一种多功能用电保护器
摘要：
本实用新型公开了一种多功能用电保护器，包括喇叭B、电阻R3、单向晶闸管Q1和二极管D3，所述电阻R3的一端连接二极管D4的阳极和电源VCC，电阻R3的另一端连接三极管V1的基极，三极管V1的发射极连接喇叭B，喇叭B的另一端连接二极管D4的阴极、电容C3、二极管D1的阳极、电容C2和负载H，二极管D1的阴极连接电阻R1。本实用新型多功能用电保护器结构简单、元器件少，利用电容充放电原理结合稳压二极管和单向晶闸管实现了对负载的软启动控制，同时电路还具有停电报警的功能，因此具有使用寿命长、功能多样和成本低的优点。
摘要（英）：

The utility model discloses a multi -functional power consumption protector, including loudspeaker B, resistance R3, unidirectional thyristor Q1 and diode D3, diode D4's positive pole and power VCC are connected to resistance R3's one end, and triode V1's base is connected to resistance R3's the other end, triode V1's projecting pole connected loudspeaker B, loudspeaker B's other end connection diode D4's negative pole, electric capacity C3, diode D1's positive pole, electric capacity C2 and load H, diode D1's negative pole connecting resistance R1. The utility model discloses multi -functional power consumption protector simple structure, components and parts are few, utilize the charge and discharge of capacitor principle to combine zener diode and unidirectional thyristor to realize a soft start control to the load, and the circuit still has the function that has a power failure and report to the police simultaneously, therefore has long service life, function advantage various and with low costs.
