交直流箱式变电站 技术领域
本实用新型属于变电站结构技术领域, 尤其涉及一种交直流箱式变电站。 背景技术
近些年, 我国引进了欧式箱变 (筒称欧变)和美式箱变 (筒称美变)技 术, 填补了箱变技术的空白, 为我国电气工程发展建设提供了新装备, 欧变 和美变的主要结构无外乎 "品字型" (如图 1 )和 "目字型" (如图 2 )。 即在 一个平台上设有不同功能的三个隔室: 变压器室、 高压室、 低压室。
它的主要功能在于将交流电从高压变换到低压、 或将交流电从低压变换 到高压, 然而人们并未满足当前的技术现状, 继续普遍关注箱变的发展和进 步, 尤其是在继续探索新的功能、 新的结构、 新的用途。
欧变和美变的问世为工程建设提供了一种全新的电气装备, 满足了市场 的部分需要,但它的局限在于只能将电能从交流低电压转换成交流高电压(升 压)或是将交流高电压转换成交流低电压 (降压) 。 实用新型内容
为此, 本实用新型所要解决的技术问题是提供一种交直流箱式变电站, 以克服现有存在的不足。
为解决上述技术问题, 本实用新型采用如下的技术方案:

所述低压室、 高压室和变压器室呈品字形分布在箱体的一侧空间内, 所 述逆变器室单独分布在箱体的另一侧空间内。
在本实用新型的一实施例中, 所述逆变器室内的逆变器设备横向面对面 分布成两排, 逆变器设备的背面靠箱体的箱壁, 两排逆变器设备的正面之间 具有操作通道。
在本实用新型的另一实施例中, 所述逆变器室的逆变器设备纵向排列成 两排, 两排的逆变器面对面设置, 逆变器设备的背面与箱体的箱壁之间间隔 具有维护通道, 两排逆变器的正面之间具有操作通道。
在本实用新型的另一实施例中, 所述逆变器室内的逆变器设备纵向面对 面分布成两排, 逆变器设备的背面靠箱体的箱壁, 两排逆变器设备的正面之 间具有操作通道。
以上就是本实用新型的交直流箱式变电站, 该箱式变电站能够实现直流 低电压( 1000V及以下)向交流高电压( 35KV及以下)转换,增加了箱式变电 站的直流输入, 填补了目前的箱式变电站只能从交流转换交流, 不能从直流 转换交流的功能性空白。 附图说明
