Abstract
In order to solve technical problems, the utility model adopts the technical proposal that a lightning-protection device for a transformer is made up of a transformer, a primary conduct pole, a lightning arrester, a fixing bracket, a high tension lead and an earth lead, wherein the fixing bracket for the lightning arrester is arranged on the side edge of the transformer; the lower end of the lightning arrester is fixed on the fixing bracket; the high tension lead is fixed at the upper end of the lightning arrester and connected to the primary conduct pole through a connecting plate; and the fixing bracket is communicated with the earth lead through the casing of the transformer. The utility model has the beneficial effects as follows: the usage amount of erected cross arms is reduced, the used length of the high-tension line is shortened, the resource is saved, and large amounts of costs are saved.
Description
Affiliated technical field
The utility model relates to a kind of emergency protective device, especially transformer lightning protection device.
Background technology
When the actual installation lightning arrester, the high-pressure side lightning arrester is installed between high-tension fuse and the transformer more, and as far as possible near transformer, in the 8.0.5 bar regulation of " overhead distribution designing technique rules " SDJ206-87 of People's Republic of China's hydraulic and electric engineering ministerial standard: the distribution transformer lightning protection device should be tried one's best and be installed near transformer.In other lightning protection rules, also only require lightning arrester near more good more, generally should not surpass 5m apart from protected equipment.In addition, in the installation of high pressure hack lever a lot of dimensional requirements are arranged.Mounting points as lightning arrester should be greater than 0.7m apart from fuse, the minimum perpendicular distance of joint using between high pressure and the high pressure between the circuit cross-arm is 0.80m, corner or branch line are as being single loop line, then the branch line cross-arm is 0.6m apart from the backbone cross-arm, as be double loop, then the branch line cross-arm is 0.45m apart from last row's backbone cross-arm, is 0.6m apart from arranging the backbone cross-arm down.This backbone cross-arm and branch line cross-arm that just requires to set up all will have bigger length, and this just need spend very high expense on cross-arm, has also wasted resource simultaneously.
Summary of the invention
The utility model provides a kind of transformer lightning protection device, has solved waste resource and cost problem of higher in the existing lightning arrester installation.
The technical scheme that its technical problem that solves the utility model adopts is: transformer lightning protection device; constitute by transformer, primary conductive bar, lightning arrester, fixed support, high-voltage connection and earth connection; the side of transformer is along the fixed support that is provided with lightning arrester, and the lower end of lightning arrester is fixed on the fixed support.High-voltage connection is fixed on the lightning arrester upper end and is connected on the primary conductive bar by connecting plate.Fixed support is by the housing and the earth connection UNICOM of transformer.
The beneficial effect of generation of the present utility model is, reduced the use amount of setting up cross-arm, shortened the use length of high-voltage line, saved resource, and saved a large amount of expenses.
Description of drawings
Accompanying drawing is the structural representation of the utility model transformer lightning protection device.
Embodiment
Transformer lightning protection device; constitute by transformer 1, primary conductive bar 2, lightning arrester 3, fixed support 4, high-voltage connection 5, earth connection 6 and connecting plate 7; the side of transformer 1 is along the fixed support 4 that is provided with lightning arrester 3, and the lower end of lightning arrester 3 is fixed on the fixed support 4.High-voltage connection 5 is fixed on lightning arrester 3 upper ends and is connected on the primary conductive bar 2 by connecting plate 7.Fixed support 4 is by the housing and earth connection 6 UNICOMs of transformer 1.This structure that the utility model adopts, directly be fixed on the transformer lightning arrester, the use that can save the lightning arrester load on the basis of prototype structure can be shortened the length of the support load of fuse cross-arm simultaneously, supports load to foreshorten to 1.0 meters by original 1.5 meters.Support load for two 0.5 meter that shortens, be welded as 1.0 meters new support loads.1.2 meters lightning arrester loads that are cancelled and 1.0 meters loads that newly are connected into have been formed the support of new transformer platform drop switch and have been carried on a shoulder pole.That is to say, become four present loads, raise the efficiency 75%, and also shortened the use amount of lead-in wire by three original loads.The expense of so not only having saved has also been saved resource.
