Abstract
The utility model discloses a one-way conduction device control system of a direct-current traction power supply system. The one-way conduction device control system comprises a one-way conduction device, a diode and a high-speed fuse are in parallel connection at two ends of the insulation junction of the one-way conduction device, a current sensor is serially connected on a circuit of the diode and the fuse, a voltage sensor is parallelly connected on the circuit between the diode and the fuse, disconnected or connected status signals of the fuse are outputted to a monitoring control system via a switch quantity processing module, and the signal outputting portion of the monitoring control system is connected to a power monitoring system. By the above structure, return current of a steel rail can be timely collected and monitored and monitoring data can be uploaded to an automatic monitoring system through a control device, so that a command center can master changes of the return current in real time, failures of the device can be analyzed in real time so as to take measures, convenience and reliability in control are achieved, intelligent control is benefited, and the one-way conduction device control system is of great importance to ensuring safety operation.
Description
Technical field
The utility model relates to the control system of using in a kind of DC traction power-supply system, specifically a kind of DC traction power-supply system device in one-way on state control system.
Background technology
At present domestic in subway (light rail) rail system; some special location of track arranges insulated joint and parallel connection " device in one-way on state "; to reduce existing and sphere of action of protected section stray current; the etching problem of the stray current that reduces protected section to metal pipe line and structure reinforcing bars, has obtained good effect.But because traditional device in one-way on state set-up of control system is unreasonable, make its control very inconvenient, can not in time rail return current electric current be gathered and be monitored and by control setup, monitoring data is uploaded to automatic monitoring system, make command centre can not grasp in real time the variation of back flow current, thus fault that can not real-time analysis equipment taking measures.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly can to data, gathers monitoring in time, controls convenient and reliablely, is beneficial to the intelligent DC traction power-supply system device in one-way on state control system of controlling.
In order to solve the problems of the technologies described above, DC traction power-supply system device in one-way on state control system of the present utility model, comprise device in one-way on state, the insulation knot two ends of device in one-way on state are parallel with diode and quick acting fuse, on the loop of diode and fuse, be serially connected with current sensor, between diode and the loop of fuse, there is the voltage sensor being arranged in parallel, fuse is exported to a monitor control system through a switching value processing module by the disconnection of fuse or on-state signal, the segment signal output of monitor control system is connected in an electric power monitoring system.
Described electric power monitoring system is SCADA system.
The segment signal output of described monitor control system is also connected with RS485 port.
The segment signal output of described monitor control system is also connected with the display unit that fault is shown.
Adopt after above-mentioned structure, between the current sensor being connected in series on loop due to diode and fuse and diode and the loop of fuse, there is the voltage sensor being arranged in parallel, fuse is exported to a monitor control system by the disconnection of fuse or on-state signal, the segment signal output of monitor control system is connected in an electric power monitoring system, thus when guaranteeing that track backflow continues to flow, reduce the rail current of protected section, thereby reduce protected section stray current and leak the electrocorrosion level to structure reinforcing bars and metal pipe line, reduced to greatest extent the leakage of stray current to protecting corrosion and the harm of stray current weak link, reduce the rail potential of protected section simultaneously, guarantee the personal safety of service personnel, it can gather and monitor and by control setup, monitoring data is uploaded to automatic monitoring system rail return current electric current in time, make command centre grasp in real time the variation of back flow current, fault that can real-time analysis equipment is also taken measures, its control is convenient and reliable, be conducive to intelligent control, to ensuring safety, operation is significant.
Accompanying drawing explanation
Fig. 1 is the utility model DC traction power-supply system device in one-way on state control system schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, DC traction power-supply system device in one-way on state control system of the present utility model is described in further detail.
As shown in the figure, DC traction power-supply system device in one-way on state control system of the present utility model, comprise device in one-way on state, the insulation knot two ends of device in one-way on state are parallel with diode and quick acting fuse, on the loop of diode and fuse, be serially connected with current sensor, between diode and the loop of fuse, there is the voltage sensor being arranged in parallel, fuse is exported to a monitor control system through a switching value processing module by the disconnection of fuse or on-state signal, said current sensor also can output to the analog signals of electric current in monitor control system, said voltage sensor also can output to the analog signals of voltage in monitor control system, the segment signal output of monitor control system is connected in an electric power monitoring system, said electric power monitoring system is SCADA system, that is to say that monitor control system can accept and process the switching value of analog quantity and the fuse state of electric current and voltage, and detecting and result signal output power SCADA system.
The segment signal output of further said monitor control system is also connected with RS485 port, can connect other monitoring system by RS485 port thus.
Further the segment signal output of monitor control system is also connected with the display unit that fault is shown.
