直流電流與交流電流相比較，不存在周期性的電流數(shù)值過(guò)零點(diǎn)，因此，傳統(tǒng)接觸器開(kāi)斷電路時(shí)，觸頭之間產(chǎn)生的電弧較為強(qiáng)烈，燃弧時(shí)間也比較長(zhǎng)，以便充分釋放電路中剩余的能量。電弧的燃燒產(chǎn)生高溫和強(qiáng)光，對(duì)觸頭表面有嚴(yán)重的燒蝕作用，觸頭材料在多次開(kāi)斷之后逐漸流失，觸頭電磨損嚴(yán)重時(shí)，導(dǎo)致直流接觸器報(bào)廢，不能開(kāi)斷電路。?[1]?電力電子技術(shù)得以迅猛發(fā)展，人們將電力電子元件應(yīng)用到直流接觸器中，巧妙的創(chuàng)造出一種混合式直流接觸器，使得直流接觸器向智能化、可控化邁進(jìn)了新的一步。這種混合式接觸器利用傳統(tǒng)直流接觸器在閉合導(dǎo)通狀態(tài)下觸頭接觸電阻小、導(dǎo)通壓降小的優(yōu)點(diǎn)，將由反并聯(lián)晶閘管和控制模塊單元共同組成的無(wú)觸點(diǎn)開(kāi)關(guān)并聯(lián)在傳統(tǒng)直流接觸器觸頭上。這種無(wú)觸點(diǎn)的電力電子開(kāi)關(guān)分?jǐn)嚯娐窌r(shí)不產(chǎn)生電弧，這就避免了傳統(tǒng)接觸器中電弧對(duì)觸頭材料的電磨損，也就大大增加了觸頭的使用壽命和可靠性。?[1]?直流接觸器永磁機(jī)構(gòu)3TH42620XB03TH42620XC23TH42620XD03TH42620XF03TH42620XG23TH42620XH03TH42620XJ13TH42620XJ23TH42620XK23TH42620XL13TH42620XL23TH42620XM03TH42620XM13TH42620XM23TH42620XN23TH42620XP03TH42620XQ03TH42620XR23TH42620XS03TH42620XU03TH42621XB43TH42621XC43TH42621XE43TH42621XF43TH42621XM43TH42621XP43TH42621XV43TH42621XW43TH42710XB03TH42710XC03TH42710XD03TH42710XG03TH42710XG13TH42710XH03TH42710XJ13TH42710XJ23TH42710XK13TH42710XK23TH42710XL03TH42710XL13TH42710XM03TH42710XM13TH42710XM23TH42710XN13TH42710XP03TH42710XQ03TH42710XR13TH42710XR23TH42710XS03TF44110XL23TF44110XM03TF44110XM23TF44110XN23TF44110XP03TF44110XQ03TF44110XQ23TF44110XU03TF44110XV03TF44111XB43TF44111XC43TF44111XE43TF44111XF43TF44111XG43TF44111XM43TF44111XV43TF44220XB03TF44220XC13TF44220XC23TF44220XD03TF44220XD23TF44220XF03TF44220XG03TF44220XG23TF44220XH03TF44220XJ23TF44220XK13TF44220XK23TF44220XL23TF44220XM03TF44220XM23TF44220XN13TF44220XN23TF44220XP03TF44220XP23TF44220XQ03TF44220XR03TF44220XR23TF44220XU03TF44220XV03TF44221XB43TF44221XE43TF44221XF43TF44221XM43TF44221XP43TF44221XV43TF44221XW43TF45110XB03TF45110XC23TF45110XF03TF45110XG03TF45110XG13TF45110XG23TF45110XJ23TF45110XM03TF45110XM23TF45110XN23TF45110XP03TF45110XQ03TF45110XQ23TF45110XR03TF45110XU03TF45110XV03TF45111XB43TF45111XC43TF45111XE43TF45111XF43TF45111XG43TF45111XM43TF45111XP43TF45111XV43TF45220XB03TF45220XC23TF45220XD03TF45220XF03TF45220XG03TF45220XG23TF45220XH03TF45220XJ23TF45220XL03TF45220XL23TF45220XM03TF45220XM13TF45220XM23TF45220XN13TF45220XN23TF45220XP03TF45220XP23TF45220XQ03TF45220XQ23TF45220XU03TF45220XV03TF45221XB43TF45221XC43TF45221XE43TF45221XF43TF45221XG43TF45221XM43TF45221XP43TF45221XV43TF45221XW43TF46110XB03TF46110XC23TF46110XD03TF46110XF03TF46110XG03TF46110XK23TF46110XL23TF46110XM03TF46110XN23TF46110XP03TF46110XQ03TF46110XU03TF46220XB03TF46220XC03TF46220XC13TF46220XC23TF46220XD03TF46220XD23