Embodiment Construction

[0043] The specific embodiments of the present invention are as figure 1 , figure 2 and image 3 Shown.

[0044] The starting line rod 1 and the finishing line rod 14 are two adjacent line rods erected on the ground 13. The high-voltage power transmission bus bar 2 is erected between the start line pole 1 and the finish line bar 14, and its center line is the bus main shaft 40. When the high-voltage power transmission bus 2 is tightly installed, the bus main shaft 40 can be approximately regarded as a straight line. When long-term low temperature weather occurs in winter, the high-voltage power transmission bus 2 may be iced, and the online automatic laser ice-covering detection and ablation system of the present invention can realize automatic deicing.

[0045] The implementation process of this embodiment is as follows:

[0046] The online automatic laser ice coating detection and ablation system is composed of a transmitting box 4 and a receiving box 10. The launching box 4 i...

Abstract

A high-voltage power-transmission bus-line on-line automatic laser icing detection and ice melting system comprises an emission box (4) and a receiving box (10). The emission box is fixed to a high-voltage power transmission bus line starting point line rod (1) through an emission box fixing arm (3). The receiving box is fixed to a high-voltage power transmission bus line terminal point line rod (14) through a receiving box fixing arm (15). An emission box master control system is used to control emission of an impulse ice melting laser (7) and a detection laser (8). A receiving box master control system is used for making a photoelectric detector (12) receive a signal. The detection laser is used for detecting icing and the impulse ice melting laser is used for ice melting. In the invention, high-voltage bus line induction electricity taking is adopted; extra power supply is not needed and persistence of system working is guaranteed. An on-line automatic detection and automatic ice melting integrated design is used and intelligence is possessed. Through adding a wireless network, remote control and system software upgrading can be realized. The system can carry out deicing when a power grid with a load operates an environment adaptability is high.

Description

[0001] technical field [0002] The invention relates to an on-line automatic laser ice detection and ice melting system for a high-voltage power transmission bus, belonging to the technical field of laser applications. Background technique [0003] When long-term low-temperature weather occurs in winter and causes large-scale meteorological disasters, water, electricity, and gas are often cut off in cities, and public transportation will also be partially interrupted. The direct cause is often a power outage. The reason for large-scale power outages in winter is that the power supply line is covered with ice, which will double the weight of the high-voltage transmission bus, thereby breaking the line or breaking the pole and iron tower. [0004] Therefore, an efficient and practical method for removing icing on high-voltage transmission busbars is a very urgent and powerful measure to ensure normal power supply in winter. High-voltage transmission busbars usually have high...
