Description du produit

I. Positionnement du produit de base

Le relais de protection et de commande de moteur ABB REM620A_F NAMBBABA33E5BNN1XF est un dispositif de protection et de commande intelligent spécialement con?u pour les moteurs industriels moyenne et haute tension (1kV - 35kV). Il est hautement compatible avec les équipements moteurs clés tels que les pompes, les ventilateurs, les compresseurs et les laminoirs dans les industries telles que le pétrochimie, l'électricité, la métallurgie et l'exploitation minière. En intégrant des fonctions de protection complètes, une surveillance précise de l'état et une logique de commande flexible, il peut couper rapidement l'alimentation pour éviter les dommages à l'équipement lorsque le moteur rencontre des défauts tels que la surcharge, le court-circuit et le blocage du rotor. En même temps, il collecte les données de fonctionnement en temps réel du moteur et prend en charge l'entretien prédictif, servant ainsi de composant électrique de base pour garantir le fonctionnement s?r, efficace et à long cycle des moteurs industriels.

II. Fonctions de protection de base et avantages1. Protection contre les défauts en tout scénario, couvrant l'ensemble du cycle de fonctionnement du moteur

Protection de base contre la surcharge: Adopte une courbe de surcharge inverse (conforme à la norme IEC 60947 - 4 - 1). Le multiple de surcharge (1.05I? - 8I?) et le temps d'action peuvent être configurés de manière flexible en fonction du courant nominal du moteur (I?), s'adaptant aux caractéristiques thermiques de différents types de moteurs (par exemple, les moteurs asynchrones à cage d'écureuil et à rotor bobiné) et évitant la combustion des enroulements causée par une surcharge prolongée du moteur. Il dispose également d'une fonction d'alarme préalable de surcharge, qui émet une alarme lorsque la charge atteint 5% - 10% en dessous du seuil de protection, laissant du temps de traitement aux personnels d'exploitation et d'entretien.
Protection contre le court - circuit et le fonctionnement anormal:

Protection contre le court - circuit: Le courant d'action instantané peut être réglé à 2I? - 10I?, avec un temps d'action de <50ms, quickly cutting off short-circuit faults to prevent fault expansion.
Locked rotor protection: Triggers protection within 1-5 seconds when a sudden drop in motor speed (accompanied by a sudden increase in current) is detected, applicable to scenarios such as pump jamming and fan impeller seizing.
Phase loss/unbalance protection: Monitors the three-phase current unbalance degree in real time (adjustable from 0% to 50%). When one phase is lost or the difference between three-phase currents exceeds the limit, it acts with a delay of 0.5-10 seconds, avoiding winding overheating caused by motor operation under phase loss.
Earth fault protection: Supports residual current-based (compatible with zero-sequence CT) or additional DC-based earth detection. The protection current is adjustable from 0.1A to 10A, with an action time of <100ms, effectively preventing insulation damage caused by motor winding grounding.

Special working condition protection:

Under-voltage/over-voltage protection: The voltage monitoring range is 60%-120% U?, and the action time is adjustable from 1 to 60 seconds. It adapts to power grid voltage fluctuations, preventing motor overload under low voltage or insulation breakdown under high voltage.
Long startup time protection: Sets the allowable startup time of the motor (5-60 seconds). If the current does not drop below the rated value during startup, the power supply is automatically cut off to prevent locked rotor or startup circuit faults.
Thermal memory function: Retains motor thermal accumulation data after power failure (memory time adjustable from 0 to 30 minutes), avoiding cumulative overheating caused by frequent motor startup and shutdown, which conforms to the actual needs of motor thermal protection.

2. High-Precision Monitoring and Condition Analysis

Multi-dimensional data collection: Collects real-time key parameters including three-phase current (accuracy ±0.2% FS), three-phase voltage (accuracy ±0.2% FS), power factor, active/reactive power, winding temperature (compatible with PT100/RTD sensors, accuracy ±0.5℃), and bearing temperature. The sampling frequency reaches 10kHz, enabling capture of transient states such as motor startup and sudden load changes.
Trend analysis and early warning: Built-in data recording function (storage capacity ≥1000 event records, including waveform data 10 seconds before and 5 seconds after a fault). It supports trend curve analysis of parameters such as current and temperature (cycle adjustable from 1 minute to 1 hour). When parameters deviate from the normal range (e.g., continuous current rise or slow temperature increase), preventive early warnings are triggered, helping to shift from "fault repair" to "predictive maintenance".
Motor health assessment: By continuously monitoring motor vibration (requires external vibration sensor), insulation resistance (requires external insulation monitoring module), air gap magnetic field, and other data, combined with ABB's patented motor health algorithm, it generates a health status score ranging from 0 to 100. This score intuitively reflects potential issues such as motor insulation aging and bearing wear, extending the motor's service life.

III. Flexible Control and System Integration Capabilities1. Diversified Control Logic and Operation Modes

Control mode adaptation: Supports multiple startup methods such as direct startup, star-delta startup, auto-transformer reduced-voltage startup, and soft starter/inverter linkage. It can control executive components such as contactors and circuit breakers through relay outputs (8 channels of DO, capacity 5A/250V AC), meeting the startup needs of motors with different powers (10kW-1000kW).
Local and remote control: Equipped with 2 RS485 communication interfaces (supporting Modbus RTU/ASCII and IEC 60870-5-103 protocols), it can be connected to DCS and SCADA systems to realize remote startup/shutdown and parameter configuration. It also has a built-in LCD display panel (128×64 pixels, with backlight support) and 4 operation buttons, supporting local manual control and parameter setting, and adapting to both unattended and on-site operation scenarios.
Logic programming function: Built-in configurable logic controller (CLC), supporting graphical programming (no code required) to customize control logic (e.g., motor startup/shutdown interlock, linkage control with other equipment). It can configure up to 32 logic blocks, adapting to motor control needs in complex industrial processes (e.g., standby switching of pump sets, sequential startup/shutdown of fans).

2. Strong Environmental Adaptability and Reliability Design

Industrial-grade hardware protection: Adopts a die-cast aluminum alloy housing, with an protection rating of IP54 (panel-mounted) / IP40 (cabinet-mounted), resisting dust and humid environments. The operating temperature range is -25℃~+70℃, and the storage temperature range is -40℃~+85℃, enabling stable operation in harsh scenarios such as chemical workshops, underground mines, and power plant turbine rooms. It has passed EN 61000-6-2 (industrial environment immunity) and EN 61000-6-3 (emission, Class B) electromagnetic compatibility tests, with no misoperation under strong electromagnetic interference such as high-voltage equipment startup/shutdown and inverter operation.
Redundancy and fault self-diagnosis: Supports dual-power redundant input (24V DC/110V AC/220V AC optional, automatic switching), ensuring reliable power supply for the device itself. It has hardware fault self-diagnosis functions (e.g., CPU, memory, and I/O module fault detection). When a fault occurs, it issues a clear alarm through LED indicators and messages, and automatically switches to "fail-safe mode" (e.g., maintaining output status or cutting off non-critical outputs) to avoid secondary risks.
