Abstract

The invention provides a locking mechanism of a transformer station. The locking mechanism comprises multiple intelligent locking units and an external communication unit. Each intelligent locking unit comprises a master control unit, a first ring network communication unit, a second ring network communication unit, and a forced locking output unit. The multiple intelligent locking units are connected in a way that: the second ring network communication unit of the first intelligent locking unit is connected to the first ring network communication unit of the second intelligent locking unit, the second ring network communication unit of the second intelligent locking unit is connected to the first ring network communication unit of the third intelligent locking unit,..., and the second ring network communication unit of the Nth intelligent locking unit is connected to the first ring network communication unit of the first intelligent locking unit, thus forming a closed annular connection. When the locking mechanism of a transformer station is in a normal working state, dual-ring network redundancy operation is achieved. If a certain node is abnormal, two independent loop networks are realized to keeping running. Therefore, ring network self-healing is achieved, and the stability and reliability of product running are both taken into consideration.
