Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides Figures 1-5 The vehicle-mounted integrated resonant reactor shown includes:

[0022] A resonant reactor 1, wherein an excitation transformer 2 is provided at the bottom of the resonant reactor 1, and fixed brackets 3 are connected to both sides of the bottom of the resonant reactor 1;

[0023] A vehicle carrier 4 is provided with a rear door 5 hinged at the rear of the vehicle carrier 4 and a resonant inductor 1 is arranged inside the vehicle carrier 4. A capacitive voltage divider 6 is provided on the top of the resonant inductor 1. The excitation transformer 2 and the capacitive voltage divider 6 are integrated and installed on the surface of the resonant inductor 1 to form a whole, so that the resonant inductor 1 can be transported and tested with the vehicle carrier 4.

[0024] A reactor oil conservator 7 and a bushing outlet line 8 are respectively provided on the top of the resonant reactor 1 and on both sides of the capacitive voltage divider 6 .

[0025] The surface of the resonant inductor 1 is connected to a number of mounting ears 9. The mounting ears 9 and the fixing brackets 3 can provide convenient fixing points for the resonant inductor 1 when it is installed in the vehicle carrier 4, so that the resonant inductor is firmly installed in a suitable position of the vehicle carrier 4, ensuring that the resonant inductor 1 will not shift or shake during the driving of the vehicle carrier 4.

[0026] The resonant inductor 1 is provided with two sets of connection terminals 10 on its surface, through which the external power supply can be electrically connected to the excitation transformer 2, so that the electric energy provided by the external power supply can be input into the excitation transformer 2 to provide it with the energy required for operation.

[0027] A cable AC withstand voltage test vehicle comprises the above-mentioned vehicle-mounted integrated resonant reactor.

[0028] It also includes a cable reel 11 and a variable frequency power supply 12. The cable reel 11 is arranged in the vehicle carrier 4, and the variable frequency power supply 12 is installed in the vehicle carrier 4 through a bracket. By adjusting the frequency of the variable frequency power supply 12, the resonant circuit composed of the resonant inductor 1 and the tested cable and other equipment can be made to resonate at a specific frequency, thereby generating the required high voltage.

During the test, the rear door 5 is opened to connect the resonant reactor 1. After the test wiring is completed, the withstand voltage test can begin. After the withstand voltage test is completed, the line is reeled in, the rear door 5 is closed, and the vehicle can leave the test site. Therefore, the test tasks and requirements can be completed within a very short power outage maintenance time, greatly reducing the test and maintenance time.
