The invention relates to an encapsulated surge protection device capable of carrying lightning currents and limiting follow currents and comprising at least one spark gap, which has in each case at least two main electrodes and one auxiliary electrode, which is connected to a starting device for triggering in the event of transient surges. The invention provides a second starting device which is independent of the first starting device and which can activate the spark gap without the need for the presence of surges or pulse currents on the basis of the presence of a minimum voltage between the main electrodes of the spark gap.

Encapsulated surge protection device capable of carrying lightning currents and limiting follow currents and comprising at least one spark gap

A compact arrangement for multipole, surge-protected surge arresters, including internally wired, encapsulated series gaps arranged essentially in parallel in a housing. The series gaps have opposite-lying, projecting contact surfaces connected to outer terminals and inner contact bars or bridges. An electronic control or trigger circuit is located on a wiring support. The housing includes dividing walls and has a trough shape, the resulting housing chambers accommodating the gaps and terminals. An insulating plate with openings into which spring contact elements are introduced is provided on the housing trough which opens upwards. Located above the insulating plate is the wiring. The spring contact elements create the electrical connection between contact points on the underside of the wiring support and the cover of one of the series gaps, respectively. Further, an encapsulated surge protector includes a series gap arrangement with two metallic main electrodes lying coaxially to each other and at least partially overlapping each other and having connections in opposite directions. The main electrodes form an arc chamber in conjunction with at least one insulation part. At least one of the main electrodes has an inner expansion chamber and a trigger electrode extending preferably radially or axially rotationally symmetrically is provided at least in the area of an outer insulation part.
