Description

Technical Field

[0001] The present application relates to the technical field of testers, and in particular to a parameter tester chassis for a transformer. Background Art

[0002] With the continuous development of the power industry, transformer parameter testers play a vital role in the operation and maintenance of power systems. To meet the needs of on-site testing, portable parameter testers have emerged. They are installed in a suitcase and can be easily carried to various workplaces. In order to protect the tester from external shock and vibration, the contact between the parameter tester and the suitcase is designed to be quite close. This close contact ensures the stability of the tester during transportation and storage, and the closed design is used to achieve waterproof and dustproof effects.

[0003] However, this design also brings a significant problem in actual use: the suitcase adopts a fully enclosed structure, and the tester fits tightly with the suitcase, so the heat generated by the tester during operation cannot be effectively dissipated. Long-term heat accumulation may not only cause the internal temperature of the tester to rise, thereby affecting its working performance and accuracy, but also shorten the service life of the tester.

[0004] Secondly, the suitcase was originally designed for easy carrying, but in actual use, in order to prevent the parameter tester from overheating, taking it out of the suitcase for use has become a big problem. Especially in outdoor or complex working environments, frequently opening the suitcase, taking out the tester, measuring, and then putting the tester back into the suitcase not only increases the burden on the operator, but may also cause damage to the tester or data loss due to improper operation.

[0005] In view of the above problems, a transformer parameter tester chassis is now designed. Utility Model Content

[0006] The embodiment of the present application provides a transformer parameter tester chassis to solve the problem in the related art that the suitcase adopts a fully enclosed structure, the tester and the suitcase fit tightly together, and the heat generated by the tester during operation cannot be effectively dissipated.

[0010] In some embodiments, the lifting mechanism includes an electric push rod and several telescopic rods. The electric push rod is arranged inside the box, and several telescopic rods are arranged inside the box. The electric push rod piston rod is connected to the bottom of the mounting plate, and the top of the inner tube of the telescopic rod is connected to the mounting plate.

[0011] In some embodiments, a threading tube is disposed on the box body, and the threading tube is used for threading electric wires or cables. A sealing cover is threadedly connected to the threading tube.

[0012] In some embodiments, the placement model includes a plastic plate, the plastic plate is disposed on a mounting plate, and a covering layer is disposed on the outside of the plastic plate.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] An embodiment of the present application provides a transformer parameter tester chassis, which can solve the problem in the related art that the suitcase adopts a fully enclosed structure, the tester and the suitcase fit tightly together, and the heat generated by the tester during operation cannot be effectively dissipated.

[0026] See also Figure 1-Figure 3 A transformer parameter tester chassis includes: a box body 1, a box cover 2, a lifting mechanism 3 and a mounting plate 4, the box cover 2 is hingedly arranged on the box body 1, the lifting mechanism 3 is arranged inside the box body 1, the lifting mechanism 3 is connected to the mounting plate 4 and is used to drive the mounting plate 4 to rise and fall; a placement model 5 is arranged on the mounting plate 4, the placement model 5 is used to accommodate the parameter tester, and the mounting plate 4 and the placement model 5 are both provided with heat dissipation holes 6 that are interconnected at the bottom.

[0027] In actual use, the box cover 2 is hingedly arranged on the box body 1, allowing the box cover to be easily opened and closed, making it convenient for operators to put in or take out the parameter tester.

[0028] When the parameter tester needs to be taken out or put in, the lifting mechanism will drive the mounting plate 4 to move up and down. This design avoids the tedious steps of the operator to manually take out the tester, improves the convenience of operation, and allows the heat generated by the tester during operation to be discharged through the holes through the mounting plate 4 and the heat dissipation holes 6 at the bottom of the placement model 5, thereby preventing heat from accumulating inside the chassis. At the same time, the design of the heat dissipation holes also ensures the sealing of the chassis, preventing dust and debris from entering the chassis and affecting the operation of the tester.

[0029] The mounting plate 4 is provided with a placement model 5, which is designed according to the shape and size of the parameter tester and is used to stably accommodate the tester. The placement model is firmly connected to the mounting plate to ensure the stability of the tester during the lifting process.

[0030] It can be understood that the placement model 5 and the box body 1 have an accommodating chamber for installing a parameter tester opened inside the placement model 5, and the accommodating chamber is adapted to the parameter tester.

[0031] Specifically, Figure 2 and Figure 3 As shown, the lifting mechanism 3 in this embodiment includes an electric push rod 31 and a plurality of telescopic rods 32. The electric push rod 31 is arranged inside the box body 1, and the plurality of telescopic rods 32 are arranged inside the box body 1. The piston rod of the electric push rod 31 is connected to the bottom of the mounting plate 4, and the top of the inner tube of the telescopic rod 32 is connected to the mounting plate 4.

[0032] When the electric push rod 31 is started, the piston rod will move telescopically, thereby driving the mounting plate 4 to rise or fall. The control of the electric push rod can be achieved through electrical signals, and the operator can start or stop the work of the electric push rod through a button, switch or remote control device, thereby conveniently controlling the lifting and lowering of the mounting plate 4.

[0033] The main function of the telescopic rod 32 is to provide additional support and stability to ensure the stability and safety of the mounting plate 4 during the lifting process. When the electric push rod 31 drives the mounting plate 4 to lift, the telescopic rod 32 will also extend and retract accordingly, working in conjunction with the electric push rod to support the weight of the mounting plate 4.

[0034] Preferably, in this embodiment, a threading tube 7 is disposed on the box body 1 , and the threading tube 7 is used for threading electric wires or cables. A sealing cover is threadedly connected to the threading tube 7 .

