线型结构物脉冲力除冰器参数优化试验研究
Parameter Optimization Experiment Study of Pulse Force De-icer for Linear Structures
摘要
Abstract
Overhead ground lines,which do not undertake the task of electrical energy transmission,face more serious ice-covering problems.In order to apply the electric pulse de-icing technology to linear structures such as overhead ground lines and to further enhance the effectiveness of this technology,this paper investigates the main factors affecting the effect of pulse action,including the coil structure,the spacing between the coil and the multiplier,and the stroke length of the multiplier.Firstly,this paper proposes to indirectly characterize the de-icing performance of the impulse force de-icers by impulse and energy,and uses the impact pendulum experiment to measure the impulse and energy gen-erated by a single electric pulse under different parameters,and the results show that a coil of 4×0.4 mm can generate larger impulse and energy,and the impulse and energy can be further enhanced by reducing the spacing between the coil and the multiplier and increasing the stroke length of the multiplier.Secondly,based on the insulation and waterproof re-quirements in practical applications,the parameters of the impulse force de-icer for linear structures were optimized,using epoxy resin glue to fix the coil in the coil groove,using insulating paper to insulate the coil from the multiplier,and making a guiding-notch on the multiplier reserved for the spacer.Finally,the simulated ground de-icing test in the multi-functional artificial climate laboratory shows that the parameter-optimised de-icer is able to effectively remove the ice cover under different icing conditions,with the maximum de-icing distance reaching 2.7 m for mixed freezing water,and 1.5 m for rain freezing water.In addition,the de-icing distance of the de-icer after parameter optimisation can reach 3.5 m on the natural icing test platform,it's about 45.8%more than that before optimisation,and further verifies the actual de-icing effect of the optimised de-icer.These research results can provide new theoretical basis and practical reference for the de-icing technology of ground lines and other linear structures.关键词
