Substation knife switch mechanism box water seepage prevention device

Abstract

The invention discloses a water seepage prevention device for a disconnecting link mechanism box of a transformer substation. The device comprises a disconnecting link mechanism box and a connecting rod, wherein the disconnecting link mechanism box comprises a connecting rod, the disconnecting link mechanism box is operated through rotation of the connecting rod, the disconnecting link mechanism box further comprises a water seepage prevention device, and the water seepage prevention device comprises a rain shielding eave which is arranged in the circumferential direction of an outer wall faceof the connecting rod and located above the disconnecting link mechanism box so as to prevent the rainwater from flowing into the disconnecting link mechanism box along the connecting rod. The deviceis advantaged in that the rainwater in all directions can be prevented from entering the knife switch mechanism box, so internal element damage caused by water seepage can be effectively prevented, operation and maintenance cost is reduced, device faults are effectively reduced, and device operation reliability is improved.

Description

technical field [0001] The invention relates to an anti-seepage device for a switch mechanism box of a substation, and belongs to the technical field of waterproofing of a switch mechanism box. Background technique [0002] In substations, due to water entering the knife gate mechanism box, damage to internal components often occurs. The main reason is that the connecting rod of the knife gate mechanism box has fallen due to long-term rainwater, and the seal between the connecting rod and the knife gate mechanism box is poor, causing water to enter the mechanism box. Moisture will cause damage to internal components (such as auxiliary switch damage, DC grounding, motor and circuit breaker burnout, etc.), resulting in the phenomenon that the knife switch cannot operate correctly and the position signal is abnormal. At present, the most common treatment method is to use glass glue to seal the place where the connecting rod enters the mechanism box, but due to the corrosion of ...
