Abstract
A high-capacity overvoltage absorber relates to the technical field of overvoltage inhibition of the power system. The high-capacity overvoltage absorber comprises non-linear resistors FR1 and FR2, a high-voltage fuse RD, a capacitor C and a resistor R, wherein one end of the non-linear resistor FR2 serves as a port while 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; 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; and the other end of the high-voltage fuse RD serves as another port. The high-capacity overvoltage absorber is good in the voltage limiting effect and low in residual voltage value, and has very good energy collecting and absorbing effects.
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
Following several voltage is there is: the metal produced when the switching overvoltage of the equipment such as circuit breaker, Single Phase Metal ground connection and arc grounding over-voltage and thunderbolt are the atmospheric over-voltages etc. produced in current 3-35KW electric power system, the highest phase voltage that may reach 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 of insulation in electric equipment will certainly be caused, if cause insulation to puncture over the ground in the insulation weak link of full phase, the major accident of phase fault will be caused into.
Summary of the invention
The object of this invention is to provide that a kind of pressure limiting is effective, residual voltage value is low, there is good cumulative, the high energy of the effect of energy-absorbing holds surge absorber.
In order to solve problem existing in background technology, the present invention is by the following technical solutions: it comprises 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, electric capacity C forms a hf channel by the high frequency spikes voltage transmission that produces in system to nonlinear resistance FR2, nonlinear resistance FR2 action absorbs peak overvoltage, and limit high frequency spikes voltage and be no more than certain amplitude, thus ensure that in system and can not produce too high voltages, nonlinear resistance FR1 is resistance R, the protection component of electric capacity C branch road, because under characteristic frequency, branch road likely produces resonance and occurs too high voltage, 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.
High energy of the present invention holds surge absorber; it can not only suppress the peak overvoltage of system; and because it adopts low dynamic electric resistor zinc oxide valve plate; thus its residual voltage value just greatly reduces; well can eliminate the protection's dead-zone of system overvoltage; add its superpower holding, can the large energy that produces when occurring of effective clamping system overvoltage absorption system overvoltage, there is good cumulative.The effect of energy-absorbing, effectively can suppress arc grounding over-voltage that atmosphere over-voltage, switching overvoltage and secondary value are larger and ferro-resonance over-voltage.
Accompanying drawing explanation
Fig. 1 is electrical schematic diagram of the present invention.
Embodiment
See Fig. 1, a kind of high energy holds surge absorber, it comprises 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, electric capacity C forms a hf channel by the high frequency spikes voltage transmission that produces in system to nonlinear resistance FR2, nonlinear resistance FR2 action absorbs peak overvoltage, and limit high frequency spikes voltage and be no more than certain amplitude, thus ensure that in system and can not produce too high voltages, nonlinear resistance FR1 is resistance R, the protection component of electric capacity C branch road, because under characteristic frequency, branch road likely produces resonance and occurs too high voltage, 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.
High energy of the present invention holds surge absorber; it can not only suppress the peak overvoltage of system; and because it adopts low dynamic electric resistor zinc oxide valve plate; thus its residual voltage value just greatly reduces; well can eliminate the protection's dead-zone of system overvoltage; add its superpower holding, can the large energy that produces when occurring of effective clamping system overvoltage absorption system overvoltage, there is good cumulative.The effect of energy-absorbing, effectively can suppress arc grounding over-voltage that atmosphere over-voltage, switching overvoltage and secondary value are larger and ferro-resonance over-voltage.
