[0036] The first embodiment: as figure 1 , image 3 , Figure 4 , Figure 5 , Image 6 with Figure 7 As shown, the No. 1 pulley mechanism 3 and the No. 2 pulley mechanism 9 are placed on the top of two adjacent groups of high-voltage cables at the same time, so that the cables are stuck on the inner surfaces of the No. 1 pulley 31 and the No. 2 pulley 91, so that the bottom surface of the No. 1 pulley mechanism 3 The connecting curved rod 33 is inserted into the mounting plate 24, and the locking sleeve 34 is installed on the connecting curved rod 33 from below, and the electroscope 143 is socketed on the high-voltage cable. At this time, the manned frame 1 and the loading Frame 12 hovers below the two sets of cables. The operator connects the safety rope on the outside of the safety suit to the buckle on the front of the manned frame 1. The operator lands in the manned frame 1 and detects the current position of the cable. After the inspection is completed, hold the con...

Abstract

The invention discloses a high-safety high-voltage live detection device in the technical field of high-voltage cable detection equipment, and discloses a high-safety high-voltage live detection device, which comprises a manned frame and an object carrying frame, the side surface of the manned frame is fixedly connected with a connecting rope, and the top surface of the connecting rope is fixedly connected with a mounting plate. The manned frame and the first pulley mechanism are pulled forwards, so that an operator can stand stably during high-altitude detection operation, the operator is prevented from climbing on a cable to carry out detection operation, the actual detection safety is greatly improved, and during actual continuous detection operation, convenient advancing can be achieved through manual operation, and the detection efficiency is improved. The convenience of live detection is greatly improved, an operator can easily carry out detection operation, the operation quality is prevented from being influenced when the operator climbs on the cable to move, the safety is ensured, effective detection of the high-voltage cable is realized, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of high-voltage cable detection equipment, in particular to a high-voltage live detection device for high safety. Background technique [0002] High-voltage power lines are the lifeblood of the national economy. Transmission lines and power equipment are ubiquitous in the actual power system. Their reliable and safe operation is directly related to the reliability of the entire power grid. Therefore, detecting the discharge status of transmission lines and power equipment has become a necessary means to grasp their operating status, and also an important guarantee to ensure the safe and reliable power supply of the power system. [0003] At present, when carrying out high-voltage live detection, it is usually necessary for the detection staff to wear protective clothing and climb on the high-voltage cable, and to detect the live cable through the electroscope equipment, and the operator is required to hang t...
