Description
Technical field
This utility model relates to a kind of four return cable terminals and draws lower device, belongs to power transmission technical field.
Background technology
Along with improving constantly of national economy, the original transmission capacity of city network can not meet electricity needs, the continuous dilatation of city network, for reducing the transmission line of electricity occupation of land in city, frequently with same tower four loop transmission line, and newly-built circuit conflicts more and more obvious with town planning, the overhead transmission line construction in city difficulty the most increasingly, the application of Voltage Cable Lines Construction will get more and more, in terms of domestic and international project example, it is all mostly four loop aerial lines to be cut-off into double loop with using again under cable termination tower, this cable form arranges complexity, floor space is big, big to urban environmental impact.
Utility model content
Purpose: in order to overcome the deficiencies in the prior art, this utility model provides a kind of four return cable terminals to draw lower device.
Technical scheme: for solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of four return cable terminals draw lower device, including: tower body, upper strata cross-arm, middle level cross-arm, lower floor's cross-arm, return wire, strain insulator string, supports insulative, cable terminal, spark gap, described return wire is set to four groups, and often group return wire includes: upper strata cross-arm wire, middle level cross-arm wire, lower floor's cross-arm wire；Four groups of upper strata cross-arm wires are set in parallel in cross-arm two ends, upper strata respectively, and four groups of middle level cross-arm wires are set in parallel in cross-arm two ends, middle level respectively, and four groups of lower floor's cross-arm wires are set in parallel in lower floor's cross-arm two ends respectively；Often group upper strata cross-arm wire separates wire jumper downlead through strain insulator string, and wire jumper downlead, after supports insulative being respectively provided with on upper strata cross-arm, middle level cross-arm, lower floor's cross-arm, introduces underground with cable terminal, spark gap after being connected；Often group middle level cross-arm wire separates wire jumper downlead through strain insulator string, and wire jumper downlead, after supports insulative being respectively provided with on middle level cross-arm, lower floor's cross-arm, introduces underground with cable terminal, spark gap after being connected；Mei Zu lower floor cross-arm wire separates wire jumper downlead through strain insulator string, introduces underground with cable terminal, spark gap after being connected；It is downlead straight down that described supports insulative is used for the cable transition of horizontal direction, and ensures the downlead electric clearance to tower body.
Preferably, described cable terminal is respectively distributed to tower body both sides, and every side cable terminal is divided into two rows, parallel arrangement.For facilitating 12 groups of cables to be evenly distributed on tower body both sides, between 12 groups of cables, occur without crossover phenomenon.
Preferably, steel tower uses conventional angle steel tower.
Beneficial effect: the four return cable terminals that this utility model provides draw lower device, steel tower uses conventional angle steel tower, and simple in construction is easy for installation, economical and practical.Upper, middle and lower cross-arm all installs some supports insulative, it is ensured that the downlead electric clearance to tower body.Without intersecting between downlead, overall structure is clean and tidy, meets distance between centers of tracks requirement between downlead.Respectively install one group of cable termination platform in steel tower both sides, 12 groups of cable downleads in four loops are converted to cable and introduce underground after being connected with cable terminal, spark gap respectively.
Accompanying drawing explanation
