TC-3071 backup power source from the drop device

The main functions of the backup power supply device TC-3071 are introduced

Main features of TC-3071 backup power supply device

       1. TC-3000 substation integrated automation system adopts hierarchical and distributed system structure，At an interval，With a set of device design，The device can be centrally assembled or dispersed on the high voltage switchgear，Each interval functions independently，The devices are connected only by a network，Information sharing，This makes the whole system not only flexible，And its reliability has also been greatly improved，The failure of any one device affects only one local component。

       2. The TC-3071 backup power generator uses A high-performance processor (ARM M3) and A high-resolution A/D converter，Wave 32 sampling points per week，At the same time, it can complete real-time protection, measurement, harmonic analysis, low frequency load reduction protection, small current grounding line selection, switching accident statistics and other complex functions。

       3, the protection function is completely independent of the communication network, network breakdown does not affect the normal operation of protection。

       4, in terms of hardware design, all devices use a unified hardware platform, which brings great convenience for debugging and maintenance, and the device still retains the independent input and output loop and operation loop of the traditional microcomputer protection。

       5, TC-3071 backup power source transmission device adopts hierarchical distributed system is an important factor to improve the reliability of the whole station，In particular, the function is independent from the communication network of the transformer protection，Line protection，Feed line protection,Capacitor protection,Independent configuration of motor protection and other devices at various intervals，It is a prerequisite for the safe and stable operation of substation。

       6, TC-3071 standby power source input device adopts a fully sealed design, coupled with well-designed anti-interference components, so that the anti-vibration ability, anti-electromagnetic interference ability has been greatly improved。

       7. The protection current loop and the measurement current loop of the TC-3071 backup power supply device are set separately, respectively from different current transformers, and are designed with dual watchdog functions of hardware and software, so that the whole system has high measurement accuracy and anti-interference ability at the same time。

       8, friendly man-machine interface, the device adopts the whole Chinese large-screen LCD display, trip report, alarm report, remote message, telemetry, set value setting, etc. have clear Chinese characters on the LCD, easy for users to use and master。

       9, the communication mode adopts 485 port, that is, the controller area network interface，Its characteristics are: simple structure，There are only two wires connected to the outside;Transmission speed up to 9600;Transmission distance up to 1KM;CRC testing is adopted and error handling capability can be provided.Using non-destructive bus arbitration technology，The station communication has high efficiency and anti-interference ability。
