Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, dry-type transformer bottom shielding of bushing ejector of the present utility model, connects plug 2, sleeve pipe mounting flange 3, ground connection holddown spring the 4, first sealing ring 5, tap mounting seat the 6, second sealing ring 7, tap ground connection helmet 8 including end shield 1, end shield.
End shield of the present utility model 1 and sleeve pipe mounting flange 3 insulate interlayer, next via coaxial with the end shield installation internal thread hole that sleeve pipe mounting flange 3 is arranged of pre-subdrilling, this hole internal diameter connects plug 2 lower end external diameter slightly larger than end shield, on the premise of ensureing assembling operability, improve device shock resistance as far as possible.Ground connection holddown spring 4 one end is connected the installation step end face of plug 2 and is in close contact with end shield, and one end is in close contact with tap mounting seat 6 reducing end face.End shield connect plug 2 at installation step be one section with ground connection holddown spring 4 internal diameter cylinder closely, to ensure that ground connection holddown spring 4, end shield connect the axiality of plug 2 and tap mounting seat 6, improve and assemble operability.End shield connects plug 2 bottom and end shield 1 reliable contacts, and end shield connects plug 2 upper end through the special-shaped anti-rotating hole at tap mounting seat 6 axle center and tap ground connection helmet 8 reliable contacts.End shield connects at plug 2 and 8 contact positions of tap ground connection helmet, increases outside passive exposure formula arcuately lantern body spring leaf, the reliable contacts of dual both guarantees, improves the Earthing Reliability of end shield ejector.The end shield that tap mounting seat 6 and sleeve pipe mounting flange 3 are arranged is installed internal thread hole and is fastenedly connected；Meanwhile, tap mounting seat 6 top is provided with external screw thread, coaxially engages with the internal thread hole of tap ground connection helmet 8.Tap mounting seat 6 and axially arranged first sealing ring 5 of sleeve pipe mounting flange 3 contact surface, tap mounting seat 6 contacts end face with head ground connection helmet 8 and arranges the second sealing ring 7, thus improve the sealing of end shield ejector, preventing end shield ejector from working due to long-term outdoor, end shield ejector internal structure corrosion failure and electric property that the intrusion of wet gas or other erosions causes decline.
In installation process, first the first sealing ring 5 is placed in the cannelure of tap mounting seat 6 lower end；Then ground connection holddown spring 4 is connected plug 2 upper end through end shield and be placed on the installation step end of end shield connection plug 2；Then end shield is connected plug 2 upper end and penetrates in abnormity anti-rotating hole from tap mounting seat 6 bottom circular endoporus until ground connection holddown spring 4 and tap mounting seat 6 reducing end contact；(this step needs observation end shield to be connected whether the reticle at plug 2 axial direction occurs in design tram after completing with sleeve pipe mounting flange 3 end contact in then tap mounting seat 6 screws in the end shield installation internal thread hole that sleeve pipe mounting flange 3 is arranged until tap mounting seat 6 lower surface, as position is overproof, there is the risk of loose contact)；Then the second sealing ring 7 is placed in the cannelure of tap mounting seat 6 upper end；Finally screw at tap ground connection helmet 8 to tap mounting seat 6 threaded upper ends, until tap ground connection helmet 8 lower surface contacts with tap mounting seat 6 upper surface.
