Jh-805D microcomputer incoming line standby automatic switching protection measurement and control device
Microcomputer based protection device is an economic protection for the integration of measurement, control, protection and communication;
Tailored for the high-voltage distribution room of the distribution network terminal, with the three-stage non directional current protection as the core, equipped with the monitoring and acquisition function of power grid parameters, the traditional ammeter, voltmeter, power meter, frequency meter, watt hour meter, etc. can be omitted, and the measurement data and protection information can be transmitted to the upper computer through the communication port, which is convenient to realize distribution network automation;
According to the characteristics of distribution network power supply, the device integrates the automatic switching function of standby power supply in the device, which can flexibly realize the functions of incoming line standby switching and bus / branch standby switching.
