Muchirimo, mabhanan'ana anonyanya kuitika, kurova kwemheni kuyerera kwemagetsi kunowanzo kutumira mamirioni emavolts kubva mugore kuenda pasi kana rimwe gore. Painofamba, mheni inogadzira nzvimbo yemagetsi mumhepo iyo inogadzira zviuru zvemavolts (anozivikanwa sema surges) patambo dzemagetsi uye inonyandurwa ikozvino mazana emamaira kure. Kurwiswa kusina kunanga uku kunowanzoitika panze patambo dzemagetsi dziri pachena, semarambi emumugwagwa. Midziyo yakaita semarambi emotokari uye zviteshi zvepasi zviri kutumira masaisai. Iyo surge yekudzivirira module yakanangana nekupindira kwekuvhiya kubva kutambo yemagetsi kumucheto wepamberi wedunhu. Inotumira kana kutora simba rekuwedzera kuderedza kutyisidzira kwekuvhiyiwa kune mamwe maseketi anoshanda, senge AC/DC magetsi emagetsi mumidziyo yemwenje ye LED.
Kune magetsi emumugwagwa e LED, mheni inogadzira kukwidziridzwa kwetambo yemagetsi. Kuwedzera kwesimba uku kunogadzira shockwave pawaya, ndiko kuti, shockwave. Kuvhiya kunofambiswa neiyi induction. Nyika iri kuwanda. Iyo wave ichaburitsa tipi pane sine wave pamwe neiyo 220 v transmission line. Kana iyo muromo ichipinda mumwenje wemugwagwa, ichakuvadza iyo LED mwenje mwenje wedunhu.
Nokudaro, kudzivirirwa kwemheni yemarambi emigwagwa ye LED kuchabatsira hupenyu hwavo hwebasa, izvo zvino zvinodiwa.
Saka izvi zvinoda kuti tiite basa rakanaka rekudzivirira kwemheni dze LED traffic, zvikasadaro zvinokanganisa kushandiswa kwayo kwakajairika, zvichikonzera mhirizhonga yemumigwagwa. Saka ungaita sei kudzivirira mheni kwemarambi emagetsi e LED?
1.Isa ikozvino inodzikamisa mheni tsvimbo pambiru ye LED traffic chiratidzo mwenje
Kuvimbika kwemagetsi nemagetsi kubatanidzwa kunofanirwa kuitwa pakati pepamusoro petsigiro uye hwaro hweiyo inodzikamisa mheni tsvimbo. Zvadaro, rubatsiro runogona kuiswa pasi kana kubatanidzwa kune network yepasi yerutsigiro pachayo nesimbi yakatsetseka. Kupikisa kwepasi kunofanira kunge kuri pasi pe4 ohms.
2. Overvoltage mudziviriri inoshandiswa sesimba rekuchengetedza magetsi pamberi peiyo LED traffic chiratidzo mwenje uye chiratidzo chekudzora mechini uye magetsi sosi.
Isu tinofanirwa kutarisisa kusapinda kwemvura, hunyoro-uchapupu, husina guruva uye waya yemhangura ye overvoltage mudziviriri yakabatana negonhi rekuisa pasi kiyi zvakateerana, uye kupikisa kwepasi kwakaderera pane yakataurwa kukosha kwekupikisa.
3. Kudzivirirwa kwepasi
Kune yakajairwa mharadzano, mbiru yayo uye yekumberi-yekupedzisira midziyo yekugovera yakapararira, saka isu tinoda kuwana imwe nzvimbo yekudzika ichave yakaoma. Saka kuitira kuti ive nechokwadi chekuti marambi emagetsi e LED anoshanda pasi uye kuchengetedzwa kwemunhu, chete mumbiru yega yega pasi pekushandiswa kweiyo yakamira yakadzika yemuviri yakasungirirwa mune network chimiro, ndiko kuti, akawanda-point grounding mode yeinouya wave zvishoma nezvishoma kuburitswa uye dzimwe mheni. kuchengetedzwa zvinodiwa.
