HZYA-2Z Digital Transformer On Load Switch Tap-Changer Analyzer

I.Description

The on-load tap-changer is the only moving part connected to the transformer circuit. Therefore, its detection has become increasingly important. According to the "Power Equipment Transfer and Preventive Test Procedures," it is required to check the on-load tap-changer action sequence and measure the switching time.

This instrument is primarily used to measure the transition waveform, transition time, instantaneous transition resistance, and three-phase synchronization of the transformer on-load tap-changer.

The instrument features a high degree of intelligence, with all-English menu prompts for simple operation. It is compact, lightweight, and offers strong anti-interference capability, significantly reducing the labor intensity of field personnel. It is an ideal instrument for ensuring safe production and improving product quality in power supply units and transformer manufacturing industries.

Handling Instruction

Matters needing attention in operation:

Before use, the grounding terminal of the instrument must be connected with the ground wire.

During the test, it is not allowed to dismantle the test line.

For the on-load switch that has not been moved for a long time, the switch should be changed several times before the test to remove the oxide layer and impurities on the contact surface.

With our own rapid development and efficient operation, we have played an active role in promoting the Transformer on-Load Tap Changer Oltc Diagnosis Testing Equipment industry. The emergence of a large number of new technologies, new methods and new processes has accelerated the speed of product renewal and shortened the life cycle. We have plans and targets to provide various training and learning and growth opportunities for our employees, including professional skills for each position and general management skills.
