Sand and dust weather simulation testing system

Abstract

The invention discloses a sand and dust weather simulation testing system, and belongs to the technical field of power transmission line environmental simulation. An air pipe is divided into two parts including a high position level segment and a low position level segment, and two elbows and a section of perpendicular pipe segment are connected between the two parts. A fan is arranged at the position of an inlet of the low position level segment of the air pipe, and a feed pipe of a feeder is connected at the front end of the high position level segment of the air pipe. A transducer is connected with the regulating and controlling fan and the feeder, and an Annubar flowmeter is arranged at the rear portion of the low position level segment of the air pipe. Two flow directors are respectively arranged at the starting end and the tail end of the high position level segment of the air pipe. According to the sand and dust weather simulation testing system, the flow directors are adopted to manufacture whirlwind flow to accelerate sandstorm diffusion, and the sand and dust weather simulation testing system has the advantages of shrinking the diffusing air pipe, expanding the sandstorm affecting range and the like; the transducer is adopted to regulate and control the fan and the feeder, flow regulation and control is monitored through the Annubar flowmeter, and the test precision is high; and a sandstorm system is miniaturized and structuralized, and the device is concise and intuitionistic, and has strong mobility.

Description

technical field [0001] The invention relates to a sand and dust weather simulation test system for corona tests, belonging to the technical field of power transmission line environment simulation. Background technique [0002] Dust weather may cause changes in the electric field around the transmission line, making the corona characteristics of the transmission line worse, and even tripping the line. Therefore, experimenting to simulate the corona characteristics of high-voltage wires in dusty environment has guiding significance for power grid safety. [0003] The traditional sand and dust weather simulation uses large-scale wind tunnel equipment, which covers a large area, cannot be moved, and the experiment cost is high. It cannot meet the requirements of simulating different altitudes and frequent tests. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies of the prior art, and provide a dust weather simulation test s...
