When the third electric normally open valve 17 is arranged in the first oil drainage pipeline 1 and the fourth normally open valve is arranged in the second oil drainage pipeline 1, the output end of the controller is connected with the control end of the third electric normally open valve 17 and the control end of the fourth electric normally open valve.
The oil discharge work of the safe intelligent transformer is as follows: at first, the heavy gas trip, the fire alarm signal detection device and the transformer service entrance switch trip mounted on the transformer body send signals to the controller, when the controller receives more than two kinds of signals, the controller sends control signals to the oil discharge pump and the first electric normally closed valve in the first oil discharge pipeline, so that the oil discharge pump starts to work and the first electric normally closed valve is opened, and at the moment, oil in the transformer body is discharged through the first oil discharge pipeline under the action of the oil discharge pump. After the first oil discharge pipeline discharges oil for 10 seconds, the passage of the transformer body and the oil storage cabinet is closed, the second electric normally-closed valve 21 is opened through the controller, and at the moment, oil in the oil storage cabinet is discharged through the second oil discharge pipeline. And after the first oil discharge pipeline discharges oil for 15 seconds, the controller controls the nitrogen charging device to be started, and nitrogen is introduced into the transformer. When oil in the transformer is discharged to the oil level gauge set by the oil level gauge, the oil level gauge sends a signal to the controller, so that the controller controls the first electric normally-open valve and the second electric normally-open valve to be closed, and the oil discharging operation is finished. When the first electric normally closed valve and the second electric normally closed valve break down and cannot be normally opened, the first manual normally closed valve and the second manual normally closed valve on the first branch and the second branch can be opened by the aid of the opening device, so that oil in the transformer can be smoothly discharged. When first electronic normally open valve and the electronic normally open valve of second were closed, the first manual normally open valve of accessible was closed and the manual normally open valve of second realized stopping oil extraction work. If the first manual normally-open valve in the first oil discharge pipeline cannot be closed, the first oil discharge pipeline can stop oil discharge by closing the third electric normally-open valve and the third manual normally-open valve at the downstream of the first manual normally-open valve. If the second manual normally open valve in the second oil discharge pipeline does not work, a processing method similar to that of the first oil discharge pipeline can be adopted for processing.
Foretell safe intelligent transformer through setting up the quick oil fire separator mentioned before, can discharge the oil in transformer body and the oil conservator fast for when the transformer is on fire, the oil in the transformer discharges fast, realizes the oil fire separation, prevents that the intensity of a fire from expanding and avoiding exploding, and then has guaranteed staff's personal safety, has reduced economic loss. This safe intelligent transformer fills nitrogen in to the transformer through filling nitrogen device, can effectual control stretching of intensity of a fire, avoids the intensity of a fire to enlarge, and then has improved the security. In addition, through setting up the first branch road that has normally closed valve, the second branch road that has the manual normally closed valve of second and the manual normally open valve of third and the manual normally open valve of fourth, ensure that this safe intelligent transformer can deal with proruption trouble for this safe intelligent transformer can the operation of safety and stability, further improved the security.
