Title: Transformer
Inventor: OOSHIMA IWAO
IPC: H02B1/20
Filed: 1980-07-29
Abstract: PURPOSE:To prevent the insulation destruction of a transformer due to a surge voltage by inserting a low-impedance device into a transformer connected directly to a gas-insulated switching device. CONSTITUTION:A low-impedance device 11 is inserted between a high-voltage lead 6 of a transformer connected directly to a gas-insulated switching device and an oil/ gas bushing 8 on the gas-insulated switching device side. The low-impedance device has inductance of, e.g. approximately 500muH. The low-impedance device reduces a sharp surge voltage, produced at plug connections in the gas-insulated switching device, before it enters the transformer. The wave front steepness of the surge voltage can be decreased to an allowable wave front steepness of the transformer winding. This prevents the insulation destruction of the transformer.

Title: Reference current source circuit
Inventor: DANMOTO KEIICHI
IPC: G05F3/30
Filed: 1986-05-07
Abstract: PURPOSE:To remarkably reduce the influence of the Early's effect caused by the deviation of current amplification factor beta and the variation of power supply voltage, by using a feedback means to apply the feedback to a reference current value setting transistor. CONSTITUTION:A pnp transistor (TR) 11 detects the Early's effects of both TRs 4 and 5 and the variation of the current amplification factor beta and produces a detection increase current I0. An npn TR 12 and a resistance 13 convert the current I0 into the voltage information to supply it to the bases of the TRs 4, 5 and 6. Thus a loop is formed with these TRs 11 and 12 and resistance 13. While an npn TR 14 serves as a current source TR and supplies a current Iy. The TR 14 also drives a load 16. Then a resistance 15 serves as an emitter resistance and decides the current Iy.
