In power systems, substations play a critical role in voltage transformation and power distribution. However, birds frequently nest, roost, and defecate in these areas, posing a significant threat to the safe operation of equipment. A single short circuit caused by bird droppings could trigger a circuit breaker trip, leading to a regional power outage and incalculable losses. How to effectively deter birds without harming them has long been a key concern for operations and maintenance personnel.
In recent years, a smart bird deterrent device based on green laser technology has been playing a significant role in substations. Shenzhen Zhenquniao Technology’s Substation Laser Bird Deterrent ZQN-DL-JG actively deters birds using a green laser beam with a wavelength of 532 nm. The device allows users to preset activation times, patrol modes, and scanning paths. Once activated, the laser beam scans back and forth rapidly and systematically within the designated area, forming a dynamic network of light spots. The irradiation range varies from 3 meters to 200 meters, which is sufficient to cover the critical areas of the vast majority of substations.
Birds are extremely sensitive to moving light spots. When a laser beam sweeps across their surroundings, the rapidly changing light patterns, combined with the faint thermal energy carried by the laser itself, simultaneously stimulate the birds’ visual and sensory systems. Birds instinctively interpret this composite signal as a potential threat, prompting them to fly away quickly. Compared to traditional bird deterrent methods, laser deterrence produces no noise, uses no chemicals, and causes no substantial harm to birds or the environment, making it an effective and eco-friendly control measure.
In terms of power supply design, this device combines solar panels with a battery and can also be connected to the utility grid, making it adaptable to the specific conditions of different sites. With an IP66 protection rating, it offers excellent water and dust resistance, enabling long-term, stable operation in outdoor environments without the need for frequent maintenance.
In terms of practical results, laser bird deterrent systems installed at substations have not only reduced the risk of circuit breakers tripping due to bird-related incidents but have also alleviated the workload associated with manually removing bird nests and droppings. By using light as a barrier, these systems safeguard the safe and stable operation of power facilities without infringing on the birds’ right to live. For the power industry, which is exploring more intelligent and refined approaches to operations and maintenance, this is certainly a technology worth considering.
