Abstract

The invention discloses a laser deicing device and method for a transformer substation. The device comprises a coaxial aiming unit which is used for outputting colored indication laser coaxial with deicing laser through a collimating lens, and aiming at a deicing point on to-be-deiced equipment, a laser driver which is used for outputting deicing laser to the deicing point on the to-be-deiced equipment to melt ice, an infrared temperature measurement module which is used for measuring the real-time temperature of the deicing point and feeding back the measured temperature to a control module,and the control module which is used for receiving the real-time temperature of the deicing point from the infrared temperature measurement module, and controlling an X / Y double-axis steering machineto adjust the laser driver to output deicing laser to a next deicing point when the real-time temperature of the deicing point exceeds a deicing temperature threshold. According to the invention, thecoaxial aiming unit adopts laser aiming indication to assist deicing laser in quickly positioning a deicing position, and can automatically move to the next deicing point when the temperature of the deicing point exceeds the limit, so as to protect the to-be-deiced equipment.

Description

technical field [0001] The invention relates to the technical field of protection for power transmission equipment, in particular to a laser deicing device and method for substations. Background technique [0002] Large-scale rain and snow freezing is the biggest disaster for the safe operation of the power grid. Icing on the external insulation of substation equipment will lead to flashover of insulators, tripping of lines, and outage of substations due to voltage loss, which will seriously affect the safe and stable operation of the power grid. During the ice disaster in 2008, many 220kV and above substations were out of service due to ice flashes on pillar insulators; in 2016, Hunan 220kV Lujia Substation and other substations were out of service due to ice flashes. [0003] Therefore, after the external insulation of power grid equipment is iced, it is of great significance to safely and effectively de-icing quickly. The laser has the characteristics of high power and ...
