本安與隔爆的區(qū)別
Difference between intrinsic safety and flameproof
本安與隔爆型控制柜通常都安裝在安全區(qū)。本質(zhì)安全型防爆技術(shù)通常采用PLC控制系統(tǒng)，柜內(nèi)配備安全柵，將危險(xiǎn)區(qū)返回的信號(hào)線經(jīng)過安全柵處理后再接入PLC輸入/輸出模塊。目前國內(nèi)通常對(duì)PLC輸入信號(hào)采用本安型防爆技術(shù)，可將危險(xiǎn)區(qū)的輸入電流限制在2mA以下，因?yàn)殡娏骱苄。瑥谋举|(zhì)上講是安全的。
Intrinsically safe and flameproof control cabinets are usually installed in safe areas. The intrinsically safe explosion-proof technology usually adopts PLC control system. The cabinet is equipped with safety barrier. The signal line returned from the dangerous area is processed by the safety barrier and then connected to the PLC input / output module. At present, intrinsically safe explosion-proof technology is usually used for PLC input signal in China, which can limit the input current in dangerous area to less than 2mA, because the current is very small, which is essentially safe. =
而PLC輸出信號(hào)因?yàn)閮r(jià)格和其它因素，通常采用隔爆型防爆技術(shù)，輸出信號(hào)線通常采用鎧裝電纜，穿入水煤氣管，接入隔爆型防爆電器，例如防爆電機(jī)等，安裝中要求從控制柜到最終設(shè)備之間都要進(jìn)行密封處理，將電纜與危險(xiǎn)區(qū)進(jìn)行隔離。
Because of the price and other factors, the PLC output signal usually adopts the flameproof explosion-proof technology. The output signal line usually adopts armored cable, which is penetrated into the water gas pipe and connected to the explosion-proof electrical apparatus, such as explosion-proof motor. During installation, sealing treatment is required between the control cabinet and the final equipment to isolate the cable from the dangerous area.
隔爆型與本安型是兩種不同的防爆電器，前者內(nèi)部可能有燃爆源（如燈泡）但采取隔爆措施達(dá)到安全目的，后者不會(huì)達(dá)到爆燃能量（電壓不高于 12 V，電流不大于 100mA，比如熱電阻，屬于本質(zhì)安全型）。雖然如此，防爆電器通常在安全場合和非安全場合分界處都安裝有安全柵。壓力變送器基于不同工作原理也可以有以上兩種區(qū)別。 防爆的等級(jí)根據(jù)使用場合選擇。
Flameproof type and intrinsically safe type are two kinds of different explosion-proof electrical appliances. The former may have internal explosion-proof source (such as bulb), but the latter will not achieve deflagration energy (voltage not higher than 12 V, current not greater than 100 Ma, such as thermal resistance, belonging to intrinsically safe type). However, the explosion-proof electrical appliances are usually installed with safety barriers at the boundary between safety and non safety occasions. Pressure transmitter can also have the above two differences based on different working principles. The explosion-proof grade is selected according to the application situation.
