Abstract

The utility model discloses an open circuit trouble shooter for a storage battery, and relates to a detection device for storage batteries and storage battery sets in an open circuit indication status. The trouble shooter mainly solves the problems that when open circuit failure occurs in the storage battery, a user can only judge through the appearance with the help of a self-provided flashlight,which is time-consuming and labor-consuming and can not eliminate the troubles quickly. The trouble shooter is characterize din that a crystal diode, an LED and a resistor are connected in series; the positive pole is connected with a positive pole testing contact terminal through a reposition inspection button and the negative pole is connected with a negative pole testing contact terminal for detecting the storage battery normal work circuit. The other crystal diode, the other LED, and the other resistor are connected in series; the negative pole is connected with a positive pole testing contact terminal through a reset button; and the positive pole is connected with a negative pole testing contact terminal to detect the storage battery open circuit state. The trouble shooter can automatically, accurately, and visually detect and indicate the fail storage battery, and the operation is convenient and quick, thereby quickly performing trouble shooting and avoiding traffic accidents caused by open circuit of the storage battery.

Description

Accumulator open circuit fault detecting device

Technical field

The utility model relates to accumulator and the battery pack pick-up unit in the off state indication, relates to specifically being applicable to rail vehicles, the used accumulator open circuit fault of vehicles detecting devices such as automobile, motorcycle, electric bicycle.

Background technology

When accumulator and battery pack open circuit fault occurs in utilization, generally be to detect measurement with multimeter by the professional, need certain electrician's knowledge and professional skill, generally require special training and study, at present, also do not use multimeter relevant apparatus in addition directly to judge the device of indication accumulator open circuit fault; For some special industry such as railway locomotive, accumulator generation open circuit fault in the operation way, owing to there is not good judgment processing method, locomotive steward is for many years puzzling always, this type of fault steward is taken place owing to lack necessary instrument, generally only can declare, waste time and energy, and be difficult to fix a breakdown rapidly with outward appearance with providing pocket lamp bulb for oneself, because locomotive loses power supply, the radio train dispatching telephone of the lighting circuit of locomotive and safety feature, automatic signal all can not normally be used, and therefore, will cause serious consequence, traffic safety is constituted greatly threat, if judgment processing is untimely, will directly cause train running delay even accident of locomotive defect.Use battery industry at other, only judge accumulator failure, and can not show the accumulator open circuit fault automatically with indicating.

Summary of the invention

The purpose of this utility model is at above-mentioned deficiency, and the accumulator failure detecting device a kind of automatic accurate, directly perceived, convenient to operation that provides.

Technical solution of the present utility model is: accumulator open circuit fault detecting device is made up of following circuit: crystal diode D ₂, light emitting diode D ₄And resistance R ₂Series connection, its positive pole is through the review button AK that resets ₂Connect anodal test contact, negative pole connects the negative pole test contact; Crystal diode D ₁, light emitting diode D ₃And resistance R ₁Series connection, its negative pole is through reset button AK ₁Connect anodal test contact, positive pole connects the negative pole test contact.

Between two test contact described in the technical solution of the present utility model and be connected to the hummer assembly.

The circuit board of the detecting device described in the technical solution of the present utility model is encapsulated in the handle of screwdriver, and screwdriver is as test contact, and the other end of handle is drawn the carp folder that is connected on the lead as test contact; The light emitting diode D of detecting device ₄, D ₃Be installed on the handle.

The utility model is owing to provide a kind of circuit arrangement of accumulator off state indication, can be automatic accurate, detect when intuitively open circuit fault being appearred in accumulator and indicate, and it is easy to operate, fast, both can be used as an independent product, can also pass through expanded function, serving as general screwdriver and portable lamp uses, can be directly installed on the single accumulator again, automatically the open circuit fault that shows accumulator, thereby can promptly fix a breakdown, avoided railway locomotive or used the vehicles of accumulator, because the accident generation that accumulator opens circuit and causes.

Description of drawings

Fig. 1 is an electrical schematic diagram of the present utility model;

Fig. 2 is that single accumulator installs outside drawing of the present utility model additional;

Fig. 3 is the outside drawing that the utility model is made screwdriver.

Embodiment

As shown in Figure 1, the circuit of detecting device 7 comprises the normal working state circuit of detection accumulator and detects accumulator off state circuit, detects the normal operating circuit of accumulator by crystal diode D ₂, light emitting diode D ₄And resistance R ₂Be composed in series, the positive pole of series circuit is by the review button AK that resets ₂Connect anodal test contact 1, negative pole connects negative pole test contact 2, light emitting diode D ₄Can select green light; The circuit that detects the accumulator off state is by crystal diode D ₁, light emitting diode D ₃And resistance R ₁Be composed in series, the negative pole of series circuit is by the review button AK that resets ₁Connect anodal test contact 1, positive pole connects negative pole test contact 2, light emitting diode D ₃Can select to glow; Between positive and negative electrode test contact 1,2 and be connected to hummer assembly 9; Its principle of work is: when carrying out the fault judgement processing, the positive contact 1 of pick-up unit is received battery positive voltage, negative contact terminal 2 connects battery terminal negative, if this battery tension is normal, and green LED D ₄Bright, emitting red light two utmost point D ₃Not luminous; If accumulator opens circuit, red light emitting diodes D then ₃Luminous, green LED D ₄Do not work; Be example explanation with railway locomotive storage battery power supply circuit below: when locomotive storage batteries group 8 voltages just often, locomotive storage batteries 8 voltages are 48 single-unit series connection, voltage is 2 * 48=96V, and the terminal voltage of one case accumulator (four single-unit series connection) is UAB=8V, and positive 8V voltage is through two utmost point D ₂And resistance R ₂Current limliting makes light emitting diode D ₄Sending green glow indicates; When accumulator 8 certain single-unit open circuit, if C point, then the terminal voltage of this case accumulator is UAB=0, when if this moment, locomotive light switch K or accumulator plug-in strip did not disconnect, locomotive storage batteries 8 all the other single-unit series connection by the voltage that is added in behind the load Rfz resistance on this case accumulator are-88V, through diode D ₁And resistance R ₁Make light emitting diode D ₃Send ruddiness and indicate, promptly this circuit can be judged the accumulator open circuit fault rapidly.

Shown in Fig. 2,3, detecting device 7 of the present utility model can be directly installed on the single accumulator, and open circuit fault pilot lamp 3,4 and review button 6 are located on the panel of accumulator, also is provided with positive and negative electrode 1,2 on the panel; The circuit board of detecting device 7 also can be installed in the shell of an insulator, as be encapsulated in the space in the handle of multi-functional screwdriver, screwdriver is as the anodal detection contact 1 of detecting device 7, the other end of handle is drawn lead 5, be connected with crocodile clip on the lead 5, light emitting diode D as test contact 2 ₄, D ₃Be installed in the front end in the handle outside.
