Maimaiya Metal Oxide Surge Arrester shine?

Bayani：Arrester da take amfani da zinc oxide semiconductor a matsayin yanayin shirye-shiryen yana nufin metal oxide surge arrester ko ZnO Diverter. Wani abu na iya inganta waɗannan kimiyya yana da muhimmanci wajen inganta waɗannan kimiyya daga fadada AC da DC over - voltages. Ana amfani da shi wajen inganta waɗannan kimiyya a duk fadada volts a cikin gwamnati.

Bini da Ingantaccen Metal Oxide Surge Arrester：Zinc oxide wani abu na N - type semiconducting material. Ana juye shi zuwa hanyar fine - grained state. Ana zama masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da suka sauran ten masu zaɓuwa da su......

Sau da haka, an zama shi zuwa abu na fine powder. Ana zama shi zuwa disc - shaped blocks. Ana sinter da waɗannan blocks don samun abu na dense poly - crystalline ceramic. An kofin metal oxide resistor disc da conducting compound don inganta disc daga fadada yawan gida.

Conducting coating ya ba da muhimmanci wajen bayyana electrical contacts kuma ya ba da uniform current distribution across the disc. Sau da haka, ana baka disc a cikin porcelain housing da take kula da nitrogen gas ko SF6 gas. Ana amfani da silicon rubber don fix disc a matsayin kuma ya taimakawa wajen tsara heat daga disc zuwa porcelain housing. Disc ya danganta da pressure tun daga appropriate springs.

ZnO element a cikin diverter ya gaji irin series spark gaps. Voltage drop a cikin ZnO diverter ya faru a grain boundaries. A boundaries of each ZnO grain, akwai potential barrier wanda ke kontrola flow of current from one grain to the next.

A lokacin da voltage conditions masu normal, wannan potential barrier ya sauraro current from flowing through. Amma a lokacin da over - voltage situations, barrier ya kawo rage, wanda ya haɗa zuwa sharp transition of the current from an insulating state to a conducting state. Saboda haka, current ya faru, and the surge ya zama safe ta zama ground.

Sau da surge ya zama, voltage across the diverters ya rage, and the current reduces to a negligible value in the resistor units. Notably, there is no power follow - current.

Abubuwan da Metal Oxide Surge Arrester Ke Da Su

Metal oxide surge arrester ke da su abubuwan da su:

• Yana cire risks of spark - over and the associated shock to the system when gaps break down.

• Yana cire requirement for a voltage grading system.

• A lokacin da operating conditions masu normal, leakage current a cikin ZnO arrester ita ce significantly lower compared to other types of diverters.

• Ba a kuwa power follow - current a cikin ZnO diverter ba.

• Yana da high energy - absorbing capacity.

• ZnO diverters suna nuna high stability both during and after prolonged discharge.

• A cikin ZnO diverter, mumkin a kontrola not only switching surges but also dynamic over - voltages. Wannan yana ba da cost - effective insulation coordination.

Note: Sintering ita ce process of creating a solid mass of material. Wannan an samun shi either by heating the material or by applying pressure to it without melting the material.
