Abstract
The utility model discloses a sealing structure of a gas-filled circuit breaker. The sealing structure comprises a shell, an opening at one side end of the shell is sealed by an end cover; six outlet pole ports and a control circuit are arranged on the shell and sealed by the end cover; the combination parts of the end cover with the shell and the six outlet pole ports are sealed by two-stage sealing rings made of different materials; and the material can be rubber or silica gel for the purpose of reinforcing the sealing effect and prolonging the service life. In addition, the combination part of a transmission rod of the shell and the shell wall is sealed in double layers by different materials. The sealing structure has the advantages of good sealing performance of the shell, reasonable structure, safety and reliability, etc.
Description
Technical field
The utility model discloses a kind of gas filling circuit breaker seal construction, divides by International Patent Classification (IPC) (IPC) to belong to circuit breaker manufacturing technology field, especially relates to a kind of Threephase common-box gas-filled type Shell of circuit breaker hermetically-sealed construction of outdoor use.
Background technology
Circuit breaker is divided into primary cut-out and low-voltage circuit breaker by its scope of application, and wherein, primary cut-out (or claiming high-pressure vacuum switch) is divided into three-phase discrete and Threephase common-box by the structure construction form; Be electric control appliance main in the power transmission and transformation line, when electric power system normally moved, it can cut off and connect the zero load and the load current of circuit and various electric equipments; When system broke down, it cooperated with the relaying protection control circuit, cutting-off of short-circuit fault current rapidly, and preventing expansion accident scope, so the quality of primary cut-out work, directly have influence on the safe operation of electric power system.
Existing gas filling circuit breaker generally is between breaker body and its shell, to be filled with the sulphur hexafluoride (SF6) with insulation function, to improve its arc extinguishing function and security performance.At present, the end cap of circuit breaker, pole and housing are to fasten as one through screw, and both junctions have only a sealing ring, and its sealing property is relatively poor, and therefore, the sealing problem of case for circuit breaker is the producer's technical problem that need improve and improve in the industry.
Summary of the invention
To the deficiency of prior art, the utility model provides a kind of rational in infrastructure, safe and reliable gas filling circuit breaker seal construction.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of gas filling circuit breaker seal construction; Its housing one side opening is by end cap seal, and housing is provided with six outlet pole ports and three control circuit end cap seal, it is characterized in that: described end cap and housing junction and six two-stage seal ring seals that outlet pole port junction all adopts to be processed by unlike material; The two-stage sealing ring selects for use unlike material to process respectively; Material can be selected rubber or silica gel for use, and purpose is to strengthen sealing effectiveness, increases the service life.
Further, at least one is cavity ring for described two-stage sealing ring, and the two-stage sealing ring is rubber ring and the falope ring that unlike material is processed into.
Further, be provided with two-stage rubber ring and falope ring in described end cap and the housing junction twice ring-shaped groove.
Further, described housing is provided with the drive link of control circuit breaker, and the double-layer seal ring sealing of unlike material is adopted in itself and housing wall junction.
The utility model discloses a kind of gas filling circuit breaker seal construction; Comprise housing; Housing one side opening is by end cap seal, and housing is provided with six outlet pole ports and control circuit outlet end cap seal, wherein: end cap and housing junction and six two-stage seal ring seals that outlet pole port junction all adopts to be processed by unlike material; Avoid the effusion phenomenon of sulphur hexafluoride (SF6) gas in the circuit breaker; In addition, the double-layer seal of unlike material is adopted in the drive link of housing and housing wall junction, the utlity model has advantages such as the housing seal performance is good, rational in infrastructure, safe and reliable.
