Problems solved by technology
The icing of insulators is one of the causes of serious damage to the power system. Severe icing will lead to a sharp decline in the electrical performance of transmission line insulators, resulting in flashover failures, and even accidents such as falling towers and broken poles.
At present, some research units use large-scale artificial climate chambers to study the icing of the entire insulator string. There is no test machine that can systematically study the icing on the surface of a single insulator shed, and the mechanism of icing on the shed surface Experimental research, the existing artificial climate chamber can not meet the requirements of experimental accuracy

The invention relates to a composite insulator umbrella skirt surface icing tester and a testing method. A water storage tank is fixedly mounted at the left end of the base. A rotating shaft glass cover is fixedly mounted on the step at the lower surface in a housing. The rotating shaft glass cover is internally provided with an inclination angle adjusting mechanism which is used for adjusting inclination angle of a to-be-tested insulator. The end of the inclination angle adjusting mechanism is provided with a clamping mechanism for clamping an insulator. A bracket on the side surface of the clamping mechanism is provided with an injector device which is used for quantitatively injecting liquid. The injector device is mounted on an injector height adjusting mechanism. The injector device is connected with a transmission mechanism. The bracket at the side surface of the clamping mechanism is also provided with an image photographing device. The tester can be used for researching relationship between composite insulator umbrella skirt surface icing and a surrounding electric field and a surrounding environment, and obtains a corresponding testing result through testing, thereby supplying a testing data for theoretical research for a composite insulator umbrella skirt surface icing mechanism.
Description
technical field [0001] The invention relates to a composite insulator shed surface performance testing machine, in particular to a composite insulator shed surface ice coating test machine. Background technique [0002] Insulators are an important part of overhead transmission lines. They are used for flexible or rigid support of electrical conductors and equipment and to insulate and isolate conductors and equipment from ground or other wires and equipment. Therefore, the mechanical and electrical properties of insulators affect transmission lines. safe and stable operation. The icing of insulators is one of the reasons for causing serious damage to the power system. Severe icing will lead to a sharp decline in the electrical performance of transmission line insulators, resulting in flashover faults, and even accidents such as tower collapse and pole breaking. At present, some research units use large-scale artificial climate chambers to study the icing of the entire insul...
