Detailed Implementation

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] This invention aims to improve the efficiency and convenience of withstand voltage testing, solving problems related to the transportation, storage, management, and use of withstand voltage testing equipment. Based on the specific characteristics of each component of the withstand voltage testing equipment, a modular mobile workstation is integrated and manufactured. This workstation serves as a carrier for the withstand voltage tester and its testing fixtures and accessories, and also functions as a withstand voltage testing workbench. It integrates functionality, flexibility, aesthetics, safety, durability, and stability. Depending on the testing requirements, the workstation can operate in both separate and combined modes, such as... Figure 1 , Figure 2 , Figure 3 The workstation consists of a steel frame 1, a mother-daughter load-bearing platform 2, an insulation protection system 3, and withstand voltage testing equipment.

[0029] The combined withstand voltage test workstation of the present invention includes a steel structure frame 1, a mother-daughter type support platform 2 and an insulation protection system 3. The mother-daughter type support platform 2 is equipped with an insulation protection system 3 on its exterior, and the insulation protection system 3 is equipped with a steel structure frame 1 on its exterior. The mother-daughter type support platform 2 is equipped with a track base plate 4, a loading and unloading tail plate 5 and a brake tray 6. The brake tray 6 is equipped with the track base plate 4 and the loading and unloading tail plate 5. The loading and unloading tail plate 5 includes a base plate 7, and two side plates 8 are provided in the middle of the base plate 7. A clamping plate 9, a pull ring 10 and a connecting plate 11 are provided between the two side plates 8. Two pins 13 are provided between the clamping plate 9 and the connecting plate 11, and springs 12 are sleeved on the outside of the pins 13.

[0030] The steel frame 1 of this invention is connected to the workstation grounding point 17. The insulation protection system 3 includes a triangular bracket 14, a right-angle bracket 15, and an SMC insulation plate 16. The insulation protection system 3 includes several SMC insulation plates 16, and the insulation protection system 3 is equipped with a triangular bracket 14 and a right-angle bracket 15. The steel frame 1 is equipped with four casters, of which the two front casters are swivel casters, and the two rear operating side casters are swivel brake casters. The brake tray 6 is equipped with four swivel brake casters. The steel frame 1 is welded from 40mm*40mm*2mm square tubes and 30mm*30mm*2mm square tubes. The partition is made of 2mm aluminum-zinc coated plate welded to the frame. Two studs are welded to the bottom front of the frame as grounding connection points. The steel frame 1 is divided into three spaces: upper, middle, and lower. The lower space is divided into a transformer compartment and a power cord compartment, the upper space is an operating table, and the middle space is a semi-enclosed storage space for storing test equipment. The workstation measures 640mm*640mm*1330mm. It contains four SMC insulation boards (16), each 5mm thick.

[0031] Example:

[0032] The workstation in this embodiment measures 640mm*640mm*1330mm (length*width*height) and includes four casters: two swivel casters at the front and two swivel brake casters on the rear operating side. The operating surface height is 1050mm, ergonomically designed for comfortable standing work. The workstation has a rectangular shape and occupies less than one square meter of floor space. It includes a transformer compartment, an operating table compartment, a power cord reel compartment, a testing fixture compartment, and a writing / recording desktop for the operator. The steel frame 1 is welded from 40mm*40mm*2mm square tubing and 30mm*30mm*2mm square tubing. The partitions are made of 2mm thick aluminum-zinc coated steel sheet welded to the frame. Figure 4 , Figure 5As shown, two studs are welded to the bottom front of the frame as grounding connection points. The frame structure is divided into upper, middle, and lower spaces. The lower space is divided into a transformer compartment and a power cord reel compartment. Considering that these two components do not require operation and the transformer is the heaviest, they are placed at the bottom of the workstation to lower the overall center of gravity, significantly enhancing the stability of the workstation during movement. The upper space of the workstation is the operating table, 250mm deep and 1050mm from the ground, facilitating writing and recording. The operating table is placed at a 45° angle and embedded in the frame, with a viewing angle that is easy to observe. The operating table can be controlled with a slight extension of the arm, making operation effortless. The middle position of the frame is designed with an independent semi-enclosed storage space for storing test fixtures. Considering the storage environment and retrieval efficiency, the test fixtures are designed to be placed horizontally and can only be put in and taken out from one side, ensuring both the cleanliness of the test fixtures and the convenience of retrieval.

