专利说明:

The invention relates to an overvoltage protection device for installation in an input-distribution device with a plurality of connecting terminals arranged in parallel rows providing connection of electrical conductors without removing the insulation, and can be used in the electrical industry,
The aim of the invention is to increase the reliability of the device.
FIG. 1 shows the proposed device, front view; in fig. 2 - the same, rear view; Fig. 3 shows a safety bar with a partial cut; Fig 4 is a grounding element; in fig. 5 and 6 are a grounding clip and a connecting clip.
The distribution device 1 consists of a plurality of rows of clamps 2 arranged in parallel, which have receiving devices for double connecting clamps 3. On the distribution device 1 there is a guide frame 4 consisting of two U-shaped fasteners 5 and the two side parts 6, the side parts 6 have guide grooves 7 located inside, which in their front part have inlet bevels for inserting guide safety bars 8. Both fasteners 5 are screwed to the distribution box A mounting device, the distance between the distribution device 1 and the guide frame 4 can be determined by the spacer sleeve 9. The fasteners 5 have centering bulges 10 that interact with the corresponding elements located on the input-distribution device 1 and serve for centering an overvoltage protection device. The safety bar 8 consists of a body 11 made of insulating material J and an i-shaped grounding sheet 12 made of steel 1. The body 11 of the safety bar 8 on the sides has guide ribs 13 coming into contact with the guide grooves 7 moving the safety bar 8 into the guiding frame 4, On the upper side of the U-shaped grounding sheet 12, grounding contacts 14 are stamped on the right and left

which, when the safety bar 8 is pushed in, the equalization frame 4 is inserted into the contact holes 15 and thus creates a contact between the grounding sheet and the guide frame, the metal frame 4 is connected to the earth potential. I
Guide frame design
When installing a surge protection device at the front, and when installing it at the back, it is the same. When installing an overvoltage protection device on the rear side, it is only necessary that the connecting clips 3 of the distribution switchgear be extended for connecting them to the safety bar 8.
FIG. 3, two types of the housing 11 are shown, one of which is rotated 180 ° with respect to the other, the housing 11 has cylindrical receiving sockets for arresters 16 for protection against overvoltages, and also receiving sockets in the form of grooves for. grounding elements 17; Grounding elements 17 consist of a grounding clip 18 and a spring contact sheet 19, which are connected to each other by an edge. In this case, the grounding clip 18 protrudes from the housing 11, it is fuller in fork shape, and its plane lies paratshlno the plane of the cross section of the safety bar 8. each other. This makes it possible to simply contact the grounding clip 18 with the connecting clip 3, as shown in FIGS. 5 and 6, where the position 20 indicates the contact points Between the grounding clip 18 and the connecting clip 3, the Edge connecting the grounding clip 18 and spring contact sheet 19, is twisted twice and perceives the force acting when the safety bar is installed on the grounding clip 18. The plane of the spring contact sheet 19 lies mainly in the plane | formed by the bottom side of the housing 11, so that the spring contact sheet 19 creates contact with the ring electrode of the arrester 16 for protection against overvoltage.

The bottom side of the housing 1I on the bottom of the I-shaped grounding sheet 12 is installed insulating strip 21. Thus, after inserting the safety bar 18, the leakage current flows through the supply conductor, the connecting clip 3, the grounding clip 18, the spring contact sheet 19, the discharge a ground 16 for overvoltage protection, a grounding sheet 12 with its side grounding contacts 14 and a guide frame 4, which is connected to the grounded frame of the distribution board (not along
