Description

Technical Field

[0001] The utility model belongs to the improvement of the lower guard plate structure of the operating mechanism of ultra-high voltage circuit breakers, and particularly relates to an improved lower guard plate of the operating mechanism of ultra-high voltage circuit breakers. Background Art

[0002] For the products currently operating in the power grid, problems existing in the circuit breaker operating mechanism are described as follows: 1. The circuit breaker guard plate uses SMC material, which is heavy in weight, increasing the difficulty during disassembly and installation and being prone to being knocked and broken. 2. The viewing window of the product is relatively small, making it impossible to observe the internal mechanism. There is a hydraulic mechanism inside the product, and sometimes oil leakage occurs, which cannot be judged through the viewing window. 3. There is no viewing window at the bottom of the product. When the hydraulic oil leaks and drips to the bottom, the amount of oil leakage can only be seen by removing the guard plate. Content of the Utility Model

[0003] The purpose of the utility model is to provide an improved lower guard plate of the operating mechanism of ultra-high voltage circuit breakers, with a reasonable structure, capable of clearly observing the leakage point and the leakage amount when hydraulic oil leaks, and improving the quality of the circuit breaker guard plate.

[0004] The purpose of the utility model is realized as follows: An improved lower guard plate of the operating mechanism of ultra-high voltage circuit breakers includes a lower guard plate installed at the lower part of the operating mechanism of ultra-high voltage circuit breakers. Two transverse reinforcing ribs are evenly arranged on the outer wall of the semi-cylindrical lower guard plate. An oil extraction port is arranged on the bottom surface on the left side of the lower guard plate. A measuring bottle made of transparent material is installed on the oil extraction port through threaded connection. Measuring scales are evenly arranged on the measuring bottle. A longitudinal oil channel is arranged on the inner wall at the bottom of the lower guard plate, and the longitudinal oil channel is communicated with the oil extraction port.

[0005] In the utility model, the reinforcing rib in the middle of the circuit breaker operating mechanism guard plate is retained, transverse reinforcing ribs are filled at the bottom of the guard plate, and a sloping oil channel is reserved at the same time. An oil extraction port is provided on the left side of the guard plate, and a 500-gram measuring cup is installed at the bottom of the guard plate along the oil extraction port. When hydraulic oil leaks, the leakage point and the leakage amount can be clearly observed.

[0006] The structure of the utility model is reasonable. When hydraulic oil leaks, the leakage point and the leakage amount can be clearly observed, improving the quality of the circuit breaker guard plate. Description of the Drawings
