Abstract:
一馬達啓動器(4)包含一接觸器(6)以及一過載繼電器(8)。該過載繼電器包含一具有一電壓(12;64)之電源供應器(10)、一由該電源供應器之電壓供電並被構建成控制該接觸器之處理器(14)、以及一過電壓電路(16;50)。該過電壓電路包含一具有一電壓(54)之電壓參考(52)、一比較器(56)、一負載(60)、以及一開關(58)。該比較器包含一用以輸入該電源供應器電壓之第一輸入(62)、一用以輸入該電壓參考之電壓之第二輸入(65)、以及一輸出(66),該第一輸入與該電壓參考之該電壓協同運作以決定一臨界電壓。該開關受比較器輸出之控制且被構建成在該電源供應器電壓超過該臨界電壓之時將該電源供應器電壓透過該負載電性連接至接地端(68)。
Abstract(Chinese):

一马达启动器(4)包含一接触器(6)以及一重载继电器(8)。该重载继电器包含一具有一电压(12;64)之电源供应器(10)、一由该电源供应器之电压供电并被构建成控制该接触器之处理器(14)、以及一过电压电路(16;50)。该过电压电路包含一具有一电压(54)之电压参考(52)、一比较器(56)、一负载(60)、以及一开关(58)。该比较器包含一用以输入该电源供应器电压之第一输入(62)、一用以输入该电压参考之电压之第二输入(65)、以及一输出(66),该第一输入与该电压参考之该电压协同运作以决定一临界电压。该开关受比较器输出之控制且被构建成在该电源供应器电压超过该临界电压之时将该电源供应器电压透过该负载电性连接至接地端(68)。

Abstract(English):

A motor starter (4) includes a contactor (6) and an overload relay (8). The overload relay includes a power supply (10) having a voltage (12; 64), a processor (14) powered by the power supply voltage and being structured to control the contactor, and an overvoltage circuit (16; 50). The overvoltage circuit includes a voltage reference (52) having a voltage (54), a comparator (56), a load (60) and a switch (58). The comparator includes a first input (62) for the power supply voltage, the first input cooperating with the voltage of the voltage reference to determine a threshold voltage, a second input (65) for voltage reference voltage, and an output (60). The switch is controlled by the comparator output and is structured to electrically connect the power supply voltage to ground (68) through the load whenever the power supply voltage exceeds the threshold voltage.
