Embodiment Construction

[0018] In the following description, referring to the distance between two parts "in a straight line" means that physical obstacles between the two parts are not considered. Reference to the distance between two points measured along the insulating wall means the shortest curvilinear distance along the surface of the insulating wall passing through the two points. The route corresponding to the shortest distance is called the "creepage path", equivalent to the meaning of "creepage path" in the field of electrical insulators.

[0019] figure 1 A rail vehicle 99 of the present invention is shown in . The rail vehicle 99 includes a partially open downstream upper portion 100A and a covered upstream upper portion 100B.

[0020] The rail vehicle 99 includes an electrically conductive roof 102 (also referred to as a canopy) extending generally horizontally below, inter alia, a downstream upper portion 100A and an upstream upper portion 100B of the rail vehicle 99 . The roof 102 f...

Abstract

The invention relates to a railway vehicle and a method for manufacturing same. The railway vehicle comprises first and second electric conductors (102, 106) between which over 5000 volt of potential difference is generated during running of the railway vehicle; and insulation walls (124, 126) which is distant from at least one of the conductors and has first points (P1, P2) for approaching the first conductor (106) and second points (P'1, P'2) for approaching the second conductor (102). At least one ripple is arranged between the first points and the second points, which are distanced at a predetermined interval (D) along the insulation walls (124, 126) to prevent generation of electric arc between the first and second electric conductors.

Description

technical field [0001] The invention relates to a part of a rail vehicle, a rail vehicle and a method of manufacturing said part of a rail vehicle. Background technique [0002] In general, the roof of all trains or locomotives has a clear part, i.e. not covered by a fairing, to accommodate all high voltage roof equipment of the rail vehicle, such as pantographs, high voltage circuit breakers, Different circuit breakers, protection systems (such as lightning arresters), etc. configured for supply or ground circuits. [0003] High voltage equipment usually includes exposed electrical conductors (such as contacts) that can generate a potential difference of more than 5000 volts between the electrical conductors or with respect to the roof of the vehicle when the rail vehicle is in operation, and the roof is usually regarded as an electrical ground conductor. [0004] The hollow part of the roof is surrounded by substantially vertical base sides and upstream and downstream by ...
