Detailed Description
For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings and examples. It is to be understood that the examples are illustrative of the invention only and are not limiting.
Example 1
As shown in fig. 1 to 6, the present embodiment provides a fully insulated, fully sealed, inflatable ring main unit switch device with an electrical breaker, which includes a ring main unit 110, an air chamber 610 is disposed in the ring main unit 110, a pressure relief mechanism 620 is disposed on the air chamber 610, the pressure relief mechanism 620 includes a pressure relief hole 310 disposed at an upper end portion of the ring main unit 110, a pressure relief channel 320 matched with the pressure relief hole 310 is disposed at the upper end portion of the ring main unit 110, a cover plate 330 for sealing the pressure relief channel 320 is disposed at the upper end portion of the pressure relief channel 320, a cylindrical mounting base 340 is disposed on an end surface of the cover plate 330 adjacent to the pressure relief channel 320, an end portion of the mounting base 340 extends into the pressure relief channel 320, and the mounting base 340 is in clearance fit with; a guide rod mounting bracket 350 is arranged in the middle of the pressure relief channel 320, the guide rod mounting bracket 350 comprises a mounting plate 410, a guide hole 420 is formed in the center of the mounting plate 410, a slidable guide rod 360 is arranged in the guide hole 420, and a plurality of connecting blocks 430 fixedly connected with the inner wall of the pressure relief channel 320 are arranged on the mounting plate 410; a screw hole 510 is formed in the center of the bottom end surface of the mounting base 340, and a first thread 520 matched with the screw hole 510 is formed at the upper end of the guide rod 360; a base 370 is arranged at the bottom end of the guide rod 360, a spring 380 used for tightly abutting the cover plate 330 on the pressure relief channel 320 is sleeved on the guide rod 360, one end of the spring 380 abuts on the mounting plate 410, and the other end of the spring 380 abuts on the base 370.
When the fully insulated and fully sealed inflatable ring main unit switch device with the breaker in this embodiment is in use, when the air pressure in the ring main unit 110 is high, the high-pressure gas will jack up the cover plate 330 and the mounting base 340, so that the high-pressure gas is discharged from the upper end of the pressure relief channel 320, and when the air pressure in the ring main unit 110 drops, the cover plate 330 abuts against the upper side of the pressure relief channel 320 under the pulling force of the spring 380, so that the sealing state in the ring main unit 110 is restored, and thus, the automatic pressure relief and explosion prevention are realized. When the fully insulated and fully sealed inflatable ring network switch device with the breaker in this embodiment is installed, the cover plate 330 is placed above the pressure relief channel 320, then the spring 380 is installed at the bottom end of the guide rod 360, and finally the end of the guide rod 360 penetrates through the guide rod installation bracket 350 and is fixed on the installation base 340 to complete the installation of the guide rod 360.
