Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a voltage transformer with a lightning protection structure. Background Art

[0002] Voltage transformers are similar to transformers and are instruments used to transform voltage. However, the purpose of transformers to transform voltage is to facilitate the transmission of electrical energy, so the capacity is very large, and is generally calculated in kilovolt-amperes or megavolt-amperes; while the purpose of voltage transformers to transform 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 thousand volt-amperes.

[0003] After searching, it was found that the announcement number was CN211578571U, and the name was voltage transformer. The application proposed that the installation between the traditional voltage transformer and the base was mostly fixed by multiple bolts. In actual use, multiple voltage transformers would mostly be installed on the top of the base. Each voltage transformer was fixed to the base by multiple bolts, which reduced the convenience of installation. Moreover, when the equipment was running, there would be certain vibrations. The bolts were not locked after being fixed, and they might become loose under long-term vibration, posing certain safety hazards. By aligning the fixing hole inside the fixing disk with the fixing column on the top of the base, the fixing column was slid into the inner side of the fixing hole. At this time, the rotating column was rotated and bent to form a 90° angle between the rotating column and the fixing column. At this time, the side wall of the rotating column was fitted with the top of the fixing disk, and the threaded sleeve was rotated to drive the thread The rotary sleeve moves downward so that the bottom of the threaded rotary sleeve fits with the top of the rotating column, thereby completing the installation of the voltage transformer body. Compared with the traditional method of fixing by screwing together multiple bolts, in this device, only the threaded rotary sleeve needs to be rotated to complete the installation, thereby improving the convenience of installation. However, when the voltage transformer in this application is installed outdoors at high altitude, it lacks a separate lightning protection structure and is easily affected by lightning strikes, causing failures in use. At the same time, traditional lightning rods or lightning protection belts are extended by welding connections, and installation and disassembly are relatively troublesome, and further improvements can be made. At the same time, when fixing, the application has more overall manual operation steps, and the convenience of installation can also be further improved. At the same time, the voltage transformer in this application has poor insulation isolation from the surrounding environment and is easily affected by the movement of surrounding charges, which can also be further improved.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
