Abstract
The utility model relates to a strong strain clamp, comprising a strong strain clamp body made of cast steel, a protect tube made of non-magnetic metal and a U-screw made of non-magnetic stainless steel. The utility model has the advantages of safety and energy saving, simple structure, convenient installation, no wire damage, big intensity of pressure, big friction, clamping force on the wire bigger than the wire breaking force so as to ensure the strong strain clamp to be safer, more reliable and more energy-saving for running.
Description
The powerful strain clamp of the utility model, it is a kind of powerful strain clamp that is specially adapted to overhead transmission line in overhead power line and the transformer station, be a kind of strain insulator intensity big, hold put forth effort big, holding of lead puted forth effort pull-off force greater than lead, powerful strain clamp safe and reliable, energy-conservation, simple in structure, easy for installation.
Existing strain clamp has two kinds of screw bolt-type, crimp types, has lead to get loose when being in operation, and causes the generation of large area blackout.One: its shortcoming of screw bolt-type strain clamp: (1) fastening structure is unreasonable, need during installation by wire clip body, U-bolt, briquetting or pressing plate, the supporting use of metal band, install complicated, be not easy the location, easily damage wires, unit pressure little, hold put forth effort little, since operator's difference, installation quality also different, easily get loose.(2) the wire clip body wire casing degree of depth is less than the lead radius, and the wire casing opening diameter is greater than diameter of wire, and the bottom contact-making surface is a contact, little, the easy damage wires of its attrition surface, easily gets loose when fastening.(3) wire clip body, U type screw, briquetting or pressing plate, by the ferrimagnet manufacturing, form that closed magnet ring, magnetic hysteresis loss are serious, power consumption is big.Its two: its shortcoming of crimp type strain clamp: (1) hold put forth effort little, get loose easily; (2) construction equipment is strongly professional, investment is big; (3) construction manipulation process requires high; (4) wire clamp can not be reused, more than two kinds of form strain clamps holding of lead puted forth effort all less than the lead pull-off force.
The purpose of the powerful strain clamp of the utility model is at the problems referred to above; it is characterized in that by: 1; the powerful strain clamp body (tensile strength is big) of cast steel; 2; the nonmagnetic metal protection tube; 3; non-magnetic stainless steel U type screw (the supporting non-magnetic stainless steel U of powerful strain clamp type screw; needs according to conductor cross-section and pulling force are no less than two non-magnetic stainless steel U type screws); three's combination does not form closed magnet ring to lead; magnetic hysteresis loss is little; form a kind of novel powerful strain clamp, energy-saving safe; simple in structure; easy for installation; damage wires not; unit pressure is big; friction is big; hold and put forth effort greatly; holding of lead puted forth effort pull-off force greater than lead.Make the powerful strain clamp safety and reliability, energy-conservation that is in operation, (one: make 1. wire casing bottom arc boss between the powerful strain clamp bulk line of cast steel trench bottom two holding screws, increase friction with certain altitude; The powerful strain clamp body of cast steel 2. the wire casing degree of depth greater than nonmagnetic metal protection tube radius, increase powerful strain clamp holding contact area, increase friction to nonmagnetic metal protection tube and lead; The powerful strain clamp body of cast steel 3. wire casing bottom radius place combines compactness and is complementary, increases powerful strain clamp nonmagnetic metal protection tube and lead held contact area, increase friction with nonmagnetic metal protection tube external diameter.Its two: the internal diameter of nonmagnetic metal protection tube combines compactness and is complementary, increases powerful strain clamp to the holding contact area, increase friction of lead, non-damage wires with wire diameter.Its three: the opening of non-magnetic stainless steel U type screw combines compactness with nonmagnetic metal protection tube external diameter and is complementary; the compressing power of non-magnetic stainless steel U type screw directly acts on the lead compressing that will be with the nonmagnetic metal protection tube on nonmagnetic metal protection tube and the lead by force and places in the powerful strain clamp wire casing, unit pressure is big, hold put forth effort greatly, damage wires not).Prevent that powerful strain clamp from holding the generation of putting forth effort little, little, the easy damage wires of attrition surface (power), easily getting loose, stop large area blackout.
The powerful strain clamp of the utility model proposes a kind of innovative technology; it is characterized in that by: 1; the powerful strain clamp body (tensile strength is big) of cast steel; 2; the nonmagnetic metal protection tube; 3; non-magnetic stainless steel U type screw (the supporting non-magnetic stainless steel U of powerful strain clamp type screw; needs according to conductor cross-section and pulling force are no less than two non-magnetic stainless steel U type screws); three's combination does not form closed magnet ring to lead; magnetic hysteresis loss is little; form a kind of novel powerful strain clamp, energy-saving safe; simple in structure; easy for installation; damage wires not; unit pressure is big; friction is big; hold and put forth effort greatly; holding of lead puted forth effort pull-off force greater than lead.Make the powerful strain clamp safety and reliability, energy-conservation that is in operation, (one: make 1. wire casing bottom arc boss between the powerful strain clamp bulk line of cast steel trench bottom two holding screws, increase friction with certain altitude; The powerful strain clamp body of cast steel 2. the wire casing degree of depth greater than nonmagnetic metal protection tube radius, increase powerful strain clamp holding contact area, increase friction to nonmagnetic metal protection tube and lead; The powerful strain clamp body of cast steel 3. wire casing bottom radius place combines compactness and is complementary, increases powerful strain clamp nonmagnetic metal protection tube and lead held contact area, increase friction with nonmagnetic metal protection tube external diameter.Its two: the internal diameter of nonmagnetic metal protection tube combines compactness and is complementary, increases powerful strain clamp holding contact area, increase friction, not damage wires lead with wire diameter.Its three: the opening of non-magnetic stainless steel U type screw combines compactness with nonmagnetic metal protection tube external diameter and is complementary; the compressing power of non-magnetic stainless steel U type screw directly acts on that the lead compressing that will be with the nonmagnetic metal protection tube on nonmagnetic metal protection tube and the lead by force places in the powerful strain clamp wire casing, unit pressure is big, hold put forth effort greatly, damage wires not), be a kind of novel powerful strain clamp.
