Tehnična rešitev varovalčnega podnožja za nožaste talilne vložke omogoča izvajanje vzdrževalnih in pregledovalnih del naprave pod napetostjo, saj ni treba omejiti dobave elektrike, ker ni treba odstraniti varovalčnih vložkov za varno izvajanje omenjenih aktivnosti.The protective foot for the knife melt inserts consists of the body of the base (1), the lids (2) of the connectors, at least one lid (3) of the fuse inserts, the connectors (4) and is functionally equipped with at least one melting insert (5). The base body (1) has two end caps (12) and at least two phase separators (11) or only two end caps (12). At the bottom of the fuse base there are opposite opposite pairs of connectors (4), through which the pairs of lid covers (2) are detachably attached. The technical solution of the fuse base for the knife melt inserts enables the maintenance and inspection of the device to be carried out under voltage, as there is no need to limit the supply of electricity, since it is not necessary to remove the fuse inserts for the safe execution of the said activities.

VAROVALČNO PODNOŽJE ZA NOŽASTE TALILNE VLOŽKESAFETY SOCKET FOR SHAFT MOLDING INSOLES
Področje tehnikeThe field of technology
Tehnična rešitev sodi v elektrotehnično industrijo in se nanaša na nizkonapetostne varovalke s talilnimi vložki z nožastimi kontakti (sistem varovalk NH).The technical solution belongs to the electrical industry and refers to low voltage fuses with fuse links with knife contacts (NH fuse system).
Varovalčno podnožje za nožaste talilne vložke je določeno za instalacijsko opremo električne naprave, na primer stikalnih plošč, elektro-energetskih razdelilnikov ali različnih oblik nizkonapetostnih razdelilnikov.The blade fuse holder is designed for the installation equipment of an electrical appliance, such as switchboards, power distribution boards, or various forms of low voltage distribution boards.
Znano stanje tehnikeThe prior art
Poznani so sistemi varovalk z nožastimi kontakti, ki se uporabljajo za nizkonapetostne električne naprave, ki uporabljajo izbirne tipe sistema varovalkKnife contact fuse systems are known to be used for low voltage electrical devices using select types of fuse system
NH.NH.
Najpogosteje se uporabljajo varovalčna podnožja za talilne vložke z nožastimi kontakti, ki se uporabljajo za priključitev stikalnih plošč hiše na 100 A, ki so montirane z varovalčnimi podnožji velikosti od 00 do 160 A, medtem ko je vložek varovalke določen kot 000 ali 00 vložek varovalke samo do 100 A.The most commonly used fuse sockets for fuse links with knife contacts are used to connect the switch panels of the house to 100 A, which are mounted with fuse sockets from 00 to 160 A, while the fuse insert is specified as 000 or 00 fuse insert only up to 100 A.
Poznana je tudi rešitev s stikalnim mehanizmom, ki vsebuje v vrsti oz. vodoravno montirane odklopnike varovalk NH velikosti od 000 do 100 A, medtem ko takšna naprava temelji na krmilnem sistemu, ki uporablja nihajni okvir (ang. lever pivot bracket).There is also a known solution with a switch mechanism which contains in series or. horizontally mounted NH circuit breakers of sizes from 000 to 100 A, while such a device is based on a lever pivot bracket control system.
Slabost omenjenih sistemov je, da lahko pri pregledu in vzdrževalnih delih pride do neželenega odklopa električnega toka, lahko pa povzročijo tudi naključen kratek stik na zgornjem delu faz. Razlog za verjetnost kratkega stika je, da nekateri izdelki nimajo ločevalne pregrade med sosednjimi priključki, ki bi preprečili pojav kratkega stika med fazami.The disadvantage of these systems is that during inspection and maintenance work, the electrical current may be unintentionally disconnected and may cause accidental short circuits at the top of the stages. The reason for the short circuit is that some products do not have a separation barrier between adjacent connectors that would prevent short circuits between phases.
