Abstract
The invention discloses a device for stretching a corrugated tube expander during oil charging after high-voltage oil charging equipment used in electric power industry is overhauled. The device comprises a screw rod, groove steel, top columns, connecting plates and the like and is characterized in that the top column is welded on the groove steel; the screw rod and a nut are arranged in the middle of the groove steel; the connecting plates are arranged on the screw rod; the lower ends of the top columns are placed on oil charging equipment during oil charging; holes in the connecting plates are respectively sleeved on an oil charging nozzle at the upper end of the corrugated tube expander and an air exhaust nozzle, and the nuts on the screw rod are tightly screwed, so that the corrugated tube expander can be stretched; and therefore, oil can be easily charged in a relaxing and labor-saving mode.
Description
Technical field
The present invention relates to a kind of stretching device of electric power high voltage oil-filled equipment inner corrugated pipe expander.
Background technology
The high voltage oil-filled equipment (like LB6-110W3 type 110kV current transformer) that power industry is used is interior for oil and air is isolated; Bellow expander is equipped with in upper end at oil-filled equipment; Be used for cushioning the bulbs of pressure that insulating oil produces because of variations in temperature, when the volume of insulating oil increased with the temperature rising, bellow expander can be stretched; So just make the pressure of oil in the oil-filled equipment keep constant basically, thereby guaranteed equipment safety operation.But when maintenance of equipment, it is oil-filled to drain the oil again, need make bellows expansion with the oiling of high pressure oiling machine; If the scene does not have the high pressure oiling machine, bellows is in compressive state, if oil-filled back temperature descends; Bellow expander just not have the capacity that enough shrinks, causes device interior generation negative pressure and suck air makes the equipment insulation degree decline of making moist, therefore; After need stretching bellow expander during oiling fill with oil, the bellow expander that stretch need be used bigger power, draws with manpower; Require great effort very much, and be not easy to operation.
Summary of the invention
The object of the invention overcomes deficiency of the prior art exactly, and a kind of bellow expander stretching device is provided.
Technical scheme of the present invention to achieve these goals is:
A kind of bellow expander stretching device; Form by leading screw, channel-section steel, fore-set, win in succession etc., it is characterized in that: be welded with two fore-sets (7) at the two ends of channel-section steel (3), leading screw (1) is housed in the interstitial hole of channel-section steel (3); Nut (2) is arranged on the leading screw (1); Be welded with screw rod (8) in the lower end of leading screw (1), the two ends of screw rod (8) are equipped with respectively and are won in succession (5) and nut (4), and porose (6) are gone up in win in succession (5).Lower end with two fore-sets (7) during oiling is placed on the equipment; Hole (6) on two win in succession (5) is enclosed within respectively on the pump nozzle and the mouth of bleeding of bellow expander upper end; Screw nut (2) on the leading screw (1); The bellow expander that just can stretch after the stretching is filled with oil, has just accomplished the oiling operation easily.
By above-described bellow expander stretching device, it is characterized in that: weld two sections channel-section steels (10,11) in the both sides, middle part of channel-section steel (3) respectively, form the cross bath steelframe, be welded with fore-set (7) in channel-section steel (10,11) end.Having processed like this has the bellow expander of 4 fore-sets stretching device, can be placed on stably on the oil-filled equipment, reduces operating personnel, realizes one man operation.
The beneficial effect that the present invention compares prior art is:
Simple to operate, laborsaving, easy to use, be easy to carry; Reduce operating personnel; Processing is simple, and cost is low, instead high pressure oiling machine, saving fund.
