Abstract
The invention discloses a high-capacity over-voltage absorber, and relates to technical field of over-voltage suppression of power systems. The high-capacity over-voltage absorber comprises a non-linear resistor FR1, a non-linear resistor FR2, a high-voltage fuse RD, a capacitor C and a resistor R, wherein one end of the non-linear resistor FR2 is taken as a port, and the other end of the non-linear resistor FR2 is connected with one end of the resistor R, one end of the capacitor C and one end of the non-linear resistor FR1 respectively; the other end of the resistor R, the other end of the capacitor C and the other end of the non-linear resistor FR1 are connected with one end of the high-voltage fuse RD respectively; and the other end of the high-voltage fuse RD is taken as another port. The high-capacity over-voltage absorber has a good voltage limiting effect, a low residual voltage value and very good energy-gathering and energy-absorbing functions.
Description
Technical field
The present invention relates to Hyper-Voltage of Power Systems suppression technology field, be specifically related to a kind of high energy and hold surge absorber.
Background technology
Current 3 35KW power systems exist following several voltages: the metal produced when the switching overvoltage of the equipment such as chopper, Single Phase Metal ground connection and arc grounding over-voltage and thunderbolt are the atmospheric over-voltages etc. produced, the highest possible phase voltage reaching more than 3.5 times of its value of some peak overvoltages, if such overvoltage a few hours act on electrical network, the accumulation damage insulated in will certainly causing electrical equipment, if the insulation weak link in full phase causes insulation to puncture over the ground, it will cause into the major accident of phase fault.
Summary of the invention
The high energy that it is an object of the invention to provide the effect that a kind of pressure limiting is effective, residual voltage value is low, have good cumulative, energy-absorbing holds surge absorber.
In order to solve the problem in the presence of background technology, the present invention is by the following technical solutions: it includes nonlinear resistance FR1, FR2, high-tension fuse RD, electric capacity C, resistance R；
Described nonlinear resistance FR2 one end is as port, the other end is connected with resistance R one end, electric capacity C one end, nonlinear resistance FR1 one end respectively, the resistance R other end, the electric capacity C other end, the nonlinear resistance FR1 other end are connected with high-tension fuse RD one end respectively, and the high-tension fuse RD other end is as another port.Resistance R, the high frequency spikes voltage produced in system is transferred to nonlinear resistance FR2 by electric capacity C one hf channel of composition, nonlinear resistance FR2 action absorbs peak overvoltage, and limit high frequency spikes voltage less than certain amplitude, thus ensure that and system will not produce too high voltages, nonlinear resistance FR1 is resistance R, the protection element of electric capacity C branch road, because under characteristic frequency, branch road likely produces resonance and too high voltage occurs, cause resistance R, electric capacity C-element destroys, therefore when voltage exceedes nonlinear resistance FR1 operation voltage, nonlinear resistance FR1 action protection resistance R, electric capacity C-element.
The high energy of the present invention holds surge absorber; it can not only the peak overvoltage of suppression system; and because it uses low dynamic electric resistor zinc oxide valve plate; thus its residual voltage value is greatly lowered; can well eliminate the protection's dead-zone of system overvoltage; plus its superpower holding, produced big energy when the effective clamping system overvoltage of energy absorption system overvoltage occur, there is good cumulative.The effect of energy-absorbing, can effectively suppress arc grounding over-voltage and ferro-resonance over-voltage that atmosphere over-voltage, switching overvoltage and secondary value are bigger.
Accompanying drawing explanation
Fig. 1 is the electrical schematic diagram of the present invention.
Detailed description of the invention
See Fig. 1, a kind of high energy holds surge absorber, it includes nonlinear resistance FR1, FR2, high-tension fuse RD, electric capacity C, resistance R, described nonlinear resistance FR2 one end is as port, the other end is connected with resistance R one end, electric capacity C one end, nonlinear resistance FR1 one end respectively, the resistance R other end, the electric capacity C other end, the nonlinear resistance FR1 other end are connected with high-tension fuse RD one end respectively, and the high-tension fuse RD other end is as another port.
Resistance R, the high frequency spikes voltage produced in system is transferred to nonlinear resistance FR2 by electric capacity C one hf channel of composition, nonlinear resistance FR2 action absorbs peak overvoltage, and limit high frequency spikes voltage less than certain amplitude, thus ensure that and system will not produce too high voltages, nonlinear resistance FR1 is resistance R, the protection element of electric capacity C branch road, because under characteristic frequency, branch road likely produces resonance and too high voltage occurs, cause resistance R, electric capacity C-element destroys, therefore when voltage exceedes nonlinear resistance FR1 operation voltage, nonlinear resistance FR1 action protection resistance R, electric capacity C-element.
The high energy of the present invention holds surge absorber; it can not only the peak overvoltage of suppression system; and because it uses low dynamic electric resistor zinc oxide valve plate; thus its residual voltage value is greatly lowered; can well eliminate the protection's dead-zone of system overvoltage; plus its superpower holding, produced big energy when the effective clamping system overvoltage of energy absorption system overvoltage occur, there is good cumulative.The effect of energy-absorbing, can effectively suppress arc grounding over-voltage and ferro-resonance over-voltage that atmosphere over-voltage, switching overvoltage and secondary value are bigger.
