Abstract:
A surge arrester comprising:a cylindrically symmetrical housing which can be grounded, which is designed as a bottle and which has a housing portion in the form of a bottle neck and a conically expanding housing portion connecting the bottle neck to a wider cylindrical housing portion; an active part which is arranged in the wide cylindrical housing portion, which is aligned along an axis of symmetry and has two connection fittings, at least one varistor element arranged between the two connection fittings and at least one loop which is mounted with its ends on the two connection fittings and which acts on the connection fittings and the at least one varistor element to form a contact force; a plug connection member, which can be brought to a high-voltage potential and which includes a plug contact arranged outside of the cylindrically symmetrical housing and a cylindrically symmetrical electrical conductor, which conductor passes through the bottle neck and the conically expanding housing portion and connects the plug contact to one of the two connection fittings within the wide cylindrical housing portion; and a dielectric sleeve, which surrounds the active part and the cylindrically symmetrical electrical conductor and insulates the active part and the cylindrically symmetrical electrical conductor from the cylindrically symmetrical housing.
