Abstract
The invention discloses a solid-sealed polar pole for an intelligent vacuum breaker. The solid-sealed polar pole comprises a vacuum arc-extinguishing chamber, an upper outlet conducting end and an epoxy resin casing. A resistance type voltage divider and a vacuum sensor are embedded in the epoxy resin casing, the resistance type voltage divider is in conducting connection with the upper outlet conducting end, a probe of the vacuum sensor is arranged in the vacuum arc-extinguishing chamber, and at a leading-out end of the epoxy resin casing, signal lines of the vacuum sensor and the resistance type voltage divider are jointly arranged at the position of a socket for being connected with a control unit. The vacuum sensor and the resistance type voltage divider can serve as signal acquisition sources of an intelligent controller, the shortcoming that a traditional product is merely an executing mechanism of a whole circuit is overcome, the vacuum sensor can timely and accurately monitor changes of the vacuum degree of the vacuum arc-extinguishing chamber, and using safety of the solid-sealed polar pole for the intelligent vacuum breaker is guaranteed.
Description
Technical field
The invention belongs to the design and fabrication technology field of high-voltage switch equipment, particularly relate to a kind of intelligent solid sealed pole of vacuum circuit breaker.
Background technology
In existing pole, have a kind of such as Chinese patent " a kind of intelligentized AC vacuum circuit-breaker solid sealed arc interrupter pole " (number of patent application CN200610067561.9, September 19 2007 patent disclosure day), this intelligentized AC vacuum circuit-breaker solid sealed arc interrupter pole is mainly by vacuum interrupter, lower outlet conducting end, upper outlet conducting end, shell, the capacitive battery pressure sensor, the signal lead-out wire consists of, be provided with resilient coating between its shell and the vacuum interrupter, shell closely wraps up vacuum interrupter, is enclosed with the capacitive battery pressure sensor in the shell near the skin of vacuum interrupter.There is following point in this intelligent solid sealed pole of vacuum circuit breaker: 1, the capacitive battery pressure sensor belongs to capacitive element, might form resonance with inner inductive element during operation, the overvoltage phenomenon occurs, jeopardizes the normal operation of equipment.When 2, the slight gas leakage of vacuum interrupter caused its vacuum degree to descend, whole intelligent solid sealed pole of vacuum circuit breaker did not have any reaction; When the serious gas leakage of vacuum arc control device causes its vacuum degree to drop to certain value, will cause intelligent solid sealed pole of vacuum circuit breaker contact burn to death can not separating brake fault, will make intelligent solid sealed pole of vacuum circuit breaker general loss ability to work.
Summary of the invention
The object of the present invention is to provide a kind of intelligent solid sealed pole of vacuum circuit breaker, this intelligent solid sealed pole of vacuum circuit breaker inside can solve prior art and have resonance, and vacuum level of vacuum arc-quenching chamber decline causes the problem of whole intelligent solid sealed pole of vacuum circuit breaker disablement.
In order to address the above problem, the technical solution used in the present invention is: this intelligent solid sealed pole of vacuum circuit breaker, comprise vacuum interrupter, upper outlet conducting end, epoxy package, be embedded with resistance divider and vacuum transducer in the described epoxy package, described resistance divider is connected with described upper outlet conducting end conduction, it is indoor that the probe of described vacuum transducer is arranged on described vacuum extinction, described resistance divider be connected the holding wire of vacuum transducer and be used for the socket position that is connected with control unit at the exit of described epoxy package with being located at one.
In the above-mentioned intelligent solid sealed pole of vacuum circuit breaker technical scheme, technical scheme can also be more specifically: described resistance divider and described vacuum transducer outside all are coated with silastic-layer.
Owing to adopted such scheme, the present invention compared with prior art has following beneficial effect:
1, adopt resistance divider, do not have resonance problems, performance is better than the capacitive battery pressure sensor, has higher reliability;
2, poured into a mould vacuum transducer in the indoor increase of vacuum extinction, timely and accurately vacuum interrupter is carried out vacuum-degree monitoring, whether its vacuum degree of Real-Time Monitoring meets safety requirements, significant to improving the vacuum interrupter reliability of operation, guaranteed the use safety of whole intelligent solid sealed pole of vacuum circuit breaker;
3, resistance divider and vacuum transducer carry out poured with epoxy resin after all processing through silicon rubber vulcanization in advance again, and silicon rubber intensity is high, good springiness, and good electrical insulating property is arranged, and has not only exempted the stress infringement, has also improved integral insulation.
