Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a transformer with lightning protection function. Background Technology

[0002] In power transmission and distribution systems, transformers, as core equipment for voltage conversion and power distribution, directly determine the reliability of the power grid's supply. Since transformers are mostly installed outdoors (such as on top of utility poles or in the outdoor areas of substations), they are highly susceptible to lightning strikes. Overvoltages generated by lightning can puncture the transformer's insulation layer, leading to coil burnout, core damage, and other faults, causing widespread power outages and incurring repair costs of tens of thousands of yuan. Therefore, surge arresters are used.

[0003] However, traditional surge arresters used for transformers still have certain drawbacks. For example, after a lightning strike, the surge arrester is prone to failure due to overvoltage breakdown and needs to be replaced immediately to restore the transformer's protection function. However, the fixing structure of traditional surge arresters mostly relies on bolts for fastening. Special tools such as wrenches and screwdrivers are required for disassembly and assembly. When performing emergency repairs outdoors, it is inconvenient to carry these tools, which makes the replacement process cumbersome, seriously delays the progress of emergency repairs, and lacks practicality.

The upper surface of the mounting base 2 is provided with a pressing groove 20, the inner surface of the pressing groove 20 is slidably connected to the pressure plate 8, which facilitates the overall fixation of the surge arrester 5. The outer surface of the inclined block 15 is provided with a limiting groove 21, the inner surface of the limiting groove 21 is slidably connected to the limiting block 13, which is used to limit the movement of the limiting block 13. The outer surface of the mounting base 2 is... The surface is provided with a wire groove 22, the inner surface of which is adapted to the grounding wire 6 for easy placement of the grounding wire 6.

When the L-shaped buckles 17 correspond to the slot 19, release the pressure plate 8. Under the action of the rebound force of the stainless steel spring 14, the L-shaped buckles 17 will automatically snap into the slot 19, thus completing the installation of the new surge arrester 5. It is simple, convenient and does not require tools.
