Definitions
- the present invention relates to a hermetic compressor, and more particularly to a hermetic compressor for compressing corrosive gas.
- the screw compressor that compresses refrigerant integrally connects the compressor body and the motor, that is, a rotor casing that houses the screw rotor, a motor casing that houses the stator and rotor of the motor, and In many cases, a closed structure is employed in which the refrigerant leaking from the gap between the rotor shaft and the rotor casing is sealed in the motor casing.
- the winding of the stator passes through a terminal block whose end (lead wire) seals the opening of the motor casing so that power can be supplied from the outside.
- the external terminal Connected to external terminals (external terminals).
- the external terminal has a structure of a crimp terminal in which the end of the winding is inserted and crimped.
- the terminal block cannot be made so large. In general, for standardization of parts, it is desirable that the same terminal block can be used between different products. For this reason, when an aluminum wire having a diameter larger than that of the copper wire is connected to the external terminals arranged at the same pitch as that of a normal motor, the distance between the crimping portions of the external terminals is shortened. Since ammonia has a lower insulating property than air, there is a problem that when the distance between the crimping portions of the external terminals is shortened, a dielectric breakdown occurs inside the motor, causing a short circuit.
- an object of the present invention is to provide a hermetic compressor in which heat generation and dielectric breakdown are unlikely to occur at a connection portion between a lead wire of a motor and an external terminal.
- a hermetic compressor includes a rotor casing that forms a rotor chamber that houses a screw rotor, and a motor casing that forms a motor chamber that houses a stator and a rotor of a motor.
- the stator of the motor is formed by winding a plurality of independent windings in multiple layers. It is assumed that a separate external terminal is provided for each of the windings.
- the winding may be made of an aluminum wire, preferably an aluminum wire coated with a fluororesin.
- This configuration can provide a highly corrosion-resistant compressor.
- the external terminals may be divided into a plurality of terminal blocks.
- the external terminal may be a crimp terminal that inserts and crimps an end of the winding.
- This configuration facilitates connection to the external terminals of the winding.
- FIG. 1 is a cross-sectional view of a hermetic compressor according to one embodiment of the present invention.
- FIG. 2 is a circuit diagram of a motor stator of the hermetic compressor of FIG. 1.
- FIG. 3 is a schematic cross-sectional view of one pole of FIG. 2.
- FIG. 4 is a schematic cross-sectional view of an alternative pole of FIG. 3.
- FIG. 4 is a schematic cross-sectional view of a further alternative pole of FIG. 3.
- FIG. 1 shows a hermetic screw compressor 1 according to one embodiment of the present invention.
- the screw compressor 1 is designed to compress ammonia gas, and is formed by integrally connecting a compressor body 2 and a motor 3.
- the compressor main body 2 contains screw rotors (male rotor 6 and female rotor 7) that mesh with each other in a rotor chamber 5 formed in the rotor casing 4.
- the screw rotors 6 and 7 are rotated by the rotational force of the motor rotor 11, suck in and compress ammonia gas from the suction flow path 12, and discharge the compressed refrigerant from the discharge flow path 13.
- the motor 3 is a three-phase induction motor, and in a motor chamber 9 formed by a motor casing 8 hermetically connected to the rotor casing 4, a motor rotor 11 sharing a shaft with the motor stator 10 and the male rotor 6. Is housed.
- the motor chamber 9 and the suction passage 12 communicate with each other through an opening through which a shaft shared by the motor stator 10 and the male rotor 6 passes, and ammonia gas is introduced into the motor chamber 9 from the suction passage 12. Can flow in.
- the motor casing 8 has openings 14 at the end and the upper side opposite to the rotor chamber 5, respectively. Each of the openings 14 is sealed by airtightly attaching the terminal block 16 via the spacer 15. Fixed to each of the two terminal blocks 16 are rod-like external terminals 18 connected to the ends of the lead wires 17 extending from the ends of the windings of the motor stator 10.
- the winding (lead wire 17) of the motor stator 10 is made of an aluminum stranded wire having a coating made of fluororesin.
- the external terminal 18 passes through the through hole 16 a provided in the terminal block 16, and a flange 18 a provided on the motor chamber 9 side is fitted into the recess 16 b inside the terminal block 16 to seal the through hole of the terminal block 16. Stop. Further, the external terminal 18 is fitted to the inner end portion so as to cover the end portion of the lead wire 17 from which the coating has been peeled off, and has a crimping structure that is crimped to the lead wire 17 by caulking, It is fixed to the terminal block 16 with a plurality of nuts 19 that are screwed into external screws provided at the outer end.
- the motor stator 10 can be supplied with electric power by sandwiching and fixing a connection terminal of a wiring for supplying electric power from a power source between nuts 19 screwed into the external terminal 18.
- terminal block 16 is attached to the motor casing 8 by the mounting bolt 21 together with the outer box 20 covering the outer end portion of the external terminal 18 and the spacer 15.

- the motor 9 has a winding of each phase wound twice.
- Each of the windings A1, A2, B1, B2, C1, and C2 is made of an independent aluminum stranded wire.
- each of the windings A1, A2, B1, B2, C1, and C2 is shown as one coil, but in practice, each of the windings can be wound to form a plurality of poles.
- FIGS. 3 to 5 show simplified examples of how to wind the windings A1, A2 of one pole of the stator 10.
- the windings A1 and A2 may be wound so as to form two layers around the iron core 22, as shown in FIG. 3, so that the iron core 22 is divided into two as shown in FIG. As shown in FIG. 5, they may be wound together, for example, by winding two at the same time.
- the windings A1 and A2, B1 and B2, or C1 and C2 of each layer do not form different poles, but form half of the magnetic fields of all the poles in the phase.
- Each winding A1, A2, B1, B2, C1, C2 has an impedance about twice that of the aluminum winding of each phase of the conventional equivalent motor, and the current value is about that of the conventional winding. Configured to be halved. Therefore, if the copper loss in each of the windings A1, A2, B1, B2, C1, and C2 is set to the same level as that of the conventional winding, the cross-sectional area thereof may be about one-half that of the conventional winding. However, in order to generate the same number of magnetic fluxes as before in each pole, the total length of the windings A1, A2, B1, B2, C1, and C2 is about twice that in the conventional case.
- the individual external terminals 18 are connected to the ends of the lead wires 17 at both ends of the windings A1, A2, B1, B2, C1, and C2 wound in this way.
- the wiring connected to each external terminal 18 is connected to the output terminals U, V, and W of a variable frequency power source (inverter) outside the motor 9, for example.
- the windings A1 and A2, the windings B1 and B2, and the windings C1 and C2 are connected in parallel, respectively, and the windings A1, A2, B1, B2, and C1, C2 is connected to be connected in a delta shape. Since the atmosphere outside the terminal block 16 is highly insulating and non-corrosive air, it can be wired using copper wires or other conductors, and the insulation distance between these conductors is shortened. You can also.

- the windings A1 and A2, the windings B1 and B2, and the windings C1 and C2 may be connected in series, respectively.
- the pitch of the external terminals 18 in the terminal block 16 is set to other than copper wires. Even if the motor is the same as that of the motor, the gap between the lead wire 17 and the external terminal 18 can be kept large, and a short circuit due to dielectric breakdown (discharge) can be prevented even in an ammonia atmosphere with low insulation.
- the winding of the stator 11 may be wound three times or four times or more, and in that case, three or more terminal blocks 16 may be provided.
- the windings A1, A2, B1, B2, C1, and C2 are each formed by winding a plurality of aluminum wires in which individual aluminum wires are covered with a fluororesin instead of one aluminum stranded wire. May be.
