Correction: Provide a power capacitor and passive power device, especially related to the protection device of the actuator or power capacitor used in the power distribution system to avoid the occurrence of overvoltage or overcurrent in the harmonic distribution phenomenon damage. It can also reduce the inrush current between power capacitors and passive power filters. [Previous technology] Most of the loads in the power distribution system are inductive, and this will absorb the virtual power and cause the backward power factor, making it necessary to send the same expected continuous power with a larger amount, thus reducing the parallel increase of the power distribution system. Voltage regulation at large load terminals. Traditionally, in order to solve the virtual work required by Shangli Company or users to add power capacitor power factor regulators to the power transmission and distribution system to provide inductive loads nearby, the capacity of using power capacitors in the power distribution system accounts for about 25% of s To 35% 'on some systems it can even exceed 50%. Recently, power electronics related equipment has been widely used in power distribution systems (ups), converters (rectifiers), rectifiers (Rectifier), inverters (FreqUency cone converter) (Inverter), etc., and these power electronics related equipment The input is linear and its input power factor is not high. Generally speaking, the frequency of the power distribution system is assumed to be constant, and the power transmission is designed under the condition that the voltage and current waveforms are sine waves. When a large number of such non-linear power electronic devices are used, filter-type power In addition to the system, inductive current is switched on and off before the problem is reported. According to the guarantee filter of the power distribution system, the instantaneous load energy transmission rate due to the current load is

V. Description of the invention (2) Inevitable; pollution, which results in distortion of the system voltage waveform and the quality of the power supply. So in the power distribution system ~ the article on the power capacitors form a passive electric wave cry: often in series harmonics. ❿Power capacitors are connected in parallel to the system: u and the system, passive power filters and power capacitors. Ran wave destruction element. According to a survey conducted by Taipower, the electric power pirate itself is the most susceptible. According to the investigation of Taipower, the passive components in the burned-out components of the electric power ^, 65 ,,, a ^ ^ ^ Passive power filters the problem of harmonic destruction.

Due to the improvement of the system or passive power = In the system, the problem of destroying passive power filters and power capacitors by improving the financial pressure level of power capacitors to improve wave amplification is that this method will raise the cost of the South without indecision. Wave amplified destruction. This C \ L0G0-5 \ FIVE CONTINENTS \ PK8214a ptc 563281 Case No. 91108027 V. Description of the invention (3) In addition, increasing the power capacitor's voltage rating will increase the current resistance value of the inductor. In the case of increasing the rated current of the inductor, once the harmonic amplification phenomenon occurs, it is easy to cause the passive power filter to burn out. This is the main reason for the investigation of the destruction rate of the inductor in Japan [about 65%] is higher than that of the power capacitor [about 2 6%]. the reason. In the prior art, there are methods to cut off the power capacitor when the effective value of the detected current is too high or the total harmonic distortion rate is too high. However, this will lead to the failure of the power factor compensation and cause the power supply voltage of the load to drop. In addition, power capacitors and passive power filters will generate a considerable inrush current at the moment of input, which will not only shorten the power capacitors and passive power; considering the service life of the wave filter, currently special electromagnetic switches must be selected to withstand the larger Transient current. From the above analysis, there is currently no method in the industry that can improve the harmonic resonance and inrush current generated by power capacitors and passive power filters at the same time. Therefore, if the power capacitor and passive power filter are damaged by the overvoltage or current generated by the harmonic phenomenon, the impedance characteristic f [impedance characteristic] can be changed, or the two can be cut off from the power distribution system by using switching elements. Avoid both from being damaged by overvoltage or overcurrent. Cut out of the system from time to time to avoid both being damaged by overvoltage or overcurrent. this

In view of this, in the present invention, an edge protection device is connected in series between the power distribution system and the power capacitor and the passive power filtering circuit. It provides a control circuit to control the opening and closing of the two switches, so that the power capacitor and the passive power filter generate harmonics during harmonic amplification. Before overvoltage or overcurrent, turn on the first switch to add a resistor to the power capacitor and the passive power filter circuit to restore the overvoltage or overcurrent to the normal range; or turn on the second switch to make both ^ 563281 — Emperor 911_97 V. Description of the invention (4) Outside 'In the present invention, the instantaneous power wave circuit is put in, and then the inrush current is reduced. [Summary of the invention] The main purpose of the present invention is the protection device of the wave lifter. When the main switch is on or off, the resistor is put into the switch when the harmonic is put on or off; or the second switch is turned on to cause the two to generate harmonics due to harmonic amplification. The secondary purpose of the invention is to provide a safety device, which mainly turns on the transient current after the first opening period, and the transient current can be closed almost after the first switch [inrush current generated by the instantaneous inrush current according to the invention. Device, which mainly includes a control-resistor. The first switch is connected in series between the power distribution system and the circuit. The control capacitor and the passive power filter current are compared and calculated, and a switch is opened and closed to avoid overvoltage or monthly correction caused by the wave. For a kind of power, it is necessary to use the control to generate overcurrent to protect the power. Over-voltage or a kind of capacitor ^ force capacitor off [the power port is fully attenuated, short-circuit resistor capacitor circuit divides the voltage or passes the container and disconnects the over-current device and the passive and passive device] so by], and the passive type Before the power filter controls the two switching currents, turn on the second passive power filter electric system to avoid damage. The dynamic power filter type power filter passes 1 to 2 power supply cycles after 2 power supply cycles, and can greatly reduce the I input container and circuit in parallel, in parallel with the circuit of the comparator and the circuit to overpower the specific power. The protective device of the passive power filter is equipped with a switch and the resistor to form a circuit. The first force pen valley is' and the passive power filter compares and calculates the function. It compares the voltage or current of the electric power with the rated voltage or the driver ’s result. Control the destruction of the first and third electric valleyrs and passive power filtering, respectively.
