Abstract
Disclosed is a high-pressure sodium lamp electronic trigger, besides comprising a resonant circuit composed of a capacitor, a high-frequency transformer, and a silicon controlled rectifier(SCR), the circuit thereof also includes a protection circuit which is in parallel connection with the resonator circuit. The protection circuit includes a relay and a bridge rectifier. The utility model solves the problem in the prior art that the capacitor and thyristor are easy to be broke-down, and the low-voltage can not work, thereby being a electronic trigger for high-pressure sodium lamp.
Description
[technical field]
The utility model is a kind of electronic trigger that is used for high-pressure sodium lamp, particularly its circuit arrangement.
[background technology]
High-pressure sodium lamp electronic trigger now commonly used has following deficiency: 1, when external voltage produces fluctuation or electrical network when disturbing pulse occurring, be easy to electric capacity and controllable silicon are punctured; 2, during no power, because electronic trigger is connected in parallel on the electrical network, the static on the electrical network or other induced voltage reach one regularly, also electric capacity and controllable silicon can be punctured; 3, when low-voltage, can not work; When 4, electric capacity is breakdown, serious heating can be occurred, fire may be caused.
The purpose of this utility model is to design a kind of high-pressure sodium lamp electronic trigger with protective circuit.
[summary of the invention]
Circuit of the present utility model divides two parts, and first is the resonant tank that main element is formed by electric capacity, high frequency transformer, controllable silicon, can produce high voltage pulse; Another part is the protective circuit that main element is formed by relay, rectifier bridge, and protective circuit is connected in parallel on the resonant tank.Hook of the present utility model and wiring board are with epoxy encapsulation in the enclosure.
After the utility model was finished and started sodium vapor lamp, the contact of its repeat circuit discharged, and made the utility model break away from big electrical network automatically, and controllable silicon and electric capacity can not burnt out, and have protected circuit preferably; Because the contact of relay disconnects, the resonance cut-in voltage can be lower than national standard, thereby high-pressure sodium lamp also can be worked under low-voltage again.
[description of drawings]
Fig. 1: embodiment front view.
Fig. 2: embodiment circuit theory diagrams.
The circuit of present embodiment divides two parts, and first is by capacitor C
1, high frequency transformer HL
2, controllable silicon CTR
3Resonant tank for main element is formed can produce high voltage pulse; The protective circuit that another part is made up of for main element relay 4, rectifier bridge 5 also is provided with fuse RD in the protective circuit
5With dropping resistor R
6, protective circuit is connected in parallel on the resonant tank.
Present embodiment and high-pressure sodium lamp 7 are connected in parallel on the big electrical network, after the energising, relay 4 normally open contact K
8Adhesive, resonant tank work produces high voltage pulse high-pressure sodium lamp 7 is punctured, high-pressure sodium lamp 7 work, at this moment below high-pressure sodium lamp 7 two ends pressure drop to 20 volts, relay 4 dead electricity are not worked, contact K
8Discharge, resonant element and big electrical network are separated, thereby protected present embodiment, again because contact K
8Disconnect, the resonance cut-in voltage can be done lowlyer than national standard, thus high-pressure sodium lamp 7 can be low to moderate 150 volts at voltage can also operate as normal; When capacitor C occurring
1During puncture, electric current moment increase is with fuse RD
5Blow, avoided electric capacity puncture heating to cause the phenomenon of seriously catching fire.All electric elements of present embodiment are fixed on the wiring board 10; Hook 9, wiring board 10 are sealed in the shell 12 by epoxy resin 11.
[embodiment]
A circuit part of the present utility model is the resonant tank that main element is formed by electric capacity, high frequency transformer, controllable silicon, can produce high voltage pulse; Another part is the protective circuit that main element is formed by relay, rectifier bridge, is connected in parallel on the resonant tank.All electric elements are fixing in the circuit board, and by epoxy sealing in the enclosure.
After the utility model was finished and started sodium vapor lamp, the contact of relay discharges, and makes the utility model automatic trip from big electrical network, and was controlled Silicon and electric capacity can not be burned, and have protected preferably circuit; Because the contact of relay disconnects, the resonance cut-in voltage can be low again In national standard, thereby has the advantage that high-pressure mercury lamp also can be worked under low-voltage.
Claims (2)
1, a kind of high-pressure sodium lamp electronic trigger is characterized in that: having by electric capacity, high frequency transformer, controllable silicon is the resonant tank that main element is formed, and also has a protective circuit to be connected in parallel on the resonant tank in addition, contains relay, rectifier bridge in the protective circuit.
2, a kind of high-pressure sodium lamp electronic trigger according to claim 1 is characterized in that: also be provided with fuse and dropping resistor in the protective circuit.
