Transformer cabinet

Abstract

The invention provides a transformer cabinet. The transformer cabinet comprises a cabinet body and a power inlet assembly. The power inlet assembly comprises a fixing base, a relay and a three-phase electric copper plate. Avoiding holes are formed in the three-phase electric copper plate; an assembly component is arranged on the side wall of the three-phase electric copper plate; the assembling assembly comprises an insulating limiting pipe and a limiting buckle arranged at the tail end of the insulating limiting pipe. The limiting buckle is inserted into the inner wall of the cabinet body; and the top end of the cabinet body is provided with a waterproof seat. The middle of the waterproof seat is recessed downwards to form a water collecting groove, a water drainage notch is formed in thegroove wall of the water collecting groove, a drainage plate is arranged on the side, opposite to the water collecting groove, of the water drainage notch, a water tank is arranged below the drainageplate, a water pump is arranged in the water tank, the output end of the water pump is connected with the input end of a water cooling pipe, and the water cooling pipe is arranged on the cabinet. Through the design of the fixing base, the relay and the three-phase electric copper plate, the transformer in the cabinet body is powered in a transverse mode, drilling on the cabinet body is not needed, and rainwater is prevented from permeating into the cabinet body.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer cabinet. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are widely used in residential quarters, commercial centers, industrial and mining enterprises, hospitals, schools and other places. In order to protect the transformer, the transformer is usually placed in the transformer cabinet. There are two types of transformer cabinets, indoor and outdoor, which are used to install the transformer and some auxiliary equipment. The transformer cabinet plays a certain role in protecting the equipment, such as implemen...

AI Technical Summary

Problems solved by technology

[0003] There are many kinds of existing transformer cabinets, but in the process of using the existing transformer cabinets, the vertical power supply method is used to supply power to the voltage devices in the transformer cabinets during the power-in operation process, and then it needs to be installed on the top of the transformer cabinets. Drilling is carried out to achieve the effect of avoiding the wire harness of the power supply line. However, due to the drilling on the top of the transformer cabinet, rainwater infiltration is prone to occur in rainy weather, thereby reducing the safety performance of the transformer.
