The utility model content:
The purpose of this utility model is to provide and can satisfies actual requirement of engineering, a kind of line steel tower that adopts in power distribution equipment, and the turnover line is the series compensation device new design structure of vertical arrangement.
For achieving the above object, the utility model takes following technical pattern to be achieved:
A kind of employing line steel tower series compensation system, described series compensation system comprises series compensation device body, line steel tower, lead, insulator string and open type equipment; The turnover line of described series compensation system all adopts line steel tower, respectively the series compensation device body is arranged in circuit both sides or a side.
Described series compensation device body comprises series capacitor, lightning arrester, discharging gap, bypass breaker, auxiliary circuit breaker, damping element, auxiliary equipment, insulated platform.
Described open type equipment comprises lightning arrester, isolating switch and voltage transformer.
Other lightning arrester, isolating switch, the voltage transformer of being provided with of described series compensation device body.
Described line steel tower is common-tower double-return or single loop line tower, and the turnover line is vertical arrangement.
Described insulated platform is one or more.
Adopt line steel tower in the series compensation of the present utility model system, the turnover line is the series compensation device new design structure of vertical arrangement, described series compensation device has adopted line steel tower to replace conventional door type framework, each phase conductor of turnover line is vertical arrangement, corresponding to common-tower double-return and single loop tower, respectively series compensation device is arranged in circuit both sides or a side.
The utility model advantage is:
1, adopt line steel tower, pass in and out line all by after the vertical direction arrangement, both be beneficial to the rationalization partition of string benefit device on the different circuits, significantly compression strings recruits the occupation of land of electric installation zone again, and the reduction land expropriation cost economizes the land resource;
2, avoided each phase series compensation platform interlaced arrangement of installing on the different circuits, for between each circuit, normal operation maintenance, the maintenance between mending of circuit and string created advantage, every loop line road string is mended or the repair and maintenance of circuit does not all have influence on the normal operation on this loop line road or another loop line road;
3, string is mended the outside that device is arranged in circuit, has reduced loss of outage when string is mended turnaround of unit, has saved construction investment.
4, owing to adopted and identical tower and the conductor arrangement mode of circuit specialty, can cooperate more in phase, reduce the project of transmitting and converting electricity gross investment with circuit.
5, according to transformer station's (or string is mended the station) actual conditions, each building is arranged in turnover line lead below, not newly-increased the occupation of land, further economize the land resource.
6, line steel tower is only established each 1 in inlet wire and outlet tower, is used for A and is connected mutually and under the C phase conductor draws, and B phase conductor junction has adopted two strain insulator strings to be connected in series in the middle of the circuit, establishes the circuit tower no longer separately, has saved investment.
7, this scheme framework steel using amount is few, saves construction investment;
8, this scheme wiring is succinct, saves the investment of gold utensil and lead.
