The central control panel 200 is integrated with the central control component towards one side of the accommodating space, and because the 10kV breaker is subjected to 5-item tests after completing a complete handover test, the integrated central control component is used for controlling the 5-item test, and parameters required by the 5-item test are different (such as different current and voltage), and the integrated central control component is also used for controlling relevant output parameters of the integrated equipment so as to match with parameters required by the content of the current test item, so that the 10kV breaker handover test is controlled by one central control platform.

Because the high-voltage test module 300 has larger electromagnetic interference to the co-packaged low-voltage test module 400, the low-voltage test module 400 can be damaged by the interference generated by the output voltage 40kV of the high-voltage test, so that the high-voltage test module 300 is arranged in the electromagnetic shielding shell 500 in an insulating manner, the electromagnetic shielding shell 500 is reliably grounded, the electromagnetic shielding shell 500 can shield the electromagnetic interference, so that the electromagnetic interference generated by the high-voltage test module 300 is shielded by the electromagnetic shielding shell 500, and the influence on the low-voltage test module 400 is avoided. The high-voltage test module 300 comprises a semi-insulating test PT310 and a high-voltage electric connection plug 320 electrically connected with the semi-insulating test PT310, wherein the semi-insulating test PT310 is a critical device in the high-voltage test module 300, in the prior art, a full-insulating boost PT is generally adopted, the volume and the weight of the full-insulating boost PT are large, and the full-insulating boost PT is difficult to directly integrate into the box 110, and when the high-voltage test is carried out in the prior art, the full-insulating boost PT is independently carried due to the large volume and the large weight, and if the full-insulating boost PT is directly integrated into the box 110, the weight and the volume in the box 110 are large, so that the small-sized design and the carrying are not facilitated.

Through the above modes, the high-voltage test module 300 and the low-voltage test module 400 are integrated into the closable box 100, and the integrated equipment disclosed by the utility model can complete the test of 5 items of the 10kV breaker, so that 5 sets of test instruments are avoided to be used for testing in a rotating way, and thus, the need of frequent switching of the test instruments by workers is avoided, and the wiring is only needed once in the 10kV breaker switching test process, so that the need of frequent disassembly of test lines by workers due to the fact that each set of test instruments are used for testing are used for each individual wiring test is avoided, the need of switching test instruments and frequent disassembly of test lines in the whole test process is avoided, the operation is convenient and simple, the workload of the workers is reduced, and the work efficiency is improved. Meanwhile, the miniaturization design of the integrated equipment is facilitated through the modes, so that the integrated equipment is more convenient to carry and transport, the occupied area of the integrated equipment in the miniaturization design is small, the integrated equipment is not limited by the limited space of the actual test site, and because the integrated equipment integrates the high-voltage test module 300 and the low-voltage test module 400, a switching test instrument is not needed, the problem that in the prior art, the switching test instrument is inconvenient to operate due to the fact that the switching test instrument is needed, and the occupied area is large and limited by the site space is solved.
