SCB yakatevedzana backup mudziviriri weSPD
Mafuse kana mabreaker breaker ari kushandiswa muhuwandu neSPD haaenderani nemapoinzi matatu anotevera.
1. Kana mheni inorova, inoputsika nekukanganisa uye inokuvadza nyore-SPD haigoni kutamba basa rekudzivirira mheni;
2. Kana iyo SPD ipfupi-inotenderera, iyo frequency yesimba haizovhiringidzwa. Apo SPD inokundikana kana kuti mutsara wemazuva ano hauna kukura apo pfupi-circuit inoitika, zvakaoma kuzadzisa kuputsa kwezvino zvinodiwa zve fuse uye muparadzi wedunhu. Kukonzera njodzi yemoto;
3. Kana mheni yemazuva ano ichirova, iyo yakasara voltage yakakwirira-kuvimbika kwemidziyo yekudzivirira mheni kunoderedzwa. Mukupindura kusapindirana kwezvigadzirwa zviri pamusoro, kambani yedu yakagadzira iyi nhevedzano yePSD backup vadziviriri mushure mekutsvaga kwenguva refu uye kusimudzira uye nenhamba yakawanda yemiedzo, iyo inogona kunyatso kurongeka neSPD kuona basa rekudzivirira mheni, uye kugadzirisa. kushandiswa kwemafuse kana mabreaker circuit seSPDs. Mudziviriri wekuchengetedza ane njodzi dzinogona kuitika
Mhedzisiro yakananga yekubatanidzwa kwechigadzirwa ichi uye SPD ndeiyi: pasi pekuita kwemheni yakakura, haizovhiringidziki kuti ivimbise kushanda kwakanaka kwebasa rekudzivirira mheni; apo SPD inokundikana, simba duku remagetsi ikozvino rinoyerera uye rinokurumidza kubviswa kuti rive nechokwadi chekuchengetedzwa kwegetsi remagetsi uye kushandiswa kwemagetsi.
Chigadzirwa chimiro uye maitiro ekuita.
1. kana kupfuudza overvoltage kunoitika mumutsara wemagetsi, SPD conduction ichapwanya nepakati pfupi, izvo zvinokonzeresa rwendo rwemagetsi netsaona. mushure meSCB backup mudziviriri yaiswa, dunhu rinogona kukurumidza kubviswa kana nguva pfupi yadarika overvoltage short circuit inoitika muSPD, kuitira kudzivirira tsaona dzinokonzerwa nekuparara kweSPD.
2. Kana mheni ichipfuura, SCB backup mudziviriri anogona zvinobudirira kudzivirira kugumburwa kwenhema, kuitira kuti muchengeti wekuvhiya agare ari munzvimbo inoshanda, achivimbisa kuchengetedzwa kwemagetsi kushandiswa.
Features
●Parametric control trip mechanism, kuongororwa kwesarudzo chaiyo yekupfuura ikozvino
● Ikozvino inokonzerwa inotyisa yakaderera, iyo inofananidzwa nefuse
● High-energy contacts, hupenyu hurefu hwebasa;
●Chimiro cheMicro-off, saizi diki, yakanakira kudzima magetsi kuti ienderane neSPD
● Kunyatsotsanangurwa, kusangana nezvinodiwa zveSPD 11, T2, uye T3;
● 35m njanji kuiswa, maererano nekuisa zvinodiwa pasi rose.
Kukura Kwechigadzirwa
Iyo yekuchengetedza inodzivirira inoita basa rakakosha, asi zvinoenderana nekuti zvigadzirwa zvako ndezvemhando yakanaka. Hunhu hwakanaka huchaita basa guru. Iwe unofanirwa kushandisa chekuchengetedza chekuchengetedza kudzivirira mheni. Mhedzisiro yakananga yemudziviriri wekuchengetedza inogadzirwa neLEIHAO Mheni Dziviriro Kambani uye SPD ndeyekuti SPD backup mudziviriri haingaputswe pasi pesimba rinorema mheni; Mushure mekunge SPD yaputsika, iyo diki simba frequency kuyerera ikozvino inogurwa nekukurumidza kuti ive nechokwadi chekuchengetedzwa kwegedhi remagetsi uye mashandisiro emagetsi.
Kana kuwedzeredza kwechinguvana kunoitika mumutsara wemagetsi, SPD inobatidzwa, izvo zvinotungamira kurwendo rwemagetsi netsaona. Mushure mekuisa SCB backup mudziviriri, dunhu rinogona kukurumidza kubviswa kana SPD ipfupi-inotenderedzwa nekupfuura kwepamusoro, nekudaro kudzivirira tsaona dzinokonzerwa nekuparara kweSPD. Kana mheni ichipfuura, iyo SCB backup mudziviriri inogona kunyatso dzivirira manyepo, kuitira kuti muchengeti wekuvhiya agare ari munzvimbo inoshanda, kuve nechokwadi chekuchengetedza kwekushandisa simba.
