Definitions
- the invention relates to the door frame of a lift shaft conclusion, wherein in a chamber of the door frame an elevator control arrangement is arranged.
- EP 1 518 815 A1 discloses an elevator shaft termination of a building with a door frame fixed in the building and with movable doors.
- the elevator shaft closure separates an elevator shaft of the building from a floor of the building, wherein a lift control arrangement is arranged in a chamber of the door frame.
- the arrangement of the elevator control arrangement within the door frame is made possible inter alia by the fact that the elevator control arrangement can be made smaller today and the power consumption and the resulting waste heat could be reduced and thus, for example, no space-consuming ventilation systems are required.
- An elevator control arrangement comprises, as disclosed in EP 1 518 815 A1, an elevator control unit and means for mounting and protecting the elevator control unit.
- the elevator control assembly is therefore as a whole component with a few simple steps in an elevator system and expandable.
- the elevator control unit essentially comprises assemblies which are required for the control and / or regulation of the elevator installation. Furthermore, such an elevator control unit can contain the necessary interfaces and input modules for the service of the elevator installation and the diagnostics and can have a power supply unit for the voltage supply.
- the elevator motor also arranged in the elevator shaft is connected via the power electronics to the power grid and is driven by control signals of the elevator control unit.
- the object of the present invention is to provide a door frame with an elevator control arrangement, which is easy to maintain and to control and which requires a low installation cost and material costs.
- a door frame of a lift shaft closure has a chamber in which an elevator control arrangement is arranged.
- the elevator shaft closure separates a lift shaft of a building from one floor of the building.
- the elevator control arrangement includes an elevator control unit and at least one power electronics unit which can be connected to an elevator motor.
- the formation of the chamber or its very limited volume depends on the choice of profile cross-sections, which have the Moszargenmaschine. If the door frame is formed from tubular profiles, the chamber is arranged in the interior of the Terzargenprofils. If the door frame is formed from angle sections and / or U-profiles, a side wall of the chamber may also be formed by the masonry of the building. To facilitate the maintenance, the elevator control arrangement is usually installed in a vertical Monzargenelement or in the door jamb.
- the drive is often arranged in the elevator shaft itself.
- the elevator control assembly is located in an area of an elevator shaft termination, while the power electronics unit, which is usually part of a frequency converter, is located in the elevator shaft near the drive. This is because power electronic units generate heat. Furthermore, their electrical and / or magnetic fields or electrical and / or magnetic waves can sensitively disturb the elevator control unit.
- the power electronics unit for operating an elevator motor is preferably part of an electronic frequency converter.
- the electronic (static) frequency converter consists of a rectifier, which feeds a DC or DC link, and an inverter fed from this DC link as well as other electronic components, for example for controlling the inverter.
- the DC link consists of a capacitor for smoothing the DC voltage and an inductance for suppression. As a rectifier both uncontrolled and controlled bridges are used.
- the supply of the DC link can also be done with an active power factor correction (PFC) when using a controlled bridge.
- PFC active power factor correction
- the inverter works exclusively with power electronic switches (controlled bridges).
- MOSFETs Metal Oxide Semiconductor Field Effect Transistors
- IGBTs Insulated Gate Bipolar Transistors
- IGCTs Integrated Gate Commutated Thyristors
- each power supply phase can be connected directly to each phase of the load via semiconductor switches.
- the intermediate Circle with the same size is thus eliminated.
- a direct conductor with thyristors can only produce output frequencies smaller than the input frequency.
- DC link converters and direct converters with IGBTs can also generate output frequencies that are above the input frequency.
- Direct converters are also capable of regenerative feedback.
- Frequency converters generate strong electrical interference signals on the motor supply line, which not only can disturb other loads, but also lead to an increased insulation load in the motor.
- the motor supply line must often be screened to avoid disturbance radiation.
- a so-called sine-wave filter between inverter and motor can also remedy this situation.
- Such sine-wave filters differ from a line filter in their lower cut-off frequency and higher load capacity.
