40、acitors shall be capable of releasing any excessive internal pressure without violent expulsion of capacitor element or cover or emission of flame, when rated ac rms voltage 60 Hz is applied continuously to a capacitor. 16 Accelerated life test 16.1 Capacitors shall be capable of withstanding life t
41、est in a 65C 3C ambient at rated sinusoidal voltage and frequency with current limiting and discharge resistors. A resistance equivalent to approximately 10% of the capacitor impedance shall be connected in series with each capacitor and a resistor of approximately 1000 ohms shall be connected in pa
42、rallel with each capacitor. Life test shall be conducted in a test chamber with capacitors separated by at least 25 mm (1 in) of air and with sufficient circulation so that the ambient temperature remains within the above temperature limits and does not vary more than 1C; also capacitors shall not b
43、e exposed to direct radiation from heating elements. Test voltage is applied to the capacitor resistor combination. Special test conditions for type 1 and type 2 capacitors are given in detail No. 1 and No. 2 respectively. 16.1.1 At the conclusion of the life test, at room temperature, the capacitan
44、ce shall not differ from the initial measured value by more than 25% and the power factor shall not exceed 20%. 16.1.2 Number of samples and allowable failures shall be as per 6.2. 17 Applications 17.1 Normal service conditions The useful life of a capacitor will be shortened by exceeding the rated
45、voltage and/or temperature limits. In general, as voltage increases, capacitance and power factor increase. Also, as temperature increases, capacitance and power factor increase. The maximum temperature of these capacitors is affected by the condition of air circulation (from dead air condition to a
46、 maximum), by radiated and/or conducted heat, altitude and any other ambient conditions in addition to the heat developed in the capacitor by the application of voltage and the flow of current. The application of a capacitor to a motor must include consideration of these factors. When the motor and
47、capacitor are enclosed in other equipment, the temperature of a capacitor must be considered with the equipment exposed to the highest ambient temperature at which it is designed to operate and after the equipment has reached its maximum operating temperature. 17.2 Mounting EIA-463-B Page 13 Vertica
48、l mounting of the capacitor with the terminals up is recommended; however, horizontal mounting is acceptable. Vertical mounting with terminals down is not recommended and could impair the operation of the pressure relief vent. 17.3 Low temperature When these capacitors are exposed to reduced tempera
49、ture down to -40C and are called on to start a motor, they will respond quickly. At -40C the capacitance is low and power factor high so the application of the voltage to the capacitor causes it to heat up internally in a short time to the point that the capacitance is high enough at a low enough power factor for the motor to start. 17.4 Duty cycle 17.4.1 The duty cycle of an ac motor start capacitor may be determined by dividing the capacitors on-ti
