There is a power outage, can the elevator still be used

If the power supply circuit of the elevator is independent, the elevator can still be used after a power outage.

An elevator is a vertical lift powered by an electric motor with box-like pods that are used to carry people or goods in multi-storey buildings. There is also a stepped type, and the tread plate is mounted on the track for continuous operation, commonly known as escalator or moving walk. Stationary lifting equipment serving the specified floors.

A vertical lift has a car that runs between at least two rows of rigid rails that are vertical or have an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation within a building, regardless of the mode of drive.

According to the speed, it can be divided into low-speed elevator (less than 1 meter second), fast elevator (1 2 meters second) and high-speed elevator (more than 2 meters second). Hydraulic elevators began to appear in the mid-19th century, and they are still used on low-rise buildings today. In 1852, Otis of the United States developed a safety elevator for wire rope lifting.

In the 80s, the drive device was further improved, such as the electric motor driving the winding drum through worm drive, the use of counterweight, etc. At the end of the 19th century, friction wheel transmission was adopted, which greatly increased the lifting height of the elevator.

At the end of the 20th century, the elevator was powered by a permanent magnet synchronous traction machine. It greatly reduces the area of the computer room, and has the advantages of low energy consumption, high energy efficiency and fast lifting speed, which greatly promotes the development of real estate in the direction of super high-rise.

Electric Traction System: The function of the electric traction system is to provide power and implement elevator speed control. The electric traction system is composed of a traction motor, a power supply system, a speed feedback device, a motor speed regulating device, etc.

Electrical control system: The main function of the electrical control system is to operate and control the operation of the elevator. The electrical control system is mainly composed of a control device, a position display device, a control panel (cabinet), a leveling device, a layer selector, etc.

Some places are okay, some are not. See how your wiring is installed, hehe. Generally, elevators have power generation. Suyi doesn't stop.

It belongs to the same line.

It can't be used.

Generally, no.

The elevator stopped suddenly, and you can't go.

First of all, I would like to emphasize that there are quite a lot of safety measures in the elevator. And these safety protection devices can be divided into mechanical, electrical, electromechanical comprehensive three, wherein, mechanical safety protection devices include: speed limiter, safety gear, buffer, brake, overspeed protection device, etc.;

Secondly, the Quality Supervision Bureau also stipulates that the elevator needs to be maintained every 15 days, and safety inspections must be carried out every year;

Finally, the elevator will not fall, but will automatically stop running. The elevator traction system is composed of multiple steel cables, one steel cable is composed of multiple strands, and one strand is composed of multiple wires. The safety factor is calculated based on the total breaking load of all steel cables.

For three or more, the safety factor is 12. Each elevator is equipped with multiple wire ropes, which are suspended independently of each other.

What to do if you encounter an elevator breakdown:

1. First of all, we must be calm, although the elevator is a confined space, there will be no lack of oxygen. The trapped passengers in some news are often prone to rapid heartbeat and difficulty breathing because of fear and anxiety, coupled with uncertain waiting time for rescue;

2. The key to rescue is to ask for help. You can press the emergency call button to dial rescue**, or call the property and family**;

3. Don't try to pry open the elevator door, let alone try to climb out of the elevator (if you climb half of the elevator and wait for the elevator to resume operation, the consequences will be unimaginable);

4. Non-professionals, do not take measures that "think you are smart". Behind every major elevator accident, there are some self-proclaimed smart people who pay the price of their lives;

5. If the elevator is falling, you can try to grasp the handrail or elevator wall with both hands, and bend your legs straight against the elevator wall to reduce the damage to the joints and spine. <>

If the power supply circuit of the elevator is independent, the elevator can be used after a power failure. If the circuit is not independent, the elevator cannot be used after the power failure of the community. Therefore, it is necessary to check the distribution cabinet form first, usually the distribution cabinet with its own emergency power generation device is equipped with automatic manual switching, if it is manual, if it is necessary to use its own generator to supply power, it is necessary to first unrank the load switch with the mains, and then untie the isolation switch, then the distribution cabinet has the condition of self-power supply.

Hello dear, you can't go down when the elevator is out of power. If the elevator stops suddenly, you should press the emergency button in the elevator, report to the elevator maintenance department, and wait for the maintenance personnel to come for repairs. Even if the escalator is stopped by turning it off, it will not run again, and although the escalator can still be walked after it is closed, it is not recommended to walk.

