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.
