Outgoing bus device

Abstract

The invention discloses an outlet bus bar device which comprises an outlet casing pipe, a bus bar body and a bus bar gland, wherein the outlet casing pipe is connected to one end of the bus bar body, the bus bar gland is connected to the other end of the bus bar body, the bus bar body comprises a conductive rod as well as a conductive layer, a silicone rubber layer and a semi-conductor layer which are sequentially arranged outside the conductive rod, and every two adjacent layers are mutually bond. The outlet bus bar device provided by the invention is not liable to crack, and is safe and reliable in a using process; the electric field distribution is more uniform, local discharge can be prevented, the assembly is simple and convenient, preassembly can be performed in advance to realize modular assembly, and the production efficiency is improved.

Description

technical field [0001] The invention relates to an electric appliance, in particular to an outgoing busbar system used on a solid insulation ring network cabinet. Background technique [0002] At present, the insulation layer of the outgoing busbar of the solid insulated ring main unit in the market is mostly epoxy resin. The epoxy resin has good insulation performance but insufficient toughness. When it is stressed, it is prone to cracking, which reduces the insulation performance, leads to safety accidents, and even endangers operation. The personal safety of workers; in addition, epoxy resin castings not only pollute the environment during the production process, but also epoxy resin cannot be degraded, it is difficult to recycle at the end of its life, and long-term use has a great impact on the environment; moreover, most Epoxy resin coatings are solvent-based coatings, which contain a large amount of volatile organic compounds (VOC), which are toxic and flammable, and ...

[0002] At present, the insulation layer of the outgoing busbar of the solid insulated ring main unit in the market is mostly epoxy resin. The epoxy resin has good insulation performance but insufficient toughness. When it is stressed, it is prone to cracking, which reduces the insulation performance, leads to safety accidents, and even endangers operation. The personal safety of workers; in addition, epoxy resin castings not only pollute the environment during the production process, but also epoxy resin cannot be degraded, it is difficult to recycle at the end of its life, and long-term use has a great impact on the environment; moreover, most Epoxy resin coatings are solvent-based coatings, which contain a large amount of volatile organic compounds (VOC), which are toxic and flammable, and will cause harm to the environment and human body during use

The outgoing busbar cannot be grounded due to structural limitations, and the electric field is unevenly distributed, prone to partial discharge, and there are potential safety hazards in long-term operation
