Description

变电站电容器室正压式通风降温结构
技术领域
[0001] 本发明涉及一种通风降温结构,尤其是一种变电站电容器室正压式通风降温结构,属于变电站降温的技术领域。
背景技术
[0002]目前变电站电容器室普遍采用的降温措施为:在电容器室外墙的上方安装风机,在电容器室外墙的下方开设进风百叶窗。所述降温措施虽能排去电容器室内部分热量,但却存在以下问题:1)、新风气流组织不合理,使进入到电容器室的新风只能流经部分电容器就被排出室外,导致远离进排风口的电容器设备得不到通风散热。2 )、风机运行时会带进大量的灰尘,雾雨天还会带进水汽,电容器积尘会影响其散热,同时遇潮时,使电容器裸露部分和外瓷件等引起闪络。3)、当室内温度较低时风机还在连续全速运行,不利于节能。4)、风机运行时噪音较大。
发明内容
[0003] 本发明的目的是克服现有技术中存在的不足,提供一种变电站电容器室正压式通风降温结构,其结构紧凑,有效改善电容器柜的运行条件,降低故障概率,提高设备运行和供电的可靠性。
[0004] 按照本发明提供的技术方案,所述变电站电容器室正压式通风降温结构,包括位于电容器室内的下部且通过电容器室内下部的通风墙孔进风的通风降温主机,在电容器室内的墙体上部设有用于将空气排出的排风窗;通风降温主机包括用于输出新风的新风出口以及用于输出制冷除湿空气的制冷除湿风口。
[0005] 所述通风降温主机包括用于将室外新风压入的新风风机以及用于制冷除湿的制冷除湿机构,所述新风风机与制冷除湿机构均与通风降温控制器连接。
[0006] 所述制冷除湿机构包括位于电容器室外的制冷除湿室外机以及与所述制冷除湿室外机连接配合的冷风风机与蒸发器,蒸发器位于冷风风机的下方,在冷风风机上方设有回风口,所述回风口与冷风风机间设有回风过滤网。
[0007] 所述新风风机上设有用于降噪的消声器,新风风机的进风口设有新风过滤网,新风风机的出风口与通风降温主机上的新风出口连通。
[0008] 所述通风降温控制器与室内温湿度传感器、室外温湿度传感器以及烟雾传感器连接。
[0009] 所述通风降温控制器与数据通信模块连接。
[0010] 本发明的优点:
1、在电容器室的通风墙孔与通风降温主机连通,利用新风风机产生的相对较高的静压,将新风压入电容器室,根据室内设备等布局,设定新风风口的方向,以使得新风同电容器柜进行热交换后汇集至排风窗排出室外。
[0011] 2、当连续阴雨或夏季连续高温时段,依靠新风无法控制室内温湿度时,启用通风降温主机内的制冷除湿机构,通过制冷除湿机构能实现对电容器室内的制冷除湿,以确保电容器柜的运行状态可靠性。
[0012] 3、通过室内外空气置换,确保电容器室内有害气体的排出,且对进入的室内空气实行高效过滤,同时室内保持弱正压,室外灰尘无法从门窗等缝隙进入,从而保证电容器室内空气的洁净。新风风机与消声器配合,以使得电容器室内的噪声小于等于55dB。
[0013] 4、通风降温控制器与数据通信模块连接,实现电容器室内通风降温主机的自我管理功能,无需人工干预。通风降温控制器能根据室内排风口处的温度值计算出所需散热风量,来控制风机速度,解决当室外空气温度较低时风机高速运行的无谓功耗问题。具备无线、有线网络通信,管理人员可以在任何地点、任何时间实时了解电容器室的运行环境情况和获得报警信息,以及时发现故障,快速处理,提高电容器等设备运行的安全性和可靠性。

[0026] 所述新风风机18上设有用于降噪的消声器19,新风风机18的进风口设有新风过滤网17,新风风机18的出风口与通风降温主机6上的新风出口 9连通。本发明实施例中,消声器19位于新风风机18的下方,新风风机18的进风口通过新风过滤网17与通风墙孔5连接,通过新风过滤网17能有效滤除进入电容器室I内的杂物,确保新风的洁净。消声器19与新风风机18的出风口连接,通过消声器19能确保电容器室I内的静音效果。
[0027] 所述通风降温控制器16与数据通信模块连接。通风降温控制器16通过数据通信模块能与智能终端连接,数据通信模块可以采用GPRS、3G模块、4G模块或WIFI模块等,通风降温控制器16能通过数据通信模块将电容器室I内的各种环境参数等均发送至智能终端内,管理人员根据环境参数以及报警信息实现对电容器室I的有效监控,可及时发现故障,保证安全电容器室I内的安全可靠性。此外,管理人员还可以通过数据通信模块向通风降温控制器16发送控制命令,以调节通风降温主机6内新风风机、制冷除湿机构的工作状态,确保电容器室I的环境参数达到所需的状态。所述报警信息是指烟雾传感器4检测到有烟雾室,通风控制器16产生的报警信号。
