Abstract ： In recent years , The continuity of industrial production has become the focus of many enterprises , So that a large number of new projects need anti-seismic circuits at the beginning of design . This paper introduces a new chemical industry group in Hebei Province 30 10000 ton functional polystyrene project , use ARD2F Motor protector and ARD-KHD-S03A The anti surge device can protect the motor circuit and restart the motor after voltage loss , Guarantee the service life of motor equipment , At the same time, it can reduce the production stagnation caused by voltage drop , Reduce maintenance labor costs .
1、  Description of project
Hebei Yijia Chemical Co., Ltd. was established in 2021 year 1 month , It's the county 2021 Invested and constructed in 9 One of the demonstration projects , The project covers an area of 85.75 mu , investment 2.5 One hundred million yuan , It is mainly used to produce functional polystyrene and other polymers , The planned annual production capacity is about 30 Ten thousand tons of .
2、  Product scheme and function
ARD2F Intelligent motor protector and ARD-KHD-S03A The anti-seismic device is installed in the project of Chemical Co., Ltd 139 On a motor circuit .
ARD2F Protector 、 Protect 、 Control and communication network at the same time ,ARD2F The protector passes through the built-in capacitor , Supply power to the protector in case of electric shock . After voltage recovery and contactor automatic suction , The output of the protector relay can be maintained for a period of time （0.0-10.0s Adjustable ）, Otherwise, it will enter the restart phase , Recover the voltage within the preset allowable time , The start relay will delay closing , Thus, the motor can be restarted .
When the frequency conversion circuit adopts ARD-KHD-S03A Anti shake device , The device uses frequency conversion to start the intermediate relay signal 、 Frequency converter EROR Signal and operation signal , It will first judge the current status of earthquake electricity through the voltage . When the voltage recovers to the restart voltage within the set time , Output the restart signal to the frequency converter , Restart it . If the frequency converter EROR The signal is present when the voltage is restored , Then the device frequency conversion is reset DO Output 、 Reset the inverter fault 、 Restart signal after restart delay .

The specific configuration table of the project is as follows ：
