AI Technical Summary

Technical Problem

In data center power supply systems, when diesel generator sets are running in parallel, operators may mistakenly operate the output switch cabinet of a non-started unit, causing reverse power supply, resulting in equipment damage and safety hazards.

Method used

A local closing control circuit is set up in the diesel generator output switch cabinet. The auxiliary contact of the circuit breaker test position ensures that the closing operation is allowed only when the circuit breaker is in the test position. The local closing control circuit is cut off to prevent accidental closing. Corresponding control circuits are set up in remote and local operation modes to ensure the safety of closing and opening operations.

Benefits of technology

It effectively prevented back-feeding accidents caused by accidental closing, ensuring the safety of the equipment and operators, and ensuring the stable operation of the power supply system.

Abstract

The application discloses a diesel generator output switch anti-misoperation control circuit and a data center power supply system, and relates to the technical field of data center power supply systems. The circuit comprises an on-site closing control loop which is connected to a local-remote conversion switch, a closing and opening button, test position auxiliary contacts of a circuit breaker and a closing coil of the circuit breaker in sequence after being led out from a positive pole of a control power supply and connected to a negative pole of the control power supply. When the circuit breaker body is in a working position, the working position auxiliary contacts of the circuit breaker are in a closed state, and the test position auxiliary contacts of the circuit breaker are in an open state. Under the condition, when the local-remote conversion switch is switched to a local gear and the closing and opening button is switched to a closing gear, the test position auxiliary contacts of the circuit breaker remain in the open state to cut off the on-site closing control loop. The circuit can prevent the anti-power supply accident caused by misoperation and ensure the stable operation of the power supply system.
