    Abstract: A power distribution system element formed via an additive manufacturing technique, such as applying a conductive material to a memory metal substrate, are discussed herein. In operation (e.g. in response to delivering current through the distribution system), the memory metal contracts while the conductive material expands. The result is distribution system element having reduced thermal expansion, which can be net zero coefficient of thermal expansion.

  • Patent number: 8953306
    Abstract: A load center featuring a two-piece dielectric barrier that securely retains a plug-on neutral rail and methods of assembling the same. The barrier includes a shield and a base having a protrusion that cooperates with fingers of the shield to securely retain the conductor in the load center. The shield is installed over the base and rests on hooks protruding from the base. This creates a distance between the protrusion and the fingers to allow the conductor to be inserted through a gap between the fingers along the conductor's skinny edge. The conductor rotates 90 degrees until it rests on the protrusion. The base and shield are snapped together, causing the hooks of the base to attach to the shield. At the same time, the fingers of the base move downward to rest against the conductor so that it is sandwiched securely between the protrusion and the fingers.

  • Patent number: 8669472
    Abstract: Electrical busway assemblies and methods and devices for applying compressive forces to a busbar stack in an electrical busway assembly are disclosed herein. Electrical busway assemblies for distributing electricity are presented. The busway assembly includes a stack of electrically conductive busbars with one or more duct sides each disposed on a respective side of the busbar stack. Optionally, a duct top and duct bottom can be placed on the stack top and stack bottom, respectively. A surge clamp engages the stack top or stack bottom. A bolt attaches the surge clamp to each duct side. A compression nut threadably engages each bolt. Rotation of a bolt moves the corresponding compression nut, which acts to move the surge clamp along a path that is oblique with the path of the compression nut. The surge clamp, when moved by the compression nut(s), acts to apply a compressive force to the busbar stack.

  • Publication number: 20130306344
    Abstract: There is provided an electrically conductive path device which can prevent radiation noise. An electrically conductive path device includes three bus bars electrically connecting a motor unit to an inverter unit, capacitance portions creating stray capacitance and an insulator. In terms of the electrically conductive path device, switching operation of a semiconductor switch located inside an inverter of the inverter unit creates change in voltage which is transmitted to the bus bar corresponding to a path from the inverter to the motor. At that time, the change in voltage is not transmitted further to the motor but is transmitted to the bus bar corresponding to a path from the motor to the inverter via the capacitance portion formed between the facing portions, i.e. via the stray capacitance.
