HISSIN ENERGIANSÄÄSTÖLAITELIFT ENERGY SAVING DEVICE

Tämän keksinnön kohteena on patenttivaatimuksen 1 johdanto-5 osassa määritelty järjestelmä hissin energian säästämiseksi.The present invention relates to a system as defined in the preamble of claim 1 for saving energy in an elevator.

Aikaisemmin ei ole toteutettu normaaleissa volyymihisseissä energiansäästöä, vaan hissin jarrutusenergia on hävitetty ns. jarruvastuksessa. Nykyinen standardiratkaisu on vastukseen 10 jarruttava taajuusmuuttajakäyttö. Tämä systeemi on suhteellisen kallis ja siinä esiintyy laatu- ja häiriöongelmia. Ratkaisuna edellä mainittuihin epäkohtiin esitetään keksintönä uudentyyppinen järjestelmä hissin energian säästämiseksi ja edellä mainittujen epäkohtien poistamiseksi. Keksinnönmukaiselle järjestel-15 mälle on tunnusomaista se, mitä patenttivaatimuksen 1 tunnus-merkkiosassa on esitetty. Keksinnön muille sovellutusmuodoille on tunnusomaista se, mitä muissa patenttivaatimuksissa on esitetty .In the past, energy savings have not been realized in standard volume elevators, but the braking energy of the elevator has been eliminated. brake resistor. The current standard solution is the inverter 10 braking drive operation. This system is relatively expensive and has quality and interference problems. As a solution to the above drawbacks, the invention provides a new type of system for saving energy in the elevator and eliminating the above drawbacks. The system according to the invention is characterized in what is stated in the characterizing part of claim 1. Other embodiments of the invention are characterized by what is stated in the other claims.

20 Keksinnöllä saavutetaan mm. seuraavia etuja: - systeemi on halvempi ja häiriöttömämpi kuin verkkoonjarruttava taajuusmuuttaja - varavoimakäyttö on toteutettavissa ilman merkittäviä lisäkustannuksia 25 - sähkökatkon aikana voidaan varmistaa mm. valaistuksen, mer-j kinannon ja kaukovalvonnan toiminta - energian säästö on noin 20..30 % vaihteellisessa hississä ja noin 50..60 % vaihteettomassa hississä, kun verrataan vastuk- .:. seen jarruttavaan taajuusmuuttajakäyttöön, joka on nykyinen • > * » standardiratkaisu - verkkoon menevän tehon ongelmien poistaminen * · · - hyötysuhteen paraneminen » · · • · ’ Seuraavassa keksintöä selostetaan yksityskohtaisemmin esimerkin ‘•35 avulla viittaamalla oheiseen kuvioon, jossaThe invention achieves e.g. the following advantages: - the system is cheaper and less interfering than the mains-braking frequency inverter; - the stand-by power supply can be implemented at no significant additional cost 25; lighting, merchandising and remote control operation - energy saving is about 20..30% in a gear elevator and about 50..60% in a gearless elevator when compared to the counter-:. The present invention will be explained in more detail by way of example, with reference to the accompanying figure, in which: -> * »standard solution - elimination of network power problems * · · - efficiency improvement» · ·

Kuvio 1 esittää yksinkertaistettuna keksinnönmukaista kytkentää.Figure 1 illustrates in simplified form the connection according to the invention.

Kuviossa 1 tuodaan 3-vaiheinen verkkojännite taajuusmuuttajalle 112008 2 15, joka muodostuu tasasuuntaajasta 3, vaihtosuuntaussillasta 2 sekä näiden välisestä välipiiristä 4,10,11. Kun hissi ajaa ke-vyeeseen suuntaan, mikä tarkoittaa, että tyhjäkori ajaa ylöspäin ja vastapaino menee alaspäin, niin sähkövirtaa saadaan välijän-5 nitepiiriin 4,10,11 johteiden 10 ja 11 väliin käyttömoottorista 1, joka toimii generaattorina. Vaihtosuuntaussilta 2 muuttaa käyttömoottorilta l tulevan vaihtojännitteen tasajännitteeksi välijännitepiirin 4,10,11 johteita 10 ja 11 varten. Tasajänni-temuuttajalla 5 jännite ladataan akkuun 6. Keksinnönmukaisessa 10 ratkaisussa tarvitaan vain yksi akku 6. Taajuusmuuttajahissien jarrutuksessa syntyvä teho (jännite on noin 650V ja virta 1...3-A) muutetaan hakkurityyppisellä tasajännitemuuuttajalla 5 noin 30V / 20...50A tasolle, joka sopii hyvin hissin teholähteeksi ja 24V akkujen lataukseen. Hakkurityyppinen muuttaja tarkoittaa 15 puolijohteilla ja pienikokoisilla ferriittimuuntajilla toteutettua muuntajaa, jossa hyötysuhde on muuntajan veroinen, mutta jännitteen säätötarkkuus on parempi. Samaa tasajännitemuuuttajaa 5 käytetään koko ohjausjärjestelmän tehon syöttöön.Fig. 1 provides a 3-phase mains voltage to the inverter 112008 2 15, which consists of rectifier 3, inverter bridge 2 and intermediate circuit 4,10,11 between them. As the elevator travels in a light direction, which means that the empty car travels upward and the counterweight goes downward, electric current is supplied to the intermediate circuit 5 nitro circuit 4,10,11 between the conductors 10 and 11 from the drive motor 1 which acts as a generator. The reversing bridge 2 converts the alternating voltage from the drive motor 1 to a DC voltage for the leads 10 and 11 of the intermediate voltage circuit 4,10,11. In the 10 solution according to the invention, only one battery is needed 6. The power generated by braking the drive elevators (voltage is about 650V and current 1 ... 3-A) is changed by a switch-type DC converter 5 to about 30V / 20 ... 50A. , which is well suited for lift power supply and charging 24V batteries. A switch-type converter means 15 transformers implemented with semiconductor and small ferrite transformers, with efficiency equal to that of the transformer, but with better voltage control accuracy. The same DC converter 5 is used to power the entire control system.

