ща компенсирует т жение провода. Поперечна составл юща компенсируетс усили ми упругих деформаций пружин захватов и усили ми трени . С ростом механических нагрузок до опасной дл целости линии величины поперечна составл юща увеличиваетс в такой степени, что преобладает над компенсирующими ее усили ми, в результате чего происходит автоматическое расцепление захватов 4 и 5, и половины 2 и 3 раздвигаютс , увеличива тем самым длину провода в пролете. При этом стрела провеса провода увеличиваетс и напр жение в проводе ослабевает. Ударна нагрузка, св занна с увеличением длины провода, см гчаетс либо в кольцевом демпфере 6, либо в амортизирующего тросса 7. Предложенна лини электропередачи более удобна и проста в эксплуатации. При срабатывании перемычка не разрушаетс , она обладает многократностью действи . Восстановление нормального габарита линии достигаетс простым сдвиганием частей саморасцепл ющего захвата до сцеплени захватов.conductor compensates for wire strain. The transverse component is compensated for by the elastic deformation forces of the spring grips and the frictional forces. As the mechanical loads grow to the line size dangerous to the integrity, the transverse component increases to such an extent that it prevails over the compensating efforts, as a result of which the grippers 4 and 5 are automatically released, and the half 2 and 3 move apart the span. With this, the sag wire of the wire increases and the voltage in the wire weakens. The shock load associated with an increase in the length of the wire is attenuated either in the annular damper 6 or in the damping cable 7. The proposed transmission line is more convenient and easy to operate. When triggered, the jumper is not destroyed, it has multiple actions. The restoration of the normal gauge of the line is achieved by simply sliding parts of the self-adhering grip to the gripping of the grips.
