Title:
REFUELING DEVICE
Document Type and Number:
Japanese Patent JP3798820
Kind Code:
B2
Abstract:
PURPOSE: To supply stabilized operating power to a plurality of control means which constitute refueling device.
CONSTITUTION: Mechanisms of a refueling device are controlled by a plurality of control means 32, 33 separately. These control means 32, 33 are housed in explosionproof cases 30, 31 separately and equipped with a common AC-DC converter 24 for supplying D.C. power for the operation. Each of the explosionproof cases 30, 31 houses a DC-DC converter 44 which converts the D.C. power of the AC-DC converter 24 to D.C. power having a voltage suited to the control of the control means 32, 33. Since the DC-DC converters 43, 44 are arranged close to the respective control means 32, 33, the control means 32, 33 can be supplied with DC power at the output voltages of the DC-DC converters 43, 44 without causing a voltage drop in the feeder lines.
