When the output frequency is equal to the frequency of the commercial power supply R, s, and T, the contact 12 is closed, the power frequency detection relay is closed by the pressing contact Ua, and the contact 13b and the time limit contact 13c are open. The contact 10b is already open. Therefore, when the contact is open, the VVVF device operation relay 14 is released from pressing, and the contact is open! The contact 14b is closed. Since the contact Ua is open ', the contactor 16 for the VVVF device connection is released and the contacts 16a to 16d are opened, and the contact 16e is closed.

Invention Description (13 of The phase difference of the shape is the maximum. As shown in Figure 4, when the operation time of the inverter 1C is reversed with the time ^ ^ ^, the motor 2 will be separated from the VVVF device yvvr device χ and added directly to the air. The voltage V2 will decrease according to the switching time D2. 切换 When switching is set by the relay "5", and-once the switching time T2 is over, the motor 2 is connected to the commercial power supply R, S, T 'and transferred to normal Running time D. In this way, when the switching time T2 is ensured, even if the output of the vvvf device r is not synchronized with the commercial power supply RST, as shown in Part A, a switching operation to reduce switching vibration can be achieved. This is achieved by making the motor 2 The idling reduces the residual voltage V3, so the switching vibration can be reduced. And it is better to set this switching time T2 at about 0.7 seconds to reduce the speed reduction of the human conveyor. For this, if As shown in FIG. 5, when the switching time of the motor 2 is D4, that is, when the idling time is short, the residual voltage V4 does not decrease, so as shown in part β, the “switching vibration also increases.” Turn to low-speed ascent operation as follows Now, the power contactor 7 is pushed, and the motor 2 is connected to the commercial power sources R, S, and T for high-speed rising operation. At this time, when the speed switch 9 is switched to the low-speed side, the low-speed Relay 丨 〇 is pushed 'and the high-speed relay 11 is released by the opening of the contact 10d. In addition,' the contact 10e is opened, so the switching time setting relay 15 is released and the time limit contact 15a is opened . Therefore, the contactor 17 for power supply is released, and the motor 2 is separated from the commercial power supply r, s, and t.

Description of the invention (l4) In addition, due to the switch-off time setting of the relay 15 to release the pressure, the contacts 15b will be closed. At this time, since the contact 10b is in a closed state, the VVVF device operation relay 14 is pushed and the contact 14a is closed. On the other hand, the contact 10f is opened due to the pressing of the low-speed relay 10, and after a certain period of time, the contact 13C is closed due to the time limit, so it is between + —8b — i4a — i3c — 17d — 16 — — In the circuit, the contactor 16 for the VVVF device is pushed, and the motor 2 is connected to the VVVF device}. That is, the motor 2 is temporarily separated from the commercial power sources R, S, T and idling, and then connected to the v v VF device i. At this time, as in the above-mentioned switching from low speed to high speed, since the residual voltage from the motor 2 is lowered before connection, the switching vibration can be reduced. After that, once the time limit contact 11 d is opened after a certain period of time has elapsed since the high-speed relay 11 was released, and the time limit contact 1 oc is closed after a short period of time since the low-speed relay 10 is pushed, the Vv device The output frequency of i will shift from the frequency of the commercial power sources r, S, and T to a low set frequency, and the motor 2 will decelerate. With the above structure, the residual voltage V3 of the motor 2 is lower than when starting to separate from the VV VF device or the commercial power supply R, S, T ', that is, after a certain period of time since the start of separation, such as connection Since it is connected to commercial power sources R, S, and T, or is connected to, for example, the vVVF device 1, it is possible to achieve a switching operation without switching vibration or noise with a low-cost configuration.

Press, and the high-speed relay 11 is released from pressing. Therefore, since the contact i lf is opened, the power contactor 17 is released from pressing. In addition, since the contact 14a is in an open state, the contactor 16 for the VVVF device will also be released from pushing, and the motor 2 will be idle. In addition, the contacts 17h and 16h will be closed, and the residual voltage detection device 21 will start to detect the residual voltage. The residual voltage decreases due to the idling of the motor 2.

