Abstract

The invention discloses a wireless frequency conversion resonance withstand voltage testing device and a testing method thereof. The device comprises a handheld manipulator, a frequency conversion controller and an external loop. The handheld manipulator is in wireless connection with the frequency conversion controller, and the external loop is connected with the frequency conversion controller. The handheld manipulator comprises a first wireless receiving and dispatching module, a first touch terminal and a storage battery. The first touch terminal receives test setting parameters input by testing personnel, and the test setting parameters are sent to the frequency conversion controller through the first wireless receiving and dispatching module. The frequency conversion controller comprises a second wireless receiving and dispatching module, a frequency converter and a second touch terminal. The second wireless receiving and dispatching module receives the test setting parameters sent by the first wireless receiving and dispatching module and forwards the test setting parameters to the frequency converter, and the frequency converter controls the external loop according to the test setting parameters so that a withstand voltage test can be made. According to the wireless frequency conversion resonance withstand voltage testing device and the testing method thereof, wireless control over a variable-frequency power source can be achieved by the aid of a touch screen, operating personnel can control a testing main machine within a certain distance, and the safety of site operating personnel can be guaranteed as much as possible.

Description

technical field [0001] The invention relates to the field of electrical installation engineering construction of a power system, in particular to a wireless frequency conversion resonance voltage withstand test device and a test method thereof. Background technique [0002] In the handover test of electrical equipment in the installation of electrical installations, there are usually two methods for the insulation withstand voltage test of electrical equipment: DC withstand voltage test and AC withstand voltage test. Frequency conversion resonant AC withstand voltage test is one of the main methods to assess the insulation strength of electrical equipment, especially for high-voltage, large-capacity tested products. When using the traditional frequency conversion resonance withstand voltage test device for testing, the operator needs to perform correct wiring according to the test circuit and perform manual operation, record the test data, and judge whether the tested produc...
