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
The present invention relates to a kind of dust and sand weather simulation experiment system for corona test, belong to transmission line of electricity environmental simulation technical field.
Background technology
Electric field changed around dust and sand weather may cause transmission line of electricity, and the corona characteristic of transmission line of electricity is become badly, even line tripping.Therefore, the corona characteristic of high-voltage conducting wires has directive significance to power grid security under the test simulation Sand Dust Environment.
Traditional dust and sand weather simulation application be large tunnel equipment, floor area is large, can not move and experimental expenses high.Do not satisfy simulation Different Altitude, the often requirement of test.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the dust and sand weather that a kind of floor area is little, cost is low, removable, test efficiency is high simulation experiment system is provided.
The technical solution adopted in the present invention is:
Airduct is divided into high-order horizontal segment and low level horizontal segment two parts, is connected by the vertical pipeline section of two elbows and the section of between two parts; Blower fan places the low level horizontal segment porch of airduct, and the supply pipe of dispenser passes into the high-order horizontal segment front end of airduct; Frequency converter connects regulation and control blower fan and dispenser; Annular Round Model PFB places the low level horizontal segment rear portion of airduct; Two air deflectors place respectively reference position and the end of the high-order horizontal segment of airduct.
The low level horizontal segment of described airduct places the bottom of modular support, and high-order horizontal segment places the middle level of modular support, and dispenser places the top layer of modular support.
The supply pipe outlet of described dispenser is positioned at the center of airduct.
Beneficial effect of the present invention is:
The present invention adopts air deflector manufacturing eddy flow to accelerate the dust storm diffusion, has the advantages such as the diffusion of shortening airduct and expansion dust storm coverage; Adopt frequency converter regulation and control blower fan and dispenser, monitor flow control by Annular Round Model PFB, test accuracy is higher; The present invention is the miniaturization of dust storm system, structuring, this device succinct directly perceived, have a very strong mobility.
