A kind of siphon principle automatically closes the transformer cabinet that prevents rainwater from entering

Abstract

The invention discloses a variable motor cabinet capable of automatically preventing rainwater from entering by siphon principle, its structure includes siphon waterproof inflow device, Door locks, cabinet doors, under the action of the height difference between the water guide pipe and the water outlet, enhanced siphon effect, better drain the water collected from the rainwater-proof device, andthe diameter of the inner wall of the catchment tank is 0.1 cm, so that only a small amount of rainwater is needed to make the water level in the catchment tank higher than the commanding elevation point of the pipeline, thereby triggering the siphon effect, Under the action of the water collecting tank and the air guide plate, the rainwater can be collected better to prevent the rainwater from accumulating. Under the action of the starting device and the ventilation closing device, the gap between the ventilation closing device and the air guide plate can be closed to prevent the water from entering the cabinet of the variable motor.

Description

technical field [0001] The invention relates to the field of electric equipment, more precisely, it relates to a power transformer cabinet which can be automatically closed to prevent rainwater from entering according to the siphon principle. Background technique [0002] Transformer cabinets are the most commonly used basic power equipment, used to load instruments, meters, electronics, communications, cables and other items. However, in typhoon or rainy weather, micro-liquids are easily produced inside the transformer cabinets, and over time the miniature If the liquid reaches a certain amount, it will cause the transformer cabinet to malfunction, or even cause an electrical accident. The current technical considerations are not comprehensive, and it has the following disadvantages: [0003] When the transformer cabinet is in typhoon or rainy weather, the rainwater will flow into the transformer cabinet through the cooling holes along with the wind, making it easy to produ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a power transformer cabinet that automatically closes to prevent rainwater from entering according to the siphon principle, so as to solve the problem that the rainwater will flow with the wind in the typhoon or rainy weather of the prior art transformer cabinet. It flows into the inside of the transformer cabinet through the heat dissipation holes, making it easy to generate micro-liquid inside the transformer cabinet. Over time, the micro-liquid reaches a certain amount, which will cause the transformer cabinet to malfunction and even cause electrical accidents
