Description

Electronic bypass unit {AN ELECTRONIC BYPASS UNIT}

 The present invention relates to an electronic bypass unit, and in particular, even if the bulb is disconnected, it is limited to the set voltage (Zener voltage), and when the bulb is replaced, the electronic bypass unit enables permanent use by allowing it to operate normally again. It is about.

The aerodrome lighting 2 of the aerodrome is connected in series as shown in FIG. 1 (a) and is supplied with power by a constant current regulator (CCR) 1.

In the airlighting circuit, when the light bulb 13 is disconnected, a high voltage may be generated on the secondary side of the buried insulated transformer 11, thereby damaging the buried insulated transformer 11.

In addition, when a plurality of light bulbs 13 are connected as shown in FIG. 3, even if only one light bulb 13 is disconnected, the whole is turned off.

In order to prevent this, a film cut out 12 is conventionally used, and the film cut out 12 is short-circuited by a high voltage peak voltage generated when the bulb 13 is disconnected. The voltage rise on the secondary side of the buried type insulation transformer 11 is limited, and the other light bulbs 13 connected in series are normally turned on.

However, since the conventional film cutout 12 is not restored once a short circuit, the bulb 13 must be replaced every time the light bulb 13 is disconnected.

The present invention devised to solve the above problems is limited to the set voltage (Zener voltage) even when the bulb is disconnected, and provides an electronic bypass unit that allows permanent use by operating again when the bulb is replaced. Has its purpose.

The electronic bypass unit of the present invention for achieving the above object is not conducting when the bulb is normally lit, the conduction of the bulb when the bulb is disconnected to prevent the rise of the voltage across the line, when the triac firing The first resistor (R1) and the first capacitor (C1), which absorbs the noise generated in the circuit is connected in parallel with the triac, and when the bulb is lit normally, the triac is not conducted and the bulb is disconnected. The city includes a first to fourteenth zener diode for conducting the triac, a second resistor R2 and a third resistor R3 for controlling the gate current of the triac.

The first to fourteenth Zener diodes ZD1 to ZD14 may vary in quantity and voltage depending on the capacity of the bulb.

The present invention configured as described above is limited to the set voltage (Zener voltage) even when the bulb is disconnected, and when the bulb is replaced, it is possible to use it permanently by operating normally again.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

4 and 5, instead of the film cutout 12 of FIG. 3, it can be seen that the electronic bypass unit 22 of the present invention is connected.

As shown in FIG. 6, the electronic bypass unit 22 of the present invention is not conducting when the light bulb 23 is normally turned on, and when the light bulb 23 is disconnected, the electric bypass unit 22 is turned on to increase the voltage across the line. Triac (TRIAC) to prevent the connection, the first resistor (R1) and the first capacitor (C1) that absorbs the noise generated during the firing of the triac (TRIAC) connected in parallel with the triac (TRIAC) When the light bulb 23 is normally turned on, the triac triac does not conduct, and when the light bulb 23 is disconnected, the first to fourteenth zener diodes conduct the triac triac. ZD1-ZD14, and a second resistor R2 and a third resistor R3 for controlling the gate current of the triac TRIAC.

Referring to the operation of the present invention configured as described in detail as follows.

Zener diodes are connected in parallel through the triac and resistance at both ends of the line, and the zener voltage of the zener diode is set to about 1.5 to 2 times the voltage supplied to the bulb 23 so that the bulb 23 is If it is lit normally, the triac will not conduct.

If the light bulb 23 in FIGS. 4 and 5 is disconnected, a high voltage is generated across the line. In this case, the zener diodes ZD1 to ZD14 of FIG. Flows through the gate to conduct the triac's anode and cathode to prevent the voltage across the line from rising.

In the case of using a normal voltage source, when the triac becomes conductive, both ends of the line short-circuit and high current flows on the input side.In the case of aviation lighting, a current source supplied from a constant current regulator is used. Does not occur.

The number and voltage of the Zener diodes ZD1 to ZD14 may vary according to the capacity of the light bulb 23, and the values are as follows.
