Design and structure。 The housing, cover plate and door of the switchgear must be made of metal while the body of imported aluminum plated zinc plate and with sufficient strength. The cover plate needing not to be opened in normal operation and maintenance should not be able to be opened, removed or moved without tools while the cover plate and door needing to be opened in normal operation and maintenance should be able to be opened or moved with interlock device set to ensure the safety of the operator. 開關(guān)柜應(yīng)設(shè)必要的觀察窗，便于觀察運行中的設(shè)備。 The switchgear should be set with excellent ventilation system so that the temperature rise inside the cabinet will not exceed that required by every module。 The inside of the switchgear is set with antidamp heater, which will automatically power off when the switchgear is put into operation or automatically power of when the switchgear stops (switchgear status display in set) and whose power supply is 1phase 220VAC. 開關(guān)柜的防護等級包括觀察窗、通風(fēng)窗、排風(fēng)口在內(nèi)不低于IP30。 The insulation strength of insulated ponents and the clear distance between conductors and to the ground when only air is used as insulation medium must ply with the requirements of DL40491 (Technical Conditions for the Order of Indoor AC Highvoltage Switchgears). 同類型的刀開關(guān)部件（小車、隔離插頭等），必須具有良好的互換性。 The breaker and operation mechanism of the highvoltage switchgear should be installed firmly in order to avoid affecting the normal work of the instruments and relays in the cabinet. 測量儀表繼電保護裝置和二次回路圖 Diagram of measuring meters, relay protective devices and secondary circuits 測量儀表、繼電保護裝置與高壓帶電部分應(yīng)完全隔離并有足夠的距離，以保證在高壓帶電部分不停電的情況下進行工作，人員不致觸及運行中的
