Abstract

The invention discloses a five-prevention control system for a transformer station, and the system comprises a five-prevention main unit, a display, a network controller, a wireless router, a power supply screen cabinet, a centralized control center, a ground line manager host, a detection locking mechanism, and a computer key. The five-prevention main unit is connected with the display, the centralized control center, the network controller and the ground line manager host. The interior of the power supply screen cabinet is provided with a plurality of grounding line devices. The network controller is connected with the wireless router, and the wireless router is used for information interaction between the computer key and the five-prevention main unit. The detection locking mechanism is connected with the ground line manager host. The computer key is used for the unlocking operation and locking operation of the power supply screen cabinet. The computer key carries out the unlocking operation or locking operation of the power supply screen cabinet through a control signal, and the five-prevention main unit controls the display to display the state of the power supply screen cabinet in real time according to the control signal. The system can display the unlocking state or locking state of the power supply screen cabinet in real time, and facilitates the management and maintenance of the grounding line devices in the power supply screen cabinet.

Description

technical field [0001] The invention relates to the technical field of power supply systems, and more specifically, to a five-proof control system for substations. Background technique [0002] In the operation and management of substations, the concept of five defenses refers to anti-load isolation switch; anti-mis-disconnection and mis-closing circuit breaker; anti-load closing grounding switch; [0003] With the continuous development of substation switching anti-misoperation technology, the substation five-prevention control system using a microcomputer anti-misoperation locking device is widely used in the field of five-prevention control, which significantly enhances the reliability of the system and plays a significant role in preventing misoperation accidents. played an important role. [0004] However, when the power supply screen cabinet is unlocked and locked, the current substation five-proof control system cannot display the unlocked and locked status of the po...
