Description

The capacitor charge and discharge exerciser

[technical field]

The utility model relates to a kind of exerciser, particularly a kind of capacitor charge and discharge exerciser.

[background technology]

At present, electric capacity is extensively used, because there are quality problems in some electric capacity, for example capacity has deviation, usually causes the circuit paralysis in use, thereby influences the operate as normal of relevant device, therefore, guarantees that the quality of electric capacity is very important well.

[utility model content]

The technical problems to be solved in the utility model provides a kind of capacitor charge and discharge exerciser, can discharge and recharge test neatly to different electric capacity so that the quality situation of monitoring electric capacity neatly.

Above-mentioned technical matters solves by the following technical programs:

A kind of capacitor charge and discharge exerciser, it is characterized in that, comprise that one connects adjustable DC power supplier, a power switch, a voltage display module, one first contactor, capacity measurement folder, one second contactor, a discharge coil, a control module and an artificial load module of civil power; Chuan Jie first contactor, power switch and adjustable DC power supplier are connected the two ends of capacity measurement folder successively, second contactor of serial connection and discharge coil are connected the two ends of capacity measurement folder, described voltage display module is used to show the output voltage of described adjustable DC power supplier, described artificial load module is used for duration of charging, discharge time being set, discharging and recharging number of times and opening the charging experiment by the user, and described control module is used to receive the signal of artificial load module to control the break-make of first contactor and second contactor.

Described voltage display module comprises a correction resistance and a voltage table of serial connection.

Described adjustable DC power supplier comprises that successively one of serial connection is used to connect regulating circuit, a step-up transformer and a pair of full-wave rectifying circuit of civil power.

Described adjustable DC power supplier comprises that successively one of serial connection is used to connect the regulating circuit and a pair of full-wave rectifying circuit of civil power.

As seen from the above technical solution, the utility model is adjusted charging voltage so that different electric capacity are charged by adjustable DC power supplier is set, and by artificial load module electric capacity is discharged and recharged test neatly, thereby is convenient to monitor the quality situation of electric capacity.

Fig. 3 is the another kind of concrete synoptic diagram of adjustable DC power supplier of the present utility model.

[embodiment]

As shown in Figure 1, the utility model comprises that one connects adjustable DC power supplier, a power switch, a voltage display module, one first contactor, capacity measurement folder, one second contactor, a discharge coil, a control module and an artificial load module of civil power, wherein, this voltage display module comprises a correction resistance and a voltage table of serial connection, can be that voltage table shows the step-down that virtual voltage carries out equal proportion by proofreading and correct resistance; Chuan Jie first contactor, power switch and adjustable DC power supplier are connected the two ends of capacity measurement folder successively, second contactor of serial connection and discharge coil are connected the two ends of capacity measurement folder, this voltage display module is connected the two ends of adjustable DC power supplier, artificial load module is used for duration of charging, discharge time being set, discharging and recharging number of times and opening the charging experiment by the user, and control module is used to receive the signal of artificial load module to control the break-make of first contactor and second contactor.

Its principle of work is:

The user is connected to the capacity measurement folder with electric capacity, turn on the power switch after the voltage of adjustable DC power supplier adjusted to minimum voltage, according to test request, at artificial load module be set the duration of charging, discharge time and charging times, till slowly the adjustable DC power supplier of adjustment is shown as suitable voltage down to output voltage to voltage table then, open the signal of charging experiment in artificial load module input again, the test that this exerciser repeatedly discharges and recharges electric capacity automatically, discharge and recharge all is to charge earlier with afterwards discharging at every turn, specifically: closed and second contactor disconnection of first contactor, after charging reached setting-up time, first contactor disconnected, and promptly charging circuit disconnects, the second contactor closure then, the electric capacity two ends are connected in the discharge coil automatically discharges, and arrives when discharge time, and second contactor disconnects, the first contactor closure, so circulation till having arrived experiment number, stops test automatically.

By electric capacity is discharged and recharged test, again this electric capacity is carried out capacity check, as the discovery capacity deviation is arranged, then judge this electric capacity existing problems, can in time solve, thereby can monitor the qualified situation of electric capacity.

Usually, according to the electric capacity of different capabilities, in discharging and recharging process of the test, require the voltage difference of adjustable DC power supplier output, therefore, for the electric capacity of corresponding different capabilities, adjustable DC power supplier is different.As shown in Figure 2, for the bigger electric capacity of capacity, adjustable DC power supplier comprises that successively one of serial connection is used to adjust regulating circuit, a step-up transformer and a pair of full-wave rectifying circuit of civil power; For test CBB61 electric capacity, adopt 0V～250V pressure regulator and 0～1500V step-up transformer.As shown in Figure 3, for the less electric capacity of capacity, adjustable DC power supplier comprises that successively one of serial connection is used to adjust the regulating circuit and a pair of full-wave rectifying circuit of civil power, does not promptly need the voltage after the pressure regulation is boosted.

The utility model is not limited to the foregoing description, based on simple replacement the foregoing description, that do not make creative work, should belong to the scope that the utility model discloses.
