Heterostatic live line connection line device for high-voltage power distribution network

Abstract

The invention relates to a heterostatic live line connection line device for a high-voltage power distribution network. The heterostatic live line connection line device for the high-voltage power distribution network comprises a wire clamp and an additional component, wherein the wire clamp comprises a fixed clamping block 1, a movable clamping block 3, a back clamping block 4, an auxiliary support sleeve 9, a guide sleeve 6, a guide rotating sleeve 7, a telescopic tensioning mechanism 5 and a locking bolt 10; the auxiliary support sleeve 9 is arranged at the lower end of the fixed clamping block 1; the guide sleeve 6 sleeves the upper end of the auxiliary support sleeve 9; the telescopic tensioning mechanism 5 is located in the movable clamping block 3 and is connected with the upper end of the guide sleeve 6; the locking bolt 10 is inserted into the lower end of the guide rotating shaft 7; the additional component comprises an upper support sleeve 11, a lower support sleeve 13, an insulating rod sleeve 16, an insulating rod 17 and a locking sleeve 12; the upper support sleeve 11 sleeves the auxiliary support sleeve 9; and the insulating rod 17 is inserted into the insulating rod sleeve. The heterostatic live line connection line device overcomes the defect that connection can only be carried out in a power failure, achieves T connection of a newly built or broken power line in the absence of a load and the power failure, and has the advantages of being concise in structure, convenient to operate, good in contact effect, stable in snapping effect and the like.

Description

technical field [0001] The invention relates to a wire connecting fitting in an electric power system, in particular to a device for bonding live wires with different potential charges in a high-voltage power distribution network. Background technique [0002] In a power system in a high-voltage state, if a new line or a new user transformer is to be connected to the power network and put into operation, the live wire device used in the current power distribution line is the copper wire device disclosed in the Chinese patent with the authorized announcement number CN203026655U. Aluminum parallel ditch clamp, it is a device used in 35kV and 10kV distribution network line lapping and T connection. At present, new 10kV lines and new users need to use the parallel ditch clamp T connection to fire when the power is cut off. However, power outages and fires need to be applied in advance according to the requirements of the power industry. The interval between approval and implemen...
