Abstract
A power off protector belongs to an electrical switch, and mainly solves the problem of the impact and damage to electric equipment after sudden power off and instantaneous power supply recovery. The power off protector comprises an electromagnetic relay, a capacitor, a diode, electric equipment, a movable switch, a push-button switch, an insulator and an armature, wherein the electromagnetic relay and the armature are serially connected into a circuit, the insulator and the electric equipment are serially connected into the circuit, and the capacitor and the diode are in parallel connection. The power off protector can effectively prevent and avoid the impact and damage to the electric equipment after sudden power off and instantaneous power supply recovery, has a safety protection function, and can reduce electric energy waste.
Description
Technical field
The utility model relates to a kind of electric switch, specifically a kind of power-off protector.
Background technology
Variation day by day along with present household electrical appliance, the use of various electrical equipment all be unable to do without power supply, but when unexpected experience is cut off the power supply and is restored electricity, electrical equipment is easily because of frequent switch and transient voltage is very high when switching on makes inner component aging influence the life-span, even directly burn out components and parts, especially the harm for refrigerator, television set and computer is bigger, causes very big loss can for people's property.
The utility model content
The purpose of this utility model is to provide a kind of power-off protector, and this protector has after the equipment sudden power and the function of conducting voluntarily when restoring electricity.
The technical scheme in the invention for solving the technical problem is: a kind of power-off protector; it is characterized in that; comprise electromagnetic relay, capacitor, diode, power consumption equipment, removable switch, push-button switch, insulator and armature; electromagnetic relay and armature, insulator and power consumption equipment are connected in the circuit, and capacitor, diode adopt in parallel.
The beneficial effects of the utility model are: when accident power-off, can cut off circuit; When the service restoration, circuit remains disconnection.Can effectively prevent and avoid power consumption equipment impact and damage to equipment when meeting with outage back and instantaneous recovery power supply suddenly, have the function of safeguard protection and reduce waste of energy.
Description of drawings
Fig. 1 is an electrical principle schematic diagram of the present utility model.
Among the figure: 1 electromagnetic relay, 2 capacitors, 3 diodes, 4 power consumption equipments, 5 removable switches, 6 push-button switches, 7 insulators, 8 armature.
Embodiment
As shown in Figure 1: a kind of power-off protector; comprise electromagnetic relay 1, capacitor 2, diode 3, power consumption equipment 4, removable switch 5, push-button switch 6, insulator 7 and armature 8; electromagnetic relay 1 is connected in the circuit with armature 8, insulator 7 and power consumption equipment 4, and capacitor 2, diode 3 adopt in parallel.
During use, power-off protector is connected between power consumption equipment 4 and the supply line, when circuit is connected, power consumption equipment work, capacitor 2 chargings; When accident power-off, the forward conduction function of diode 3 makes capacitor 2 discharges and electromagnetic relay 1 constitute the loop, electromagnetic relay 1 work, inhale lower armature 8, insulator 7 inserts between the last downlink sheet of switches, this moment removable switch 5 with block foremost, after capacitor 2 discharges and finishes, still remain on original position, cut off circuit; When service restoration, circuit remains disconnection, and press switch this moment, and removable switch is moved by former track, and armature 8 drives insulators 7 and ejects switch closure, circuit turn-on.
