Embodiment

[0020] Such as figure 1 Shown is a front view of a structure diagram of a device for detecting the lead-sealing state of a large-thickness non-metallic cladding layer accessory. Such as figure 1 As shown, a cuboid box 100 made of PVC material is included. A plurality of ports are opened on one side of the cuboid 100 , which are the probe connection port 110 on the adjacent left side of the side of the cuboid 100 ; and the communication port 120 on the right side of the probe connection port 110 . On the right side of the communication port 120, there are up and down settings, with two on the top and two on the bottom. The upper two ports are respectively the redundant communication port 140 adjacent to the communication port 120 and the power port 150 adjacent to the right side of the redundant communication port 140 , and the lower two ports are both charging indication ports 130 . Such as figure 1 The shown device mainly includes a sensor and a remote signal transmission...

Abstract

The invention discloses a device and a method for detecting the lead sealing state of a large-thickness nonmetal coating accessory. The device comprises a cuboid, a sensor and a remote signal transmission module, and a plurality of ports are formed in one side of the cuboid. The device is characterized in that a probe connecting port is arranged on the adjacent left side of one side of the cuboid,a communication port is arranged on the right side of the probe connecting port, and on the right side of the communication port, ports are arranged in an up-down manner, two ports are arranged on the upper side, and two ports are arranged on the lower side. According to the device for detecting the lead sealing state of a large-thickness nonmetal coating accessory, it is guaranteed that the detection sensor is perpendicular to the detection face, a reference test block and an eddy current sensor cannot generate inclination angles in the adjustment process, and the potential fault hazard caused by the fact that the reference test block and the eddy current detection sensor are held and stabilized by people is avoided.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to the field of power grid detection, in particular to a device and method for high-voltage cable lead seal detection. Background technique [0002] With the increase of power demand and the continuous expansion of the scale of the power grid, it is necessary to comprehensively use advanced technology and management methods to ensure the health of equipment and lines is an important basis for the safety and reliability of the power grid. Currently, power grid companies traditionally implement periodic operation and maintenance and main line online Real-time monitoring, such as the application of various technologies such as partial discharge detection, optical fiber temperature measurement, and metal sheath grounding current monitoring, has been widely used in cable defect diagnosis, effectively improving the safe operation of equipment and main lines, but the detection of high-v...
