In the testing stage of HEMU-400X(next Korean high speed train) developing project, maximum speed(400 ㎞/h) tests will be conducted. On present and near future conditions of the overhead contact lines, 400㎞/h is over the design speed criteria. The predictions of current collection performance including the percentage loss of contact(arcs level) parameter through dynamic interaction simulation of HEMU-400X maximum speed test run are described in this paper. Various simulations are conducted at the condition of two different contact wire tensions to draw the proper contact wire increasing values in the 400㎞/h test line under the available contact wire tension supporting condition of that line.

This paper aims to review the basic conditions in designing the de-icing system of the loop current type in AGT 3rd rail system. The loop current type is defined as melting ice/frost on the rigid conductor by Joule’s heat generated by large current flowing through rigid conductor. A simulation is more cost-, time- effective means than experiments in reviewing the temperature increase in loop current type of de-icing system. To make simulation program, the theoretical backgrounds were reviewed. In accordance with the established theory, simulation program was written in MS-Excel. To verify the accuracy of developed simulation program, current injection experiments in rigid conductor were conducted. Temperature rises at 1700A, 1500A, 1200A were compared with the program. Two(experiment and program) results were fairly good agreed. With the simulation program, case studies were conducted in various assumed conditions, especially in 2m/s wind condition and in 60 minutes current injection, etc. From simulation case study, we deduced followings; 1) The operation of loop current de-icing system is quite safe up to 1700A-60 minutes current injection condition. 2) 30 minutes before commercial operation is proper for the current injection time 3) To obtain the de-icing effectiveness, it is necessary to inject the 1500A or more.

In this study, the relation between the rotation which are usually caused by the creep of the contact wire, the bar geometry and the forces(wire tensions) for the triangle-shaped distribution bar and straight-shaped one in dependent tensioning device system is reviewed. According to the result, a rotation of distribution bar in triangle-shaped one modifies the distribution of the tensions between the three wires hooked in a distribution bar. On the contrary, a rotation on the straight-shaped one leads to no tension distribution change. Therefore, to use the straight-shaped distribution bar instead of triangle-shaped one is recommended. In addition, the design contents of the distribution bar which will be used in electrification of Gyeongbu line are described in this paper.

The dropper length calculation method about the normal same encumbrance spans is well known independent to whether the pre-sag is given or not. But the dropper length calculation method for the elevating span which consists in the end area of a tensioning section and normally consists with overlaps is not well known. In this study firstly we investigate the dropper length calculation method about the elevating span whether the insulator is contained in or not we also recognize the effect of dropper length due to the change of the take-off point. Secondly we very this calculation method with a catenary sample data and check again with Gyeongbu HSL design data.

The next Korean high speed train development project is started. In testing stage of this project, the 400㎞/h maximum speed test will be conducted. In Korean railway infrastructure conditions the 400㎞/h seems to be a critical speed especially in the aspect of the overhead contact lines. The current collection performance of the 400㎞/h which is predicted by dynamic interaction simulation are described in this paper. To discuss the permissible criteria of contact forces, displacements and percentage contact loss, the French 575㎞/h current collection conditions are simulated. Furthermore, review of the simulation results of the Korean 400㎞/h current collection conditions is conducted through comparison with that of the French 575㎞/h.

A catenary system should be designed to be an uniform elasticity over a span in order to maintain the lowest possible loss of contact between a pantograph and a contact wire. A elasticity disuniformity of a catenary can be regarded as a important design factor used for predicting the current collection performance for a catenary. There are a couple of formulas to calculate elasticity disuniformity of a catenary according to the literature survey. The effectiveness of these formulas is reviewed by performing catenary elasticity and loss of contact analysis for 5 different configurations of catenary systems using a beam element based FEM program, KRRI developed program, and the loss of contact by GASENDO, RTRI developed program, respectively. The results reveals that these formulas are not suitable to predict the current collection performance for a catenary. Therefore, a new formula based on the standard deviation of the elasticity over a span is proposed in this study. The analysis results show that the new formula for an elasticity disuniformity of a catenary is very effective in predicting the current collection performance for a catenary.
