Description

Technical Field

[0001] This utility model relates to the technical field of power equipment commissioning and calibration instruments, and more specifically, to a multi-functional calibration instrument for power equipment installation and commissioning. Background Technology

[0002] The installation and commissioning of power equipment is a crucial step in ensuring the stable operation of the power system. Among these, calibration instruments, as key testing tools, play a vital role in assessing the safety and reliability of power equipment. There are many types of calibration instruments on the market, most of which can be used to verify the error of electricity meters on-site, check the correctness of the wiring of metering devices, test the transformation ratio and polarity of current transformers used for metering, and measure the power quality of users (including voltage harmonics, current harmonics, voltage balance, total harmonic distortion, etc.).

[0003] Because calibrators are relatively heavy, traditional calibrators typically have handles. While these handles allow for gripping and carrying, prolonged use can increase the burden on workers, causing arm pain and making them less effortless to carry. Furthermore, these calibrators lack components for movement along the ground, affecting portability. Additionally, most calibrators rely primarily on their outer casing for heat dissipation, which has limited effectiveness. Therefore, we propose a multi-functional calibrator for the installation and commissioning of power equipment. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 This utility model provides a technical solution: a multi-functional calibrator for power equipment installation and commissioning, including a calibrator body 1, a protective shell 2 on the outside of the calibrator body 1, a handle 22 fixedly installed on the front side of the protective shell 2, the handle 22 having a U-shaped cross-section and being used for gripping and operation; a top cover 3 is hinged to the top surface of the rear side plate of the protective shell 2, two symmetrical buckles 23 are fixedly installed on the front side of the protective shell 2, and two symmetrical hooks 31 are fixedly installed on the front side of the top cover 3, the buckles 23 and the hooks 31 engage with each other to fix the protective shell 2 and the top cover 3, and the buckles 23 and the hooks 31 are both existing conventional technologies, which will not be described in detail here;

[0028] Specifically, multiple rollers 21 are fixedly installed on the rear side of the protective housing 2, and a pull rod 24 is fixedly installed on the bottom surface of the protective housing 2. This allows the device to be moved and carried easily when the rollers 21 are pressed against the ground, making it convenient to carry the device to the corresponding verification location for verification operations during the installation and commissioning of power equipment.

[0029] Specifically, a heat dissipation component 4 is provided inside the protective housing 2. The heat dissipation component 4 includes a rectangular tube 40 fixedly installed on the rear side wall of the protective housing 2. Multiple air outlets 43 are provided on the front side of the rectangular tube 40. A fan 42 is provided at the end of the rectangular tube 40 to realize the cooling by blowing air through the fan 42, which helps to ensure the stability of the verification operation during the installation and commissioning of power equipment.

[0030] In this embodiment, multiple support legs 20 arranged in a matrix are fixedly installed on the bottom surface of the protective shell 2. The height of the support legs 20 is greater than the thickness of the pull rod 24, so that the support legs 20 can be used to support the horizontal placement operation on the ground.

[0031] Specifically, a storage chamber 25 is provided between one side plate of the protective shell 2 and the main body 1 of the calibrator. The top of the storage chamber 25 is connected to the outside. The storage chamber 25 can be used to place cables, etc.

[0032] Furthermore, a text labeling area 30 is provided on the upper surface of the top cover 3, which can be used to display the model number, etc.

[0033] In addition, a cotton pad 32 is fixedly installed on the inner surface of the top cover 3. Multiple storage pockets 33 are provided on the front side of the cotton pad 32. A zipper 34 is provided at the opening of the storage pocket 33. The storage pocket 33 is used for storing other items.

[0034] It is worth noting that an air inlet pipe 41 is fixedly installed at one end of the rectangular tube 40, and a fan 42 is fixedly installed on the wall of the air inlet pipe 41; an electrostatic eliminator 44 is fixedly installed at the other end of the rectangular tube 40. The electrostatic eliminator 44 is inserted into the rectangular tube 40, so that electrostatic elimination can be performed using the electrostatic eliminator 44, which helps to ensure the stability of the verification operation during the installation and commissioning of power equipment and makes it less susceptible to the influence of static electricity.

[0035] It is worth noting that the air outlet 43 faces the side of the calibrator body 1 and is set at a downward tilt of 30° to 60°. Since the shell of the calibrator body 1 is made of metal, which has thermal conductivity, the air blowing towards the shell of the calibrator body 1 can promote the discharge of heat and improve the heat dissipation effect.

[0036] Finally, it should be noted that the main body 1 of the calibrator, the fan 42 and the static eliminator 44 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0037] When using the multi-functional tester for power equipment installation and commissioning of this utility model, the buckle 23 is locked onto the hook 31. At this time, the handle 22 can be held for carrying, or the roller 21 can be used to support the ground, and the lever 24 can be held for moving and carrying.

[0038] After the main body 1 of the calibrator is moved to the inspection area, the buckle 23 is unfastened. At this time, the top cover 3 is opened, and the calibration operation is performed using the main body 1 of the calibrator. The fan 42 is connected to an external power source and made to work. The fan 42 can blow air. In conjunction with the static eliminator 44 being connected to an external power source and made to work, the static eliminator 44 can ionize and generate positive and negative ions. The air blows the positive and negative ions toward the main body 1 of the calibrator, which can eliminate static electricity and dissipate heat.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
