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(jiān)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制；
3.它主要由柜體、自控系統(tǒng)、布氣系統(tǒng)、報警系統(tǒng)、配電系統(tǒng)組成；柜體由正壓腔和副腔組成，副腔內裝自控系統(tǒng)、報警系統(tǒng)及用戶的進出電纜；正壓腔內裝用戶的配電系統(tǒng)元件；
4.可按用戶要求分別定制成箱式、琴臺式和柜式結構，柜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，表面噴塑，前開門操作；琴臺式和柜式其柜架采用標準型材焊接，表面噴塑，對其各接合面都經過了特殊的密封處理；前開門操作后開門維修。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不銹鋼材質；
5.按進氣方式分為通風型和補償型。通風型為不間斷連續(xù)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?。?br /> 6.用戶須提供氣源，要求為：凈化空氣或氮氣，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系統(tǒng)。

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.
