产品功能介绍 Four product features
具有三相线包温度的巡回显示和最高相温度显示切换功能。 1 It has the function of patrol display of the three-phase wire package temperature and the maximum phase temperature display switching function.
可根据设定的开风机温度和关风机温度自动控制风机的开启和关闭，保证干式变压器在正常温度下安全的工作。 2 The fan can be automatically controlled to turn on and off according to the set fan temperature and fan fan temperature to ensure the safe operation of the dry-type transformer at normal temperature. When the highest one-phase temperature in the three-phase wire package temperature exceeds the set temperature of the fan or when the fan is turned on manually, the fan will turn on and the “fan” working indicator on the panel will turn green.
具有超温报警功能。 3 with over-temperature alarm function. 11 、 12 端）输出一个开关信号给远距离的控制柜控制声、光报警。 When the temperature of the highest phase of the three-phase wire package is over-temperature, the temperature control box will issue a buzzer alarm, the "over-temperature" light on the panel will be on, and output through the "over-temperature" output terminals ( 11 , 12 ) of the power board A switch signal gives sound and light alarm to the remote control cabinet.
具有自动跳闸功能。 4 with automatic trip function. 13 、 14 端）输出开关信号，切断电源，保护干式变压器。 When the highest temperature of the three-phase wire package temperature reaches the trip temperature, the temperature control box will issue a buzzer alarm, the "trip" light on the panel is on, and the output switch ( 13 , 14 ) of the power board output switch Signal, cut off power, protect dry-type transformer.
传感器故障时，面板“故障”指示灯会亮 , 箱内有蜂鸣报警 , “故障”输出端（ 9 、 10 端）输出一个开关信号。 5 When the sensor is faulty, the “Fault” indicator on the panel will light up , there will be a buzzer alarm in the box , and the “Fault” output terminals ( 9 , 10 ) will output a switch signal.
指示灯不同颜色代表不同相别故障：黄色代表 A 相，绿色代表 B 相，红色代表 C 相，不亮时，代表传感器正常。 5.1 Different colors of indicator lights indicate different phases: yellow represents phase A , green represents phase B , and red represents phase C. When not lit, it indicates that the sensor is normal.
通过温度显示区显示代码不同区分传感器短路和开路故障：在温度显示区显示 H 表示开路；显示 L 表示短路。 5.2 Differentiate the sensor short circuit and open circuit fault according to the display code in the temperature display area: In the temperature display area, H indicates open circuit; L indicates short circuit.
传感器一相或两相故障时，只根据好的传感器温度信号控制风机，三路传感器同时故障时立即打开风机。 5.3 When one or two phases of the sensor are faulty, only the fan is controlled according to a good sensor temperature signal. When the three-way sensor fails at the same time, the fan is immediately turned on.
可在面板上通过按键直接设定开启风机温度、关闭风机温度、超温报警温度、超温跳闸温度、定时开风机时间及本机通信编号，并且在停电后设置数据不丢失。 6 On the panel, you can directly set the temperature of the fan to turn on, the temperature to turn off the fan, the temperature of the over-temperature alarm, the temperature of the over-temperature trip, the time to turn on the fan and the communication number of the machine, and the setting data will not be lost after the power failure.
具有手动控制风机功能，可手动强制开风机。 7 has the function of manual control of the fan, which can be forced to open the fan manually. This function can also be used to test the fan function.
风机控制型温控箱具有定时开启风机的功能，用户可在面板上进行 0~255 个小时任意设置（当设置为 0 时，表示取消此项功能），定时时间到达后，风机自动运行１分钟后停止。 8 fan control type temperature control box has the function of turning on the fan regularly. Users can set any time on the panel for 0 ~ 255 hours (when set to 0 , it means to cancel this function). When the timer reaches the time, the fan will run automatically. Stop after minutes. 24 小时。 The factory setting is 24 hours.
本温控箱具有“黑匣子”功能，将断电时刻三相温度记录在内存中，以备查询。 9 The temperature control box has a "black box" function, which records the three-phase temperature at the moment of power failure in the memory for future reference. 80 ℃时，不刷新原来记录的温度。 In order to avoid changing the memory data after the power is turned off after the power is turned on again, it is stipulated that the original recorded temperature will not be refreshed when the temperature before the power failure is lower than 80 ℃. 产品操作说明（见图一 Five product operating instructions (see Figure 1 Panel picture)
