81	Poletop switch automation system	US182276	1994-01-14	US5534858A	1996-07-09	Ronald B. Tinkham
A switch automation system which activates poletop power line switches in response to signals received from a remote location. An actuator piston and cylinder assembly is mounted to a power pole in alignment with existing actuator linkage. The piston and cylinder actuator assembly is translatable in response to pressurized fluid delivered through fluid lines to the cylinder. A control unit also mounted to the power pole, and in operative association with the piston and cylinder actuator assembly, houses a source of pressurized fluid. Manual operation of the poletop switches is retained by an existing operating lever. Adjustment linkage is provided for proper positioning of the actuator assembly with the existing actuator linkage. Operating signals received by the control unit result in activation of solenoids to deliver the pressurized fluid to the cylinder. Simplicity of design and linear alignment with the existing actuator linkage allow for easy installation and operation.
82	Auxiliary mechanism for imparting rotational energy to electrical components	US670742	1976-03-26	US4103120A	1978-07-25	John M. Jarosz; Roy T. Swanson
Disclosed is an auxiliary mechanism for rapidly imparting rotational energy to electrical switch components. An insulator connects an electrical switch component to an output shaft mounted for rotation in the mechanism housing. A lever arm assembly is mounted on the shaft and a link member is pivotably connected between the lever arm assembly and a first arm extending from a bellcrank member. The bellcrank member is mounted for rotation in the housing and has a second arm that is operably connected to one or more solenoids. Initially the link member and first arm are in an overcenter toggle position so that the insulator cannot be accidentally rotated. Energization of the solenoid causes rapid rotation of the insulator because the mechanical advantage of the system in such that maximum force is applied initially. Once the solenoid is de-energized, a spring connected between an extended end of the lever arm assembly and the end of the first arm returns the mechanism to its initial position with the first arm and link member in the overcenter toggle position thereby locking the output shaft and the insulator in the initial unoperated position.
83	Booster transformer switch	US3673360D	1971-03-24	US3673360A	1972-06-27	PAHL JOHN G
A switch, of pole-mounted type, adapted for connection, in an electrical power supply system, between a feed cable and a load cable; the switch, in one position, normally providing direct connection between the feed cable and the load cable, and, in another position, breaking such direct connection and establishing a by-pass connection -including a booster transformer-between the feed cable and load cable whereby to ''''boost'''' the current value in said load cable under a condition of undue voltage drop therein. The switch also provides a shunt operative to prevent the load cable from being taken completely out-of-circuit as the switch is actuated from said one position to such other position; said shunt-which includes a resistor-also serving to preload the booster transformer, with less than the full feed voltage, before the switch closes in such other position.
84	Electrical circuit interrupting device	US3602667D	1969-08-28	US3602667A	1971-08-31	REICHL ERWIN; SIEKIERA GUNTER; KINDLER HELMUT
An electrical switch including a first switch contact mounted at a point spaced in front of a support, and a second switch contact mounted on the support for movement from an on-position in which it engages the first contact to an off-position in which it is spaced to the rear of the second contact. One of the switch contacts has a quenching chamber connected to it which surrounds the space between the first and second contacts until they are separated by a sufficient distance so that arcing no longer occurs. The mounting means for the second switch contact moves the second contact first in a linear direction away from the first contact and then in a pivotal direction back toward the support.

94	AIR BREAK ELECTRICAL SWITCH HAVING A BLADE TOGGLE MECHANISM	US16000682	2018-06-05	US20180286608A1	2018-10-04	David A. Rhein
An electrical switch includes a pivotally supported blade, a toggle mechanism, and an operating mechanism. The operating mechanism is drivable in a first direction to pivot the blade about a first axis and toward a closed blade position. When pivoting toward the closed blade position, the toggle mechanism inhibits the blade from pivoting about a second axis. Upon reaching the closed blade position, continued motion of the operating mechanism in the first direction causes the toggle mechanism to pivot the blade about the second axis toward a closed contact position. In the closed contact position, the blade contacts at least one blade contact to electrically connect the blade and a first electrical terminal.
95	Drive for a switch disconnector with C O switching capacity	US13755184	2013-01-31	US08890640B2	2014-11-18	Franz-Josef Körber
Exemplary embodiments relate to a drive for a switch disconnector having C or O switching capacity and a switching pin acting as switching contact. A spindle drive is driven by an electric motor and has a spindle nut. An actuating element, which is loaded by a compression spring and is capable of pivoting about a fixed pivot point, is acted upon by the spindle nut. The actuating element for its part interacts with an actuating apparatus which actuates the switching pin.

A line-jumper apparatus typically includes a first connector, a second connector, and a housing attached to the first connector and the second connector. In a closed position, the housing provides a low-resistance current path and a high-resistance current path between the first connector and the second connector. In an open position, the housing inhibits current from flowing between the first connector and the second connector. The housing is configured so that, when the housing is transitioned from the closed position to the open position, the low-resistance current path is opened before the high-resistance current path. The housing typically includes a safety mechanism that prevents the low-resistance current path from being opened unless the high-resistance current path is closed.

100	OPERATING ARRANGEMENT FOR MECHANISM	US10139805	2002-05-03	US20030213681A9	2003-11-20	Henry W. Kowalyshen; Andrew C. Shum; John C. Opfer
An operating arrangement is provided for a mechanism or the like, e.g. an operating mechanism for a circuit interrupter for electrical power transmission and distribution systems where the operating mechanism operates on stored energy and requires a recharging operation after the stored energy is utilized to operate the circuit interrupter. The operating arrangement includes an operating member and a cooperating arrangement carried by the operating mechanism for retaining the operating member during a multi-turn charging operation. Initial operation of the operating member for one or more turns causes the operating member to be retained before any charging operation takes place. Subsequent operation of the operating member results in the charging of the operating mechanism. The operating member is then returned to an initial engagement position whereupon the operating member is released for removal from the operating mechanism. In a specific embodiment, an interlock function is also provided for the operating member, such that a key must be obtained from an associated device and inserted into the operating member before a recharging operation may begin for the operating mechanism. The key is inserted into the operating member and help captive therein before the operating member may be utilized to recharge the operating mechanism. In a specific implementation, the key is released from the associated device only when the associated device is locked in a particular operative state, e.g. a disconnect switch is locked open which releases the key for use in the operating member. Thus, while the key is held captive in the operating member during recharging operation, the disconnect switch cannot be operated.
