Abstract
A digital detector for charging and discharging of a capacitor is characterized in that two ends of the capacitor are respectively connected with an anode and a cathode of a direct-current digital voltmeter, the anode of the direct-current digital voltmeter is connected with an optional wiring terminal of a direct-current digital ammeter by the aid of a lead, and a wiring terminal of the cathode of the direct-current digital voltmeter and two wiring terminals of the direct-current digital ammeter are respectively led out by the aid of leads. The digital detector for charging and discharging of the capacitor has the advantage that when being used for detecting voltage and charge-discharge current, the digital detector for charging and discharging has the function of eliminating instability of voltage display caused by electromagnetic interference.
Description
Technical field
The charge/discharge detection instrument device of using when the utility model is the motor circuit maintenance is a kind of digital capacitance charge/discharge detection instrument concretely.
Background technology
The charge-discharge circuit of motor vehicle generally adopts multimeter or voltage table and reometer to detect, but exist obviously not enough: because voltage and current must separately be tested, cause loaded down with trivial detailsly when give detecting, the electromagnetic wave of high-voltage ignition coil and magneto generator can disturb the degree of accuracy of demonstration simultaneously.
Summary of the invention
Of the present utility modelly provide a kind of digital capacitance charge/discharge detection instrument, can detect the instrument of voltage and charging and discharging currents simultaneously, have directly perceived, show and understand, can be used as the testing tool of the charge-discharge system of motor vehicle.
The utility model is realized with following technical scheme: this digital capacitor charge and discharge detector mainly is made up of dc digital voltmeter, direct-flow digital ammeter, capacitor.It is characterized in that: the two ends of capacitor are connected with negative pole with the positive pole of dc digital voltmeter respectively, the positive pole of dc digital voltmeter is connected by lead with any binding post of direct-flow digital ammeter, and the negative level binding post of dc digital voltmeter, two binding posts of direct-flow digital ammeter are drawn by lead respectively.During detection, the fuse of vehicle is taken off, two reometer lines that charging detects combination are connected with the binding post of fuse original position respectively, the negative level of voltage table is connected with the negative level of motor vehicle, turn on the power switch, the electric energy of the accumulator reometer of instrument after testing arrives load, and the loaded work piece reometer is walked about, behind the starting motor-driven vehicle, increase along with rotating speed, the electric energy of charger replenishes to accumulator through reometer, and at this moment, reometer is then anti-walks about in the other direction, if ammeter pointer is at negative, represent that then charging current does not reach requirement, ammeter pointer represents then that at positive number charger can be to the accumulator electric energy supplement, when voltage table represents that accumulator is full of during at 15V, being lower than 13.5V is that electric energy is on the low side, is higher than 16V and represents that then charger does not have voltage stabilizing, has realized detecting simultaneously the function of charging voltage and charging and discharging currents.Meanwhile, the electromagnetic wave of magneto generator and high voltage package generation is absorbed by capacitor.
Described capacitor is 25V1000 μ.
The beneficial effects of the utility model are: this instrument has the voltage that elimination brings because of electromagnetic interference (EMI) and shows unsettled function when detecting voltage and charging and discharging currents.
