Abstract

The invention discloses a method and a device for an endurance bending test of a composite insulator. The device consists of a motor (1), a belt pulley (2), a belt (3), a belt pulley (4), a speed reducer (5), a coupling (6), a roller (7), a descending wire rope (8), a descending wire rope (9), an ascending wire rope (10), an iron tower (11), an upper fixed pulley (12), an upper pulley block (13), a slide rail (14), a lower pulley block (15), a lower fixed pulley (16), a pressure sensor (17), the composite insulator (18) and a digital display meter (19). The method and the device realize the aging tests on the mechanical strength of the composite insulator, the interface quality of a jacket and a core rod, and the bonding quality of the jacket and an umbrella skirt, and the detection on an ultimate strength test, and ensure the quality of the composite insulator.

Description

technical field [0001] The invention relates to a bending fatigue test method and device of a composite insulator, and belongs to the technical field of electric power transmission component manufacturing machinery. Background technique [0002] The composite insulator is a long rod-shaped non-breakdown composite insulator, and its core rod is a fiberglass epoxy resin lead-out rod with high tensile strength. The outside is covered with a layer of silicone rubber sheath with excellent insulation performance to protect the mandrel from atmospheric corrosion. In order to ensure the quality of the interface between the sheath and the mandrel, the production process requires that the sheath and the mandrel must be connected with a tight interface and high bonding strength. However, when composite insulators are operated in the power grid, they often encounter strong winds and will be subject to bending stress. Does this long-term bending stress affect the mechanical strength of...
