產(chǎn)品特點
防爆插接裝置由插座和插頭兩部分組成。插頭由阻燃塑料外殼、5個銅觸頭、1個定位觸頭和隔爆銅套構(gòu)成。插座外殼采用鑄鋁合金制成，內(nèi)裝斷路器，具有短路和過載保護功能。開關(guān)由外部操作手柄操作，操作機構(gòu)與插座有聯(lián)鎖保護裝置，插頭插入前，開關(guān)只能處在分斷位置，手柄不能被操作，當插頭插牢后，手柄才能旋向合位置。當旋到合位置時，插頭不能被拔出，保證了運行可靠性。插座上觸頭套與插頭之間設(shè)有特制網(wǎng)狀鍍銀磷銅片，使其在大電流量接觸良好，并不發(fā)熱。接線腔與元件腔分開，接線腔設(shè)有5個接線柱，電纜布線須配電纜夾緊密封接頭，內(nèi)外接地鋼管或電纜布線。
Features
The plug-socket device is made of plug and socket.Plug consists of flame resistant plastic housing, five copper pins,one locating pin and flameproof brass sleeve.Housing of socket is made of aluminum alloy,in which there is circuit breaker with functions of short circuit and overloading protection. The device could be operated with outer-handler, plug is interlocked with operation mechanism.Before inserting plug into socket,the switch is only in the state of and the lever could not be operated. When the plug is inserted into socket firmly, the lever could be operated to on / off, and the plug could not be pulled out, so it is safe. There are five holes in socket,which matches with the five pins of plug. There is brass net sheet ring in every hole respectively so no over heating occurs with heavy current. Wiring compartment is isolated from function compartment . There are five terminals in the function compartment, three ones are phase wires, one is zero conductor, the fifth is earthing wire.There is one earthing bolt on housing. Wiring with conduit or cable.
