摘要： A composite surge arrester assembly and method of construction protects electrical devices from voltage spikes by limiting the voltage supplied to an electric device by shorting to ground any unwanted voltages above a safe threshold. The composite surge arrester assembly forms an arrester array from an alternating arrangement of deformable conductive contact plates, and metal oxide varistor (MOV) blocks. The contact plates bend and have various types of surfaces to create uniform contact with MOV blocks. The MOV blocks are dimensioned to minimize metal mass. An epoxy impregnated fiberglass reinforcement member wraps around the arrester array at an angle between 0° to 90°, and preferably 45°, relative to the axial disposition of arrester array, while also purging air pockets therebetween. The reinforcement member dampens acoustic shock waves from high current impulses while maintaining electrical contact between MOV blocks. A polymer housing encapsulates the epoxy and fiberglass reinforced arrester array.

摘要： An arc fault detection circuit interruption (AFCI) device includes a high frequency arc noise sensor and an arc fault detection circuit for sensing a high frequency arc noise. The high frequency arc noise sensor is disposed across a hot conductor and a neutral conductor and includes a surge protection device and a surge protection circuit such that the surge protection device protects against a first voltage surge in a first range of thousands to hundreds volts and the surge protection circuit protects against a second voltage surge in a second range of hundreds to few volts. The arc fault detection circuit is coupled in series with the high frequency arc noise sensor. The arc fault detection circuit is coupled to a series combination of a trip solenoid or electromagnet and a silicone-controlled rectifier disposed across the hot conductor and the neutral conductor.

摘要： A varistor device includes a main body, a conductive area, a specific-melting-point metallic pin, and an elastic unit. The main body has a first surface, and the conductive area is located at the first surface. The specific-melting-point metallic pin has a first section and a second section. The first section and the second section are one-piece formed. The first section is fixedly disposed on the conductive area. The second section has a specific melting point such that the second section melts when a current flows between the first surface and the second section so as to expose the second section to a temperature greater than the specific melting point. The elastic unit has an end connected to the second section, and the elastic unit provides an elastic force to the second section to break the second section so as to cut off the current when the second section melts.

摘要： A method of joining an end face of a first electric component to an end face of a second electric component includes applying a first metal layer to the end face of the first electric component to form a first metallized layer and applying a second metal layer to the end face of the second electric component to form a second metallized layer. A first fusible alloy layer is applied to the first metallized layer by melting a fusible alloy and propelling the melted fusible alloy onto the first metallized layer, and a second fusible alloy layer is applied to the second metallized layer by melting a fusible alloy and propelling the melted fusible alloy to the second metallized layer. The method further includes contacting the first fusible alloy layer to the second fusible alloy layer. Next, the end faces and fusible alloy layers are heated to melt the fusible alloy layers. After heating, the end faces and fusible alloy layers are cooled to form a bond between the end faces.

摘要： A fuse assembly comprising a fuse element and a fuse cavity are formed integrally with the body of a Metal Oxide Varistor (MOV). Melting of the fuse element forms fused material which flows into the fuse cavity. The molten material electrically joins the metalization films on each side of the MOV which causes the MOV to fail shorted before the MOV can overheat and fracture from over voltage caused by excessive transient voltages. The fuse element has the current carrying capability to allow a resultant current to flow which will cause the primary circuit protection device (fuse or circuit breaker) to open. This provides protection against a violent fracture of the MOV and a MOV that can no longer function because it has opened and is undetected.
