FMUSER 532-1602 kHz Medium Wave Biconical Antenna Kusvika ku50kW Kupinza Simba

chii If Medium Wave Bmifananidzo Antenna uye How It Works

Iyo yepakati wave biconical antenna imhando ye wideband antenna inowanzo shandiswa kugamuchira redhiyo nhepfenyuro mune yepakati wave frequency renji. Inoumbwa nezvinhu zviviri zvakasimirirwa makoni akaiswa point-to-point, akafanana nehourglass kana peya yeaizikirimu makoni akabatanidzwa pazvigadziko zvawo. Iyi yakasarudzika dhizaini inobvumira kugamuchirwa kwehupamhi hwema frequency mukati mepakati wave bhendi, kazhinji kubva pa530 kHz kusvika 1710 kHz.

Tarisa yedu 10kW AM transmitter pane-saiti yekuvaka vhidhiyo akatevedzana muCabanatuan, Philippines:

Iyo yepakati wave biconical antenna inoshanda zvichibva pamusimboti wemagetsi emagetsi nemwaranzi uye kugamuchira. Kana iyo electromagnetic wave, yakatakura chiratidzo cheredhiyo, ichisvika kune antenna, inokwevera emagetsi anotenderera muzvinhu zveantenna. Iyi yazvino inoyerera pakati pemakoni maviri, ichigadzira munda wemagetsi wakatenderedza antenna.

Iyo biconical antenna's symmetrical chimiro inova nechokwadi chekuti magetsi emagetsi anopenya zvakaenzana kumativi ese, zvichiita kuti ive omnidirectional. Nekuda kweizvozvo, antenna inogona kutora masaini eredhiyo kubva kumakona ese, ichibvumira kugashira kwakavimbika kubva kwakasiyana nzira.

Izvo zvakaumbwa necone zvinhu zvebiconical antenna zvakanyatsogadzirwa kuti zviwane resonance pane inodiwa renji yepakati wave frequency. Iyi resonance inogonesa kufambiswa kwakanaka kweiyo yakagamuchirwa yemagetsi simba kune yakabatana inogamuchira kana yekutepfenyura system.

Nekuda kwehukuru hwayo hwebhendi uye kugamuchira omnidirectional, iyo yepakati wave biconical antenna inoshandiswa zvakanyanya munhepfenyuro yeredhiyo. Kukwanisa kwayo kutora zviratidzo kubva kumativi ose kunoita kuti zvive zvakanaka kune mamiriro ezvinhu apo kugamuchira kunoenderana uye kwakavimbika kunodiwa. Dhizaini uye kushanda kweyepakati wave biconical antenna inobatsira mukubudirira kwayo mukuona kufambiswa kwakanaka uye kugamuchirwa kwemasaisai eredhiyo masaini.

Zvinhu Zvikuru

1. Kwete Ground Grid: Iyo biconical chimiro inobvisa kudiwa kwegidhi yepasi, ichibvumira compact tsoka. Uku kuchinjika kunoita kuti antenna iiswe pamatenga edzimba kana zvikomo, ichipa sarudzo dzenzvimbo dzakasiyana.
2. Kunaka Kugadzikana: Iwo epamusoro neakadzika makoni anofambisa zvakananga kuyerera kweredhiyo, isingakanganiswe nezvinhu zvisina kugadzikana senge kuramba kwepasi, mamiriro evhu, zvinomera, mwaka, uye mamiriro ekunze. Yakanyanya kugadziridzwa yakakwira-voltage uye yakakwirira-tembiricha coefficient vacuum capacitors inovimbisa kushanda kwakadzikama, kunyangwe munzvimbo dzine tembiricha mutsauko unopfuura 60 madhigirii gore rese, pasina kuda kugadziriswa kwemaoko.
3. Yakaderera Electromagnetic Kusvibiswa: Iyo biconical antenna inotora yakasarudzika nzira yekuendesa, kuve nechokwadi kuzere resonance yeradiator pane inotakura frequency. Nekuda kweizvozvo, nzvimbo yemwaranzi inongovharirwa padyo neantenna, ichideredza kusvibiswa kwemagetsi uye kukanganisa nezvivakwa zvakatenderedza. Inogona kutorwa seyakanaka nharaunda kana "girinhi" antenna.
4. High Radiation Efficiency: Kusavapo kwepasi kuramba kurasikirwa, kusanganiswa neyakasiyana nzira yekufananidza inoshandiswa mudeployment network, inosimudzira kuita kwekumira wave ratio uye bandwidth. Nekufambisa simba rekuisa rakananga kune radiator zvichibva pane impedance ratio, iyo antenna inowana inofananidzwa nemwaranzi inoshanda kune iyo yechinyakare λ/4 wavelength antenna uku ichidzikisa zvakanyanya saizi yayo.
5. Inoshanda Dziviriro Yemheni: Iyo network inductance inofananidzwa kuti ive nechokwadi chekuti discharge inductance kubva kune radiator kusvika pasi haipfuure makumi mashanu µH, inongori 50/1th yekuburitsa inductance yechinyakare shongwe. Iyo inodzivirira mutoro kubva kusimba remheni ndeye <40 Ω (pfupi dunhu inductance <0.3 µH), zvichikonzera yakanakisa kudzivirira mheni.
6. Kuchengeteka, Kuvimbika, uye Kuchengeta-Mahara: Iyo yakagadzikana uye yakavimbika yakaderera koni inoratidzira ina-machubhu ekumisikidza base, nepo iyo yepamusoro cone inopenya tsvimbo uye tsvimbo-fin chimiro chinopa kushoma kupikisa mhepo. Iyo yepakati mhango inosanganisa yakanyatso kugadzirirwa yekudzivirira maitiro chimiro pamwe neakawanda akaumbwa zvinhu, kuve nechokwadi chekudzivirira kwakanyanya kumhepo uye kudengenyeka. Iyo shongwe muviri inopisa-kunyura yakabatiswa, ichipa yakanakisa anti-corrosion kuita uye haidi gadziriso.
