Yadda ake magance matsalar lokacin high-frequency quenching kayan aiki yana samun kurakurai

1. Abun kuskure Kayan aiki yana gudana akai-akai, amma yawancin KP thyristors da fuses masu sauri suna ƙone yayin aikin kariya na yau da kullun na yau da kullun. Domin a saki makamashin na’urar mai santsi zuwa grid ɗin wutar lantarki yayin kariyar wuce gona da iri, gadar gyara tana canzawa daga yanayin gyarawa zuwa yanayin inverter. A wannan lokacin, idan α = 150?, yana iya haifar da inverter mai aiki ya juya ya ƙone yawancin thyristors da fuse mai sauri. , Canjin yana tafiya, kuma akwai ƙarar ƙarar fashewar ɗan gajeren lokaci, wanda ke haifar da babban tasiri na halin yanzu da ƙarfin lantarki a kan na’urar, wanda zai lalata na’urar a lokuta masu tsanani.

2. Al’amarin kuskure Na’urar kashe wutar lantarki mai ƙarfi tana gudana akai-akai, amma kayan aikin ba su da tabbas a kusa da wani wuri a cikin babban ƙarfin wutar lantarki, DC voltmeter yana girgiza, kuma na’urar tana tare da sautin ƙararrawa. Wannan yanayin yana da yuwuwa ya sa gadar inverter ta juye ta ƙone thyristor. . Irin wannan kuskuren ya fi wuya a kawar da shi, kuma yawanci yana faruwa ne lokacin da wani ɓangare na kayan aiki ya taso a ƙarƙashin matsin lamba:

(1) Sako da sukurori na haɗin gwiwar mashaya tagulla suna haifar da ƙonewa;

(2) Oxidation na babban haɗin gwiwa na mahaɗar kewayawa yana haifar da ƙonewa;

(3) Sukudi na diyya capacitor wiring tara sako-sako da, haifar da ciki fitarwa juriya capacitor na ƙonewa diyya capacitor to igating da sha capacitor;

(4) Sashin rufewa na radiyo mai sanyaya ruwa yana da datti sosai ko carbonized zuwa ƙasa;

(5) Ƙunƙarar induction na jikin tanderun ya saba da tanderun harsashi. Tazarar da ke tsakanin jujjuyawar murɗa na jikin tanderun ya yi kusa sosai, kuma ginshiƙin induction na madaidaicin tanderun yana ƙonewa saboda yawan zafin da ake fitarwa na carbonization.
