型温度控制器
一、用途及原理
WTZK-02型温度控制器(BWY-02型温度控制器),适用于测量变压器油温或其他的液体、气体和蒸气的温度,并能在被测温度达到和超过设定值时发出接点信号。
本仪表主要用于500KV A以上的变压器油温的测量和控制。
控制器的主要结构是由温包(感温探头)毛细管和弹性元件组成。
这三个部件构成的密封系统内充灌了感温介质、当被测温度发生变化时,温包内的液体压力随着发生变化,通过毛细管的传递使表头的弹性元件产生一个相对应的位移量,这个位移经机械放大后便可指示出被测温度,并带动微动开关动作输出信号。
二、主要技术参数
1.测量范围:0~100℃
2.指示精确度:1.5级
3.开关特性
(1)开关设定精度:±3℃
(2)开关差:6±2℃
(3)开关额定负荷:AC220V、1.5A
4.温包尺寸:ф14×150
5.温包安装尺寸:外螺纹M27×2
6.表头安装尺寸:3孔ф6 144×210
7.开关在仪表出厂时标准设定值:第一上限55℃
第二上限80℃
如果用户需调整开关设定值,可打开表盖,转动表盘上旋钮设定针即可,然后按原样合上表盖。
三、安装和使用
1.温度设定:打开表盖,转动旋钮设定针即可(一般不用再设定)。
2.接线:打开表盖,将电缆线从引线接点穿入,按图2要求接线。
电缆线推荐使用KW4×1.5控制电缆。
接线后拧紧引线接头处螺母,不得松动。
表盖按原样合好,均匀旋紧四只螺钉。
温控器表头安装前应先完成安装接线和开关设定两项工作。
图2 接线端子板
3.温控器安装
将螺钉穿过隔振板,将仪表固定在仪表板上,多余纺织管部分应盘为ф300mm以上的环圆状,每隔300mm应用护套做适当固定,以免损坏整台仪表。
4.温包安装
温包的插入深度必须≥150mm。
温包安装前应在安装孔内注满变压器油,然后慢慢插入温包并拧紧M27×2安装接头。
安装接头上有一个M18×1.5空心螺栓,其作用是用于调节温包的插入深度,正确的安装方法是全部拧出M18×1.5空心螺栓,在引长管上缠绕填料(如麻丝或生料带等),用户在完全拧紧空心螺栓前调整好温包的插入深度(尽可能选最大插入深度),然后拧紧空心螺栓。

1Warning!EN61326-1EN60825-11. Safety notices Before using the thermodetector, please read the manual carefully. Do not use any solvent to clean the thermodetector. Safety symbols:Important information prompt for dangerComplies with European CE safety specificationThe instrument complies with the following standards:Do not align the laser to human eyes or reflective surface2. Notes When the ambient temperature changes in a sudden, it is required to place the thermodetector in the environment for 30 minutes , and measure when internal and external temperatures of the thermodetector coincide.Try to avoid any electromagnetic field caused by electric welding and induction heating.Do not place the thermodetector close to or on a high temperature object.Keep the thermodetector clean, and avoid dust from entering the tube.23.

