The device comprises a self-coupling voltage transformation circuit, a voltage stabilization control circuit, a protection control circuit and a time delay control circuit, wherein the self-coupling voltage transformation circuit, the voltage stabilization control circuit, the protection control circuit and the time delay control circuit are composed of a resistor, a capacitor, a transistor, a rectifier diode, a voltage stabilizing diode, a light emitting diode, a piezoelectric ceramic buzzer, a piezoresistor, an interrupter, a single crystal tube and the like. The whole machine has simple circuit and convenient installation and debugging. High working reliability and low cost, and is an ideal electric appliance protection device for families and service industries such as refrigerators, televisions, fans and the like.
Description
The utility model is a kind of full-automatic voltage regulating multifunctional protector that is used for household electrical appliance protections such as television set, refrigerator, electric fan, and it belongs to the daily life electric product.
Before the utility model, protector for household electrical appliances such as television set, refrigerator have three kinds of patterns: first kind is the voltage-regulation type protector, is to belong to positive type protector, and range of regulation is between 180V-240V.Less than 180V and greater than 240V the time, this protector has just lost the function of pressure regulation; Second kind is the amorphous type protector, when voltage during less than 180V or greater than 240V, can cut off appliances power source automatically; The third belongs to the simple type protector, and it can only solve the problem of sudden power or telegram in reply, and can not solve the problem of voltage ripple of power network, and above three kinds of protectors all can not solve the problem that domestic electric appliance is shielded because of effects of lightning.
The purpose of this utility model is to provide a kind of novel full-automatic voltage regulating multifunctional protector, this full-automatic voltage regulating multifunctional protector to people.When line voltage fluctuates between 165V-245V, can be between 195V-215V with voltage automatic stabilisation; When line voltage, can be cut off the electricity supply during greater than 250V automatically less than 160V, sound and light alarm simultaneously; When running into unexpected power failure, instantaneous when sending a telegram in reply again, it can be cut off the electricity supply and delay time automatically; When lightning induced voltage surpasses 250V, protection component work, the effect of protection household electrical appliance has been played in fuse RD fusing.Designed the television set socket CZ that voltage stabilizing output is arranged in addition
1Change individual elements and can also play the effect of protecting other electric equipment.
Below in conjunction with accompanying drawing the utility model is done more detailed explanation.
