Zvinhu Zvinomwe zveZinc Oxide Arrester

1. Kukwanisa kuyerera

Izvi zvinonyanya kuratidzwa mukukwanisa kwemubati kupinza mavoltage akasiyana-siyana emagetsi anodarika mheni, mavoltage anodarika simba, uye mavoltage anoshanda.

2. Zvinhu zvekudzivirira

Zinc oxide arrester chigadzirwa chemagetsi chinoshandiswa kuchengetedza michina yakasiyana-siyana yemagetsi musystem yemagetsi kubva mukukuvadzwa kwemagetsi akawanda, uye ine mashandiro akanaka ekudzivirira. Nekuti hunhu hwe volt-ampere husina kurongeka hweplate yevhavha yezinc oxide hwakanaka kwazvo, mazana mashoma ema microampere emagetsi anogona kupfuura pasi pemagetsi akajairika, izvo zviri nyore kugadzira chimiro chisina gap, kuitira kuti chive nekushanda kwakanaka kwekudzivirira, huremu hushoma uye saizi diki. Kana magetsi akawanda apinda, magetsi anoyerera neplate yevhavha anowedzera nekukurumidza, uye panguva imwe chete, amplitude yemagetsi akawanda inogumira, uye simba remagetsi akawanda rinoburitswa. Mushure meizvozvo, plate yevhavha yezinc oxide inodzokera kune yakasimba resistance state, kuitira kuti system yemagetsi igone kushanda zvakanaka.

3. Kushanda kwekuvhara chisimbiso

Chinhu chinobata chinoshandisa jekete remhando yepamusoro rine simba rekukwegura uye rinobata mweya zvakanaka. Matanho akadai sekudzora kudzvanywa kwerin'i yekusunga uye kuwedzera sealant anoshandiswa. Jekete receramic rinoshandiswa sechisimbiso kuti rive nechokwadi chekuti chinobata chisimbiso chakavimbika uye kuti chinobata chisimbiso chishande zvakanaka.

4. Hunhu hwemakanika

Zvinhu zvitatu zvinotevera zvinonyanya kutariswa: simba rekudengenyeka kwenyika rinofanira kumiriswa; kumanikidzwa kwemhepo kwakanyanya kunoshanda pachinhu chinobata; simba guru rekudhonza rinobvumirwa rewaya riri pamusoro pechinhu chinobata.

5. Kushanda kwekubvisa utachiona

Chinodzivirira zinc oxide chisina mipata chine simba guru rekudzivirira kusvibiswa.

Chiyero che creepage chakatsanangurwa nechiyero chenyika ndeichi: Chikamu II nzvimbo yekusvibiswa kwepakati: chiyero che creepage 20mm/kv; Chikamu III nzvimbo yekusvibiswa kweheavy: chiyero che creepage 25mm/kv; Chikamu IV nzvimbo yekusvibiswa kwakanyanya: chiyero che creepage 31mm/kv.

6. Kuvimbika kwakanyanya pakushanda

Kuvimbika kwekushanda kwenguva refu kunoenderana nemhando yechigadzirwa uye kana kusarudzwa kwechigadzirwa kwakakodzera. Hunhu hwechigadzirwa hunochikanganisa hunonyanya kuita zvinhu zvitatu zvinotevera: kunzwisisa kwechimiro chose chechibatiso; hunhu hwevolt-ampere uye hunhu hwekudzivirira kukwegura kweplate yevharuvhu yezinc oxide; mashandiro ekuvhara kwechibatiso.

7. Kushivirira mafrequency esimba

Nekuda kwezvikonzero zvakasiyana-siyana musystem yemagetsi, zvakaita sekuisa pasi kwechikamu chimwe chete, simba remagetsi rakareba uye kurambwa kwemutoro, simba remagetsi rinokwira kana kuti simba remagetsi rinokwira nekukurumidza rine amplitude yakakwira richagadzirwa. Chinomisa magetsi chine simba rekutsungirira simba rakati mukati menguva yakati. Kugona kuwedzera simba remagetsi.
