摘要： A vacuum-type electrical switching apparatus (10) for high voltage electrical power. A vacuum pressure condition in a vacuum pressure space (21) surrounding electrical contact points (18) is monitored and movement of the contact points between open and closed positions is automatically prevented when the pressure exceeds a predetermined threshold in order to avoid destructive arcing between the points. A sensor (32) provides a vacuum signal (34) responsive to the vacuum pressure condition. A controller (36) automatically inhibits movements of the contact points when the vacuum signal indicates that the vacuum has degraded. A contactor (38) may be placed in series with power supply (28) and a solenoid (24) used to move the contact points, with the contactor being automatically opened by the controller in response to the degraded vacuum condition. An electromechanical opening inhibitor (74) may be energized by the controller to mechanically prevent the contact points from being moved in response to the degraded vacuum condition.

摘要： A vacuum circuit interrupter is taught which utilizes the vapor deposition shields thereof and the existing high voltage electrical source or network which is controlled by the circuit interrupter to produce a cold cathode detector for determining the quality or amount of vacuum within the vacuum circuit interrupter. The central shield support ring which protrudes through the insulating casing of the circuit interrupter is utilized to supply electrical current to a current measuring device and to return one of the shields of the cold cathode detector to the common terminal of the aforementioned voltage source.

摘要： An apparatus for protecting a vacuum interrupter type on-line tap changer in which a cross current flows between taps through a current limiting resistor for a predetermined time by shorting selected taps therebetween at the time of tap changing operations. Vacuum interrupters are employed as current switching elements. A dial switch selects the position of the tap of the tap changer. A limit switch closes only at a predetermined position of the dial switch during tap changing operations. Thus, a cross current between the taps or a load current flowing for a long time due to a drop in the degree of vacuum of the vacuum interrupters is detected, thereby preventing burn-out of the current limiting resistor and damage to contacts of a disconnecting switch due to interruption of the current.

摘要： A method is disclosed for detecting a leak in any one of the vacuum interrupters of a vacuum-type circuit breaker that comprises a plurality of vacuum interrupters disposed within a housing filled with pressurized insulating gas. The method comprises: (a) opening the circuit breaker and effectively disconnecting the closing mechanism of the breaker from the operating rod of the breaker so as to effectively preclude the closing mechanism from exerting a closing force on the operating rod, (b) measuring the net force on the operating rod after (a) has been performed, and (c) comparing the measured net force to a standard value corresponding to the force on the operating rod when the interrupters are intact and the insulating gas is at the same pressure as when the net force was measured.

摘要： Method and apparatus for measuring pressure in vacuum interrupters in which electrical connection to the metallic shield provided within the interrupter is not available. Transverse electrostatic and electromagnetic fields are generated within the interior of the vacuum interrupter so as to cause stray electrons within the interior space of the vacuum interrupter to travel in cycloidal or elliptical paths. The tortuous route assumed by the electrons greatly enhances the propability of an ionizing collision The pressure measurements are taken by measuring the number of positive ions collected at the negative electrode and comparing the measurement to a calibration chart on which pressure versus current has been plotted. The measurements may be taken by measuring the time required to charge a capacitor whose charging rate is determined by the vacuum interrupter resistance which is the unknown quantity being measured.
