Problems solved by technology
However, the number of insulators used in ultra-high voltage power transmission and transformation can reach more than 60 pieces, and the entire string length is about ten meters. The commonly used insulator detection method is due to the large disturbance of the operating rod, heavy weight, and high labor intensity. , basically not suitable for UHV line insulator detection

The invention relates to a device suitable for detecting UHV insulators. The device includes an insulating guide rail, an insulator detector, a pulley, a take-up wheel, two pulley blocks and insulating ropes. One pulley block is installed on the beam of a portal structure tower, and the other A block of pulleys is installed on one end of the insulating guide rail; the other end of the insulating guide rail is fixedly connected to the gantry tower through a hoop; the trolley is installed on the insulating guide rail, and the insulator detector is connected to the trolley through a connecting rod The take-up wheel is set on the insulating guide rail near one end of the gantry tower, the insulating rope passes through the take-up wheel and two pulley blocks, and the pulley is also connected with the insulating rope. The device of the invention can detect the state of the insulator string in real time, reduces the instability of manual operation through mechanical means, improves the detection accuracy, and reduces the danger caused by manual operation at the same time.
Description
technical field [0001] The invention relates to the detection of insulators, in particular to a device and method suitable for detection of UHV insulators. Background technique [0002] The UHV power grid is of great significance to realize the intensive development of energy resources, optimize the allocation of energy resources, improve energy utilization efficiency, promote the upgrading of power industry technology, promote sustainable economic and social development, and build a harmonious society in an all-round way. At present, AC and DC UHV lines of different voltage levels have been built and put into operation one after another, such as the 1000kV Jinnanjing line and the 800kV DC upward line. However, with the increase in the number of lines in operation, strengthening the operation and maintenance of UHV lines is a problem that cannot be ignored to ensure the safe and stable operation of the power grid. [0003] Insulators, as a large amount and a wide variety of...
