Maintenance uye kugadziriswa kwe pakati penguva magetsi system

Iyo yepakati frequency magetsi magetsi akakamurwa kuita zvikamu zvitatu: iyo yemvura system, iyo hydraulic system uye yemagetsi system. Chinonyanya kukosha ndechekuchengetedza hurongwa hwemagetsi.

Kudzidzira kwakaratidza kuti mazhinji ekukanganisa ari epakati frequency magetsi emagetsi system ane chekuita nenzira yemvura. Naizvozvo, nzira yemvura inoda kuti mhando yemvura, kudzvanywa kwemvura, tembiricha yemvura, uye kuyerera kunofanirwa kusangana nezvinodiwa zvemidziyo.

Magadzirirwo emagetsi emagetsi: Sitimu yemagetsi inofanirwa kugadziridzwa nguva nenguva. Nekuti chikamu chikuru chekubatanidza chedunhu chiri nyore kugadzira kupisa, izvo zvinogona kukonzera kupisa (kunyanya mutsara neiyo inouya mutsara voltage pamusoro pe660V kana iyo inogadzirisa chikamu inotora yakatevedzana boost modhi), kukundikana kwakawanda kusingatsananguriki kunoitika.

Mumamiriro ezvinhu akajairwa, kutadza kweyepakati frequency magetsi magetsi anogona kukamurwa kuita zvikamu zviviri: kusakwanisa zvachose kutanga uye kusakwanisa kushanda zvakajairika mushure mekutanga. Semutemo wakajairwa, kana chikanganiso chikaitika, iyo system yese inofanirwa kuongororwa zvizere kana paine kutadza kwemagetsi, izvo zvinosanganisira zvinotevera zvinhu:

(1) Simba rekushandisa: Shandisa multimeter kuti uone kana kune magetsi kuseri kweiyo main circuit switch (contactor) uye control fuse, izvo zvinobvisa mukana wekubviswa kwezvikamu izvi.

(2) Rectifier: Iyo inogadziridza inotora matatu-chikamu chakanyatsodzora bhiriji rectifier wedunhu, matanhatu thyristors, matanhatu pulse transformers uye matanhatu seti ekupikisa-capacitance anotora zvinhu.

Nzira iri nyore yekuyera thyristor ndeyekuyera cathode-anode yayo uye gedhi-cathode kupikisa ne multimeter yemagetsi barrier (200Ω block), uye thyristor haifaniri kubviswa panguva yekuyera. Mumamiriro ezvinhu akajairwa, anode-cathode kuramba kunofanirwa kuve kusingagumi, uye gedhi-cathode kuramba kunofanirwa kunge kuri pakati pe10-35Ω. Kunyanya kana kudiki kunoratidza kuti gedhi reiyi thyristor rinokundikana, uye harigone kukonzeresa kuitisa.

(3) Inverter: Inverter inosanganisira 4 (8) inokurumidza thyristors uye 4 (8) pulse transformers, iyo inogona kuongororwa maererano nepamusoro nzira.

(4) Transformer: Imwe neimwe mhepo yetransformer yega yega inofanirwa kubatana. Kazhinji, kushorwa kwedivi rekutanga kunosvika makumi emakumi, uye yechipiri kuramba ishoma ohms. Izvo zvinofanirwa kucherechedzwa kuti chikamu chekutanga chepakati frequency voltage transformer yakabatana mukuwirirana nemutoro, saka kukosha kwayo kwekudzivirira i zero.

(5) Capacitors: Capacitors akabatanidzwa mukufanana nemutoro anogona kuputswa. Macapacitor anowanzo kuiswa mumapoka pane capacitor rack. Iro boka rema capacitor rinofanirwa kuputirwa rinofanira kurongerwa kutanga panguva yekuongorora. Bvisa nzvimbo yekubatanidza pakati pebhawa yebhasi yeboka rimwe nerimwe rema capacitor uye huru yebhasi bar, uye kuyera kushorwa pakati pemabhazi maviri eboka rimwe nerimwe re capacitor. Kazhinji, inofanira kunge isingagumi. Mushure mekusimbisa boka rakashata, bvisa ndiro yemhangura ye capacitor yega yega inotungamira kubhawa yebhazi, uye tarisa imwe neimwe capacitor kuti uwane yakaputsika capacitor. Imwe neimwe capacitor inoumbwa neakawanda cores. Iyo goko idanda rimwe, uye imwe danda inotungamirwa kune yekupedzisira cap kuburikidza ne insulator. Kazhinji, musimboti mumwe chete unoputswa. Kana iyo inotungamira pane insulator ikasvetuka kubva, iyi capacitor inogona kuramba ichishandisa. Imwe mhosva ye capacitor ndeyekudonha kwemafuta, izvo zvisingawanzo kukanganisa kushandiswa, asi teerera kudzivirira moto.

Iyo angle simbi iyo iyo capacitor yakaiswa inovharirwa kubva kune capacitor frame. Kana kuparara kwekudzivirira kuchidzika dunhu guru, kuyera kupikisa pakati pe capacitor shell lead uye capacitor frame kuti uone mamiriro ekudzivirira echikamu ichi.

1. Mvura-yakatonhorera tambo: Basa remvura-yakatonhorera tambo ndeyekubatanidza yepakati frequency magetsi magetsi uye induction coil. The torsion force, tilts uye twists nechoto chemoto, saka zviri nyore kutyora pane inochinjika yekubatanidza (kazhinji iyo yekubatanidza yemuviri wechoto) mushure menguva refu. Mushure mokunge tambo yakanyoroveswa yemvura yakabviswa, magetsi emagetsi epakati haakwanisi kutanga kushanda. Paunenge uchisimbisa kuti tambo yakatyoka, tanga wabvisa tambo yakanyoroveswa nemvura kubva kune capacitor inobuda mhangura bar, uye kuyera kupikisa kwetambo ine multimeter (200Ω block). Iko kukosha kwekupokana ndeye zero kana yakajairika, uye haina magumo kana yabviswa. Paunenge uchiyera ne-multimeter, mutumbi wevira unofanira kushandurirwa kunzvimbo yekurasira kuitira kuti tambo yakanyungudutswa yemvura iwire pasi, kuitira kuti chikamu chakaputsika chigone kuparadzaniswa zvachose, kuitira kuti chikwanise kutongwa zvakarurama kana chakaputsika kana kwete.
