Description

Technical Field

[0001] The present invention belongs to the technical field of power fault detection, and particularly relates to a power fault detection device. Background Art

[0002] Overhead line power transmission is the main power transmission method adopted since the development of the power industry. However, overhead lines are exposed to the atmospheric environment and are directly affected by meteorological conditions. They must have a certain mechanical strength to adapt to local temperature changes, strong storm attacks, ice load, and floods that may be encountered when crossing rivers. At the same time, lightning strikes, rain, wet fog, and natural and industrial pollution will also damage or reduce the insulation strength of overhead lines and even cause power outages. Currently, the main method for fault detection is the injection signal detection method. The invention with the application number CN106291248A discloses a power cable fault detection device. This invention installs the base on the carrier using fastening bolts, and the clamping plate is installed in the card slot, reducing the occupied space and facilitating disassembly. The voltage transformer and the Hall current sensor jointly measure the power cable, and the fault point can be judged according to the voltage change situation and the magnetic field change situation, with higher detection efficiency compared to the traditional manual line inspection. However, there are still deficiencies in the detection process of this power cable fault detection device: First, there is an alternating electric field around the high-voltage cable during operation, which will charge and adsorb dust. During the detection of the cable by the above power cable fault detection device, the dust particles on the cable surface and the rolling brush surface cannot be cleaned. During power fault detection, dust, especially insulating dust, will form a barrier layer between the rolling brush and the cable, resulting in poor contact, affecting the signal acquisition accuracy, and hard dust such as quartz particles will accelerate the wear of the rolling brush and shorten its service life. When using a drone for fault detection, due to a certain error between the flight trajectory of the drone and the trajectory of the cable, the detection mechanism and the cable are prone to deviation during the flight of the drone, affecting the detection accuracy. Second, the above power cable fault detection device cannot detect the surface defects of the cable, and cannot quickly remove the rainwater in the defect. The rainwater seeps into the cable defect, which may cause partial discharge. At this time, the voltage transformer may detect an abnormal signal, easily causing deviation in the power fault detection result.

[0003] To solve the above problems, a power fault detection device is proposed in this application. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By arranging a drop compensation mechanism, the drop compensation mechanism enables the rolling electric brush on the fault detection mechanism to always be in close contact with the cable without generating impact force, which can improve the detection effect of the fault detection mechanism. The drop compensation mechanism is clamped to the bottom of the drone through a fixed buckle, which is convenient for disassembly and assembly. By arranging a cleaning module, the driving motor on the cleaning module can drive the purging mechanism to rotate and blow air through the driving gear. When the purging mechanism rotates and blows air, it can indirectly drive the inner sleeve to rotate through the annular gear. When the inner sleeve rotates, it can drive the cleaning component to rotate. The cleaning component can quickly clean the dust adsorbed on the surface of the cable, which can avoid the formation of a barrier layer between the rolling electric brush and the cable by dust, especially insulating dust, during the power fault detection, resulting in poor contact and affecting the signal acquisition accuracy.

[0016] When the linkage gear on the purging mechanism rotates driven by the driving gear, it can drive the blower impeller to rotate rapidly. The rapid rotation of the blower impeller in combination with the electric heating component can blow out hot air, which can not only quickly dry and remove the rainwater on the cable surface and at the cable surface defects, avoid deviation in the power failure detection results, and effectively eliminate abnormal influences, but also melt some of the ice layers remaining on the cable surface, which can prevent the poor contact between the rolling brush and the cable caused by the existence of the ice layer. By setting the defect detection camera, the defect detection camera can detect the defects on the cable surface in all directions driven by the rotation of the inner kit.

[0017] By setting the fault detection mechanism, when detecting, the rolling brush on the fault detection mechanism rolls along the power cable, and can measure and detect the power cable in cooperation with the voltage transformer and the Hall current sensor. According to the voltage change situation and the magnetic field change situation, the fault point can be judged. By setting the first marking mechanism and the second marking mechanism, the fault point detected by the fault detection mechanism and the surface defect point detected by the defect detection camera can be marked with different colors respectively through the first marking mechanism and the second marking mechanism, which is convenient for subsequent repair; By setting a cleaning brush under the rolling brush, the cleaning brush can clean the dust adhered to the surface of the rolling brush, which can not only avoid poor contact and affect the signal acquisition accuracy, but also effectively avoid the wear of the rolling brush. When detecting the fault of the power cable, the flight route of the drone is collected, and the flight route of the drone is compared with the conventional layout route of the cable, and the sag of the cable can be detected.
