Inventor: ANDOU YORIO
IPC: G01R31/12
Filed: 1981-03-24
Abstract: PURPOSE:To correctly evaluate breakdown due to an electric limit by checking rise in the temperature and thermal breakdown due to the loss of a dielectric with cooling of a UHV cable at a test for withstand voltage or breakdown thereof. CONSTITUTION:When a single-core 2,000mm.<2>OF cable is used for UHV 1,100kV with a low loss synthetic paper employed for an insulator to raise the power transmission efficiency, a thermal stability is attained at a Tc=38 deg.C in the normaloperation. But when subjected to a withstand voltage test at a voltage to ground of 1,270kV, Tc=164 deg.C is given and a thermal breakdown occurs with a sharp increase in the dielectric loss. To preent this, oil of an OF cable hydraulic tank 11 is cooled through a heat exchanger 10 and circulated through a conductor 2 in the route of a refrigerant inlet 7, terminal bushing 5, conductor oil channel 1, a terminal bushing 5 and a refrigerant outlet 8 to cool it 2. This checks the cable from reaching the het range of 150-200 deg.C allowing a thermal breakdown thereby enabling a withstand voltage test to be conducted under a thermally stable condition.

Title: Support for eccentricity measurement
Inventor: NISHI KESAHARU
IPC: G01M1/04
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To facilitate setting and adjustment by changing the material of V block from steel to a resin of ultrahigh molecular weight, especially to a low pressure resin of ultrahigh molecular weight having mean molecular weight within a specified range, thereby making the V block lightweight and convenient. SOLUTION: A V block is made of a low pressure (through light scattering method) resin of ultrahigh molecular weight having mean molecular weight of 3,500,000-4,000,000. Since this material can be machined easily, a V block 1 of appropriate size can be simply cut out from a commercially available planar material. Since this material has specific weight of about 0.94 which is smaller than 1/8 that of steel, i.e., 7.8, weight can be reduced significantly and movement of microdistance and microangle is facilitated thus facilitating setting/adjusting work on a surface plate 6. Friction coefficient to the material of a rotor 2, i.e., steel, is 0.06-0.08 which is a fraction of friction coefficient 0.44 between steel materials. Consequently, the rotor 2 can be rotated smoothly through eccentric measurement, or the like, and the workability can be enhanced while shortening the working time.
