What is the control cabinet in an elevator?
An elevator control cabinet is an electrical control device housed in a cabinet structure that provides safety protection. It is used to control the operation of the elevator and serves as the electrical and signal control center of the elevator. The main functions of the elevator control cabinet are operational controlling and drive controlling. Generally, it is placed in the elevator machine room, but for machine-room-less elevators, the control cabinet is installed in the shaft.
The main components in an elevator control cabinet include: elevator control boards or controllers, transformers, bridge rectifiers and capacitors, air switches or fuses, relays and contactors,frequency inverters, power cables, signal cables, terminals, or connectors. Traditional elevator control boards mainly use PLCs (Programmable Logic Controllers), which are essentially microcomputers. But Modern elevators generally use integrated controller cabinet, which hold the highest market share. The advantages include: Delicate and refined appearance, versatile installation options, and natural integration with architectural and interior design styles；Integrated design with deep integration, with the control cabinet’s volume being only 30% of traditional control cabinets.
Home Villas Elevator Control Cabinet Installation Principles
The noise from the control cabinet of a home elevator mainly comes from the operation of the elevator and the engagement of various contactors. If the control cabinet position is too close to a room, it may cause elevator noise. For villas with a dedicated equipment room, the control cabinet can be placed in the equipment room, but it should ideally be within 10 meters of the shaft. The control cabinet should be kept about 5 meters away from the main machine to avoid affecting signal transmission.
There might also be concerns about whether the control cabinet of a home elevator emits radiation and if it is harmful to humans. The control cabinet mainly emits electromagnetic radiation. Most control cabinets have some level of radiation, but it is not harmful to humans because the metal casing can shield most electromagnetic waves, and it is grounded. The radiation is generally smaller than that of a mobile phone, so there is no need to worry.
