Abstract
The utility model discloses a vacuum circuit breaker and an embedded pole thereof, wherein a vacuum sensor is cast in an epoxy resin insulating layer of the embedded pole, and a lead wire of a signalcable is led out from the vacuum sensor. As the vacuum sensor is arranged in the epoxy resin insulating layer outside a vacuum arc extinguishing chamber, the external electromagnetic interference andnoise interference are reduced, the accuracy of the vacuity signal is improved, and the variation of the vacuum degree of the vacuum arc extinguishing chamber can be accurately monitored.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker and pole thereof.
Background technology
At present, the pole in the high-pressure vacuum breaker comprises vacuum interrupter and epoxyresin insulator, and vacuum interrupter is flush-mounted in the epoxyresin insulator.The indoor vacuum degree of vacuum extinction must be greater than a certain vacuum degree during high-pressure vacuum breaker work, could guarantee the high-pressure vacuum breaker operate as normal when having only the indoor vacuum degree of vacuum extinction greater than a certain vacuum degree, otherwise vacuum interrupter is arc extinguishing effectively, vacuum circuit-breaker will be blasted under the serious situation, cause device damage accident and transmission line to have a power failure, cause serious economy loss.Therefore, the indoor vacuum degree of vacuum extinction is high-pressure vacuum breaker important index (parameter).The indoor vacuum degree decrease reason of vacuum extinction is a lot, can't thoroughly solve the defective that we only could discovering device when regular prerun exist, if in the prerun cycle, because the decline of the indoor vacuum degree of vacuum extinction makes effectively arc extinguishing of vacuum interrupter, causes the accident.Some producer in the arranged outside of pole have a transducer (or signal receiving device) of vacuum-degree monitoring device, the vacuum degree of vacuum interrupter in the on-line monitoring pole.Because the vacuum-degree monitoring device is installed in the outside of pole, makes its influence that is vulnerable to external electromagnetic interference, noise jamming, influences the fault-signal accuracy, can not accurately monitor the variation of vacuum level of vacuum arc-quenching chamber.
The utility model content
The purpose of this utility model provides a kind of vacuum circuit-breaker and pole thereof, disturbs to reduce external noise, and vacuum degree signal accuracy is improved, and can accurately monitor the variation of vacuum level of vacuum arc-quenching chamber.
For finishing above-mentioned purpose, the utility model has adopted a kind of vacuum circuit-breaker, comprise pole, the outdoor casting of pole vacuum extinction of this pole is formed with the epoxy resins insulation layer, also be cast with vacuum transducer in the described epoxy resins insulation layer, lead to the lead-in wire of signal cable from this vacuum transducer.
Described vacuum transducer is a metal sheet, and the signal lead of drawing on this metal sheet is the cable tail that has secondary shield.
Described metal sheet is the arc bent plate, and the arc trend of this arc bent plate is consistent with the outer surface of vacuum interrupter.
This pole one side is equipped with the vacuum degree on-line measuring device, and vacuum sensor is connected with the vacuum degree on-line measuring device by signal lead.
The secondary shield cable is outer to adopt integrated epoxyresin insulator support arm to bury underground, and support arm is supported between pole and the vacuum degree on-line measuring device.
Corresponding with above-mentioned vacuum circuit-breaker, the pole of a kind of vacuum circuit-breaker that the utility model adopts, the outdoor casting of the vacuum extinction of this pole is formed with the epoxy resins insulation layer, also be cast with vacuum sensor in the described epoxy resins insulation layer, lead to the lead-in wire of signal cable from this vacuum transducer.
Described vacuum sensor is a metal sheet, and the signal lead of drawing on this metal sheet is the cable tail that has secondary shield.
Described metal sheet is the arc bent plate, and the arc trend of this arc bent plate is consistent with the outer surface of vacuum interrupter.
The utility model pole device is because vacuum sensor is arranged in the exhausted body of the outer epoxy resin of vacuum interrupter, and the noise jamming of external environment condition has obtained isolated, has reduced the external noise interference.In addition, because vacuum sensor is arranged in the exhausted body of the outer epoxy resin of vacuum interrupter, make the distance of vacuum sensor and vacuum interrupter reduce greatly, the intensity that induced signal intensity is compared with the outside electromagnetic interference signal is enhanced, reduced the interference of external electromagnetic relatively, the fault-signal accuracy is improved, can accurately monitor the variation of vacuum level of vacuum arc-quenching chamber.
