Description

Technical Field

[0001] The present invention relates to the technical field of transformer cabinets, and in particular to a high-efficiency heat dissipation and intelligent protection transformer cabinet for electric power transmission and transformation. Background Art

[0002] In the power system, the substation cabinet is a key device responsible for converting high-voltage electric energy into low-voltage electric energy suitable for users and distributing it to various power branches. With the continuous growth of power demand and the complexity of the power grid structure, the substation cabinet faces higher operating pressure and more complex operating environment. Especially under harsh conditions such as high temperature, dust, and humidity, the heat dissipation performance and protection ability of the substation cabinet become key factors affecting its stable operation.

[0003] Most existing substations use a metal enclosed structure. Although it can effectively protect the internal electrical components from the external environment, the heat dissipation performance is limited.

[0020] 1. This scheme sets up temperature sensors, air compressor components, vortex tubes and temperature control modules for cooling the substation cabinet. When the temperature information detected by the temperature sensor exceeds the set temperature threshold, the air compressor component is controlled to start and the air intake solenoid valve is opened. The high-pressure gas output by the air compressor component is passed into several vortex tubes, so that the cold air outlet of the vortex tube sprays cold air, and the cooling fan arranged above the cold air outlet of the vortex tube transports the cold air from bottom to top, so as to absorb and discharge the heat generated by the substation cabinet. The hot air outlet of the vortex tube is connected to the lower end of the two-stage telescopic rod through a three-way joint; and the three-way joint is also connected to the water vapor outlet of the atomizer. The high-temperature and high-pressure hot air and water vapor are mixed to obtain water vapor, and the water vapor will be passed into the two-stage telescopic rod and the connecting rod, driving the inner straight tube of the first two-stage telescopic rod to gradually extend, so that the water vapor sprays the outer surface of the solar panel, covering the middle and upper area of ​​the solar panel. At the same time, the U-shaped tube of the second two-stage telescopic rod is driven, so that the water vapor sprays the outer surface of the solar panel, covering the middle and lower area of ​​the solar panel. Thereby, the solar panels can be cleaned while the transformer cabinet is cooled.

[0021] 2. The counterweight, travel switch, upper cleaning submodule and lower cleaning submodule are set up. The counterweight can slow down the moving speed of the first connecting rod and the second connecting rod, so that the cleaning effect of water vapor is better, and the first connecting rod and the second connecting rod can be easily reset under the action of gravity. The upper cleaning submodule detects the position of the first connecting rod according to the electromagnetic signals of the first Hall sensor and the second Hall sensor, so as to open and close the first pressure relief solenoid valve, and the effect is also to slow down the moving speed of the first connecting rod and the second connecting rod, so that the cleaning effect of water vapor is better. The same is true for the lower cleaning submodule. BRIEF DESCRIPTION OF THE DRAWINGS
