Abstract
The utility model relates to a ceramic insulator capacitance integral sensor, which solves the problem that the existing core column type sensor has low pressure resistance, large local discharge quantity, easy combustion, poor reliability, small polar plate type electric capacity, weak display signal of a display device and unsatisfied actual demands. A ceramic insulated porcelain insulator is adopted, and the axial cross section of the center of the inner cavity thereof is formed into two continuous equidistant cylinder hollow bodies; the equidistant position is coated with a metallic film. Electrodes, a spring, an upper and a lower seats, fillers and concretes are installed in the inner cavity of the insulated porcelain bottle, wherein, the spring is fastened by a screw and is used as one electrode of the capacitor in the inner bore of the upper seat.
Description
The utility model belongs to sensor, particularly a kind ofly is connected the porcelain insulator electric capacity integrated transducer that being used to of using shows that the whether charged signal of high-voltage charged body transmits with display device.
Existing sensors adopts stem stem formula or polar-plate-type, all has the transmission high voltage functionality, and the double as pillar insulator of determining uses (seeing CN90202251.2, CN88221154.4) again.The stem stem formula is to adopt support insulator, stem stem electric capacity and epoxy resin secondary to water jar to form, though signal is strong, because the epoxy resin organic material, unavoidably in the process of watering produce bubble and slit, thereby cause withstand voltage lowly, partial discharge quantity is big, inflammable, life-span is short, and poor reliability is dangerous.
Polar-plate-type is then opposite, and electric capacity is little, and signal is little, thereby a little less than the shows signal of display device, does not satisfy actual needs.
The purpose of this utility model is to solve above-mentioned existing problem, provides a kind of electric capacity big, the porcelain insulator electric capacity integrated transducer that signal is strong.
The utility model is achieved in that it has a porcelain insulator, and the inner chamber top of porcelain insulator has endoporus, and its endoporus depths is cylindrical in the central axis position, is annular at endoporus depths perisporium; The bottom of porcelain insulator has endoporus, and endoporus depths diameter reduction is a ring groove, makes the porcelain insulator inner chamber be formed with two continuous equidistant hollow cylindrical bodies.On U type A, B, C, D and the plane E of formed two continuous equidistant hollow cylindrical bodies, layer of metal film is arranged; Installing electrodes in the cylindricality endoporus of the inner chamber of porcelain insulator, the electrode lower end contacts with metal film, electrode upper end mounting spring, the top endoporus of porcelain insulator is equipped with the seat of honour, spring is filled out envelope with inorganic material or organic material after the leading-out end line in formed two the continuously equidistant hollow cylindrical bodies of porcelain vase inner chamber in the endoporus at the seat of honour.Between the seat of honour and porcelain insulator, be cast with concrete, in the lumen orifice at the seat of honour, be equipped with the screw in compression spring, as a utmost point of electric capacity by screw thread; The electric capacity pole piece is installed at E face metal film place at the inner chamber of porcelain insulator, and draws outer another utmost point as electric capacity of porcelain insulator by lead.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of porcelain insulator of the present utility model;
Fig. 3 is the partial enlarged drawing at Fig. 2 F place;
Fig. 4 is embodiment of the present utility model;
Describe and provide embodiment in detail below in conjunction with accompanying drawing;
As shown in the figure, the utlity model has one and once fire the porcelain insulator 3 that the middle part that forms has inner chamber with pottery, the inner chamber top of porcelain insulator 3 is endoporus, have the groove (see figure 3) on its inner hole wall, the endoporus depths is cylindrical in the central axis position of porcelain insulator 3, is ring groove in endoporus perisporium depths; The bottom of porcelain insulator 3 has endoporus, is ring groove after the diameter reduction of endoporus depths, makes porcelain insulator lumen centers axial cross section be formed with two continuous equidistant hollow cylindrical bodies.Scribble layer of metal film as pole-face on U type A, B, C, D and the plane E of formed two continuous equidistant hollow cylindrical bodies, thereby the pole-face that has strengthened electric capacity is long-pending, this metal film can be used silverskin; Installing electrodes 6 in the cylindrical bore of the inner chamber of porcelain insulator, electrode 6 lower ends contact with B face metal film, electrode 6 upper end mounting spring 4, the top endoporus of porcelain insulator 3 is equipped with the seat of honour 1, spring 4 is filled out envelope at formed two the continuously equidistant hollow cylindrical bodies of porcelain insulator inner chamber with inorganic material or organic material 5 in the endoporus at the seat of honour 1; In 1 endoporus of the seat of honour, be equipped with screw 10 holddown springs 4 and as the utmost point of electric capacity, at the E face metal film place of the inner chamber of porcelain insulator 3 electric capacity pole piece 7 be installed and drawn outside the porcelain insulator 3 another utmost point by lead as electric capacity by screw thread.In the endoporus of the bottom of porcelain insulator 3, install following 9, and be equipped with packing ring 2, packing ring 8 at porcelain insulator 3 and the seat of honour 1, between following 9.Place, envelope crack between porcelain insulator 3 and the seat of honour 1 and following is cast with concrete.
During use, the exit by screw 10 and electrode 7 is connected in the high-tension line, sees Fig. 4, and 11 is porcelain insulator electric capacity integrated transducer, and 12 for having the display of a, b, c, d connection terminal.Can the utility model is rack-mount by the screw on following 9 with screw; Show by display whether high-tension line is charged,, make the display lamp of display very eye-catching because the utility model capacity is big.
