Abstract
The invention discloses a sealing connecting method of insulating busways. The sealing connecting method of the insulating busways comprises a first step of correspondingly connecting a plurality of busbars of the two insulating busway so as to form a busway connector, a second step of fixedly connecting outer shells of the two insulating busways through cover plates, wherein the cover plates surround the busway connector and form a busway connector outer shell with one open face, a third step of casting liquid ceramic silicone rubber on the busway connector from an opening of the busway connector outer shell, wherein the busway connector outer shell is filled with the liquid ceramic silicone rubber, and a fourth step of covering the opening of the busway connector outer shell through the cover plates, wherein two ends of each cover plate are fixedly connected with the outer shells of the two insulating busways respectively. Through the sealing connecting method of the insulating busways, each gap of the busway connector can be filled with the liquid ceramic silicone rubber, and therefore sealing performance and insulation performance are good. Due to the fact that the liquid ceramic silicone rubber has excellent flame retardant fire-resistant characteristics, even if duration of fire resistance of the liquid ceramic silicone rubber is exceeded and the liquid ceramic silicone rubber burns, a hard protective shell can be formed through ablation, and the busbars in the ceramic silicone rubber are prevented from being damaged.
Description
Technical field
The present invention relates to a kind of seal connecting method of isolated bus groove.
Background technology
Be provided with some buses in the intensive isolated bus groove, these buses (bus line) are made with copper (copper bar), the aluminum material of high conductivity, in order to electric energy transmitting, have the product that compiles and distribute electric power.
The bus of intensive isolated bus groove is in the electric energy transmission course, carrying big electric current, high voltage, the bus product has high requirement to insulation property, fire resistance, therefore, how two intensive isolated bus grooves are formed the urgent problem that is connected to become of good insulation properties and fire resistance.
Summary of the invention
The object of the present invention is to provide a kind of seal connecting method that makes the isolated bus trough connection have insulation, fire resistance excellence.
For achieving the above object, the invention provides a kind of seal connecting method of isolated bus groove, formed by following steps:
At first, with some busbars of two isolated bus grooves respectively correspondence be connected to form the bus duct joint;
Secondly, with the shell of the fixedly connected two isolated bus grooves of cover plate, cover plate surrounds the bus duct joint and form the bus duct joint shell of an opening;
Then, be cast on the bus duct joint and fill up the bus duct joint shell from the opening part of bus duct joint shell with liquid ceramics silicon rubber;
At last, covering with the opening of cover plate with the bus duct joint shell, fixedlys connected with the shell of two isolated bus grooves respectively in these cover plate two ends.
Preferably, described formation bus duct jointing method is that some busbars of two isolated bus grooves are connected by brace is corresponding respectively, isolate by the insulating barrier insulation between the adjacent brace, and with some insulating barriers with screw or bolt together.
Preferably, described liquid ceramics silicon rubber mainly is made up of liquid silastic, silicon dioxide, silicone oil, coupling agent, Vitrified powder.For example, liquid ceramics silicon rubber is formulated with liquid silastic 100 weight portions, silicon dioxide 20～100 weight portions, silicone oil 1～20 weight portion, coupling agent 0.1～10 weight portion, Vitrified powder 20～120 weight portions.
Preferably, described liquid ceramics silicon rubber further comprises blowing agent.
Preferably, described liquid ceramics silicon rubber further comprises fire retardant
The beneficial effect of the seal connecting method of isolated bus groove of the present invention: employing liquid ceramics silicon rubber is cast on the bus duct joint and fills up the method for described bus duct joint shell; can make liquid ceramics silicon rubber be full of each slit of bus duct joint; therefore sealing and insulating properties are good; moreover; potteryization silicon rubber has the excellent fire retardant fire-resistance property; even surpassing the fire endurance burning still can ablate and form hard containment vessel; containment vessel can prevent that flame from further extending to the busbar of busbar insulation tank; thereby protection is positioned at the busbar of potteryization silicon rubber not to be damaged; guarantee the normal function of use of busbar, improved security of products.
