沥青摊铺机电加热熨平板的预热,均采用摊铺机自身配装的交流发电机获取380V交流电,通过加热棒对熨平板进行加热,从而使熨平板获得必要的预热温度。配装电加热熨平板的沥青摊铺机虽都配备必要的断路器、空气开关或漏电保护装置,但这些都属于被动保护,无法主动预防或提前检测到电加热系统可能存在的安全隐患。为了确保摊铺机操作人员安全,防止电器部件损坏,我们专门设计了一种用于测量地线与零线之间绝缘状况的检测模块,可以在绝缘等级不够时进行报警提示。
Asphalt Paver Electric heating The preheating of the screed takes 380 V AC from the alternator equipped with the paver itself and heats the screed with the heating rod so that the screed gets the necessary preheat temperature. Although asphalt paver equipped with electric heating screed is equipped with the necessary circuit breakers, air switches or leakage protection devices, these are passive protection and can not take the initiative to prevent or detect in advance the potential safety hazard of the electric heating system. In order to ensure the safety of the paver operator and prevent the electrical components from being damaged, we have specially designed a detection module for measuring the insulation between the ground and the neutral line, which can give an alarm when the insulation level is not enough.
