Thyristor Converter: fasali na aiki da kuma ci gaban al'amurra

A nazarin da kaddarorin semiconductors yarda don ƙirƙirar sababbin abubuwan da aka rayayye yi amfani da daban-daban lantarki. Yana bayyana a hankali more iko na'urorin da cewa ba ya sauya sheka haihuwarka na babban iko.

A misali mai kyau na wannan shi ne wani thyristor Converter. Tun da aka kafa, da ya fara ji dadin wani da suka cancanta shahararsa tsakanin zanen kaya. Wannan na'urar da aka yadu a yi amfani daban-daban lantarki haihuwarka: Starter da baturi da caja, waldi inji, heaters, inverters, sarrafawa rectifiers , da dai sauransu Wannan ba wani cikakken jerin na'urorin a cikin abin da thyristor Converter da ake amfani.

A tsawon lokaci, akwai iko kida ta hanyar abin da ya zama zai yiwu don sarrafa gudun lantarki Motors ko dumama shuke-shuke. Da suka kasance rayayye amfani a samar, da kuma a wasu lokuta ma ya maye gurbin gargajiya tsarin a lokacin "janareta-motor" (GD).

Inganta iko haihuwarka ƙwarai ƙãra AMINCI wadannan na'urorin. Iko thyristor Converter iya iko da zumudi na yanzu, ko rajista kai tsaye a cikin anga sarkar engine. Duk da haka, da farko tsarin da bugun jini-lokaci iko (IFSB) sau da yawa nuna hali erratically. Wannan zai iya haifar da da, a ce, a "yi-kan" na inverter da fitarwa na da ikon gyara na tsarin. A tsarin tushe, kuma, ya fita yawa da za a so. A tsawon lokaci, wadannan matsaloli ne da wani abu da suka gabata. Akwai m na'urar lantarki da aka tam sarrafawa da kuma, idan ya cancanta, a kare m obalodi thyristor Converter. Shi ne kuma dole a lura da high dace, mai kyau maintainability da kuma kananan size wannan na'urar tare da girmamawa ga madadin tsarin.

Amma kuma da kyau yi, irin wannan na'urorin ya mallaki wasu shortcomings dangane da ikon kewaye:

• A rabo daga amsawa da kuma aiki ikon lokacin da yin amfani da su ba ya canja ga mafi alhẽri ga sauran wadata cibiyar sadarwa gefe. Don ajiye cos shi% yi amfani da compensators na amsawa ikon a kan tushen da capacitors.

• A ta aiki, thyristor converters quite dauke da ƙazantar ikon cibiyar sadarwa na high mita tsangwama. musamman RC-haihuwarka ana amfani da su wajen magance wannan hasara.

Tare da yin amfani da musamman tsara na'urorin iya canza wani siga kamar mita na mains. Ana amfani da a shigar da gagarumar wuta, a lokacin da kafa wani karfe ko wasu lantarki shigarwa. Wannan aiki da aka yi da wani musamman ɓullo da wannan manufa thyristor mita Converter. Its halitta ya muhimmanci inganta data kasance a lokacin daga karfe aiki fasahar a wuraren aiki.

A tsawon lokaci, madadin na'urorin da cewa aiki gaba ɗaya a kan sauran ka'idoji. Suka ci gaba da makircinsu kan high-ikon IGBT-transistors cewa ana amfani da su iko da Motors na low kuma matsakaici iko. Suna da hankali da maye gurbin wanda aka rabu amfani da tsarin.
