An Outdoor Arrangement Structure of Busbar High Voltage Shunt Reactor

Abstract

The present invention provides an outdoor arrangement structure of bus high-voltage shunt reactors, including bus, grounding switches, and bus high-voltage shunt reactors, wherein the bus is connected to the bus high-voltage shunt reactors through wires through the grounding switches, and the bus high-voltage shunt reactors are arranged near There is a firewall, which is characterized in that: the position of the firewall of the bus high-voltage shunt reactor and the grounding switch are kept on the same line, and a post insulator is placed on the firewall as a transition connection between the grounding switch and the bus high-voltage shunt reactor to reduce The wire connection distance between the earthing switch and the busbar high voltage shunt reactor. The invention effectively reduces the lead wire load between the high-voltage shunt reactor of the busbar and the grounding switch, and solves the problem that the charging distance check of the road below the lead wire is difficult to satisfy.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation, and in particular relates to an outdoor arrangement structure of a high-voltage shunt reactor of a busbar. Background technique [0002] When the number of outgoing lines in the substation is large and the length is short, and it is impossible to install high-voltage shunt reactors due to capacity reasons, high-voltage shunt reactors for busbars must be installed as inductive reactive power compensation for the lines. When the substation power distribution device needs to build a bus high-voltage shunt reactor according to the grid system conditions, the conventional layout of the bus high-voltage shunt reactor is: the bus is directly connected to the bus high-voltage shunt reactor through an isolation switch, a circuit breaker, and a grounding switch. The wires used are flexible wires. Since a road is needed to transport the high-voltage shunt reactor of the busbar...

Problems solved by technology

Since a road is needed to transport the high-voltage shunt reactor of the busbar, for substations with a high altitude, the live distance verification between the flexible wires between each equipment and the road below is not easy to be satisfied with this arrangement, and at the same time, the high-voltage shunt reactor of the busbar to the grounding switch The lead load between the wires requires high strength, which poses a safety hazard during operation

Therefore, the technical problems existing in the conventional arrangement structure of the existing busbar high-voltage shunt reactor include at least: due to the long distance between the bushing of the busbar high-voltage shunt reactor and the lead wire of the grounding switch, the bushing and terminal board of the two devices require a large load. ; In substations in high-altitude areas, it is not easy to meet the calibration of the charged distance from the lead wire to the road below after altitude correction

[0003] When the power distribution device needs to increase the busbar high-voltage shunt reactor, in addition to the above-mentioned conventional layout structure, the busbar high-voltage shunt reactor structure can also be added to replace the wires between the equipment, but this technical solution occupies a large area and requires a high investment in the construction structure, which is easy to cause The overall floor area and budget of the substation exceed the standard
