Industry Background

Solution Overview

The microcomputer anti-misoperation interlocking system consists of hardware and software. Hardware includes computers, computer keys, anti-misoperation locks, and accessories, while software includes anti-misoperation system software, graphic software, multi-tasking operation software, and communication interfaces. The system features equipment status alignment, simulated operations, anti-misoperation interlocking, and operation ticket management. It uses computer keys for on-site unlocking and data reception/transmission, and various locks for on-site equipment locking, preventing electrical equipment misoperation and ensuring safe, controllable disconnector operations.

Solution Advantages

Comprehensive anti-misoperation interlocking

Comprehensive anti-misoperation interlocking

It provides comprehensive anti-misoperation interlocking functions, meeting the anti-misoperation check and mandatory interlocking needs of various electrical equipment types, complex wiring configurations, and flexible operational methods.

Anti-misoperation simulation rehearsal

Anti-misoperation simulation rehearsal

Before operations, the system performs anti-misoperation rule validation through simulation rehearsal, ensuring the operation complies with electrical system safety regulations and equipment operation requirements.

Unique operation right

Unique operation right

At any time, only one person is granted operation permissions for any equipment, preventing misoperation accidents caused by overlapping operation permissions.

High-safety lock

High-safety lock

Blade lock design supports hierarchical and zonal control, meeting high-safety requirements.
