I. Pfungwa Dzekutanga dzeMabhokisi Ekuparadzira
Bhokisi rekugovera ndiro chinhu chikuru muhurongwa hwemagetsi chinoshandiswa pakugovera simba remagetsi pakati, kudzora maseketi uye kudzivirira michina yemagetsi. Rinogovera simba remagetsi kubva kumagetsi (akadai sematransformer) kuenda kumidziyo yemagetsi yakasiyana-siyana uye rinobatanidza mabasa ekudzivirira akadai sekuwanda kwemagetsi, kupfupika kwemagetsi uye kubuda kwemvura.

Mashandisirwo makuru:

Kugoverwa nekudzorwa kwesimba remagetsi (senge magetsi emwenje nemidziyo yemagetsi).

Dziviriro yedunhu (kurema zvakanyanya, kupfupika kwedunhu, kubuda kwemvura).

Tarisa mamiriro edunhu (voltage uye current display).

Ii. Kupatsanurwa kwemabhokisi ekugovera
Zvichienderana nemamiriro ezvinhu ekushandisa:

Bhokisi rekugovera zvinhu mumba: Diki, rine dziviriro yakaderera, rinobatanidza dziviriro yekubuda kwemvura, maswichi emhepo, nezvimwewo.

Bhokisi rekugovera zvinhu mumaindasitiri: Kukwanisa kukuru, dziviriro yepamusoro (IP54 kana kupfuura), inotsigira kudzora dunhu rakaomarara.

Bhokisi rekugovera rekunze: Risingapindi mvura uye rinodzivirira guruva (IP65 kana kupfuura), rakakodzera nzvimbo dziri pachena.

Nenzira yekuisa:

Rudzi rwekuisa pachena: Yakanamirwa zvakananga pamadziro, iri nyore kuisa.

Rudzi rwakavanzika: Rwakaiswa pamadziro, runonakidza asi magadzirirwo acho akaomarara.

Nechimiro chechimiro:

Rudzi rwakagadziriswa: Zvikamu zvinoiswa nenzira yakatarwa, nemutengo wakaderera.

Rudzi rwedhirowa (bhokisi rekugovera zvinhu zvemodular): Dhizaini yemodular, yakakodzera kugadziriswa nekuwedzera.

Iii. Maumbirwo emabhokisi ekugovera
Muviri webhokisi:

Zvinhu: Simbi (ndiro yesimbi inotonhorera, simbi isingatsvi) kana isiri simbi (purasitiki yeinjiniya).

Dziviriro: Makodhi eIP (akadai seIP30, IP65) anoratidza kugona kudzivirira guruva nemvura.

Zvikamu zvemagetsi zvemukati:

Zvidziviriro zvemagetsi: Zvidziviriro zvemagetsi zvakanyanya/zvipfupi (zvakadai semaswichi emhepo, zvidziviriro zvemagetsi zvemagetsi zvakagadzirwa).

Chinodzima magetsi: Cheka magetsi nemaoko.

Mudziyo wekudzivirira kubuda kwemvura (RCD): Unoona kubuda kwemvura uye kufamba kwemvura.

Chiyero chemagetsi: Kuyera simba remagetsi.

Contactor: Inodzora kuvhurwa nekubviswa kwesekiti iri kure.

Chidziviriro cheSurge (SPD): Chinodzivirira kubva pakurohwa nemheni kana overvoltage.

Zvimwe zvikamu zvekubatsira:

Mabhazi (mabhazi emhangura kana aruminiyamu), mabhuroko emagetsi, marambi ekuratidza, mafeni ekutonhodza, nezvimwewo.

Iv. Magadzirirwo ehunyanzvi ebhokisi rekugovera
Rated current: senge 63A, 100A, 250A, iyo inofanira kusarudzwa zvichienderana nesimba rose remutoro.

Voltage yakayerwa: Kazhinji 220V (chikamu chimwe chete) kana 380V (chikamu chetatu).

