The equipment put into production and operation of the project advocates energy saving, intelligence, informatization, and mechanization. The company has established the Henan Triangle Energy-saving Transformer Engineering Technology Research Center, with 71 utility model patents and 15 invention patents. With years of accumulation in the transformer industry and strong technological innovation capabilities, HZEC products are sold to the Middle East, North America, South America, Europe, Southeast Asia, Africa, and other regions, covering more than 40 countries.
ZW10-12XDG/630-20 high voltage dual power supply interthrowing device (hereinafter referred to as the device) is composed of a high vacuum circuit breaker and intelligent controller two parts. It is suitable for dual power supply system with AC 50Hz, rated voltage 12KV and rated current up to 630A. When one power supply fails or undervoltage, it automatically switches to the other normal power supply to ensure the continuity of power supply. At the same time, it has the protection interlock function such as short circuit and overcurrent, which effectively avoids the unnecessary power supply shock when the load fails. When the common power supply fails, the switching device can automatically switch with the standby power supply to ensure reliability and safety. It can also be switched between the two power supplies according to the needs of the load. Especially suitable for important places where power is not allowed, as an important electrical control device to ensure continuous power supply. The product is suitable for dual power supply users who require high reliability and safety of power supply, as the control and protection Settings of dual power supply system.
Products are widely used in oil fields, mining, metallurgy, chemical industry, railway, communication, machinery and other 10KV distribution lines, 10kV lines in industrial and mining enterprises.

1. Using magnetic actuator (permanent magnet) mechanism, the parts are greatly reduced, the closing power is greatly reduced, stable and reliable, without regular maintenance. Ensure the smooth completion of the operation sequence of the recloser (t1-0.3S, t2-3S, t3-3S, locking);
2. Using imported outdoor epoxy as external insulation material, light weight, long life, good weather resistance, no oil, no SF6, in line with environmental requirements.
3. Using advanced DSP chip, set control, protection, measurement, communication in one, so that the system has advanced design, super function.
The integrated sensor technology is adopted to realize the on-line monitoring of the device.
4. Synchronous closing technology is adopted to realize synchronous closing of circuit breakers and effectively suppress operating overvoltage and inrush current.
5. Flexible communication mode, support general wireless packet service (GPRS), support Chinese and English short message;
6. Sampling up to 128 points per week and fast FFT conversion provide high speed and high precision data from fundamental wave to 19th harmonic wave for line measurement and protection.
7. With fast protection function, the distribution network can automatically isolate and restore power supply without the cooperation of the main station, which greatly improves the reliability of power supply.
8. The single-phase grounding fault can be judged online without additional configuration, and the alarm or tripping can be given according to the rule.
9. The temperature correction technology is adopted to make the device achieve high precision under various temperature conditions.
