The utility model content:
The utility model proposes a kind of valve side insulation system that is applicable to the guide rod type dc bushing, improve the Electric Field Distribution of valve side dc bushing, make it more evenly rationally.
The technical scheme that the utility model adopted is:
A kind of valve side insulation system that is applicable to the guide rod type dc bushing, comprise insulating board and corrugated cardboard, described insulating board and corrugated cardboard alternately parcel form and are installed in the valve side by flange bracket and raise on the seat, and the number of plies of insulating board and corrugated cardboard is pressed the electrode shape of the valve side insulation level of converter transformer and valve side dc bushing and decided.
As preferred embodiment of the present utility model, described insulating board and corrugated cardboard alternately parcel back pry on flange bracket by insulation blanket stud and insulation nut.
As preferred embodiment of the present utility model, described insulation system is provided with the bracing or strutting arrangement of fixing with the barrel of valve side rising seat at the middle part.
As preferred embodiment of the present utility model, described bracing or strutting arrangement comprises insulation collar ring and insulating paper circle, and described insulating paper circle is arranged in the insulation collar ring, and described bracing or strutting arrangement is held sturdy middle part at insulation system tightly by insulation crimped paper.
As preferred embodiment of the present utility model, described flange bracket is installed on the valve side rising seat by 6 by the securing member assembling.
As preferred embodiment of the present utility model, described insulation system has two covers, and two covers are bonded with insulation molding part between the insulation systems, and the shape of insulation molding part is pressed the electrode shape of the valve side insulation level of converter transformer and valve side dc bushing and decided.
The utility model has the following advantages at least: the utility model insulation system is rationally cut apart a converter transformer valve side rising seat oil clearance by insulating board and corrugated cardboard, the DC electric field, AC field and the direct-current polarity counter-rotating that improve converter transformer valve side mix electric field, and it is distributed more evenly rationally.

Embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
1, the utility model insulation system mainly by insulating board 4 and corrugated cardboard 5 alternately parcel forms and is installed in the valve side and raise on 1 by flange bracket 2, the number of plies of its insulating board 4 and length are decided according to the valve side insulation level of converter transformer and the concrete length of valve side dc bushing;
2, insulation system is assembled into an integral body and pries on a circular flange support 2 with insulation blanket stud 7 and insulation nut 8, and whole erection adopts support and install at 6 on the valve side raises seat 1 then, guarantees the concentricity that its fixing and valve side raise;
3, the middle part of insulation system is by the waist hoop of being made up of insulation collar ring 9 and insulating paper circle 10 (perhaps bracing or strutting arrangement), be used for insulation system is supported on the barrel of valve side rising seat 1, avoid transporting and the rocking of insulation system in service, increase its fail safe, described insulating paper circle 10 is arranged in the insulation collar ring 9, and described bracing or strutting arrangement is held sturdy middle part at insulation system tightly by insulation crimped paper 11;
4, insulation system transports with valve side rising seat band oil together or inflation, and on-the-spot the installation need not to assemble once more.
See also Fig. 1 to shown in Figure 4, the utility model guide rod type dc bushing valve side insulation system mainly is made up of two parts: a part replaces the seal that wraps up and form by insulating board 4 and corrugated cardboard 5, described insulation system has two covers, the internal layers of two cover insulation systems are bonded with insulation molding part 6, and the number of plies of insulating board 4 and corrugated cardboard 5 and the shape of insulation molding part 6 need be decided by the electrode shape of the valve side insulation level of converter transformer and valve side dc bushing; Another part is with insulation crimped paper 11 insulation collar ring 9 and insulating paper circle 10 to be packed tightly support and the protective device in the middle part of insulation system in a down-to-earth manner.These two parts are assembled into a whole back and pry on flange bracket 2 with insulation blanket stud 7 and insulation nut 8.And then this integral body is installed in the valve side with securing member assembling 3 by 6 raises on the seat 1.
