Henan Energy Electric Equipment Co., Ltd. was established in 2011 and is an excellent and reliable transformer manufacturer in China. The company mainly develops and produces oil-immersed transformers, dry-type transformers, box-type substations and high and low voltage complete sets of equipment.The equipment put into production and operation of the project advocates energy saving, intelligence, information 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.
On-load capacitor-voltage regulating transformer is an important equipment in electric power system. it can switch between high and low voltage windings by the capacitor-regulating tap changer and switch between voltage tapping gear by the voltage regulating tap changer at the same time. Realize large, and small two rated capacity operation mode conversion and switching between different voltage taps.
1. Automatic voltage regulation, improve voltage quality: real-time detection of line voltage, according to the preset logic and algorithm, according to the line voltage fluctuations, control the tap changer to achieve automatic voltage regulation of the transformer.
2. Automatic capacity adjustment, energy saving and consumption reduction: real-time detection of the current in the line, automatically identify whether the transformer is light or heavy load operation, according to the predetermined logic and algorithm, complete the transformer capacity adjustment within 40ms; In small capacity, the no-load loss is greatly reduced to achieve the purpose of energy saving and consumption reduction.
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 query the working status of the transformer through the LCD screen or mobile APP continuously, and improve the maintenance efficiency.
5. Miniaturized design, small size, easy installation: the on-load tap-changer adopts the 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. The transformer is compact and easy to install.
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
