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.
The wide on-load high-voltage distribution transformer is a kind of transformer that can complete the tap voltage switching in the load operation, it belongs to a kind of on-load regulating power transformer. The main function of this kind of transformer is to transfer alternating voltage and current by changing the alternating current according to the law of electromagnetic induction. The main parameter of a wide-range on-load high-voltage distribution transformer is the rated capacity. is a common value expressing the power. is used to represent the amount of transmitted electric energy. is usually expressed in kVA or MVA. When a rated voltage is applied to a transformer, is used to determine the rated current that does not exceed the temperature rise limit under specified conditions.
1. Multi-gear, wide voltage regulation :9 gear voltage regulation position, voltage regulation range support ±10% and ±20% two options;
2. Transformer primary and secondary fusion: In addition to automatic voltage regulation, it also expands the monitoring of the transformer operating state (current, voltage, oil temperature, oil pressure, etc.), and realizes the primary and secondary fusion of the transformer.
3. Support GPRS wireless communication and RS485 serial communication, to achieve remote monitoring transformer operating status, view and modify parameter values and other functions, to achieve the automation of the distribution network station area;
4. Good man-machine interface: The controller is equipped with an LCD screen with Chinese display and built-in WIFI module, which is convenient for maintenance personnel to check the transformer working status through the LCD screen or mobile APP continuously, and improve the maintenance efficiency;
5. Miniaturized design, small volume, easy installation: the on-load tap-changer adopts a combined structure to achieve miniaturized design, the switch is installed on the whole, there is no independent oil chamber, the vacuum tube arc extinguishing, simple structure, compact transformer volume, easy installation.
6. Maintenance-free long life: no oil filter is required during operation, no regular maintenance is required, the tap-changer electrical life reaches 50,000 times, and the mechanical life reaches 100,000 times.
