Abstract
Withstand voltage detection device of power capacitor metallized film, including voltage regulator TA, voltage regulator TA couples step up transformer T, and step up transformer T couples bridge rectifier U, the flat ripples condenser C1 of bridge rectifier U hookup, flat ripples condenser C1 hookup test article C2. In operation, single -phase power frequency alternating current passes through the lift of voltage regulator TA calibration voltage, again with the voltage input step up transformer T after the pressure regulating of voltage regulator TA, the voltage (high pressure) of step up transformer T secondary side, after the bridge rectifier U rectification, flat ripples through the direct current support condenser C1 on the DC voltage that connects in parallel, formal withstand voltage detection power as test article C2 ( model of metallized capacitor ), carry out the inspection of anti voltage strength, the model of metallized capacitor who convolutes out to the initial workpiece carries out the test of component method, the production of having passed through the test can continue to be used for processing, otherwise just stop production immediately, seek solution method, it goes on smoothly to ensure production.
Description
Technical field
This utility model relates to a kind of power capacitor metalized film overpressure resistance detecting device, belongs to electrical equipment field.
Background technology
Metalized film is to manufacture the topmost raw material of low voltage power capacitor, this most important material specification is lacked measuring means by overwhelming majority manufacturing enterprise in process of production, surveys the thickness of metalized film, measures the square resistance of a lower metal layer, look at that outward appearance is with or without serious gauffer, not much else.For the considerable index of this material: dieletric strength cannot detect and differentiate, once raw material is become capacitor element, the metalized film of hundreds and thousands of kilograms has flowed among each operation on a production line, if finding material reactance voltage existing defects at last several procedures, then late, wasting material, manpower and time does not say, it is also possible to delayed the payment of user.Accordingly, it would be desirable to develop a kind of device that element is carried out dieletric strength detection, to guarantee that what produce is smoothed out.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, it is provided that one can be used for capacitor metalized film reactance voltage intensity detection, it is ensured that produce the power capacitor metalized film overpressure resistance detecting device being smoothed out.
The technical scheme of this utility model power capacitor metalized film overpressure resistance detecting device is: it is characterized in that including pressure regulator TA, pressure regulator TA couples booster transformer T, booster transformer T couples bridge rectifier U, bridge rectifier U couples smoothing capacitor C1, smoothing capacitor C1 and couples test article C2.
Power capacitor metalized film overpressure resistance detecting device of the present utility model, during work, single phase industrial frequence alternating current adjusts the lifting of voltage by pressure regulator TA, again the voltage after pressure regulator TA pressure regulation is inputted booster transformer T, the voltage (high pressure) of booster transformer T secondary side, after bridge rectifier U rectification, the flat ripple of the direct current support capacitor C1 on DC voltage in parallel, formal as the capacitor metalized film of test article C2() resistance test power supply, carry out reactance voltage ruggedness test, the capacitor metalized film winding out to initial workpiece carries out element method test, the production having passed through test can continue on for processing, otherwise just stop immediately producing, seek solution, guarantee that production is smoothed out.
Accompanying drawing explanation
Fig. 1 is this utility model power capacitor metalized film overpressure resistance detecting device principle schematic.
Detailed description of the invention
This utility model relates to a kind of power capacitor metalized film overpressure resistance detecting device, as it is shown in figure 1, include pressure regulator TA, pressure regulator TA couples booster transformer T, booster transformer T couples bridge rectifier U, bridge rectifier U connection smoothing capacitor C1, smoothing capacitor C1 and couples test article C2.During work, single phase industrial frequence alternating current adjusts the lifting of voltage by pressure regulator TA, again the voltage after pressure regulator TA pressure regulation is inputted booster transformer T, the voltage (high pressure) of booster transformer T secondary side, after bridge rectifier U rectification, the flat ripple of the direct current support capacitor C1 on DC voltage in parallel, formal as the capacitor metalized film of test article C2() resistance test power supply, carry out reactance voltage ruggedness test, the capacitor metalized film winding out to initial workpiece carries out element method test, the production having passed through test can continue on for processing, otherwise just stop immediately producing, seek solution, guarantee that production is smoothed out.This device also can be arranged component breakdown voltage show, component pressure detection the function such as complete automatic discharging and zero potential startup, it is simple to test.
