工作原理

MIVII1000E00HI00 频率继电器根据设定的频率范围，对电网中的频率进行监测。当电网频率超出或低于设定的频率范围时，继电器会触发保护、控制相应的设备或发出警报信号，以保证电网运行的安全和稳定。具体来说，频率继电器的工作流程如下：

采样与输入：MIVII1000E00HI00频率继电器首先采样到电网的环境频率，并将这个信号输入到电路处理单元。

处理与比较：电路处理单元会根据预设的电网工作条件来计算电网的频率，并与预设的频率范围进行比较。

输出控制：如果电网频率超出或低于预设范围，处理单元会触发输出单元发出控制信号或报警信号。

MIVII1000E00HI00频率继电器的动作原理主要基于振荡器的原理，通过振荡电路、比较电路、计数电路和输出驱动电路等部分实现。当继电器工作时，它会捕捉到被跟踪电源的电压变化，并通过振荡电路将这些变化转换为单一的频率，再经过比较电路与设定值进行比较判断，最终根据判断结果输出相应的控制信号

Working principle

The MIVII1000E00HI00 frequency relay monitors the frequency in the grid according to the set frequency range. When the power grid frequency exceeds or falls below the set frequency range, the relay will trigger protection, control the corresponding equipment or issue an alarm signal to ensure the safety and stability of the power grid operation. Specifically, the frequency relay workflow is as follows:

Sampling and input: The MIVII1000E00HI00 frequency relay first samples the ambient frequency of the grid and inputs this signal to the circuit processing unit.

Processing and comparison: The circuit processing unit calculates the frequency of the grid according to the preset operating conditions of the grid and compares it with the preset frequency range.

Output control: If the grid frequency exceeds or falls below the preset range, the processing unit will trigger the output unit to issue a control signal or alarm signal.

The operation principle of MIVII1000E00HI00 frequency relay is mainly based on the principle of oscillator, through the oscillation circuit, comparison circuit, counting circuit and output drive circuit. When the relay works, it will capture the voltage changes of the tracked power supply, and convert these changes into a single frequency through the oscillation circuit, and then compare the circuit with the set value for comparison and judgment, and finally output the corresponding control signal according to the judgment result
