Definitions
- the invention relates to a separate device to protect electrical systems and especially the devices connected therein, as well as their users, from a risk from brief overvoltages occurring in the line network.
- shock wave or traveling wave that arises when the lightning strikes the overhead line may propagate along the lines to the house installation and can break through and destroy insulation there and cause considerable damage.
- Abieiter has already been developed - as for the protection of telecommunication lines and devices - for AC networks with a higher operating voltage, by means of which the overvoltages in the area of the house installation can be reduced to a non-hazardous level.
- an arrangement has now proven and prevailed for this purpose, which consists of the parallel connection of a gas discharge line acting as a surge arrester and a varistor with a current-dependent resistance characteristic and as such is connected between the lines to be protected and an earth line. With this arrangement, the much more frequent low-energy surge peaks can be reduced to such an extent that the ignition voltage of the arrester is not reached at all.
- the leakage current through the varistor increases and with it the voltage drop across the protective combination.
- the arrester is ignited and in turn now protects the varistor and the connected devices.
- the main fuse upstream of the protective device or the consumer circuits of the house installation system may fail and must be replaced.
- the object of the invention is to provide a less complex and more practical option for house installation systems instead of, if at all, built-in overvoltage protection device in the house junction box after the main fuses after the main fuses, in order to subsequently make the circuits of the existing system effective in a simple manner to protect against the risk of overvoltages.
- the invention forms such an overvoltage protection device according to the plug system used in the perm of an adapter plug or adapter and according to the preamble of claim 1 to the effect that the switching elements of the protective combination of a gas-filled arrester and a zinc oxide arranged in the housing of such a plug connector.
- Varistor are directly connected to the (device-side) plug contact sockets and are in direct connection with the (mains-side) connector pins on the one hand and on the other hand via a fuse element included in the respective housing shape.
- the protective combination is switched by the phase conductor and the neutral conductor against the grounded protective conductor.
- the device simply plugged in between the mains connection and the consumer, due to its large discharge capacity, extremely quickly limits both the low-energy voltage peaks and the high-energy overvoltages due to atmospheric discharges.
- the fuse connected upstream of the protective combination on the mains connection side may cause the mains voltage to be switched off when the arrester has ignited. This measure prevents that after Decay of the overvoltage under the influence of the mains voltage still present and, depending on the network impedance at the respective place of use, a so-called pole current can flow through the conductor and prevent it from being safely extinguished.
- the housing of the overvoltage protection device which is divided in the longitudinal direction, is composed of two uniform plastic hollow shells which are penetrated in their interior for mechanical connection with one another transversely by the molded-on parts of the holder for the fuse element accessible from the outside.
- this configuration allows the two half-shells of the insulating material housing to be coupled to one another in a suitable manner and ready for use; on the other hand, this results in the possibility of being able to replace the fuse which is accommodated together with the other switching elements within the housing in the event of a defect from the outside.
- the surge protection devices are independent elements in each application, which are simple and without modification or addition to the existing facilities of a house installation system against the corresponding elements in unprotected Have the version, such as normal earthed plug or multiple adapter etc. replaced.
- the protective elements according to the invention it is advantageously achieved that the dangerous overvoltages entering the consumer power network from outside through load changes or atmospheric discharges within these protective elements between the relevant line arm compensate for and reduce them In the immediate vicinity of the place of use of these protective elements, there is no longer any risk of arcing and inadvertent triggering of the contact protection elements of a system.
- the device according to the invention ensures sufficient intrinsic safety even under extreme loads due to the built-in fuse, in order not to let the ignited surge arrester continue to burn due to the follow-up current.
- the attached drawing shows a typical embodiment example of a multiple plug connector equipped with the surge protection device according to the invention for inserting two 2-pole flat plugs into a protective contact socket.
- the two pairs of sockets 1 are inside the insulating housing 2 at their connection points of the surge arrester 3 and the zinc oxide varistor 4 in Parallel connection bridged.
- One of these connection points is directly connected to one of the plug pins 5, for example riveted, while the electrical connection from the other pair of sockets 1, as indicated in the drawing only by the dividing line "x", is via.
- Fuse 6 runs to the other connector pin 5.

Abstract
Afin de proteger les appareils electromenagers ou leurs utilisateurs contre les surtensions dangereuses provoquees par des variations de charge dans le reseau ou par des decharges atmospheriques (foudre), un element de derivation (3) rempli de gaz et un varistor a l'oxyde de zinc (4) sont disposes dans le boitier (2) de la fiche de prise de courant en forme de fiche intermediaire ou d'adaptateur, entre les alveoles (1) de la fiche du cote appareil, et montes en parallele, afin de court-circuiter les bornes de connexion ou relies entre celles-ci et le conducteur de terre. Cet ensemble de protection (3, 4) est connecte, d'une part directement, d'autre part par l'intermediaire d'un fusible (6) aux broches (5) de connexion au reseau, afin d'empecher par la suppression des surtensions un claquage dans le reseau et par la suite le declenchement du disjoncteur de protection a courant de defaut de l'installation.
