Description
Technical Field
The invention relates to the technical field of safety of matched use of a rail transit traction power transformation system, in particular to a wireless transmission passive equipotential display system powered by a distributed power supply.
Background
In the operation of the electrified railway, the power cut, power transmission and electricity test processes of a traction power supply system (including a traction substation, a contact network and the like) are extremely important for the safe operation of the electrified railway, and are closely related to the safety of equipment and personnel. When the traction substation and the contact network are overhauled in a power failure mode, the regulations of operation after power failure, electricity testing and ground wire hanging are required to be followed. In the prior art, the electricity testing operation is usually manually operated, and is completed (whether a power supply line is electrified or not) through a pull rod type electricity testing device which is inconvenient to carry during operation, and in actual operation, each electricity testing of a general-scale substation needs about 5-10 minutes, which is very pity for precious skylight maintenance time. More importantly, under bad weather, the operation of artifical manual electricity of testing also can bring certain danger for operating personnel's safety (for example in rainy and snowy days, cause the original object that does not electrically conduct of power supply line to lead to the electric shock accident because of the emergence electric leakage phenomenon such as rainwater, after the detection personnel contacted original uncharged object). Along with the establishment of a large number of high-speed railways in China, the automation degree of a traction power supply system is higher and higher, and the manual electricity testing operation cannot completely meet the requirements of the current high-speed and safe operation system of the railways, so that a power supply line live passive display device appears in the prior art, the prompt can be visually given when workers are in power failure maintenance, the risk of electric shock of the workers is reduced, and the working efficiency is improved.
At present, the electrified passive display devices applied at home and abroad are classified into a contact type and an induction type according to the working principle and the power supply mode. The advantage of the contact type live passive display device is that no external power supply is needed, but the contact type live passive display device has the following disadvantages: firstly, due to the special structure of the contact sensor, the single-phase ground fault of a power supply at an installation position can be caused when a core rod is broken down or an external insulation flashover is determined, and further the power supply faults of a plurality of power supply circuits are caused; and secondly, when the core rod is combined with the outer shell in an adhesive manner, partial discharge can occur, the size of the overall insulation height limits that the core rod cannot form a charged display above 35kV level, the charged display cannot adapt to outdoor environment operation, and therefore the application of the core rod is greatly limited. When the inductive charged passive display device works, the power supply and the electricity taking method of the inductive charged passive display device is that energy is obtained by cutting a secondary coil through a magnetic field generated by current; the method cannot acquire a power supply signal under the condition that only voltage has no current (such as no-load equipment), so that the method cannot normally work and display fails. The self working driving current is provided by the output end of the capacitive high-voltage sensor which is directly contacted with primary equipment, the provided driving current is larger, and the display of whether the display is electrified or not is obvious; however, the device has the defect of poor anti-interference performance, the signal fluctuates greatly in rainy days, effective work cannot be guaranteed, the capacitive sensor is required to be installed in a matched mode, the structure of the whole device is complex, the cost is increased, and due to the fact that power failure installation is needed, the normal power supply of a line is affected to a certain extent. In the prior art, although the passive electrified display device can display the electrified state of the electrified equipment or the conducting wire in real time on site, the electricity taking mode is single because the electricity is taken through the conducting wire, and the electrified display function cannot work normally due to no electricity on the conducting wire or the equipment or the fault of the passive electrified display device, so that the electrified state of the conducting wire or the electrified equipment cannot be indicated correctly. For example, when the power supply is not powered, the whole equipment is normal, but the whole equipment is powered off, because the display lamp does not display, not only can live people not see the live condition, but also can remote people cannot know the live condition because the remote people cannot receive signals, so that the probability that subsequent operators misjudge and directly contact the power supply line to get an electric shock can be caused. For another example, if the site has electricity, the problem occurs through local display, and because the working personnel cannot know the electrification condition and the remote management party cannot inform the working personnel, the probability that the subsequent operating personnel misjudge and directly contact the power supply line to get an electric shock can be generated. The above-mentioned faults are all related to the high-voltage transmission line, once a problem is not found in time, serious consequences including electric shock to dead people can be caused, so the prior art has great defects.