[0035] The threading tube 7 is relatively arranged on the box body 1, providing a passage for the wires or cables to be threaded. Since the parameter tester needs to be connected to a power source and may transmit data with other devices, the arrangement and management of the wires or cables are particularly important. Through the threading tube 7, the operator can neatly thread the wires or cables into the threading tube 7, avoiding the disorder of the wires or cables, and also facilitating subsequent maintenance and repair work.

[0036] In actual operation, when it is necessary to thread wires or cables, the operator can open the sealing cover, pass the wires or cables through the threading tube and then enter the inside of the chassis. After the threading is completed, the operator tightens the sealing cover to ensure the sealing of the chassis. This design is not only convenient for operation, but also can effectively keep the inside of the chassis clean and dry.

[0037] Specifically, Figure 3 As shown, the placement model 5 in the present scheme includes a plastic plate 51, and the plastic plate 51 is arranged on the mounting plate 4. A coating layer 52 is arranged on the outside of the plastic plate 51, wherein the top end of the inner side of the coating layer 52 is arc-shaped, and the coating layer 52 is a pearl cotton coating layer.

[0038] The plastic plate 51 is used as a basic structure for placing the model, and is arranged on the mounting plate 4 to provide a stable supporting surface for the parameter tester. The plastic plate 51 is an engineering plastic plate.

[0039] The coating layer 52 is arranged outside the plastic plate 51 to increase the cushioning performance and protection ability of the placed model. The inner top of the coating layer 52 is designed in an arc shape, which can better adapt to the shape of the parameter tester, ensuring that the tester can fit tightly when placed and is not easy to shake. In addition, the material of the coating layer 52 is pearl cotton, which is a material with good cushioning and heat insulation properties. The pearl cotton coating layer can effectively reduce the impact and vibration of the tester during transportation and storage, and protect the tester from damage.

[0040] Preferably, Figure 4 As shown, in this embodiment, a group of exhaust fans 8 are relatively arranged at the bottom of the placement model 5, and the bottom ends of the exhaust fans 8 pass through the bottom heat dissipation holes 6. The apertures of the heat dissipation holes 6 on the placement model 5 are smaller than the apertures of the heat dissipation holes 6 on the mounting plate 4, so that a group of relatively arranged exhaust fans 8 can extend downward inside the heat dissipation holes 6 of the mounting plate 4.

[0041] The exhaust fan 8 is installed at the bottom of the placement model 5, and its bottom end passes through the heat dissipation hole 6 at the bottom, so that the exhaust fan 8 can blow air directly toward the bottom of the tester, effectively dissipating the heat generated by the tester through the heat dissipation hole 6.

[0042] It is worth noting that the diameter of the heat dissipation holes 6 on the placement model 5 is designed to be smaller than the diameter of the heat dissipation holes 6 on the mounting plate 4, so that a group of relatively arranged exhaust fans 8 can extend downward inside the heat dissipation holes 6 of the mounting plate 4. This extension not only increases the distance between the exhaust fans 8 and the bottom of the tester, making the wind flow more concentrated and powerful, but also provides a larger operating space for the exhaust fans 8, reducing the problem of poor heat dissipation due to space limitations.

[0043] In actual use, when the tester starts working, the exhaust fan 8 will start, sucking in external cold air and blowing it to the bottom of the tester through the heat dissipation holes 6. At the same time, since the heat generated by the tester during operation will rise, the heat will also be discharged to the outside of the chassis through the heat dissipation holes 6 by the exhaust fan 8.

[0044] Further, if Figure 3 As shown, in this embodiment, a buffer layer 9 is provided inside the box body 1, and the placement model 5 is in contact with the inner side of the buffer layer 9, wherein the buffer layer 9 is an EPE interlayer.

[0045] As a preferred embodiment, Figure 3 As shown, the present embodiment also includes a power supply module 10, which is arranged inside the box 1, and the power supply module 10 is electrically connected to the electric push rod 31, and the power supply module 10 is electrically connected to the parameter tester. The power supply module 10 includes a battery, and the electric push rod 31 and the parameter tester can be temporarily powered by the battery.

[0046] When the external power supply is unavailable, the battery can be used as a backup power supply to provide temporary power supply for the electric actuator 31 and the parameter tester. This design allows the entire chassis to maintain functional integrity when the power is off or when it is used on the move, greatly improving the flexibility and convenience of use.

[0047] In actual operation, when the electric push rod 31 needs to be started to lift the mounting plate 4, the power supply module 10 will provide it with the required power. At the same time, when the parameter tester starts working, the power supply module 10 will also supply power to it to ensure its normal operation. If the external power supply is suddenly interrupted, the battery will start immediately to provide uninterrupted power supply for the electric push rod 31 and the parameter tester, avoiding operation interruption or data loss caused by power failure.

[0048] It should be further explained that the power supply module 10 in this embodiment also includes a power monitoring module and a charging management module. When the power is insufficient, it can issue a reminder so that the operator can charge the battery in time. At the same time, it will also intelligently manage the charging process to ensure the safe and efficient use of the battery. This is a prior art and will not be repeated here.

[0049] It should be noted that if Figure 1As shown, in this embodiment, a lock is provided between the box body 1 and the box cover 2, and the box cover 2 is fixed by the lock.

[0050] Furthermore, a plurality of anti-collision modules 11 are arranged on the box body 1, wherein the anti-collision modules include anti-collision strips and protrusions.

[0051] The anti-collision module 11 can significantly reduce the damage to the device caused by collision or vibration during transportation and storage, prevent the device from being damaged by collision or scratch, and thus extend the service life of the device.
