Product Description

Product Description

Oil-immersed test transformer, also known as booster, is a basic test equipment for power stations, power supply and distribution systems, scientific research institutions and other users. It is used to conduct insulation strength tests on various electrical products, electrical equipment, insulation materials, etc. at specified voltages, to assess the insulation level of the products, to find insulation defects in the tested products, and to measure their ability to withstand overvoltage.

The AC/DC dual-purpose light high-voltage test transformer is made of high-quality cold-rolled silicon steel sheets. The coil is a concentric pagoda-shaped multi-layer cylindrical type, with the low-voltage coil inside and the high-voltage coil outside; the shell is portable, with the advantages of small size, light weight, beautiful appearance, and easy movement.

Working method:

Use the industrial frequency 220V (380V for 10KVA and above) power supply to connect to the control box (set) (it is a supporting equipment for the test transformer, please refer to the instruction manual of the control box (set) for detailed information), and adjust the 0-220V/380V voltage through the auto-voltage regulator to input it into the primary winding of the test transformer. According to the principle of electromagnetic induction, the secondary (high voltage) winding obtains the same multiple of the voltage amplitude according to the ratio of its number of turns to the primary winding - industrial frequency high voltage. This industrial frequency high voltage can be rectified by the high-voltage silicon stack and filtered by the capacitor to obtain DC high voltage, where the amplitude is times the effective value of the industrial frequency high voltage.

This series of products is divided into three categories: AC type, AC/DC dual-purpose type, and the connection with a 200V tap can be connected into a series-excited test transformer.
