Abstract
The utility model relates to a kind of 35kV fuse, comprise a porcelain bushing (5), and the melt pipe (7) be arranged in porcelain bushing (5), be assemblied in the end cap (4) at porcelain bushing (5) two ends, stage clip (6) is provided with between the inner face of one of them end cap and the end face of melt pipe, it is characterized in that, one end external cylindrical surface of described porcelain bushing (5) coordinates and is installed with anchor ear (1), the relative both sides of anchor ear (1) are provided with the jig for fixing end cap (4).Adopt the utility model, under same fault, each repair time was down within 20 minutes by 120 minutes, reducing interruption duration, saving the Master Cost changing porcelain bushing because tearing to fall terminal open, reduce economic loss, ensure the stable operation of electrical network.
Description
Technical field
The utility model relates to high-tension electricity technical field, particularly a kind of 35kV high-tension transformer fuse.
Background technology
RWXO-35/0.5-2 type transformer fuse forms primarily of porcelain bushing, melt pipe and end cap, melt pipe is located in porcelain bushing, melt pipe is closed by the two ends that end cap is screwed in porcelain bushing, is provided with spring between the inner face of end cap and the end face of melt pipe, because the melt pipe fusing rate in porcelain bushing is higher, often need to change melt pipe, in the process changed, find that the structure of existing fuse exists following shortcoming: because fuse is located at outdoor, end cap fixed screw is easy to corrosion, dismounting difficulty, waste time and energy, whole fuse must be removed from framework and change, the time changed once is approximately 120 minutes, also often can there is terminal in addition not tear open not get off and the situation that melt pipe cannot be changed, at this moment will change together with porcelain bushing, a porcelain bushing 300 circle left and right, cause waste of material.
Utility model content
There is not easily detachable problem for existing fuse terminal, the utility model provides a kind of terminal the quick detachable 35kV fuse being convenient to change melt pipe.
For reaching above-mentioned purpose, the utility model adopts following technical scheme.
A kind of 35kV fuse, comprise a porcelain bushing 5, and the melt pipe 7 be arranged in porcelain bushing 5, be assemblied in the end cap 4 at porcelain bushing 5 two ends, stage clip 6 is provided with between the inner face of one of them end cap and the end face of melt pipe, it is characterized in that, one end external cylindrical surface of described porcelain bushing 5 coordinates and is installed with anchor ear 1, the relative both sides of anchor ear 1 are provided with the jig for fixing end cap 4.
Further, described jig comprises the clasp bearing 1a and pressure ring bearing 1b that are arranged at the relative both sides of anchor ear 1 respectively, and hinged clasp 3 on clasp bearing 1a, hinged pressure ring 2 on pressure ring bearing 1b, described pressure ring 2 coordinates with clasp 3 grafting.
Further, described pressure ring 2 is for there being the right angle pressure ring at 90 ° of bending angles, and the bending section 2a of pressure ring 2 to be pressed on end cap 4 and to be plugged in clasp 3.
Beneficial effect: adopt the utility model, under same fault, each repair time was down within 20 minutes by 120 minutes, reduce interruption duration, reducing economic loss, saving the Master Cost changing porcelain bushing because tearing to fall terminal open, ensure the stable operation of electrical network.
Accompanying drawing explanation
Fig. 1 is basic structure schematic diagram of the present utility model;
Fig. 2 is 3D illustraton of model of the present utility model;
Fig. 3 is partial sectional view of the present utility model.
Embodiment
A kind of 35kV fuse that the utility model provides, as Fig. 1, Fig. 2, shown in Fig. 3, comprise a porcelain bushing 5, and the melt pipe 7 be arranged in porcelain bushing 5, be assemblied in the end cap 4 at porcelain bushing 5 two ends, stage clip 6 is provided with between the inner face of one of them end cap and the end face of melt pipe, one end external cylindrical surface of described porcelain bushing 5 coordinates and is installed with anchor ear 1, the relative both sides of anchor ear 1 arrange clasp bearing 1a and pressure ring bearing 1b respectively, hinged clasp 3 on clasp bearing 1a, hinged pressure ring 2 on pressure ring bearing 1b, described pressure ring 2 is for there being the right angle pressure ring at 90 ° of bending angles, the bending section 2a of pressure ring 2 to be pressed on end cap 4 and to be plugged in clasp 3.
Operation principle is summarized as follows:
Anchor ear 1 is linked on porcelain bushing 5, and hinged clasp 3 thereon and pressure ring 2 coordinate and push down wiring end cover 4, and spring 6, by wiring end cover 4 jack-up, makes clasp 3 and pressure ring 2 be fixed, thus can not come off; When needing to open end cap replacing melt pipe, only need a compressing end cap downwards easily can open jig.
