Abstract
The utility model discloses an intelligentized vacuum circuit breaker solid-sealed polar pole which comprises a vacuum arc-extinguishing chamber, an upper outgoing line conducting end and an epoxy resin casing. A resistance-type voltage divider and a vacuum sensor are embedded into the epoxy resin casing, the resistance-type voltage divider is in conducting connection with the upper outgoing line conducting end, a probe of the vacuum sensor is arranged in the vacuum arc-extinguishing chamber, and the resistance-type voltage divider and a signal line of the vacuum sensor are arranged at the socket position for controlling unit connection at the leading-out end of the epoxy resin casing. The vacuum sensor and the resistance-type voltage divider can serve as signal acquiring sources of an intelligent controller, and the shortcoming that a traditional product only serves as one actuating mechanism in a complete circuit is overcome. The vacuum sensor timely and accurately monitors changes of the vacuum arc-extinguishing chamber and guarantees the safety of the intelligentized vacuum circuit breaker solid-sealed polar pole in use.
Description
Technical field
The utility model belongs to the design and fabrication technology field of high-voltage switch equipment, particularly relates to a kind of intelligent solid sealed pole of vacuum circuit breaker.
Background technology
In existing pole, have a kind of as Chinese patent " a kind of intelligentized AC vacuum circuit-breaker solid sealed arc interrupter pole " (number of patent application CN200610067561.9, patent is day on September 19th, 2007 openly), 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 forms, be provided with resilient coating between its shell and vacuum interrupter, shell closely wraps up vacuum interrupter, be enclosed with the capacitive battery pressure sensor in 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, during operation, likely can form resonance with inner inductive element, the overvoltage phenomenon occurs, jeopardizes the normal operation of equipment.When 2, the slight gas leakage of vacuum interrupter causes its vacuum degree to descend, whole intelligent solid sealed pole of vacuum circuit breaker does 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.
The utility model content
The purpose of this utility model 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 adopted in the utility model 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 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, the holding wire of described resistance divider and described vacuum transducer is located at together a socket position for being connected with control unit at the exit of described epoxy package.
In 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 having adopted such scheme, the utility model 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 to 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 all carry out poured with epoxy resin in advance after silicon rubber vulcanization is processed 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.

Embodiment
Below in conjunction with the accompanying drawing example, the utility model is described in further detail.
In the accompanying drawing explanation, the intelligent solid sealed pole of vacuum circuit breaker shown in Fig. 1 has vacuum interrupter 3, lower outlet conducting end 1, upper outlet conducting end 4, epoxy package 2.Be provided with resilient coating between epoxy package 2 and vacuum interrupter 3, vacuum interrupter 3, upper outlet conducting end 4 and lower outlet conducting end 1 use epoxy resin adopt pressure gel technique moulding by casting; Be embedded with resistance divider 7 and vacuum transducer 9 in epoxy package 2, resistance divider 7 is positioned near outlet conducting end 4, and wherein an end wire is connected on outlet conducting end 4, and other end wire is that holding wire 10 is drawn; The probe of vacuum transducer 9 is arranged in vacuum interrupter 3, and the electric signal of vacuum transducer is drawn through holding wire 10, and two holding wires are located at together a socket position for being connected with control unit at the exit of epoxy package 2.Resistance divider 7 and vacuum transducer 9 carry out poured with epoxy resin after all having anticipated silastic-layer 8 again; Epoxy package 2 is sealed all parts to be cast for a whole pole.
