Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage testing of rotary transformers, and more precisely, to a high-voltage testing device for rotary transformers. Background Technology

[0002] A rotary transformer is a type of induction micro-motor, commonly used to measure the angular displacement and angular velocity of rotating objects. A rotary transformer consists of a stator and a rotor. The stator windings, acting as the primary winding, receive the excitation voltage, while the rotor windings, acting as the secondary winding, generate the induced voltage through electromagnetic coupling. As a precision angle, position, and speed detection device, the rotary transformer is suitable for all applications using rotary encoders, especially in environments with high temperatures, extreme cold, humidity, high speeds, and high vibrations where rotary encoders cannot function properly. Rotary transformers are widely used in servo control systems, robotic systems, machine tools, and other technical fields.

[0003] Because rotary transformers require high precision, they need to be tested before leaving the factory. High-voltage testing first requires connecting the grounding probe assembly to the rotary transformer, and then connecting the test probe assembly to the rotary transformer to perform the high-voltage test. Currently, the testing equipment used for high-voltage testing of rotary transformers requires replacing the entire set of test probe assemblies for rotary transformers with different outer diameters, which is time-consuming and affects production efficiency.

[0004] In summary, there is a need in the field for a high-voltage testing device for rotary transformers that can be adapted to different products without changing the test probe assembly. Utility Model Content
