Description

Technical Field

[0001] The invention relates to the technical field of voltage transformer field testers, and in particular to a voltage transformer field tester with simple wiring operation. Background Art

[0002] Voltage transformers are similar to transformers in that they are instruments used to transform voltage. However, the purpose of transformers in transforming voltage is to facilitate the transmission of electrical energy, so their capacity is very large and is generally calculated in kilovolt-amperes or megavolt-amperes. The purpose of voltage transformers in transforming voltage is mainly to power measuring instruments and relay protection devices, to measure the voltage, power and electrical energy of the line, or to protect valuable equipment, motors and transformers in the line when a line fault occurs. Therefore, the capacity of voltage transformers is very small, generally only a few volt-amperes or tens of volt-amperes, and the maximum does not exceed one kilovolt-ampere. During the use of voltage transformers, they need to be tested on-site using a tester.

[0003] However, during the use of the existing voltage transformer field tester, the connecting wire is inserted into the wiring terminal of the device. During the insertion process, there is a phenomenon of poor contact due to insufficient insertion force of the connecting wire, and this phenomenon is not understood by the staff, which not only affects the operating performance of the device, but also affects the test results of the device, reducing the practicality of the device. Secondly, during the use of the existing voltage transformer field tester, most of the tests are carried out outdoors, and there is a situation where the staff cannot clearly view the test data on the display screen due to the strong outdoor light intensity. The staff needs to watch and confirm repeatedly, which wastes time and reduces the functionality of the device. In addition, during the use of the existing voltage transformer field tester, since there is no placement position for the connecting wire, the connecting wire needs to be taken out, and the connecting wire is easily lost during the taking-out process, resulting in the device being unusable, affecting the performance of the device. Therefore, a voltage transformer field tester with simple wiring operation is urgently needed to solve the existing problems. Summary of the invention

[0004] The purpose of the present invention is to provide a voltage transformer field tester with simple wiring operation in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A voltage transformer field tester with simple wiring operation comprises a shell, a shell cover, a lock handle and a lock seat, wherein the shell cover is installed on the upper end of the shell, the lock seat is arranged on one side wall of the shell cover, the lock handle is installed on one side wall of the shell, a lifting handle is arranged on one side of the lock handle, a sponge pad is installed on the inner wall of the shell cover, a detector is installed in the shell, a power interface is arranged on one side of the upper end of the detector, a switch is arranged on one side of the power interface, a touch display screen is arranged on one side of the switch, a wiring terminal is installed above the touch display screen, an annular pressure sensor is installed in the wiring terminal, a controller is arranged on one side of the bottom end of the wiring terminal, an indicator light is arranged on one side of the controller, a USB interface is arranged on one side of the wiring terminal, a grounding terminal is arranged on one side below the switch, a concave cavity is arranged on the upper end of the detector, a voice announcer is installed in the concave cavity, a storage drawer is arranged on the other side wall of the shell, a pull ring is arranged on one side wall of the storage drawer, a wire trough is installed in the storage drawer, a heat dissipation cavity is arranged on the back wall of the shell, and a dustproof net is installed in the heat dissipation cavity.

[0012] By adopting the above technical solution, one end of the power cord is connected to the external power supply, and the other end is plugged into the power interface, thereby providing the required electrical energy to the detector, and at the same time, the switch control device is turned on and off.

[0013] Furthermore, the touch display screen is electrically connected to the detector.

[0015] Furthermore, the wiring terminal is electrically connected to the detector, the annular pressure sensor is connected to the wiring terminal via a slot, the controller is electrically connected to the annular pressure sensor, and the indicator light is electrically connected to the controller.

[0016] By adopting the above technical solution, one end of the connecting wire is connected to the voltage transformer, and the other end is connected to the wiring terminal.

Then, one end of the power cord is connected to the external power supply, and the other end is plugged into the power interface to provide the required power to the detector. At the same time, the detector is turned on by the switch, and then one end of the connecting wire is connected to the voltage transformer, and the other end is connected to the wiring terminal. During the connection process, the annular pressure sensor can detect the pressure of the connecting wire on the wiring terminal. When the detection value reaches the set value, the controller controls the indicator light to operate, thereby reminding the staff that the wiring is connected, which not only ensures the operating performance of the device, but also ensures the test results of the device. The grounding wire is then connected to the grounding terminal, and then the corresponding parameters are adjusted through the touch display screen and the detector is controlled to detect it. When the detection is completed, the staff can view the test data through the touch display screen, and the voice announcer in the concave cavity can play the data to be detected, so that when the external light intensity is strong, there is no need to repeatedly watch the data on the touch display screen to understand the detection data of the device. The heat generated during the detection process of the device passes through the heat dissipation cavity.
