Abstract
The utility model relates to a safety charger. A pair of normally open contacts of a control button (3) and a pair of normally open contacts of a relay (7) are connected in parallel between the common end of a fuse (1) and an electric source indicator (2) and the input end of a transformer (4). The output positive end of a rectification bridge (6) is connected with the positive end of a voltmeter (9) through the other pair of normally open contacts of the relay (7). Two ends of the voltmeter (9) are connected with alarm circuits in parallel, a first end of each of two groups of coils of the relay (7) is connected with a negative output end of the rectification bridge (6), and a third pair of contacts which are additionally arranged by a serial converting switch (5) of a group of coils is connected the second end of two groups of coils. The second end of two groups of coils is connected with the positive output end of the rectification bridge (6) through another pair of normally open contacts of the control button (3), and a diode (8) and a linked switch (14) of a positive charging clip (15) are connected between the second end of two groups of coils and the positive charging clip (15) in series. The safety charger has the advantage of protecting the charger and the storage battery.
Description
Technical field
The utility model relates to a kind of charger, particularly a kind of charger with defencive function.
Background technology
The two voltage charging facility of transformer transformation bridge rectifier commonly used at present have advantage simple in structure and easy to use; but it does not have defencive function under misoperation and fortuitous event; through the be damaged phenomenon of charger and storage battery of regular meeting; charger both positive and negative polarity two charging folders can damage charger and storage battery with the positive and negative poles of battery wrong during such as charging; charger connect power supply and when not charging the unexpected short circuit of two charging folders can damage charger; misusing charger high voltage shelves is that the charging of low-voltage storage battery can damage charger and storage battery, and charger two charging folders can not damage charger and storage battery with the positive and negative poles of battery wrong when charger connect power supply.
Summary of the invention
The purpose of this utility model provides a kind of charger with protection charger and storage battery function.
Technical solution of the present utility model is: it is to improve to form on the basis of the two voltage charging machines of existing transformer transformation bridge rectifier, between fuse and power supply indicator common port and transformer input and be connected to a pair of normally opened contact of control button and a pair of normally opened contact of relay, rectifier bridge output plus terminal and voltmeter anode are connected to normally opened contact by another of relay, at the voltmeter two ends and be connected to warning circuit, warning circuit is by buzzer siren, alarm lamp and diode are composed in series, two groups of coil first ends of relay are connected with rectifier bridge output negative terminal, the 3rd pair of contact that one group of coil second end serial connection change over switch is set up is connected with two groups of coil second ends, two groups of coil the two or two ends and rectifier bridge output plus terminal are connected to normally opened contact by another of control button, be serially connected with diode and anodal charging folder linked switch between two groups of coil second ends and the anodal charging folder, be connected with ammeter between rectifier bridge output negative terminal and the negative pole charging folder.
Technique effect of the present utility model is: it has the advantage of protection charger and storage battery.
