救出運転してしまう不具合がある。2. Description of the Related Art An elevator landing device has a function of detecting a power failure state and shifting to a rescue operation when a power supply of a customer is interrupted. Since the main breaker is connected to the secondary side of the breaker, if the main breaker on the main control unit is shut down during maintenance or inspection or when remodeling the main control unit, the power outage detection relay detects the power outage and the elevator There is a problem that rescue driving is performed up to the nearest floor landing.

転をしないようにした構成である。[0003] In order to solve the above-mentioned disadvantages, several configurations have conventionally been adopted. One is to provide an auxiliary contact that operates in conjunction with the operation of the main breaker on the main control device side, open the auxiliary contact when the main breaker is shut off, and prevent rescue operation even if the power failure detection relay operates. This is the configuration.

In the latter configuration, the breaker in the landing device must be shut off by opening the door of the landing device main body before shutting off the main breaker on the main control device side, which is very complicated. In addition, the main breaker on the main control device side is shut off in an emergency, but there is a problem that the elevator is moved by rescue operation in time for shutting off the breaker in the landing device.

For example, when an overcurrent accident or a ground fault accident occurs on the main control device side for some reason during normal operation, the main control device-side main breaker 2 trips, and at the same time as this trip, the main breaker auxiliary contact 17 opens. In a power outage, rescue operation cannot be performed. Further, even if an inverter device is provided in the landing device main body 8 and the rescue operation can be performed independently, the rescue operation cannot be performed if the main breaker auxiliary contact 17 is turned off as described above.

When a ground fault occurs during operation of the elevator and only the main breaker 2 or the customer breaker 22 and the main breaker 2 trip together, the earth leakage relay 41 is turned on, and the earth leakage relay normally open contact 42 is closed. And
The control device power supply relay 27 is turned on, power is supplied to the rescue operation control device 28 in the manner described above, and the rescue operation is performed.

If the load-side earth leakage relay 55 does not detect a predetermined time, the timer 60 counts up and operates.
This closes the normally open contact 60a of the timer 60 and turns on the main circuit contactor 54, so that the main circuit contact 54a

In this case, it is checked whether a ground fault has occurred in the motor. If there is no ground fault, the rescue operation is performed as it is. If a ground fault has occurred, the rescue operation is stopped before closing the main circuit contact 54a. In addition, it is possible to protect equipment related to the rescue operation.

切り忘れ等が考えられることから万全ではない。In the case of the circuit configuration shown in the embodiment of FIG. 2, for example, this landing apparatus can perform rescue operation at the time of trip of the breaker, but conversely, if the main breaker 2 is shut off during elevator work or the like, Also, a path is formed of the normally closed contact 35 of the power failure detection relay 23, the normally open contact 36 of the customer primary side power failure detection relay 21, the normally closed contact 6b for the normal operation contactor, and the normally closed contact 33 for the inspection operation. In order to turn on the control device power supply relay 27 and enter the rescue operation mode, it is necessary to once turn off the customer-side power failure detection relay-side breaker 22 before turning off the main breaker 2. The current path of the power failure detection relay breaker 22 may be an electric wire similar to the signal line, and is not restricted by an installation place or the like. For example, if the current path is arranged side by side with the main breaker 2, no particular trouble occurs.
It is not perfect because you may forget to cut.

Since it is determined that the main breaker 2 has been shut off due to maintenance and inspection work, the control circuit power supply relay 27 is not turned on.
