How to change a capacitor is taizhou air conditioning capacitor manufacturer

Today as the capacitor manufacturer under the first to introduce the air conditioning is how to change air conditioning capacitor: 1: use soldering iron to dismantle capacitance. 2: install new capacitance. 3: to use. Down to teach people to judge the stand or fall of capacitor, there are the following three methods, consult for everybody to learn: method 1: the most direct the most simple way: use 220 v alternating current (ac) connected directly, we can pick up a pole, with another power cord touch another capacitance feet. In touch to see if there are obvious small spark, is certainly the capacitance charging, that is to say, the capacitance not bad. How air conditioning capacitor in method 2: pointer multimeter, also can use the digital meter capacitance measurement file. If use pointer multimeter, general use R x 1 k file, pens and respectively connected to the poles of capacitance. Multimeter pointer will swing at this moment, then slowly back to zero or near zero. The capacitor is good. The greater the capacity of capacitor, the longer the charge time, pointer swing are more slowly in the direction of 00. If, after connect a pointer still shows very little resistance does not move, you can be sure is bad. Method 3: digital multimeter detection with digital multimeter to check, to set the digital multimeter to the appropriate resistance, red pens and and black pens and contact the poles of the measured capacitor, respectively. At this point, the display value will increase, beginning from 000 until the display symbols '1'. If always shows 000, internal short circuit capacitor. If always show overflow, may be internal capacitor electrode open, may also be a choice of resistance is not appropriate. In order to see from the screen of capacitor charging process, with different capacity of the capacitor should choose different resistance of gear. Select resistance principle is: capacitor is larger, should choose low blocking; Capacitor capacity is small, should choose high resistance. If small capacity were examined with a low blocking capacitor, due to the charging time is short, always show overflow, can't see the change process, which has open easily mistaken for capacitor. If check high-capacity capacitor in high resistance gears, the charging process is very slow, need a measuring time and long. For 0. More than 1 ~ 1000 uf capacitor can choose resistance (according to the following table The charging time in table display file changes from 000 to the time needed for overflow) 。 To measure for the selection of resistance, capacitor, resistance ( Ω） Tested capacitor range ( uF） Charging time ( S20M0。 1 ~ 12 ~ 122 m1 ~ 102 ~ 18200 k10/19 dated to 1003 ~ 2020 k100 ~ 10003 ~ 132 k > 1000 > 3 capacitor after breakdown or open, can't repair, only change is the new capacitor. For ease of repair when choose, in the following table lists the capacity of the capacitor and the compressor motor output power matching, for your reference. Capacitor capacity and compressor motor output power matching compressor motor output power ( W) 0. 2, 0. 4, 0. 75, 1. 0 and 1. 5, 2. 0, 2. 2, 3. 0 and 3. 7, 4. 0, 5. 0; Capacitor capacity ( uF） 15, 30, 40, 50, 20, 30, 50, 50, 75, 75, 100.
