National New Year folks Hello everyone, I 宁浩博 mining company Ji Machinery Co., Ltd. with its strong technology, excellent product quality, satisfactory service, in the market enjoy a high reputation. Intelligent integrated protection with excellent quality, trusted by the user. First-class products, good service is our consistent aim! The company is willing to friends and the community work together for common development! The staff warmly welcome the global community of companies and individuals to negotiate business for a better future! You have any questions about the company and products need advice, you can call the telephone company and we look forward to your sincere cooperation. Let me take you to understand this product: PIR-800II Feed Switch Intelligent integrated protection device is the first to make a successful design for explosive gas (methane) and coal dust coal mine intelligent multi-functional integrated protection , with 380V, 660V, 1140V voltage level, the maximum current up to 1000A of the various models of feed switch supporting the use, in order to achieve a variety of protection and control functions of the above power supply system. Protector uses an advanced microprocessor and infrared remote control technology, high-precision data processing and advanced protection algorithm has the advantage of protecting high precision, fast response and so on. This protection can be achieved total leakage protection switch, (sub-switch selective leakage protection), leakage lockout, overload, short circuit, phase imbalance (including off-phase), under voltage, fault finding, testing, wind power, gas, telecommunications, etc. protection features. Uses an advanced dual-processor, DSP and AVR chip precision data processing and advanced protection algorithms enable fast and accurate response rate. Performance than the previous generation has significantly improved protection. Equipped with RS-485 communication interface, can not afford to frame a more reliable and stable transmission. You can achieve remote adjustment, remote, remote control, telemetry. EMC electromagnetic interference by the highest level, completely avoiding the garbled, black, black and white. Added a new feature to avoid phase-sensitive protection malfunction when the motor starts, while protecting long-distance short-circuit fault, the other can make a substantial decline in the value of the switch setting, can accurately distinguish between short-circuit and over 3000 meters high current power supply terminal equipment overload. Plus. Mature technology advanced, high integration, excellent technology, and easy to maintain. Is our latest generation of products, to make up for the previous lack of protection of all kinds, (another split to choose from, as shown). Is recommended to increase the power factor, power measurement, error is less than six thousandths of. Provide multiple sets of custom backup node interface, more fully meet the needs of individual users. (Standby switch 3 has been used) the first real-time information observation window, the switch can collect all relevant data, you can display the zero sequence current and zero sequence voltage and other data in order to provide an accurate valuation of the various settings based on rights: namely switch factories, Lead Engineer, Field Operator Menu, targeted setup requirements. At the same time all protection functions are completed by adjusting the software using Chinese LCD display, with menu-driven man-machine interface, easy operation. Displays the current time, three-phase current and grid voltage, active power, power factor, insulation resistance (master switch or sub-gate), temperature, gas concentration, wind blocking, running status (open / close), and run-time error message is displayed Information is extremely rich. ??????? PIR-800II feed Intelligent integrated protection device for my company's second-generation for Mine Feed Switch intelligent protection device, covering 380V, 660V, 1140V voltage rating, 5 ~ 1000A rated current, full Digital tuning. With undervoltage | overvoltage | overload | short circuit (phase-sensitive) | Unbalanced | break with | Wind Power | Gas | close circuit voltage monitoring | power level measurement | Temperature protection | leakage blocking | leakage protection | selective leakage protection function; with four remote RS485 communication function; with fault memory and inquiries; with test functions via the menu.
