Title:
PASSIVE LOSSLESS SINGLE-PHASE ANTI-ICING AND ICE-MELTING CONTROL DEVICE FOR TENSION TOWER
Document Type and Number:
WIPO Patent Application WO/2023/284014
Kind Code:
A1
Abstract:
A passive lossless single-phase anti-icing and ice-melting control device for a tension tower. The control device is composed of a temperature sensing module (101), a sensing switch module (301), a protection resistor (4), a protection capacitor (5), and a changeover switch (6); three external interfaces are provided and are an input steel core interface (1), an input aluminum wire interface (2), and an output interface (3), respectively; the control device is connected to power transmission lines by means of the external interfaces; and the temperature sensing module (101) is configured to sense the temperature change and control a sliding rod (203) to drive components in the sensing switch module (301) to slide, to turn on/off an ice-melting loop. This control device is light in overall weight; for stock power transmission lines, the tension tower can be directly used without being reinforced; automatic temperature regulation of the power transmission lines can be realized without additional control, and sensing and control in the temperature regulation process are both in a passive mode, and have no electric energy loss; the manufacturing cost is low; the structure is simple; and the reliability is high.
