Publication number: 20140218834Abstract: The invention relates to a surge arrester comprising at least two mutually opposite fittings 3, at least one varistor block 5, which is arranged between the fittings 3, and at least one reinforcing element 7 in the form of a closed loop, which holds the fittings 3 and the varistor block 5 against one another under pressure. According to the invention, the reinforcing element 7 is held on each of the two fittings 3 in each case on at least two sides of the fitting 3. In this way, four sections 7a, 7b, 7c and 7d of the reinforcing element 7 are formed which extend from one fitting 3 to the other fitting 3 and ensure the mechanical stability of the surge arrester.Type: ApplicationFiled: January 20, 2012Publication date: August 7, 2014Inventors: Hartmut Klaube, Christoph Koch

Patent number: 8446703Abstract: The invention relates to a surge arrester having at least one varistor block 1, one end fitting 3, one reinforcing element 9 which holds the varistor block 1 firmly on the end fitting 3 with a tensile load, and at least one anchoring element 27 which holds the reinforcing element 9 firmly on the end fitting 3 with a tensile load wherein the anchoring element 27 has at least one edge 29 which cuts into the reinforcing element 9. The anchoring element 27 is preferably a cutting-ring screw union.Type: GrantFiled: November 26, 2007Date of Patent: May 21, 2013Assignee: Tridelta Uberspannungsableiter GmbHInventors: Hartmut Klaube, Hubert Lauritsch

Patent number: 8305184Abstract: Surge arrester with a module 1, 3, 9, 25, which comprises a stack of varistor blocks 1, two end armatures, between which the stack of varistor blocks 1 is held, a plurality of reinforcing elements 9, which extend between the end armatures 3 and are fixed to said end armatures, the reinforcing elements 9 surrounding the stack of varistor blocks, and at least one stabilizing disc 25, which is arranged between two varistor blocks 1 in the stack and guides the at least one reinforcing element 9, and with an outer housing 5 with screens, in which outer housing the module is at least partially accommodated. In the case of the surge arrester according to the invention, the outer housing is designed in such a way that the module is accommodated without any gas, liquid or volumes or cavities therebetween. Furthermore, each of the stabilizing discs 25 is arranged in the region of one of the screens 7.Type: GrantFiled: September 4, 2008Date of Patent: November 6, 2012Assignee: Tridelta Uberspannungsableiter GmbHInventors: Hartmut Klaube, Hubert Lauritsche

Patent number: 8064181Abstract: The invention relates to a surge arrester having at least one varistor block; two end fittings; one reinforcing element which holds the varistor block under tension at the end fittings and at least one anchoring element, which holds the reinforcing element in a hole through at least one of the end fittings. The reinforcing element is preferable a wedge which splits the reinforcing element and braces with the outer walls of the through-hole. Alternatively, two or more glass-fiber-reinforced reinforcing elements are held in a through-hole, and a wedge between these reinforcing elements ensures that the reinforcing elements are held with a force fit in the end fitting in the area of the through-hole.Type: GrantFiled: December 11, 2006Date of Patent: November 22, 2011Assignee: Tridelta Uberspannungsableiter GmbHInventor: Hartmut Klaube

Patent number: 8009402Abstract: The invention relates to a surge arrester having a cage design, and to a method for its production. According to the invention, during extrusion-coating or encapsulation of a module comprising two end fittings (3) and a plurality of varistor blocks (1) and at least one reinforcing element (9) in order to form the outer housing (5), first through-holes (11) for the reinforcing element (9) thereof are sealed with silicone. For this purpose, second through-holes (15) are provided in the end fittings (3), through which the silicone runs during casting or spraying, and enters the through-holes (11) from the outside, in order in this way to seal them against water and moisture.Type: GrantFiled: December 22, 2006Date of Patent: August 30, 2011Assignee: Tridelta Uberspannungsableiter GmbHInventor: Hartmut Klaube

Publication number: 20090225487Abstract: The invention relates to a surge arrester having at least one varistor block 1; two end fittings 3; one reinforcing element 9 which holds the varistor block 1 under tension at the end fittings 3 and at least one anchoring element 13, which holds the reinforcing element 9 in a hole 11 through at least one of the end fittings 3. The reinforcing element 13 is preferable a wedge which splits the reinforcing element 9 and braces with the outer walls of the through-hole 11. Alternatively, two or more glass-fibre-reinforced reinforcing elements are held in a through-hole 11, and a wedge between these reinforcing elements ensures that the reinforcing elements are held with a force fit in the end fitting in the area of the through-hole 11.Type: ApplicationFiled: December 11, 2006Publication date: September 10, 2009Applicant: TRIDELTA UBERSPANNUNGSABLIETER GMBHInventor: Hartmut Klaube