- the frequency converter is able to transfer energy from the DC link to the motor in both directions of rotation and also back into the DC link during braking, this is called four-quadrant operation. Since the intermediate circuit due to its structure can only store a certain energy nondestructively, measures to reduce the stored energy must be taken.
- a variant that is usually used in low-cost frequency converters is the conversion of electrical energy into thermal energy with the so-called "brake chopper", a braking resistor that is switched on by an electronic switch, but with larger amounts of energy this process is ecological as well as economical
- regenerative converters that can be used to transfer the energy from the DC link back to the power grid, so that all types of motors with regenerative frequency inverters can be operated as a generator, even if the speeds are variable Elevators, escalators and moving walks interesting.
- the integration of the power electronics unit according to the invention in the elevator control arrangement overcomes the prejudice that the heat development of the power electronic unit and its emission of interference influences are too great to be arranged in the narrowest space in the chamber of the door frame with the elevator control unit. Since the waste heat is dissipated in the elevator shaft and the units are cleverly arranged in the elevator control arrangement using the surrounding components, integration is possible.
- the advantages of integrating the power electronics unit in the elevator control system are manifold. First, the cost is significantly reduced, since only a wiring of the engine with the elevator control system and the elevator control system must be connected to the electrical grid. Furthermore, no separate power supply line between the elevator control arrangement and the power grid is necessary because the power supply of the elevator control system feeds the elevator control unit and the power electronics unit.
- the elevator control unit and the power electronics unit can be matched and adjusted to one another. Furthermore, the entire elevator control arrangement can be tested in the factory. As a result, complicated setting work is unnecessary during assembly, repair or maintenance of the elevator installation. With a few simple steps, the entire elevator control arrangement and thus according to the invention the elevator control unit and the power electronics unit can be replaced.
- the elevator control arrangement is also accessible from the elevator shaft to achieve this, the door frame in the region of the chamber may include a directed against the elevator shaft opening.
- the elevator control arrangement has a main carrier on which the elevator control unit and the power electronics unit are arranged. When installed, the opening is closed by the main beam. The opening must be closed, so that no fire gases can penetrate and in case of fire, the fire does not spread over the elevator shaft and the opening in the door frame in the floors.
- the elevator control arrangement does not overheat in this spatially narrow chamber of the door frame and this does not lead to malfunction of the elevator control unit, for faster aging or even destruction of the electronic components, at least the waste heat of the power electronics unit must be removed from the chamber. This can not be done on the door itself, as this would heat otherwise.
- the waste heat in the elevator shaft By dissipating the waste heat in the elevator shaft, the door frame approximately at room temperature and the user is not disturbed by a heated door frame.
- the waste heat of the elevator control unit in the elevator shaft can be removed.
- the chamber has electrically conductive chamber walls which are part of the mutual shielding of electrical and / or magnetic fields and electrical and / or magnetic waves of the elevator control unit and the power electronics unit. If the door frame is made of an electrically conductive tube profile, this is already given.
- shielding plates must be arranged when one side of the chamber is limited by the masonry of the building.
- the main carrier has a cooling air duct formed by walls, wherein the cooling air duct connects a suction opening formed on the main carrier with an outlet opening formed on the main carrier.
- the suction opening and outlet opening of the main carrier are directed to the elevator shaft in the installed state.
- the elevator control unit and the power electronics unit are further arranged.
- At least one wall of the cooling air shaft is electrically conductive and is therefore part of the mutual shielding of the elevator control unit and the power electronics unit of electric and / or magnetic fields and electric and / or magnetic waves, which emanate in operation from these units, in particular from the power electronics unit. In most cases, parts that serve the shield, electrically connected to ground, so that even electrostatic charges can be dissipated.
- the feature "arranged on the wall” means that the unit is arranged in the immediate vicinity of the wall.
- the power electronics unit and the elevator control unit therefore do not necessarily have to rest on the wall surface. They can be connected by means of spacers to the wall or, for example, be held by a mounting bracket attached to the main carrier at a defined distance parallel to the wall.
