Abstract
The utility model relates to an anti-thunder power distributing transformer. Under the precondition the unchangeableness of the design parameters and the technical performance of the normal power transformer, the power transformer is additionally provided with a set of lightning protecting device; the device is formed by that three lightning arresters are is plugged on the middle position of the upper cover of the casing of the transformer; the lower end of the lightning arrester is fixed in the fuel tank to be dipped into oil; the upper end of the lightning arrester is respectively connected with the binding post of a high-voltage power supply via an over line. The transformer has reliable and sensitive lightning performance, extending the service life and the repair cycle of the lightning protecting device, and reducing the installing and repair expense.
Description
The present invention relates to a kind of power transformer, i.e. the lightning protection power distribution transformer.
Add three groups of high-voltage line tipping lightning arresters when power transformer of the prior art is installed on transformer platform, complexity is installed, mounting cost is higher, and maintenance is convenient inadequately, and lightning-arrest performance reliability is poor, needs necessary maintenance in every year once.
The objective of the invention is to avoid above-mentioned weak point of the prior art and a kind of lightning protection power distribution transformer is provided, transformer self is equipped with lightning arrester, and it is easier that transformer is installed, lightning-arrest dependable performance, not fragile, the time between overhauls(TBO) is long, reduces installation, recondition expense.
Purpose of the present invention can reach by following measure: a kind of as shown in Figure 1 lightning protection power distribution transformer, constitute by housing, iron core, coil, fuel tank, porcelain bushing, tap switch and other annexes, promptly keep under the constant prerequisite of common power distribution transformer design parameter and technical performance, on transformer housing loam cake 9, increase and adorn one group of lightning arrester and finish lightning-arrest function.
Purpose of the present invention can also reach by following measure: the lightning arrester of this lightning protection power distribution transformer is by lightning arrester 2 and porcelain bushing 1, sealing gusset piece 7 compositions such as grade, promptly three lightning arresters 2 are contained in respectively in three porcelain bushings 1, are inserted into the centre position that transformer shell is stopped loam cake 9.The lower end of three lightning arresters 2 is stopped loam cake 9 usefulness nuts with shell respectively and is fixed, and be immersed in the oil tank of transformer in the oil, and with being connected on ground connection on the housing after 7 parallel connections of sealing gusset piece, the upper end is connected by mistake line 5 with high voltage source binding post A, B, C respectively.
The drawing of accompanying drawing is described as follows:

The present invention is described in further detail below in conjunction with accompanying drawing: the lightning protection power distribution transformer is to keep under the constant prerequisite of common power distribution transformer design parameter and technical performance as shown in Figure 1, increases in the centre position of transformer housing loam cake 9 and adorns three lightning arrester F of a row
1, F
2, F
3Promptly three cylindricality zinc oxide arresters were contained in three high voltage porcelain bushing pipes 1 in 2 minutes in addition, the band sealing ring is inserted in the hole of the case top lid 9 that processes the hole, below loam cake 9, fix with nut, and with being connected on ground connection on the shell body behind copper sealing gusset piece 7 three lightning arrester lower ends in parallel, the upper end of lightning arrester 2 is connected with high voltage source binding post A, B, C by crossing line 5.The lower end of following in working order three lightning arresters is immersed in the interior oil of oil tank of transformer, must connect by crossing line 5 between high-voltage line power-line terminal and the lightning arrester binding post when dispatching from the factory, but when testing transformer coil and lightning arrester, must disconnect, when normal operation, must connect crossing line 5.
The present invention has following advantage compared to existing technology:
1, improved the reliability and sensitivity of the lightening protection of transformer, guaranteed to become Depressor is safe and reliable to operation at thunderstorm season;
2, prolong service life and the time between overhauls(TBO) of lightning protection device;
3, reduce installation, the recondition expense of transformer, can economize on the use of funds 1,000 yuan for every;
4, improve the operational environment of transformer platform, install, overhaul convenient safety again.
