Description
Technical field
The utility model relates to lightning arrester and makes field, particularly a kind of three-phase pot type gapless metal-oxide lighting arrester of 126kV electric pressure.
Background technology
Fully closed combined electric unit (GIS) with its floor space little (have only conventional equipment take up an area of 15%～35%), element all seal, be not subjected to environmental interference, reliability height, advantage such as the time between overhauls(TBO) is long, maintenance workload is few, installation is rapid, operating cost is low, in bulk of worldwide electricity industry, obtain application more and more widely.
Generally need carry out withstand voltage test after the GIS installation, and lightning arrester then needs lightning arrester is left from the GIS device interrupt because its particularity can not be carried out withstand voltage test together with switchgear, assemble again after finish test.Usually the way that disconnects lightning arrester has only 2 kinds: one for directly disassembling lightning arrester, and the 2nd, at the adjacent air chamber of lightning arrester an isolation switch is set.First kind of way is cumbersome, needs dismounting lightning arrester back and forth, wastes time and energy.And the isolation switch that the adjacent air chamber of lightning arrester is provided with in the second method only uses once when installation and overhaul, is unfavorable for the development trend of switchgear miniaturization, has also increased the cost of GIS switchgear.
The utility model content
The purpose of this utility model is to provide a kind of three-phase pot type lightning arrester, this lightning arrester can cut-off operation in the outside realization of lightning arrester, and can under the situation of not dismantling lightning arrester, cut-off operation to lightning arrester, solved in the fully closed combined electric unit problem of withstand voltage about lightning arrester.
In order to achieve the above object, the utility model gives by the following technical solutions and realizing.
A kind of three-phase pot type lightning arrester that has manual partition apparatus, it comprises tank body, and be arranged on three-phase core body in the tank body, it is characterized in that, described lightning arrester tank body offers top exit and side exit, described top exit is fixed with the three-phase disc insulator, and three-phase disc insulator lower end links to each other by the partition apparatus that is connected on Mume flower contact and the three-phase core body, and three-phase disc insulator upper end top exit end links to each other with the GIS switch; Described side exit is fixed with the partition apparatus operating mechanism, and this operating mechanism cut-offs by output shaft and partition apparatus attended operation lightning arrester.
Further improvement of the utility model and characteristics are:
The upper end of described three-phase core body is provided with partition apparatus, and the screening can of this partition apparatus is connected with the three-phase core body by bolt.
Described operating mechanism is connected with three output shafts.
This lightning arrester is a three-phase jar structure altogether, aluminum enclosure, and have pressure relief device, partition apparatus and monitor.Product is a main element with the zinc oxide resistance sheet with good voltage-current characteristic and big through-current capability, and core body adopts three post parallel-connection structures, is installed in and is filled with SF
6In the tank body of gas.
This three-phase pot type lightning arrester, after the assembling of GIS combined electrical apparatus is finished, when carrying out withstand voltage test, operate the operating mechanism of lightning arrester outside earlier, make three-phase conductor and three-phase core body throw off, an isolation switch or dismounting lightning arrester need be set at the adjacent air chamber of lightning arrester.Its compact conformation can make taking up room of whole fully closed combined electric unit reduce, and the seal member minimizing, can improve equipment dependability, fail safe.
Description of drawings
Fig. 1 is the structural representation of a kind of three-phase pot type lightning arrester with manual partition apparatus of the utility model.
Among the figure: 1, disc insulator; 2, Mume flower contact; 3, flexible conducting rod; 4 partition apparatus; 5, tank body; 6, three-phase core body; 7, output shaft; 8, operating mechanism.
Embodiment
With reference to Fig. 1, mainly comprise disc insulator 1, Mume flower contact 2, flexible conducting rod 3, partition apparatus 4, tank body 5, three-phase core body 6, output shaft 7, operating mechanism 8 with the three-phase pot type lightning arrester of manual partition apparatus.Wherein, three-phase core body 6, partition apparatus 4 are arranged in the tank body 5, on tank body 5, offer two outlets, top exit top is propped up mouth and is used to install disc insulator 1, this three-phase disc insulator 1 is connected with partition apparatus 4 by Mume flower contact 2, three-phase disc insulator 1 top exit end links to each other with the GIS switch, and its effect is to dock with the GIS switchgear; The sidepiece outlet is used for fitting operation mechanism 8, and operating mechanism 8 is connected with partition apparatus 4 by output shaft 7, and its effect is the conducting between operation partition apparatus realization lightning arrester three-phase core body 6 and the disc insulator 1 and cut-offs.
And the upper end of three-phase core body 6 (high-pressure side) is provided with partition apparatus 4, and the screening can of described partition apparatus 4 is connected by the high-pressure side of bolt with three-phase core body 6.
The partition apparatus 4 inner gear tops of adopting connect rack structure, gear, tooth bar and flexible conducting rod 3 are installed in the screen shell of partition apparatus 4, connect three output shafts 7 that link to each other with operating mechanism 8 along the gear axis level, along the vertical conducting rod 3 that stretches that connects of tooth bar, the bottom of partition apparatus 4 is fixed by bolts on the three-phase core body 6, reliably connects between them.When operating mechanism 8 forward rotation output shafts 7, the gear driven tooth bar moves upward, and flexible conducting rod 3 moves upward, and inserts in the top Mume flower contact 2 the lightning arrester conducting.When backward rotation output shaft 7, the gear driven tooth bar moves downward, and flexible conducting rod 3 moves downward, and throws off from Mume flower contact 2, and lightning arrester disconnects.
The use of the lightning arrester that present embodiment relates to can be shortened the withstand voltage test cycle of GIS equipment, and the structure that back GIS electric equipment is installed is compact more, helps making GIS miniaturization and intelligent development.
