Abstract

The invention discloses a KNY28 centrally installed switchgear with a dehumidification function and an anti-tripping function, the KNY28 centrally installed switchgear comprises a centrally installed switchgear body, a working box and a ventilation frame, the back of the centrally installed switchgear body is provided with the working box, the bottom of one side of the centrally installed switchgear body is provided with the ventilation frame, and the ventilation frame is internally provided with two groups of cooling fans; and a ventilation groove is formed in the middle of the top of the working box. According to the invention, through the arrangement of the placement box, when a worker needs to dehumidify the interior of the centrally installed switchgear body, the ventilation slots and the ventilation strips are matched for use, so that air in the centrally installed switchgear body can keep good fluidity, and a dustproof net can prevent external dust from falling into the device; and after the switch cover is opened, a proper adsorbent is added into the placing box, the adsorbent can absorb moisture in the centrally installed switchgear body according to the characteristics of the adsorbent, the hollowed-out net can make the adsorbent better make contact with the moisture in the centrally installed switchgear body, so that the moisture is absorbed, and then the interior of the centrally installed switchgear body can be dehumidified.

Description

technical field [0001] The invention relates to the technical field of central cabinets, in particular to a KNY28 central cabinet with dehumidification and anti-jump functions. Background technique [0002] The full name of the central cabinet is the armored type removable central metal-enclosed switchgear, which is divided into three layers. The upper layer is the busbar and instrument room, the middle layer is the circuit breaker room, and the lower layer is the cable room. Therefore, it is called the armored type central metal enclosed switchgear, referred to as the central cabinet. [0003] The defects of an existing KNY28 central cabinet are: [0004] 1. The comparative document CN206820263U discloses a central cabinet with a dehumidification device, "including a central cabinet body, a cabinet door, feet, and a handle, the cabinet door is connected to the front face of the central cabinet body through hinges, and the lower end surface of the cabinet door is provided w...
