Description

Maintenance-free anti-pollution flashover anti-condensation external insulating part and production method thereof
Technical Field
The invention relates to the technical field of high-voltage electrical equipment, in particular to a maintenance-free anti-pollution flashover anti-condensation external insulating part and a production method thereof.
Background
At present, a high-voltage switch cabinet is used as electric energy distribution equipment, and plays a very important role in the operation of a power grid, and the insulation capacity of the high-voltage switch cabinet is an important factor for whether the high-voltage switch cabinet can safely and stably operate. The insulating capability of the high-voltage switch cabinet has the influence factors of temperature, humidity, condensation and the like of the operating environment in the cabinet besides the influence factors of design, materials and quality of the high-voltage switch cabinet. In actual operation of a high-voltage switch cabinet, insulation accidents of the high-voltage switch cabinet frequently occur due to severe environmental factors such as temperature, humidity and condensation of an operation environment in the cabinet.
The outer insulating part is one of main insulating parts of high-voltage electrical switchgear, is used for insulating and protecting the connection of high-voltage electrical appliances among compartments in a high-voltage switch cabinet, and is mainly used in transformer substations, power distribution devices and high-voltage electrical appliances. When the conductive piece penetrates through a wall or other grounding objects, the outer insulating piece plays a role in supporting and insulating, the outer insulating piece can be a wall penetrating sleeve or a contact box and the like, and the conductive piece can be a conductive piece and the like. At present, a high-voltage switch cabinet is developed into a totally-enclosed, totally-insulated and miniaturized indoor high-voltage complete switch device in China, and the application of an external insulating part in the switch cabinet is increased. Due to different climatic environments and use scenes, the discharge problem caused by the phenomena of dirt, condensation, water accumulation and the like often occurs. Specifically, since the external insulating member is generally installed in a transverse direction, condensation and water accumulation (difficult to discharge) are likely to occur on the inner wall of the external insulating member at positions corresponding to the inlet and the outlet of the conductive member, and the generated water accumulation may cause a floating potential, which may cause partial discharge and surface discharge. According to statistics, the discharge phenomenon is relatively common on the switching equipment with the voltage level of 10-40.5kV, and the harm brought by the discharge phenomenon is shown as follows:
1. the high energy generated in the discharge process can ionize oxygen in the air to generate O 3 、NO、NO 2 The insulating material has strong oxidizability after being dissolved in water, so that the aging of the insulating material is accelerated, and a discharge area is diffused;
2. long-term gas discharge can cause electrical energy loss;
3. the long-term gas discharge is easy to cause the insulation thermal breakdown of the outer insulator;
4. and the aging and performance reduction of the external insulating part are easily caused, and the interphase short circuit and even the explosion of the high-voltage switch cabinet are caused by the breakdown discharge.
Therefore, we propose a maintenance-free anti-pollution flashover and anti-condensation external insulator, a production method thereof and a method for eliminating the discharge phenomenon.
