Description
Technical field
The utility model relates to a kind of railway signal lamp conversion device, particularly exchanges filament conversion focus-fixing disc.
Background technology
Original traffic light system pattern is: major and minor filament is equipped with in signal lamp inside, main silk work during normal lighting, and after main silk works a period of time fracture of wire, light paranema by lighting unit conversion, and carry out stubble warning device, signalman more changes the bulb and fixes a breakdown.
Along with increasing of the strict of upper track management system and Wayside signal of growing up, the work more changed the bulb becomes all the more difficulty.Such as: at 4:00 AM, there is a frame semaphore fracture of wire in interval, if electricity business section regulation fracture of wire just must be changed immediately, so first signalman will register main points, then walking several kilometers goes to the position of fault more to change the bulb, not only result is " assume responsibility for responsibility but also take artificial ".If more changed the bulb at skylight point after electricity business section regulation fracture of wire, although registration can be solved will put problem, there is the possibility of turning off the light and stopping, so replacing bulb problem becomes increasingly conspicuous.
A lot of stations section all carries out bulb periodic replacement now, and uses twin-lamp socket in a large number, to reduce the generation of fault of turning off the light.But due to bulb life can not reach 100% qualified, so filament failure (about 5%) also can be there is during regularly replacing.And the object of twin-lamp socket just extends the life-span of spare heater and increases reliability.Along with the speed of a motor vehicle is high, large the formed upper track management system of flow strict, although above-mentioned measure effectively can reduce fault of turning off the light, the problems such as brought personal security, labour intensity that temporarily change the bulb can not be solved well.

Detailed description of the invention
See accompanying drawing, a kind of interchange filament conversion focus-fixing disc, comprise lamp socket 1, king light room 2 and secondary lamp 3, lamp socket 1 is provided with king light room 2 and secondary lamp 3, is provided with main filament 4 and auxiliary filament 5 in king light room 2, and the distance of main filament 4 and auxiliary filament 5 is 3 ~ 4 millimeters.Converting unit 6 is provided with in bottom lamp socket 1, converting unit 6 comprises relay 7, current transformer 8, diode 9, rectifier bridge 10, tantalum electric capacity 11, one end, main limit of current transformer 8 connects the secondary limit of the transformer of lighting unit, other end auxiliary connection filament 5, the secondary limit of current transformer 8 connects the two ends of rectifier bridge 10, the another two ends parallel diode 9 of rectifier bridge 10, relay 7 coil and tantalum electric capacity 11, secondary lamp 3 one end is connected with the common port of main filament 4 and auxiliary filament 5, and the other end connects the secondary limit of the transformer of lighting unit by relay 7.Main filament is connected with the filament transfer relay J on lighting unit with auxiliary filament, and secondary lamp is connected with the relay J 1 on lamp socket internal transformation units.In Fig. 4, first half section is lighting unit circuit diagram, and the second half section, for exchanging filament conversion focus-fixing disc circuit, realizes exchanging filament burn out conversion by converting unit.
The course of work of the present utility model: during normal lighting, the main filament 4 of king light room 2 is lighted; When main filament 4 fracture of wire, be transformed into auxiliary filament 5 by the converting unit of lighting unit inside, and reported to the police by original warning circuit; After auxiliary filament 5 fracture of wire, be transformed into secondary lamp 3 by exchanging the converting unit of filament conversion focus-fixing disc lamp group inside, and reported to the police by original warning circuit secondary by supporting lighting unit or carry out stubble warning device by microcomputer monitoring.
Specific as follows:
When signal lamp first time fracture of wire (main filament 4 fracture of wire turns auxiliary filament 5), do not spend replacing bulb, because also have secondary lamp 3 as subsequent use, can not be formed and turn off the light, can wait during the point of skylight and go again to change, so just can solve the problem of personal security and labour intensity preferably.
By improve stent size in king light room 2 by auxiliary filament 5 to main filament 4 apart from strengthening (being increased to 3mm by 2mm), the percentage in more than 200 hours life-spans has brought up to 90% by 50%.
