Description

Power saving safety rapid charger

The utility model technical field belongs to the power converter apparatus that the AC power input is transformed to direct current power output, particularly a kind of energy-saving safety quick charger.

At present, the AC power power converter apparatus that is transformed to direct current power output is everlasting and is used the transformer step-down before the rectification circuit.The internal resistance of reducing transformer own will consume more energy, as adopt transformer---the charger that the rectifier mode is made, its shortcoming is that the transformer power consumption is bigger, when being used for battery charge, along with battery power increases, charging rate slows down greatly, and need often to adjust transformer, and output voltage is constantly increased, this has all increased operator's trouble greatly, charging rate is not high, and the charging interval is long.

The purpose of this utility model provides a kind of quick charger with the electronic component step-down.

This charger is realized with the following methods: it is made of rectification circuit RC step-down current stabilization circuit and switch.On the lead that connects power supply and rectification circuit, be serially connected with RC step-down current stabilization circuit and K switch.RC step-down current stabilization circuit and K switch on the lead have a group or more.Electricity in parallel is connected to A.C. contactor CJ before the RC of phase line circuit, its contact CJ ₁And CJ ₂Be connected on respectively on phase line and the zero line.

This charger adopts RC step-down current stabilization circuit, saves typical transformer, so consumed energy not basically itself, the current stabilization of saves energy, and step-down greatly is reliable, and is safe in utilization, applied widely, and the charging interval lacks, and is cheap.

Fig. 1 portable energy-saving is the charger electrical schematic diagram safely and fast.

The fixed energy-saving safety quick charger of Fig. 2 electrical schematic diagram.

Below in conjunction with accompanying drawing this charger is described in further detail:

Portable energy-saving charger (see figure 1) safely and fast is serially connected with RC step-down current stabilization circuit on the lead between 220 volts of power supplys and the bridge rectifier D, be serially connected with one group of RC circuit on the lead wherein, be serially connected with three groups of RC circuit on another root lead, every group of circuit has a K switch to be used to control the disconnected or logical of this group circuit respectively.In order to show voltmeter, indicator light and ammeter need be installed.Through output DC behind the step-down rectifier.Because the RC circuit is selected the parameter difference, causes output DC voltage that three numerical value are arranged, and selects arbitrary value or special requirement dc voltage value in 6 volts, 12 volts, 24 volts or 36 volts for use according to customer requirements.Because of not adopting transformer, it can cause volume little, the charger of a plurality of direct currents outputs is arranged, thereby cost is also low, and saves energy greatly, and power consumption was zero when this machine was unloaded.Applied widely, during charging, the charging current constant current, electric current is constant substantially, and the storage battery of different voltages is at corresponding current gear serial connection charge arbitrarily.Owing to connect the zero line of power supply and phase line by RC step-down current stabilization circuit, use is safe especially.Needn't divide phase line, zero line during charging, can arbitrarily attaching plug be inserted 220 volts of AC power, adopt single group RC circuit because of not distinguishing the deadly defect that Live line Zero line causes personal injury thereby overcome.Resistance system in the RC circuit shields, and prevents the energized heavy current impact of moment, can rapidly the charge discharging resisting that stores in the capacitor be come out when charging finishes again, in order to avoid damage parts and avoid depositing the accident that electricity is hurted sb.'s feelings.

Fixed its electrical schematic diagram of energy-saving safety quick charger (see figure 2) is to be serially connected with three groups of RC circuit on the phase line of energized (220 volts of AC power) and bridge rectifier, every group of RC circuit has a K switch, and electricity in parallel is connected to A.C. contactor CJ before the RC circuit.The docking point CJ of A.C. contactor CJ ₁And CJ ₂Be serially connected in respectively on phase line and the zero line.Remove contact CJ on the zero line ₂Directly connect bridge rectifier outward.A.C. contactor CJ shields, when plug inserts AC power, if phase line connect, charger work, if the phase line of plug is joined with the zero line of power supply, that is the zero line of plug is connected with the power supply phase line, then because CJ ₂Disconnect, circuit disconnects, and charger is work not.These facility have described all advantages of portable energy-saving quick charger.Owing to select the component parameters difference for use, volume is bigger, and charging current is also bigger, is specially adapted to the full-sized car storage battery is charged.

Above-mentioned two kinds of chargers can fill dry cell 1～100 joint, or 1～15 of 1～15 in small-sized storage battery or automobile storage battery.Than charger, shorten about 2 hours of dry battery charge time, about 6～7 hours of medium and small storage battery charging interval, about 7～12 hours of automobile storage battery charging interval greatly during the charging of this machine with the transformer step-down.Charging current often selects for use 0.4 peace, 1.8 peaces and 6 to pacify several grades.

This energy-conservation charger safely and fast is used for various dry cells (comprising manganese-zinc battery, nickel-cadmium cell, alkaline battery) and various storage battery (comprising various small batteries and full-sized car storage battery) are carried out constant current charge.
