    Abstract: A plurality of heat-conducting fins disposed on various types of electrical conductors both insulated and uninsulated, and for both high- and low-voltage applications such as in bus bars, disconnect and knife switches, and circuit breakers. Each of said fins includes a central opening which is slightly smaller in one dimension than the conductor on which the fins are assembled and therefore must be distorted somewhat during assembly on the conductor. The distortion in each fin develops a torsional stress in the fin which causes it to tightly grasp the conductor. In certain high-voltage applications, the fin may be insulated or bent over to reduce the effective radial size of the fins in the overall conductor assembly without reducing its surface area and ability to convect heat.

    Abstract: An improved power-conductor assembly is provided using a plurality of generally-rectangular bars, spaced laterally apart, and extending generally in parallel relationship, with the number of the bars, and the material thereof, dependent upon the current-rating capability of the equipment, for example, 1200amperes, 2,000-amperes, or 3,000-amperes, for example. Improved insulating means is provided for the power-conductor assembly including pairs of first and second post-type standoff insulating insulators, such as post-type porcelain insulators, preferably utilized in pairs for supporting the power-conductor assembly away from ground potential, or away from other energized powerconductor assembly equipment which is at a different voltage level. For supporting purposes, it is desirable to utilize pairs of first and second laterally-spaced post-type standoff insulators to reduce the cost and quantity of insulating material required, having preferably mounting bolts cast into the ends of the posttype insulators, such as formed of porcelain, for example, to support suitable hardware, such as metallic channel members, for example, to accommodate the power-concuctor assemblies.

    Abstract: The primary disconnecting contacts of a metal-clad switchgear unit has at least one, and preferably two, heat pipes incorporated in the structure thereof. The use of one or more heat pipes conducts the heat generated adjacent the point of contact separations, and removes it to a remote area, at which heat sinks may be readily provided to more easily dissipate the heat generated at the separable contact structure. The advantage results that a cheaper material, such as aluminum, of small cross-sectional area, may be utilized instead of a solid copper disconnecting contact structure or higher currents may be carried where large conductors are restricted by available space. Suitable finned structures may be associated with the one or more heat pipes to serve as heat-sink structures. Also, where power conductors pass through locations, where radial heat flow is impeded, a heat pipe may advantageously be incorporated therein.

    Abstract: A rotary switch with separable stationary and movable contacts and having a shaft which is rotatable to actuate the movement of the movable contacts between first and second operating positions. A spring return mechanism biases the shaft toward a first angular position corresponding to the first operating position of the movable contacts. A lever arm is mounted on the shaft for movement therewith and carries a magnetic armature. A stationary magnetic structure is disposed adjacent to the shaft and includes a permanent magnet member. When the shaft is rotated to a second angular position which corresponds to the second operating position, the magnetic armature engages or seats against the stationary magnetic structure and the magnetic flux from the permanent magnet member passes through the armature to magnetically latch the shaft in the second angular position against the influence of the spring return mechanism. An electromagnetic coil or winding is disposed on the stationary magnetic structure and is energizable to provide a magnetic flux which opposes the magnetic flux which passes through the armature from the permanent magnet member to thereby release the armature and the shaft which is then actuated to the first angular position by the spring return mechanism.
