A central high and low cabinet with good heat dissipation and dust removal performance

Abstract

The invention discloses a centrally-installed switchgear with good heat dissipation and dust removing performance. The switchgear comprises a cabinet body and a support seat arranged under the cabinetbody. The support seat is fixedly connected with the cabinet body through multiple connection columns. The cabinet body is of a cylindrical cylinder body. Air discharging openings are uniformly distributed in the surface of outer side of the cabinet body. An air guiding cylinder is arranged in the middle position in the cabinet body. Air passing holes are uniformly distributed in the surface of the air guiding cylinder. An air charging guiding pipe is arranged at a lower port of the air guiding cylinder. According to the invention the switchgear is simple and proper in structure, and by setting the air guiding cylinder in the middle position of the cabinet body, air radiates and is dissipated away all around from the surface of the air guiding cylinder under the function of blades, so heat in the cabinet body is blown out from the air discharging holes, thereby achieving discharging of the heat in the cabinet body. In this way, an air exchange path is shortened; rapid discharging of the heat is facilitated; and the switchgear has a dust removing function, so a problem that dust is collected in the cabinet body is avoided.

Description

Technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a middle high-low cabinet with good heat dissipation and dust removal performance. Background technique [0002] The center cabinet is called the metal armored center removable switchgear. It is a high-voltage power distribution device with a maximum operating voltage of 3.6 / 7.2 / 12kV. It is an indoor complete power distribution device for a three-phase AC 50Hz single-bus section system or a double-bus section system. It is used for receiving and distributing 3.6-12kV network electric energy, and controlling, protecting, monitoring and measuring the power circuit. Mid-mounted switchgear is mainly used for power plants, transmission of small and medium-sized generators, power reception and transmission of secondary substations of power systems, power distribution of industrial and mining enterprises and institutions, and starting of large high-voltage motors.

Problems solved by technology

[0003] In the prior art, the central cabinet is used as a power distribution device. During normal operation, due to the large number of internal circuits, the circulation is poor, which leads to the inability to dissipate heat, and the problem of dust collection is prone to occur inside the cabinet. In summary, As mentioned above, there is an urgent need for a middle high and low cabinet with good heat dissipation and dust removal performance to solve the above problems
