ADVP-8000N Protection and monitoring device

        DVP-8000N Series digital protection and monitoring device is the main object of monitor and protection with a variety of 0.4kV ~ 110kV voltage primary equipment, it is a intelligent device with protection, measurement, control and communication, mainly suitable for protection and monitor power plant, substation and auxiliary power system of the industrial and mining enterprise.
        This series of product can not only collect to group panel, but also can be locally installed in the switch cabinet.

1. Characteristic

        The device case adopts the full close design, which is separated by strong and weak electricity. At the same time, the hardware and software redundancy design with high reliability makes the device have strong anti-interference performance.
         The device adopts a plug-in structure, each plug-in module performs a specific function, and the device can be flexibly configured to satisfy various engineering requirements.
         LCD can be switched in English and Chinese, completely menulize operation, decimalism continuous setting. The standard for LCD is 320*240 lattice,it can be real-time display of the AC analog waveform and the main wiring diagram.
         Transmission test function can be carried out for the exit loop linkage check. The local / remote switch and the open and close button on the panel can manually control the switch directly on the device.
         Perfect software and hardware self-test function. If the anomaly is found, the exit is locked, the alarm signal is displayed and the fault content is displayed.
         The device can display various protection and measurement parameters, such as current, voltage, active power, reactive power, power factor, switching state, 2~23 harmonic measurement and total harmonic distortion rate, THD.
         A high reliability, large capacity FLASH memory is used to permanently store a large number of fault events and operational records, and to store 10 recent fault record data, each recording data for 4~10 seconds. The recorded data can be displayed on the monitor, and also can be exported to the U disk. The fault waveform can be displayed by the computer software Excel, which is more convenient for fault analysis.
         The communication network adopts double Ethernet and double RS485 interface. Many devices are connected with an upper computer or a communication management machine to form a communication network for centralized control of the system, and realize the functions of remote sensing, remote control, remote control, remote sensing, etc., and the "four remote control " functions. Support the power industry standard DL/T667-1999 (IEC60870-5-103) and other communication protocols.
         All the protection functions (including non electrical protection) can select the way of exit by itself and have soft strap in service and out of service.
         All user names can be redefined themselves according to the drawings.
         The device equipped with USB interface, it can upgrade the program itself, but also can export the device parameters, protection settings, SOE events, operating records, device information table, fault recording data through the U disk, the device parameters and the protection setting values can be modified according to the derived format and then lead-in device through the U disk, so that not every device has to enter the menu setting, a lot of workload have been reduced.
         The device has a variety of functional modules including input/output expansion, operating loop, DC analog input, 4 ~ 20mA DC analog output, temperature resistance measurement,etc, it can be configured into various functions of the protection and monitor devices to meet the needs of multiple industries.
