Sulfur hexafluoride insulated inflatable ring main unit

Abstract

The invention discloses a sulfur hexafluoride insulated inflatable ring main unit. The ring main unit comprises a cabinet body, and a cabinet door is arranged on the front side of the cabinet body; and the cabinet body is provided with an air cavity and a cavity. Vertically-arranged supporting legs are slidably connected to the four corners of the bottom of the cabinet body; an air box is arrangedat the top of the inner side of the cavity; one end of a bent pipe is fixedly connected to each of two sides of the air box, and the other end of the bend pipe communicates with the air cavity; a motor is fixedly connected to the inner wall of one side of the cavity, an output shaft of the motor is fixedly sleeved with a first fan blade, two rotary discs and multiple sets of second fan blades, the multiple sets of second fan blades are all located on the inner side of the air box, the air box is located between the two rotary discs, and the first fan blades are located on the outer side of the air box. The sulfur hexafluoride gas circulation flowing effect is improved, heat dissipation is facilitated, the temperature in the ring main unit is reduced, the wheels on the ring main unit supporting legs can ascend and descend freely by means of power of the motors, and the ring main unit can be transferred conveniently in a labor-saving mode.

Description

technical field [0001] The invention relates to the technical field of ring network cabinets, in particular to a sulfur hexafluoride insulated inflatable ring network cabinet. Background technique [0002] The ring network cabinet is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has a structure Simple, small size, low price, can improve power supply parameters and performance, and power supply security and other advantages. After retrieval, the Chinese patent with the authorized announcement number CN209948470U discloses a sulfur hexafluoride insulated inflatable ring network cabinet, including a cabinet body, a base is installed on the bottom of the cabinet, and four liftable lifters are installed on the inner top wall of the base. Mounting frame, the bottom of the mou...

Problems solved by technology

[0003] However, the flow effect of the insulating gas in the existing ring network cabinet is relatively poor, which is not conducive to heat dissipation, and it is easy to cause overheating and damage to the electrical components inside the ring network cabinet, and the existing ring network cabinet is too heavy for position transfer, so we propose six Sulfur fluoride insulated inflatable ring network cabinet is used to solve the above problems
