Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, and more specifically, to a ring network cabinet with a safety mechanism. Background Art

[0002] Ring main unit is a set of electrical transmission and distribution equipment assembled in a metal or non-metallic insulating cabinet or made into an assembled interval ring main unit. Its core part adopts load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in load centers such as urban residential areas, high-rise buildings, large public buildings, factories and enterprises.

[0003] Since there are many electrical devices in the ring network cabinet, and the electrical devices will generate heat when working, in order to avoid the temperature in the ring network cabinet being too high, a ventilation mechanism needs to be set in the ring network cabinet to reduce the temperature inside the ring network cabinet.

[0004] Air circulation must be maintained during ventilation and heat dissipation. During the air circulation process, external humid air will enter the cabinet, corroding the internal electrical equipment and affecting the normal use of parts. In addition, dust in the air adheres to the filter at the air inlet. As the use time increases, the ventilation effect of the air inlet filter attached to dust decreases, resulting in a decrease in air circulation and the inability to ensure ventilation and heat dissipation effects. The service life of electrical equipment will be significantly reduced if it is in a high temperature environment for a long time.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a ring main unit with a safety mechanism. Utility Model Content

[0013] The output shaft of the reciprocating motor drives the screw to rotate. Under the limiting action of the plug rods on both sides, the connecting block produces vertical displacement when it rotates relative to the screw, thereby driving the scraper to move up and down. The fluff on the scraper passes through the gap of the air inlet filter and cleans the air inlet filter from the inside, sweeping off the dust attached to the air inlet filter.

[0014] Preferably, the drying assembly comprises a drying frame, a top frame is sealedly mounted on the top of the drying frame, a lap plate is laid on the surface of the top frame, and a plurality of porous drying sheets are attached to the bottom of the lap plate.

[0015] The porous drying sheet is made of silica gel, montmorillonite, activated carbon and other materials, and has the characteristics of strong moisture absorption, high temperature resistance and not easy to break.

[0016] Preferably, an axial flow fan is mounted on the inner periphery of the air inlet frame via a bracket.

[0017] The axial flow fan is used to drive external air into the air inlet frame of the dust removal component.

[0018] Preferably, a top cover plate is placed on the top of the exhaust frame, and the top cover plate is installed and connected to the exhaust frame by bolts.

[0019] Preferably, the bottom of the porous drying sheet fits with the inner bottom surface of the drying frame.

[0020] The air entering the drying frame needs to pass through multiple porous drying sheets to fully remove moisture from the air.
