New energy tensioner and control method thereof

Abstract

The invention discloses a new energy tensioner and a control method thereof.The new energy tensioner comprises a tensioner body and a connecting circuit, and the tensioner body is composed of an energy storage module, a first driving unit, a second driving unit, an auxiliary structure unit and an energy recovery module; the first driving unit comprises a frequency converter, a motor electrically connected with the frequency converter through a wire, a speed reducer connected with the motor and a tension wheel connected with the speed reducer, the energy recovery module comprises a first generator, a second generator and a transformer, and the transformer is electrically connected with the energy storage module through a wire; and the first generator and the second generator are electrically connected with the transformer through wires and convert external energy into available energy under the passive rotation of the tension wheel. Due to the fact that the tensioner is in the tension working condition for most of the time, and the motor generates electricity through the tension working condition of the tensioner, test data shows that compared with a traditional tensioner, energy can be saved by 30%-80%.

Description

technical field [0001] The invention relates to the field of tension machines, in particular to a new energy tension machine and a control method thereof. Background technique [0002] Tension machines are required in the tension stringing construction of power line engineering, but the current tension machines are powered by diesel engines, which not only make the equipment noisy, pollute the environment, but also the engine is relatively expensive to maintain and economical. At the same time, diesel is added on site It is also easy to cause pollution. A conventional tension machine is mainly composed of a tension wheel, a deceleration mechanism, a hydraulic system, and an engine. Its working state is generally as follows: when the tension machine is in place, the engine drives the corresponding hydraulic pump to provide pressure oil for the outrigger cylinder to expand and contract; Under working conditions, the engine drives the corresponding hydraulic pump to provide th...
