Description
Technical field
The utility model belongs to the electrical engineering technical field, relates in particular to a kind of transmission line simulation icing test unit that can apply high voltage and big electric current simultaneously.
Background technology
The safe operation of powerline ice-covering serious threat electric system.China will be the beginning of the year in the end of the year to 2008 in 2007, and the wire breaking and tower falling accident that the southern many provinces and cities in the whole nation cause because of the sleet freezing weather has caused massive losses for people's lives and national wealth.For mechanism and the formation condition of exploring powerline ice-covering; Electric and the mechanical property and the de-icing method of research icing transmission line of electricity, related scientific research mechanism has set up transmission line simulation icing test unit in manual simulation climate laboratory and open-air natural icing research station both at home and abroad.But above-mentioned test unit is when the simulation icing, and general applies high voltage on transmission line of electricity, or only on transmission line of electricity, applies big electric current, perhaps neither applies high voltage, does not also apply big electric current, only on transmission line of electricity, directly carries out not charged experiment.But, both there had been high voltage signal on the ultra-high-tension power transmission line in the actual motion, there is big current signal again.For example the every phase conductor voltage-to-ground in China 220kV transmission line of alternation current is 127kV, and the electric current that flows through every phase conductor also has the hundreds of ampere.Therefore, existing known icing test unit can not be simulated the electrical specification of actual transmission line of electricity, and the virtual condition under existence and the physical environment has the defective than big-difference.
The utility model content
The technical matters that the utility model will solve is to the defective that existing transmission line simulation icing device exists, to develop a kind of transmission line simulation icing test unit.This device is superior to traditional analog powerline ice-covering test unit; Can apply high voltage and big electric current to it simultaneously; Thereby make the electromagnetic nature of treating the very approaching actual transmission line of electricity of icing transmission line of electricity; For deeply disclosing powerline ice-covering mechanism and external insulation characteristic, develop more advanced anti-icing technology and deicing technology test platform is provided.
The technical solution of the utility model is, referring to Fig. 1, said transmission line simulation icing test unit is as shown in Figure 1, is composed in series by isolating transformer 1, first pressure regulator 2, rising current transformer 3, second pressure regulator 4, step-up transformer 5, analog conducting wire 6.The input end of output termination first pressure regulator 2 of wherein said isolating transformer 1.The input end of the output termination rising current transformer 3 of said first pressure regulator 2.The output terminal of said rising current transformer 3 is connected with the termination, two ends of analog conducting wire 6.The input end of the output termination step-up transformer 5 of said second pressure regulator 4.The output terminal of this step-up transformer 5 is connected to analog conducting wire 6.Above-mentioned isolating transformer 1, first pressure regulator 2, rising current transformer 3 are used to produce big electric current; Above-mentioned second pressure regulator 4, step-up transformer 5 are used to produce high voltage.
