Problems solved by technology

In actual use, it is found that the contacts, solid-sealed poles, busbars and other components are overheated. The existing switchgear only expands the hot air inside and discharges it from the air outlet on the top. The temperature rise will affect the performance and life of the insulation parts of the equipment, and it will directly affect the safe and stable operation of the equipment. Once the temperature of the switchgear is too high to cause a failure, it will often cause the busbar of the substation to stop, and the scope of influence is very large.

Embodiment Construction

[0025] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] The specific embodiment of switchgear of the present invention, as Figure 1 to Figure 4 As shown, the switch cabinet includes a cabinet body 1, and the top of the cabinet body 1 is provided with heat dissipation holes, which is beneficial to the hot air inside the cabinet body to flow upward. The inner cavity is divided into left and right parts, and the busbar 7 is arranged on the upper part of the right inner cavity. The riser 8 is used for installing electrical components such as contact boxes, and ventilation holes are provided on the riser 8 to facilitate air flow in the chambers on both sides. A partition 2 is provided near the lower part of the left chamber, and the partition 2 divides the left chamber into a circuit breaker chamber 3 at the upper part and a cable chamber 6 at the lower part.

[0027] The partition board 2 includes a hor...

Abstract

The invention relates to a switchgear and a cabinet thereof. The cabinet of the switchgear is internally provided with an air inlet channel communicated with a breaker cavity directly, an inlet of the air inlet channel is arranged in the sidewall of the cabinet, and an outlet of the air inlet channel is arranged in a separator plate. During use, external air enters the breaker cavity directly via the air inlet channel and is prevented from scattering in a cable chamber, so that air in the air inlet channel flows to the breaker cavity directly, and air circulation in the breaker cavity is enhanced; and arrangement of the inlet of the air inlet channel in the lateral side also helps entrance of air. The heat radiation effect is enhanced obviously due to high airflow performance.

Description

technical field [0001] The invention relates to a switch cabinet and its cabinet body. Background technique [0002] The switchgear is an important equipment for distributing electric energy in the substation. The switchgear includes a cabinet body. The cabinet body is divided into an upper circuit breaker room and a lower cable room by a partition set inside it. The circuit breaker is installed in the circuit breaker room. The cabinet The top of the body is provided with an air outlet connecting the circuit breaker room and the external environment. In actual use, it is found that the contacts, solid-sealed poles, busbars and other components are overheated. The existing switchgear only expands the hot air inside and discharges it from the air outlet on the top. The temperature rise will affect the performance and life of the insulation parts of the equipment, and directly affect the safe and stable operation of the equipment. Once the temperature of the switchgear is too ...