20 Hissin turvapiirille, joka muodostuu hissin ovi- ja muista turvakytkimistä ja joka estää hissin liikkeellelähdön, jos ovet eivät ole kiinni tai muuten olisi vaarallista lähteä liikkeelle, voidaan tehdä kyseisellä tasajännitemuuuttajalla 5 korotettu . ^ jännite. Hissi toimii energianlähteenä noin 20% ajoajasta, '25' jolloin akkua 6 ladataan suurella virralla 20...50A ja noin 80% [ ajasta akun 6 energiaa käytetään hissin ohjauslaitteiden, oh-’· jausjärjestelmän, jarrun ja merkinannon ym. tehonsyöttöön.20 The safety circuit of the elevator, which consists of elevator door and other safety switches and which prevents the elevator from moving if the doors are not closed or otherwise would be dangerous to move, can be increased by the respective DC converter 5. ^ voltage. The elevator acts as an energy source for about 20% of the travel time, '25' whereby the battery 6 is charged at high current 20 ... 50A and about 80% of the time battery 6 is used to power the elevator controls, control system, brake and signaling, etc.

·...' Energiaa syötetään mm. hissin ohjausosaan, joka on merkitty numerolla 7. Tämä ohjausosa on merkittävä sähkön kuluttaja.· ... 'Energy is supplied eg. to the elevator control part marked 7. This control unit is a significant consumer of electricity.

> »« :,30 Hissin jarrulla 8 tarkoitetaan lähinnä jarrun sähkömagneettia, joka myös kuluttaa melko paljon energiaa ja hissin valaistuksel-·< la 9 tarkoitetaan lähinnä korivaloa, joka tarvitsee yleensä akun varavoimalaitteeksi. Kondensaattori 4 vähentää verkkosyöttöön meneviä suurtaajuisia häiriöitä.> ««:, 30 Elevator brake 8 is mainly a brake electromagnet which also consumes quite a lot of energy, and elevator lighting is mainly a body light, which usually needs a battery as a backup power supply. Capacitor 4 reduces high frequency interference to mains supply.

Jarrutustilanteessa syntyvä energia muutetaan alemmalle jännit-; teelle ja syötetään edellämainituille laitteille ja akkuun (6). Jos ei jarruteta, niin toiminta on melkein sama kuin edellä, 112008 3 mutta teho otetaan sähköverkosta. Jarrutusenergian siirtymistä akkuun (6) kontrolloidaan säätämällä jännite sopivaksi samoin jännitteen säätämisellä varmistetaan, että akussa (6) on tarpeeksi jännitettä.The energy generated during braking is converted to a lower voltage; and fed to the aforementioned devices and the battery (6). If not braked, operation is almost the same as above, 112008 3 but power is drawn from the mains. The transfer of braking energy to the accumulator (6) is controlled by adjusting the voltage to a suitable level, and adjusting the voltage ensures that the accumulator (6) has sufficient voltage.

Toinen keksintöön liittyvä piirre on hissin käyttö- ja ohjausjärjestelmän teholähteiden integroiminen yhdeksi kokonaisuudeksi. Ne ovat olleet erillisiä ja siten aiheuttaneet lisäkustannuksia sekä laatu- ja häiriöongelmia. Kaksisuuntaisella muutta-10 jalla voidaan toteuttaa hissin varavoimakäyttö alennetulla nopeudella muutaman tunnin ajan.Another aspect of the invention is the integration of the power supplies of the elevator drive and control system into a single entity. They have been discrete and have caused additional costs and quality and disruption problems. Bidirectional move-10 can provide emergency lift operation at reduced speed for a few hours.

Alan ammattimiehelle on selvää, että keksinnön eri sovellutus-muodot eivät rajoitu yksinomaan edellä esitettyihin esimerkkei-15 hin, vaan ne voivat vaihdella jäljempänä esitettävien patenttivaatimusten puitteissa.It will be apparent to one skilled in the art that the various embodiments of the invention are not limited to the Examples above, but may vary within the scope of the claims below.
