Description
The utility model relates to the sealed lead acid storage battery technical field, particularly a kind of equipment of sealed lead acid storage battery being repaired charging.
Sealed lead acid storage battery is to develop novel lead-acid storage battery faster at present, between the whole normal operating period, need not moisturizing, mend acid, under the correct behaviour in service, its cycle charge-discharge surpasses more than 300 times, can reach useful life more than 3 years, self-discharge rate is extremely low, less than 1%, is widely used in communication, traffic, electric power, finance, computer network, emergency lighting system, the Moped Scooter energy etc.But sealed lead acid storage battery deposit or use in, have self discharge or use discharge, when the 12V battery is discharged into 10.5V/1CA or 10V/1CA, must in time charge, otherwise will cause overdischarge and damage storage battery storage battery.In addition, place or floating charge work not charge or discharge of regular period as static state, storage battery may can not fill electricity more greatly because of internal resistance to be damaged and scraps, and mishandlingly also can pollute environment.
Because of sealed lead acid storage battery generally adopts lead-calcium alloy slab lattice, in deep discharge or long-term floating charge not in the discharge process, sulfation takes place in its grid interface that contacts with active material, at the very big resistance of interface generation, be that accumulator internal resistance increases, at this moment common charger can fill.At present, to because of the sealed lead acid storage battery of placing or the floating charge overlong time is damaged, have only and do to scrap processing.Phase in " electronics newspaper " 23 days the 25th June in 1996 3 editions " talking the restorative procedure of used and scrapped battery " is introduced the circuit of using as shown in Figure 1 and carries out high-voltage charge, exist weak point: first, storage battery and 220V alternating current link by the direct step-down of electric capacity, and it is dangerous to charge; The second, can only the storage battery of a constant volume be charged, no additives for overcharge protection, charging current is little, the charging interval is oversize, as the 6V3AH charge in batteries time be 30～35 hours.Bad as charging current control, will cause quick-fried sound, cause the internal storage battery open circuit and thoroughly damage.
At the deficiency that above-mentioned prior art exists, the utility model proposes a kind of sealed lead acid storage battery and repair charger, can be to because of placing or the floating charge overlong time has been damaged the storage battery that can't use and repaired and charge.
The utility model reaches by following technical measures: one connects the transformer B of 220V civil power, is characterised in that:
1. in two rectifier charging circuit, reverse protection diode D12 and current-limiting protection resistance R 11 of connecting and being linked in sequence and forming between winding and the storage battery E of B level of transformer, press charge circuit in the formation by D11, C11;
2. additives for overcharge protection circuit and the reverse protection diode D33 that the rectifier charging circuit, transistor T, R31, the D32 that are made up of D31, C31 form that be linked in sequence between transformer B secondary winding and storage battery E constitutes the low pressure charge circuit;
3. voltage stabilizing didoe D21 and capacitor C 21 formation momentary pulse discharge loops have been linked in sequence between two series connection windings of transformer B time level and the storage battery E.
Described resistance R 11 two ends are parallel with the middle pressure charging current limiter protection indicating circuit of R12 and D13 composition.The c of transistor T, e level two ends are parallel with the low pressure winding charging indication of R32 and D34 composition.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is that " electronics newspaper " introduced with high voltage by the direct step-down charging of electric capacity schematic diagram.
Fig. 2 is a circuit theory schematic diagram of the present utility model.
Fig. 3 is an external form diagram of the present utility model.
As shown in Figure 2: the 220V electric main enters the elementary winding of transformer B, in secondary winding output Ua, Ub, two groups of alternating voltages of low pressure.When the positive half cycle of alternating current, press Ua among 28～36V of two series connection of B level of transformer winding terminal, with the rectifier charging circuit that D11, C11 constitute, D12 reverse protection, R11 current-limiting protection, storage battery E presses charge circuit in constituting; 17～20V low pressure Ub of transformer B secondary winding end, the rectifier charging circuit, transistor T, R31, the D32 that form with D31, C31 form additives for overcharge protection circuit, D33 reverse protection and storage battery E formation low pressure charge circuit.When the alternating current negative half period, press Ua among 28～36V of two series connection of B level of transformer winding terminal, constitute storage battery with voltage stabilizing didoe D21, capacitor C 21 and storage battery and carry out the momentary pulse discharge loop at the alternating current negative half period.The charging initial stage, because accumulator internal resistance to be repaired is bigger, mainly by the special current limiting device current limliting of R11 storage battery is carried out current-limiting charge by D11, C11 rectification charging output pulsing medium direct voltage at the positive half cycle of alternating current by middle pressure Ua, at this moment the storage battery two ends have the voltage charging of 15-60v approximately, R11 is a semistor, pressing the charging current of Ua in the major control is 40-180mA, and R12, D13 are the work indications after R11 plays current-limiting protection; At the alternating current negative half period, when | Ua|＞U
D21-U
EThe time; voltage stabilizing didoe D21 reverse breakdown; by C21 storage battery is carried out the momentary pulse discharge; can accelerate to eliminate the sulfation of battery grid like this; accumulator internal resistance is reduced rapidly; reach reparation to storage battery; general process can make the storage batteries both end voltage return to about 14V in 1-5 hour; this moment, low pressure Ub passed through D31; the C31 rectification charging is through transistor T; D33 begins to charge a battery; and continue storage battery is repaired; until returning to 12V left and right sides voltage; at this moment charging current can reach about 0.5-1A; mainly charge normal by low pressure Ub; transistor T; R31; D32 forms the overvoltage charge protection; when the storage battery both end voltage is charged to the 13.8V left and right sides; the conducting of D32 reverse breakdown; transistor T ends; have only 40mA left and right sides protective current and R32 by R11; the electric current that D34 forms low pressure winding charging indication carries out trickle charge; prevent the charging of storage battery overvoltage, D12; D33 is respectively to C11 and transistor T between the alternating current negative half-cycle; D32; C31 shields.In entire work process, at the alternating current negative half period | Ua|＞U
