DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The purpose of the present invention is to provide a digital transformer calibration device to solve the problems existing in the prior art, facilitate disassembly and maintenance, and achieve accurate heat dissipation during instrument operation.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-Figure 7 As shown, the present embodiment provides a digital transformer calibration device, including a protection frame, a sliding mounting frame 11, a digital transformer calibrator 10, a plurality of heat dissipation modules and a plurality of temperature detection modules. The digital transformer calibrator 10 can be detachably mounted on the upper end of the sliding mounting frame 11, which is convenient for removing the digital transformer. The sliding mounting frame 11 is slidably connected to the protection frame, and the sliding mounting frame 11 can drive the digital transformer calibrator 10 to be pulled out or pushed into the protection frame. When the digital transformer calibrator 10 needs to be overhauled, the digital transformer calibrator 10 can be directly pulled out through the sliding mounting frame 11, which is easy to operate, improves the overhaul efficiency, and is heat dissipated. The thermal module and the temperature detection module are both movably installed on the upper end of the sliding mounting frame 11 and located on the periphery of the digital transformer calibrator 10. The temperature detection module can detect the temperature of different positions of the digital transformer calibrator 10 during movement, thereby realizing real-time detection of the temperature of various locations of the digital transformer calibrator 10. The heat dissipation module cools down the digital transformer calibrator 10 according to the temperature signal detected by the temperature detection module. When the temperature detection module detects that the temperature is high at a certain location, it stops moving. At this time, the heat dissipation module increases the power and dissipates heat, thereby realizing precise heat dissipation processing, improving the heat dissipation effect, and thereby improving the detection accuracy of the digital transformer calibrator 10.

[0021] Specifically, the protective frame includes a base frame 1 and a shielding protective cover 3. The digital transformer calibrator 10 can be detachably connected to the upper end of the base frame 1 through a fixed connecting plate 14. The two sides of the sliding mounting frame 11 are slidably connected to the base frame 1, so that the digital transformer calibrator 10 can be pushed in and pulled out by the sliding mounting frame 11. The shielding protective cover 3 is provided at the upper end of the base frame 1 and is located on the outer periphery of the digital transformer calibrator 10, so that the digital transformer calibrator 10 can be shielded and protected from dust. At the same time, it also has the ability to resist interference with external electromagnetic fields, so that the digital transformer calibration device in this embodiment can be stably operated and used in harsh outdoor environments.

[0022] The shielding protective cover 3 is opened on both sides, and the openings on both sides of the shielding protective cover 3 are respectively connected with a side baffle plate 6 through a locking threaded column 5. Preferably, a slide groove is provided on both sides of the shielding protective cover 3, and the side baffle plate 6 can be slidably connected in the slide groove, and the front end of the locking threaded column 5 is squeezed and contacted with the side baffle plate 6 to achieve the fixation of the side baffle plate 6. The side baffle plate 6 is parallel to the moving direction of the sliding mounting frame 11. The side baffle plate 6 plays an auxiliary role. Whether to install the side baffle plate 6 can be selected according to actual needs. When the outdoor environment is harsh, the locking threaded column 5 can be screwed to The extrusion pressure on the side baffle plate 6 can be removed, so that the side baffle plate 6 can be slid and pulled out from both sides of the shielding protective cover 3, so as to facilitate the plug-in use of the digital transformer tester 10, so as to protect the digital transformer tester 10 and prevent the digital transformer tester 10 from being damaged by rain or the like; an observation window is provided on the upper end surface of the shielding protective cover 3, and an observation panel 4 is connected to the observation window. The detection result is observed through the observation panel 4, so that the digital transformer tester 10 can be fully and safely protected outdoors without affecting normal use.

