张家界干式变压器：箱式变电站的结构

箱式变电站的结构 　　
1.概述
统一设计的箱式变电站典型结构按各种接线设备所需空间设计，采用环网、终端供电线路方案.根据运输的要求设计有整体式和分单元拆装式。
箱体采用钢板夹层(可填充石棉)和复合板两种，顶盖喷涂彩砂乳胶或特殊油毡。吊装方式为上吊式，装配式变电站体积小，采用底吊环形式，为监视、检修、更换设备需要设计通用门，既可双扇开启，也可单扇开启，张家界干式变压器室设有两侧开门的结构。
（1）高压设备联锁，符合防误要求，设计原到以强制性闭锁为主，提示性闭锁为辅。
(2)箱体的通风与散热，箱体有封闭或半封闭式结构，高、低压室全为封闭式。
(3)噪声防护箱体材料、结构连接的方式、百叶窗的设什都应具有较好的隔声性、减振性，张家界干式变压器本身嗓声为48dB(距0.3m处侧).装入箱内距0.2m实测为39dB,满足箱体高、低压室0.22m处为35dB和环境保护法规定小于45dB的要求。
(4)基础及电缆坑道，箱式变电站的基础结合进出电缆的需要做电缆坑，其四璧砖彻24cm，灰砂2cm，按组合布置外廊尺寸留槽钢基础框，设备箱体确定后.箱体底部主结构与基础外部地脚螺栓连接.张家界干式变压器下部基础填有卵石并与高、低压室隔离。高、低压设备部分箱底是封闭的，电缆是由电缆孔穿入，用异形胶皮护套封口套严，箱底则有维护活动盖板，电缆施工时可以掀开。

Box-type substation structure

1 Overview
Unified design of a typical box-type substation wiring structure according to a variety of equipment for space design, the use of ring network, the terminal power supply line program, according to the requirements of the design of transport and sub-unit integral removable.
Laminated steel plate box (can be filled with asbestos) and composite panels are two kinds of sand cover spray latex or special linoleum. Lifting means for the hanging type, assembly-type substation small size, the use of the end rings in the form, for the monitoring, maintenance, replacement of equipment need to design a common door, either double-leaf opening, but also on a single fan, transformer room has a door on both sides of the structure .
(1) high-voltage interlock device, in line with anti-error requirements, the design of the original to a mandatory lock-based, supplemented by tips atresia.
(2) ventilation and cooling box, box has closed or semi-enclosed structure, high and low pressure chamber are all closed.
(3) noise protection enclosure materials, structure the way connection, the blinds should be set even has good sound insulation, vibration damping, sound voice transformer itself is 48dB (from 0.3m at the side). Into the box measured from 0.2m to 39dB, to meet the box high and low pressure chamber 0.22m at the 35dB and 45dB华盈非晶合金变压器有限公司是具备生产220KV电压等级变压器的现代化机械制造企业，公司注册资本8800万元，现有员工300余人，占地面积300余亩，公司拥有各种生产和使用设备100余台，产品工艺水平高，检测设备齐全，企业管理严格，产品质量可靠。求精务实，开拓创新，为用户提供完美的变压器解决方案，满足各层次客户的需求。主要产品有非晶合金变压器，干式变压器，SH15-M系列非晶合金变压器，非晶合金铁芯配电变压器，SCRBH15非晶合金干式变压器，SGBH15非晶合金变压器（10KV级），SCRBH15非晶合金卷铁芯干式变压器，35kv非晶干变变压器 35kv非晶油变变压器，超强过载能力变压器、电力变压器、油浸式变压器、矿用变压器、整流变压器、电炉变压器、特种变压器、等等，并提供新能源发电的升压及并网解决方案。我公司除生产以上10多个系列200多个品种，600多种规格的变压器外，还向用户提供非标特种产品的设计、制造。以上产品符合GB1094、GB/T6451、GB6450标准和等效IEC（国际电工委员会）标准。 less than the environmental Protection Act requirements.
(4) foundation and cable trenches, box-type substation based out of the cable needs to be done with the cable pit, the four bi brick Toru 24cm, gray sand 2cm, arranged by portfolio size to remain outside the channel base frame gallery, equipment cabinet confirmed . bottom of the box outside the main structure and foundation anchor bolts connecting transformer filled with gravel and the lower base and high and low pressure isolation room. High and low voltage equipment part of the bottom is closed, the cable from the cable hole penetration, with a strict set of shaped rubber sheath seal, bottom cover, there are maintenance activities, construction of the cable can be opened.
