Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric reactor testing, and particularly relates to an electric reactor pressure resistance testing machine and method. BACKGROUND

[0002] An electric reactor, also known as an inductor, is an electrical element with a winding as a core conductive component and a core (or air magnetic circuit) as a magnetic coupling medium. Based on the principle of electromagnetic induction, the electric reactor hinders the mutation of current in an alternating current circuit (passes direct current, blocks alternating current, passes low frequency, and blocks high frequency) by generating inductive impedance, to realize functions such as current limiting, filtering, reactive power compensation, and electric energy transmission.

[0003] In order to simulate the extreme overvoltage caused by lightning strikes and operations that the electric reactor may encounter in operation, so as to strictly test the strength and reliability of the main insulation system (including winding-to-ground and phase-to-phase) of the electric reactor, the electric reactor needs to be subjected to pressure resistance testing (also known as voltage resistance testing).

[0004] The patent with the authorized publication number CN120177201B discloses an electric reactor pressure resistance detection device, which comprises a base and a mounting table mounted on the end face of the base. The mounting table is used for mounting the electric reactor. The end face of the base is fixedly provided with a control cabinet. The device further comprises two detection seats arranged on the upper sides of the base.

The base is provided with two driving mechanisms for driving the two detection seats to move towards each other. The interiors of the two detection seats are provided with a plurality of U-shaped cavities, which are in communication with each other. The device can make the electric reactor insulation sleeve pressure resistance detection results more in line with the actual situation, and can pre-select the points that may have strength defects, improve the representativeness and detection efficiency of the detection results, and expose potential cracks and other defects before detection, thereby reducing the possibility of defect omission.
