[0055] In the embodiment, the electrical connection of each functional module 16 is completed by using the prior art.
[0056] In the embodiment, the main body 1 is shaped like a common luggage box, and is in the shape of a rectangular parallelepiped, and the length, width and height are about 65 cm, 42 cm and 30 cm respectively, which is similar to a common 24-inch luggage box, and is extremely convenient to move in various spaces.

[0059] In the present embodiment, the functional modules 16 can be divided into control modules, sampling systems, memories, voltage regulating modules and program-controlled load modules according to their functionalities. The functional modules 16 with different functionalities are installed separately and do not interfere with each other. Among them,
[0060] The control module adopts Atmel AT32F403A as the core operation unit. The chip has powerful data processing capability and high-speed operation performance, and can respond accurately to various instructions in an instant.

After the operator selects the corresponding circuit breaker model on the operation panel 2, the intelligent control algorithm can automatically match and execute the corresponding test process according to the characteristics of different types of circuit breakers, realizing automatic testing. For example, for circuit breakers with different rated currents and voltages, the algorithm can automatically adjust the output current of the simulated load module, the output voltage of the voltage regulating module and other parameters, ensuring the accuracy and effectiveness of the test.
[0061] The sampling system is composed of a voltage transformer, a current transformer, a voltage sampling circuit and a current sampling circuit.

The device is built-in cooling filling liquid for heat dissipation, which can effectively reduce the temperature of the simulation load module in the working process, and ensure its stable operation. The simulation load module adopts modular and expandable design, and users can flexibly add or replace different types and specifications of load modules according to actual test requirements. For example, when testing circuit breakers in some special industries (such as new energy power, rail transit, etc.), the corresponding special load module can be quickly configured to meet the specific test requirements.

When the power module 12 and the function module 16 are purchased from the prior art, since the power module 12 and the function module 16 in the prior art can not have space to accommodate the power limiting slot and the guide slot, at this time, the power limiting slot can be accommodated in the form of setting a first side panel with the power limiting slot on the side of the power module 12, and the guide slot can be accommodated in the form of setting a second side panel with the guide slot on the side of the function module 16.
