Problems solved by technology

However, due to the existence of various unpredictable factors such as the ever-changing operation status of the power grid and the unqualified quality of fuses, any preventive method cannot fundamentally eliminate the occurrence of accidents.
The analysis of multiple explosion accidents of 10kV and 35kV distribution network bus voltage transformer cabinets shows that the typical accident process is: the fuse is too long in the pre-arcing tim...

Abstract

The invention discloses a portable fuse performance auxiliary test rack, comprising a pedestal, handles, supporting insulators, axial clamping conducting bars, radial clamping conducting bars and test line banks. Left and right sides of the pedestal are provided with the handles; the two supporting insulators are arranged on the pedestal; and the axial clamping conducting bars, the radial clamping conducting bars and the test line banks are mounted on the supporting insulators, wherein the axial clamping conducting bases and the radial clamping conducting bars are used for mounting and clamping a fuse to be tested, and the test line banks are used for being connected with peripheral test equipment. The portable fuse performance auxiliary test rack provided by the invention is reasonable in structure and convenient to use.

Description

technical field [0001] The invention relates to a portable fuse performance auxiliary test stand for a high-voltage switch cabinet. Background technique [0002] High-voltage switchgear refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. High-voltage switchgear is used as electrical products with a voltage level of 3.6kV~550kV, and high-voltage isolating switches And grounding switch, high-voltage load switch, high-voltage automatic recloser and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear and other major categories. [0003] The high-voltage switchgear has functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and bus connection. It is mainly applicable to various fields such as power plants, substations, petrochemicals, metallurgical steel rolling, light in...
