Abstract
The utility model discloses a vacuum switch tube with a vacuum transducer comprising a vacuum switch tube body, and a transducer arranged at the still end of the vacuum switch tube body; a porcelain casing is provided on the transducer, and the external wall of the porcelain casing is uniformly distributed and is opened with concave grooves. An anode sealing cap and a cathode sealing cylinder are respectively welded on the bottom face and the top face of the porcelain casing. The anode sealing cap is welded on the vacuum switch tube body; an anode plate is arranged inside the porcelain casing and an invert U shaped cathode plate is arranged inside the cathode sealing cylinder; two permanent magnets are fixedly connected with the two sides opposite to the cathode sealing cylinder and with the position corresponding to a through hole. The arrangement of a cathode plate into an invert U shape facilitates easy installations, and the plural bar shaped grooves arranged on the external wall of the porcelain casing greatly increase the insulation capability of the vacuum switch tube. In addition, vacuum pressure signals of a vacuum switch tube are transmitted out from the anode sealing cap of the vacuum transducer before further being transmitted to an online monitoring apparatus, which helps realize the online monitoring of the pressure inside the vacuum switch tube.
Description
Technical field
The utility model relates to a kind of arc control device, relates in particular to a kind of vacuum interrupter with vacuum transducer.
Background technology
Itself is not with vacuum transducer existing vacuum interrupter, in use, vacuum pressure situation of change in the body can't be known, monitor very inconvenient, if inner vacuum pressure raises, vacuum interrupter will lose connecting-disconnecting function, even cause accident of power supply, produce immeasurable loss, for this reason, someone has designed a kind of vacuum switch tube that has the gamut transducer of the patent No. 99224560.5, but this vacuum switch tube is very inconvenient when making, and especially minus plate is not easy to install very much, and when circuit turn-on, electric current is short along the shell creepage distance of vacuum interrupter, and insulation level is low.
The utility model content
The purpose of this utility model is to provide a kind of vacuum interrupter with vacuum transducer, can effectively solve existing vacuum interrupter and be difficult for monitoring, is difficult for making and the short problem of creepage distance.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of vacuum interrupter with vacuum transducer, comprise the vacuum interrupter body, at the quiet end of vacuum interrupter body one vacuum transducer is installed, this vacuum transducer is provided with the porcelain shell outward, the outer wall of described porcelain shell evenly has several around the porcelain shell groove in one week, porcelain shell inwall has the positive plate location hole and two the minus plate location holes that are symmetrically distributed with the center that are positioned at the center, porcelain shell bottom surface and end face soldering respectively have an anode seal cap and negative electrode sealing drum, the soldering of described negative electrode sealing drum is on the vacuum interrupter body, be provided with the positive plate of a band through hole in porcelain shell positive plate position of positioning hole, this positive plate one end soldering is fixed on the anode seal cap, the other end stretches in the negative electrode sealing drum, and described through hole is positioned at the negative electrode sealing drum, an inverted U-shaped minus plate is installed in the negative electrode sealing drum, two vertical sections of described minus plate are parallel with positive plate, and in the minus plate location hole of the corresponding insertion in its two ends porcelain shell, have a circular hole at the end face of minus plate over against the air vent hole position of the quiet end of vacuum interrupter body, relative both sides of the outer wall of this negative electrode sealing drum and through hole corresponding position also are fixedly connected with a permanent magnet respectively.
Compared with prior art, advantage of the present utility model is: minus plate is inverted U-shaped, convenient when mounted, porcelain shell outer wall evenly has several around the porcelain shell groove in one week, can effectively increase creepage distance, improve insulation effect, in the vacuum interrupter use, quiet end conducting surface passes to high pressure, this vacuum transducer is started working, on-Line Monitor Device is drawn and offered to the vacuum pressure signal by the anode seal cap place of vacuum transducer in the vacuum interrupter pipe, just can realize the on-line monitoring of vacuum interrupter intraductal pressure.
