Detailed Description

The invention will be described in further detail below with reference to the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation is given, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1 and fig. 2, an LCI valve set device according to the present embodiment includes an insulating housing 1, a disc spring device 2, a heat sink set 3, a capacitor 4, a metal cabinet assembly 5, and a trigger plate 6; the insulating shell 1 is a device shell formed by processing and combining insulating materials, and comprises a top plate, a bottom plate, a back plate and two side plates, so that the insulating shell effectively plays an insulating and protecting role and can achieve a weight reducing role in material properties;

the radiating fin group 3 is vertically arranged inside the insulating shell 1 and used for enabling the whole LCI valve group device to radiate heat and being matched with an air cooling system to evacuate heat of the machine body quickly; the opening direction of the insulating shell 1 below the radiating fin group 3 is horizontally provided with a trigger plate 6, the radiating fin group 3 and the trigger plate 6 are vertically and alternately arranged, a capacitor 4 vertically arranged along a side plate is arranged between the radiating fin group 3 and the side plate of the insulating shell 1, the top of the radiating fin group 3 is provided with a disc spring device 2, the disc spring device 2 upwards extends to penetrate through the top plate of the insulating shell 1 to adjust and fix the radiating fin group 3, and meanwhile, the installation is convenient.

The metal cabinet body assembly 5 wraps the insulating shell 1, the metal cabinet body assembly 5 is made of Q235 steel plates, the structure is firm and durable, the surface is painted, and the corrosion resistance is good.

Because the LCI valve bank device is integrally installed and debugged, the integral volume and weight are far smaller than those of the previous similar products, and the processing and production cost is correspondingly reduced; the main body of the device is installed and debugged by adopting a disc spring device, which is more convenient and faster than the press mounting and debugging of the previous similar products, the whole device adopts an air cooling device to dissipate heat quickly, the ventilation effect is good, and the whole device can realize the power which can meet two kiloamperes to the maximum after the assembly is finished; the whole shell of the shell is made of Q235 steel plates, the structure is firm and durable, the surface is painted, the corrosion resistance is good, and the shell can be more suitable for the field installation environment.

The above description is only a preferred embodiment of the present invention, and these embodiments are based on different implementations of the present invention, and the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
