Box type substation is a preassembled and movable power distribution device integrating high-voltage switch, distribution transformer and low-voltage switch cabinet. In addition to the requirements for internal switch and transformer equipment, box type substation box is more important. It is particularly important to select what kind of material, design what kind of structure and shape. It is an economic, reasonable, safe and A scientific power distribution device.

因箱式變電站具有組合機(jī)動、便于運輸、遷徙、裝配便利、施工周期短、運行費用低、占地面積小、無污染、免維護(hù)等優(yōu)點。被廣泛應(yīng)用于城區(qū)、鄉(xiāng)村10110kV中小型變(配)電所、廠礦及流動作業(yè)用變電所的培植與改造，因其易于深入負(fù)荷中間，增添供電半徑，提高開端電壓品質(zhì)，特別適用于村落電網(wǎng)改革。

Because the box type substation has the advantages of combined mobility, convenient transportation, migration, convenient assembly, short construction cycle, low operation cost, small floor area, no pollution, maintenance free and so on. It is widely used in the cultivation and transformation of 10110kv small and medium-sized substations (distribution) in urban and rural areas, factories, mines and mobile operation substations. Because it is easy to go deep into the middle of the load, increase the power supply radius and improve the starting voltage quality, it is especially suitable for the reform of village power grid.

1、技術(shù)可靠

1. Advanced and reliable technology

箱式變電站應(yīng)用及設(shè)計中應(yīng)注意的問題，箱體部分采用技術(shù)及工藝，框架采用標(biāo)準(zhǔn)集裝箱材料及制作工藝，外殼個體采用鍍鋁鋅鋼板。有良好的防腐機(jī)能，保障20年不銹蝕，內(nèi)封板采用鋁合金扣板，夾層采用防火保溫資料，箱體內(nèi)裝配空調(diào)及裝置，設(shè)備運行不受造作景象情形及外界沾染影響，可保證在-40℃～+40℃的卑鄙情形下正常運行。

Problems needing attention in the application and design of box type substation: the box part adopts advanced technology and technology, the frame adopts standard container materials and manufacturing technology, and the individual shell adopts aluminum zinc plated steel plate. It has good anti-corrosion function to ensure that it will not rust for 20 years. The inner sealing plate adopts aluminum alloy gusset plate, the interlayer adopts fireproof and thermal insulation materials, and the box is equipped with air conditioning and dehumidification devices. The operation of the equipment is not affected by artificial scenes and external contamination, which can ensure the normal operation under the despicable condition of - 40 ℃ ~ + 40 ℃.

產(chǎn)品無裸露帶電部分，箱體內(nèi)一次設(shè)備采用單元真空開關(guān)柜、干式變壓器、干式互感器、真空斷路器(彈簧把持機(jī)構(gòu))裝備。河南成套電氣設(shè)備為全絕緣結(jié)構(gòu)，完全能達(dá)到零觸電事故，全站可實現(xiàn)無油化運行，保險性高，二次采用微機(jī)剖析自動化系統(tǒng)，可實現(xiàn)無人值守。

The product has no exposed live parts, and the primary equipment in the box adopts advanced equipment such as unit vacuum switchgear, dry-type transformer, dry-type transformer and vacuum circuit breaker (spring holding mechanism). The complete set of electrical equipment in Henan is a fully insulated structure, which can completely achieve zero electric shock accident. The whole station can realize oil-free operation with high safety. The secondary use of microcomputer analysis automation system can realize unattended.

2、自動化程度高

2. High degree of automation

保護(hù)系統(tǒng)采用變電所微機(jī)剖析自動化裝置，全站智能化設(shè)想。分散裝置，可實現(xiàn) "四遙"即遙測、遙信、遙控、遙調(diào)，每個單元均具有Du立運行功效，繼電保護(hù)功能齊備，河南成套電氣設(shè)備可對運行參數(shù)履行遠(yuǎn)方設(shè)置，對箱體內(nèi)濕度、溫度履行把持，滿足無人值班的請求。

The protection system adopts Substation Microcomputer analysis automation device and the idea of intellectualization of the whole station. The distributed device can realize "four remotes", namely telemetry, remote signaling, remote control and remote adjustment. Each unit has Du vertical operation effect and complete relay protection functions. The complete set of electrical equipment in Henan can perform remote setting of operation parameters and control the humidity and temperature in the box to meet the requirements of unattended.
