Description
Technical Field
The utility model relates to a track traffic power supply system contact net isolator field, in particular to track traffic contact net isolator equipotential operation platform.
Background
Based on the advantages of energy conservation, environmental protection, convenient travel and promotion of urban economic life development, urban rail transit is rapidly developed in more and more cities, and the requirement on the safety of operation is higher and higher.
Urban rail transit mainly adopts the direct current system of supplying power, and vehicle section/parking area electrification station road area set up the manual isolator that all needs to set up usually. The operating requirement of a manual disconnector is to allow operation without load, but in certain emergency or fault situations may result in accidents where the operator gets electrocuted. Along with the development of urban rail transit construction, the scales of vehicle sections and parking lots are gradually increased, so that the safety problem of operation and maintenance personnel is more obvious.
Any protective measures are not taken in the operation area of the existing manual isolating switch, when the manual isolating switch is in electrified misoperation, the isolating switch is in insulation breakdown and the like, the manual isolating switch operation mechanism can be electrified under the conditions, and therefore the electric shock accident of operators can occur.
Therefore, an urgent need exists for an equipotential operating platform for a manual disconnector of a contact system in rail transit, which can ensure that the potentials of operators of the manual disconnector are consistent under any circumstances, and personal safety accidents such as electric shock hazard cannot occur.