In addition, the brake force of the escalator is actually not large, and the anti-slip device may not work, so don't step on the elevator that is out of service, and don't hesitate to gamble on other people's professional ethics with your own life. If you have to go, you must first determine whether it is artificially pressed or stop by yourself, and at the same time pay attention to the height of the stairs is higher than the ordinary stairs, and the steps will bring impact to the track and steps, which may cause new faults to the elevator, which is not conducive to personal safety.

It cannot be used unless it is an elevator equipped with a dual power system. According to the national standard, the elevators of high-rise residential buildings should be equipped with emergency power generation devices, which can be automatically or manually activated when there is no power outage in the residential section, so that the elevators can operate normally.

Can the elevator still work if there is a power outage?

Due to the high cost of equipping a dual power supply system, few developers will equip a residential elevator with a dual power supply system.

When the elevator is out of power, the lighting devices, emergency buttons and alarm devices in the elevator can be used normally.

When trapped in the elevator, do not pick up the elevator door to save yourself, do not panic, hold the handle, and wait patiently and calmly for external rescue.

If the residential elevator is equipped with a backup power supply or a backup generator, then the residential elevator can still operate normally if there is a power outage. If there is no power supply or backup generator, the elevator will also stop if the community is out of power.

China's relevant policies and regulations stipulate that Class II high-rise buildings, elevators, etc. should have dual power supplies (i.e., common power supply and standby power supply), and the power supply system will not be interrupted when the line and other faults occur. According to national requirements, many high-rise residential elevators should be equipped with dual power supplies, the community power outage, the elevator can take power from the backup power supply, to ensure the normal operation of the elevator.

What should I do if there is a power outage in the elevator?

1. First of all, don't be anxious, there is an elevator alarm ** to call, if not, use your mobile phone for help, the elevator has a contact number. The elevator has a power outage but the lighting inside should be there. If not, it's a substandard elevator.

2. Wait patiently after the fight, if there are not many people, you can do it inside, maintain your physical strength, and don't have to shout loudly.

3. Roughly analyze what causes power outages, such as natural disasters (**, no lighting in all power outages), fires (forced power outages), human factors (people beating can cause the elevator to stop), and there is a real power outage (elevator stop).

4. Then deal with it. Be prepared to save yourself, and listen to the outside if you contact the outside. Can wait to get outside rescue.

Normal is not usable, if there is an emergency power generation equipment, then it can be used, or the power supply of the elevator is independent, and the elevator can still be used after a power failure.

This mainly depends on the form of the distribution cabinet, if there is a self-provided emergency power generation device of the distribution cabinet equipped with automatic and manual switching, as well as the mains load switch and isolation switch, so that you can turn on the emergency electricity, but the emergency electricity is also temporary, or wait until the normal power after the use of the elevator.

Attention should be paid to the use of elevators:

1. Don't overload.

In the precautions for elevator use, "no overload" is the most basic and important one. Elevators are usually equipped with overload alarms. If they are overloaded, they receive a special audible notification. If you hear an alarm, you must exit immediately, otherwise the elevator will not function properly.

2. Disable the scene.

Elevators can indeed bring a lot of convenience, but if you encounter a fire or**, do not use the elevator, it is safer to escape from the fire escape. If you take the elevator blindly, if there is a sudden power outage, you may be trapped in the elevator, bringing more safety hazards.

3. Don't jump.

Many bear children may be bouncing and jolting in the elevator. But in reality, this behavior can cause the elevator to run abnormally. This is because safety protection switches are often set up in many places in the elevator.

If the elevator tilts due to jumping, it may accidentally touch the safety protection switch of the elevator, causing the elevator to malfunction, and unexpected shutdown will increase the safety hazard.

Hello, no, in the event of an elevator power outage, the elevator is stopped in the electric ladder shaft, and the door cannot be opened. In this case, the passenger cannot get out of the elevator shaft on his own. If the elevator has stopped, passengers should wait for rescuers to come to the rescue.

If someone tries to force open the elevator door and tries to climb the elevator shaft, they are in danger of the pole canopy opening wide, which can lead to serious injury or even death. Therefore, in the event of an elevator power outage, you should stay calm, call rescuers as soon as possible, and wait for rescue to arrive.
