Description

technical field [0001] The invention belongs to the technical field of electrical engineering, in particular to an ice-melting test platform for an artificial climate chamber with UHV split wires. Background technique [0002] The icing of conductors will seriously affect the safe and stable operation of the line, especially the UHV line, which has a large transmission capacity, and the unplanned outage of the line will pose a great threat to the stability of the power grid. Conductor ice melting has far-reaching theoretical value and practical significance. UHV split conductors have the characteristics of large number of splits, large conductor cross-sectional area, and large ice-melting current. However, small-scale artificial climate test platforms suitable for small cross-section and non-split conductors are still used at home and abroad to simulate single UHV split conductors. Icing test of root wire. In this type of test, the ice-melting test of UHV split conductors ...
