Abstract

The invention discloses a wire icing thickness measurement and equivalent conversion method in a phytotron. The method comprises steps as follows: (1) calculating the radius of a wire and measuring the quality and the length of the wire; (2) performing icing on the wire; (3) measuring and converting the icing quality of the wire; (4) calculating the icing volume of the wire; (5) calculating the icing thickness of the wire; (6) repeating steps (2) to (5) and continuously calculating the icing thickness of the wire. With the adoption of the method, the icing thickness of the wire can be measured quickly and continuously, and the measuring method is simple, efficient and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a method for measuring and equivalently converting the ice thickness of wires in an artificial climate chamber. Background technique [0002] Affected by special geographical and climate characteristics, power grid freezing disasters frequently occur in southern China and a few northern regions. In order to grasp the characteristics and laws of power grid icing and provide a theoretical basis for power grid anti-icing work, relevant scholars at home and abroad have carried out power transmission in artificial climate chambers. Experimental research on ice coating growth of line conductors. A basic task of this experimental study is to measure the ice thickness of the wire. [0003] However, there are two main methods for measuring the icing thickness of conductors commonly used at present: one method is to directly measure the icing thickness of conduc...