TF46220XF03TF46220XG03TF46220XG23TF46220XH03TF46220XK13TF46220XK23TF46220XL03TF46220XL23TF46220XM03TF46220XN13TF46220XN23TF46220XP03TF46220XP23TF46220XQ03TF46220XR03TF46220XR23TF46220XU03TF46220XV03TF46221XB43TF46221XF43TF46221XG43TF46221XM43TF46221XW43TF46331XB43TF46331XF43TF46331XM43TF46440XF03TF46440XG03TF46440XL23TF46440XM03TF46440XN23TF46440XQ03TF46440XQ23TF46440XR03TF46440XV03TF47110XB03TF47110XC23TF47110XF03TF47110XG03TF47110XG23TF47110XH03TF47110XK23TF47110XL23TF47110XM03TF47110XN23TF47110XP03TF47110XQ03TF47110XU03TF47220XB03TF47220XC23TF47220XD03TF47220XD23TF47220XE03TF47220XF03TF47220XF000KC03TF47220XG03TF47220XG13TF47220XG23TF47220XH03TF47220XJ23TF47220XK13TF47220XK23TF47220XL03TF47220XL13TF47220XL23TF47220XM03TF47220XM23TF47220XN13TF47220XN23TF47220XP03TF47220XP23TF47220XQ03TF47220XQ23TF47220XR23TF47220XU03TF47220XV03TF47221XB43TF47221XF43TF47221XG43TF47221XM43TF47221XV43TF47221XW43TF47221XY803TF47331XB43TF47331XF43TF47331XG43TF47331XM43TF47440XF03TF47440XG03TF47440XL23TF47440XM03TF47440XM23TF47440XN23TF47440XP03TF47440XQ03TF48110XB03TF48110XC23TF48110XF03TF48110XG03TF48110XG23TF48110XL23TF48110XM03TF48110XN23TF48110XP03TF48110XQ03TF48110XV03TF48220XB03TF48220XC23TF48220XD03TF48220XD23TF48220XF03TF48220XF000KC03TF48220XG03TF48220XG13TF48220XG23TF48220XH03TF48220XJ13TF48220XJ23TF48220XK23TF48220XL13TF48220XL23TF48220XM03TF48220XN13TF48220XN23TF48220XP03TF48220XP23TF48220XQ03TF48220XQ23TF48220XR03TF48220XR23TF48220XS03TF48220XU03TF48220XV03TF48221XB43TF48221XF43TF48221XM43TF48331XB43TF48331XF43TF48440XF03TF48440XG03TF48440XG23TF48440XM03TF48440XN23TF48440XQ03TF48440XQ23TF49110XD03TF49110XF03TF49110XG03TF49110XK23TF49110XL23TF49110XM03TF49110XN23TF49110XQ03TF49110XU03TF49220XB03TF49220XD23TF49220XF03TF49220XG03TF49220XG13TF49220XG23TF49220XH03TF49220XH23TF49220XK23TF49220XL03TF49220XL13TF49220XL23TF41110XM03TF41110XN23TF41110XP03TF41110XQ03TF41110XQ23TF41110XV03TF41111XA43TF41111XB43TF41111XC43TF41111XE43TF41111XF43TF41111XM43TF41111XP43TF41111XV43TF41200XC03TF41200XC13TF41200XC23TF41200XD03TF41200XD23TF41200XE03TF41200XH03TF41200XJ13TF41200XJ23TF41200XK13TF41200XK23TF41200XL03TF41200XL13TF41200XM03TF41200XM13TF41200XM23TF41200XN23TF41200XP03TF41200XP13TF41200XP23TF41200XQ23TF41200XR03TF41200XR13TF41200XR23TF41200XS03TF41200XS13TF41200XS23TF41200XU03TF41200XV03TF41201XB43TF41201XF43TF41220XB03TF41220XC23TF41220XD03TF41220XF03TF41220XG03TF41220XG13TF41220XG23TF41220XH03TF41220XL13TF41220XL23TF41220XM03TF41220XN23TF41220XP03TF41220XP23TF41220XQ03TF
