Description of drawings:

Fig. 1 is the utility model background technology accompanying drawing;

Fig. 2 is the utility model sketch map; Wherein:

1. relay tip; 2. electric current mutual inductance circuit.

Embodiment:

Among Fig. 1, specify to background technology:

The LED lamp is widely used in other field, but because the railway system is higher to the reliability requirement of fail safe and signal, and technology innovation is conservative relatively, when more changing the bulb, its control, warning circuit do not allow to change easily.Because the monitoring relay DJ that lights a lamp of transformer front end is a current relay, requirement must electric current greater than the situation of 100mA (130mA, the relay model is different) under relay could move.And this just requires the power of lamp end to consume 25W at least.

The design of present most of LED signal lamp all is to adopt directly replacing bulb is become the LED lamp; The efficient height because the LED lamp is given out light; The power of the LED lamp of same illumination has only 5-8W; Other power need join mode such as resistance by string (perhaps also) and convert thermal energy consumption to and fall so, and the lamp terminal circuit active loss of design still is 25W (perhaps more) like this, does not reach energy-saving effect.And, make the in-house temperature rise of signal lamp usually more than 30-50 ℃ because power conversion becomes heat loss, and like this, when LED can't work long hours in the summer of sweltering heat.High temperature is very big to the effect on service life of its LED.The LED semaphore lamp that existing mode designs does not give full play of the energy-conservation and long-lived characteristics of LED.

The on-the-spot lamp circuit that uses now, the AC220V of station power supply panel output, the series connection coil of monitoring relay DJ of lighting a lamp on the single line is in output is arrived at a station then or the interval transformer BX34 that lights a lamp.The transformer BX34 that lights a lamp is installed in the chamber below the inner perhaps semaphore of semaphore.BX34 transformer rated power is 34W, input 180-220V, the transformer of output 12-15.This transformer back-end circuit is all inner at semaphore.The secondary side output single line serial connection filament transfer relay DZJ of BX34 transformer and the serial connection loop of main filament; This root line also is connected in series the loop of paranema series connection of one group of normally closed contact and the filament of filament transfer relay DZJ; In other words, lamp changes the coil series filament master's silk of relay filament transfer relay DZJ and the filament paranema parallel connection of the normally closed contact series connection that lamp changes relay filament transfer relay DZJ.The single line in addition of the public termination BX34 transformer of filament.After being connected like this sent electricity; The 12V electricity loads on two filaments at powered on moment simultaneously; But the main silk loop of connecting with coil presents perception, and electric current has the process that increases gradually, but the paranema of connecting with normally closed contact K1 is because the minimum characteristic of cold silk resistance of bulb; Electric current can impact paranema, and the while also requires the normally closed contact K1 of filament transfer relay DZJ that the load capacity of big electric current can be arranged.By the time the electric current on the main silk be increased to filament transfer relay DZJ can operate as normal after, filament transfer relay DZJ picks up, normally closed contact breaks off, break in the paranema loop.If in the operate as normal, fracture of wire appears in main silk, and the wire loop of filament transfer relay DZJ is broken, and filament transfer relay DZJ discharges, and normally closed contact K1 is closed, links up the paranema loop and makes paranema luminous.Require main silk to paranema change-over time＜0.1 second.

To the utility model, in conjunction with Fig. 2:

Power＜the 8W of LED lamp itself; All the other power through at transformer front end parallel connection safety electric capacity carrying out reactive power compensation consumption, when LED lights, when electric current is maintained in the brightness that electric current reaches the requirement light intensity; Electric current mutual inductance circuit control relay J action; Relay tip 1 is connected, and safety electric capacity discharges and recharges, and so just makes the meritorious consumption part of original circuit be converted into reactive power consumption; Guaranteed not reduce through the electric current of the monitoring relay DJ that lights a lamp, the feasible monitoring relay DJ that lights a lamp can reliably working.The LED lamp breaks down, and the electric current relay that can not meet the demands then is failure to actuate, and relay tip 1 is not closed, and electric current at this moment can guarantee that DJ reliably falls.Resistance in the circuit only plays metering function, is to be used for the protection relay contact not burnt out by instantaneous large-current sparking or reduce its useful life.Because safety electric capacity presented open circuit characteristic when losing efficacy, can not make circuit short circuit occur, so the design is safe.

Following circuit is the modification that combines real circuit to make.AC220V exports from power supply panel; The single line process is lit a lamp behind the monitoring relay DJ; Output to outdoor with other single line; To on-the-spot semaphore, the BX34 of the original usefulness transformer of lighting a lamp changes 10W into by 34W in the signaling gear through several kilometers circuits, transformer input parallel connection relay tip 1 and resistance R series connection again with the parallelly connected circuit that is in series of two safety capacitor C 1 and C2.The transformer of lighting a lamp changes 160V-220V output 13V-18V into, and power is 10W.The 13V of the transformer of lighting a lamp output supplies with LED lamp power supply, and LED lamp inside detects whether king light is damaged, and automatically switches to secondary lamp in the king light fault.The major-minor lamp all is a plurality of one group high-power wick.Crosstalk stream mutual inductance circuit on the lamp loop; Judge whether operate as normal of lamp by current value; As long as lamp is normally lighted, instrument transformer drives relay J work, makes the series loop work of the normal opened contact and the resistance capacitance of front end; Make consume reactive power, reactive power consumption with meritorious that consume with make the monitoring relay DJ that lights a lamp can keep normal operating state.

The LED lamp adopts a plurality of lamp pearls, is divided into two groups, also is the major-minor structure, and is identical with bulb reserve principle, but there is not cold shock in LED, so the major-minor lamp life-span is identical, and behind the king light fault alarm, secondary lamp can operate as normal come to change up to the staff fully.Solved the unborn potential risk of bulb.

The number of the parallel connection of said safety electric capacity does not cause restriction to the utility model.

Electric current mutual inductance circuit 2 can make the action of relay or electronic switch, and the element of used is relay or electronic switch or other similar functions does not cause restriction to the utility model.

Because the utility model takes non exhaustive mode to describe, therefore described content does not cause restriction to the practical implementation of the utility model, and similarly execution mode also belongs to the protection range of the utility model.
