Background

With the rapid development of national economy and urbanization, industrial and agricultural production and residential electricity consumption in China are rapidly increasing, the demand of complete sets of switch equipment serving as important components of power systems is increasing day by day, and the switch equipment is widely applied to factories, enterprises, schools and residential areas.

In the operation and use process of the switch equipment, due to abnormal operation environment, misoperation of field operators and other reasons, the insulation performance of the equipment can be reduced, so that the equipment has interphase insulation breakdown and is ignited to generate electric arcs, which is generally called as internal arc faults.

In switchgear, internal arcing faults occur very rarely, but cannot be completely avoided, which can simultaneously generate phenomena such as heat, sound, light, electromagnetic waves, shock waves and the like, and cause mechanical and thermal effects on the equipment through the rapid expansion of high-temperature gas, and in addition, hot gas and incandescent particles are sprayed to the outer shell;

although current switchgear devices typically have dedicated top pressure relief ducts for releasing such gases and particles, it is inevitable that some hot gases and hot particles may escape from the gap between the door panel and the cabinet, thereby causing harm to personnel and other equipment around the device; and the hinge formula cabinet door that switchgear all adopted basically at present, this just makes and must have the clearance between door plant and the cabinet body for above-mentioned problem is difficult to avoid.

in the attached drawing, 1 is a door panel, 2 is a cabinet side plate, 3 is a U-shaped partition plate, 4 is a Z-shaped partition plate, 5 is a second sealing strip, 6 is a compartment upper beam, 7 is the inside of a compartment, 8 is a compartment lower beam, 9 is a hinge, 10 is a door panel opening position, 11 is a first sealing strip, and 12 is a bending section.

Detailed Description

Referring to fig. 1-2, the complete set of switch equipment door hinge side sealing structure comprises a door plate 1, a cabinet side plate 2 and a sealing assembly; the door plate is hinged with the side plate of the cabinet body through a hinge 9, and a sealing assembly is arranged between the hinge and the side plate of the cabinet body; the sealing assembly comprises a U-shaped clapboard 3 and a Z-shaped clapboard 4; the U-shaped partition plate is surrounded by an upper side plate, a lower side plate and a connecting plate which connects the upper side plate and the lower side plate into a U shape; the exposed end of the upper side plate extends towards the side plate of the cabinet body and is connected with the bottom surface of the side plate of the cabinet body, and a first sealing strip is arranged on the bottom surface of the lower side plate. Through the cooperation of the U-shaped partition plate and the Z-shaped partition plate, hot gas and incandescent particles in the interior of the partition chamber can be effectively blocked when the door plate is closed; and because the bottom surface of the lower side plate is provided with the first sealing strip 11, the sealing effect is greatly enhanced, and the effect of blocking hot gas and incandescent particles in the interior of the compartment is further enhanced.

The Z-shaped partition plate is formed in a Z shape by enclosing an upper folding edge, a lower folding edge and a vertical plate connected with the upper folding edge and the lower folding edge; the upper folded edge is fixedly connected (welded) with the back of the U-shaped partition plate, and the bottom surface of the lower folded edge is provided with a second sealing strip 5. Two sealing strips are respectively adhered to the equal-height folded edges of the U-shaped partition plate and the Z-shaped partition plate, and when the door plate is closed, the inner side of the door plate is in contact with and pressed by the two sealing strips, so that a double-sealing effect is formed.

The lower folded edge and the lower side edge of the U-shaped partition plate form an equal-height surface. Because hem and downside limit form the equal altitude face down, indirectly make two sealing strips on the coplanar, when the door plant was closed, sealed effect was better.

The first sealing strip and the second sealing strip are both high-temperature resistant sealing strips. Because the hot gas and the red-hot particle temperature in the door plate inner partition chamber are higher, the high-temperature-resistant sealing strip is adopted, the sealing effect is good, and the service life is long.

The top end of the hem of the door panel close to one side of the hinge is bent inwards to form a bent section 12, and the bent section and the hem of the door panel are in arc transition. Through setting up the circular arc transition, make things convenient for opening and closing of door plant.

The following working principle is described:

the U-shaped partition board 3 is arranged between the hinge 9 and the cabinet body side board 2 between the compartment upper beam 6 and the compartment lower beam 8, one folded edge of the Z-shaped partition board 4 is welded on the back surface of the U-shaped partition board 3, and the other folded edge and the folded edge of the U-shaped partition board 3 form an equal-height surface. Two high-temperature-resistant sealing strips 5 are respectively adhered to the equal-height folded edges of the U-shaped partition plate 3 and the Z-shaped partition plate 4, when the door plate 1 rotates from the door plate opening position 10 and is closed, the inner side of the door plate is in contact with the two high-temperature-resistant sealing strips 5 and is pressed tightly, a double-sealing effect is formed, and hot gas and red-hot particles in the compartment interior 7 cannot overflow through a gap between the cabinet body and the door plate.

The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
