Abstract

The invention provides a snow making device for a V-shaped insulator chain snow covering test and an operation method thereof. The device comprises a test cabin, a water supply unit and an air supply unit, wherein the air supply unit is arranged in the test cabin; a bracket is arranged at the top in the test cabin; a spraying gun is arranged above the bracket. The improvements are as follows: the spraying gun is respectively connected with the air supply unit and the water supply unit through pipes; insulators are arranged in a V shape and suspended on the bracket; air and water in the spraying gun are mixed and atomized for spraying out from a nozzle to form snow drop in the test cabin; a water way electromagnetic valve and an air way electromagnetic valve can be regulated to adjust the water supply flow and the air supply flow for ensuring that the covered snow dropping on the V-shaped insulator chain satisfies the test requirements. Compared with the prior art, the snow making device for the V-shaped insulator chain snow covering test and the operation method thereof, provided by the invention, can regulate the covered snow position, thickness, density, area, temperature and uniformity on the insulator chain and the snowmelt conductivity to achieve the effective snow covering environment test.

Description

technical field [0001] The invention relates to a snow-making device, in particular to a snow-making device for a V-shaped insulator string snow-covering test and an operation method thereof. Background technique [0002] The electric energy generated by the generator is boosted by the transformer, and then connected to the transmission line through the circuit breaker and other control equipment to realize the power transmission. According to the structural form, transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines are erected on the ground and are composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc. According to the nature of the transmission current, power transmission is divided into AC transmission and DC transmission. [0003] In recent years, with the continuous acceleration of China's electric power development, China's power grid has also developed r...
