Title: Sven Akervall: Innovator in Surge Arrester Technology
Introduction
Sven Akervall is a notable inventor based in Ludvika, Sweden. He has made significant contributions to the field of electrical engineering, particularly in surge arrester technology. With a total of 2 patents, his work has had a meaningful impact on the industry.
Latest Patents
One of Sven Akervall's latest patents is a suspension device for line-mounted surge arresters. This device is designed for air-insulated transmission lines and includes two suspension parts that support the line arrester, allowing its longitudinal axis to deviate from the vertical line. One of the suspension parts features a disconnecting device that permits the line arrester to swing under the influence of gravity. Additionally, this part includes a damping member that counteracts the swinging motion during part of the movement. The damping member can consist of a damping plate, friction linings, or a flexible wire.
Another significant patent is the surge arrester assembly, which comprises multiple parallel-connected arrester units housed in a rack. The rack's lower and upper parts are made of aluminum bars that are part of the electric circuit. These bars are held in place by support insulators made of porcelain or polymer material. The design ensures mechanical retention of the stacks of ZnO blocks and maintains the necessary contact pressure. In the event of a short circuit, the electrical connections are arranged to direct the arc produced along the bars to arcing horns made of current-resistant material, allowing for controlled burning without environmental risk.
