Abstract
The invention discloses a lateral slip measurement unit used for operation of a high-voltage cable laid in a snaking shape. The measurement unit comprises an encapsulated displacement sensor, the measurement end of the displacement sensor is connected with a stainless steel ring buckle, and the other end and the encapsulated bottom end of the displacement sensor are connected with a bottom end fixing device. The stainless steel ring buckle is arranged on a cable sheath at the snakelike wave crest of the cable laid in the snaking shape, and the bottom end fixing device is fixed to the ground. By means of the action of load currents and operation temperature, the cable laid in the snaking shape is lifted to a certain position from the original laying position, and lateral slip is generated; meanwhile, due to change of the load currents and the operation temperature, the lateral slip changes, the displacement sensor needs two-direction measurement, and change of the lateral slip can be measured. The displacement sensor is connected with a signal collecting unit through a signal line, and collecting of displacement signals is achieved.