- At least one of the following units generating waste heat can be arranged on the walls of the cooling air shaft:
- a power supply (transformer with rectifier) for supplying the elevator control unit
- a power supply for supplying batteries
- Another power electronics unit for example, for feeding back the electrical energy generated by the elevator motor in a power grid.
- the second power electronics is only necessary if the first power electronics is not regenerative or their recuperated electrical energy is used to charge batteries.
- the braking energy of the elevator motor is thus not easily converted by means of heating resistors into heat, but used. All the units listed above also generate considerable waste heat in the narrow chamber, so that their waste heat must be dissipated through the cooling air shaft in the elevator shaft.
- at least one wall of the cooling duct is electrically conductive and is part of the mutual shielding of the elevator control unit and the heat-generating units with each other. Part of the mutual shielding means that the conductive wall of the cooling air duct contributes to the shielding of the electromagnetic interference influences of the respective other units, but does not necessarily accomplish them completely.
- unit is not necessarily meant a physical unit, for example, a power electronics unit, a power supply or the elevator control unit may also comprise a plurality of interconnected interconnecting and equipped with electronic components printed circuit boards.
- the term “unit” thus refers to the function of a component or a group of components.
- One way to use the walls of the cooling duct efficiently for shielding is that at least one step is formed on at least one wall of the cooling duct. At one stage only the elevator control unit or only one power electronics unit is arranged. By grading the wall or walls, portions of the ventilation duct protrude between the units thereby forming part of the shielding. The number of additional shielding covers, shielding plates and screening hoods can thereby be minimized, as well as possible gaps and holes in the shield, which reduce their shielding capacity.
- openings can be arranged in the walls.
- the heat sinks of components of the power electronics unit and / or of the elevator control unit extend into the cooling air shaft.
- the openings through the circuit boards of the power electronics unit and / or the elevator control unit can be sealed gas-tight.
- At least one power electronics unit can be arranged in the cooling air shaft.
- the elevator control unit can be arranged on a side of a wall facing away from the cooling air duct, the electrically conductive wall being arranged between the at least one power electronics unit and the elevator control unit.
- the power electronics unit and / or the elevator control unit may be covered by an electrically conductive shielding cover, a shielding hood or a plurality of shielding plates, so that they are completely enclosed with electrically conductive parts.
- An exception may be the projecting into the cooling air duct heat sink, which should be in order to optimize heat dissipation with the cooling air flow in touch.
- the electrically conductive walls can be made of sheet steel, aluminum or a soft magnetic nickel-iron alloy of high magnetic permeability or coated with these materials.
- the walls have a high thermal conductivity.
- these may themselves serve as heat sinks when connected to the heat generating electronic components of the power electronics unit and / or the elevator control unit.
- cooling air duct has a vertical orientation, can be set by the heat input of the power electronics unit a chimney effect, through which the cooling air flows through without further means by itself.
- the at the outlet opening and Suction opening passing elevator car can significantly affect this automatic cooling air flow and possibly bring to a standstill.
- a fan is preferably arranged in the cooling air shaft.
- the dissipated waste heat of the power electronics unit depends on the power consumption or the power output of the elevator motor, preferably also varies the applied cooling capacity of the cooling air duct and the blower.
- two blowers can be arranged in parallel in the cooling air shaft, depending on the dissipated heat, a fan or both fans are in operation.
- the cooling air duct can also be divided into, for example, two channels, so that the first fan presses the cooling air through the first channel and the second fan presses the cooling air through the second channel. Such a division may be useful if, for example, two power electronics units are integrated in the elevator control arrangement.
- a temperature sensor can be arranged in the power electronics unit and / or in the elevator control unit, the signals of the temperature sensor serving to control and regulate the blower or the fans.
- the intake opening and the outlet opening may comprise flow baffles which, for the purpose of supporting the cooling air flow in the cooling air shaft, align with the direction of travel of an elevator car traveling in the elevator shaft.
