Satellite TV inogona kusvika kumativi ari kure kwazvo epasi, uko pasina vanopa vakajairwa uye shongwe dzekutepfenyura. Iyo inowanikwa compact system inogona kuiswa chero kupi. Iyo satellite dish inopa iyo ine ruvara uye yakajeka mufananidzo. Tambo yakajairika inoshandiswa pasatellite TV ndeye satellite coaxial tambo.
Kugamuchirwa kwakavimbika kunoenderana nekugadzika uye hunyanzvi hwekushandisa. Netambo, zvinokwanisika zvose kuvandudza nekuchengetedza zviratidzo zvehutano uye kuderedza mikana yezvisarudzo zvisiri izvo.
Saka ungasarudza sei satellite tambo uye kuti ungaitarisa sei usati waitenga? Rega mupepeti wekambani yeZMS cable akutore kuburikidza netambo dzesatellite.
Chii chinonzi Satellite Coaxial Cable?
Satellite coaxial tambo ine maviri-conductor anosanganisira yemukati conductor uye network inodzivirira..
Sezvo mbezo dzemaconductor maviri aya dzichipindirana, inonzi coaxial tambo kana coaxial line.
Satellite coaxial tambo ine zvikamu zvina: mukati conductor mhangura musimboti, insulator, simbi inodzivirira network uye aluminium composite firimu, uye sheath.
Inner conductor copper core is solid core conductor.
Iyo insulator inogadzirwa ne polyethylene, iyo ine yakaderera dielectric kurasikirwa uye yakanaka engineering kuita.
Metal shielding network uye aluminium composite firimu, pamwe chete kupedzisa basa rekudzivirira uye kunze conductivity. Iyo aluminium composite firimu inonyanya kupedzisa basa rekudzivirira, nepo simbi inodzivirira network inopedzisa iyo mbiri basa rekudzivirira uye kunze conductivity.
Iyo sheath ndeyekudzikisa kuchembera kwetambo uye kudzivirira kukuvara.
Satellite Coaxial Cable Hunhu
Iyo yakakosha kutapurirana maitiro e satellite coaxial tambo ndiko kuti yakakwirira frequency, zvikuru kuderedza.
Kana iyo tambo yepakati yakanyanya kutetepa uye network yekudzivirira yakanyanya kutetepa, kudonha uye kuderedzwa kwechiratidzo kuwedzera, nokudaro zvichikonzera kuderedzwa kwehutano hwechiratidzo.
Semugadziri wechiratidzo chemagetsi, chigadzirwa chine hunyanzvi uye maitiro emuviri.
Mitemo yeinjiniya yemagetsi inotaura kuti AC inonyanya kugoverwa pamusoro peiyo conductor. Iyo diki inogoneka iri pedyo nepakati.
Saka, iyo yakakora iyo cable conductor, diki kudzikisira kwerudzi rwepesvedzero. Iyo yakajairika dhayamita yeTV antenna centerline: 0.5-1 mm.
Anti-wave
Chiyero chekuyeresa chesimba ndiyo ohm. ZveTV netambo dzesatellite, 75 ohms inonyanya kushandiswa.
Iyi ndiyo impedance yekupinza yekubatanidza iyo tambo yakabatana nayo. Kusawirirana kwenhamba kuchaita kuti kuderedzwa kwezvino zvingaita.
Mukushaikwa kwekuenzana kwewaya kuramba, kubatanidza kunogona kuitwa nemaitiro akasiyana pamusoro pezvinhambwe zvipfupi. Semuyenzaniso, mudzimba dzavanhu.
Satellite Coaxial Cable sarudzo
Setiraiti tambo mudziyo wekunze. Chikamu chenzira yetambo inoda kuiswa munzvimbo dzakashama. Saka kusarudza sei coaxial tambo yakakosha.
1 Outer Sheath Material
Inokurudzirwa kusarudza tambo yakagadzirwa ne polyethylene base material. Izvi zvinodaro nekuti haibatike nyore nezvinhu zvakaomarara, zvakadai semamiriro okunze akaipa kana kupisa kwakanyanya. Semuyenzaniso, mamiriro okunze akaipa kana kupisa kwakanyanya, etc. PVC zvinhu ichachengetedza tambo kubva pakatsemuka kunokonzerwa nekutonhora kunze nekuti kutonhora kuchaparadza tambo yekuvharisa.
Zvakananga, hunyoro hunotonhora hunopinda mukati metambo uye hunokonzera pfupi pfupi. Midziyo yacho inozotadza kushanda. Sarudza coaxial tambo dzine yakakosha impregnation yemamiriro akaoma kana uchitenga.
2 Insulation Structure
Kutepfenyura kwesatellite kune maitiro ekuparadzira, saka inoda mutsara wakananga wekuona pakati peiyo radiation sosi netambo. Kukwenya matavi emiti munzira, pedyo newaya zvivakwa, uye kunaya kwakanyanya uye kunaya kwechando kunogona kukonzera dambudziko rakawanda kumatambo ekunze. Saka zvakakosha kuchengetedza chiratidzo chiripo chekugamuchira uye kuunza kune anogamuchira.
