Background technology
Installing and using in the process of existing high-voltage alternating demarcation circuit breaker, exposing outside of equipment into and out of line terminals and overhead transmission line junction, therefore exist following defective: 1) long term exposure is under sunlight and rainwater, and the equipment that makes is connected the exposed section accelerated oxidation into and out of line terminals with overhead transmission line; 2) equipment is connected the exposed section into and out of line terminals and gathers dirt easily and cause alternate increase to climb the probability of arc with overhead transmission line, influences the life-span behind the switch performance; 3) after equipment was installed and used, it exposed outside into and out of line terminals and overhead transmission line junction, piles up sleet outside sleety weather equipment, causes the equipment phase fault easily, causes device damage.
Summary of the invention
Goal of the invention: the purpose of this utility model is to address the above problem; provide a kind of high-voltage alternating demarcation circuit breaker into and out of line terminals insulation protection sleeve pipe; can make into and out of the exposed position of line terminals and not be subjected to extraneous weather effect, guarantee the switch performance of circuit breaker.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme: a kind of high-voltage alternating demarcation circuit breaker is into and out of line terminals insulation protection sleeve pipe, comprise the insulation body that rubber is made, described insulation body comprises the front sealing section that is used to wrap up external cable, be used to protect external cable with into and out of the middle part parcel section of connector between the line terminals be used for and the rear portion stiff end that is connected into and out of line terminals; One side of middle part parcel section is opened wide.
Wherein, the internal diameter of described front sealing section is increased to wrapping up a section junction with the middle part gradually by the end.
Wherein, the inwall of described front sealing section is step-like.
Wherein, the both sides tube wall at the unlimited place of parcel section, described middle part is provided with adaptive buckle mutually.
Wherein, described rear portion stiff end is and the suitable clip of outer wall projection into and out of the line terminals insulating barrier.
The utility model has the advantages that: 1) seal section of insulation protection sleeve pipe adopts the design of staged reducing, can adapt to the external cable of different outer warps, and the stiff end of insulated tube adopts the clamping hoop type structure, with fixing more firm into and out of line terminals; 2) insulation protection sleeve pipe middle part is designed for semi-open-type, also is provided with buckle at unlimited place, makes the construction and installation process easier, efficient; Can improve the non-maintaining property of protective switchgear effectively; 3) compact conformation of insulation protection sleeve pipe, space hold are little, and not only packing and convenient transportation and assembling process are easier, efficient; 4) the insulation protection sleeve pipe divides A Huang, green, the red three kinds of colors of C of B, can solve circuit A, B, C three-phase effectively and distinguish problems such as not obvious, makes it carry circuit and switchgear uses, operational safety performance is higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Fig. 3 is a scheme of installation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
As illustrated in fig. 1 and 2; of the present utility modelly comprise an insulation body of making by silicon rubber, described insulation body comprises the front sealing section 1 that is used to wrap up external cable, be used to protect external cable with into and out of the middle part parcel section 2 of connector between the line terminals be used for and the rear portion stiff end 3 that is connected into and out of line terminals.The tube wall of front sealing section 1 is step-like, and the tube wall internal diameter to increasing gradually with parcel section 2 junctions, middle part, can adapt to the external cable of different outer warps by the end like this.One side of middle part parcel section 2 is opened wide, and is provided with adaptive buckle 4 mutually on the both sides tube wall that opens wide the place.Rear portion stiff end 3 be with into and out of the suitable clip of the outer wall of line terminals insulating barrier projection.The clip inwall is provided with annular ditch groove, and the internal diameter of annular ditch groove is slightly less than into and out of the maximum outside diameter of the outer wall projection of line terminals insulating barrier, and the groove width of annular ditch groove is slightly less than into and out of the thickness of the outer wall projection of line terminals insulating barrier.
As shown in Figure 3, after the insulation protection sleeve pipe installed, the clip at its rear portion just in time was enclosed within on the outer wall projection of line terminals insulating barrier, was wrapped in the middle part parcel section 2 into and out of the conducting rod of line terminals front end., the less one section sanction of the tube wall internal diameter of front sealing section 1 is gone when line terminals is connected with external cable at equipment, external cable is filled in by the front end of insulation protection sleeve pipe, front sealing section 1 tightly is wrapped in the external cable outside; Carry out external cable and into and out of the installation of connector between the line terminals by the open ports of middle part parcel section 2, the buckle 4 that installs again the open ports place fastens.
The insulation protection sleeve pipe that is installed on the line terminals is divided into color in the Huang, green, red three, and yellow insulating sleeve corresponding A is into and out of line terminals, and the corresponding B of green insulating sleeve is into and out of line terminals, and red insulating sleeve correspondence C is into and out of line terminals.Because conducting rod the stretch out section of A into and out of line terminals and C into and out of line terminals is bending-like, the yellow insulating sleeve corresponding and the middle part of red insulating sleeve with it wrap up sections 2 and the junction of rear portion stiff end 3 also make corresponding bending-like.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
