Description
Technical field
This utility model relates to the safety monitoring technology field of railway signal, it particularly relates to the safety monitoring alarm control unit of a kind of alternative railway signal filament relay.
Background technology
Existing railway signal lamp circuit is dependent on filament relay in order to ensure safety supervision semaphore duty, the excitation of this relay, represent the normal lighting of semaphore；The release of this relay, represents that semaphore is turned off the light.Short circuit protection is dependent on 0.5A fuse or chopper ensures.As shown in Figure 2, indoor signal lighting control circuit uses alternating current 220V power supply through overcurrent fuse, filament monitoring relay DJ, the output of signaling point lamp control circuit, through outside cable, deliver to transformator BXU, BXL, BXH respectively, through being depressurized to 12V, for amber light U, green light L, the red light H of 12V/25W.Owing to railway signal needs the distance controlled to reach 15 kilometers, therefore there is following major security risk:
1, when signal lighting transformator (or lighting unit) secondary circuit short-circuit of semaphore, even if semaphore is close together, the most hundreds of rice, 0.5A fuse blows or air-break can not be made to disconnect；As long as interval semaphore distance about 10 km, even if cable direct short-circuit at semaphore (short circuit of equivalent signal lighting primary), fuse blows or air-break can not be made to disconnect.Now, semaphore is in the state of turning off the light, and indoor filament relay is still at excited state, and this will bring the potential safety hazards such as signal upgrading or burning apparatus.
2, it is not suitable with current technology development, especially to LED signal machine, there is the most serious safety problem.
(1) electric current when electric current during LED signal machine short trouble and normal work is more or less the same, it is impossible to make fuse blows or air-break disconnect.
(2) being located at outdoor LED signal machine for monitoring device and cannot accomplish fault-safety principle, mainly short circuit safeguard function is the most complete.Such as signal lighting primary short circuit, secondary short circuited, DC source short circuit, monitoring device power supply short circuit etc., it is impossible to make filament relay reliably fall, cause signal to upgrade and burn filament relay and lighting unit.It addition, only partial short circuit safeguard function does not meets fail-safe principle yet: when just losing safeguard function after related device fault, and this fault can not and alarm, therefore must take into fault accumulation.
(3) the operating current of filament relay does not mates with LED signal machine source current.The most several watts of the light source power of LED signal machine, for using the LED signal machine of alternating current 220V system, its electric current about about 50mA, far below the 140mA of 100mA and JZXC-16/16 of the operating current of filament relay: JZXC-H18.In order to make filament relay normally to work, mostly have employed a prestowage resistance in parallel.This cannot meet the requirement of fail-safe: turns off the light when light source open circuit, filament relay can be made to be maintained at excited state by the electric current of prestowage resistance, on the one hand bring hidden danger to safety, on the other hand make function energy-conservation for LED not play.
LED signal machine due to its electronic device more, the probability of the fault that is short-circuited be much larger than electric filament lamp semaphore.Therefore, the protection of above short trouble is the most prominent to the contradiction of LED signal machine.
Itself there is fatal defects in 3, currently used AX type filament relay, does not reaches N class and C class relay standard, it is impossible to protection contact adhesion.
(1) it is provided without the mechanism of forced guiding contact.
When one group of normally opened contact that should not close still closes, it cannot be guaranteed that all dynamic circuit breaker contacts do not close in structure, vice versa.Make dynamic circuit breaker contact can not become secure side.
(2) contactor material is provided without non-weldable material, and is provided without contact series connection or other safeguard procedures in circuit.
(3) release factor is low by only 40 ~ 57%, is unfavorable for improving security control distance, i.e. has the command range of " fracture of wire inspection " function.
On circuit, the excitation of filament relay is to represent that semaphore light source is normally lighted, otherwise represents semaphore light source " fracture of wire ", state of i.e. turning off the light.When semaphore is distant, it is desirable to the no-load current < release current of filament relay of leakage current+semaphore between the line of cable.
4, the outdoor shared a pair alarm cable line of every bottle-neck section signal trouble warning message transmits, as shown in Figure 2.Typically can only determine it is which throat for fault location, if to navigate to the lamp position of certain semaphore, need to increase code-emitting equipment on every frame semaphore each lamp position, indoor add warning exchange.Not only equipment is various, and warning signaling fault likely affects the lighting of semaphore or affects the warning of whole bottle-neck section at one.
