Description

Electronic ballast of high voltage sodium lamp with the automatic measuring ability of fault

Technical field

The utility model relates to a kind of electric lighting parts, particularly a kind of electronic ballast of high voltage sodium lamp with the automatic measuring ability of fault.

Background technology

High-pressure sodium lamp becomes one of green light source in the electric lighting field owing to characteristics such as having light efficiency height, good, the long working life of colour developing mist transmitting, is widely used at present in the roadway lighting system of railway, harbour, highway.As everyone knows, high-pressure sodium lamp belongs to gas discharge tube, and must be equipped with ballast during use could starter work.At present and the ballast that matches of high-pressure sodium lamp mainly contain two kinds of inductance type and electronic types.Inductance type ballast owing to when starting impulse current big, power factor is low, power consumption is big, lamp tube service life is short is superseded day by day; Electronic ballast is because to have a starting current little and be convenient to brightness adjustment control, reduce the power consumption at night, realize advantages of saving energy and reducing emission and popular day by day.High-pressure sodium lamp is mainly used in road night illumination aspects along the line such as railway, harbour, highway, can take place in the time of in the use to cause the situation of turning off the light because of fluorescent tube damage, line fault, ballast fails and fuse failure and other reasons, and in a single day the situation of turning off the light when taking place, owing to there is not automatic detection device at present, can only rely on artificial periodical inspection to find, timely discovery and maintenance that this certainly will influence the situation of turning off the light influence road normal illumination along the line.In addition, do not work, can't judge intuitively to cause the definite reason of turning off the light, can't be confirmed to be that to belong to line fault still be the equipment fault though the tour personnel can find a certain lamp position intuitively.Not necessarily can reach the purpose that recovery is lit a lamp if under agnogenic situation, replace the high-pressure sodium fluorescent tube blindly, also might cause the follow-up continuous damage of high-pressure sodium fluorescent tube and other accessory, this not only increases the workload of street lamp regular maintenance, also cause improving maintenance cost, and influence the work quality of electrical lighting system, thereby from economy and point of view of practicability consideration, it is desirable that the electron rectifier of the automatic measuring ability of existing fault-free is still owed.

Summary of the invention

The purpose of this utility model is that a kind of have automatic fault detection and energy will be provided IntelligentlyThe definite position that judgement is broken down and the novel electronic ballast of high voltage sodium lamp of fault type.

Of the present utility model have the electronic ballast of high voltage sodium lamp main body of the automatic measuring ability of fault by housing, electric external terminal and electric member are formed, electric external terminal is arranged on the housing, include alternating current 220V input and the high frequency voltage output of lighting a lamp, electric member is arranged on enclosure interior, by the lightning protection and the electromagnetic compatibility EMC circuit that include band alternating current 220V input, working power circuit, the AC/DC change-over circuit, the DC/AC change-over circuit, drive circuit, light a lamp fluorescent tube circuits for triggering of output and the ballast circuit of central processor CPU and the light adjusting circuit that is arranged on the central processor CPU output control terminal of last band high frequency voltage constitute, be characterised in that also to comprise in the electric member and be provided with failure detector circuit that the photoelectric coupled device that is made of light-emitting diode and phototriode and detection module constitute and the communication module circuit of going up band communication interface end, wherein: described photoelectric coupled device is provided with four groups, be separately positioned on the signal input part of detection module and the AC/DC change-over circuit in the ballast circuit, the DC/AC change-over circuit, drive circuit, between each test point of fluorescent tube circuits for triggering, the signal output part of described detection module and the signal input end of central processor CPU are electrically connected, and the described communication module circuit of going up band communication interface end is arranged on the control signal output ends of central processor CPU.

During work, by the AC/DC change-over circuit that is connected across in the ballast circuit, the DC/AC change-over circuit, drive circuit, light-emitting diode real-time tracking in the photoelectric coupled device on each test point of fluorescent tube circuits for triggering detects, when the AC/DC change-over circuit, the DC/AC change-over circuit, drive circuit, in the fluorescent tube circuits for triggering during arbitrary circuit generation non-normal working situation, all can make corresponding light-emitting diode change operating state, thereby the operating state of corresponding change phototriode, so on detection module, receive signal, central processor CPU receives the relevant detection signal, and make intelligent decision according to received signal, send out the testing result cue that can definitely reflect break down position and type to the communication module circuit, send bulletin information by the communication interface end to streetlight monitoring department then.

The electronic ballast of high voltage sodium lamp that the utlity model has the automatic measuring ability of fault based on above-mentioned design, be provided with and detect the ballast circuit working condition by real-time tracking owing on the basis of existing circuit of electronic ballast, increase, the testing circuit that is made of photoelectric coupled device and detection module reaches the communication module circuit of going up band communication interface end, the light-emitting diode cross-over connection is arranged on the AC/DC change-over circuit of ballast circuit in the photoelectric coupled device, the DC/AC change-over circuit, drive circuit, on each test point of fluorescent tube circuits for triggering, just in case when in the circuit operation irregularity situation taking place, the light-emitting diode that order about on the respective detection point in the capital changes operating state, order about corresponding phototriode and change operating state, send the working signal of expression related circuit fault, after the central processor CPU intelligent decision, communication interface end by the communication module circuit sends clear and definite bulletin information to streetlight monitoring department, be convenient to manage or the maintenance personal in time understands the turn off the light reason of fault of the instant illumination work situation of roadway lighting system and current turn off the light situation and initiation, help in time, and keep in repair with a definite target in view, recover.So, the electronic ballast of high voltage sodium lamp that the utlity model has the automatic measuring ability of fault is compared with any a electronic ballast of high voltage sodium lamp of the prior art, owing to increased fault detect automatically and the break down automatic prompt facility of position and classification, it is more timely obviously to have fault discovery, it is more convenient to fix a breakdown, can greatly reduce the workload of maintaining and reduce unnecessary spillage of material, more help improving the work quality of roadway lighting system, whole illuminator is reached a new high, guarantee the safe operation of road, thereby have very strong practicality and economy, be the desirable renewal product of existing electronic ballast of high voltage sodium lamp.