[0023] A receiving groove for accommodating the sliding mounting frame 11 is provided in the middle of the bottom frame 1, one side of the receiving groove is open and is used for pushing and pulling the sliding mounting frame 11, and a first limiting card groove 13 is provided on each of the two opposite inner side walls of the receiving groove, and the length direction of the first limiting card groove 13 is consistent with the moving direction of the sliding mounting frame 11, and a sliding card plate 18 is installed at each end of the sliding mounting frame 11, and the two first limiting card grooves 13 and the two sliding card plates 18 correspond one to one, and the sliding card plates 18 can be slidably connected to the corresponding first limiting card grooves 13, and then through the mutual limitation of the first limiting card groove 13 and the sliding card plates 18, the movement of the sliding mounting frame 11 is guided, ensuring that the sliding mounting frame 11 can be smoothly pushed in and pulled out, and to a certain extent, avoiding jamming during the pulling and pulling process.

[0024] The cross-sections of the first limiting groove 13 and the sliding clamping plate 18 are both T-shaped, which can achieve a stable limiting connection.

[0025] A fixed baffle plate 9 is installed at the opening of the bottom frame 1 by means of bolts, and a plurality of fans 7 are installed on the fixed baffle plate 9, and the fans 7 can play an auxiliary ventilation and moisture-proof role.

[0026] Two second limit slots 12 are symmetrically provided on the upper end surface of the sliding mounting frame 11, and the two second limit slots 12 are respectively located on both sides of the digital transformer calibrator 10. Each second limit slot 12 is slidably connected to a sliding adjustment seat 16. A heat dissipation module and a temperature detection module are installed on the side of each sliding adjustment seat 16 away from the digital transformer calibrator 10. Then, the reciprocating movement of the heat dissipation module and the temperature detection module is realized by the reciprocating sliding of the sliding adjustment seat 16 in the second limit slot 12, so as to realize accurate temperature measurement and heat dissipation of different positions of the digital transformer calibrator 10 during the movement.

[0027] The lower end of the sliding adjustment seat 16 passes through the second limit slot 12 and extends into the bottom frame 1. A group of electric push rods 19 are installed on both sides of the bottom frame 1. The movement direction of the electric push rods 19 is parallel to the movement direction of the sliding mounting frame 11, and the movement end of the electric push rods 19 is connected to the lower end of the sliding adjustment seat 16. The electric push rods 19 can drive the sliding adjustment seat 16 and the heat dissipation module and temperature detection module provided on the sliding adjustment seat 16 to move, thereby realizing accurate temperature measurement and heat dissipation at different positions of the digital transformer tester 10. At the same time, the electric push rods 19 are automatically controlled by the controller, and then the start and stop of the electric push rods 19 are automatically controlled according to the specific temperature information detected by the temperature detection module, so as to ensure that the heat dissipation module can perform accurate heat dissipation according to the actual temperature conditions.

[0028] A humidity sensor is installed on the inner side of the sliding adjustment seat 16. The humidity sensor is set between the corresponding heat dissipation module and the temperature detection module. The humidity sensor is used to detect the humidity in the bottom frame 1 and can serve as an alarm when the humidity is high to avoid affecting the normal use of various structures due to excessive humidity.

[0029] An auxiliary moving wheel 2 is installed at the lower end of one side of the protective frame, which is convenient to move and carry during use. A push-pull handle 8 is connected to the side of the protective frame opposite to the auxiliary moving wheel 2. The push-pull handle 8 can be retracted and extended. By adjusting the length of the push-pull handle 8, the digital transformer calibration device in this embodiment can be pulled and carried by users of different heights.

[0030] The heat dissipation module is a heat dissipation fan 15 , and the temperature detection module is an infrared thermometer 17 , which cooperates with the sliding of the sliding adjustment seat 16 to realize dynamic scanning temperature measurement.

[0031] As another preferred solution, the heat dissipation module can also be a heat dissipation structure such as a heat dissipation fin or a heat pipe, and can be fully fitted with the outer wall of the digital transformer tester 10, thereby increasing the heat exchange area and efficiency with the external environment; the shielding protective cover 3 can also be set to be made of a material with good thermal conductivity, such as aluminum alloy, so as to quickly transfer the internal heat to the surface of the shell and dissipate it. In this embodiment, multiple temperature sensors and heat dissipation control modules can be set inside the shielding protective cover 3 to monitor the internal temperature in real time and adjust the heat dissipation position as needed, so as to minimize the battery power consumption when used outdoors, thereby improving the endurance of the digital transformer tester 10 and achieving timely heat dissipation.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
