皮带输送系统运行电机故障报警装置
摘要：
本实用新型的目的是设计一种皮带输送系统运行电机故障报警装置，它是由电机、继电器I、继电器II、红灯、绿灯、警铃、保险丝、开关I、开关II组成，开启开关I、开关II后，电流接通，继电器I中的电磁铁I通电把弹簧片I吸在触点Ia，电机运行，同时继电器II中的电磁铁II通电把弹簧片II吸在触点IIa，绿灯亮；当电机出现故障、保险丝熔断或开关I断电，继电器I中的电磁铁I断电，弹簧片I与触点Ia断开并回归到触点Ib，继电器II中的电磁铁II同时断电，弹簧片II与触点IIa断开并回归到触点IIb，此时警铃鸣响，红灯亮，便于操作人员及时发现和检修。
摘要（英）：

The utility model aims to design a belt conveyor system operation motor fault alarm device, it is by the motor, relay I, relay II, the red light, the green light, the alarm bell, the fuse, switch I, switch II constitutes, open switch I, behind the switch II, the electric current switch -on, electro -magnet I circular telegram among the relay I is inhaled spring leaf I at contact ia, the motor operation, electro -magnet II circular telegram among the relay II is simultaneously inhaled spring leaf II at contact IIa, the green light is bright, when the motor break down, the outage of fusing of metal or switch I, electro -magnet I outage among the relay I, spring leaf I returns contact ib with contact ia disconnection, the electro -magnet II among the relay II cuts off the power supply simultaneously, spring leaf II returns contact IIb with contact IIa disconnection, the alarm bell was rung this moment, the red light is bright, the operating personnel discovery in time and overhauing be convenient for.
