Definitions

  • the invention relates to a high-current fuse according to the preamble of claim 1.
  • Fuses are primarily used as line protection fuses used in low voltage networks and are usually in Transformer stations, distribution points and House connection boxes arranged. You can overflow in interrupt the order of a few hundred amperes.
  • the invention is based on the idea known to design generic high-current fuses in such a way that they also generate interference signals of the type described intercept. Because such a high-current fuse Usually one due to their traditional function smaller network area, especially one that is to a single building or a complex of buildings limited, connects to the rest of the network and the Transmission of messages over the network is common also limited to such areas, it is very well positioned to foreclosure the said Areas against high-frequency interference from the rest of the network to serve.
  • the heavy current fuse according to the invention is now like this trained them in addition to interrupting Excessive suppression of high frequency signals, especially in one Frequency range between 1 MHz and 40 MHz, as in the Message transmission is mainly used. It can be designed so that it regarding electrical design and also regarding Dimensions at least as far as a known standard Power fuse means that it is such without any changes to the slot or the wider environment can replace.
  • a high-current fuse according to the invention a first embodiment (Fig. 1-3) has an approximate cuboid housing 1 made of electrically insulating Material, preferably ceramic, on the in Longitudinal opposite ends a first has electrical connection with a first End plate 2, a contact knife on the outside 3 carries and a second electrical connection with a second end plate 4, which on the outside Contact knife 5 carries. Which close the housing 1 End plates 2, 4 exist z.
  • the interior of the housing is made of a partition plate 6 electrically conductive material, e.g. B. Aluminum in two Longitudinal successive sections divided.
  • the slightly longer first section between the End plate 2 of the first electrical connection and the partition plate 6, contains a fuse element, the the end plate 2 with the partition plate 6 electrically connects in a leading way. It consists of three in a row consecutively arranged in parallel Silver coat bands 7 and is so in a known manner designed that in the event of overcurrent according to a standardized Characteristic curve according to a current dependent Response time melts and the current is interrupted.
  • the housing In between the partition plate 6 and the end plate 4 of the second electrical connection lying section of the A choke is arranged inside the housing. It consists of a cylindrical winding 8 which the partition plate 6 with the end plate 4 electrically connects and one continuous core made of a ferromagnetic, preferably electrically insulating material, in particular ferrite, the than lying in the axis of the winding 8, surrounded by it massive round rod 9 is formed.
  • the inductance of the Choke is chosen so that its impedance at frequencies on the order of magnitude of the network frequency, i.e. approx. 50 Hz is negligibly small, at high frequencies of 1 MHz up to 40 MHz, however, very large.
  • the heavy current fuse can with respect to their Dimensions of sizes 1-3 of standard DIN 432620 correspond and z. B. be designed for 400 V and 400 A. You can always replace conventional fuses that comply with this standard.
  • a second embodiment (Fig. 4, 5) of the Distinguishes high-current fuse according to the invention differs from the first only in that the winding 8 is a bit smaller and the core next to an in the axis of the same arranged rod 9 also a Has winding 8 surrounding shell, which consists of two half-shells 10a, b connected to the head ends of the rod 9 consists of a central air gap 11th are separated.
  • the shell has two diametrically opposed to each other opposite, extending over their entire length sector-shaped openings 12a, b, through which the winding 8 with the partition plate 6 and the end plate 4 is electrically connected.
  • a third embodiment (Fig. 6-8) also corresponds largely the first, but again extends as massive round rod 9 formed core essentially over the entire length of the housing 1 and extends from the End plate 2 of the first electrical connection to to the end plate 4 of the second electrical connection.
  • the three silver sheathed strips 7 of the fuse element are around the Bar 9 arranged around.
  • the embodiment stands out through particularly good mechanical stability.
  • a fourth embodiment shows a different structure (Fig. 9-11) of the invention Heavy current fuse.
  • the core here is again as Rod 9 formed, which is surrounded by the winding 8.
  • both are rectangular in cross-section cuboid and the rod 9 is hollow, it has a continuous central bushing in the longitudinal direction, in which the fuse element is arranged, which is made here a single silver jacket band 7.
  • the winding 8 is from the end plate 2 of the first electrical Connection through an insulation layer 13 and that Silver jacket tape 7 from the end plate 4 of the second electrical connection through an insulation layer 14 Cut.
  • the silver jacket band 7 closes through an opening in the first insulation layer 13 to the first end plate 2 on. Its opposite end is over one on the intermediate plate 15 resting on second insulation layer 14 connected to a return wire 16 which is in a groove on the outside of the rod 9 against the Silver coat band 7 to the next of the first end plate 2 lying end of the winding 8 runs back. That this opposite end of the winding 8 is through an opening in the second insulation layer 14 finally with the End plate 4 connected.
  • the current path runs from the end plate 2 through the silver jacket 7, the Intermediate plate 15, back through the return wire 16 and after a new reversal of direction by the winding 8 to the end plate 4.
  • This embodiment is particularly space-saving, in particular, it can be very short. You can therefore in the Dimensions of size 00-3 of standard DIN 43620 are manufactured and always replaced by conventional ones Heavy current fuses occur that meet this standard correspond.
  • a fifth embodiment of the invention Heavy current fuse corresponds in its basic structure of the fourth embodiment, but is the winding 8 is arranged next to the fuse element, the between the contact knife 3 of the first electrical Connection and an intermediate plate 15 is arranged and again consists of three parallel silver jacket bands 7.
  • the intermediate plate 15 is by means of a return wire 16 with the first electrical connection adjacent end of the winding 8 connected, the opposite end to the end plate 4 of the second electrical connection. Between the latter and the intermediate plate 15 is an insulation layer 14.
  • Die Winding 8 surrounds a core of one Insulation layer is surrounded. It can in turn be massive round rod 9 may be formed or from several parallel bars exist.
  • the current path runs from the contact knife 3 of the first electrical connection via the silver jacket tapes 7 to Intermediate plate 15 and further via the return wire 16, through the winding 8 and the end plate 4 to Contact knife 5 of the second electrical connection.
  • the Heavy current fuse according to the invention (Fig. 15-17) with one arranged between the contact blades 3, 5 Winding 8 and an adjacent one, formed as a silver sheath band 7 fuse element constructed like the invention Heavy current fuse according to the fifth Embodiment.
  • the contact knife 3 of the first electrical connections are closed by the end plate 2 the same, which over the fuse element with a Intermediate plate 15 is connected, which is spaced apart the end plate 4 of the second electrical connection is arranged.
  • the intermediate plate 15 is over the Return wire 16 with that of the connection plate 2 of the first electrical connection first end of Winding 8 connected, the opposite end to the End plate 4 of the second electrical connection bumps, which in turn carries the same contact knife 5.
  • the winding 8 in turn surrounds a core that is considered to be solid Round rod 9 formed and surrounded by insulation is, which also forms an insulation layer 13, the the winding 8 and the return wire 16 from the End plate 2 of the first electrical connection separates and an insulation layer 14 through which the Winding 8 with the end plate 4 of the second electrical connection is connected.
