变压器免维护智能呼吸器

变压器在线监测变压器免维护智能呼吸器是用于油浸式变压器、互感器、有载分接开关或其它充有绝缘液的电气设备所使用的空气除湿及净化装置，变压器免维护呼吸器安装在互感器储油柜的进气口上，当变压器或互感器在运行过程中由于油温变化而使油体积发生涨缩时，迫使储油柜内的气体通过吸湿器产生呼吸，空气通过吸湿器下部的过滤器及充满硅胶的玻璃罐体进入变压器，可保证吸入的气体干燥（水分被干燥剂吸附）及洁净（粉尘杂质被过滤器阻挡），以保持变压器油的清洁和绝缘强度。

变压器在线监测———变压器免维护智能呼吸器

产品概述

经过一段时间的使用后，变压器免维护呼吸器内的硅胶达到饱和状态，颜色发生变化，需要更换或干燥处理，同时这种变色的硅胶易污染不环保。而免维护呼吸器使用新型无污染的干燥剂代替含有氯化钴的变色硅胶，并且当硅胶吸湿饱和后可以通过使用某些方法（如加热法）将硅胶中的水分析出，从而能对干燥剂进行反复利用。

主要功能

1、使用变压器身内的空气通过装置与外界空气相通，以保持器身内外气压相等，防止因压力过高而造成的变压器喷油。

2、通过干燥、吸收的作用，防止潮湿空气直接进入变压器，使变压器绝缘油保持良好的电气性能，防止因变压器的绝缘强度被破坏而造成短路、放电、绕组烧毁。

工作原理

变压器正常运行时，外部空气由变压器免维护呼吸器吸入，经过干燥后进入变压器油枕。变压器免维护呼吸器对内部的空气湿度进行连续监测并将测量结果传给电子控制装置。当空气湿度超过程序设定值时，表明干燥剂暂时失去吸水能力呈饱和状态，并且压力传感器监测到为正压时，此时传感器会激活硅胶中的加热元件，变压器免维护呼吸器加热系统自动启动，以使环保型硅胶再生。双筒装置则利用电磁阀切换通气阀，使再生过程产生的热量和蒸汽在玻璃内壁凝露后通过呼吸器底部不锈钢过滤网流出，以保证再生过程快速、有效。

当环境温度低于程序设定值，底部辅助加热模块自动启动以防止过滤装置低温时产生凝露或者冰冻，从而确保呼吸器保持良好的状态。

当免维护呼吸器发生装置故障时（如控制系统或加热系统故障），装置控制盒外部指示灯指示灯红灯报警，以便运行人员巡视检查，可以通过预设触点开关发生远方报警信号，同时所有状态参数（温度、湿度、加热状态、故障状态等参数）均可以通过RS485接口输出，实现远方通讯，以实现呼吸器状态的远程监控。同时，客户可以根据需要定制选配符合61850通信规约的网络输出接口模块，以实现变压器呼吸器设备状态信息接入变电站主站通信系统。
