1. Tighten the laces before elevator panel factory the ride, pay attention to loose, dragging clothing (such as long skirts, dresses, etc.) to prevent being dragged by the edge of the step, comb plate, apron board or inner cover. 2. At the entrance of the escalator or moving sidewalk, passengers should board in order, and do not push each other.
It is especially important to pay attention when there are elderly people, children and children with low vision. 3. When passengers step on the horizontal running section of the step at the entrance of the escalator step, they should pay attention to leave their edges and stand inside the yellow safety warning frame of the step pedal. Do not step on the junction of the two rungs to avoid falling down due to the height difference between the front and back rungs when the rungs run to the inclined section.
When riding the escalator or sidewalk, do not touch your shoes or clothing to the apron or inner cover under the glass or metal fence, to avoid personal injury caused by hanging when stepping. 4. When riding, you should stand in the direction of the step movement and hold the hand strap in one hand to prevent your body from falling due to accidents such as emergency stop or push by others. If the handrail is not synchronized with the running of the rung due to a malfunction, pay attention to adjusting the position of the hand at any time. 5. At the exit of the escalator or moving walkway, passengers should lift their feet quickly and follow the trend of the step, and step on the front plate across the comb plate to prevent it from falling down or being caught by shoes. 6. Please do not stay at the escalator or moving walkway exit, so as not to affect the arrival of other passengers.
This type of transformer is called a step-down transformer. Array transformers can reduce the 380V voltage to 220V, 100V, 42V, 2OV, and the 22OV voltage to 100V, 42V, 30V, and 2OV. The transformers used are either single-phase or three-phase. Single-phase transformer can be used as power supply or connected to AC appliances and meters, or connected to single-phase rectifier; three-phase transformer can supply power to the three-phase rectifier and the drive motor of the door. Rectifier Rectifier is an electronic component used to supply DC electrical equipment. The elevator uses a two-phase rectifier combined according to the bridge schematic diagram and a three-phase rectifier that significantly reduces the pulsating rectification current. It can ensure that the electromagnetic relays, contactors, interlocking buttons and other components powered by the rectifier work smoothly.
