Example Embodiment

[0019] As shown in the figure, the high-pressure fall safety quick-passing device includes a high-pressure fall safety tube 1. The upper end of the high-pressure fall safety tube 1 is provided with a spring clip lock device capable of clamping the high-pressure fall safety static contact 7. The spring clip lock The device is tightly connected with the high-pressure drop fuse 1 by screws. The spring clip lock device includes a rectangular frame housing 5 with an inner slideway. The lower frame of the insulating resin rectangular frame housing 5 is provided with a high-pressure drop fuse end through hole 9, and the rectangular frame housing 5 is provided There are an upper pressure spring copper sheet 4 and a lower pressure spring copper sheet 2. An upper spring 6 is provided between the upper pressure spring copper sheet 4 and the upper frame of the rectangular frame housing 5. The lower pressure spring copper sheet 2 and the rectangular frame housing A lower spring 8 is provide...

Abstract

The invention discloses a high-voltage dropping insurance rapid flowing device which comprises a high-voltage dropping insurance tube (1), wherein a spring clamp locking device which can clamp a high-voltage dropping insurance stationary contact (7) is arranged on the upper end portion of the high-voltage dropping insurance tube (1), and the spring clamp locking device is tightly connected with the high-voltage dropping insurance tube (1) through screws. In a power utilization peak, when insurance opening burning occurs in 10KV distribution network high-voltage dropping insurance, a high-voltage dropping fuse can not be normally closed and opened to influence normal power supply, and a repairman can not repair for long-time power failure, due to the power utilization peak or key power utilization nodes of residents at night, while the high-voltage dropping insurance rapid flowing device can achieve rapid temporary flowing, avoids large-area and long-time power failure at the power utilization peak, and therefore, reliability of power supply of a distribution network is greatly improved.

Description

technical field [0001] The invention relates to a high-voltage drop insurance, in particular to a high-voltage drop insurance quick-through installation. It is a kind of ablation of the insurance port due to the high-voltage drop insurance of the 10KV distribution network during the peak period of power consumption, which cannot be closed normally and affects the normal power supply of the power grid. At this time, it is also during the peak period of power consumption or at night. It is a fast temporary passing device used when personnel cannot repair the power for a long time. Background technique [0002] At present, the ablation damage of the interface of the distribution network drop insurance tube can only be replaced by the overall replacement of the drop insurance after a power outage. The power outage area is large and takes a long time, thus greatly reducing the power supply reliability of the distribution network operation. [0003] Therefore, it is very necessar...
