Description

一种预装式箱式变电站
技术领域
该发明涉及变电站技术领域，尤其涉及一种预装式箱式变电站。
背景技术
变电站一般是服务与区域半径内的用户，但是对于远离变电站的野外施工，或者是电量需求比较大的工矿企业、城市公共建筑或交通施工单位等场所，直接采用变电站的供电服务，不仅需要专门的线路，而且用电成本也较高、现场安全用电风险大、管控难。
所以箱式变电站应运而生，箱式变电站可以直接将10KV的电压转化为可直接使用的0.4KV，使用起来十分的方便，但是箱式变电站在工作的时候，工作人员不能实时了解变压器内部的温度、电压等相关参数，因此难以掌握变压器的工作状态，导致每一次的变压器故障都不能提前进行准备，对施工造成极大的影响。同时，对于需要隔离电压的场所，尤其是山区、海岛等偏远地区，预装式箱式变电站不能对0.4KV的低电压进行转换，也不能同时输出具备0.4KV的普通低电压和隔离电压，智能进一步增设变压器进行电压转换，所以，对特定的用电需求有一定的局限性，进而使用电管理投入更大。
发明内容
针对上述背景技术中说提到的问题，本发明的目的在于提出一种预装式箱式变电站，用以解决传统的箱式变电站不能对其内部的工作状态进行实时监控，对突发问题不能做出及时响应的问题，以及偏远地区的预装式箱式变电站不能对0.4KV的低电压进行转换，也不具备同时输出0.4KV的普通低电压和隔离电压，使用电需求有一定的的问题。
为了达到上述目的，本发明所采取的技术方案如下：包括箱式变电站外壳、安装基座和变压器，所述变压器位于述箱式变电站外壳内部，所述箱式变电站外壳固定于安装基座的上方，所述箱式变电站外壳的内部设有隔板，所述隔板将箱式变电站外壳分为低压室、高压室和变压器室，所述高压室、低压室和变压器室内均设有电压监测模块、电流检测模块、温度监测模块4G发射及远程控制模块和控制器，所述电压监测模块、电流监测模块和温度监测模块均和控制器电性连接，所述低压器室内还设有隔离屏，所述隔离屏的电源输出端依次串接有低压进线智能断路器和智慧用电控制器，所述控制器和智慧用电控制器之间电性连接；
所述安装基座包括矩形分布的砖墙，所述砖墙包括地上部分和地下部分，所述地上部分的上端设有混凝土圈梁，所述混凝土圈梁内设有预埋的槽钢，所述槽钢和箱式变电站外壳的底端固定连接，所述地上部分的侧面上设有便于散热的透气窗，所述地下部分的底部设有线缆孔，所述线缆孔内设有连接线缆，所述连接线缆穿过线缆孔与变电站外壳的底部与变压器连接。
进一步，所述变压室与低压室之间设有电压输出连接通道，所述电压输出通道内设有双电源自动转换开关，所述双电源自动转换开关通过螺丝与所述电压输出通道进行固定，所述双电源自动转换开关的两个输入端与变压器输出端电性连接，所述双电源自动转换开关的输出端与低压室的输入端电性连接，其有益之处在于，
进一步，所述变压室与低压室之间设立的电压输出连接通道中设有4G无线发射器和APP远程遥控开关，与双电源转换开关通过电性连接。
进一步，所述低压室内设有智能电容补偿柜，所述智能电容补偿柜和智慧用电控制器之间电性连接，其有益之处在于，电容补偿柜可补偿功率因数，提高电压质量。
进一步，所述高压室内设有高压控制器、高压真空断路器、电子监控、4G无线转发器和APP远程控制器，以及控制上述元件断开或者是闭合的控制机构，所述控制结构和控制器电性连接，其有益之处在于，通过4G无线转发器和APP远程控制器可实现高压输电的远程控制。
进一步，所述变压器内为三绕组四相，接线方式采用的是Dyn11.Yyn11方式，且低压第一绕组变比为10/0.4KV，低压第二绕组经过隔离屏后变比为0.4/0.4KV，其有益之处在于，四相0.4KV电压经过隔离屏可输出四相隔离电压，在变压器输出端同时引出四相0.4KV电压和四相0.4KV隔离电压等两组电压输出端，实现了一个变压器同时输出0.4KV电压和0.4KV隔离电压，大大减小了变电成本，满足了基建工程的安全用电需求，让输电管理更加方便。
本技术方案的有益之处在于，(1)通过和智慧用电控制器匹配的APP，可对变电站进行远程控制，可远程实现电压、电流、功率的参数设置和监测，且具有配电箱、高压侧、低压侧远程分合闸功能；(2)本技术方案中的变电站可以作为普通的变压器使用，也可作为隔离变压器使用，且二者之间可以相互转换；(3)本技术方案中的变电站为智能化变电站，可通过互联网技术和手机控制，实现实时监测电压、电流、剩余电流、温度和功率等参数，做到突发情况做到早监测和早预防，能够极大的提高用电的稳定性。
