To reflect the needs of the enterprise municipal government coordinate and solve the problem, even Viljandi separately proposed a solution and vgp-bps2 , vgp-bps2a , vgp-bps2b ideas. He said he would clear a city leadership and the Municipal Science and Technology Bureau of affiliated enterprises, ready to help companies coordinate and solve related problems. For enterprises to build provincial engineering technology research center, the city will come up with some science and technology in the three funds of funds to support it.
Pressure testing and application of electrolytic capacitors
For the electrolytic capacitor, leakage current is an important performance indicators. Electrolytic vgp-bps2c , VGP-BPL2 capacitor leakage current and voltage is closely related to leakage current with the operating voltage of the higher and increasing. When working voltage close to the anode enabling voltage, leakage current will rise sharply. By testing electrolytic VGP-BPL2C capacitor leakage current, one can calculate the limits of its voltage and rated voltage, capacitor voltage for the circuit values, there is a direct reference to the meaning.
According to this principle, designed and produced ~ section capacitor voltage tester, the circuit simple and low cost, making easy to satisfactorily solve the amateur capacitance pressure test under the conditions of the problem.
Transformers T1 and T2 models the same as back to back dock, provide two sets of high and low voltage power supply, and to play a role in isolation. Low pressure, filtered through the rectifier, from R1, DWl, Q1, Ral ~ Ral1 composed of current adjustable constant current source. High-pressure filtered through the rectifier after the Rbl ~ RblO, DW2 partial pressure, Q2 output adjustable DC voltage. Use select the appropriate voltage Uc and current sony vgp-bps2 , sony vgp-bps2a , sony vgp-bps2b Jc, the measured capacitance will receive Cxa, Cxb 2:00, the time will see the slow voltage meter pointer deflection, static up to a certain location, the pointer shall be referred to the voltage of the lc capacitor leakage current when the pressure to bear.
Band switch K3, K4 (the single block 11), respectively to test the voltage and current (ie leakage current) selector switch, its test range as shown in Table 1.
1, the test circuit to use
1. Transferred to the test voltage is higher than the capacitor voltage of gear. 35V, such as testing of Shen Rong. Gear can be put 64V, testing 50v capacitor can be put gear 64M or 96V. Higher gear little effect on the test results sony vgp-bps2c , sony VGP-BPL2 , sony VGP-BPL2C, but the higher gear, the corresponding power transistor Q1 will be larger.
2. Select the appropriate test current. Test current should be based on capacitance to choose, the greater the capacity the greater the test current. For more than 4700μF capacitor can choose more than 10mA test current; for 1000 ~ 4700μF of electricity, capacity, choose a test current of 5mA or so: For the 10μF capacitor below the option of 0.2 ~ 1mA of test current.
3. Then the red alligator clip capacitor anode, black alligator clip then capacitor anode. Then, after a good pointer to the first uniform voltage meter to see the slow deflection. Deflection of position under normal circumstances should be more than rated voltage, when it reaches a certain value, the pointer deflection of its slow and getting slower and slower and eventually still down, this time capacitor leakage current is equal to Q1 collector of the constant current, voltage table direct voltage, this capacitor leakage current Ic when the bear pressure, can be roughly considered as the limit of the capacitor voltage.
4 test is completed, will switch K2 is closed until after sony vgp-bps2 battery , sony vgp-bps2a battery the capacitor discharge removed.
2, the test lessons learned
1. Capacitance larger, the test current (leakage current) should also be accordingly larger.
Domestic aluminum electrolytic capacitor at rated voltage of 6.3 ~ 450V, the nominal capacity of 10 ~ 680μF, the leakage current can be calculated as follows:
I ≤ (KxCxU) / 1000
Formula:
I for the leakage current (mA);
K coefficients (20 ℃ ± 5 ℃, when, K = O.03)
U for the rated voltage (V);
C for the nominal capacity (μF):
2. As the electrolytic capacitor can only be one-way, such as the electrolytic capacitor termination of plus sony vgp-bps2b battery , sony vgp-bps2c battery or minus anti-testing, testing in the 5mA current, voltage very low, only about 4V or so.
3. A long-term unused electrolytic capacitors, due to the decomposition of oxide film, capacity, pressure has a certain amount of attenuation in the first use, should increase low-voltage (1 / 2 rated voltage) the aging period of time (equivalent to electrolytic capacitors Fu energy).
4. The same capacity and voltage of the electrolytic capacitor, its larger, heavier weight better performance of the general pressure; the same capacity and voltage of the electrolytic capacitor, its the same test current, voltage, fast pointer deflection, leakage current smaller.
5. Genuine sony VGP-BPL2 battery , sony VGP-BPL2C battery electrolytic capacitor voltage limit of normal for 120% of rated voltage.
6. When working voltage is higher than the rated voltage, capacitance easier to breakdown. Therefore, use electrolytic capacitors should be so rated voltage higher than the actual operating voltage, and to allow a certain amount of cushion to cope with voltage fluctuations. Under normal circumstances, rated voltage should be higher than the actual operating voltage of 10% to 20%, less stable operating voltage for the circuit, may be more appropriate reserve margin.
7. Using this circuit testing electrolytic capacitors, capacitor will not cause damage.
3, test circuits to improve
1. In the absence of a suitable voltage fujifilm battery , fujifilm np-100 battery to purchase header, DC250V block can not be directed above. If you can replace the DC320v header on the ideal. Header span is also not too large, otherwise it will reduce the resolution, the use of such headers to test low-voltage capacitor, it will result in reading too much bias.
2. In order to obtain more accurate test voltage can be Rbl ~ Rbl0 divider resistors replaced by the corresponding value of regulator voltage regulator tube (plus current-limiting resistor) or multi-ring precision adjustable resistors.
3. V1, if replaced by a digital voltmeter, the voltage reading will be more intuitive and precise. However, an additional group of DC5v installing a floating power supply.
4. Constant resistance Ral ~ Rall, if using a 47 ∞ a 4.7kΩ resistor in series Multi-turn fujifilm np-120 battery , fujifilm np-140 battery precision potentiometer instead, its constant value (1.1 ~ 12mA) can be continuously adjustable.
4, testing the expansion of circuit functions
In addition to testing electrolytic capacitors, the meter can also test some parameters in the following components:
1. Thin-film capacitor voltage. The limits of thin-film capacitor voltage is generally higher than the rated voltage of 50% ~ 100%, the test block select small current (<lmA), voltage is selectable 2 times rated voltage. The same capacity of the capacitor, charge faster, smaller leakage current and loss, the better the quality. Metallized film capacitors in the test, such as a slight to hear pops, indicating a partial breakdown in its internal, should reduce the test voltage.
2. Varistor voltage protection. Voltage blocking fujifilm np-150 battery , fujifilm np-30 battery , fujifilm np-40 battery and current block can be placed in the biggest gear test, voltage meter shall be first referred to the protection of varistor voltage.
3. LED's operating voltage. As the LED's operating voltage lower (1.5-3V), need to Cxal, Cxbl at parallel digital voltmeter, the current gear selection 5 ~ 10mA, a digital table reading.
4. Diode reverse breakdown voltage. For the 1N4001 series of pressure, its value is less than 250V for plastic diode, the current block option lmA, voltage block transferred to the maximum, using voltage meter to read out the first of its reverse breakdown voltage.
5. Regulator diode voltage. Current block transferred to 1 ~ 5mA, block may be slightly higher than its rated voltage fujifilm np-50 battery , fujifilm np-80 battery , fujifilm np-95 battery, the voltage meter read out of the head regulator diode actual value.
