Description
Technical field
The invention belongs to analog machine technical fields, are related to a kind of simulation ice-coating load device.
Background technique
One of an important factor for coated by ice of overhead power transmission line is threat transmission line safety.In recent years, due to serious regelation
And the Frequent Accidents for causing electric power pylon to collapse, therefrom caused by directly or indirectly economic loss it is huge.Pass through ice coating load
Simulation test can help people to understand the situation of change of tension, arc sag of coating ice falling front and back overhead transmission line etc. and cover
Ice falls off the impact caused by conducting wire and shaft tower, to take the effective precautionary measures.Due to having for coated by ice of overhead power transmission line
It closes research to be still in the primary stage, experimental rig used needs to continuously improve there is also many defects.
Chinese Patent Application No. 200920313473.1 discloses a kind of " suspension device for icing simulation verification of transmission conductor ",
The sandbag of simulation ice-coating is suspended on aerial condutor by the device using nylon rope, electric furnace heating wire is connected on nylon rope, using electricity
The method realization of furnace silk fever fusing nylon rope deices simulation.This apparatus structure is complicated, energy consumption is high, poor reliability, Buddhist nun used
The fusing speed of dragon rope cannot be reused slowly and after fusing, and make troubles, greatly reduce to ice coating load simulated test
Experiment work efficiency.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of structures to be simple and convenient to operate, reliability and
The high simulation ice-coating load device of test efficiency.
Problem of the present invention is realized with following technical proposals:
A kind of simulation ice-coating load device is made of U-bolt, horizontal iron plate, electromagnet and mass, the U-shaped spiral shell
Bolt is straddled on aerial condutor and is fixedly connected with horizontal iron plate below, and the electromagnet is located at the lower section of horizontal iron plate simultaneously
It is connect by magnetic force with horizontal iron plate, the lower part of electromagnet is fixedly connected with mass.
Above-mentioned simulation ice-coating load device, the horizontal iron plate are in rectangle, and the U-bolt is arranged two, and connects respectively
It is connected to the both ends of horizontal iron plate.
Above-mentioned simulation ice-coating load device, the electromagnet use sucked type electromagnet.
Compared with prior art, the invention has the following beneficial technical effects:
The mass of simulation ice-coating is suspended on aerial condutor by the present invention using the magnetic force of electromagnet, not only structure letter
Single, high reliablity, and it is easy for installation, reproducible, mass falling speed is fast, be greatly improved overhead line ice coating load mould
The working efficiency of quasi- test.
Detailed description of the invention
Fig. 1 the structural representation of present invention.
Specific embodiment
As shown in Figure 1, the present invention includes two U-bolts 2, horizontal iron plate 3, electromagnet 4 and mass 5, U bolt 2
It straddles on aerial condutor 1, bipod passes through horizontal iron plate 3 and is fixed together by nut with horizontal iron plate 3.Electromagnet 4
By magnetic-adsorption in the lower section of horizontal iron plate 3, electromagnet 4 is fixedly connected with mass 5 below.
Specifically, the horizontal iron plate 3 is in rectangle, the U-bolt 2 is arranged two, and is connected to horizontal iron plate 3
Both ends.
The electromagnet 4 uses sucked type electromagnet.
The shape of the mass 5 is rectangular, adsorption capacity of the weight less than electromagnet 4.
The present invention can not only transmission line simulation ice coating state, additionally it is possible to the ice-shedding of overhead line simulated,
Specifically used method are as follows: horizontal iron plate 3 is fixed on aerial condutor 1 with two U-bolts 2 first, and by electromagnet 4 with match
Weight 5 is fixed together, and then connects the power supply of electromagnet 4, is allowed to be adsorbed in the lower section of horizontal iron plate 3, transmission line simulation
Ice coating state；Then the power supply of tripping magnet 4 makes the electromagnetic force between electromagnet 4 and horizontal iron plate 3 disappear, 4 He of electromagnet
Mass 5 falls together, simulates aerial condutor coating ice falling and the thus change of caused overhead transmission line tension, arc sag etc.
Change.Aerial condutor jump height and tension variation situation are recorded during the test, analyze coating ice falling pair using the data obtained
The percussion of conducting wire and shaft tower, analog reslt and Numerical Simulation Results are compared, to verify the standard of analysis model
True property.Several device for icing load simulation test can be set when test on aerial condutor 1, to simulate in overhead transmission line
The variation of several node icing while fall off caused tension, arc sag etc..
