GDDJ-HVC Substation Temperature Monitoring System

1. Kunja kwa dzenje lamtundu wamakono sensa yolondola kwambiri imagwiritsidwa ntchito nthawi zambiri m'malo mwa gawo lachitsanzo lachikhalidwe, lomwe limaphatikizansopo maulendo angapo osinthira.Pakuyesa, ma tabo afupikitsa angapo amafunikira kuti atsogolere zotchingira kumapeto kuti muyese chida.GDDJ - HVC imagwiritsa ntchito chikhalidwe chowongoka, ikhoza kukhazikitsidwa pafupi ndi zipangizo, kutsogolo kwa chishango sikunasweka ndipo kutalika kwake ndi kochepa kwambiri, zomwe zimapewa kutseguka kwa chitetezo.Sensa imatha kuzindikira molondola zizindikiro mkati mwa 100μA ~ 700mA.Impedance ya sensa ndiyotsika, imatha kupirira ma frequency amagetsi 10A ndi 10kA mphezi yapano, kukumana ndi mikhalidwe yogwiritsira ntchito pa intaneti.

2. Gawo lachitsanzo limagwiritsa ntchito chipolopolo cha aluminiyamu chosindikizira chotchinga madzi, ndikutengera cholumikizira chingwe chopanda madzi kuti chituluke chachiwiri, chomwe ndi choyenera kulumikiza;Sensa ikayikidwa, nthawi zambiri imakhala yopanda mphamvu.Poyesa, chingwe chachiwiri chokha cha gawo lachitsanzo chiyenera kulumikizidwa, ndipo "pulagi ndi kusewera" zingatheke popanda ntchito iliyonse pamapeto otetezera chingwe.

3. Purosesa yaikulu ya chipangizochi ndi American TI 32-bit floating-point high performance digital signal processor (DSP), yomwe imagwiritsa ntchito nthawi yeniyeni yogwiritsira ntchito ndipo imagwiritsa ntchito njira yowonjezera ya 16-bit, yothamanga kwambiri, yolumikizana ndi njira zambiri. sampling analogi digito converter (A/D) kuzindikira muyeso wa nthawi yeniyeni ndi kuwerengetsa mwatsatanetsatane kuchuluka kowunikidwa.Kutha kuyang'anira zida zingapo nthawi imodzi.

4. Njira ziwiri zodziwira pa intaneti zowonongeka kwa dielectric zingaperekedwe, zomwe zingathe kuyeza kusiyana kwa dielectric kutaya kusiyana ndi capacitance chiŵerengero cha zipangizo ziwiri capacitive mu gawo lomwelo, ndi PT yachiwiri voteji angagwiritsidwe ntchito ngati chizindikiro chizindikiro kuyeza capacitance ndi dielectric. kutaya kwa chipangizo.Pogwiritsa ntchito sensa yamakono komanso ukadaulo wapamwamba wosefera wa digito, vuto la kutayika kwa dielectric mwatsatanetsatane ndi kukhazikika limathetsedwa, kuphatikiza njira zodzitchinjiriza zamagetsi komanso ukadaulo wapamwamba kwambiri, kusefa kwa digito kumatha kuonetsetsa kuti zotsatira za mayeso otayika a dielectric sizikhudzidwa ndi kusokoneza kwa ma harmonic. ndi kusokoneza kugunda kwa mtima, ndi kulondola kotheratu mpaka ± 0.05%.

5. Ndi kudziwika kwa dielectric imfa kusiyana ndi capacitance chiŵerengero cha mu-gawo capacitive zida, izo sizingakhoze kokha kupewa kupotoza zotsatira dielectric imfa chifukwa cha ntchito PT voteji yachiwiri monga chizindikiro chizindikiro, komanso kuthandiza kuchepetsa chikoka cha kusokoneza gawo lamagetsi lamagetsi.

6. Chojambuliracho chimakhala ndi chophimba chachikulu cha LCD chowonetsera magetsi owonetseredwa, panopa, kutaya kwa dielectric, resistive current, capacitive current ndi deta zina.

7. Woyesa samangokhala ndi ntchito yowunikira moyo, komanso amatha kuyang'anira zida pa intaneti kwa nthawi yayitali, ndikulemba zokha zomwe zikuyang'aniridwa.

8. Dongosolo limatengera masensa akunja m'malo mwa "gawo lachitsanzo lachikhalidwe", lomwe lingasinthidwe mosavuta kuchokera ku "kuzindikira kwamoyo" kupita ku "kuyang'anira pa intaneti" pansi pazida zomwe zimagwiritsidwa ntchito bwino.Palibe chifukwa chochotsera masensa omwe adayikidwa, palibe chifukwa choletsa chipangizocho, ingowonjezerani unit yowunikira (IED).

9. Chojambulira chimagwiritsa ntchito mapangidwe onyamula, osavuta kugwiritsa ntchito, batire ya lithiamu mu makina imatha kukhala ndi maola 8 a nthawi yogwira ntchito mosalekeza, kukwaniritsa zofunikira zogwiritsira ntchito kumunda.
