Title: Disconnector with resistor
Inventor: KOYAMA MITSUTOSHI
IPC: H01H33/16
Filed: 1994-03-18
Abstract: PURPOSE:To judge functional quality of a resistor from the outside of a disconnector without stop of operation of a switch device by arranging a capacitance type electrode in part of a sealed container faced to a resistor shield, and further arranging a DC voltage generator and an ammeter on the outside of the sealed container. CONSTITUTION:Capacitance of several pF order exists between resistor shields 16, 17 and conductive plates 20, 21. Capacitance C of the resistor shields 16, 17 and resistance R of the resistor 18 exist in parallel to form a series-parallel circuit. A switch is connected to one end of the capacitance and an ammeter 27 is connected to one end of a DC power source 26. When the switch is turned off, a charge introduced into the capacitance is discharged by a time constant dependent on the resistance through the resistor 18. When the resistance of the resistor 18 varies, a current wave form varies. Since the wave form is distinctly different from that in a terminal resistor, the abnormality of the resistor 18 can be detected.
