Voltage surge arrester and current protection magazine for LSA-Plus (substation control and protection system - plus) isolating strips, for telecommunications technology, which are fitted with connecting contacts which are free of solder, screws and insulation-stripping and have a polytropic airgap, that is to say, LSA-Plus contacts

摘要

The subject-matter of the invention is a voltage surge arrester and current protection magazine (1) - ÜVA magazine for short -especially for LSA-Plus isolating strips, for telecommunications technology, which are fitted with connecting contacts which are free of solder, screws and insulation stripping and have a polytropic airgap that is to say, LSA-Plus contacts, in which magazine a current protection device (2a, 2b) and/or a voltage surge duplicated arrester (3a, 3b) in the ÜVA magazine (1) can be clamped into a holder (2, 3), by means of contact springs, for each line path (a-a', b-b') with an input line (a or b respectively) and output line (a' or b' respectively), in each case one contact track (4a, 4a' or 4b, 4b' respectively) is provided as an isolating element (4) on the underneath (1c) of the ÜVA magazine (1), which is constructed in a plug-in manner, per line path (a-a' or b-b' respectively) on the front side and rear side (1a, 1b), which contact track is connected to in each case one pole (2c, 2c') of the current protection device (2a or 2b respectively), the poles (2c') of the current protection devices (2a, 2b) are connected to in each case one pole (3c) of the voltage surge duplicated arrester (3a, 3b), and the centre contacts (3d) of the voltage surge duplicated arrester (3a, 3b) are connected to a common earthing rail (8) which is connected to two earthing pick-off terminals (5).
