The invention discloses a low-voltage overhead line current measuring and patrolling device, relates to power distribution network current detection equipment, and aims to solve the problems that the manual and mechanical cooperation efficiency of a low-voltage overhead line load current measuring mode is low, resources are wasted, and faults are difficult to find in daily patrolling of hidden low-voltage power distribution equipment. Comprising an insulating rod body, a pincerlike current detection device and a current reading device, the current reading device comprises an image acquisition device and an image receiving device; a pincerlike current detection device and an image acquisition device are fixed at the top end of the insulating rod body; an image acquisition end of the image acquisition device faces a current reading screen of the pincerlike current detection device; and an image signal output end of the image acquisition device is electrically connected with an image signal input end of the image receiving device.
Description
technical field [0001] The invention relates to a distribution network current detection device. Background technique [0002] The measurement of the load current of the low-voltage overhead line is an important means to grasp the load distribution of the station area. It mainly measures the current of each branch line, conducts data analysis, and finds the users who steal electricity. And in remote rural areas, overhead lines are still the main way of power transmission. Pin insulators are widely used. In winter, the temperature is low, the surface of the insulator freezes and expands, and the insulator often bursts, resulting in insulation damage, breakdown discharge, and increased line loss. Case. In actual work, the following problems exist in the load current measurement of low-voltage overhead lines and the daily inspection of low-voltage power distribution equipment: [0003] 1. Because the low-voltage overhead line is on a 10-meter pole tower, the load current meas...
