產品特點
- 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；
- 結構上采用上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；主柜為正壓室，防護等級為IP54， 副柜為輔助室，安裝正壓控制系統，保護等級為IP31；
- 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，正壓腔有良好的密封性，耗氣量小；
- 保護裝置齊全，控制柜設有換氣送電聯鎖裝置，只有達到規定的換氣時間后， 方能自動送電，并有高、低壓自動聲光報警及壓力下限、開門自動斷電、緊急手動斷電等安全聯鎖保護。
- 密封性能可靠，殼體采用多重密封保護，保壓時間長，節約運行費用。
- 本柜采用電纜溝座安裝形式，用戶需配備保護氣體氣源。
- 產品內部可裝檢測儀表、分析儀表、顯示儀表、低壓電器、變頻器、軟起動器或計算機控制系統，可作為*信號處理系統及*控制系統。制造時，用戶必須提供完整的電氣系統圖，控制系統內裝材料清單。
- 可多臺并柜。
- 可根據用戶所提供的電氣原理圖生產。
The 1 principle of its proof is mainly using dielectric isolation source of ignition proof measures so as to achieve the purpose of electrical explosion-proof;
2 Structure Based on user requirements can be customized into a case type, respectively, desk and cabinet structure, the cabinet is divided into upper and lower structure and a control structure. Box type generally adopts a welded steel, surface spray, front door operation; desk and cabinet the cabinet frame adopts the standard section welding, spray the surface of the joint surface, a special sealing treatment; front door after door repair operation. Plate material general selection of GB710-88 cold rolled steel, according to user requirements can also use GB3280-84 stainless steel material; a main cabinet for the positive pressure chamber, the protection class is IP54, deputy cabinet for mounting auxiliary chamber, positive pressure control system, protection grade IP31;
By 3 air inlet mode is divided into the ventilation type and compensation. Ventilation for continuous supply, positive pressure cavity. The components work heat with gas path to take, and has good heat dissipation function; compensation type intermittent supply, the positive pressure chamber has good sealing property, small gas consumption;
4 comprehensive protection devices, control cabinet is provided with ventilation electrical interlocking device, only to reach the required ventilation time, can automatic transmission, and is high, low pressure automatic alarm and pressure, open the door, automatic power-off emergency manual power-off safety interlock protection.
5 reliable sealing performance, shell uses multiple sealing protection, pressure holding time, and saving operation cost.
The 6 cabinet with cable ditch base installation forms, user should be equipped with protective gas source.
7 it can inner-install inspecting instrument, analysis instrument, instrument display, low-voltage electrical appliances, inverter, soft starter or computer control system, can be used as a central signal processing system and central control system. Manufacturing, the user must provide a complete electrical system, control system and inner material list.
8 multiple and cabinet.
9 according to the user provide the electrical schematic diagram of production
