Abstract
The utility model relates to the protection technology of a traveling crane in transformer production, and discloses a dustproof device of a traveling crane movable pulley group in transformer production. The dustproof device comprises a front protection cover and a rear protection cover which are fixed onto an outer casing of the movable pulley group. Outer turnups are arranged on the lateral surfaces of the front protection cover and the rear protection cover; a casing is formed by the front protection cover and the rear protection cover after being connected through the outer turnups; the casing is provided with an open upper portion and an opening lower portion; and inner turnups are arranged on the opening of the lower portion of the casing.
Description
Technical field
The utility model relates to the guard technology of transformer production middle rolling car, particularly a kind of dust guard of transformer production middle rolling car running block.
Background technology
As everyone knows, the mechanical impurities particle in the transformer oil has a significant impact its insulation property.Impurity particle can form foot bridge or particle chain under effect of electric field, produce partial discharge, reduces the dielectric strength of transformer oil.Under electric field action, discharge capacity is very little for minute impurities particle (less than 150 μ m).Though the large granular impurity number is seldom, to compare with these a large amount of molecules, they are even more serious to the insulation property influence of transformer oil, and the bulky grain under electric field action is one of principal element that produces partial discharge.When impurity particle was conductive particle, the surface electric field intensity that they produce under the effect of electric field outside was much larger than adding field intensity, and when surpassing the disruptive field intensity of transformer oil, corona discharge just takes place these particle surfaces.Under bare electrode, bigger conductive particle and electrode near the time, local field strength increases greatly between the two, causes local micro discharge, produces with bubble simultaneously, partial discharge is further strengthened, and cause the transformer oil breakdown strength further to descend.
The running block of driving generally is not with dust guard, but the inventor finds son and is positioned in the lifting process, fricative metallic particles and machine oil drop easily between cable wire and the pulley, become large granular impurity in the transformer oil, have a strong impact on the insulation property of oil.
Summary of the invention
The purpose of this utility model is to provide a kind of dust guard of transformer production middle rolling car running block, can prevent effectively that fricative metallic particles and machine oil drop between cable wire and the pulley, avoids polluting transformer oil and device body.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of dust guard of transformer production middle rolling car running block is characterized in that, comprises the forward and backward protective cover that is fixed on the running block shell; The side of described forward and backward protective cover all has flanging, and forward and backward protective cover connects the back by flanging and forms the housing with open topped and lower openings; Described lower part of frame opening has in-flanges.
Further improvement of the utility model and characteristics are:
Described forward and backward protective cover is that the brace of Z type is fixed on the running block shell by a cross section, and its middle section is that an end of the brace of Z type is fixed on the running block shell, and the other end is fixed between the flanging of forward and backward protective cover side.
Be provided with rubber gasket between the flanging of described forward and backward protective cover side.
The utility model is provided with the housing of being made up of forward and backward protective cover with open topped and lower openings on middle running block shell, the lower part of frame opening has in-flanges.The lower part of frame opening is used to stretch out the suspension hook of running block, and the open topped of housing is used to collect fricative metallic particles and machine oil between cable wire and the pulley, thereby avoids polluting transformer oil and device body.
In addition, forward and backward protective cover is that Z type brace is fixed on the running block shell by a cross section, and wherein an end of Z type brace is fixed on the running block shell, and the other end is fixed between the flanging of forward and backward protective cover side, the convenient connection; Be provided with rubber gasket between the flanging of forward and backward protective cover side, guarantee that the foreign material of collection can not missed.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Fig. 1 looks schematic diagram for the master of preceding protective cover in the dust guard of a kind of transformer production middle rolling car running block of the present utility model;
Fig. 2 is the schematic top plan view of Fig. 1;
Fig. 3 is the dust guard device schematic diagram that is assemblied on the running block;
Fig. 4 is the schematic diagram of the brace of Z type for the cross section, and wherein (a) looks schematic diagram for the right side, (b) is the main schematic diagram of looking.
Embodiment
With reference to Fig. 1, Fig. 2, protective cover 1 before in the dust guard of a kind of transformer production middle rolling car running block of the present utility model, back protective cover and preceding protective cover symmetry, forward and backward protective cover side all has flanging 2, the flanging 2 that passes through of the two connects the housing that back formation has open topped and lower openings, and the lower part of frame opening has in-flanges 3.
In conjunction with Fig. 3, Fig. 4, forward and backward protective cover is that the brace 4 of Z type is fixed on running block 5 shells by a cross section, its middle section is that an end of the brace 4 of Z type is fixed on running block 5 shells, and the other end is fixed between the flanging 2 of forward and backward protective cover side; Be provided with rubber gasket between the flanging 2 of forward and backward protective cover side simultaneously.
The lower part of frame opening is used to stretch out the suspension hook 6 of running block 5, and the open topped of housing is used to collect fricative metallic particles and machine oil between cable wire and the pulley, thereby avoids polluting transformer oil and device body.
