Description

A kind of wire icing of transmission line increasing law test unit
Technical field
The utility model belongs to the electrical engineering technical field, relates 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 have caused large-area power outage because icing causes collapse of iron tower, conductor cord disconnection, and the people's production and life consisted of serious threat.
Be effectively to resist the ice and snow disaster, must grasp the icing increasing law of transmission line of electricity under running current and the relation of the meteorologic parameters such as temperature, rainfall, wind speed.Take this increasing law as the basis, in conjunction with the forecast conclusion of the meteorologic parameters such as temperature, rainfall, wind speed, can predict exactly follow-up many days powerline ice-covering growth pattern, for the anti-ice work of electrical network provides information guiding.At present, lack a kind of wire icing of transmission line increasing law test unit on the market, can't obtain a large amount of data by simulation ice-coating test, and then can not grasp the wire icing increasing law.Therefore, need in a hurry exploitation wire icing of transmission line increasing law test unit.
The utility model content
The technical problems to be solved in the utility model is, present situation for present shortage wire icing of transmission line increasing law test unit, designed a kind of wire icing increasing law test unit, utilize this device, can carry out the icing growth test of all kinds of model wires under the belt current condition, sum up the wire icing increasing law, resist ice damage work for electrical network guidance is provided.
Technical solution of the present utility model is, described a kind of wire icing of transmission line increasing law test unit, and referring to Fig. 1, this installs as shown in Figure 1, is comprised of current lifting device 1, regulation and control system 2, thermal detector 3, wire 4 with center pit 11.Wherein said regulation and control system 2 is electrically connected to described current lifting device 1, and described wire 4 is the center pit 11 that round passes described current lifting device 1, and described thermal detector 3 is stacked and placed on the described wire 4.
The wire icing of transmission line increasing law test unit of the present utility model that consists of thus places the central authorities of default phytotron to enable when using.Described 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, so that the icing of Obtaining Accurate wire under various environmental baselines increases data in test.In the said structure of this device, the effect of described current lifting device 1 is to utilize electromagnetic induction to wire 4 up-flows, in conjunction with the operating condition of transmission line of electricity, applies the electric current of a size reasonable for wire 4, and it is conformed to the actual motion size of current of electrical network.Described regulation and control system 2 is used for regulating the electric current of current lifting device 1, reaches the purpose that changes wire 4 size of current.Because it is multiple that the operating condition of wire 4 has, in the actual tests, need to utilize regulation and control system 2 to adjust a plurality of current values, carry out the test of different operating modes.The effect of described thermal detector 3 is the temperature regimes that monitor wire, prevents that conductor temperature is too high, when also monitoring the wire galvanization simultaneously and the temperature difference between the environment.
The beneficial effects of the utility model are:
1), can carry out the icing growth test of wire 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, flexible adjustment;
5), security of operation, to the person and equipment cause danger not.
