Description
Technical Field
The invention relates to power transmission and distribution switch equipment, in particular to a vacuum arc extinguish chamber.
Background
The high-voltage vacuum arc-extinguishing chamber is an electrical device for power supply and distribution, is suitable for a high-voltage power supply and distribution line switch to be used for power distribution and disconnection, is constantly developed towards the aspects of miniaturization, high voltage grade and low cost, and is mostly applied to a circuit breaker. At present, most of vacuum circuit breakers adopt a structure of a vacuum arc extinguish chamber and an operating mechanism. The existing vacuum arc extinguish chamber structure has the defects of complex structure of the operating mechanism, large equipment volume and more moving parts which are easy to break down due to the overhigh precision required by the operating mechanism, and has the defects of limited motion reliability, low sealing property and short service life due to the structural distribution problem.
Disclosure of Invention
The invention aims to solve the technical problem that when the vacuum arc-extinguishing chamber works for a long time, the vacuum arc-extinguishing chamber has low sealing performance and high failure rate due to complex structure, large equipment volume and more moving parts, thereby influencing the service life.
In order to solve the technical problems, the invention provides a vacuum arc-extinguishing chamber, which consists of an exhaust pipe protective cover, epoxy resin filler, a fixed end cover plate, a fixed conducting rod, a shielding cylinder, a shell, a fixed contact, a moving conducting rod, a corrugated pipe, a pressure-equalizing cover, a moving end cover plate and a guide sleeve, wherein one end of the fixed conducting rod is provided with the exhaust pipe protective cover, the other end of the fixed conducting rod is provided with the fixed contact, one end of the moving conducting rod is provided with the guide sleeve, the other end of the moving conducting rod is provided with the moving contact, the axial center lines of the fixed conducting rod and the moving conducting rod are on the same straight line, the fixed end cover plate is wound on the outer ring at the upper end of the fixed conducting rod, the moving end cover plate is wound on the outer ring at the upper end of the moving conducting rod, the shielding cylinder is arranged on the outer rings of the fixed contact and the moving contact, one section and move end cover plate fixed connection, the shell sets up in the shielding section of thick bamboo outer lane, and one end and fixed end cover plate fixed connection, the other end and move end cover plate fixed connection.
Furthermore, the epoxy resin filler is filled in the exhaust pipe protection cover.
Furthermore, the shell is made of ceramic.
After the technical scheme is adopted, the beneficial effects are as follows: when the exhaust pipe protection cover works for a long time, the exhaust pipe protection cover is filled with epoxy resin filler, high sealing performance is guaranteed, the outer ring of the contact is connected with the corrugated pipe in an adaptive mode through the shielding cylinder, the failure rate is reduced, the service life is prolonged, and the shell is made of ceramic and good in insulating performance.
