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，变压器油箱、高压开关及熔断器油箱、高压开关操作室及低压开关室四部分之间，可按左右前后不同方式并列排布。
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、熔断器油箱7的前方。
