Environment-friendly insulating ring main unit

Abstract

The invention discloses an environment-friendly insulating ring main unit, which comprises a cabinet body and a door plate installed on the cabinet body. An insulating gas storage chamber is arranged in the cabinet body, a communicating pipe is slidably arranged in the insulating gas storage chamber in a penetrating manner, and two groups of vertically distributed ventilation assemblies are arranged in the communicating pipe in a penetrating manner. And the top end of the interior of the insulating gas storage chamber is further rotationally connected with a rotary sleeve for driving the communicating pipe to vertically move, the output end of the gas pump communicates with a gas pipe, and the output end of the gas pipe communicates with the input end of the shaft sleeve. According to the device, the gas pump is started to enable the insulating gas storage chamber to be in a negative pressure state, when the set of ventilation components located on the lower side stretch out of the insulating gas storage chamber, the insulating gas SF6 is sucked into the insulating gas storage chamber through the hole grooves, and the insulating gas SF6 is absorbed in advance, so that the environment protection is facilitated, the maintenance personnel can be in a safe working environment, and the use safety and reliability of the ring main unit are improved.

Description

technical field [0001] The invention relates to the technical field of ring network cabinets, in particular to an environment-friendly insulating ring network cabinet. Background technique [0002] The ring network cabinet is a group of transmission and distribution electrical equipment (high-voltage switchgear), which is 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. The utility model has the advantages of simple structure, small size, low price, can improve power supply parameters and performance, and power supply security. [0003] In order to ensure the stable operation of the energized parts in the ring network cabinet, most of them will fill the cabinet with an appropriate amount of insulating gas to extinguish the arc of the electrical components in operation. Due to the high stability of SF6 gas, it is currently on the market Most of the current ring n...

Problems solved by technology

[0003] In order to ensure the stable operation of the energized parts in the ring network cabinet, most of them will fill the cabinet with an appropriate amount of insulating gas to extinguish the arc of the electrical components in operation. Due to the high stability of SF6 gas, it is currently on the market Most of the current ring network cabinets use SF6 gas as the arc extinguishing medium. However, the existing ring network cabinets do not have the equipment for storing the insulating gas. When the corresponding personnel need to open the ring network cabinet to maintain the electrical components in the cabinet, they will The leakage of the insulating gas in the cabinet will not only affect the environment, but the high concentration of SF6 gas will also cause the maintenance personnel to have difficulty breathing, panting, blue skin and mucous membranes, and body spasm, which is not conducive to the corresponding maintenance work
