评估电磁接触器的温度的方法及实现该方法的接触器
摘要：
本发明涉及一种评估接触器的温度的方法，该接触器包含设计成作用在施加于致动线圈的电压的控制部件（20）上的处理单元（2）。测量部件（24）测量流入所述至少一个致动线圈（3）中的电流（I）。所述方法在于：发送在于将电压施加于致动线圈（3）的端子（L1、L2）使流入线圈中的电流（I）能够被修改成第一参考值（I1）的闭合命令；发送在于固定致动线圈（3）的端子（L1、L2）上的称为开断电压的电压的开断命令；测量流入所述致动线圈（3）中的电流（I）；在电流（I）的信号上进行特定值的获取；以及分析特定值以评估致动线圈（3）的工作温度。
摘要（英）：

The invention relates to a method for evaluating the temperature of a contactor. The contactor comprises a processing unit (2) designed to act on a control component (20) of the voltage applied to an actuating coil. A measuring component (24) measures an electric current (I) flowing in at least one actuating coil (3). The method lies in the following steps: a closing order of applying voltage to the terminals (L1, L2) of the actuating coil (3)and enabling the electric current (I) flowing in the coil to be modified up to a first reference value (11) is sent, a drop-out order of fixing a voltage called drop-out voltage at the terminals (L1, L2) of the actuating coil (3) is sent, the electric current (I) flowing in the actuating coil (3) is measured, specific values on a signal of the electric current (I) are acquired, and the specific values for evaluation of the operating temperature of the actuating coil (3) are analyzed.
