1、防爆配電箱的防爆處置
因為防爆配電箱所運用的環境有性氣體或粉塵較多，這就需求防爆配電箱密封防爆，所以它的外殼不能用一般的殼體，必需用規范的防爆腔，把防爆配電箱一切的元件都裝在防爆腔內。在防爆腔門上開一個觀察窗，把顯現有些裝在上面，把發動、中止、調速操控裝在防爆腔門上。
2、防爆配電箱的散熱處置
防爆配電箱散熱疑問因為防爆配電箱的一切元件都裝在隔爆型防爆腔內，空氣不能活動，散熱疑問變成防爆配電箱所要解決的關鍵疑問。在這里咱們采用了一種新的散熱技能-熱管散熱技能。
(1)熱管技能原理熱管是一種具有極高導熱功能的傳熱元件，它經過在全封閉真空管內工質的蒸騰與凝結來傳遞熱量，具有極高的導熱性、杰出的等溫性、冷熱兩側的傳熱面積可任意改動、可遠距離傳熱、可操控溫度等一系列長處。由熱管組成的換熱器具有傳熱效率高、構造緊湊、流體阻損小等長處。
(2)變頻器構造安置咱們將主回路規劃成一個大單元，安裝在長方形防爆腔內后壁，后壁上經過一個過度散熱器與IGBT模塊、整流模塊等發熱元件接合，防爆外殼外壁加焊槽形散熱器，過度散熱器與槽形散熱器經過熱管相連接。變頻器內部發生的熱量就經過防爆腔后壁過度散熱器熱管槽形散熱器發出出去。
Explosion proof, explosion-proof distribution box 1
Due to the use of the explosion-proof box environment more explosive gas or dust,which requires the explosion-proof box sealed explosion-proof housing, so it cannotuse ordinary housing, must use explosion-proof cavity standard, the explosion-proofbox all components are arranged on the explosion cavity. Open a window in the explosion-proof chamber door, the display part is arranged on the top, start, stop,speed control is arranged in the explosion-proof chamber door.
We
Heat treatment 2, explosion-proof distribution box
The explosion-proof distribution box heat problems due to all the components of the explosion-proof distribution box are installed in the flameproof explosion-proof cavity,the air can not flow, the key problems of heat problems become explosion-proofdistribution box to solve. Here we use a heat dissipation technology - the new heat pipe technology.
(1) the technical principle of heat pipe and heat pipe is a heat transfer element withhigh heat conductivity, it closed in vacuum tube refrigerant evaporation and condensation to transfer heat, the heat transfer area has high thermal conductivity,good uniformity, hot and cold sides can be arbitrarily changed, remote heat transfer,can be a the advantages of control temperature. The heat exchanger has theadvantages of high heat transfer efficiency, compact structure, small fluid resistance loss is composed of heat pipe.
(2) converter arrangement we will main circuit design into a large unit, arranged in the rectangular explosion-proof cavity wall, posterior wall by an excessive heat sink and IGBT module, rectifier module heating elements such as joint, explosion-proof enclosure wall welding groove shaped radiator, radiator and excessive trough by heatpipe radiator connection. Transducer internal heat produced by explosion cavity wallexcessive heat pipe radiator radiator gives out groove.