Measurement methods1. Set the upper limit of the instrument alarm:Press and hold the Mode key for 2 seconds, to enter instrument setting, and press MODE key to shift to alarm upper limit setting, in this case, Hi is displayed in the instrument function indication zone, and the alarm upper limit is displayed in the zone. Press ▲/▼ key to increase or decrease the alarm value, and long press ▲/▼ key to accelerate the increase or decrease of the set value.2: Set the low alarm value of the instrumentPress and hold the Mode key for 2 seconds, to enter instrument setting, and press MODE key to shift to alarm lower limit setting, in this case, Low is displayed in the instrument function indication zone, and the alarm lower limit is displayed in the zone. Press ▲/▼ key to increase or decrease the alarm value, and long press ▲/▼ key to accelerate the increase or decrease of the set value.3: Set the instrument radiancePress and hold the Mode key for 2 seconds, to enter the instrument setting, and press the MODE key to shift to the instrument radiance setting, in this case, the instrument radiance indication zone flashes. Press the ▲/▼ key to increase or decrease the radiation value, and long press the ▲/▼ key to accelerate the increase or decrease of the set value.44: Set the instrument temperature unitPress and hold the MODE key for 2 seconds, to enter the instrument setting, and press the MODE key to shift to the instrument temperature measurement unit, the unit symbol on the display flashes, and press the ▲/▼ key to change the unit symbol.5: Exit the settingPress the trigger or long press the MODE key, to exit the instrument setting.6: Turn on/off laserPress the key to turn on or off laser, and the instrument will display the laser symbol7:Turn on or off back-lightPress the key to turn on or off back-light.8: Non-contact temperature measurementAim the thermodetector at the object, and hold the trigger, to conduct continuous measurement of temperature. After displaying stably, release the trigger, and the5When holding the trigger, the secondary display of the instrument will display the maximum value of the measured temperature.When the measured value is greater than the upper limit of high alarm or the measured value is less than the lower limit of low alarm, the red alarm indicator will turn on to alarm.6. Target distance ratio (D:S ratio)The thermodetector has a certain visual angle and visual field, as shown in the following figure.The measured target Tube Light-sensitive componentIn order to guarantee the measured object fills in the visual field of the thermodetector, which means the thermodetector only "sees" the measured object rather than other objects. Larger objects may cause larger temperature measurement distances; for smaller objects, the measurement distances must be close. The ratio of measurement distance to the measured target (D:S) is 12:1, as shown in the following figure:677. RadianceThe radiance characterizes the ability of an object to radiate infrared ray. Larger radiance will lead to stronger radiation ability on the object surface.Radiance of the majority of organic matters or metal oxidized surfaces ranges between 0.85 and 0.98. The radiance of the thermodetector is 0.95 by default. During measurement, set the radiance of the instrument the same with the radiance of the measured object. During measurement, please pay attention to the impact of emissivity on measurement results.The following table is the radiance reference table.Measured surfaceRadiance Aluminum Oxidized0.2~0.4A3003alloy (oxidized)0.3A3003alloy (coarse)0.1~0.3Brass Polishing0.3Oxidized0.5 Copper Oxidized0.4~0.80.6Electrical terminalboardHastelloy0.3~0.8 Ferro-nickel Oxidized0.7~0.95Abrasive blasting0.3~0.6Electropolishing0.15Iron Oxidized0.5~0.9Rust0.5~0.7 Iron(casting)Oxidized0.6~0.95Unoxidized0.2Fusion cast0.2~0.3 Iron(casting)passivation0.9Lead Coarse0.4Oxidized0.2~0.6 Molybdenum oxidation0.2~0.68Nickel oxidation0.2~0.5 Platinum black0.9 Steel Cold rolling0.7~0.9Grinding steel plate0.4~0.6Polished steel plate0.1 ZincOxidized0.1 Asbestos0.95 Asphalt0.95 Basalt0.7 Carbon(unoxidized)0.8~0.9 Graphite0.7~0.8 Silicon carbide0.9 Ceramics0.95 Clay0.95 Concrete0.95 Cloth0.95 Glass plate0.85 Gravel0.9519LCD displayColor LCD display D:S12:18.

四、工作原理:4.1 温度控制:当被测环境温度低于设定温度下限时,本仪器启动电加热设备开始加温,此时加热指示灯亮,温度升至比下限温度设定值高回差值时,即:W测≥W下限+回差,停止加温。
当被测环境温度高于设定温度上限时,本仪器启动降温设备(如风机或空调)开始降温,此时排风指示灯亮,温度降至比上限温度设定值低回差值时,即:W测≤W上限-回差,停止降温。
4.2 湿度控制:当被测环境湿度超过设定湿度上限时。
如果当前温度较高,即:W测≥W下限+(W上限-W下限)×3÷4,采用降温(或排风,视具体地区采用不同设备)抽湿,此时排风指示灯亮;抽湿过程中,如果温度低于下限温度+2度后,自动转为加热降湿;当降湿过程中温度高于上限温度-2度后,自动转为降温抽湿,直至湿度低于设定下限值为止。
当被测环境湿度超过设定湿度上限时。
如果当前温度较低,即:W测<W下限+(W上限-W下限)×3÷4,采用加热降湿,此时加热指示灯亮,降湿过程中,如果温度高于上限温度-2度后,自动转为降温抽湿;当温度低于下限温度+2度后,自动转为加热降湿,直至湿度低于设定下限值为止。

