Arm-tie adds collar and connects, arm-tie is to be stamped into " L " shape with steel plate, and have some radians, width is no more than 100mm, the lower end is welded with the gauge finder of fastening bolt, it is circular that collar is that 6 * 60mm steel band is welded into, behind the arm-tie, with collar ring cover, the fastening bolt on the arm-tie passes fuel tank cap flange connecting hole on the cloth of high-pressure insulating ring pipe clamp platform outer ring, spacing by fastening arm-tie and collar, the sealing that reaches fuel tank and high-tension insulating bushing is fastening, owing to be subjected to dispersed transportation vibration of high-tension insulating bushing self production technology and the long-term stress deformation of arm-tie, being in operation is prone to oil seepage phenomena, install loaded down with trivial details in addition, bad operation, behind the product long-play, high-tension insulating bushing and fuel tank cap flange connecting portion have dirt, easy-to-rust, not easy-clear.
The trim ring pressurizing block connects, trim ring is that the cross section is the annulus of " L " type, be distributed with connecting hole all around, the briquetting cross section is the annulus of stairway step shape, for the ease of installing, be divided into 2-3 arc piece, briquetting Ka Tai is placed on the high-tension insulating bushing step, " L " face of trim ring is placed on the step surface of briquetting, and middle pad is gone up rubber ring, and the connecting hole of trim ring passes the bolt that welds on the fuel tank cap, compress trim ring by the rotation nut, band presses piece simultaneously, play being tightly connected of high-tension insulating bushing and fuel tank,, seepage oil can occur after the product long-time running because rubber ring is subjected to operation of nature to be easy to weathering after stressed, in addition, fastening bolt is to be welded on easily to produce the temperature distortion phenomenon on the fuel tank cap flange, often occurs interim the correction when assembling, prolongs installation time.
Summary of the invention
This utility model is to be solved be exactly the connection of present existing paper oil insulation current transformer product high-tension insulating bushing all be to adopt arm-tie to cooperate or trim ring and briquetting fit system and the easy to leak oil in service that brings, loaded down with trivial details, the bad operation of installation, problem such as perishable with collar, provide a kind of new high-tension insulating bushing to connect, make the oil impregnate that is difficult in service, and novel simply and easily paper oil insulation high-tension current inductor is installed.
Solve the technical scheme that its technical problem adopts: this paper oil insulation high-voltage mutual inductor, by fuel tank, the device body that winding and secondary winding are merged into, high-tension insulating bushing, the primary connection terminal, secondary connection plate and expander are formed, the device body is to be fixed in the fuel tank, high-tension insulating bushing passes a winding of device body, two ends respectively with fuel tank on fuel tank cap flange and expander be tightly connected, the primary connection terminal is connected with a winding, the secondary connection plate is connected with secondary winding, it is characterized in that: all glued joint at the two ends of high-tension insulating bushing cast iron flange, the cast iron flange of upper end is connected with the expander base plate, the expander base plate is provided with the base plate seal groove, the base plate sealing ring is installed in the base plate seal groove, fastening with fastening bolt, the cast iron flange of lower end is connected with the fuel tank cap flange on fuel tank top, have the fuel tank cap seal groove on the fuel tank cap flange, fuel tank cap flange seal circle is installed in the fuel tank cap seal groove, fastening with fastening bolt.
Described cast iron flange is the boss shape.
Beneficial effect: cooperate crimping or trim ring to cooperate the crimping method of attachment to compare with briquetting with the arm-tie and the collar of prior art mesohigh insulating sleeve, the utlity model has following advantage: 1. because fuel tank cap flange and expander base plate all are processed with seal groove, and sealing ring is installed to be embedded in the seal groove, make whole complete combination of adpting flange and connecting plate, the product that not only efficiently solves the original device assembling is under the long-time running state, the elastic force distortion, it is loosening fastening bolt to occur, the product oil seepage phenomena, but also prevented sealing ring for a long time by ultraviolet irradiation, easily aging problem; 2. pour into a mould the high-tension insulating bushing of flange and fuel tank, the expander method of attachment is simple, easy to operate, increase work efficiency.