Mukuwedzera kune zviratidzo zveTV, converter control mirairo inofanira kuendeswa kuburikidza netambo. Saka iwe unofanirwa kusarudza chigadzirwa chine kaviri-layer yemukati network, seyakarukwa coaxial, ine chidimbu chealuminium foil.
3 Cable Bending Resistance
Satellite coaxial cables haawanzoiswa mumutsara wakatwasuka kana akaiswa. Saka, tambo inoda kusarudzwa uchifunga kana tambo ichatsemuka nyore mushure mekukotama.
4 Kuenzanisa kweCables
Mumamiriro ezvinhu akafanana, tambo dzakakora dzinokunda tambo dzakatetepa. Physical foam cable yakakwirira kune yakasimba tambo. Iyo yakakwirira yakarukwa tambo iri nani pane yakaderera yakarukwa tambo. Copper-core cable iri nani pane copper-clad simbi tambo. Copper yakarukwa network tambo yepamusoro kune aluminium-magnesium alloy tambo.
Parizvino, iyo inowanzoshandiswa satellite coaxial tambo imhando 75-5. Kune iyo yekugamuchira sisitimu ine mitsara refu yekutumira, iyo inopindira-resistant coaxial cable inofanira kushandiswa.
Iyo yakapetwa kaviri-insulated uye kaviri-shielded coaxial tambo. Nheyo yayo, kusimbisa, uye nhovo ichiri yakajairwa 75-ohm tambo.
Asi mutsauko ndewekuti chikamu chechipiri chekudzivirira uye chechipiri chekudzivirira chinowedzerwa kune yekutanga shielding layer.. Uye sheath inowedzerwa kunze, saka ine yakanakisa anti-kupindira kuita.
Satellite Coaxial Cable Installation
Nyanzvi dzine ruzivo dzinoti magetsi isayenzi inogona kubatwa. Kana iwe usina kungwarira paunenge uchiisa tambo, hazvizoshandi kana kuva nengozi. Saka nzira yekuisa tambo yakakosha zvikuru.
1 Kana mugamuchiri ari 10-15 mamita kubva kune satellite cable, iwe unogona kutenga yakagadzirira-yakagadzirwa sampuli yetambo ine zvibatanidza. Connector F contacts anoiswa pamagumo etambo.
Semuyenzaniso, iyo RG-6 tambo inoreva kuti inokodzera tambo dzeRF dzine yekunze insulation dhayamita ye 6 mm.
2 Usati watenga tambo, tsvaga kureba kwetambo inodiwa, uye chikamu chekuisa chakaoma.
3 Dzivisa kukotama mumakona akapinza paunenge uchiisa kudzivirira kutsemuka.
4 Pakuisa, pakubvarura kubva pamadziro kuenda kumugwagwa, inoita yakadzika loop yetambo. Nzira iyi, mvura inonaya inodonha ichidzika kana kunaya pane kudonhedza goko mugomba.
5 Paunenge uchiisa kuburikidza nehuni hwindo furemu, chera gwara rine dhayamita rakakura kupfuura ukobvu hwetambo.
6 Panyaya yemapuranga epurasitiki, inokurudzirwa kuti isaburitse. Iwe unogona kushandisa gap pakati pehwindo nemadziro, yakazara ne polyurethane foam.
7 Kana yakaiswa mumba, tambo inogona kuvanzwa mubhokisi repurasitiki kana skirting board ine cable channel.
8 Usaisa tambo pamwe chete nedzimwe tambo. Kana iri pedyo nemichina ine simba nemidziyo, inogona kuve sosi yekuvhiringidza nesatellite coaxial cables.
9 Nama pokubuda napo kunzvimbo yakashama. Mumamiriro emhepo, mitsetse iri pamusoro pekunze yakatwasuka haifanire kunyungudika nekuzungunuka zvakasununguka.
Satellite coaxial tambo yekuongorora
Tarisa kuvimbika kwetambo mushure mekuiswa kwapera. Tarisa kuderedzwa kwemhando yemufananidzo, screen rippling color bars kana mufananidzo kupatsanurwa kuita diki mativi, inzwi rakakanganiswa, etc.
1 Bvisa tambo kubva pahinge point iri padyo nekamuri.
2 Bvisa chibatanidza kuburikidza nenhoo uye pakati conductor.
3 Gadzirira midziyo inoshandiswa kuyera kuramba.
4 Tarisa wiring yakananga kune antenna. Batanidza bvunzo inotungamira kune yepakati core uye simbi sheath.
Chenjera kuti usabata conductor. Kana iyo core iri mumamiriro akanaka, mudziyo ucharatidza kukosha kwete 1, asi kwete 0.
Kana wadzima, kuverenga kunozoita zero kana kuratidza 0 uye chiratidzo chinonzwika chichaonekwa. Zvakare, paunenge uchitarisa tambo yekamuri, tambo inofanira kubatanidzwa kune anogamuchira.
Izvo zviri pamusoro ndiko kusuma uye kusarudzwa kwesatellite coaxial tambo. ZMS cable mugadziri yakazvipira kupa tambo dzakawanda dzemhando yepamusoro, neyakaomesesa yemanyorero ongororo yezvigadzirwa uye sevhisi ine hanya kune vatengi. Hunyanzvi hwepamusoro mukugadzira tambo uye zvigadzirwa zvinovimbika.
