High-pressure vacuum breakers all types of in the current domestic and international power industry are in the operation of different model switching control device is used, the fault that a lot of equipment caused or have the accidents caused point of possibility and mainly contain two places: the one, breaker body connects incision position with electric conductor, because dynamic and static contact variance factor is many, the change of conduction resistance is big, and the fast heating of temperature rise is serious; The 2nd, folding incision position in the vacuum tube, through dynamic and static contact wearing and tearing after one section operation, loose contact influences three-phase same period, and can cause the transient operation overvoltage.How to overcome the deficiencies in the prior art, improve the useful life and the fault alarm of vacuum circuit-breaker, become the key problem in technology of novel high-pressure vacuum breaker.
The utility model content
Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art, a kind of intelligent high-pressure vacuum breaker is provided, it can detect vacuum circuit breaker body timely and accurately and connect folding incision position contact head abrasive loss in incision position temperature change situation and the vacuum tube with electric conductor, realize online detection and fault alarm, improve product useful life and reduced accident generator rate.
The purpose of this utility model is achieved through the following technical solutions: a kind of intelligent high-pressure vacuum breaker, comprise three arc interrupter poles, upper bracket and lower carriage are arranged on each arc interrupter pole, in each arc interrupter pole vacuum interrupter is arranged, vacuum extinction is indoor moving conductive rod, it is characterized in that: temperature transducer is installed at the upper bracket of each arc interrupter pole and the incision position of lower carriage, at the indoor installation contact wearing and tearing of each vacuum extinction induction installation, this contact wearing and tearing induction installation comprises incident light source, reflector and light source are accepted transducer, described reflector leans against on the described moving conductive rod and around a pivoted, described incident light source and light source are accepted the reflecting surface setting of transducer with respect to reflecting plate, incident light source is radiated on the reflector, and reverberation shines light source and accepts on the transducer; Six temperature transducers and three light sources are accepted transducer and are connected on the central processing unit by input circuit, and the central processing unit signal output part is connected with the Surveillance center computer.
Described incident light source is a lasing light emitter.
The utility model compared with prior art has following advantage: it can implement fracture temperature rise on-line monitoring and control in real time to breaker body and external interface; The automatic detection that the contact head abrasive loss of vacuum interrupter has been realized and reporting to the police automatically.Detection information for two kinds of transducers is carried out data processing by central processing unit, can be connected with the Surveillance center computer by wired and wireless network, can realize intelligentized operational management.Several key technical index that influence system equipment safety in the circuit breaker on-line operation process are accomplished effectively to detect and advance notice; And can realize urgent locking and tripping operation where necessary to circuit breaker.Thereby the fail safe and the reliability that have strengthened breaker body and the switchgear of body is installed.
