New description: [New technology field] [0001] The present invention relates to a capacitance detection circuit for a capacitor for rectifying and filtering, especially a circuit that can be used in an uninterruptible power system while still operating. A circuit that detects the value of a capacitor by chopping voltage. [Prior Art] [0002] The deterioration of the capacitor will reduce the filtering effect, causing the DC side voltage ripple to cause damage to the energy storage device. However, the energy storage device is a valuable device and is important in the uninterruptible power system. Components, so the protection of the energy storage device needs to be started by the capacitor; the cause of the deterioration of the capacitor is mostly the temperature of long-term operation, so that the electrolyte in the capacitor is dry and the capacitance value of the capacitor is attenuated. In recent years, due to the rapid development of science and technology, various electronic instruments And the use of precision equipment is becoming more and more popular. The more important the requirements for the stability of the power supply system of the uninterruptible power system are. In the operation of the uninterruptible power system, if the degree of deterioration of the DC capacitor is to be detected, the power supply must be switched to another power supply. The power supply is provided, and the uninterruptible power system is tested under the shutdown state; therefore, the present solution solves the above problems, and allows the uninterruptible power system to perform the operation of detecting the capacitor in normal operation without affecting the output side of the uninterruptible power system. Electrical equipment. [New content] [0003] This is a capacitance-decimation line detection circuit for capacitors for rectifying and filtering. In order to overcome the existing capacitors in the detection process, it is necessary to stop the equipment before it can detect the capacitance value of the capacitor. The electrical system is still in operation and does not affect the output of the electrical equipment. Form No. A0101 Page 3 of 18 [0004] M393681 Therefore, the purpose of this creation is to connect a detection circuit to one side of the capacitor. The detection circuit consists of a series of detection switches and resistors, and is used for capacitors and detection. A series isolation device between the output of the circuit and the backup power supply device prevents the backup power supply device from discharging the capacitor and the detection circuit. The isolation device can be composed of a plurality of diodes or a plurality of single-guide-through valve fluids in parallel, thereby avoiding a single failure open circuit Providing a rectified chopping voltage to the capacitor, the rectified chopping voltage is lower than the voltage of the standby power supply device, so that the isolation device isolates the rectified chopping voltage, and the output power is supplied by the backup power supply device; the capacitor receives the rectification The chopping voltage is passed through the conduction detecting circuit to cause the capacitor to perform charging and discharging operations by the resistor, and the capacitance value is calculated from the charging and discharging process. [0005] The present invention improves the detection method of the existing capacitor degradation and uses a rectifier to change Rectified chopping voltage and voltage, and capacitors and resistors In the detection of the capacitance value, the output electrical equipment is powered by the backup power supply device during the detection process, and the output power is not required to be transferred to other bypass power supply during the detection process, and can be detected without stopping the operation. [0006] The present invention is a capacitance value attenuation line detection circuit for a rectifying and filtering capacitor, which can be used to adjust the rectified chopping voltage value by a rectifier in a normal operation of an uninterruptible power system, and can be detected by a resistor of a capacitor and a detection circuit. Capacitance value, the output power during the detection process is supplied by the backup power supply device. If the voltage of the standby power supply device is abnormal, the isolation device can be turned on to make the rectifier chopper voltage supply and output power, so that the output power is not worried about the power failure due to the detection process. [0007] In summary, a capacitor for a rectifying filter has a capacitance value attenuation line form number A0101 page 4 / a total of 18 pages M393681 on the detection circuit, with the following advantages: [0008] 1. Can operate in an uninterruptible power system In the middle, the capacitance value of the capacitor can be detected without affecting the output power device. 2. The isolation device consists of a number of diodes or a number of single-guide-on-gate fluids in parallel to avoid a single fail-open circuit that cannot supply power to the output. [Embodiment] [0009] Referring to Figures 1 and 2, the capacitance detecting line of the capacitor for rectifying and filtering of the present invention includes a rectifying circuit 1. The rectifying circuit 1 is connected in parallel by the digital phase control circuit 11. The phase control circuit 11 is externally coupled with a filter inductor 7 for filtering externally supplied noise. The phase control circuit 11 is composed of a digital thyristor 112 for supplying a rectified continuous wave voltage 9 to the capacitor 2. At least one capacitor 2 is connected to the rectifier circuit 1 and receives the rectified chopping voltage 9 of the rectifier circuit 1. A backup power supply device 3, which is connected to the capacitor 2 for outputting power for detection. The backup power supply device 3 can be an energy storage component 31 of the battery or a DC power supply 32 (as shown in FIG. 3) Show). A detecting circuit 4 connected to one side of the capacitor 2, the detecting circuit 4 comprising at least one detecting switch 41 and at least one resistor 42 connected in series. An isolation device 5 is disposed in series between the output of the capacitor 2 and the detection circuit 4 and the backup power supply device 3 to prevent the backup power supply device 3 from discharging the capacitor 2 and the detection circuit 4; the isolation device 5 can be a diode The body 51 is composed of parallel or a plurality of single-way thyristors 52 in parallel. Please refer to FIG. 3 to avoid a single failure abnormality open circuit and unable to supply power to the output. The single-directional thyristor fluid 52 can be a tamper-controlled rectifier. Form No. A0101 Page 5 of 18 Please refer to Figures 1 and 2. The purpose of this creation is to detect the capacitance value while the uninterruptible power system is still operating, by controlling the number of rectifier circuits 1. The phase control circuit 11 turns off one of the phase control circuits 11 and completely turns on the other digital thyristors 112, so that the rectified chopping voltage 9 supplied to the capacitor 2 is a single-phase full-wave rectified voltage, and the rectified chopping voltage 9 has a maximum voltage Below the output voltage of the backup power supply device 3, the isolation device 5 isolates the rectified chopping voltage 9 with a low voltage, so that the output power of the uninterruptible power system is powered by the backup power supply device 3; when the isolated backup power supply device 3 is completed, it can be turned on. The detecting switch 41 electrically connects the resistor 42 and the capacitor 2, and the resistor 42 of the detecting circuit 4 guides the rectifying chopping voltage 9 to continuously charge and discharge the capacitor 2 to check the voltage maximum value γ 91 .
