Abstract
The invention discloses a high-energy capacity overvoltage absorber, and relates to the technical field of overvoltage suppression of a power supply. The high-energy 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 is taken as a port, the other end of the non-linear resistor FR2 is connected with the one end of the resistor R, one end of the capacitor C and one end of the non-linear resistor FR1 separately, 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 separately connected with one end of the high-voltage fuse RD, and the other end of the high-voltage fuse RD is taken as another port. The high-energy capacity overvoltage absorber has the advantages of high voltage limiting effect, low residual voltage value and high energy gathering and absorbing effect.
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
Several voltages below existing in current 3 35KW power systems: the switching overvoltage of the equipment such as chopper, single-phase gold
The metal produced when belonging to ground connection and arc grounding over-voltage and thunderbolt are the atmospheric over-voltages etc. produced, some peak overvoltages its
The highest possible phase voltage reaching more than 3.5 times of value, if such overvoltage a few hours act on electrical network, will certainly cause electricity
The accumulation damage of insulation in gas 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
It is an object of the invention to provide that a kind of pressure limiting is effective, residual voltage value is low, there is the effect of good cumulative, energy-absorbing
High energy 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 non-linear
Resistance FR1, FR2, high-tension fuse RD, electric capacity C, resistance R；
Described nonlinear resistance FR2 one end as port, the other end respectively with resistance R one end, electric capacity C one end, nonlinear resistance
FR1 one end connect, the resistance R other end, the electric capacity C other end, the nonlinear resistance FR1 other end respectively with high-tension fuse RD one end
Connecting, the high-tension fuse RD other end is as another port.Resistance R, electric capacity C form a hf channel by generation in system
High frequency spikes voltage is transferred to nonlinear resistance FR2, and nonlinear resistance FR2 action absorbs peak overvoltage, and limits high frequency
Peak voltage is less than certain amplitude, thus ensure that and will not produce too high voltages in system, and 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, causes
Make resistance R, electric capacity C-element destroy, therefore when voltage exceedes nonlinear resistance FR1 operation voltage, nonlinear resistance FR1 action is protected
Protect 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 its
Use low dynamic electric resistor zinc oxide valve plate, thus its residual voltage value is greatly lowered, and can well eliminate the guarantor of system overvoltage
Protecting dead band, add its superpower holding, the effective clamping system overvoltage of energy absorption system overvoltage are produced when occurring
Big energy, has good cumulative.The effect of energy-absorbing, can effectively suppress atmosphere over-voltage, switching overvoltage and secondary value relatively
Big arc grounding over-voltage and ferro-resonance over-voltage.
Accompanying drawing explanation
Fig. 1 is the electrical schematic diagram of the present invention.
Detailed description of the invention
Seeing Fig. 1, a kind of high energy holds surge absorber, and it includes nonlinear resistance FR1, FR2, high-tension fuse RD, electricity
Hold C, resistance R, described nonlinear resistance FR2 one end as port, the other end respectively with resistance R one end, electric capacity C one end, non-thread
Property resistance FR1 one end connect, the resistance R other end, the electric capacity C other end, the nonlinear resistance FR1 other end respectively with high-tension fuse
RD one end connects, and the high-tension fuse RD other end is as another port.
The high frequency spikes voltage produced in system is transferred to nonlinear resistance by resistance R, electric capacity C one hf channel of composition
FR2, nonlinear resistance FR2 action absorbs peak overvoltage, and limits high frequency spikes voltage less than certain amplitude, thus
Ensure that and will not produce too high voltages in system, 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, causes resistance R, electric capacity C-element to destroy, therefore when electricity
When pressure 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 its
Use low dynamic electric resistor zinc oxide valve plate, thus its residual voltage value is greatly lowered, and can well eliminate the guarantor of system overvoltage
Protecting dead band, add its superpower holding, the effective clamping system overvoltage of energy absorption system overvoltage are produced when occurring
Big energy, has good cumulative.The effect of energy-absorbing, can effectively suppress atmosphere over-voltage, switching overvoltage and secondary value relatively
Big arc grounding over-voltage and ferro-resonance over-voltage.
