Abstract

The invention relates to an automatic input device of an emergency power supply. A commercial power 220 power supply is used as a main power supply for working, and a storage battery is selected and used as the emergency power supply. The main power supply is controlled by a normally open contact of a relay IC1; and the emergency power supply is controlled by a normally closed contact of the relay. When the commercial power is normal, the relay IC1 is closed, and the normally open contact of IC1 is connected to the working power supply of a load; when the commercial power is suddenly stopped, the relay IC1 is tripped off, and the normally open contact of IC1 disconnects the working supply for supplying the load; and meanwhile, the normally closed contact of IC1 is also connected to the emergency power supply consisting of the storage battery, so that the emergency power supply supplies the working power supply of the load in seconds.

Description

A kind of automatic throw-in equipment of stand-by power supply

Technical field

The present invention relates to a kind of automatic throw-in equipment of stand-by power supply.

Background technology

The commercial supermarket in cities and towns, in the time doing business evening, often can encounter and have paroxysmal power outage at present,Shop assistant will start the illumination in the emergent market of stand-by generator at once, to facilitate the normal business in supermarket. Although superGenerally there is standby power supply apparatus in city, still exists the regular hour poor, no but generating equipment will be generated electricity outCan supplement timely the urgently needed power supply in market.

Summary of the invention

The automatic throw-in equipment of a kind of stand-by power supply of the present invention, disclosing a kind of battery is second source, utilizes pureSinewave inverter function, utilizes the operating mechanism function of relay, while business at night in supermarket just in case encounterSuddenly power outage, can, automatically by in-put of spare power supply within the time difference of level second, shorten the time having a power failure, and protectsThe business in card supermarket is normally carried out.

An automatic throw-in equipment for stand-by power supply, its electric circuit constitute by battery, anti-overcharge circuit,, anti-Reverse charge circuit, batteries, in-put of spare power supply function circuit, anti-overdischarge circuit, pure sine wave inversionCircuit, alternating current 220V control relay circuit and load circuit composition.

Brief description of the drawings

Accompanying drawing is a kind of circuit theory diagrams of automatic throw-in equipment of stand-by power supply.

Detailed description of the invention

As shown in drawings, IC1 is relay, the relay that model is alternating current 220V, and capacity is according to load meritRate determines. L is the phase line of alternating current, and N is the zero line of alternating current. K controls chopper switch, when it is closed,Relay IC1 work, its normally opened contact IC1 adhesive, connects the working power of load.

As shown in drawings, IC2 is battery charger, can be single-phase bridge rectification equipment, can be also tooSun energy charging equipment, capacity is determined by bearing power. D2, R1, D3 form anti-overcharge circuit, work as electric power storageWhen pond is fully charged, its terminal voltage adds that the pressure drop voltage of D1 reaches the two ends electricity that D2, R1, D2 are in seriesPress, now both-end voltage-stabiliser tube D2 conducting, D3 is luminous, represent that battery has been full of electricity, and battery stops fillingElectricity. D1 is anti-reverse charging diode, plays anti-reverse charging electro ultrafiltration in circuit. E is batteries, capacityDetermine according to bearing power.

As shown in drawings, R2, R3, R4, A1, A2, D4, J1, T composition in-put of spare power supply operation electricityRoad. Wherein A1 is the starting button of in-put of spare power supply, and in the time that A1 presses, the base stage of triode T obtains partiallyPut and conducting, relay J 1 adhesive, its normally opened contact J1 closure, connects battery and IC3 and R3, R4Circuit. Connect R3, R4 circuit, get the branch pressure voltage of its R3, R4, its effect is to unclamp as button A1After, still there is power drives triode T to keep conducting; A2 button is the action button of stopping sending stand-by power supply,In the time that A2 presses, the base stage of triode T is pulled to zero potential and triode T is ended by A2, relay J 1Tripping, its normally opened contact J1 cut-out battery is sent to the circuit of IC3, stops storage battery power supply. D4 is relayThe fly-wheel diode of device, it protective relay.

As shown in drawings, IC3 is pure sine wave inverter, and capacity is determined by bearing power. IC4 is load,The phase line L of load is by Control, and normally opened contact J1 controls the civil power 220V AC power that is sent to load;Normally-closed contact J1 controls the pure sine wave inversion 220V power supply that is sent to load. Its control procedure is: negative at ordinary timesCarry by civil power 220V power supply supply load, and by in-put of spare power supply at stand-by state, now stand-by power supplyDisconnect being connected of stand-by power supply and load by the normally-closed contact of relay, single by civil power supply load work electricitySource. When civil power stop suddenly for time, 220V AC relay loses driving power and tripping is often opened electric shock J1 and cutThe broken path of civil power and load, meanwhile, in the moment disconnecting at the normally opened contact J1 of relay J 1, it is normally closedContact J1 also moment closure, connect load power source, now load is worked by pure sine wave inverter supply loadPower supply. After civil power disappears, while recovering power transmission again, the IC1 relay in circuit obtains electric adhesive, drives and often opensContact J1 closure; Meanwhile, its normally-closed contact J1 tripping, cuts off pure sine wave inverter output circuit,Load list is supplied with working power by civil power.

Claims

1. an automatic throw-in equipment for stand-by power supply, its main power source is made up of city's alternating current 220V power supply, and standbyFormed by batteries with power supply; Described main power source is by the normally opened contact control of alternating current 220V relay IC1,Stand-by power supply is controlled by the normally closed electric shock IC1 of same AC relay; At ordinary times by the manipulator of stand-by power supplyStructure is by in-put of spare power supply at state for subsequent use, and like this, in the time that civil power suddenly disappears, load is given in its controlWorking power tripping because AC relay IC1 loses driving power, it is often opened electric shock IC1 and has cut off main electricityResource loop; Meanwhile, stand-by power supply also within the time difference of level second by the normally-closed contact IC1 of same relayConnect the working power of load, worked by stand-by power supply supply load, the working properly of proof load carries out.