Dhigirii rekudzivirira (IP): senge IP30 (inodzivirira guruva), IP65 (inodzivirira mvura).

Kutsungirira kwemhepo pfupi: Nguva yekutsungirira mhepo pfupi (yakadai se10kA/1s).

Kukwanisa kupwanya: Kukwanisa kukuru kwemagetsi kunogona kuchekwa ne circuit breaker zvakachengeteka.

V. Gwaro Rekusarudza Mabhokisi Ekuparadzira
Zvichienderana nerudzi rwemutoro:

Dunhu remwenje: Sarudza chinodzora mwenje che10-16A (MCB).

Midziyo yemota: Zvinodzorwa nethermal relay kana macircuit breaker anoenderana nemota anofanira kuenzaniswa.

Nzvimbo dzinonyanya kubatwa nehutachiona (dzakadai sedzimba dzekugezera): Mudziyo wekudzivirira kubuda kwemvura (30mA) unofanira kuiswa.

Kuverenga kugona

Mari yese yemagetsi i ≤ iyo ratio yemagetsi yebhokisi rekugovera × 0.8 (muganho wekuchengetedza).

Semuenzaniso, simba rese remutoro i20kW (matatu-phase), uye magetsi ari padanho re30A. Zvinokurudzirwa kusarudza bhokisi rekugovera re50A.

Kuchinjika kwezvakatipoteredza

Nzvimbo ine hunyoro: Sarudza bhokisi resimbi isina ngura + giredhi rekudzivirira rakakwirira (IP65).

Nzvimbo inodziya zvakanyanya: Maburi kana mafeni anodiwa.

Zvinodiwa zvakawedzerwa:

Chengetedza 20% yenzvimbo isina chinhu kuti zvive nyore kuwedzera maseketi matsva gare gare.

Vi. Kudzivirira Kuisa Nekugadzirisa
Zvinodiwa pakuiswa:

Nzvimbo yacho yakaoma uye ine mhepo inofefetera zvakanaka, kure nezvinhu zvinobvira moto.

Bhokisi racho rakavakirwa zvakasimba kudzivirira njodzi yekubuda kwemagetsi.

Ruvara rwewaya (waya iri mhenyu dzvuku/yero/girini, waya isina kupindirana yebhuruu, waya yepasi yero yegirini).

Pfungwa huru dzekugadzirisa:

Gara uchitarisa kana waya dzakasununguka kana kuti dzakaoxidized.

Geza guruva (kudzivirira ma "short circuits").

Edza mudziyo wekudzivirira (sekudzvanya bhatani rekudzivirira kubuda kwemvura kamwe chete pamwedzi).

Vii. Matambudziko Akajairika uye Mhinduro
Kugumburwa kakawanda

Chikonzero: Kutakura zvinhu zvakawandisa, kupfupika kwemhepo kana kubuda kwemvura.

Kugadzirisa Matambudziko: Bvisa mutsetse wekutakura nemutsetse wobva waona dunhu rakakanganisika.

Kugumburwa kwemudziyo wekudzivirira kubuda kwemvura

Zvinogoneka: Kudzivirira kukuvara kwedunhu, kubuda kwemagetsi kubva mumidziyo.

Kurapa: Shandisa megohmmeter kuti uedze kudzivirira kudziya kwemhepo.

Bhokisi riri kupisa zvakanyanya.

Chikonzero: Kutakura zvakanyanya kana kusabata zvakanaka.

Mhinduro: Deredza mutoro kana kusimbisa mabhuroko ekupedzisira.

Viii. Mitemo Yekuchengetedza
Inofanira kutevedzera mitemo yenyika (yakadai seGB 7251.1-2013 “Low-voltage Switchgear Assemblies”).

Pakuisa nekugadzirisa, magetsi anofanira kudimburwa uye mashandiro acho anofanira kuitwa nenyanzvi dzemagetsi.

Hazvibvumidzwe kugadzirisa macircuit emukati kana uchida kana kubvisa zvishandiso zvekudzivirira.
