风冷控制柜在传统控制方式中,风扇投切的温度限制值是不能改变的,此外,风扇电机的启动和停止温度有一余量,控制器主要由单片机、键盘控制芯片,输出模块、通讯模块以及自动复位电路等组成,不像传统的控制方式中是一个定值,避免了频繁启动的缺陷,故障保护及报警等信号的显示及其与控制中心或调度中心的通讯.
In the traditional control mode of air-cooled control cabinet, the temperature limit value of fan switching can not be changed. In addition, the starting and stopping temperature of fan motor has a margin. The controller is mainly composed of single chip computer, keyboard control chip, output module, communication module and automatic reset circuit. It is different from the traditional control mode. It avoids the defect of frequent startup, the display of signal such as fault protection and alarm, and its communication with control center or dispatching center.
风冷控制柜是针对着变压器的常用冷却方式而设计的智能型控制柜,风冷控制柜可以实现远方自动和就地手动控制方式,并可以把各种信息上传显示和下行控制设定,对变压器整个冷却系统实现最优控制,达到节能和延长散热器使用寿命的目的.风冷控制柜配有人机界面,可实时观察变压器的状态,可根据负荷、温度的变化设置冷却系统参数.风冷控制柜采用模块化设计,控制逻辑变更简便,具有安全性强、使用寿命长、设备维修费用低等特点.
Air-cooled control cabinet is an intelligent control cabinet designed for the common cooling mode of transformer. The air-cooled control cabinet can realize remote automatic and local manual control mode, and can upload and display all kinds of information and set downlink control. It can realize optimal control of the whole cooling system of transformer to save energy and prolong the use of radiator. The air-cooled control cabinet is equipped with man-machine interface, which can observe the state of transformer in real time and set the parameters of cooling system according to the change of load and temperature. The air-cooled control cabinet adopts modular design, and the control logic is simple and easy to change. It has the characteristics of strong safety, long service life and low maintenance cost of equipment.
