Vacuum interrupter has a very important precondition, must ensure that in it must be vacuum state exactly, and for ensureing the vacuum state of vacuum interrupter in prior art, airtight insulation crust, moved end cover plate, the fixed end cover plate that all can be made up of glass or pottery, constitute airtight insulation system.
Vacuum circuit-breaker arc extinguishing chamber vacuum degree must not lower than 6.62 × 10-2Pa.Otherwise its connecting-disconnecting function and withstand voltage level can be affected.The reason that vacuum level of vacuum arc-quenching chamber reduces mainly arc control device gas leakage.At present, more feasible and practical detection in it means of vacuum degree have: ac voltage withstanding method, it is a kind of more simple and effective detection method that this method is in operation.But this method but want regularly to circuit breaker major loop over the ground, alternate and fracture carries out AC voltage withstand test, just indication information can not be sent voluntarily when vacuum interrupter leaks air phenomenon at the beginning, just diverged to the time detected if gas leakage occurs vacuum interrupter, that is when vacuum interrupter generation gas leak phenomenon, high-tension circuit can not blow-out suppress electric current rapidly after cutting off the electricity supply, increase accident and the unexpected danger occurred, but do not have corresponding solution to above-mentioned technical problem in prior art.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is whether provide a kind of directly can occur a kind of vacuum interrupter of gas leakage by observe and decide.
For achieving the above object, the utility model provides following technical scheme: a kind of vacuum interrupter, comprise vacuum interrupter body, the airtight insulation crust of described vacuum interrupter body offers through hole, through hole is connected with gas leakage indication piece, described gas leakage indication piece includes and becomes L shape to be formed by connecting by two sections of siphunculus and two ends is the pipeline of closed state, the diaphragm of closed conduct one end and indicator solution, one section of indication piece of wherein leaking gas is arranged in through hole, another section fits in airtight insulation crust, diaphragm closes the termination being connected to pipeline relative vacuum arc control device inside, indicator solution is stored in pipeline.
By adopting technique scheme, because described vacuum interrupter offers through hole at the airtight insulation crust place of its airtight insulation system, and described through hole connects gas leakage indication piece, so just can be reflected by gas leakage indication piece timely once described vacuum interrupter generation gas leak phenomenon, the operational observations of handled easily personnel, strengthen the fail safe of vacuum interrupter, and in the utility model, described gas leakage indication piece includes and becomes L shape to be formed by connecting by two sections of siphunculus and two ends is the pipeline of closed state, the diaphragm of closed conduct one end, elastic component and indicator solution, one section of indication piece of wherein leaking gas is arranged in through hole, another section fits in airtight insulation crust, diaphragm closes the termination being connected to pipeline relative vacuum arc control device inside, indicator solution is stored in pipeline, air pressure due to vacuum extinction chamber interior be less than normobaric, so diaphragm is meeting protruding externally to vacuum extinction chamber interior by vacuum interrupter, that horizontal plane being stored in the indicator solution of indication piece inside will be lower, and when gas leakage occurs vacuum interrupter, air pressure so in it will be identical with atmospheric gas pressure, diaphragm can recover normal condition, the horizontal plane of the indicator solution so in device and indication piece will lifting, gas leak phenomenon is there occurs so as to its vacuum interrupter of prompting operator, adopt said structure, the technique effect required by the utility model can not only be realized well, and its structure is simple, processing cost is low.
The utility model is set to further: described pipeline and airtight insulation crust one section of fitting is transparent material, and is marked with Warning Mark.
By adopting technique scheme, only have and adopt transparent material, directly could show the horizontal plane state of device and the inner indicator solution of indication piece more clearly, so as to allowing, operator is more convenient to be observed, so as to judging, and arrange on its surface to mark observation process just can be made more intuitively short and sweet.
The utility model is set to further: described diaphragm is that 65Mn material is made.
By adopting technique scheme, employing 65Mn is not only well positioned to meet the technique effect required by the utility model, and 65Mn is more high temperature resistant well can adapt to the higher environment of the indoor temperature of vacuum extinction, its rebound performance is also better, and be fixed the technique effect closed and be also well positioned to meet closed conduit one end with one end of indication piece.
The utility model is set to further: described indicating liquid has certain color.
By adopting technique scheme, allow indicator solution have certain gay colours, directly could show the horizontal plane state of device and the inner indicator solution of indication piece more clearly, so as to allowing, operator is more convenient to be observed, so as to judging.
