Relay protection hard strap state collection device

The utility model discloses a relay protection hard strap state collection device. A hardware part comprising a detection host machine, a main controller, a collector and a sensor is adopted. The state collection process comprises the following steps of: detecting the entering/withdrawal state of the protection hard strap by the sensor, transmitting a state signal in a form of high-low levels to the collector, converting the level signal into a massage by the collector and sending the massage to the main controller, forwarding the massage to the detection host machine by the main controller, and displaying the massage in a graphical manner by the detection host machine. According to the relay protection hard strap state collection device, the detection of the protection hard strap state is realized through the sensor, and the state signal is sent to the detection host machine through the collector and the main controller, thereby finally realizing the collection and displaying of the protection hard strap state. The relay protection hard strap state collection device has reasonable structure, can realize the automation of the position detection of the protection hard strap, can collect accurate and reliable position information, and can improve the automation degree of management of the transformer substation.
