Title: Interruption test circuit for switch
Inventor: TAKAHASHI NORIYUKI
IPC: G01R31/327
Filed: 1992-12-17
Abstract: PURPOSE:To provide an interruption test circuit for switch which is almost equivalent to ones in actual use because almost the same interrupting current as the zero miss current generated actually can be obtained and which is available for a long arc time test thanks to a simple construction. CONSTITUTION:After a short-circuit generator Gen is energized, a making switch SM is turned on at the voltage where a sample switch SP is applied with a specified current, and two-phase short-circuit current flows in A and B phases. Then, an auxiliary making device SM2 in C phase is turned on to flow three-phase short-circuit current. Since the peak value of AC current flowing during three-phase short-circuiting becomes smaller than that of DC current applied during two-phase short-circuiting, a zero miss current Ip is generated. The switch SP is opened at the time before the arc time is to be verfified from an interrupting performance verification point. An auxiliary breaker SH cuts off the switch SP from the power supply at current zero point. The voltage source applies the charge from a main capacitor Cs on the switch SP as the specified transient recovery voltage and recovery voltage.

Title: Squelch circuit
Inventor: KITAI YOSHIHISA
IPC: H04B1/10
Filed: 1989-12-27
Abstract: PURPOSE:To prevent a change in impedance when a power of a next-stage amplifier is turned on/off with the squelch operation by interposing a buffer amplifier between a pre-stage amplifier and a next stage amplifier. CONSTITUTION:An output of an amplifier 1 is detected by a detector 4 and its level is compared with a squelch level at a comparator 5. When a reception input electric field reaches a squelch point or below, a muting control circuit 6 is activated to turn off the power supply of the amplifier 3. In this case, the power of a buffer amplifier 2 is turned on as it is and its input impedance is unchanged. Thus, an output level of the amplifier 1 is unchanged. Thus, it is possible to keep the impedance constant and the oscillation in the muting control circuit 6 is prevented and a stable squelch operation is obtained.
