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.

因箱式变电站具有组合机动、便于运输、迁徙、装配便利、施工周期短、运行费用低、占地面积小、无污染、免维护等优点。被广泛应用于城区、乡村10110kV中小型变(配)电所、厂矿及流动作业用变电所的培植与改造，因其易于深入负荷中间，增添供电半径，提高开端电压品质，特别适用于村落电网改革。

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、技术先进安全可靠

1. Advanced and reliable technology

箱式变电站应用及设计中应注意的问题，箱体部分采用先进技术及工艺，框架采用标准集装箱材料及制作工艺，外壳个体采用镀铝锌钢板。有良好的防腐机能，保障20年不锈蚀，内封板采用铝合金扣板，夹层采用防火保温资料，箱体内装配空调及除湿装置，设备运行不受造作景象情形及外界沾染影响，可保证在-40℃～+40℃的卑鄙情形下正常运行。

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 ℃.

产品无裸露带电部分，箱体内一次设备采用单元真空开关柜、干式变压器、干式互感器、真空断路器(弹簧把持机构)先进装备。河南成套电气设备为全绝缘结构，完全能达到零触电事故，全站可实现无油化运行，保险性高，二次采用微机剖析自动化系统，可实现无人值守。

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、自动化程度高

2. High degree of automation

保护系统采用变电所微机剖析自动化装置，全站智能化设想。分散装置，可实现 "四遥"即遥测、遥信、遥控、遥调，每个单元均具有Du立运行功效，继电保护功能齐备，河南成套电气设备可对运行参数履行远方设置，对箱体内湿度、温度履行把持，满足无人值班的请求。

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.
