一种无功补偿用磁保持继电器的试验设备研究

Research on a Test Equipment of Magnetic Latching Relay for Reactive Power Compensation

设计了一种适用于无功补偿用磁保持继电器的试验设备。该设备具备接通设定和分断设定等功能,即可控制触点的接通相位角及触点是否过零分断。试验过程中,软件界面可显示和保存触点接通瞬间电压波形、峰值电流和磁保持继电器的动作时间等记录。

A test equipment for magnetic latching relays used for reactive power compensation was designed.It has functions such as make setting and break setting,which can control the making phase angle of the contact and whether is on zero phase angle when the contact breaking.During the test,the software interface can display and save the voltage waveform,peak current and the action time of the magnetic latching relay at the moment of contact connection.
