Description

technical field [0001] The invention relates to the technical field of withstand voltage test of electric equipment, in particular to an air-core reactor and a series air-core reactor. Background technique [0002] High-voltage withstand voltage tests are required for power equipment handover or preventive tests. During the test, an air-core reactor is used for compensation, and a capacitive voltage divider of a corresponding voltage level needs to be connected in parallel to realize voltage monitoring. In the prior art, it is often necessary to equip a voltage divider with one reactor. [0003] When conducting UHV tests, multiple reactors are often stacked in series to meet the requirements. The corresponding capacitive voltage divider needs to be set up at the same time as the reactor is set up, which makes the preparation work before the test and the finishing work after the test time-consuming and laborious. And the voltage divider will occupy a large part of the test ...

AI Technical Summary

Problems solved by technology

It is necessary to set up the corresponding capacitive voltage divider at the same time as the reactor is set up, which makes the preparation before the test and the finishing work after the test time-consuming and laborious.

And the voltage divider will occupy a large part of the test site, which will bring inconvenience to other work

In addition, due to the existence of the voltage divider, it is not conducive to the vehicle-mounted, platform-based, and centralized equipment
