On March 18, in the pasture of Gansu Nongken Tianmu Dairy Co Ltd, where over 10,000 Holstein cows grazed peacefully, the electric automatic feeder moved steadily along its track.
"Nowadays, from the initial extensive farming to a more refined and intelligent operation mode, electricity plays a key role." said the production director of Gansu Nongken Tianmu Dairy Co Ltd.
The ranch adopts an open-style cattle house breeding mode. The sprinkler system uses sensing devices to monitor the temperature of both the cattle house and the cattle. When the temperature reaches a critical level, both the sprinkler and fan are activated simultaneously to cool the cattle house. The State Grid Jinchang Power Supply Company has equipped the system with multi-level circuit protection to ensure stable voltage when both the sprinkler and fan are operating simultaneously, thereby avoiding abnormal equipment interruptions. Additionally, in response to the high-load operation of the automatic feed pusher and manure scraper in the cowshed, the company has installed an independent power supply line and added an overload protection device to prevent power fluctuations caused by frequent start-ups and shutdowns.
In the milking workshop, a massive prototype turntable rotates at a steady pace, with cows lining up for automated milking. This sophisticated equipment demands strict power supply. The power company has not only installed redundant power lines but also ensured that the equipment operates reliably throughout the day through dynamic load monitoring and meticulous maintenance. In response to the low temperatures of early spring, the power company's staffs use infrared thermometers to assess the operation status of the distribution cabinets and analyze the power quality of crucial components such as milking machines and milk storage cooling systems using portable detection devices. Additionally, they have intensified inspections of potential hazards at line connections and equipment motors to guarantee consistent and reliable power supply.
To ensure safe electricity usage on the ranch and facilitate the intelligent development of the enterprise, the company regularly provides proactive door-to-door services. They promptly assess the power needs and challenges faced by the ranch, conduct a comprehensive "physical examination" of the power supply lines, switches, voltage boxes, and leakage protection devices in the pastoral area. Additionally, they perform "pulse checking" on equipment such as feed crushers, blenders, lighting, and ventilation systems used in breeding production. Damaged lines are promptly replaced, on-site power usage guidance is provided, and reasonable suggestions are offered to completely eliminate potential safety hazards. By providing "nanny-like" attentive services, the company injects a power engine into the intelligent development and expansion of the enterprise.
From automatic spraying to intelligent milking, from precise feeding to intelligent monitoring, Gansu Tianmu Dairy Co Ltd, with the support of the intelligent power system, has achieved industry-leading levels in key indicators, such as the total number of colonies and protein content in raw and fresh milk, surpassing EU standards. The daily milk output has reached an impressive 34 kilograms per day. Through innovating the "electricity + smart agriculture" service model, State Grid Jinchang Power Supply Company is driving the transformation and upgrading of traditional animal husbandry with reliable electric energy and digital technology, injecting green momentum into rural revitalization.
