优质双控水位保护器哪里找高质双控水位保护器哪里找


双控水位保护器
Double-control Aater Level Protector
产品主要参数 Main parameters of products:
额定电流(Rated current):4A/250VAC
感应电流(Inductive current):1A/250VAC
热电流(Thermal current):5A/250VAC
(开关未动作时,连通端子之间可承受的电流)
最大动作力(Maximum operating force):0.25牛
最小释放力(Maximum release force):0.25牛
触发点(Contact point):14.7±0.4mm(从开关孔中间量起)
差动行程(Differential travel):0.35mm
触点间隙(Contact clearance):0.4mm
A组:接通距离为38mm,Connected,the distance is 38mm;
      断开距离为39mm,Disconnected,the distance is 39mm.
B组:接通距离为22mm,Connected,the distance is 22mm;
      断开距离为23mm,Disconnected,the distance is 23mm.
C组:在无任何浮力的环境下,
     开关浮子上平面到壳底面的距离为39mm
When there is no floating power,the upper surface of floater of floater is 39mm from the bottom surface of vessel.
总高度(Total height):98mm  推杆长:71mm
行程距离(Travel distance):26mm
安装孔直线距离(Straight line distance between installation holes):48mm


产品特性:

该产品主要是用于液位保护,当器皿中水位超过标准水位时,来切断电源电池,从而达到保护目的。
Characteristi cs of product:
This product is mainly used to protect the liquid level.It can switch off the power when the water level in the vessel is higher than the standard water level to reach the protection purpose.
绝缘电阻:
     带电部分与非带电件之间的绝缘电阻≥100MΩ
Insulation resistance:
    Insulation resistance between the live part and uncharged part ≥100MΩ
电器强度:
带电部分与外壳间施加1500VAC电压,漏电流0.5mA历时1分钟,无穿击现象
Strength of appliance:
     Apply 1500VAC voltage between the live part and shell with leaking current of 5mA for 1minute,it has no breakdown.


工作原理:

     双控的上面有二个电器开关,有1、2、3三个端子,1、3为常闭,1、2为常开。当器皿中的水位上升,导致浮子上浮,这时1、3断开,1、2闭合。当器皿中的水位下降到标准水位时,1、3又为常闭,1、2又为常开。电器又恢复正常。
Work principle:
    There is two switches and terminal 1,2,3 above the double controller.Of it,terminal 1 and 3 are often closed and terminal 1 and 2 are often opened.When the water level in the vessel rises,the floater will float upward,so terminal 1 and 3 are opened and terminal 1 and 2 are closed.When the water level drops under the standard water level,terminal 1 and 3 are closed and terminal 1 and 2 are opened and the electrical appliance can work normally.
