Abstract
The utility model discloses a micro-poleless wide voltage lead-acid accumulator protector. The protector solves the problems that the vitriol-lead crystal is easy to appear when improperly using the lead-acid accumulator at present and thus the service life of accumulators is shortened. The accumulator protector has advantages of a simple structure, convenient using, and can effectively avoid vitriol-lead crystal appearing and prolong the service life of the lead-acid accumulator. The structure of the accumulator protector is that the protector is connected with the lead-acid accumulator through a plug; the protector comprises a rectification circuit which is connected with the lead-acid accumulator through a plug, the output end of the rectification circuit is connected with the output end of a multivibrator, the output end of the multivibrator is feedback to the output end of the lead-acid accumulator.
Description
Technical field
The utility model relates to a kind of battery protecting apparatus, especially designs a kind of miniature nonpolarity wide voltage lead-acid accumulator protecting device.
Background technology
Usually lead acid accumulator forms lead sulfate when discharge, easier is reduced to lead during charging.If the operation and maintenance of battery is not good at, for example frequent undercharge or over-discharge can will form a kind of thick hard lead sulfate crystallization, the stressed variation of charging during charging gradually on battery cathode.This phenomenon is called as irreversible sulfation, and it causes that battery capacity descends, even becomes the reason that the life of storage battery stops.
Summary of the invention
The purpose of this utility model is exactly to be prone to the lead sulfate crystallization when being not good in order to solve present lead acid accumulator use; cause problems such as shorter battery life; provide a kind of have simple in structure; easy to use; can effectively avoid the lead sulfate crystallization to generate, effectively prolong the miniature nonpolarity wide voltage lead-acid accumulator protecting device of advantages such as lead acid accumulator useful life.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of miniature nonpolarity wide voltage lead-acid accumulator protecting device; it is connected with lead acid accumulator by plug; described protector comprises rectification circuit; it is connected with lead acid accumulator by plug; the input of the output termination multivibrator of rectification circuit, the output of multivibrator feeds back to the output of lead acid accumulator.
Described rectification circuit is a full bridge rectifier.
Described multivibrator is made up of at least two triodes, and its output is connected with the output of lead acid accumulator through electric capacity.
Described multivibrator is made up of four triodes.
Described triode model is KTC9014.
This protector attaching plug is inserted battery feed plug (voltage is 24v-48v); this protector promptly produces the high frequency rectangle square-wave voltage that changes with input supply voltage; make thick hard lead sulfate crystallization softening, become reversible lead sulfate, make charge acceptance recover normal.This protector is inserted in the new battery circuit, can stop thick hard lead sulfate crystallization to generate.1-3 times of the useful life of prolongation storage battery.This protector is inserted the used batteries circuit, can make battery recover normally (about 7-30 days) gradually.
The beneficial effects of the utility model are: simple in structure, easy to use, can effectively solve the lead sulfate crystallisation problems, and prolong the useful life of lead acid accumulator.
Description of drawings
Fig. 1 is an electrical diagram of the present utility model;
Fig. 2 is an electrical schematic diagram of the present utility model.
Wherein, 1. rectification circuit, 2. multivibrator, 3. lead acid accumulator.
Embodiment
Among Fig. 1,2; protector is connected with lead acid accumulator 3 through power supply adapter; the both positive and negative polarity of lead acid accumulator is through plug input full bridge rectifier 1; after full-bridge rectification, be divided into positive-negative power and supply with nonpolarity, the wide voltage source of multivibrator 2 formation; multivibrator 2 produces the high frequency rectangle square-wave voltage that changes with input voltage; duty ratio is 50% the positive negative pulse stuffing positive/negative plate by positive-negative power line input lead acid accumulator 3, eliminates the big crystallization of lead sulfate.This protector appliance is few, and it is little to take up room, in light weight, in 3.5*5.5 centimetre the capsule of all components and parts can being packed into, but and plug and play, the worry of having removed wiring from.
