Mabasa uye Mashandisirwo eRCD Type B 30mA

KunzwisisaRudzi B RCDs 30mA: Gwaro Rakazara

Munyaya dzekuchengetedza magetsi, zvishandiso zvemagetsi zvinosara (RCDs) zvinoita basa rakakosha mukudzivirira vanhu nemidziyo kubva kumatambudziko emagetsi. Pakati pemhando dzakasiyana dzeRCD dziri pamusika, Type B 30mA RCDs dzinoonekwa zvakanyanya nekuda kwekushandiswa kwadzo kwakasiyana uye hunhu hwadzo. Chinyorwa chino chichaongorora zvinoreva, mabasa, uye mashandisirwo eType B 30mA RCDs kuti zvikubatsire kunzwisisa zvizere mudziyo uyu unokosha wekuchengetedza.

Chii chinonzi RCD?

Mudziyo wemagetsi unoshandiswa kudzivirira kuvhunduka kwemagetsi uye kuderedza njodzi yemoto wemagetsi. Unoshanda nekutarisa magetsi ari kufamba nepawaya dziri mhenyu nedzisina kusimba. Kana ukaona kusawirirana kwemagetsi, uko magetsi ari kudonhedza mvura pasi, unokurumidza kubvisa circuit, zvichidzivirira kukuvara kunogona kuitika uye kukuvara kwesystem yemagetsi.

Tsananguro yeRCD Type B

MaRCD anopatsanurwa mumhando dzakasiyana zvichienderana nekunzwa kwawo uye rudzi rwemagetsi aanogona kuona. MaRCD erudzi rweB akagadzirirwa kuona magetsi anoshandiswa pakuchinjana (AC) uye magetsi anoshandiswa pakushandura magetsi (DC) anoramba aripo. Izvi zvinoita kuti anyatsokodzera kushandiswa mumagetsi anoshandiswa pakugadzira magetsi, akadai sema "solar photovoltaic" (PV) installations uye ma "electrical vehicle (EV) charger stations", uko magetsi anobuda nemagetsi (DC leakage currents) anogona kuitika.

Zita rekuti "30mA" rinoreva mwero wekunzwa kwemudziyo. Chidziviriro chemagetsi cheType B 30mA residual current chinogadziriswa kuti chigumbuke nekuvhura circuit kana chikaona kubuda kwemvura kwe30 milliamperes (mA) kana kupfuura. Mwero uyu wekunzwa unoonekwa sewakakwana kuchengetedza hupenyu hwevanhu nekuti unoderedza zvakanyanya njodzi yekuvhunduka kwakanyanya kwemagetsi.

Kukosha kweRCD Type B 30mA

Kukosha kweType B 30mA RCD hakufanirwe kutaurwa zvakanyanya, kunyanya munzvimbo dzinoshandiswa michina yemagetsi kakawanda. Heano mamwe ezvikonzero zvikuru nei mudziyo uyu uchikosha:

1. Kuchengetedzwa Kwakawedzerwa: Basa guru reType B 30mA RCD nderekusimudzira kuchengetedzeka nekudzivirira kuvhunduka kwemagetsi. Izvi zvakakosha zvikuru munzvimbo dzekugara, dzekutengeserana uye dzemaindasitiri uko vanhu vanogona kusangana nemidziyo yemagetsi.

2. Kudzivirira Moto weMagetsi: RCD Type B 30mA inzira yakakosha yekudzivirira moto wemagetsi nekuona mafungu anobuda anogona kukonzera kupisa kwakanyanya uye moto unogona kuitika.

3. Kutevedzera mitemo: Mitemo yakawanda yekuchengetedza magetsi inoda kuti maRCD aiswe mumabasa chaiwo. Kushandisa Type B 30mA RCD kunovimbisa kutevedzera mitemo iyi, nokudaro kuchiwedzera kuchengetedzeka uye kuderedza mutoro.

4. Kuchinja-chinja: Rudzi rweB 30mA RCD runogona kushandiswa zvakasiyana-siyana uye runogona kushandiswa mumabasa akasiyana-siyana anosanganisira dzimba dzekugara, dzekutengeserana uye zvivakwa zvemaindasitiri. Runokwanisa kuona magetsi eAC neDC, zvichiita kuti ive sarudzo yakakodzera masisitimu emagetsi emazuva ano.

Kushandiswa kweRudzi B 30mA RCD

RCD Type B 30mA inowanzoshandiswa mumhando dzakasiyana siyana dzinosanganisira:

- Masisitimu eSolar Photovoltaic: Sezvo simba rezuva richiva rakakurumbira, RCD Type B 30mA yakakosha kudzivirira kuiswa kwesimba rezuva kubva pakubuda kwemagetsi eDC.

- Nzvimbo dzekuchaja dzeEV: Nekuwedzera kwemotokari dzemagetsi, RCD Type B 30mA yakakosha kuve nechokwadi chekuti nzvimbo dzekuchaja dzeEV dzakachengeteka uko DC current inogona kunge iripo.

- Midziyo yeMaindasitiri: Munzvimbo dzemaindasitiri uko michina mikuru nemidziyo inoshandiswa, RCD Type B 30mA inopa dziviriro yakawedzerwa kubva kumatambudziko emagetsi.

Muchidimbu

Muchidimbu, mudziyo wemagetsi wemhando yeB 30mA (RCD) chinhu chakakosha zvikuru munyaya dzekuchengetedza magetsi. Kugona kwawo kuona mafungu eAC neDC kunoita kuti uve dziviriro inokosha mumagetsi emazuva ano, kunyanya mukushandiswa kwesimba rinogona kushandiswazve uye nzvimbo dzekuchaja mota dzemagetsi. Nekunzwisisa mashandiro uye kukosha kwemudziyo wemagetsi wemhando yeB 30mA, vanhu nemabhizinesi vanogona kutora matanho ekudzivirira kuchengetedzeka uye kuona kuti mitemo yemagetsi inotevedzwa. Kudyara mumudziyo wemagetsi wemhando yeB 30mA haisi chinhu chinodiwa chete, asiwo kuzvipira kuchengetedza hupenyu nepfuma kubva kunjodzi dzemagetsi.
