摘要：

An insulation strength of more than 16 kV mm-1 has been realized using nitrogen gas at 133 K and 0.4 MPa with the application of a.c. and impulse voltages. A cryoresistive gas insulated line (CRGIL) using nitrogen gas is proposed on the basis of the measured insulation strength. An efficient method for use of the cooling heat of liquefied natural gas is also proposed so that no refrigerator is required and the cost of cooling is reduced. The CRGIL has the advantages of having a large current carrying capacity, small power loss and small capacitance. Moreover, a given transmission capacity is achieved by a CRGIL whose rated voltage is about half that in a conventional gas insulated line. © 1990.
