Esillä olevan keksinnön kohteena on kytkinlaitekaapin tai muun sähkövarustetilan oven lukkolaite.The present invention relates to a door locking device for a switch cabinet or other electrical equipment compartment.

Kun koteloiduissa kytkinlaitteissa esiintyy avoimia valokaaria, voi syntyä suuria paineen nousuja. On esimerkiksi mitattu 3-1* tonnin/m paineita sellaisen kytkinlaitekaapin ovessa, jossa 40 kA:n valokaari on palanut 1 sekunnin ajan. Kaapin oven ja sen lukkolaitteen on oltava mekaanisesti niin lujat, etteivät ne anna myöten näille suurille paineille. Oven ympärille ei myöskään saa muodostua niin suuria halkeamia, että ulosvirtaavat kuumat kaasut voivat vahingoittaa käyttöhenkilökuntaa.When there are open arcs in encapsulated switchgear, large pressure rises can occur. For example, pressures of 3-1 * tons / m have been measured in the door of a switch cabinet where a 40 kA arc has burned for 1 second. The cabinet door and its locking device must be mechanically strong enough to withstand these high pressures. Also, cracks must not form so large around the door that hot gases escaping can injure the operating personnel.

Ruotsalaisessa patenttijulkaisussa 356 785 on kuvattu rakenne, jossa oven molemmille puolille on järjestetty pystysuorat kulmaraudat, joita vasten ovi ruuvataan kiinni ruuveilla. Tämän rakenteen epäkohtana on kuitenkin se, että oven sulkeminen on pikkutarkkaa ja aikaavievää työtä, josta seuraa myös, että on olemassa vaara, ettei ruuveja kiinnitetä kunnolla, esimerkiksi työtä tekevän henkilön ajanpuutteen tai unohtamisen takia, jolloin seurauksena on puutteellinen henkilöturvallisuus.Swedish patent publication 356 785 describes a structure in which vertical angle irons are arranged on both sides of the door, against which the door is screwed with screws. However, the disadvantage of this structure is that closing the door is a small and time-consuming job, which also means that there is a risk that the screws will not be fastened properly, for example due to lack of time or forgetting by the person working, resulting in poor personal safety.

Esillä olevan keksinnön tarkoituksena on saada aikaan kytkinlaitekaap-pien ja sentapaisten ovien lukkolaite, jonka käyttö on yksinkertaisempi ja joka antaa paremman henkilöturvallisuuden kuin aikaisemmin tunnetut rakenteet. Tämä saadaan aikaan patenttivaatimuksen 1 tunnus-merkkiosassa ilmoitetuilla toimenpiteillä.The object of the present invention is to provide a locking device for switch cabinets and the like, which is simpler to use and which provides better personal safety than previously known structures. This is achieved by the measures indicated in the characterizing part of claim 1.

Eräs keksinnön suoritusesimerkki esitetään oheisessa piirustuksessa. Kuvio 1 esittää edestä katsottuna kytkinlaitekaappia lukkolaitteineen, jonka rakenne käy lähemmin selville kuviosta 2 ja 3> jotka esittävät leikkauksia kuvion 1 viivoja A-A ja vastaavasti B-.B pitkin.An embodiment of the invention is shown in the accompanying drawing. Fig. 1 shows a front view of a switch cabinet with locking devices, the structure of which will be seen in more detail in Figs.

Esitetty kytkinlaitekaappi on varustettu ovella 1, joka on saranoilla 2 ripustettu oven kehyksen 3 toiseen sivupylvääseen. Kehyksen 3 vastakkaiseen sivupylvääseen on saranoilla 4 kiinnitetty lista 5, jonka muodostaa L:n muotoon taivutettu profiili, joka on yhtä pitkä kuin ovi. Keskelle listaa 5 on kiinnitetty kädensijaksi muotoiltu lukon kieli 6, joka on väännettävissä vaakasuoran puikon 7 ympäri.The switch cabinet shown is provided with a door 1 suspended by hinges 2 on the second side post of the door frame 3. Attached to the opposite side pillar of the frame 3 by a hinge 4 is a strip 5 formed by an L-shaped profile as long as the door. Attached to the middle of the strip 5 is a locking tongue 6 shaped as a handle, which can be rotated around a horizontal pin 7.

Lukon kieli 6 on sovitettu toimimaan yhdessä oveen 1 kiinnitetyn salvan 8 kanssa.The tongue 6 of the lock is adapted to co-operate with a latch 8 attached to the door 1.

Lukkolaite avataan otteella nostamalla lukon kieli 6 ylöspäin ovessa 1 olevasta salvasta 8, minkä jälkeen lukon kiel-tä ja siten myös listaa 5 väännetään ulospäin pistekatkoviivoina kuviossa 2 esitettyyn asentoon. Ovi 1 voidaan nyt avata.The locking device is opened by gripping by lifting the lock tongue 6 upwards from the latch 8 in the door 1, after which the lock tongue and thus also the strip 5 are twisted outwards as dotted lines to the position shown in Fig. 2. Door 1 can now be opened.

Listan 5 keskellä oleva puikko 7 työntyy esiin listan 5 sisäpuolella ja menee oven ollessa lukittuna ovessa 1 olevaan puikon mukaan sovitettuun reikään. Siten saadaan lisävarmuus, että kaappi pysyy kiinni mahdollisen valokaaren sattuessa kaapissa.The pin 7 in the middle of the strip 5 protrudes inside the strip 5 and, when the door is locked, enters the hole in the door 1 fitted according to the rod. This provides additional assurance that the cabinet will remain closed in the event of a possible arc in the cabinet.