- An elevator shaft termination of a building has, as stated above, a door frame fastened in the building with a chamber in which the elevator control arrangement with a frequency converter integrated according to the invention is arranged. On the door frame, movable doors are also guided, which are also part of the elevator shaft closure.

- a fan 25 is arranged in the cooling air duct 19. Whether the blower motor is located within the cooling duct 19 or as shown in the chamber 16 depends on whether the blower motor needs to be cooled and which mounting position causes the least noise.
- blower 25 makes it possible to determine the order of the units 20, 21 which must first be cooled.
- it is the temperature-sensitive elevator control unit 20.
- a respective temperature sensor 20.8, 21.8 are arranged to monitor the operating temperature of these units 20, 21. Their signals are fed to a control device 26, which controls the speed of the fan motor.
- the door frame 14, the main support 16.2 and the walls 19.1, 19.2, 19.3 of the cooling air duct 19 are made of metal, only a shielding plate 24 between the power electronics unit 21 and the elevator control unit 20 must be arranged as possible gapless for shielding. Since no printed circuit boards with interference-sensitive electronic elements are arranged in the cooling air duct 19, the connecting lines 27 which connect the units 20, 21 to one another can be guided through the cooling air duct 19 so that they are shielded by the walls 19.1, 19.2, 19.3.
- a third embodiment of a built in the chamber 16 of the door frame 14 elevator control assembly 38 is shown in Figure 6 in a sectional elevation.
- This third embodiment also essentially corresponds to the two exemplary embodiments described above with an elevator control unit 20, a first power electronics unit 21 and a power pack 18.4.
- the first difference lies in the installation concept of the elevator control arrangement 38 in the chamber 16.
- the elevator control arrangement 38 is designed as a push-in, which can be installed or removed from the floor side.
- the floor panel 31 is integrated in the elevator control arrangement 38.
- a second power electronics unit 33 may be arranged in the middle of the cooling air shaft 19, whereby cooling air flows around both flat sides of the second power electronics unit 33.
- the second power electronics unit 33 may also be arranged in any position in the cooling air shaft 19, always provided that the flow of cooling air is ensured. It is also true for this arrangement variant that the second power electronics unit 33 is arranged on the wall of the cooling air shaft 19, since the board of the second power electronics unit 33 is fixed on the front side by screws 39.7 on a fourth wall 19.6 of the cooling air shaft 19.
- the third difference relates to the arrangement of flow guide plates 34, 35 in the elevator shaft 11.
- both the outlet opening 16.6, and the suction port 16.5 may be equipped with these.
- only one of the two openings 16.5, 16.6 Strömungsleitbleche 34, 35 have.
- These are arranged pivotably and, in accordance with the openings in the elevator shaft in the area of the opening. 16.5, 16.6 aligned prevailing flow conditions when an elevator car 39 passes them.
- the orientation of the flow baffles 34, 35 aims to ensure that the air flow indicated by arrows in the cooling air duct 19 always has the same flow direction.
- the flow baffles 34 of the suction opening 16.5 can be pivoted independently of the flow baffles 35 of the outlet opening 16.6.
- the outlet opening 16. 16 and / or the suction opening 16. 5 can also be closed by the flow guide plates 34, 35 for a short time.
- FIG. 7 shows, in a cutaway elevation, an elevator control arrangement 48 installed in the chamber 16 of the door frame 14 in a fourth embodiment.
- This has a cooling air duct 49, which is divided by a partition wall 19.9 in a first channel 49.1 and a second channel 49.2.
- a first fan 45 and in the second channel 49.2 a second fan 46 is arranged.
- This subdivision of the cooling air shaft 48 allows a targeted cooling of the waste heat generating units 20, 21.
- the noise can be significantly reduced by this subdivision, since the rotational speeds of the two fans 45, 46 can be independently controlled as needed.
- the elevator control unit 20 and the power electronics unit 21 have a temperature sensor 20.8, 21.8, the signals of which are used to control the corresponding fans 45, 46.
