ABB 3ASC25H705-7

这是ABB ACS800和ACS880系列工业变频器的制动斩波模块。其主要功能是消散逆变器驱动电机发电时产生的再生能量，防止逆变器直流母线电压过冲，从而保护逆变器并确保系统稳定运行。

产品名称和类型
产品名称：制动斩波器模块

型号：3ASC25H705-7

系列：ABB ACS800 / ACS880 驱动系统配件

常见别名：制动单元、刹车单元

主要功能及原理
功能：

能量释放：在电机动态制动期间（例如降低负载或使风扇或泵滑行），电机变成发电机，将机械能转换为电能并将其反馈到逆变器的直流母线中。

电压钳位：实时监控直流母线电压。当电压超过预设的安全阈值（例如 720V DC）时，斩波器自动开启。

逆变器保护：该模块将多余的能量引导至外部制动电阻，将其转化为热量并散发出去。这可以防止过高的直流母线电压导致逆变器报过压故障（例如 F0004）甚至损坏。

原则：

该模块与逆变器的直流母线（+DC 和 -DC）并联。

其核心是一个大功率IGBT（绝缘栅双极晶体管）开关。

当检测到总线电压过高时，控制电路采用高频（“斩波”）方法快速打开和关闭IGBT。

IGBT导通，将外部连接的制动电阻连接至直流母线电路。能量流经电阻并转化为热量耗散。

通过调整IGBT的开/关时间比（占空比），可以精确控制制动扭矩和总线电压水平。

主要特性和参数
适用驱动器系列：

ACS800

ACS880

Rated Voltage: Suitable for drives with 380-480V AC three-phase input (corresponding to a DC bus voltage of approximately 540-680V DC).

Maximum Continuous Braking Power: This depends on the power of the connected external braking resistor. The chopper module itself specifies the maximum current it can safely switch.

Peak Braking Power: Also dependent on the external braking resistor, allowing for short periods of time with loads higher than the continuous power rating.

Control: Automatic switching control based on the DC bus voltage.

Mounting:

Built-in: Mounts directly in the cabinet or power unit of certain ACS800/ACS880 drive models as an integrated option.

Wall-mount: Can also be mounted separately on the backplane of a control cabinet.

Connections:

Power Supply: Connects to the positive and negative DC bus terminals (+DC, -DC) of the drive via busbars or cables.

Load terminal: Output terminals for connecting an external braking resistor.

Control signal: May include status feedback signal lines.

Typical Application Scenarios
This module is widely used in applications requiring rapid deceleration or where gravity loads are present, including but not limited to:

Material handling: Cranes, hoists, elevators, and winches (when lowering heavy objects).

Centrifuges: Industrial centrifuges and dehydrators.

Conveyor systems: Inclined conveyors.

Fans and pumps: Rapid stops due to pipeline pressure or fluid inertia.

Machine tools: Rapid braking of spindle motors.

Test benches: Load testing of drive systems.
