A central cabinet with good cooling and heat dissipation effect

Abstract

The invention belongs to the technical field of central cabinets, and specifically relates to a central cabinet with good cooling and heat dissipation effects, including a cabinet body, which includes a relay instrument room, a circuit breaker handcart room, a bus room and a cable room, and a circuit breaker handcart room. The vehicle compartment is equipped with a contact box, and the relay instrument room is equipped with a first partition. The first partition includes a first horizontal plate and a first vertical plate. The first horizontal plate and the first vertical plate are hollow inside and communicate with each other to form a second One air duct, the circuit breaker handcart room is provided with a second partition, the second partition includes a second horizontal plate, a third horizontal plate and a second vertical plate, the second horizontal plate, the third horizontal plate and the second vertical plate The boards are hollow inside and communicate with each other to form the second air duct. The handcart room of the circuit breaker is provided with a third partition. The third partition includes a fourth horizontal board and a third vertical board. The inside of the fourth horizontal board and the third vertical board Hollow and interconnected to form a third air channel, the busbar room is provided with a fourth partition, the cable room is provided with a base, the base is provided with a cavity, and the front side of the cavity is provided with an exhaust groove.

Description

technical field [0001] The invention belongs to the technical field of central cabinets, and in particular relates to a central cabinet with good cooling and heat dissipation effects. Background technique [0002] The central cabinet, the full name of the metal armored central removable switchgear, is often used for high-voltage power distribution. Its structural composition includes the upper relay instrument room, the middle circuit breaker handcart room and busbar room, and the lower layer. The cable rooms are separated by partitions. Since the handcart room of the circuit breaker is in the middle layer, it is called the armored type removable central metal-enclosed switchgear, referred to as the central cabinet. The central cabinet is mainly used In power plants, power transmission of small and medium-sized generators, power reception and transmission of secondary substations in power systems, power distribution of industrial and mining enterprises, and starting of large...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a central cabinet with good cooling and heat dissipation effect, so as to solve the problem that the existing central cabinet usually uses a simple fan for heat dissipation, and cannot sufficiently cool and radiate the contact box, and the central cabinet The cabinet does not have a separate air duct structure, so that the internal heat dissipation is not comprehensive and sufficient, resulting in the problem that the overall cooling effect of the central cabinet is not good
