Abstract
Description
20 25 30 35 Säkerhetskretsen består av en första kontaktor K,, en andra kontaktor K, samt en skyddstransformator T. Spolen k¿ på den första kontaktorn Kl, sekundärsidan på skyddstransformatorn T samt två brytande kontakter 5"-6" och 7"-8" på den andra kontaktorn K¿ har kopplats i en sluten krets med dörr- /låskontakter KD. kopplats mellan fasspänníngen V, Primärsidan på transformatorn T har och jorden G. The safety circuit consists of a first contactor K ,, a second contactor K, and a protection transformer T. The coil k¿ on the first contactor K1, the secondary side of the protection transformer T and two breaking contacts 5 "-6" and 7 "-8 "on the other contactor K¿ has been connected in a closed circuit with door / lock contacts KD. connected between the phase voltage V, the primary side of the transformer T has and the earth G.
Vidare har dörr-/låskontakterna KD kopplats till via en parallelkoppling av kontakter 1'-2' på den första kontaktorn K,och kontakter 1"-2" på den Mellan dörr-/låskontakterna Kn och fasspänningen V1 andra kontaktorn Kr spolarna ku och kn har kopplats kontakter 3"-4" på den andra kontaktorn Kv och spolen kzpå den andra kontaktorn 19 har kopplats parallelt med en seriekoppling av kontakterna 3"-4" och spolarna ku och ku.Furthermore, the door / lock contacts KD have been connected via a parallel connection of contacts 1'-2 'on the first contactor K, and contacts 1 "-2" on it Between the door / lock contacts Kn and the phase voltage V1 the second contactor Kr the coils ku and kn contacts 3 "-4" have been connected to the second contactor Kv and the coil kz of the second contactor 19 has been connected in parallel with a series connection of the contacts 3 "-4" and the coils ku and ku.
Kretsen fungerar på följande sätt. När dörrkontakterna KD är slutna, fungerar kontaktorn K,så att kontaktorn Kzdrar.The circuit works as follows. When the door contacts KD are closed, the contactor K works, so that the contactor Kzdrar.
Kontaktorn K, får en hållkrets via kontakterna 1"-2".The contactor K, receives a holding circuit via the contacts 1 "-2".
Samtidigt öppnas kontakterna 5"-6" och 7"-8" och kontaktorn K,faller.At the same time, contacts 5 "-6" and 7 "-8" open and contactor K1 drops.
Vid en öppen dörr-/låskrets faller bada kontaktorer K; och lg varvid fasspänningen V,kopplas bort från dörr- /låskretsen.In the case of an open door / lock circuit, both contactors K fall; and lg whereby the phase voltage V, is disconnected from the door / lock circuit.
Då dörr-/låskretsen blir hel drar kontaktorn K¿ och matar in kontaktorn Kv som förblir dragen över egen hållkontakt.When the door / lock circuit becomes complete, the contactor K¿ pulls and feeds in the contactor Kv, which remains pulled over its own holding contact.
Kretsen till spolen k, brytande kontakter S"-6" och 7"-8" på kontaktorn Kr och transformatorn T bortkopplas med För fackmannen på området står det klart, att uppfinningen inte begränsar sig till det exempel som här framförts, utan kan variera inom ramen för de efterföljande patentkraven. I \ 514 271 3 stället för en korgdörr kan det i äldre hissar finnas en grind.The circuit to the coil k, breaking contacts S "-6" and 7 "-8" on the contactor Kr and the transformer T are disconnected with For those skilled in the art it is clear that the invention is not limited to the example presented here, but can vary within the scope of the appended claims. Instead of a wicker door, there may be a gate in older lifts.
