Description
Technical field
The invention belongs to the electrical engineering technical field, relate in particular to a kind of wire icing of transmission line increasing law test unit.
Background technology
The safe and stable operation of electrical network has been arrived in the wire icing of transmission line serious threat.In southern area ice damage in 2008, many transmission lines of electricity collapse because of icing causes iron tower, conductor cord disconnection, have caused large-area power outage, and the people's production and life constituted serious threat.
Be effectively to resist the ice and snow disaster, must grasp the relation of meteorologic parameters such as icing increasing law and the temperature of transmission line of electricity under running current, rainfall, wind speed.Be the basis with this increasing law,, can predict follow-up many days powerline ice-covering growth pattern exactly, for the anti-ice work of electrical network provides information guiding in conjunction with the forecast conclusion of meteorologic parameters such as temperature, rainfall, wind speed.At present, lack a kind of wire icing of transmission line increasing law test unit on the market, can't obtain lot of data through the test of simulation icing, and then can not grasp the wire icing increasing law.Therefore, need exploitation wire icing of transmission line increasing law test unit in a hurry.
Summary of the invention
The technical matters that the present invention will solve is; Present situation to present shortage wire icing of transmission line increasing law test unit; Designed a kind of wire icing increasing law test unit, utilized this device, can carry out the icing of all kinds of model leads under the belt current condition and increase test; Sum up the wire icing increasing law, resist ice damage work for electrical network guidance is provided.
Technical solution of the present invention is, said a kind of wire icing of transmission line increasing law test unit, and referring to Fig. 1, this device is as shown in Figure 1, is made up of the current lifting device that has center pit 11 1, regulation and control system 2, thermal detector 3, lead 4.Wherein said regulation and control system 2 is electrically connected to said current lifting device 1, and said lead 4 is the center pit 11 that round passes said current lifting device 1, and said thermal detector 3 is stacked and placed on the said lead 4.
The wire icing of transmission line increasing law test unit of the present invention that constitutes thus places the central authorities of preset phytotron to launch when using.Said phytotron should be one can simulate all kinds of natural meteorological conditions change environment temperature, rainfall and wind speed, meets the phytotron of the universal standard, increases data so that accurately obtain in test the icing of lead under various environmental baselines.In the said structure of this device, the effect of said current lifting device 1 is to utilize electromagnetic induction to give lead 4 up-flows, in conjunction with the operating condition of transmission line of electricity, applies the electric current of a size reasonable for lead 4, and it is conformed to the actual motion size of current of electrical network.Said regulation and control system 2 is used for regulating the electric current of current lifting device 1, reaches the purpose that changes lead 4 size of current.Because it is multiple that the operating condition of lead 4 has, in the actual tests, need utilize a plurality of current values of regulation and control system 2 adjustment, carry out the test of different operating modes.The effect of said thermal detector 3 is the temperature regimes of keeping watch on lead, prevents that conductor temperature is too high, when also keeping watch on the lead galvanization simultaneously and the temperature difference between the environment.
The invention has the beneficial effects as follows:
1), can carry out the icing growth test of lead under running current, for grasp wire icing increasing law is laid a solid foundation;
2), the size of temperature, rainfall and the wind speed of flexibly changing environment, simulate all kinds of natural conditions icing.
3), simple in structure, easy to operate;
4), can realize the automatic control of current in wire size, regulate flexibly;
5), security of operation, to the person and equipment do not cause danger.
