Abstract

The invention discloses an environmentally-friendly type switch body, comprising: a pre-installed type vacuum circuit breaker / vacuum load switch pole, a spindle box, a three-position isolated grounding switch, an insulation beam, and a switch body frame. The pre-installed type vacuum circuit breaker / vacuum load switch pole, the three-position isolated grounding switch, and the insulation beam are plastic components through the injection molding of thermoplastic engineering plastics. The spindle box and the switch body frame are assembled by carbon steel plates. The utilization of clean gas as the insulation medium prevents the pollution to the environment. The parts and components inside the switch body can be recycled, reducing the waste and conserving energy. The modularized design of the inner components of the switch body means that the detachment is convenient and that the production efficiency is increased.

Description

technical field [0001] The invention relates to a ring network cabinet switch, in particular to an environment-friendly switch body. Background technique [0002] The ring network cabinet is a set of switchgear installed in a steel plate metal cabinet or other forms of electrical equipment. It has the advantages of small size, simple structure, low price, adjustable electrical parameters and performance, and power supply safety. It mainly includes gas-insulated ring network cabinets. and solid insulated ring network cabinets. [0003] In the prior art, most gas-insulated ring network cabinets use SF6 gas as the insulating medium, and SF6 is listed as one of the six gases with greenhouse effect, and will be decomposed into toxic and harmful gases under high-temperature arc. Therefore, reducing or avoiding the use of SF6 gas has become an inevitable trend in the development of the switchgear industry. [0004] Ring network cabinets are mainly gas-insulated and solid-insulate...
