Description
Technical field
The utility model relates to Hyper-Voltage of Power Systems and suppresses technical field, is specifically related to a kind of high energy and holds surge absorber.
Background technology
There are following several overvoltage in the 3-35KV electric power system at present: the atmospheric over-voltage that produces when the metal that produces when the switching overvoltage of equipment such as circuit breaker, Single Phase Metal ground connection and arc grounding overvoltage and thunderbolt etc., the highest phase voltage that may reach more than 3.5 times of its value of spike overvoltage that has, if high like this overvoltage a few hours act on electrical network, will certainly cause the accumulation damage of insulation in the electric equipment, if the insulation weak link in full phase causes insulation to puncture over the ground, will cause into the major accident of phase fault.
Summary of the invention
The high energy that the purpose of this utility model provides that a kind of pressure limiting is effective, the residual voltage value is low, have an effect of good cumulative, energy-absorbing holds surge absorber.
In order to solve existing problem in the background technology, the utility model is by the following technical solutions: it comprises nonlinear resistance FR1, FR2, high-tension fuse RD, capacitor C, resistance R;
Described nonlinear resistance FR2 one end is as port, the other end is connected with resistance R one end, capacitor C one end, nonlinear resistance FR1 one end respectively, the resistance R other end, the capacitor 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 the another port.Resistance R; capacitor C is formed a hf channel high frequency peak voltage that produces in the system is transferred to nonlinear resistance FR2; nonlinear resistance FR2 action absorbs the spike overvoltage; and restriction high frequency peak voltage is no more than certain amplitude; thereby guaranteed can not produce too high voltages in the system; nonlinear resistance FR1 is resistance R; the protection component of capacitor C branch road; because under characteristic frequency; branch road might produce resonance and too high voltage occur; cause resistance R; the capacitor C component wear; so when voltage surpasses nonlinear resistance FR1 operation voltage, nonlinear resistance FR1 action protection resistance R; the capacitor C element.
High energy of the present utility model holds surge absorber; it not only can suppress the spike overvoltage of system; and because it adopts low dynamic electric resistor zinc oxide valve plate; thereby its residual voltage value just greatly reduces; can well eliminate system superpotential protection dead band; add its superpower holding; can clamp down on the big energy that produces when system's overvoltage and absorption system overvoltage take place effectively; effect with good cumulative, energy-absorbing can effectively suppress atmospheric over-voltage, switching overvoltage and amplitude bigger arc grounding overvoltage and ferro-resonance over-voltage.
