I. Overview With the rapid development of electricity, people's lives and work are closely related, and sometimes work must be conducted in high-voltage environments. High voltage is extremely dangerous for people, requiring constant maintenance of appropriate distances, especially in various large machinery used in industries such as power, communications, mining, and construction. The operation process is highly challenging, and when operators work in high-voltage environments, psychological pressure arises due to difficulties in judging safe distances, or improper operations may occur, easily leading to contact with high-voltage electricity and resulting in accidents causing vehicle destruction and fatalities. Therefore, high-voltage safety warnings are crucial. The tower crane anti-high-voltage contact alarm is a high-voltage warning device meticulously researched and produced by Telikon for this purpose. II. Working Principle When the tower crane anti-high-voltage contact alarm operates, it extracts the received 50Hz power frequency detection signal, uses digital filtering to eliminate interference signals, analyzes the signal strength, and automatically detects the distance between the equipment and high-voltage lines based on changes in distance and voltage, conducting a series of front-end analysis and processing. When the analysis results reach the preset warning value, it immediately sends a wireless alarm signal to the receiver. Upon receiving the signal, the receiver alerts the user that the equipment is approaching strong electricity, prompting attention to safety. Additionally, during use, the device does not issue warnings for direct current, high frequency, or static electricity. It is primarily used for detecting outdoor overhead lines with voltages above 220V and power frequencies of 50-60Hz. This is because the electric field around a single overhead wire is stable, detection sensitivity is high, and it is easy for the product to receive detection signals. III. Main Features 1. Adjustable alarm distance for the transmitter. The alarm distance is related to the voltage of the strong electricity; the higher the voltage, the greater the power frequency electric field strength generated. By employing different processing networks and setting different voltage levels, it can be configured according to the relevant distances specified by the State Grid. During installation, pay attention to the antenna's angle, direction, and the presence of any obstructions. 2. Flexible and diverse alarm methods. It can output one passive normally open contact, which closes during an alarm, and can add CAN bus and 485 interface control outputs. 3. Supports multiple voltage levels. Currently supported voltage levels include 10KV, 35KV, 110KV, 220KV, and customizable voltage levels. 4. Wide range of applications. It can be used in aerial work vehicles, aerial work platforms, lifting machinery, tower cranes, cranes, and seat vehicles. 5. Flexible power supply methods. Both the transmitter module and the receiver can be powered by DC24V or batteries. 6. Long transmission distance. In wireless mode and without obstacles, the communication distance can reach 200 meters. IV.
