Abstract

The invention discloses an electric power grid ultra-high voltage electric transmission and distribution line composite insulator slicing sampling apparatus, which comprises a cutter blade installation seat (9) and a cutter blade (10), wherein the cutter blade (10) is fixedly arranged on the cutter blade installation seat (9). The electric power grid ultra-high voltage electric transmission and distribution line composite insulator slicing sampling apparatus is characterized by comprising a racket (1), a clamping pincers (2), a motor (4), a drive belt (5), a cutter blade moving screw rod drive nut (6), a cutter blade moving screw rod (7) and a rotation connection block (8). According to the present invention, the operation of the whole sampling process of the apparatus is convenient, and the automatic cutting is achieved through the matching of various devices of the whole apparatus; the whole apparatus has the simple structure, the whole slicing process can be completed at the high-altitude, and the condition that the composite insulator is disassembled from the line, is conveyed to the ground and then is cut and sampled is not required; the charged work can be directly performed; the structure of the whole set of the apparatus is simple, and the weight is light; and different sampling requirements can be met, and the sheets with different thicknesses can be cut.

Description

technical field [0001] The invention belongs to the field of composite insulator testing equipment, and in particular relates to a composite insulator slice sampling device for ultra-high voltage transmission and distribution lines of a power grid. Background technique [0002] With the vigorous development of UHV projects, more and more composite insulators are used in UHV transmission and distribution lines in my country. Since the outer insulating material of composite insulators is silicone rubber, the voltage level is increased and the operating environment is harsh. Make its aging problem prominent. The evaluation of the aging state and remaining life of composite insulators is concerned by the circuit department. [0003] In recent years, Fourier transform infrared spectroscopy (Fourier transform infrared, FTIR) has been used more and more to test the aging state of composite insulators. The method requires only a small amount of material, basically does not damage t...
