The protection of electric motors in industry is a safety imperative!
What is electric motor protection?
The protection of an electric motor is essential to ensure its durability, safety, and proper functioning. Motor protections are devices that monitor and react to potentially dangerous anomalies for the motor and installation. They cover a wide range of problems, ranging from short circuits to overload.
The circuit breaker is one of the most common devices to ensure this safety. It provides automatic disconnection of the power supply in case of anomaly. For example, in the presence of currents that are too high resulting from overload or short-circuit, the circuit breaker’s tripping intervenes to stop the flow of current and protect the electric motor.
The connection of the motor also plays a crucial role. Whether it is a single-phase motor, often used in domestic applications, or a three-phase motor, more common in the industrial sector, it is imperative to have properly made and secured connections to avoid voltage imbalances or other problems.
Asynchronous motors, widely used in industry, also require special attention, especially when connected to a variable speed drive. The latter, by modulating the voltage and currents, can induce overloads if not properly calibrated or protected.
Finally, any protection system must be integrated into a well-designed electrical panel. This panel brings together and organizes all protections, allowing centralized monitoring and rapid intervention in case of anomaly.
What electrical installations require a protection device?
Electric protection is essential in any installation to protect equipment against various anomalies, overvoltage, or short circuits that could compromise their integrity or cause hazards to the user. Here are some electrical installations that require protection devices:
• Transformers: These devices convert the supply voltage from one level to another. Overvoltage can seriously damage the transformer and the devices connected to it. The transformer coils must be protected against overcurrents using specific protection devices.
• Asynchronous machine: Widely used in industry, the asynchronous motor is subject to overcurrents. Protection against overloads, often via a thermal relay, is necessary to prevent any damage to the motor. Motor ventilation is also crucial to avoid overheating.
• Electrical installation with resistors: Devices containing resistors, such as some heaters, can overheat if an overcurrent occurs. They therefore require suitable protection devices, housed in an electrical cabinet for better organization.
• Circuits with coils: Coils, present in many devices and machines, must be protected against overcurrents that could damage them.
• Installations with power electronics: These installations manage high currents and voltages. A cut-off or overvoltage can cause considerable damage. A sectioning device allows for quick disconnection in case of a problem, and an emergency stop can be used for immediate manual intervention.
• Installations requiring an electrical box or cabinet: These boxes often group several protection devices, such as differential circuit breakers. The differential is essential for detecting current leaks and triggering a quick disconnection, thus protecting people against the risk of electrocution.
• Installations requiring ventilation: To avoid overheating of certain equipment, it is essential to ensure adequate ventilation, especially when there are resistors or power electronics present.
Every electrical device or machine, big or small, requires some form of protection. Whether it is to protect against overvoltage or any other anomaly, protection devices are the last line of defense between safe operation and potential accidents or material damage. The implementation and regular maintenance of these protections guarantee the longevity and safety of any electrical system.
