Strip-type No-excitation Tap Changer
This range of tapping switches is specifically designed for oil-immersed transformers operating at a frequency of 50Hz and rated voltages of 35kV or lower. To effectively regulate voltage, it is essential to ensure the transformer is disconnected from the coil and modified under no-load conditions. This approach enables precise voltage regulation, allowing for optimal management of secondary-grade output voltage. Enhance the performance of your transformer systems with these reliable tapping switches, tailored for efficiency and safety in voltage adjustment.
Liaoning Jinli Electric Power Electrical Appliance Co., Ltd was established in 1986. It was a specialized manufacturer of transformer tap changers designated by the former Ministry of Machinery Industry and Ministry of Electric Power Industry of China. It was one of the earliest enterprises in China to enter this field.
The company specializes in the research and development, production and service of on-load and off-load tap changers. It currently offers more than 30 series and over 5,000 specifications of products which can meet the needs of various power grids and transformers, and also undertakes the design and manufacturing of special type tap changers. As one of the earliest domestic manufacturers with independent intellectual property rights for intelligent capacity-regulating on-load tap changing technology, this series of products has filled domestic gaps and reached international advanced levels. Its sales network covers the whole world, and maintains long-term cooperation with many well-known enterprises, and its products are exported to more than 30 countries and regions.
The principle of operation
Driven through the handle from rotating rack body movement, led moving contacts horizontal rack to change the tap position of the switch, thereby changing the transformer primary winding turns, to change the transformer changes, adjust the secondary voltage of purpose.
Caution for operation
- 1 Use of environmental temperature: in air -25 ℃ ~ 40 ℃, in oil -25 ℃ ~ 100 ℃.
- 2 Installation places should not be explosive and corrosive gases.
- 3 Before tap-assembled, be sure to check whether the tapping switch could meet the transformer type requirements, so as to avoid unnecessary losses.
- 4 Transformer tap lead can not be too short, and eliminate the lead tension in the assembly, so as to avoid switching operation of the insulating rod deformation lead to poor contact and torque too large.
- 5 Tap changer should be on the 105℃ ±5 ℃ oven to dry transformers with the body of 24 to 48 hours to dehumidify before installed and use. If find oil leakage along the shaft, tighten the stopper. If the oil leaks along the transformer lid, tighten the round nut.
- 6 When the tap changer at the ultimate position, it’s prohibited to operate control to the ultimate direction.
- 7 After tap changer was dried, please drop the transformer oil on static contact and moving contacts then rotary switches. rotate back and forth the tap 5～8 times before assembly.
