安康干式变压器：矿用安康干式变压器简介

矿用安康干式变压器简介 　　
矿用安康干式变压器可安装在矿井内虽有煤尘和沼气但无爆炸危险的场所。矿用电钻安康干式变压器、照明安康干式变压器可安装在矿井内有煤尘和沼气且有爆炸危险的场所。前者安康干式变压器为油浸式，基本结构与安康干式变压器相同。一次侧没有无励磁调压，调压范围为±5%，二次绕组引出六个端子，可以进行Y，d改接，得到690V /400V或1200V/690V。
为适应矿井下使用，要求安康干式变压器结构坚固，外形低矮。安康干式变压器不带储油柜，油箱内油面以上留有适当的空间，以防箱盖上的通气孔堵塞时，箱内产生过大的压力。油箱的机械强度应能承受98kPa的压力而不水久变形。箱盖内侧要采取防止水冷凝的措施。箱壁两侧焊有电缆盒，供一次、二次电缆引出。
对矿用隔爆型安康干式变压器，用于煤矿中有爆炸危险的场所.这种安康干式变压器都制成密封干式。箱壳的全部接合面均按隔爆要求制作，应能承受785kPa的内部压力。
照明用小型安康干式变压器的电缆通过出线套引出。出线套内设置橡胶垫圈。电缆穿过此垫圈，旋紧出线套后，垫圈即压紧电缆以确保密封。箱壳上焊有托撬，可供水平放置、直立放置和拖动。
容量为100kVA及以上的隔爆安康干式变压器常与隔爆型安康干式变压器箱组合成隔爆型成套移动变电站。隔爆型安康干式变压器的一次绕组具有﹣4%、-8%的分接头，箱内有接线板作分接变换用。二次电压可以做成400V或690V或1200V。箱底设有拖撬，供设备移动用。
为适应坑道运输，要求矿用隔爆型安康干式变压器的高度低，所以其铁柱直径可偏大选取。100kVA及以上隔爆型安康干式变压器通常为H级绝缘，产品按GB3836.1- 4—2000《防爆电气设备制造检验规程》的规定。矿用电钻、照明安康干式变压器的防爆面，应作防锈处理。矿用安康干式变压器允许在与水平面成35°的倾斜巷道内运输。隔爆型安康干式变压器又称防爆安康干式变压器，应进行防潮和隔爆试验。
当需要调整安康干式变压器的输出电压时，对油浸式矿用安康干式变压器，可通过无励华盈非晶合金变压器有限公司磁分接安康干式变压器进行，对矿用成套变电站，则要在外壳上的分接板上进行，如提高二次电压，应接负分接位置，反之则接正分接。矿用安康干式变压器在运愉、贮存和使用时，应防止雨淋和受潮。

Mine Transformer

Mining transformers can be installed although the coal dust and methane, but no possibility of explosion in the mine. Mine with an electric drill transformer, lighting transformer can be installed in the mine the coal dust and methane and the possibility of explosion. Former transformer oil-immersed, the basic structure of power transformers. Primary no excitation voltage regulation range of ± 5%, the secondary winding leads to six terminals can be Y, d grafting to get 690V / 400V or 1200V/690V.
In order to adapt to the mine, the transformer structure is strong, low profile. Transformer without oil storage cabinet, leave the appropriate space above the oil level within the tank, to prevent the lid on the vent is clogged, the box too much pressure. The mechanical strength of the tank should be able to withstand 98kPa of pressure without water for a long time and deformation. Cover the inside to take measures to prevent water condensation. On both sides of the walls of the box welding cable box, for once, the secondary cable leads.
Flameproof Mining Transformer, for there is possibility of explosion in the coal mine. This transformer are made of sealed dry-type. Tank shell joints according to flameproof requirements of production, should be able to withstand the internal pressure of 785kPa.
Lighting with a small transformer cable through the outlet leads. Outlet comprising a set of rubber washers. Cable through the washer, and tighten the qualifying sets, washers, that is, pressed the cable to ensure that the seal. The tank shell welded care pry for the horizontal, upright and drag.
The capacity of 100kVA and above flameproof transformer is often associated with explosio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。n-proof switch box combination into a the flameproof set mobile substation. Flameproof transformer primary winding has a 4% -8% of the tap inside the wiring board for tap change with. The secondary voltage can be made into 400V or 690V or 1200V. Bottom with skid devices for mobile use.
In order to meet the tunnel transport, requires mining flameproof transformer low height, so an iron pillar diameter can be larger selection. 100kVA and above flameproof transformers are usually H-class insulation product according to GB3836.1-4-2000 "explosion-proof electrical equipment manufacturing for the inspection of" requirements. Mine with an electric drill, lighting transformer explosion-proof surface, anti-rust treatment. Mining the power transformer allows an angle of 35 ° tilt roadway transportation. Flameproof transformers also known as explosion-proof transformer should be moisture-proof and explosion-proof test.
When the need to adjust the output voltage of the transformer, transformers, oil-immersed mine can tap non-excited, with a complete set of substation to the mine, will have to tap on the shell panel, such as raising the secondary voltage, should be connected to the negative tap position, and vice versa connected to the positive tap. Mine Transformer transport Discovery, storage and use, to prevent rain and moisture.
