It has powerful built-in WATCHDOG function, a SCM with upper power down detection module, so that the thermostat can continue to work at different conditions without the need of installing a reset button.

QYDL-BWD3K330E干式变压器温控箱完善的检测保护功能。温控器可自动判断传感器短路及开路故障。通过设置还可定时启动风机,以避免风机长时间不工作而锈蚀堵转造成损坏。温控器也可通过模拟输入温度值来检测温控器的控制功能。  

Complete detection and protection functions. The thermostat can automatically diagnose the short circuit of the sensor and the problem of the open circuit. The fan can set to timing starting mode to run the fan periodically so as to avoid stopping too long a time which may cause rust and result in blockage. You can also input temperature value in analogue mode to detect the control function of the thermostat.  

I 2QYDL-BWD3K330E干式变压器温控箱C总线调整与存储技术。温控器内无需采用电位器,而是采用先进的I 2C总线调整技术调校温度精度,彻底解决了因使用电位器而可能产生的漂移及接触不良的缺点,使温控器可长期可靠地运行。  I 2C bus line modulating and memory technology. The thermostat adopts I 2C bus line modulating technology, instead of potentiometer, to modulate temperature precision. This eliminates the defect of drift and poor contact resulted from the use of potentiometer, ensuring a long and stable operation of the thermostat.

  1.检测并巡回显示变压器三相绕组温度或只显示变压器三相绕组温度最高的一相绕组温度。巡回显示时每相显示约6秒。  

Detects and displays alternately the temperature of the three- phase windings in the transformer, or only displays the winding with the highest temperature among the transformers three- phase windings. In alternating display mode, each phase is displayed for about 6 seconds each time.

QYDL-BWD3K330干式变压器温控器2.故障声光报警:传感器故障时相应的ABC相指示灯亮,同时风机启动,温控器内发出„滴滴‟声并接通报警触点。LED显示„X-HO‟或„X-LO‟,„X‟表示故障相位。  Light and sound fault alarm: In case the sensor has troubles, the corresponding indicator lamp for A, B, and C phase will glow, at the same time, the fan starts to run, the thermostat gives out alarm sound and connect the alarming contact. The LCD displays X-HO or X-LO‟,„X indicates phase.

QYDL-BWD3K330干式变压器温控器3.风机启动和关闭功能:当变压器三相绕组中有一相绕组温度达到设定的风机启动温度值时风机自动启动,风机启动时风机指示灯亮。当变压器三相绕组中没有一相绕组温度大于设定的风机关闭温度值时风机自动关闭。

Fan stating and stopping function: When the temperature of any of the three-phase windings in the transformer reaches the preset automatic start value of the fan, the fan will start to run automatically and the fan indicator lamp glows. When the temperature values of all the three-phase windings in the transformer are lower than the automatic stop value of the fan, the fan will stop to run automatically.

QYDL-BWD3K330干式变压器温控器4.超温报警功能:当变压器三相绕组中有一相绕组温度达到设定的超温报警温度值时温控器发出声、光报警,并接通报警输出端子,提供一组开关信号给远方的控制柜。   Overheat alarm function: When the temperature of any of the three-phase windings in the transformer reaches the preset overheat alarm value, the thermostat will give out sound and light alarms, and connect the alarm output terminal to provide a group of on off signals to the far end control cabinet.

QYDL-BWD3K330干式变压器温控器5.超温跳闸功能:当变压器三相绕组中有一相绕组温度达到设定的跳闸温度值时,温控器接通跳闸输出端子,提供一组开关信号给远方的控制柜,启动跳闸电路。

Overheat trip function: When the temperature of any of the three-phase windings in the transformer reaches the preset overheat trip value, the thermostat will connect the trip output terminal to provide a group of on off signals to the far end control cabinet, which will start up the trip circuit.  

(为防止因偶然因素触发跳闸特设有约5S延时)。

(In order to prevent unnecessary trip by occasional factors, a 5-second delay is designed.)

QYDL-BWD3K330干式变压器温控器10.所有温度设置均可通过面板上的轻触键直接设置。为避免闲杂人员随意更改设置,温控器设有密码,只有密码输入正确才能设置,否则只能查看而不能设置,并且温控器发出一声„嘀‟的报警声。设置温度范围见下表。

All the temperature values can be set with the touch buttons on the control panel. In order to prevent irrelevant people to change the set values, the thermostat is design to use password, you can set the value only when you input the correct password, otherwise, you can only see the value and cannot change it, if you do not input correct password, the thermostat will gave out an alarm sound. The scope of the setting temperature value is shown in the following table

温度T  Temperature T 出厂设定温度(℃) Factory set temperature() 可调温度范围(℃) Adjustable temperature scope() 风机关闭温度T1  Fan stop temperature T1 80 0200  风机启动温度T2  Fan start temperature T2 100 0200  超温报警温度T3  Over heat alarm temperature T3 150 0200  超温跳闸温度T4  Over heat trip temperature T4  180 0200

注:1、设置时应遵循T4>T3>T2>T1+4 4为风机启停的最小回差值)     2、出厂设定温度值可根据用户的需求来设定。                  

Note1. To set, follow the procedure: T4>T3>T2>T1+4 4 is the minimum return difference

for fan start and stop    

     2. The factory set temperature value can be made according to customers requirement.
