經(jīng)過不斷的驗(yàn)證、改進(jìn)再驗(yàn)證、再改進(jìn),
仿威圖機(jī)柜的功能也在不斷的完善,在其他領(lǐng)域的科技升級(jí)和創(chuàng)新,也不斷的融入到仿威圖機(jī)柜的生產(chǎn)技術(shù)中。那么仿威圖機(jī)柜都有哪些保護(hù)功能?
After continuous verification, improvement and verification, and improvement, the function of the imitation Weitu cabinet is also constantly improved, in other fields of science and technology upgrading and innovation, but also constantly into the production technology of the imitation Weitu cabinet. So what are the security protection functions of the imitation Weichart cabinet?
低壓斷路器保護(hù)功能:低壓斷路器在電路中除起控制作用外,還具有一定的保護(hù)功能,如過負(fù)荷、短路、欠壓和漏電保護(hù)等。
Low voltage circuit breaker protection function: low voltage circuit breaker in the circuit in addition to play a control role, but also has a certain protection function, such as overload, short circuit, undervoltage and leakage protection.
短路保護(hù):由內(nèi)部螺旋狀導(dǎo)體和銜鐵組成;過載過流保護(hù):由雙金屬片和機(jī)械脫扣裝置構(gòu)成;失壓保護(hù):由失壓線圈,銜鐵和機(jī)械脫扣裝置組成。
Short circuit protection: composed of internal spiral conductor and armature; Overload and overcurrent protection: composed of bimetal sheet and mechanical release device; Loss of pressure protection: it is composed of loss of pressure coil, armature and mechanical release device.
隔離開關(guān)保護(hù)功能
Isolation switch protection function
維護(hù)人員的人身:在電氣設(shè)備檢修時(shí),提供一個(gè)電氣間隔,并且是一個(gè)明顯可見的斷開點(diǎn),用以保障維護(hù)人員的人身。
Safety of maintenance personnel: During the maintenance of electrical equipment, an electrical separation is provided and a visible disconnect point is used to ensure the personal safety of maintenance personnel.
短路保護(hù)功能:負(fù)荷開關(guān)具有在非故障條件下,接通或分?jǐn)嘭?fù)荷電流的能力和一定的短路保護(hù)功能。
Short circuit protection function: load switch has the ability of connecting or breaking load current and certain short circuit protection function under non-fault conditions.
總線保護(hù)作用:斷路器在斷開位置,只能先合母線側(cè)隔離刀閘,才能合線路側(cè)隔離刀閘。此種接線不僅防止帶負(fù)荷拉、合隔離開關(guān),而且能防止違反開關(guān)、刀閘操作原則的違規(guī)操作。
Bus safety protection: in the open position of the circuit breaker, only the isolation switch on the bus side can be closed before the isolation switch on the line side. This kind of connection not only prevents pulling and closing the disconnecting switch with load, but also prevents illegal operation in violation of the operating principles of switch and switch.
負(fù)荷開關(guān)保護(hù)功能
Load switch protection function
一般裝有簡(jiǎn)單的滅弧裝置,但其結(jié)構(gòu)比較簡(jiǎn)單。其工作過程是:分閘時(shí),在分閘彈簧的作用下,主軸順時(shí)針旋轉(zhuǎn),一方面通過曲柄滑塊機(jī)構(gòu)使活塞向上移動(dòng),將氣體壓縮;另一方面通過兩套四連桿機(jī)構(gòu)組成的傳動(dòng)系統(tǒng),使主閘刀先打開,然后推動(dòng)滅弧閘刀使弧觸頭打開,氣缸中的壓縮空氣通過噴口吹滅電弧。
Generally equipped with a simple arc extinguishing device, but its structure is relatively simple. The picture shows a pneumatic high-pressure load switch, its working process is: when the brake, under the action of the brake spring, the main shaft rotates clockwise, on the one hand, through the crank slider mechanism to move up the piston, the gas compression; On the other hand, through the transmission system composed of two sets of four-link mechanism, make the main knife open first, and then push the arc extinguishing knife to open the arc contact, the compressed air in the cylinder through the nozzle to blow out the arc.
仿威圖機(jī)柜的保護(hù)功能并非某一個(gè)部件單一存在的,而是很多部件相互協(xié)同,有些部件具備相同或者相似的保護(hù)作用,兩種部件結(jié)合起來,就又增加了一道保護(hù)的保險(xiǎn)。更多內(nèi)容來此
