Otu OTIS OVF20 Elevator Inverter si arụ ọrụ

Inverter OTIS OVF20 na-arụ ọrụ dị oke mkpa na sistemụ ebuli elu nke oge a, na-ahụ na ọrụ ya dị mma ma dịkwa nchebe. Isi ọrụ ya bụ ịtụgharị ike AC enyere na ebuli elu ka ọ bụrụ mmepụta AC ugboro ugboro a na-achịkwa nke na-agbanwe agbanwe nke na-akwali moto ahụ nke ọma.

Usoro a na-amalite site na ike AC na-abata, ma ọ bụ 380V ma ọ bụ 220V, nke a na-ebu ụzọ gbanwee ka ọ bụrụ voltaji DC site na sistemụ rectifier dị n'ime inverter. A na-eme ka voltaji DC a guzosie ike site na capacitors na sekit DC iji nye ọkọnọ kwụsiri ike. Inverter ahụ na-eji sistemụ modulation pulse-width (PWM) iji gbanwee DC a ka ọ bụrụ voltaji AC nwere ugboro ole a na-agbanwe agbanwe, na-emecha usoro inverter.

N'ime OVF20, ihe mbụ a na-ahụ mgbe emepechara mkpuchi ihu bụ Motion Control Board II (MCBII). Dịka aha ya si kwuo, bọọdụ a bụ ọrụ maka ijikwa sistemụ mmegharị nke ebuli elu. Ọ na-eje ozi dị ka njikọ maka akara ntinye na mmepụta niile nke OVF20 ma na-ahazi akara ndị a iji hụ na arụ ọrụ nke ọma.

Sistemụ njikwa ebuli elu—dịka LBII, LCBII, ma ọ bụ bọọdụ njikwa ndị ọzọ—na-eziga iwu ọsọ na MCBII. MCBII na-ahazi iwu ndị a yana akara mgbama ibuli elu ọzọ, gụnyere sekit nchekwa. Ọ na-eziga akara njikwa na Power Drive Board (PDB), nke na-achịkwa transistor ike dị elu n'ime inverter iji mee mgbanwe AC n'ezie. N'ụzọ bụ isi, PDB na-eme mgbanwe ike nke inverter n'okpuru nduzi nke MCBII.

Maka ọrụ ziri ezi, MCBII na-enwetakwa nzaghachi site na ihe mmetụta ọsọ PVT. Site n'ịtụnyere ọsọ nke igwe mbuli elu ahụ na ọsọ enyere iwu, MCBII na-agbanwe mmepụta moto ahụ iji nọgide na-enwe mmegharị dị nro ma bụrụ nke a pụrụ ịtụkwasị obi. Ahịrị abụọ ọzọ sitere na inverter na-enye nzaghachi ugbu a na MCBII dịka akụkụ nke sistemụ nchekwa ugbu a dị n'ime inverter. Ọ bụrụ na ọkụ mmepụta gafere uru enyere, inverter ga-akpali mmechi nchebe.

N'ikpeazụ, OVF20 nwere sistemụ resistor brek. A na-eji resistor a eme ka ebuli elu ahụ ghara ịda nke ọma, na-agbanwe ike gabigara ókè ka ọ bụrụ okpomọkụ iji hụ na a na-achịkwa ya ma nwee nchekwa.

N'ozuzu, ihe ntụgharị OTIS OVF20 na-ejikọta njikwa mmegharị ziri ezi, nzaghachi oge, na usoro nchekwa iji nye arụmọrụ a pụrụ ịdabere na ya maka igwe mbuli elu nke oge a.
