Embodiment Construction

[0015] figure 1 Indicates an assembly consisting essentially of a tubular high-voltage insulator 1 and a surge arrester 2 mounted on a circuit board 3 . The high-voltage insulator 1 has an electrical component 4 inside it, and is a high-voltage insulating bushing for guiding electrical conductors provided with capacitors for controlling the electric field.

[0016] The high-voltage insulator 1 of the assembly has a housing 11 consisting of a mounting body 12 designed as a glass-fibre-reinforced plastic tube and an elastomeric rain shield 13 which is placed over the plastic tube. The rain shield 13 is dimensioned such that the high voltage insulator 1 is designed for a voltage level of 145 kV. In addition, the housing 11 is further provided with a metal bottom 14 and a metal head 15 .

[0017] The surge arrester 2 consists of a plurality of columns 21 consisting of resistive elements 22 and is connected to the metal base 14 via a lower electrical connection element 23 and to...

Abstract

The invention relates to a novel module that comprises an insulator (1) that forms an integral part with a surge arrester (2) composed of resistor elements. The insulator (1) is configured as a composite part with a solid body (12), for example a glass-fiber reinforced plastic tube, and an elastomer sleeve (13) molded thereonto, for example a protection, and the surge arrester (2) is embedded into the molded-on elastomer sleeve (13).

Description

technical field [0001] The invention relates to the field of basic electrical components and can be applied to the structural design of insulators which are combined with surge arresters to form a component. Background technique [0002] In the field of power transmission and distribution, ZnO-based metal oxide resistors with strongly nonlinear characteristics have recently been used as surge arresters. The small structural volume of this arrester opens up the possibility of combining it in insulating bushings, cable glands and also inside transformers and switchgear (“Bulletin SEV / VSE ", 7 / 98, pp. 13-20). In a known design for assembling such arresters in insulating bushings of high-voltage conductors, the resistive elements of the arresters are stacked one by one to form a column, arranged concentrically inside the insulator around its axis and thus also concentrically Here the high voltage electrical conductors are arranged. The insulator consists of a hollow housing p...
