3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Transformer fire with automatic detection, automatic (or manual) start, the control valve to open the oil discharge drain relief, while the cut-off valve can be effectively hindered
Conservator to stop the oil tank and control nitrogen release valve is opened to inject nitrogen inside the transformer fire-fighting equipment. Devices are typically controlled by the fire
System cabinets, fire cabinets, shut-off valves, fire detection and oil discharge nitrogen injection pipe components.
3.2
Gas relay can receive the signal, fire detection devices, fire control cabinet components corresponding actions, like displaying various fire extinguishing equipment
State and can alert the electrical cabinet.
3.3
And controlling nitrogen release nitrogen storage, discharge actuator oil pressure relief. Generally it is having nitrogen storage, nitrogen pressure, nitrogen release, flow
Control, isolation and gas, oil discharge function components.
3.4
After receiving the start signal fire control cabinet operation and can release nitrogen valve.
