specific Embodiment 1

[0073] like figure 1 figure 2 , image 3 and Figure 4 As shown, the integrated VFTO measuring bus includes a bus barrel 1 and a VFTO measuring device 2 integrated on the bus barrel 1. The two ends of the bus barrel 1 are respectively provided with barrel flanges 17, so as to correspond to the corresponding GIS / GIL bus connection. The busbar barrel 1 is provided with a three-pillar insulator 4 , and the three pillars of the three-pillar insulator 4 are respectively in contact with the barrel wall of the busbar barrel 1 for fixing the conductive rod 5 penetrated in the busbar barrel 1 . A cylindrical particle trap 3 is also provided in the busbar barrel 1 . The side of the busbar barrel 1 is provided with a pull-out port, and the pull-out port is fixedly fitted with a flange matching barrel 18 extending along the radial direction of the busbar barrel 1. The VFTO measuring device 2 is connected to the flange matching barrel 18 through the connecting flange 6 on it. The in...

Embodiment 2

[0082] The difference between this embodiment and the above-mentioned Embodiment 1 is that in this embodiment, a sealing sleeve is set on the outside of the entire VFTO measuring device, and the sensor is located in the sealing sleeve. To realize the integration of VFTO measuring device and busbar barrel.

Embodiment 3

[0084] The difference between this embodiment and the above-mentioned Embodiment 1 is that in this embodiment, no support seat and transition flange are provided, and the shielding ring is directly connected to the connecting flange through bolts and nuts, but it must be ensured that the shielding ring is connected to the conductive rod and the bus bar. The distance between the cylinders meets the requirements.

Abstract

The invention relates to an integrated VFTO measuring bus and a bus cylinder thereof. The VFTO measuring bus comprises a bus cylinder, a conducting rod arranged in the bus cylinder and a supporting insulator used for supporting the conducting rod. A VFTO measuring device is integrated on the bus cylinder, the bus cylinder is used for being in butt joint with a GIS/GIL bus, a supporting insulator is arranged in the bus cylinder, and the supporting insulator is used for supporting the conducting rod; and the VFTO measuring device is used for measuring the VFTO between the bus cylinder and the conducting rod. The integrated VFTO bus adopts an integrated structure and can be directly butted with a corresponding GIS/GIL bus during installation and can be directly connected with corresponding measurement equipment for measurement during measurement and is easy to operate and convenient to measure.

Description

technical field [0001] The invention relates to the field of power transmission and transformation equipment, in particular to an integrated VFTO measurement bus bar and a bus bar barrel. Background technique [0002] The isolation switch, grounding switch and circuit breaker in GIS equipment will generate very fast transient overvoltage with high amplitude, steepness and frequency during operation. Due to the slow operation speed of the isolating switch and no arc extinguishing device, there will be multiple pre-breakdowns during its opening and closing operations, and each pre-breakdown will be accompanied by oscillating electromagnetic waves. Electromagnetic waves have various properties of waves and are transmitted In the process, there will be a phenomenon of refraction and reflection, which will cause the superposition of electromagnetic waves and cause overvoltage. Therefore, the main source of VFTO can be considered to be caused by the operation of the isolation swit...
