Designing requirement according to all solid state high voltage pulse modulator, when flowing through the fault current of 100kA, all main storage capacitors can carry out energy-absorbing by low sensing resistor, this just requires low sensing resistor can absorb the single pulse energy of nearly 470kJ, and can not explode because of excess Temperature in the maximum fault current situation; Requiring the resistance value of low sensing resistor simultaneously is 180m Ω, and normal working voltage is 23 kV, and running current is 31kA, and making error must not be greater than 2 m Ω.Because above-mentioned designing requirement causes low sensing resistor volume in the market larger, cost is higher, causes the overall cost of all solid state high voltage pulse modulator high.
According to above-mentioned situation, a kind of novel low sensing resistor is provided, the design requirement that satisfies all solid state high voltage pulse modulator with lower production cost is the problem that the prior art needs solve.
Summary of the invention
Technical problem to be solved by this invention is, a kind of low sensing resistor is provided, and satisfies the design requirement of all solid state high voltage pulse modulator with lower production cost.
For achieving the above object, technical scheme of the present invention is that a kind of low sensing resistor is characterized in that: the two ends that described low sensing resistor is coil windings are connected to terminal block, and terminal block is in the homonymy of coil winding; Are connected the edge and adopt the epoxy frame to connect in the both sides that epoxy panel, epoxy base plate are clamped respectively coil winding, epoxy panel with the epoxy base plate.
Space between described coil windings and epoxy panel, the epoxy base plate is integrated poured with epoxide-resin glue, makes coil not loosening, can not occur between the internal resistance coil turn opening circuit, and has increased the overall performance of low sensing resistor.
The material of described coil windings Wei Nie Chrome rod Cr20Ni80 φ 9.
The surface of described epoxy panel is provided with counterbore, utilizes sunk screw and epoxy base plate to be connected and fixed.
The thickness of described epoxy frame should exceed 1-2mm than the height of coil windings.
A kind of low sensing resistor owing to adopting above-mentioned structure, the invention has the advantages that: 1, can according to use occasion require it flexible design to regulate to adapt to different occasions, meet the design requirement of all solid state high voltage pulse modulator; 2, section's filling epoxy resin glue within it, so that the resistance operation is more reliable, performance is more stable; 3, simple in structure, production cost is low, and it is convenient to install.
