Tlhahlobo ea Sensor ea Quartz pele e kenngoa ho Weigh-In-Motion

Weigh-In-Motion (WIM) ke theknoloji e lekanyang boima ba likoloi ha li ntse li tsamaea, e felisang tlhoko ea hore likoloi li eme. E sebelisa li-sensor tse kentsoeng ka tlas'a tsela ho bona liphetoho tsa khatello ha likoloi li feta holim'a tsona, li fana ka data ea nako ea 'nete mabapi le boima ba 'mele, boima ba axle le lebelo. Sistimi ea WIM e sebelisoa haholo taolong ea sephethephethe, ts'ebetsong ea mojaro o mongata, le lisebelisoa ho ntlafatsa ts'ebetso le polokeho.

WIM e fana ka melemo e mengata, ho kenyeletsoa tšitiso e fokotsehileng ea sephethephethe, ho beha leihlo ka nako ea sebele, le ho ntlafatsa polokeho ea litsela ka ho lemoha likoloi tse tletseng ho feta tekano. Har'a mefuta e fapaneng ea li-sensor, li-sensor tsa quartz li loketse ka ho khetheha bakeng sa High-Speed ​​Weigh-In-Motion (HSWIM) ka lebaka la ho nepahala ha tsona, ho tšoarella, le bokhoni ba ho mamella maemo a thata a tikoloho. Li-sensor tsa quartz, tse kang CET8312-A, li fana ka ts'ebetso e tsitsitseng esita le ka lebelo le phahameng, e leng se etsang hore e be tse loketseng bakeng sa lits'ebetso tse hlokang ho lekanya boima ba 'mele bo nepahetseng le bo ka tšeptjoang maemong a sephethephethe a potlakileng.

Se latelang se hlahisa mekhoa e 'meli ea bohlokoa ea tlhahlobo e lokelang ho etsoa pele o kenya Sensor ea Quartz: Teko ea Insulation le Teko ea Waveform.

1. Mokhoa oa Teko ea Insulation

1) Kenya hlooho ea sensor Q9 ka har'a sokete ea megohmmeter

2) Beha megohmmeter ho 1000V boemo (e thibetsoe ho sebelisa boemo ba 2500V)

3) Fetolela 'me u tobetse sesebelisoa sa tlhahlobo ho ea ka nako, utloa molumo oa "beep", lebone le lefubelu le ka holimo le letona le bonesa ho qala tlhahlobo, nako ea teko ha ea lokela ho ba ka tlase ho metsotsoana e 5.

1) Liphetho tsa liteko joalo ka ha ho bonts'itsoe:

Pontšo ea sephetho sa OL unit (GΩ): Ts'ebetso e nepahetseng

Sephetho se bonts'ang 163 unit (MΩ): Ha e khonehe ho sebelisoa

TLHOKOMELISO EA BOHLOKOA!!! Ka mor'a ho hlahloba li-sensor ka megohmmeter, li-sensor li bokella matla a mangata a motlakase. Li-sensor li tlameha ho khutsufatsoa ho lokolla matla a bolokiloeng. Ho hokela lisebelisoa tsa ho fumana data kapa lisebelisoa tsa boima ntle le ho tsoa ka mor'a tlhahlobo ea insulation ho tla senya lisebelisoa tse nang le motlakase o phahameng, ho etsa hore li se ke tsa sebelisoa.

1.Waveform Test Mokhoa

1) Kenya hlooho ea sensor Q9 ka soketeng ea "CH1" ea oscilloscope, fetola nako ho 200ms le voltage ho 500mv, kapa fetola ho latela maemo a sebaka.

2) Sensor ea otla ka nako efe kapa efe ka hamore ea rabara, oscilloscope e lokela ho bonts'a tlhahiso ea waveform ea lets'oao

Ha ho tlhahiso ea lets'oao joalo ka ha ho bonts'itsoe kaholimo

Sephetho sa lets'oao joalo ka ha ho bonts'itsoe kaholimo

Positive waveform

Negative waveform

1.Sensor Quality Assessment

Maemo a Tekanyetso a Insulation:

• Yuniti ea OL GΩ: Ts'ebetso e nepahetseng
• E kholo ho feta 10 GΩ: Boemo bo botle
• Ka tlase ho 1 GΩ: E ka sebelisoa
• 300MΩ le ka tlase: E na le phoso (Sekhechana)
