Description
Technical field
The present invention relates to a kind of composite insulator bending fatigue testing method and device, belong to electric power transfer unit manufacturing machine technical field.
Background technology
Composite insulator is a kind of long clavate puncture-proof composite insulator, and its plug is the glass-epoxy leading-drawing rod, the tensile strength height.The outside coats the good silicone rubber jacket of one deck insulating property, and the protection plug is avoided atmospheric corrosion.For guaranteeing the interface quality of sheath and plug, the necessary linkage interface of manufacturing technique requirent sheath and plug is tight, the bonding strength height.But composite insulator usually runs into strong wind when moving in electrical network waves, and can be subjected to bending stress.Whether this long-time bending stress influential to the aspects such as bonding quality of composite insulator physical strength, sheath and plug interface quality, sheath and full skirt? for this reason, need a kind of accelerated deterioration equipment of research to composite insulator carry out aging test, ultimate strength is tested the problems referred to above is studied.
Summary of the invention
Technical matters to be solved by this invention is: design a kind of large deflection test method and equipment, and the crooked compound and limit load that the analog composite insulator is suffered on the line, accelerated test is studied the influence to the compound inslation protonatomic mass.
Technical solution of the present invention is to utilize a steel towers, fixes two guide rails, two dollies up and down, above dolly by the wire rope on the windlass, can drive dolly and slide up and down.One pressure transducer is installed under the following dolly.Between two dollies insulator is installed, by the positive and negative rotation of windlass, dolly pumps in the formation, forms the composite insulator bending motion.
Beneficial effect: the invention provides a kind of composite insulator bending fatigue testing method and device, realize the aging test to the bonding quality of composite insulator physical strength, sheath and plug interface quality, sheath and full skirt, the detection of ultimate strength test, guaranteed the quality of composite insulator.