[0033] The mother-daughter type support platform 2 is located on the bottom of the workstation and is fixed to the workstation frame by welding and bolting. It is a sunken design, lower than the workstation floor but slightly higher than the ground (approximately 25mm), ensuring passability during workstation movement and preventing contact with the ground. The function of the mother-daughter type support platform 2 is to carry and transport transformers, facilitating loading and unloading, and enabling both separate and combined operation modes to adapt to different testing environments. The mother-daughter type support platform 2 consists of a track base plate 4, a loading / unloading tail plate 5, and a brake tray 6. The track base plate 4 is formed by bending a 4mm steel plate into an "arch" shape, with reinforcing ribs welded to the back to ensure load strength. The base plate 7 of the loading / unloading tail plate 5 is also formed by bending a 4mm steel plate with triangular edges. When the loading / unloading tail plate 5 is laid down on the ground, it serves as a support foot, forming an angle of approximately 5° with the ground. This creates a small ramp between the track base plate 4 and the ground, facilitating the brake tray 6 to push the transformer up and down. Figure 6 As shown. A spring-loaded locking mechanism is installed on the loading / unloading tail plate 5. Its function is to lock the tail plate 5 when it is retracted, firmly fixing it to the workstation. Simultaneously, it prevents the transformer from slipping off the track base plate 4 when the workstation moves. The spring-loaded locking mechanism consists of left and right side plates 8, clamping plates 9, pull rings 10, connecting plates 11, pins 13, and springs 12. Figure 7 When unlocking is required, pull up the pull ring 10, and the pin 13 disengages from the lock hole. At this time, the loading and unloading tail plate 5 can be laid down. When retracting is required, pull up the pull ring 10 to stand up the loading and unloading tail plate 5, release the pull ring 10, and the pin 13 inserts into the lock hole, fixing the tail plate back to its original position. The brake tray 6 is specially designed according to the shape of the transformer and is used in conjunction with the track base plate 4 and the loading and unloading tail plate 5. It is a carrier used for transporting transformers and is equipped with 4 brake casters, allowing for easy loading and unloading, flexible turning, and stopping at any position.

[0034] The insulation protection system 3 completely encloses the transformer compartment. It consists of four 5mm thick SMC insulation boards 16, several right-angle brackets 15, and triangular brackets 14, all spliced ​​and fixed to the workstation frame. All bolts inside the insulation protection system 3 are made of nylon, and the seams are filled with sealant. Figure 9 As shown. The top of the transformer should be at least 100mm away from the insulation protection system 3. This provides effective protection and ensures personal safety during low-level withstand voltage tests (such as secondary circuit insulation withstand voltage tests). For withstand voltage tests of 12kV and above, the transformer needs to be used separately from the main workstation.

[0035] When using the test equipment, 1) Before use, prepare the following: Position the test equipment's operating console on the side of the workstation platform; fix the transformer on the brake tray of the mother-daughter support platform; place the test fixture in the storage compartment on the side; and connect the cable between the operating console and the transformer. 2) Move the workstation to the area of ​​the product to be tested, step on the workstation casters to bring the workstation to a stop, ensuring it is fixed and will not slip during use. 3) Pull up the pull ring of the loading / unloading tailplate; the pin will disengage from the locking hole in the base plate. Lay the loading / unloading tailplate flat and push the transformer along the track to the ground to complete the unloading process. Figure 8 As shown; 4) Separate the transformer from the main body of the workstation (if performing a low-level withstand voltage test, it is not necessary to separate the transformer); 5) Maintain a sufficient electrical safety distance between the transformer and the workstation, and brake the casters; Take out the test fixture from the middle partition on the workstation side, install the test fixture on the gas-filled cabinet, connect the cable between the transformer and the bushing, and connect the grounding wire (including the grounding protection of the workstation); 6) Turn on the main power of the withstand voltage tester operating table and start the withstand voltage test according to the standard procedure; 7) After the withstand voltage test is completed, restore the above steps, install the transformer on the workstation, lock the loading and unloading tail plate to prevent the transformer from shaking and falling, and store the test fixture and other accessories to facilitate the implementation of 5S and visual management.

[0036] This invention integrates transportation, storage, and operation, facilitating transport, avoiding repeated handling and arrangement, preventing labor injuries caused by manual handling, providing convenient operation, high safety protection, and easy management. The invention features an integrated structure, combining multiple equipment components together. The workstation is equipped with casters for easy transport and storage, facilitating 5S management. Its innovative design, with a welded and integrally molded appearance, is simple and aesthetically pleasing. Its compact size (640mm*640mm) saves space and allows for flexible use. Depending on the scenario, it can be used in combination or separately, offering diverse functions. Its ergonomic design ensures convenient and comfortable operation. The transformer compartment is located at the bottom, working with a mother-daughter support platform, making loading and unloading the transformer easier, eliminating the need for strenuous lifting and preventing labor injuries. It is equipped with insulation protection for safety and reliability.
