Description

Insulating pressure vessel
Technical Field
The utility model relates to a high voltage test technical field, specifically speaking especially relates to an insulating pressure vessel that is used for vacuum interrupter to smelt technology always.
Background
In a high-voltage transmission line, a loaded switching circuit is needed, electric arcs can be generated between two contacts during switching, the metal on the surfaces of the contacts can be ablated by the electric arcs, and the contacts are damaged, so that the electric arcs are very important to be extinguished as soon as possible during switching of the circuit. Air dielectric insulation or heavy oil dielectric insulation is used as arc extinction in the early period, but the electric arc ionizes air or decomposes heavy oil to generate carbon atoms, which greatly influences insulation. The vacuum arc-extinguishing chamber is mostly adopted as a switch, and the vacuum switch has the advantages of small volume, less maintenance and the like.
In the production process of the vacuum arc-extinguishing chamber, a burn-in process is provided, namely, a high-voltage power frequency voltage is added between the contacts which are separated by a certain distance, so that electric arcs are generated between the two contacts, and after burrs on the surfaces of the contacts are ablated by the electric arcs, the surfaces of the contacts are smooth, and the burn-in process is completed. In the aging process, the vacuum arc-extinguishing chamber needs to be placed in an environment surrounded by an insulating medium, and the high voltage loaded at two ends of a contact of the vacuum arc-extinguishing chamber is prevented from creeping and breaking down along a shell of the vacuum arc-extinguishing chamber, so that the aging process of the vacuum arc-extinguishing chamber cannot be completed.
At the earliest, the aging of vacuum interrupters was carried out in an insulating liquid like freon. The liquid generally has the volatilization characteristic, is a greenhouse gas and does not meet the environmental protection requirement. Moreover, after the aging of the vacuum arc-extinguishing chamber is finished, the liquid attached to the surface of the vacuum arc-extinguishing chamber needs to be wiped or blown clean, so that a large amount of greenhouse gas is leaked into the air, and the health of operators is not facilitated.
Along with the popularization of automated production, original manual ageing process is replaced by automatic ageing assembly line, in automatic ageing assembly line, smelts the vacuum interrupter of more than 5 quantity simultaneously, and original technology that uses freon liquid insulation also can not adapt to modern production, changes into and uses compressed air as the surface insulation of vacuum interrupter, and compressed air's pressure must reach more than 0.35 MPa.
When the vacuum arc-extinguishing chamber is used for aging at high-voltage power frequency, the whole vacuum arc-extinguishing chamber is placed in a container which takes an insulating material as a main body, the inside of the container is filled with compressed gas, and the compressed gas has the effect of enhancing the surface insulation of the vacuum arc-extinguishing chamber. The container is filled with compressed gas before the aging process, the gas is exhausted after the aging process is completed, the container is opened, the container is moved aside, the vacuum arc-extinguishing chamber is convenient to take out, in order to quickly close or open the container, the mechanical structure needs to be simply and quickly locked and loosened, the force generated by the fact that the inside is filled with the compressed gas can be borne, and therefore the insulating pressure container which can be quickly opened and closed and can bear the pressure is needed.