Predmet izumaThe subject of the invention
Slabosti iz stanja tehnike so delno rešene z varovalčnim podnožjem za nožaste talilne vložke po tem izumu, ki obsega telo podnožja, pokrov priključkov, vsaj en pokrov talilnega vložka, priključke, ki so funkcionalno opremljeni z vsaj enim talilnim vložkom, katerega narava je označena s tem, da ima telo podnožja dva končna pokrova in vsaj dva ločilnika faz ali pa samo dva končna pokrova, medtem ko je na dnu varovalčnega podnožja za nožaste talilne vložke pokrov priključka snemljivo pričvrščen vsaj preko enega dohodnega priključka in ločeno preko vsaj enega izhodnega priključka.The disadvantages of the prior art are partially resolved by the blade guard for the knife inserts according to the invention, comprising the body of the base, the terminal cover, at least one melter cover, the connections functionally equipped with at least one melting element, the nature of which is , that the base body has two end caps and at least two phase separators, or only two end caps, while at the bottom of the blade fuse holder, the terminal cover is detachably secured through at least one incoming connector and separately through at least one output connector.
Idealno je, če je varovalčno podnožje za nožaste talilne vložke narejeno tako, da ima vodoravno notranjo razdaljo med sosednjima končnima pokrovoma ali med ločilnikoma sosednjih faz med končnim pokrovom in ločilnikom sosednje faze medsebojno prilagojene tako, da ustrezajo širini posameznih velikosti varnostnega čepa.Ideally, the blade base for the blade inserts is designed to have a horizontal internal distance between adjacent end caps or between adjacent phase separators between the end cover and adjacent phase separator so that they fit the width of the individual sizes of the safety plug.
Telo varovalčnega podnožja s svojo razporeditvijo neločljivih končnih pokrovov ali neločljivih ločilnikov faz ustvari funkcionalen prostor za pare priključkov, preko katerih so snemljivo in zanesljivo priključeni pari končnih pokrovov.The body of the fuse base, with its arrangement of inseparable end caps or inseparable phase separators, creates a functional space for couples of connectors through which detachable and securely connected pairs of end caps.
Pokrovi varnostnih čepov na vrhu varovalčnega podnožja za nožaste talilne vložke so popolnoma nameščeni na napravi in se lahko odstranijo z uporabo orodja.The safety plug caps on the top of the blade base for the fusible inserts are fully installed on the device and can be removed using a tool.
Ta tehnični izum predstavlja sistem varovalk, ki lahko s svojo obliko in strukturno zasnovo končnih pokrovov, eventualno z razporeditvijo ločilnikov faz telesa podnožja in tudi z obliko in razporeditvijo pokrovov priključkov in pokrovom talilnega vložka izvaja funkcijo za varen odklop in zaščito pred električnimi udari, tako da naprava zagotavlja zaščito pred nenamernim dotikom iz smeri dostopa do naprave ter zagotavlja, da ne pride do tveganja za nevaren stik z živimi deli naprave varovalčnega podnožja za nožaste talilne vložke.The present invention provides a fuse system which, by virtue of its shape and structural design of end caps, possibly by means of the arrangement of phase separators of the base body and also by the design and arrangement of terminal covers and the cover of the fusible cartridge, has the function of safely disconnecting and protecting against electric shock by The device provides protection against accidental contact from access to the device and ensures that there is no risk of hazardous contact with the live parts of the blade guard device.
V skladu s tehničnim izumom naprava ne samo poveča varnost pri delu, ampak pomeni tudi znižanje materialnih stroškov za proizvodnjo varovalčnega podnožja za nožaste talilne vložke in zniža stroške sestavljanja, pregledovanja in vzdrževanja.In accordance with the technical invention, the device not only increases safety at work, but also reduces the material costs for the production of a safety base for knife fusible inserts and reduces the cost of assembly, inspection and maintenance.
