產品簡介
Brief introduction to the products

隨著社會的不斷發展進步,我國城市電網發生了巨大的變化,大多數城市已經形成或正在形成眾多的用電負荷密集區。過去那種從變電站10kV線路(或分支線路)到直接用戶的供電方式已經難以滿足城市發展的要求。因而產生了一種新的供電方式--通過開閉所向用戶供電。但是隨著城市密集化程度的加劇,原有的一些土建型開閉所已受到土地和城市規劃的限制,因此出現了一種更加先進、實用的配電設備--戶外小型智能化開閉所(戶外環網柜)。此開閉所無需土建而且占地面積少,配置非常靈活。供電方式更加可靠.建設安裝、調試時間大為縮短,總體造價降低。
隨著現代工業的發展,對電氣設備控制自動化和智能化程度越來越高,利用現代電子技術、傳感器技術、通訊技術、計算機及網絡技術,將電力設備在正常及事故情況下的監測、保護、控制、計量等集成化,達到良好的管理,已成為一種必然趨勢和發展方向。
智能化小型開閉所(戶外環網柜)是采用借鑒歐洲的開閉所方案,將10kV開關柜、斷路器、負荷開關、電流CT、電壓互感器PT、開閉所FTU、RTU、通信控制終端(CCU、10kV計量及自動抄表、UPS電源及指示儀表等安裝調試好裝入一個可移動、密封、防潮的不銹鋼箱體內。從而實現了城市配電網中一、二次系統的集成化、裝配的模塊化。縮短了建設周期,大大地提高了城市電網運行的可靠性。

   With the continuous development of the social progress, China's urban power grid has changed dramatically.  Most cities have formed or are forming a large number of electricity load-up areas. Past 10kV line from the substation (or branch line) to the direct  user's power supply has been difficult to meet the requirements of urban development, which resulted in a new form of power supply - through the switching substation to supply the users with power. However, with the degree of urban density increases, the original construction of the switching substation is limited by the land and the urban planning, therefore a more advanced and practical power distribution equipment - small-scale outdoor intelligent switching substation (outdoor ring cabinets) appeares. This intelligent switching substation without construction covers only a small area with a very flexible configuration. The power supply is more reliable. The time for installation and debugging is greatly shortened to reduce the overall cost.
   With the development of modern industry, the requirements for automation and intelligence computerization of the electrical equipment are becoming higher and higher.  The utilization of the technology of modern electronic, sensor, communications or computer and network to make the mornitoring, protection, control or measurement under the normal or accident conditions of the electrical equipment for better management into the status of integration has become an inevitable trend and direction of development.
   The intelligent small substation (outdoor ring cabinet) is designed on the basis of European substation programs, which installs the 10kV switchgear, circuit breakers, load switches, current CT, voltage transformer PT, substation FTU, RTU and communication control terminal (CCU, 10kV metering, automatic copy table, UPS power supply and the indicators) in a movable sealed anti-moisture stainless steel tank to realize the integration of the primary and secondary system and the modularization of the assembly. The construction period is shortened. The reliability of the urban power grid operation is greatly enhanced.
