(From time to time the sections are driven with distinct voltages or frequencies.) The grids could possibly be synchronised on a standard basis, but events may perhaps interrupt synchronisation. It's not a difficulty for DC techniques. AC methods have a certain security implication in that the railway electrification procedure would work as a "Backdoor" connection between distinctive sections, leading to, amongst other things, a piece in the grid de-energised for maintenance being re-energised with the railway substation generating Hazard.
Automation of repetitive duties is simplified by line editing and background mechanisms for storing regularly utilised sequences; this will likely prolong to your scripting language which will choose parameters and variable solutions. A command-line record can be saved, allowing evaluate or repetition of instructions.
An extra concern with AT tools is, if stability weights are attached to both finishes, The full stress length is free to maneuver together the observe. In order to avoid this a midpoint anchor (MPA), near to the centre of the tension duration, restricts motion in the messenger/catenary wire by anchoring line网页版下载 it; the Get in touch with wire and its suspension hangers can move only throughout the constraints on the MPA.
