Overvoltage protection system and overvoltage protection element for an overvoltage protection system

Abstract: An overvoltage protection system with an overvoltage protection element (1) and an ignition aid which triggers the overvoltage protection element (1), the overvoltage protection element (1) having two main electrodes (2, 3) and an air-breakdown spark gap (4) which acts between the main electrodes (2, 3). An overvoltage protection system having a relatively small and also largely constant operating voltage is implemented by there being an ignition circuit (5) with an ignition voltage output (6) as the ignition aid, the overvoltage protection element (1) having an ignition spark gap (7) which acts between the main electrodes (2, 3) with at least one ignition electrode (8) and the ignition electrode (8) being connected to the ignition voltage output (6) of the ignition circuit (5).

Spring force print clamp, has chamfers with side wall sections limiting guide slots, where chamfers form even positioning surfaces for tool towards guide slots that are molded into broad side panels

Abstract: The clamp has a spring leg provided at an interior of a metal cage from a region of a roller's side (4) to a clamping side (7) in a converging manner. The region lies towards the clamping side. The spring leg is clamped with a clamping force directed against the clamping side. Guide slots (10) are molded into broad side panels (1) of the metal cage, where slots lie opposite to each other and opened at the roller's side. Chamfers (13) include side wall sections that limit the guide slots. The chamfers form even positioning surfaces (14) for a tool e.g. screwdriver blade, towards the slots.

Sichere photovoltaik-anlage

Abstract: Die Erfindung betrifft eine Photovoltaik-Anlage (1) mit zumindest einem Strang (20) aus Solarmodulen (30) und einem System (12) zum einzelnen Freischalten der Solarmodule und zum sicheren erstmaligen Anschalten oder Wiederanschalten der freigeschalteten Solarmodule an den Strang. Die Solaranschlussdosen (12) sind zumindest teilweise "intelligent" ausgebildet und weisen eine Sicherheitsschaltung (13) auf, die einen Betriebszustand und einen Sicherheitszustand definiert. Die Solaranschlussdosen werden durch das Einpragen eines Startstroms (76) vom Sicherheitszustand in den Betriebszustand umgeschaltet, d.h. aktiviert.

Communication entities for communication via a bus-oriented communications network

Abstract: The invention relates to a communications entity for communications via a bus-oriented communications network with a control device ( 101 ) that is constructed to communicate via the communications network in response to a selection signal according to a first communications bus sub-system or according to a second communications bus sub-system, and a selection device ( 103 ) for generating the selection signal as a function of an operating mode of the communications entity, in order to select the first communications bus sub-system or the second communications bus sub-system

Connection and junction box for a solar module

Abstract: A connection and junction box for a photovoltaic solar module having flexible flat conductor band protruding from the surface of the solar module, wherein the connection and junction box has an insertion mouth at its side facing the solar module in mounted state, for at least one flexible flat conductor band of the solar module, and comprises a housing for attaching on the solar module, and a connection device for the flexible flat conductor band, positioned in the housing, the connection device has an electrical contact clamp, which is closed when putting the box on the solar module, and thereby catches and contacts the flat conductor band.
