Title: Arc time extending circuit for synthetic test of circuit breaker
Inventor: KUROSAWA YUKIO
IPC: G01R31/327
Filed: 1984-04-13
Abstract: PURPOSE:To extend the arc time of a vacuum valve circuit breaker by connecting a capacitor provided near said breaker to be tested to the output terminal of the arc time extending circuit, and further connecting it to an auxiliary breaker through a gap from the terminal of the capacitor. CONSTITUTION:When the auxiliary vacuum valve circuit breakers 4 and 5 to be tested are open and a trigger command is sent out, a trigger gap 12 is discharged and a capacitor bank 17 is charged from a capacitor bank 13 through a resistance 11. Here, the electrostatic capacity value of the bank 17 is set to 1/10 time as large as that of the bank 13 and the gap 18 is set to a gap which is discharged at a voltage lower than the charging voltage of the bank 13; when the terminal voltage of the bank 17 rises up to this value, the gap 18 is discharged automatically and then the bank 17 is short-circuited through the breakers 4 and 5. The wiring length of this short circuit is short and the inductance is low, so an impulsive current on which a high frequency is superposed flows to increase di/dt when the current crosses a zero line, thereby extending the arc time of the vacuum valve circuit breaker.

Abstract: PURPOSE:To obtain a coil whose thermal resistance is excellent and which can maintain a high degree of vacuum by a method wherein a filled layer or/and a coated layer composed of an oxide ceramic are formed at least at one part out of a vacant space between wires of a coil and an external surface part of the coil. CONSTITUTION:After a wire 2 has been wound, a solution reacted with alkoxide is applied to an outer surface if a coil or an individual coil is immersed in the solution so that the solution can be applied to the outer surface of the coil or to a vacant space between wires of the coil. After that, the assembly is heated; a coated layer 3 or a filled layer of an oxide ceramic is formed on the outer surface part or the vacant part between the wires of the coil. This oxide ceramic layer 3 prevents the displacement of a coil winding due to a vibration, and fixes the coil winding solidly; because its melting point is high, its insulating characteristic is excellent even in a high-temperature atmosphere of higher than 500 deg.C. Furthermore, because this oxide ceramic does not become a gas-generating source, it is possible to maintain a high degree of vacuum.
