Description
Technical field
The utility model belongs to the structural member technical field of high-tension switch gear current transformer outlet protection, installation, tool
Body is related to a kind of threading protection installation bend pipe for current transformer.
Background technology
In the existing threading protection installation bend pipe for current transformer, welded together using 2 parts
Bend pipe, thread segment aperture is small, has step so that production threading process is difficult, is obstructed.And there is following defects：
1st, the threading protection installation bend pipe of welding is in part process, and thread segment needs to use pole machine-shaping, so
Combination Welding afterwards, not only waste of materials, and processing, welding process are not environmentally；
2nd, because the threading protection installation bend pipe thread segment aperture of welding is small so that electric wire is obstructed in production assembling process,
Cause assembly time long, waste assembling manpower；
3rd, in production and assembling process, current transformer line passes through the installation bend pipe of welding, be easy to cause the outer of electric wire
Insulating layer is damaged, makes current mutual-inductor parameter mistake, can cause switchgear maloperation.
Utility model content
The utility model proposes a kind of threading protection installation bend pipes for current transformer, are integrally formed by setting
Bend pipe, convenient for disassembly and assembly using thread connecting mode, good airproof performance improves the safety of electric product.
What the technical solution of the utility model was realized in：
A kind of threading protection installation bend pipe for current transformer, including winding pipe assembly, current transformer and high pressure
Babinet is switched, the high-voltage switch gear babinet is fixedly connected with current transformer by the winding pipe assembly, the winding pipe assembly packet
Include elbow body, sealing ring and hex nut, the elbow body one brake forming, including vertical section and horizontal segment, institute
Horizontal segment is stated equipped with thread segment and the first collar, the high-voltage switch gear wall box is equipped with mounting hole, and the thread segment is inserted
It is connected in the mounting hole, the sealing ring is arranged between the mounting hole and the first collar, and the hex nut is tightened in
On the thread segment, the vertical section is fixedly connected on the current transformer bottom.
In the threading protection installation bend pipe for current transformer of the utility model, first collar and bend pipe sheet
Body by integral forming.
In the threading protection installation bend pipe for current transformer of the utility model, set on the high-voltage switch gear babinet
There is knob.
Implement this threading protection installation bend pipe for current transformer of the utility model, have below beneficial to effect
Fruit：
1st, the design of threading installation bend pipe is simple, and aperture is big, can Quick-threading, dismounting is more convenient.
2nd, bend pipe uses hydraulic integrated, it is ensured that good leakproofness can effectively improve the safety of electric product
Property.
3rd, bend pipe installation is convenient for disassembly and assembly using thread connecting mode without welding, and can save component built-up time.
Description of the drawings
Fig. 1 is the scheme of installation of the threading protection installation bend pipe for current transformer of the utility model；
Fig. 2 is the schematic diagram of the threading protection installation bend pipe for current transformer of the utility model.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
This threading protection installation bend pipe for current transformer of the utility model as shown in Fig. 1 to 2, including
Winding pipe assembly 1, current transformer 2 and high-voltage switch gear babinet 3, the high-voltage switch gear babinet 3 are equipped with knob 30.The height presses off
It closes babinet 3 to be fixedly connected by the winding pipe assembly 1 with current transformer 2, winding pipe assembly 1 and high-voltage switch gear babinet 3 and electric current
Mutual inductor 2 all using being threadedly coupled, improves dismounting convenience, shortens built-up time.The winding pipe assembly 1 includes bend pipe sheet
Body 11, sealing ring 13 and hex nut 14, the integrated brake forming of elbow body 11, elbow body 11 use hydraulic test liquid
Pressure is integrally formed, easy to process, good seal performance.It includes vertical section 4 and horizontal segment 5, and it is mutual that vertical section 4 is fixedly connected on electric current
2 bottom of sensor, horizontal segment 5 are fixedly connected on 3 side wall of high-voltage switch gear babinet.The horizontal segment 5 is equipped with thread segment 41 and the
One collar 42,41 and first collar 42 of thread segment also use hydro-forming.3 side wall of high-voltage switch gear babinet is equipped with mounting hole
31, which is more than 41 outer diameter of thread segment, but less than the diameter of the first collar 42.The thread segment 41 is plugged on institute
It states in mounting hole 31, the sealing ring 13 is arranged between 31 and first collar 42 of mounting hole, can play the work of sealing
With.The hex nut 14 is tightened on the thread segment 41, improves the convenience of installation in this way.
The installation procedure of this case is：First sealing ring 13 is socketed on thread segment 41, thread segment 41 is then passed through into installation
Hole 31, toward thread segment 41 on screw on hex nut 14, complete the installation of elbow body 11.Whole device connection is easy, saves very much
Save built-up time.So far, the present utility model purpose is accomplished.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
