產品特點 Features

1.它的防爆原理主要是采用介質隔離點燃源的防爆措施從而達到電器防爆的目的;
2.本產品可根據用戶要求安裝各種普通的檢測儀表、分析儀表、顯示儀表、監視器、微電腦觸摸屏、大功率變頻器以及普通電器元件,對用戶內裝電器元件基本不受限製;
3.它主要由櫃體、自控係統、布氣係統、報警係統、配電係統組成;櫃體由正壓腔和副腔組成,副腔內裝自控係統、報警係統及用戶的進出電纜;正壓腔內裝用戶的配電係統元件;
4.可按用戶要求分別定製成箱式、琴台式和櫃式結構,櫃式又分為上下結構和左右結構。箱式一般采用鋼板焊接而成,表麵噴塑,前開門操作;琴台式和櫃式其櫃架采用標準型材焊接,表麵噴塑,對其各接合麵都經過了特殊的密封處理;前開門操作後開門維修。鋼板材料一般選用GB710-88冷軋鋼板,也可根據用戶要求選用GB3280-84不鏽鋼材質;
5.按進氣方式分為通風型和補償型。通風型為不間斷連續供氣,正壓腔內裝元件的工作熱量可隨氣路帶走,具有很好的散熱功能;補償型為間斷性供氣,正壓腔有良好是密封性,耗氣量小;
6.用戶須提供氣源,要求為:淨化空氣或氮氣,氣源壓力為:0.2Mpa~0.8Mpa;通常用戶現場的儀表風均可滿足要求。也可根據用戶要求,我公司為其設計自供氣係統。

1. The principle adopts medium isolating ignition to avoid explosion of electrical equipments;
2. The products can be fixed with inspection meter, analysis meter, vision meter, monitor, Micro-computer touch screen,highpower transdducer and other electric components, the inside components are unlimited;
3. It is composed of board, body automatic control system, air arrangement ayatem, alarm system and distrbution systen, thebody is composed of positive pressure chanmber and subsidiary chamber, there is a self-control system, alarm system andcable in the subsidary chamber, other distribution system components are in the positive pressure chamber;
4. There are box style, musical plate style and board style, the board style are divided into fluctuated structure and right andleft structure. For the box style, the body is welded by steel plate and sprayed with plastic, operated through the front doorthe board shelf of musical plate and board style is welded by standard profiled bar, surface is sprayed with plastic, the jointplane is handled with sealing, treatment operating from frontal door and maintaining from back door, Normally we selectGB710-88 cold cast steel, also can select GB3280-84 stainless;
5. There are ventilation and compensation entry ways, ventilation entry is used for continue air feed, the heat in pressurechamber can be sent out. It's also with good heat diffusing function, the compensation entry is for dos continuity air feed,the prsee chamber is with perfact sealing and low gas comsumption functions;
6. The user must supply clear air or nitrogen, gas pressure: 02.Mpa~0.8MPa, satisfy the locale requirement, we can designthe gas supply system on request.
