QYDL-BWD3K330干式变压器温控器产品功能Product functions

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 transformer‟s 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A、B、C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6．手动启动关闭风机功能：按风机键，风机启动，再按风机键，风机关闭。如手动风机启动后没有手动关闭风机，则风机启动约15分钟后自动关闭。

Manual fan starting and stopping function: Pressing the fan button, the fan will start up, pressing the fan button again, the fan will stop. When the fan is manually started, it will stop automatically after about 15 minutes if it is not stopped manually.

QYDL-BWD3K330干式变压器温控器7．风机定时检测功能：为避免风机长时期不启动而锈蚀堵转损坏，特设有风机定时检测功能，定时启动时间可自由设定范围为0-199小时，到设定值时风机启动一次，启动时间约2分钟。输入“000”时则取消该功能。 Periodic fan detection function: In order to prevent long time stopping and the consequential corrosion and blockage, a special fan detection function is provided, the selectable scope of the periodic starting time is from 0 to 199 hours, when the time reaches the preset starting value, and the fan will start up automatically and keep running for about 2 minutes. Inputting “000” will cancel the function.

QYDL-BWD3K330干式变压器温控器8．控制功能自检：可模拟输入温度值而使温控器作出相应的功能表现。

Control function self diagnose: You can input analog temperature value, and let the thermostat performs corresponding functions.

QYDL-BWD3K330干式变压器温控器9．“黑匣子”功能：可记录温控器断电时的变压器三相绕组温度，以及本机的工作状态。 “Back box” function: The thermostat can record the temperature value of the three-phase windings in the transformer in case of power failure.

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 0～200 风机启动温度T2 Fan start temperature T2 100 0～200 超温报警温度T3 Over heat alarm temperature T3 150 0～200 超温跳闸温度T4 Over heat trip temperature T4 180 0～200

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。

Note：1. 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.
