Example Embodiment

[0020] Example 1

[0021] See figure 1 In the embodiment of the present invention, a moisture-proof base for an electrical cabinet includes a base body 1; the upper four corners of the base body 1 are provided with retaining slots 2 to facilitate nested installation of the electrical cabinet on the base body 1; the base body 1 is provided with a wiper board 4, the wiper board 4 is fixedly connected with a sleeve 5, the sleeve 5 penetrates a protective cover 6, the protective cover 6 is a rectangular box structure, the sleeve 5 is rotatably connected with the protective cover 6 through a bearing sleeve The sleeve 5 is sleeved and fixed with the output shaft 7 of the drive motor 8, and the drive motor 8 is electrically connected to the external power supply. When the electrical cabinet returns to moisture, the collected water droplets fall to the bottom of the cabinet homeopathically, and the drive motor 8 passes through the output shaft 7 drives the sleeve 5 and the wiper board 4 ...

Example Embodiment

[0022] Example 2

[0023] See Figure 1-4 The difference between this embodiment and embodiment 1 is that: the protective cover 6 is provided with fan blades 9 which are sleeved on the drive shaft 7 and rotate with the drive shaft 7; the upper end of the protective cover 6 is provided with The vent holes 10 are nested with dust-proof nets, and the vent holes 10 are arranged in a circumferential distribution; there is a resistance wire 11 below the vent hole 10, and the resistance wire 11 is electrically connected to an external power source, and the fan blades 9 The resistance wire 11 is blown to generate hot air, which is discharged from the air outlet 10 and blown to the cabinet floor, and is accelerated to the circumferential direction under the action of the wiper 4 to accelerate the drying of the cabinet floor.

[0024] The upper end surface of the base body 1 is provided with baffles 3 distributed in a circumferential direction. The baffles 3 are located between the locking ...

Example Embodiment

[0025] Example 3

[0026] The difference between this embodiment and embodiment 2 is: please refer to figure 1 A humidity sensor 14 is fixedly connected to the inner wall of the base body 1, the humidity sensor 14 is electrically connected to a single-chip computer 15, the single-chip computer 15 is fixedly connected to the outer surface of the base body 1, and the single-chip computer 15 is electrically connected to the resistance wire 11 and the driving motor 8, respectively, When the humidity sensor 14 detects that the humidity in the base body 1 is relatively high, it transmits the signal to the single-chip computer 15, and the single-chip computer 15 starts the drive motor 8 and the resistance wire 11 to dry the cabinet.

Abstract

The invention discloses a dampproof base of an electrical cabinet. The dampproof base comprises a base body, a water scraping plate is arranged in the base body, a sleeve is fixedly connected with thewater scraping plate, the sleeve penetrates through a protection cover and fixedly sleeves an output shaft of a driving motor. By arranging the water scraping plate and an annular water groove, waterdrops at the bottom of a cabinet body are scrapped and collected, and the drying of the cabinet body is accelerated; by arranging fan blades and a resistance wire, generated hot air is used for drying the cabinet body; and meanwhile, by arranging the water scrapping plate and a diversion plate, the hot air is diffused, the hot air is vertically and upwards blown through an arc air introduction passage of the diversion plate, the drying of a surrounding side wall of the cabinet is accelerated, normal working of the electrical cabinet is ensured, and humidity is prevented from entering the cabinet.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a moisture-proof base for an electrical cabinet. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. Load shedding; the main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers...
