Abstract

一种分箱型预装式变电站，包括变压器、高压开关、熔断器、高压开关操作室、低压开关室，其特征在于所述的高压开关及熔断器与变压器水平分箱设置，高压开关及熔断器单独设置在高压开关及熔断器油箱内，变压器设置在变压器油箱内。本发明由于将高压开关及熔断器与变压器分设在二个水平分箱内，保证了变压器油的绝缘性能，进而延长了变压器的使用寿命。且由于变压器箱与负荷开关及熔断器箱各自独立，可分别进行检修，不需拆另一个箱，维修安全方便，水平分箱后，变压器油箱、高压开关及熔断器油箱、高压开关操作室、低压开关室四部分之间可按左右前后不同方式并列排布，体积小、结构紧凑、外形美观，生产制造工艺性好，加工制造简单，节省工时。

Description

一种分箱预装式变电站
(一)技术领域
本发明涉及一种输变电设备，具体说是一种分箱预装式变电站。
(二)背景技术
在电子传输与应用中，为将电网中的高压电能转换为低压电能，广泛采用预装式变电站，如美式箱变，因其体积小、全密封、全绝缘、供电方式灵活、安全可靠等优点，广泛应用于城镇配电网中，但其美中不足是高压负荷开关、熔断器与变压器置于同一油箱之中，在操作负荷开关或熔断器动作时产生的电弧会使变压器油产生碳化，易污染变压器油，降低绝缘水平，降低变压器的性能和使用寿命，甚至造成变压器损坏。
为了从根本上解决美式变压器的上述不足，近年来一些企业开始生产分箱式箱变，如西高所设计的分箱式箱变以及东盟、正泰等公司生产的分箱式箱变均为上下层式分箱，下部为变压器箱，上部为负荷开关及熔断器箱，这种分箱式箱变存在如下缺点：
1、安装方式复杂，产品组装时，必须先安装变压器箱。变压器箱安装完成后才能安装负荷开关及熔断器箱。
2、不变于检修，如变压器出现问题或变压器箱出现渗油现象进行检修时，必须先拆开负荷开关及熔断器箱后，才能检修安装变压器箱，这样既费时又费力，非常麻烦。
3、上下分箱由于油箱压力差的作用，如果负荷开关及熔断器与变压器箱之间连接件密封不严，出现渗油时，污染油必将进入变压器箱。
4、产品结构复杂、外形尺寸大，不便于加工，而且费工费时，制造成本高，工艺性差，不美观。
5、低压配出回路少，方案简单。
6、高低压室间无间隔，不符合电气操作规程。
(三)发明内容
为了解决上述现有技术存在的不足，本发明提供一种体积小、结构紧凑、外形美观，维修方便的分箱型预装式变电站。
采用的技术方案是：
一种分箱型预装式变电站，包括变压器、高压开关、熔断器、高压开关操作室、低压开关室，其结构要点在于所述的高压开关及熔断器与变压器水平分箱设置，高压开关及熔断器单独设置在高压开关及熔断器油箱内，变压器设置在变压器油箱内。高压开关操作室与低压开关室并排设置在变压器油箱及高压开关及熔断器油箱的前方。
本发明优点在于：
1、由于将高压开关及熔断器与变压器分设在二个水平分箱内，因而不会使负荷开关或熔断器动作时产生的电弧碳化污染变压器油。保证了变压器油的绝缘性能，进而延长了变压器的使用寿命。
2、由于变压器箱与负荷开关及熔断器箱各自独立，一旦出现问题，可分别进行检修，不需拆另一个箱，维修安全方便。
3、水平分箱后，变压器油箱、高压开关及熔断器油箱、高压开关操作室、低压开关室四部分之间可按左右前后不同方式并列排布，体积小、结构紧凑、外形美观。
4、生产制造工艺性好，加工制造简单，节省工时。
(四)附图说明
图1是本发明一种实施例的结构示意图。
图2是图1的左视图。
图3是图1的右视图。
图4是图3的俯视图。
(五)具体实施方式
请参见图1-图4，本发明的一种分箱型预装式变电站，包括变压器1、高压开关2、熔断器3、高压开关操作室4及低压开关室5。变压器1设置在变器油箱6内。高压开关2及熔断器3设置在与变压器油箱6并排的高压开关及熔断器油箱7内。高压开关操作室4与低压开关室5并排设置在变压器油箱6及高压开关及熔断器油箱7的前方。
