Elevator Control Cabinet

The operation of the elevator depends on the delicate harmony between different parts, each part carries a special indispensable function. Among those important components, the elevator electrical cabinet or elevator control cabinet plays an important role, raising the question of its task and position in the elevator operating system.

Let's join and discover the answer in the article of SANKYO Elevator below to better understand this component.

THE IMPORTANCE OF ELEVATOR ELECTRICAL CABINETS

Elevator electrical cabinet is also known as elevator control cabinet , which is the heart of the elevator system , responsible for controlling all activities to ensure the elevator operates stably.

The quality of the electrical cabinet has a direct impact on the performance of the elevator. When the elevator operates stably, the elevator electrical cabinet also ensures the smoothest and safest operation. Figuratively speaking, the elevator electrical cabinet can be seen as the brain of the system, the source of energy that helps the elevator to fully develop its value and benefits.

The quality and performance of the elevator electrical cabinet play an important role in the operation of the elevator equipment . When the elevator electrical cabinet is selected with quality products, the elevator will operate smoothly and maintain in ideal operating condition.

On the contrary, choosing a poor quality elevator control cabinet can lead to frequent breakdowns, problems such as incorrect floor stops, floor calls without response, and sometimes serious problems such as free fall, brake failure, causing danger to users. Choosing a quality electrical cabinet is a key factor to ensure safety and stability in elevator operation.

ELEVATOR ELECTRICAL CABINET STRUCTURE

The structure of the elevator electrical cabinet is very complex, merging from many different small parts.

Elevator electrical cabinet controller

The elevator control cabinet is an important part of the elevator control cabinet, forming the main control system. When receiving the floor selection signal, the control system processes the information and brings the elevator to the correct floor. Therefore, any error occurring in the control system will directly affect the operation of the elevator. This system in the elevator control cabinet is divided into two types to serve specific purposes:

• Single control system : Specially designed for installation on a single elevator, the single control system is suitable formini elevators,home elevatorsor small-scale elevator projects.

• Group elevator control system :Usually applied to a group of adjacent elevators,elevator control systemsare popular in residential areas, commercial centers, hotels, hospitals, and large-scale projects. This system requires high technology and engineering due to the complexity of the group elevator operation process.

Elevator electrical cabinet voltage and efficiency conversion control system

This unit is responsible for regulating and executing commands from the elevator operating system . By transforming voltage, the elevator controller distributes current to the drive components, increasing the efficiency and precision of the operating system.

Elevator opening and closing time regulation system

This part of the elevator electrical cabinet is responsible for regulating the opening and closing times based on parameters previously set by the user. It provides the ability to flexibly adjust the elevator's operation according to specific requirements.

Elevator door control

This part plays a role in processing information related to the opening and closing of the elevator door, directly connected to the photocell (infrared sensor) installed at the elevator cabin door. This helps ensure that the opening and closing process of the elevator door is more accurate and smoother. In addition, thanks to the infrared sensor, the elevator is able to detect obstacles at the door, helping to avoid jamming and increase safety for users.

Elevator safety system

The safety system in the elevator electrical cabinet includes two important devices: the rescue system and the travel limit switch .

The elevator rescue system is activated when the elevator experiences a sudden power failure. This device uses a stored power source, similar to a battery or UPS. In the event of a sudden power failure, the rescue system will automatically activate, providing backup power to ensure the elevator continues to operate. However, this backup power source can only be used for a limited period of time and cannot completely replace the power source from the grid.

Elevator travel limit switches play an important role in protecting users. This device helps the elevator cabin maintain a safe distance from the elevator pit when the elevator is over speed. Each elevator is usually equipped with 2-3 travel limit switches to ensure maximum safety.

COMMON TYPES OF ELEVATOR ELECTRICAL CABINETS

Elevator electrical cabinets are diverse in operating principles and origins. Below are some common types of electrical cabinets used for passenger elevators.

Classification by elevator operating principle

Currently, the control cabinets used for elevators are divided into two main types: elevator control cabinets using ACVV operating system and elevator control cabinets using VVVF operating system. Each type of electrical cabinet has its own unique characteristics, suitable for the specific requirements of each project.

Note: The choice between VVVF and ACVV depends on specific project requirements, budget, and desired performance and user experience.

Classification by state of readiness for operation

In the current market, there are two main types of elevator electrical cabinets : imported electrical cabinets and assembled electrical cabinets. Both of these types are characterized by their own advantages and disadvantages, as well as different qualities.

WHERE IS THE ELEVATOR CONTROL CABINET INSTALLATION LOCATION?

Depending on the structure of the project, the location of the elevator control cabinet will be determined for convenience and ease of operation during maintenance and repair by technical staff. This helps to optimize the performance and utility of the system.

For elevator control cabinet with cabin

For elevator control cabinets with machine rooms , the most ideal location is at the top of the building. This is because the control machine room is often large in size, placing it at the bottom can create obstacles in movement and affect the aesthetics of the building. The location at the top helps the control cabinet to be hidden inside the machine room, the space below is kept convenient and the beauty of the architecture.

For elevator control cabinet without cabin

In the case of buildings with limited height and area, the construction of elevator machine room becomes difficult. In such buildings, depending on the specific characteristics, the elevator electrical cabinet can be located in front of the top floor or outside the elevator to optimize space and ensure reasonable layout.
