Cooling channel for breaker chamber of KYN switch cabinet

Abstract

The invention discloses a cooling channel for a breaker chamber of a KYN switch cabinet. The cooling channel comprises a cabinet body, wherein two layers of honeycomb cabinet plates are arranged in the cabinet body, and the same support plate is fixedly arranged between and connected with the two layers of honeycomb cabinet plates. By arranging a filtering device, air blown into the switch cabinet can be filtered, dust accumulation in the cabinet is avoided, and a filtering structure can be cleaned in the cooling process of the breaker chamber; on the premise that electrical elements and distances of the breaker chamber are not changed and the functions of a pressure relief channel and all functional chambers are reserved, the problem that the KYN cabinet is not provided with a ventilation channel is solved; through the arrangement of a switch cabinet sealing mechanism, the switch cabinet has small animal prevention measures under the condition that the appearance of the switch cabinet is not affected, and air conditioner cooling can be flexibly applied according to the equipment state; and after the channel is completed, each KYN switch cabinet can realize air conditioner refrigeration cooling, so the use flexibility of the KYN switch cabinet is improved.

Description

technical field [0001] The invention belongs to the technical field of cooling and cooling of a circuit breaker chamber of a KYN switch cabinet, and in particular relates to a cooling passage for a circuit breaker chamber of a KYN switch cabinet. Background technique [0002] In recent years, with the increase of power consumption, the load of high-voltage switchgear has gradually increased. When the load is high (generally exceeding 80% of the rated current), the high-voltage switchgear will cause switching The conductor inside the cabinet heats up, even as high as 120°C, which is very likely to cause a short-circuit fault or an explosion. At the same time, the heat will accelerate the aging of the switchgear insulation, conductors and other materials, resulting in hidden dangers in the switchgear, seriously affecting the normal operation of high-voltage equipment, endangering Power grid and personal safety. [0003] There are currently XGN and KYN switchgear types, each a...

Problems solved by technology

At present, the heat dissipation effect of the fan is poor, and the air conditioner can only cool down its environment. The indoor environment of the high-voltage room is large, and the ambient temperature does not drop significantly. The cooling effect of the conductor equipment in the switch cabinet is not obvious. Once the heat dissipation is not good, it will cause Heat generation and even switch cabinet explosion, therefore, this heat dissipation problem needs to be solved urgently
