connected to the master control system end and the nearest maintenance management end. The data transmitter selectively sends the fault information and location information to the nearest maintenance management end according to the fault level. The data transmitter packages the fault information and location information as well as the processed fault level and map coordinates and sends them to the master control system end and shares information with the master control system end.

[0024] The data collector is used to collect and integrate data sent by multiple subsystem ends, and the data processor is used to preliminarily process the information collected by the data collector. In addition, since the data processing equipment is installed in the relay system end, the equipment on the subsystem end is simplified, and the weight of the equipment on the subsystem end is reduced, which reduces costs and facilitates installation and maintenance. The data transmitter sends the processed data to the master control system end.

[0025] Furthermore, the master control system end includes a data storage device, a data analyzer and a data display. The data storage device is communicatively connected to the data transmitter, the data storage device collects the packaged data information sent by the data transmitter and stores it by classification. The data analyzer is communicatively connected to the data storage device, the data analyzer calls the data information stored in the data storage device and predicts the life of the cable seal by self-learning. The data display is communicatively connected to the data storage device and the data analyzer, and the data display displays the data information stored in the data storage device and the life information analyzed and predicted by the data analyzer.

[0026] The data storage device is used to store the data collected by the relay system, which is convenient for calling and viewing historical data. The data analyzer uses simulation algorithms and combines the data in the data storage device to control the seal status and predict the seal life. The data display is used to display the information analyzed by the data analyzer, which is convenient for management personnel to view.

[0027] In summary, the present invention has the following beneficial technical effects:

[0028] 1. Use the subsystem end, relay system end and master control system end to collect and transmit three-level data. The subsystem end is conducive to real-time monitoring of each seal position.

[0049] The structural component 12 includes a clamp 121, which is clamped on the cables at both ends of the cable seal 20. The monitoring component 11 includes an eddy current flaw detector 111, which uses electromagnetic induction eddy currents to perform non-destructive flaw detection on the cable seal 20 structure. The eddy current flaw detector 111 is fixedly installed by the clamp 121.

[0050] Subsystem end 1 sends the collected lead seal 20 status data to relay system end 2, and relay system end 2 receives the original electrical signal information of the lead seal 20 status data sent by subsystem end 1. Relay system end 2 includes a data calculation and processing device and system of the eddy current flaw detector 111, and also includes other sensor signal data calculation and processing devices and systems. The data sent by different subsystem ends 1 are centrally stacked, and then relay system end 2 processes and feeds back in sequence according to the stacking order, and the processed data information is sent to the master control system end 3, and the master control system end 3 further processes the data.

[0051] When installing the clamp 121, if one end of the cables 10 on both sides is cut off, it is inserted from the cut side and welded to fix. If both sides of the cables 10 on both sides are not cut off, the clamp 121 is divided into two semicircular arcs, and then assembled and installed on the cables 10 and covered, and finally welded to fix.

[0052] Embodiment 2:

[0053] On the basis of Example 1, add:

[0054] Reference Figure 1 and Figure 2 The structural component 12 also includes an exhaust fan 122, a sun visor 123 and a shock absorber 124. The exhaust fan 122 is installed on a clamp 121. The same set of clamps 121 are connected and tightened with each other through a connecting rod. The sun visor 123 is sleeved on the cable 10 on the upper part of the cable seal 20, and the shock absorber 124 is sleeved on the cables 10 on both sides of the cable seal 20.

[0055] The exhaust fan 122 is installed on the clamp 121 through a ratchet, and the ratchet limits the exhaust fan 122 to one-way rotation. The sun visor 123 is set to different sizes and shapes according to the position and swing direction of the lead seal 20. Through cutting, it can ensure the shielding effect and save materials at the same time. The shock absorber 124 includes air pressure shock absorption, spring shock absorption and rubber shock absorption, and shock absorption is achieved through the elasticity of gas, spring and rubber.

The connecting rod 120 is a long strip and relatively inclined, and the inclination direction of the connecting rod 120 is opposite to the inclination direction of the exhaust fan 122 blades. The natural wind drives the connecting rod 120 to rotate and drives the exhaust fan 122 to rotate at the same time. The air circulation direction is that the exhaust fan 122 delivers air to the position of the cable seal 20 and then discharges it through the gap between the connecting rod 120.