The figure and FIG. 3 are the same. Next, the operation of the third embodiment of the present invention will be described. In this embodiment, only the switching operation is different from the previous one, so only this part will be explained. When running at low speed, the contact 10b will be closed. In this state, if the speed switch 9 in Figure 2 is switched to the high-speed side, as described above, the high-speed relay η is pushed and the contact llb will It is closed, so the vvvf device operation relay 14 will be kept pressed. On the other hand, the vvvf device 1 is pushed by the high-speed relay U, so its output frequency will increase toward the same frequency as the commercial power supply R, S, T, and the motor 2 will accelerate. When the two frequencies become the same, the power frequency detection relay 13 is pushed, the contact 13a is closed, and the time limit contact 13c is opened. Due to the opening of the time limit contact 13c, the contactor 16 for starting is released, and the motor 2 is separated from the VVVF device i and idling. In addition, because the contact 1 3a is closed, the switching time setting relay i 5 will be pushed, and the contact 15c will be closed (at this time, the contact 14c is open). Therefore, at + — 8b—15c— In the circuit of 16i-17i-24a-23, the contactor 23 for load connection is pushed, and the contacts 23a to 23c are closed. Therefore, since the load device 25 is connected to the motor 2, the residual voltage of the motor 2 is reduced. In addition, because the contact 15c is closed, the separation time setting relay 24 is pushed, and after a certain period of time, because the time contact 24a is opened, the load connection contactor 23 is released, and the contacts 23a to 23c Is open. Therefore, the load device 25 is separated from the motor 2. --------------------- ^ ----------------------, 玎 ---- --------------- 4 (Please read the precautions on the back before transcribing each page of this page) This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ) 17 312735 504486 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (18) On the other hand, due to the push of the switching time relay 15, after a certain period of time, the time limit contact 1 5 a will be closed, so the power supply contactor 17 will be pushed, and contacts 17a to 17c will be closed. That is, 'motor 2 accelerates to the frequency of commercial power supply r' S, T in VVVF device 1, it is temporarily separated from VVVF device 1 and idling, and connected to load device 25, and then connected to commercial power supply r, s, t while running. Fig. 9 is a diagram showing a voltage waveform at the time of switching between the contactor 16 for a VVVF device and the contactor 17 for a power source. Due to the connection of the load device 25, after a certain period of time T5, as shown in Part C, the residual voltage of the motor 2 decreases, and the switching vibration also decreases. In the third embodiment of the present invention, the load device 25 is separated due to the end of the time limit of the separation time setting relay 24. If this is used in the aforementioned residual voltage detection device 21, it can be clearly known that when the residual voltage is lower than Separation is also possible when the value is less than the specified value. In the above configuration, since the load device 25 is used to actively consume the energy of the motor 3, the switching time can be shortened, and the switching vibration can be reduced.

The contactor 23 is pushed, the contacts 2 "to 23c are closed, and the motor 2a is connected. In addition, since the contact 16e is also closed when the contact 23d is closed, the power contactor 17 is pushed, and the motors 2 and 2a are connected to the commercial power sources R, S, and T. In addition, since the contact for load connection | § 23 is pushed down by the record, the motor 2 and 2a are used to perform the operation.

In addition, the present invention is applied to the aforementioned improved manned conveyor control device. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (21 × 297 mm). 22 312735 504486 A7 B7 In the fifth aspect, the invention description (23) is provided with a residual voltage detection device for detecting the residual voltage of the driving motor. In addition, when switching from low-speed operation to high-speed operation, some of the driving motors are separated from the conversion device, and after detecting that the residual voltage drops below a predetermined value, all the motors are connected to a commercial power source. In addition, when switching from high-speed operation to low-speed operation, all the driving motors are separated from the commercial power supply, and after detecting that the residual voltage drops below a specified value, some of the motors are connected to the conversion device. Since this can reduce the residual voltage of the motor earlier, switching vibration can be reduced. Further, the present invention is provided with a load device for reducing the residual voltage of a plurality of driving motors in the aforementioned improved manned conveyor control device. In addition, when some or all of the plurality of motors are separated from the conversion device or the commercial power supply, they are connected to the motor and the load device. Since the residual voltage of the motor can be effectively reduced by this, the switching time can be shortened and the switching vibration can be reduced. In addition, the present invention includes a passenger control device for detecting the presence or absence of a user of the human conveyor in the improved human conveyor control device. When a user is detected, the passenger conveyor is switched from low-speed operation to high-speed operation. In addition, when no user is detected, the passenger conveyor will switch from high-speed operation to low-speed operation. This makes it possible to achieve a high-reliability, low-speed construction, and a speed change of a manned conveyor that can respond to the presence or absence of users. In addition, the present invention is a manned conveyor provided with the aforementioned manned conveyor control arrangement. This makes it possible to switch between low-speed operation and high-speed operation without switching vibration or noise.
