China Home Elevator Tips For Using Elevator Emergency Device

In order to minimize the psychological and physical adverse effects of trapped people on elevators, elevator emergency devices came into being. Then the elevator emergency device of China Home Elevator , let’s talk about it below:Elevator emergency device has been fully developed as a relatively independent electromechanical product. Although the names of such devices seen on the market today are different, such as: “elevator emergency device”, “elevator power failure automatic leveling control panel”, “elevator power failure automatic rescue device”, etc., product brands and manufacturers are also relatively Many, but its hardware structure and working principle are basically the same. This type of elevator emergency device is generally composed of main control board, charging board, inverter board, interface board, battery pack and phase sequence detection.When a power failure, phase loss or phase sequence error occurs, the elevator emergency device completely takes over the control of the elevator. The specific working process is as follows: when the elevator emergency device detects the mains power failure, phase loss, and phase sequence error, it will cut off the connection between the elevator and the mains. Through its own input signal, it is detected whether all links of the elevator safety circuit are normal, whether the elevator car is stopped at a non-leveling position, and whether the elevator is in the maintenance work state. After the test result meets the conditions of emergency operation, the inverter board is started immediately, and the voltages of various levels that are inverted are directly sent to the elevator traction machine, brake, door machine and other parts. The elevator emergency device first drives the elevator to run in the up and down directions once, and then runs at a low speed in the labor-saving direction. When it is detected that the car reaches the first leveling position in the running direction, level the car, open the door and let go, and then stop working.At present, based on the control of one elevator emergency device to drive one elevator, it has developed to one tow 2 or more, and the maximum output power has reached 35kW. From the perspective of structure and working principle, it can be said that an elevator emergency device is a simplified version of an elevator control system.The above is organized and shared by HUZHOU FUJI ELEVATOR CO.,LTD.
