Transformer working condition
After the operation of the transformer state of operation is divided into four states, namely, running state, hot standby state, cold standby state and maintenance state.
Operation status: The circuit breaker and isolation switch of the transformer are all in the working state of closing position;
Hot standby state: The transformer only disconnects the circuit breaker and the disconnector is still in the non-operating state of the closing position;
Cold Standby: Transformer circuit breakers and disconnectors are in non-operating state at the opening position.
Maintenance status: All circuit breakers and disconnectors of the transformer have been disconnected, and the non-operational state of safety technical measures such as installing the grounding line, hanging the nameplate, and setting temporary barriers has been completed.