本仪表在电力变压器行业中主要用于500KVA 以上的变压器油温的测量和控制。
仪表外形见图1。
二、主要技术参数1.测量范围:0~100℃(或20~120℃)2.指示精确度:1.5级3.开关数量及特性(1)开关数量:2只(2)开关设定精度:±3℃(开关设定与启动的差值)(3)开关差:6±2℃(开关闭合与断开的差值)(4)开关额定负荷:AC220V、3A4.温包尺寸:ф14×1505.温包安装螺丝:外螺纹M27×26.表头安装尺寸:3孔ф6.2 144×210(见图1)7. 开关设置为常开状态,在仪表出厂时标准设定值:第一上限(K) 55℃(闭合)1) 80℃(闭合)第二上限(K2如果用户需调整开关设定值,可打开表盖,请按温度设定程序操作(详见安装和使用4.),完成后按原样合上表盖。
三、安装和使用1. 表头的安装用三颗M6的螺丝,将仪表呈垂直方向固定在仪表安装板上,连接温包之间的毛细管,每隔300mm应有适当的固定,避免毛细管的损坏。
将多余的毛细管部分盘成ф300mm的环圆状,亦有同样的固定。
2.温包的安装温包安装前应先在安装座孔内注满导热油(变压器油),拧松温包上的空心螺栓,使其与安装接头分离。
慢慢将温包插入安装座,任安装座内的导热油溢出,然后拧紧安装接头。
将温包引长管尽可能插入最深,同时在密封垫片以下的引长管上缠绕适当的填料(如生料带),然后将空心螺栓与安装螺丝拧紧,确保安装座内的油与外界完全隔离。
温包插入安装座后应使温包在变压器油的水平线以下,以确保测温的准确性(见图2)。
XMK-2型温度控制器
XMK-2型温度控制器------------------------------------使用说明书功能:1、被控对象的温度测量和显示;2、温度上、下限的设定被控设备的开停控制;3、制冷和制热两种控制模式选择;4、温度传感器故障显示(开路或短路);5、用户可修正显示温度;6、全量程0.1℃分辨率;7、制冷模式时压缩机停机延时3分钟保护;一、功能和操作:1.通电温度显示:控制器通电后显示“---”,约3秒后显示实际温度测量值。
2.参数设定:(1)进入设定状态:为了防止误操作和避免闲人玩弄,必须连按“set(设置)”键三下,才能进入设定状态。
(2)控制器进入设定状态后,首先显示上限设定提示符为“H--”(高,即下限),首次按“▲”健或“▼”键显示上限设定值,再次按“▲”健或“▼”键改变上限设定值;此时可按“▲”健或“▼”键改变设定值,直至符合要求(设定为负值时,负号闪烁);再次按“set(设置)” 显示下限设定提示符为“L--”(低,即下限),设定方法同上;再次按“set(设置)”显示显示修正温度提示符为“C--”,设定方法同上;再次按“set(设置)” 显示显示控制模式提示符为“J--”,首次按“▲”健或“▼”键显示当前控制模式(CC:制冷,HH:制热),按“▲”健选择制冷控制模式,制冷模式指示灯点亮,按“▼”键选择制热控制模式,制热模式指示灯点亮。
(3)当上限设定值≤下限设定值,本控制器自动调正上限设定值=下限设定值+l℃。
(4)退出设定:15秒之内不按任何一个键,控制器自动退出设定状态,并自动保存设定值,显示屏上仍显示温度测量值。
敬告一:修改设定值后必需再按一下“set”键,使设定值得以确认并储存,否则控制器不能按新的设定值进行控制。
敬告二:若设定完后未经延时退出就(断电)关机,新设定值将得不到保存,控制器仍按原设定值运行。
(5)显示屏显示温度=实际温度+温度修正值,一般情况下,修正值设定为0。

当温包受热时,温包内感温介质受热膨胀所产生的体积增量,通过毛细管传递到弹性元件上,使弹性元件产生一个位移,这个位移经机构放大后指示出被测温度并带动微动开关工作,从而控制冷却系统的投入或退出。
BWY(WTYK)-802A、803A温控器采用复合传感器技术,即仪表温包推动弹性元件的同时,能同步输出Pt100热电阻信号,此信号可远传到数百米以外的控制室,通过XMT数显温控仪同步显示并控制变压器油温。
也可通过数显仪表,将Pt100铂电阻信号转换成与计算机联网的直流标准信号(0~5)V、(1~5)V或(4~20)mA输出。
