Abstract
The invention discloses a kind of intelligent vacuum circuit breaker pole, comprise vacuum interrupter, upper outlet conducting end, epoxy package, resistance divider and vacuum transducer is embedded with in described epoxy package, described resistance divider conducts electricity with described upper outlet conducting end and is connected, the probe of described vacuum transducer is arranged on described vacuum extinction indoor, and described resistance divider is located at a socket position for being connected with control unit with the holding wire of described vacuum transducer together at the exit of described epoxy package.Vacuum transducer of the present invention and resistance divider can be used as the signals collecting source of intelligent controller, overcome the shortcoming that traditional product is only an actuator in complete circuit; Vacuum transducer monitors the change of vacuum level of vacuum arc-quenching chamber timely and accurately, ensure that the use safety of intelligent vacuum circuit breaker pole.
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 vacuum circuit breaker pole.
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 publication date on September 19th, 2007), this intelligentized AC vacuum circuit-breaker solid sealed arc interrupter pole is primarily of vacuum interrupter, lower outlet conducting end, upper outlet conducting end, shell, capacitive battery pressure sensor, signal lead-out wire is formed, resilient coating is provided with between its shell and vacuum interrupter, vacuum interrupter closely wraps up by shell, near the skin of vacuum interrupter, capacitive battery pressure sensor is enclosed with in shell.There is following point in this intelligent vacuum circuit breaker pole: 1, capacitive battery pressure sensor belongs to capacitive element, likely can form resonance with inner inductive element, occur overvoltage phenomenon, jeopardize the normal operation of equipment during operation.2, when vacuum interrupter slightly leaks gas and causes its vacuum degree to decline, whole intelligent vacuum circuit breaker pole does not have any reaction; When vacuum interrupter seriously leak gas cause its vacuum degree to drop to certain value time, intelligent vacuum circuit breaker pole contact will be caused to burn to death can not the fault of separating brake, will make intelligent vacuum circuit breaker pole general loss ability to work.
Summary of the invention
The object of the present invention is to provide a kind of intelligent vacuum circuit breaker pole, this intelligent vacuum circuit breaker pole inside can solve prior art and there is resonance, and vacuum level of vacuum arc-quenching chamber decline causes the problem of whole intelligent vacuum circuit breaker pole disablement.
In order to solve the problem, the technical solution used in the present invention is: this intelligent vacuum circuit breaker pole, comprise vacuum interrupter, upper outlet conducting end, epoxy package, resistance divider and vacuum transducer is embedded with in described epoxy package, described resistance divider conducts electricity with described upper outlet conducting end and is connected, the probe of described vacuum transducer is arranged on described vacuum extinction indoor, described resistance divider is located at a socket position for being connected with control unit with the holding wire of described vacuum transducer together at the exit of described epoxy package.
In above-mentioned intelligent vacuum circuit breaker pole technical scheme, technical scheme can also be more specifically: described resistance divider and described vacuum transducer outside are all coated with silastic-layer.
Owing to have employed such scheme, the present invention compared with prior art, has following beneficial effect:
1, adopt resistance divider, there is not resonance problems, performance is better than capacitive battery pressure sensor, has higher reliability;
2, vacuum transducer has been poured into a mould in the indoor increase of vacuum extinction, timely and accurately vacuum-degree monitoring is carried out to vacuum interrupter, whether its vacuum degree of Real-Time Monitoring meets safety requirements, significant to raising vacuum interrupter reliability of operation, ensure that the use safety of whole intelligent vacuum circuit breaker pole;
3, resistance divider and vacuum transducer carry out poured with epoxy resin more all in advance after silicon rubber vulcanization process, and silicon rubber intensity is high, good springiness, has good electrical insulating property, not only eliminate stress infringement, also improve integral insulation.

Embodiment
Below in conjunction with attached Example, the present invention is described in further detail.
In the description of the drawings, the intelligent vacuum circuit breaker pole 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 epoxy resin adopts pressure gelation process 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 one end wire is connected in 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 a socket position for being connected with control unit together 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; All parts encapsulatings are cast for an overall pole by epoxy package 2.
