The utility model provides a superfrequency sensor for cable partial discharge detector, includes: double-phase with first, the oval metal paster antenna of second, two gold medals belong to the parallel symmetrical arrangement of paster major axis, leave the clearance each other, one uses relative dielectric constant to be the square medium base plate 3 that 2-6 insulating material made, a hexahedron metallic shield box 4, a coaxial line 5 connects 6 with the N type, first, second metal paster 1, 2 cover respectively in the surface of medium base plate 3 to the symmetry is in 3 axis of medium base plate, medium base plate 3 is fixed in metallic shield box 4, the sinle silk of 5 one end of coaxial line and shielding layer two minor axis summits, the other end connected in that metal paster 1 and metal paster 2 are close to mutually of electricity respectively connected for 6 electric connections with the N type, the N type connect 6 and fix on metallic shield box 4. The utility model has the characteristics of small, the directionality good, sensitivity is high to it detects not enough with the superfrequency sensor to compensate in the past the cable.
