Description

Technical Field

[0001] The invention belongs to the field of power transmission and transformation, and in particular relates to an outgoing line arrangement structure of a 330kV HGIS power distribution device. Background Art

[0002] With the rapid development of power grid construction, the scale of ultra-high voltage substation projects is getting larger and larger. The problem of large land occupation by conventional distribution device layout is becoming more and more prominent. The land reserve resources are seriously insufficient, the site acquisition and demolition costs are increasing, and the land acquisition costs are showing a clear upward trend. The selection of substation sites is becoming more and more difficult. Improving the utilization rate of land resources is a topic that power grid construction must face. As far as the design of high-voltage distribution devices in substations is concerned, optimizing the outgoing line layout of distribution devices, when designing the distribution devices, outgoing line frames and line corridors of outgoing line loops, comprehensively considering the three-dimensional compact layout, reducing the outgoing line space, maximizing land conservation, and improving land utilization can provide technical support for the construction of subsequent substation projects, which is of great significance. Summary of the invention

[0003] The object of the present invention is to provide a 330kV HGIS distribution device outgoing line arrangement structure to address the above-mentioned problems in the prior art, which can reduce the area occupied by outgoing line equipment, improve land utilization, and save investment.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a 330kV HGIS power distribution device outgoing line arrangement structure, a conventional outgoing line is outgoing from the high-span II bus near the II bus side bushing; a conventional outgoing line voltage transformer and a conventional outgoing line lightning arrester are arranged in the interval along the lateral outgoing direction of a circuit; a lateral outgoing line jumps from the bushing near the I bus side to the interval, and the high-span I bus is outgoing laterally; a lateral outgoing line voltage transformer and a lateral outgoing line lightning arrester are arranged in the interval between a lateral outgoing line and a conventional outgoing line.

[0005] A conventional outgoing line jumps to the interval through the bushing near the II busbar side of the HGIS circuit breaker, and is connected through the II busbar upper side outgoing line transition jumper.

[0006] A conventional outgoing line is connected to a conventional outgoing line voltage transformer and a conventional outgoing line lightning arrester through a lead line from the II mother upper side outgoing line transition jumper.

[0007] A lateral outgoing line passes through the HGIS circuit breaker and jumps to the upper bushing near the I bus side to connect to the I bus upper side outgoing line transition jumper in the bay, and is connected to the I bus upper side outgoing line high transition jumper in the bay via the I bus upper side outgoing line vertical transition lead.

[0008] The height of the high transition jumper of the upper side outlet line of the I mother is higher than the transition jumper of the upper side outlet line of the I mother.

[0009] A lateral outgoing line is connected to a lateral outgoing line voltage transformer and a lateral outgoing line lightning arrester through a lead line from the I bus upper side outgoing line transition jumper.

[0010] Compared with the prior art, the present invention utilizes the space in the outgoing line interval to arrange the voltage transformer and lightning arrester of the lateral outgoing line in the interval, which is 90 degrees to the lateral outgoing line and 180 degrees to the forward outgoing line direction. The equipment leads are arranged vertically in space, and the upper, middle and lower transition leads in the interval are staggered up and down, which solves the difficulty of arranging the upper equipment leads. At the same time, the two outgoing line equipment arrangements share a spacing width, which can effectively reduce the area occupied by the lateral outgoing line equipment, save the area occupied by the substation, and save civil engineering investment.
