Abstract
The utility model relates to a transmission tower side needle lightning protection test device comprising a landform simulation bench, test towers, side needles and an impulse voltage generator for simulating a lightning stroke. The test towers are arranged on the landform simulation bench, and each side needle is connected to the top portion of each test tower by an adjusting seat. Compared with the prior art, the transmission tower side needle lightning protection test device simulates geomorphic features under different circumstances by arranging the landform simulation bench, so that test conditions are more close to real circumstances, and accuracy of tests is improved; and lightening protection effects under different circumstances can be tested and better test results can be obtained by simultaneously arranging a plurality of test towers and adjusting angles of side needles through adjusting seats.
Description
Technical field
The utility model relates to a kind of test unit, especially relates to a kind of transmission tower side pin lightning test device.
Background technology
Thunderstorm refers to that " because the local storm with lightening activity and showery precipitation that strong cumulonimbus causes, thunderstorm is generally with the Small and Medium Sized synoptic process of the multiple weather phenomena such as hail, strong wind and thunder and lightning, is one of common and great weather disaster in China summer.In general, the large scale environmental baseline that the formation of thunderstorm and development need are favourable.Because specific large scale environment can provide the energy, trigger condition and the organization mechanism of strong convective weather genesis, also can provide the unstable mechanism of the restriction basic flow field that Convective Weather System moves and the development of strong weather.
The generation of Lightning Disaster is relevant with the configuration that ground dodges intensity, amplitude of lightning current characteristic, topography and geomorphology, system running state, thunder And Lightning Preventive Measures.For concrete transmission line of electricity, owing to being subject to the impact of factors, the occurrence degree of actual track lightning stroke trip not exclusively dodges the distribution of density with being equal to.Transmission line caused by lightning strike its distinctive feature arranged, be subject to the impact of design dielectric level itself, only dodges on the ground of some current amplitude section and just can cause trip accident, and different its extent of injury of lightning current of amplitude is also different.In addition, electric network thunderstorm damage causes that the influence factor of line tripping generation is also relevant with the factors such as geology topography and landform character, network system running status and line thunder protection measure of locality.At present, transmission line of electricity can adopt the mode that installs the side pin additional for the protection of thunder and lightning, but how installing the lightning-arrest effect that can reach best additional but requires study.
The utility model content
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of intuitively, transmission tower side pin lightning test device easily.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of transmission tower side pin lightning test device, comprise terrain simulation platform, test shaft tower, side pin and the impulse voltage generator that is used for the simulation thunderbolt, described test shaft tower is located on the terrain simulation platform, and described side pin is connected to the top of test shaft tower by adjustment seat.
Described adjustment seat is provided with rotating mechanism, by regulating this rotating mechanism, so that the side pin has different angles from surface level.
Described test shaft tower is provided with at least 3, and each test shaft tower is provided with the side pin horizontal by different angles.
Compared with prior art, the utility model is simulated morphologic characteristics under the varying environment by the terrain simulation platform is set, so that test condition and actual environment are more approaching, improves the accuracy of test; By a plurality of test shaft towers are set simultaneously, and adjust the angle of side pin by adjustment seat, thereby measure the lightning-arrest effect under the different situations, reach and test preferably effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of transmission tower side pin lightning test device comprises terrain simulation platform 1, test shaft tower 2, side pin 3 and the impulse voltage generator 4 that is used for the simulation thunderbolt.Terrain simulation platform 1 is for the landforms of simulating various reality, test shaft tower 2 is provided with 3, be erected at each position on the terrain simulation platform 1, side pin 3 is connected to the top of test shaft tower 2 by adjustment seat, be provided with rotating mechanism in adjustment seat, by regulating this rotating mechanism, so that the side pin has different angles from surface level.Side pin on each test shaft tower can arrange different angles, so that carry out simultaneously the test of multiple situation.Impulse voltage generator 4 is arranged on outside the certain distance, sends surge voltage, simulates lightning stroke process.
