Abstract

The invention provides a power transmission network iron tower overhead line lightning stroke alarm device. An overhead line is connected between power transmission iron towers, the overhead line is connected with a guide line, the guide line is connected with a mutual inductor, a thunder and lightning signal transmitter is installed under the mutual inductor, and the lower end of the guide line is connected to the ground. The mutual inductor is internally provided with a thunder and lightning coil, the other side of the thunder and lightning coil is provided with an induction coil, the induction coil is connected with a current input module in the thunder and lightning signal transmitter through a power line, the current input module is connected with a transmitting module through a high frequency oscillation module, and the upper part of the transmitting module is provided with a transmitting antenna. The mutual inductor is a current transformer. The transmitting module is internally provided with iron tower position information and an oscillation frequency set value. The power transmission network iron tower overhead line lightning stroke alarm device provided by the invention can sense the position of the iron tower of a lightning stroke point, thereby facilitating checking and maintenance, and has an effect of long-distance communication notification, reducing occurrence of safety accidents, and facilitating management and detection. The power transmission network iron tower overhead line lightning stroke alarm device is suitable for being used as a device for electric power iron tower lighting stroke point notification.

Description

technical field [0001] The invention proposes a lightning strike alarm device for transmission network iron tower overhead lines in the field of electric power. Background technique [0002] In the field of power transmission, for lightning strikes, overhead lines are often used to ground the lightning strike current, which can play a role in lightning protection. But for destructive lightning, the effect of lightning protection is not ideal, and even cause damage to transmission lines and devices, resulting in power outages. After power outages, it is necessary to manually search for lightning strike points and perform maintenance, which consumes man-hours and is difficult to monitor. perception. Contents of the invention [0003] In order to locate the lightning strike point and transmit information, the invention proposes a lightning strike alarm device for the overhead line of the iron tower of the transmission network. The device senses the lightning strike current ...
