Abstract
A railway signal power instant current interruption protection device relates to a protection devices of railway signal power interruption, which guarantees the power supply status of the power supply system to the loads is not changed, keep the continuity of the power supply frequency, phases and voltage amplitudes unchanged and always keep the signal devices under normal operation conditions when the two power supplies of signal device power system (line I and line II) convert or instantly interrupts. This device is applicable to the power supply system that the loads have higher requirements for power supply frequency, phases and continuity of voltage amplitudes during the current interruption and especially to the railway signal power supply system.
Description
Technical field
The utility model relates to a kind of protection railway signal power supply power cutoff device, and load is specially adapted to railway signal power supply system to frequency of supply, phase place, the demanding power-supply system of voltage magnitude continuity when being applicable to outage.
Background technology
Railway signal power supply instant cut-off safeguard is during conversion of signalling arrangement power-supply system two-way (I road and II road) power supply or instant cut-off, be used to guarantee that power-supply system gives the power supply state of load constant, the continuity that keeps frequency of supply, phase place, voltage magnitude, make signalling arrangement be in normal operating conditions, guarantee railway operation safety.
At present, instant cut-off is taking place or is carrying out power-supply system two-way (I road and II road) the power supply transition period in railway signals equipment, since moment after not having electricity, cut off the power supply and restoring electricity frequency of supply, phase place, voltage magnitude and can't keep continuous originally, cause signalling arrangement operating states such as track circuit, semaphore, turn-out track equipment, interlock circuit to change, cause the signalling arrangement fault, directly influence railway operation safety, train running on scheduled time and conevying efficiency.Be technical barrier of not resolving and the potential safety hazard that railway signals equipment existed since the utilization midium or long term.
Summary of the invention
Instant cut-off is taking place or carrying out power-supply system two-way (I road and II road) the power supply transition period in order to overcome present signalling arrangement, the track circuit that causes, semaphore, turn-out track equipment, the variation that signalling arrangement operating states such as interlock circuit take place, the utility model provides a kind of railway signal power supply instant cut-off safeguard, the auxiliary power supply module of safeguard is devoted oneself to work when outage, provide and cut off the power supply before the frequency of AC power of output, the phase angle, the corresponding to power supply of voltage magnitude, do not interrupt output AC power source continuously, the signalling arrangement operating state is not changed; After restoring electricity, after frequency, phase angle, the voltage magnitude of the AC power of ac power frequency, phase place, the voltage magnitude that the adjustment of auxiliary power supply module provides and the back input that restores electricity is consistent, revert to by input ac power and power, the auxiliary power supply module is deactivated, holding frequency, phase place, voltage magnitude do not interrupt continuously, and the signalling arrangement operating state is not still changed.Promptly accomplish seamless input and seamless withdrawing from, avoid signalling arrangement to break down, guaranteed railway operation safety.
The scheme that the utility model solves this technical problem is: get involved railway signal power supply instant cut-off safeguard between signalling arrangement power-supply system two-way (I road and II road) introducing and signal power source equipment.Behind power connection, railway signal power supply instant cut-off safeguard is exported to the signal power source power devices to importing after the AC power that changes in the scope up to specification detects, adjusts, power-supply device is exported corresponding power supply by unequally loaded with electric standard, signalling arrangement enters normal operating conditions, and the testing circuit of railway signal power supply instant cut-off safeguard carries out real-time tracking to the input power supply status and detects.Parameters such as the input supply frequency that provides by the testing circuit of railway signal power supply instant cut-off safeguard when outage takes place, phase place, voltage magnitude, driving the auxiliary power supply module devotes oneself to work, provide and cut off the power supply before the corresponding to power supply of frequency, phase angle, voltage magnitude of AC power of output, finish and do not interrupt output AC power source continuously; After restoring electricity, testing circuit detects, compares frequency, phase angle, the voltage magnitude of the AC power that the AC power and the work of auxiliary power supply module of input are exported, in a short period of time frequency, phase angle, the voltage magnitude of the AC power of auxiliary power supply module output are adjusted, when with the frequency, phase place of the AC power of input, when voltage magnitude is consistent, control auxiliary power supply module is deactivated, revert to by the input ac power power supply, continue to keep out-put supply frequency, phase place, voltage magnitude not to interrupt continuously.
Outstanding effect of the present utility model is, during conversion of signalling arrangement power-supply system two-way (I road and II road) power supply or instant cut-off, because the intervention of railway signal power supply instant cut-off safeguard, the continuity that has kept frequency of supply, phase place, voltage magnitude, make signalling arrangement be in normal operating conditions all the time, avoid the signalling arrangement momentary status to change the fault that causes, improved railway signals equipment traffic safety supportability.
