[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] This embodiment mainly solves the following three problems: (1) Different test instruments are selected based on different on-site tests, and they are repeatedly transported to the site to carry out on-site power tests; (2) Considering that some power test sites have difficulty in obtaining electricity, it is necessary to appropriately lengthen the power cord to quickly solve the power supply problem at the power test site; (3) The power test site involves some withstand voltage tests, which must take into account the heavy weight of the equipment, which increases the labor intensity of the test staff. Design and manufacture a detachable trolley suitable for the power test site. At the same time, it greatly reduces the production operation intensity of the staff at the power test site.

[0033] Based on the above three questions, please refer to Figure 1-3 This embodiment provides a technical solution: a switch cabinet on-site mobile test trolley, which effectively solves the actual production work needs of the current power test site that requires continuous transportation of test instruments, and effectively solves the on-site power supply problem. It includes a folding trolley 1, including:

[0034] The withstand voltage test bench 2 is used to place switch cabinet test equipment and various wiring and accessories. The withstand voltage test bench 2 has a built-in energy storage power supply and inverter module 7 for on-site power supply. The withstand voltage test bench 2 has an external socket area 4, and the socket area 4 is electrically connected to the energy storage power supply and inverter module 7. The withstand voltage test bench 2 includes an outer shell bracket 3, the top of the outer shell bracket 3 is a quadrangular platform structure, and the socket area 4 is arranged on a side surface of the quadrangular platform. The energy storage power supply and inverter module 7 are designed as an integral module, wherein the outer shell bracket 3 is a fixed support for the entire module, and the socket area 4 is located on the handle side of the folding cart 1 for easy wiring. The internal wiring is connected to the energy storage power supply and inverter module 7 through a wiring harness, and a national standard socket design is adopted for on-site power supply. The energy storage power supply and inverter module 7 are located at the bottom of the outer shell bracket 3, with a power of 3kW, and are used for on-site power supply.

[0035] The other three sides of the table are all arranged as instrument placement area 5. The angle between the four sides of the four-sided table structure and the ground is 45°, which is used to place switch cabinet testing equipment, such as switch meter, return resistance meter and other equipment. A drawer-type accessory placement area 6 is set in the middle of the shell bracket 3 for placing various wiring and accessories.

[0036] Test transformer 9, used for conducting withstand voltage test on the equipment under test;

[0037] Two sets of self-locking mechanisms 8 are used to detachably mount the withstand voltage test bench 2 and the test transformer 9 on the folding trolley 1. The self-locking mechanism 8 includes a screw 81, a clamping rod 82, a slider 1 83, a connecting rod 84 and a slider 2 85. The screw 81 is rotatably mounted on the bottom of the folding trolley 1. The slider 2 85 is screwed on the screw 81 through a thread. The clamping rod 82 is arranged on both sides of the withstand voltage test bench 2 and the test transformer 9. The clamping rod 82 matches the clamped device, such as Figure 2 As shown, the bar rod cooperates with the withstand voltage test bench 2, and the V-shaped rod cooperates with the test transformer 9. Three groups of sliders 1 83 are fixedly connected at the bottom of the clamp rod 82. The sliders 1 83 are slidably matched with the slide slots 101 on the folding trolley 1, and the sliders 1 83 and the sliders 2 85 are rotatably connected through the connecting rod 84. The withstand voltage test bench 2 or the test transformer 9 is placed on the folding trolley 1, and the screw rod 81 is rotated clockwise. According to the principle of thread transmission, the slider 2 85 is driven to move along its axial direction. Under the linkage action of the connecting rod 84, the slider 1 83 drives the two groups of clamp rods 82 connected thereto to move relative to each other, clamping the withstand voltage test bench 2 or the test transformer 9 on the folding trolley 1. The structure is simple and the operation is convenient. The screw rod 81 is reversed to release the restriction of the clamp rod 82 on the withstand voltage test bench 2 or the test transformer 9, so as to facilitate the removal of the withstand voltage test bench 2 or the test transformer 9.

[0038] This embodiment can achieve the following functions and effects:

[0039] (1) It meets the test requirements of different test instruments on the folding cart 1. It can not only carry out relevant power tests directly on the folding cart 1, but also conveniently remove the test instruments from the folding cart 1 for testing;

[0040] (2) The folding car 1 has a power supply function to provide power for various tests, and the power meets the requirements of relevant tests;

[0041] (3) When conducting direct tests on the folding vehicle 1, the safety distance meets the safety requirements, especially when conducting a withstand voltage test;

[0042] (4) The folding cart 1 has storage space for various accessories and cables to meet the storage needs of instruments;

[0043] (5) The folding cart 1 is light in weight, meets insulation requirements, and is easy to transport and carry.

[0044] Working principle: When using, when it is necessary to conduct an on-site test, first transport the folding trolley 1, the withstand voltage test bench 2, the housing bracket 3, the socket area 4, the instrument placement area 5, the accessory placement area 6, the energy storage power supply and inverter module 7 and the test transformer 9 to the test site separately, and then open the folding trolley 1 on site, and place the withstand voltage test bench 2, the housing bracket 3, the socket area 4, the instrument placement area 5, the accessory placement area 6, the energy storage power supply and inverter module 7 and the test transformer 9 on the self-locking mechanism 8 on the folding trolley 1;

[0045] Next, push the trolley to the vicinity of the device under test, and carry out relevant wiring and tests. If a withstand voltage test is required, move the test transformer 9 off the trolley for the withstand voltage test. If a withstand voltage test is not required, other tests can be carried out directly. When the device under test completes the required test, simply remove the test wiring from the device under test (the trolley end does not need to be removed), and then push the entire test trolley to the next device under test for the next round of tests;

[0046] If all the tested devices have completed the relevant tests, the whole module and the test transformer 9 can be removed from the trolley and transported back to the warehouse.
