The DC bus bar insulating support has the advantages of scientific structure, convenient replacement of the insulators, and uniform pressure on the insulating support, and can overcome the disadvantages in the prior art.
Description
Technical field
The present invention relates to a kind of DC convergent current bus bar, particularly a kind of insulating support of DC convergent current bus bar.
Background technology
At coloured electrolysis plant, the rectifier transformer unit is sent to bus rod through the direct current branch bus after alternating current is become direct current, is sent to potroom by bus rod again.Branch bar is welded on the bus rod, bus rod at the scene one section one section be welded.Be installed in outdoor bus rod, utilize insulating support to play the effect of supporting bus and insulation.Insulating support is made up of supporters such as insulator and channel-section steels.Find that according to practical operation situation insulator can damage after a period of time.It is stressed that the insulating support that uses can't utilize the jack transfer at present, makes the bolt of fixed insulation be subjected to downward pressure when not having jack, when using jack, the bolt on all fixed insulation must be come loose very inconvenience of feasible dismounting; And it is not enough to be fixed on the bolt reservation operations space of facing the insulator inboard mutually, therefore causes insulator to change difficulty.It is very dangerous to change insulator.
Summary of the invention
Technical problem to be solved by this invention is, a kind of DC convergent current bus bar insulator bracket of scientific structure is provided, and can change insulator easily, can make the insulating support uniform-compression simultaneously, to overcome deficiency of the prior art.
Technical scheme of the present invention: it comprises insulator 2, and every group of insulator 2 is fixed between a lower supporting plate 1 and the upper backup pad 3 by first bolt 4; Lower supporting plate 1 is fixed on the lower carriage 8; On upper backup pad 3, be fixed with support 5; Above support 5, be provided with upper bracket 10, below upper bracket 10, be fixed with second supporting bracket 9 that equates with 2 groups of numbers of insulator, be supported on the corresponding support 5 being connected with second bolt, 7, the second bolts 7 on second supporting bracket 9.In insulator 2 upper and lower settings supporting brackets, can make insulator stressed more even; The support 5 and second bolt 7 are set make the operating space on insulator 2 tops increase, can also make the insulating support pressurized more even by regulating second bolt, 7 degrees of tightness.
Above-mentioned DC convergent current bus bar insulator bracket, the quantity of every group of insulator 2 are 4.
Aforesaid DC convergent current bus bar insulator bracket is fixed with first supporting bracket 6 on support 5.Can make support 5 pressurizeds more even like this.
Aforesaid DC convergent current bus bar insulator bracket, second bolt, 7 scalable, second bolt, 7 quantity that connect on every second supporting bracket 9 are 2.
Aforesaid DC convergent current bus bar insulator bracket is fixed with the 3rd supporting bracket 12 on upper bracket 10.Can make upper bracket 10 pressurizeds more even like this.
Aforesaid DC convergent current bus bar insulator bracket is provided with round steel 11 above the 3rd supporting bracket 12.
Aforesaid DC convergent current bus bar insulator bracket, the quantity of round steel 11 are 2～3.
Aforesaid DC convergent current bus bar insulator bracket, support 5, lower carriage 8, upper bracket 10 are channel-section steel.
Aforesaid DC convergent current bus bar insulator bracket, second bolt 7 is a high strength bolt more than 8.8 grades or 8.8 grades, diameter is not less than 30 millimeters.Second bolt 7 need bear the weight of bus rod and insulating support the first half, and 8.8 grades of high strength bolt ultimate loads that the diameter of selecting for use is 30 millimeters are 33.7 tons, can satisfy instructions for use fully.
Aforesaid DC convergent current bus bar insulator bracket, all supporting brackets are steel plate.
Compared with prior art, when the present invention changed insulator at needs, the jack that is lined with insulation board with the bottom withstood the ends A place of upper bracket 10, the weight of bus rod can be transferred on the jack, and promptly the bolt 4 of fixed insulation 2 does not stress; Cooperate degree of tightness second bolt 7 can be simultaneously, can avoid destroying the pad between bus and the insulating support at other positions so that the upper and lower displacement of bus rod minimizes.Scientific structure of the present invention, can change insulator easily, simultaneously can make the insulating support uniform-compression, guarantee that potroom uninterruptedly produces, great practical value is arranged, suitablely promote on a large scale.
