Wanda shi Earthing Transformer?

Mi ne da Earthing Transformer?

Earthing Transformer

Earthing Transformer yana wani abu mai kare na muhimmanci, tushen da ya kamata shine bayar wasu neutral point masu inganci don hukumar da ba ake gane ba, ya fi yawa da amfani da arc suppression coil ko small resistance grounding mode, don in hada da girman ground capacitance current idan an samu fault ta grounding short-circuit a cikin distribution network, zai iya haɗa da kyau ga reliability ta power supply ta system ta distribution.

Earthing Transformer structure

Tushen da Earthing Transformer yake da ita sun hada da iron core, winding, insulation material da shell. Tushen core yana da siyasa da silicon steel sheets masu equal thickness, wanda zai iya haɗa da loss ta magnetic flux density, zama efficiency ta core da kuma bincike output voltage. Winding shi ne mafi muhimmanci a cikin Earthing transformer, tushensa ana divide a biyu: disc winding da long winding. Insulation material yana da muhimmanci don in karkashinsa leakage ta current zuwa winding ko iron core ko case da short circuit. Tushen shell yana da muhimmanci don in karkasha transformer daga mechanical damage da leakage a lokacin da amfani.

Working principle of Earthing Transformer

Principle da Earthing transformer yake da ita shine amfani da magnetic coupling effect ta transformer don in isole neutral point ta wani circuit daga ground, don in bincika safety masu al'adu da kuma in karkashinsa damage a kan electrical equipment. Idan power grid yake da ita a yi nasara, principle da function ta transformer neutral grounding resistance cabinet. Transformer neutral grounding resistance cabinet yana da fadada wajen hada da overvoltage ta power grid da kuma zama safety da reliability ta power grid. Grounding da installation ta 6-66K box-type transformer yana da muhimmanci don in yi karshen da ita kafin a yi amfani da box-type transformer, da kuma grounding yana da muhimmanci don in bincika safe use ta box-type transformer. Ba ni, za ku bayar da function da specific connection method ta box transformer grounding brake. Box transformer grounding brake shine switching device wanda ke separate box transformer daga grounding cable.

Type of Earthing Transformer

Earthing transformer zai iya faɗa saboda filling medium a oil type da dry type; saboda number of phases zai iya faɗa a three phase grounding change da single phase grounding change. A cikin haka, ground transformer zai iya faɗa saboda winding a two-winding ground transformer da three-winding ground transformer.
