Abstract
The utility model relates to a sleeve tube fuse used in an indoor and outdoor voltage transformer on a 10KV distribution network and a primary incoming line of single phase matching change below 5KVA. The utility model is composed of a hollow insulating indoor and outdoor insulating sleeve tube, a copper body, a spring, a forming fusion body and a press fixing sealing cap of the forming fusion body, etc. The utility model not only has the functions of insulating isolation and insulating support of the primary incoming line, but also has the functions of overload and short circuit protection of a primary circuit. The utility model has the advantages of simple structure and high operational reliability, and is a multipurpose part which forms a novel voltage transformer.
Description
The utility model relates to a kind of cover tubular fuse-link, and it is indoor on a kind of 10KV power distribution network, the member of external voltage instrument transformer or the support body that dry type is partly poured into a mould voltage transformer, is applicable to insulation, isolation and support and the protection of an inlet wire of voltage transformer.
At present, the 10KV voltage transformer of China's distribution online operation, inlet wire of indoor type is connected in series into network operation with high-tension fuse.Outdoor type directly inserts the distribution operation because of the distribution net work structure restriction can't be connected in series high-tension fuse.Like this, the voltage transformer fault is the impact system power distribution network often, has reduced the reliability of power distribution network safe operation to a certain extent.In addition, though the indoor type voltage transformer once is connected in series networking with high-tension fuse, possessed overload and short-circuit protection function.But increased loop conductive junction point and system fault point over the ground, complicated distribution net work structure is still threatening the safe operation of power distribution network.
The purpose of this utility model is the existing drawback of voltage transformer at present 10KV distribution online operation, a kind of cover tubular fuse-link of voltage transformer is provided, make the indoor external voltage instrument transformer online of 10KV simple in structure, loop conductive junction point and the corresponding minimizing in fault point over the ground improve the reliability of power distribution network safe operation.
The purpose of this utility model following measure of can leading to realizes: the cover tubular fuse-link is by connection bolt, the typing melt presses solidly rainhat, interior cover, the indoor external insulation sleeve pipe, the copper body, spring, compositions such as typing melt, indoors the radial center of external insulation casing pipe has the inner chamber of a cup-shaped, be fixed with a copper body in the bottom of inner chamber, the top of copper body have be loaded on spring inner chamber and that be electrically connected with the copper body and the typing melt, indoors the inner chamber internal fixation of external insulation casing pipe upper end has cover in, in have with the typing melt in the cover and press solidly the internal thread that the external screw thread of rainhat lower end is complementary, the connection bolt that is electrically connected with the typing melt is arranged in the upper end of cover tubular fuse-link, interior cover and typing melt press solidly rainhat and are electrically connected with the typing melt, and indoors there is 2-6 umbellate form cap the outside of external insulation casing pipe.
The purpose of this utility model can also realize by following measure:
The upper end that presses solidly rainhat at the typing melt is installed with connection bolt.
Be fixed in the indoor external insulation cannula cavity in put a terminal block that stretches out the outer end and on terminal block, be installed with connection bolt.
On the indoor external insulation sleeve pipe of umbellate form cap bottom, flange is arranged, the bolt hole is arranged on flange.
One time outer indoors partly the cast on the dry-type voltage inductor of winding leads set bolt is to be embedded in the epoxy resin poured body.Its cover tubular fuse-link and a winding are common indoor outer epoxy resin pour mass.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the cut-away view of the cover tubular fuse-link of outdoor oil immersed type voltage transformer
Fig. 2 is the cut-away view of the cover tubular fuse-link of indoor oil immersed type voltage transformer
Fig. 3 is the outline drawing of the cover tubular fuse-link of indoor outer half cast-type voltage transformer
Fig. 4 is the A-A cutaway view of the cover tubular fuse-link of indoor outer half cast-type voltage transformer
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 be outdoor oil immersed type voltage transformer the cover tubular fuse-link it press solidly rainhat 2, interior cover 3, indoor external insulation sleeve pipe 4, copper body 6, spring 7, typing melt 8 etc. by connection bolt 1, typing melt and form.The radial center of the indoor external insulation sleeve pipe 4 that epoxy resin evacuated die-casting process forms outside employing is indoor has the inner chamber of a cup-shaped, in the die casting of the bottom of inner chamber copper body 6 is arranged, copper body 6 bottoms are winding leads bolt 9 once, have on the top of copper body 6 and to be loaded on spring 7 inner chamber and that be electrically connected with the copper body and typing melt 8, the interior die casting of the inner chamber of external insulation casing pipe 4 upper ends indoors has in one overlaps 3, in cover have in 3 with the typing melt and press solidly the internal thread that the external screw thread of rainhat 2 lower ends is complementary, the top that melt on the top of overlapping tubular fuse-link presses solidly rainhat 2 is installed with connection bolt 1, ring inner sleeve 3 and typing melt press solidly rainhat 2 and are electrically connected with typing melt 8, indoors there are 4 umbellate form caps the outside of external insulation casing pipe 4, a square or circular flange 5 is arranged on the indoor external insulation sleeve pipe 4 of umbellate form cap bottom, the bolt hole is arranged on flange 5.
Fig. 2 is the cover tubular fuse-link of indoor oil immersed type voltage transformer, and it has a terminal block that stretches to the outer end to be rotary with connection bolt 1 on interior cover 3 on terminal block, and indoors there are 2 umbrella hats the outside of external insulation casing pipe 4.
Fig. 3 and Fig. 4 are the indoor outer cover tubular fuse-links of partly pouring into a mould dry-type voltage inductor, and its indoor external insulation sleeve pipe 4 directly is cast in the voltage transformer winding, achieves a fixed connection.
The utility model has not only been saved high-tension fuse compared with prior art, and has purified and join Web frame has reduced over the ground trouble point of loop conductive junction point and system. The indoor external voltage transformer of 10KV Use sleeve fuse, have that online is simple in structure, a small investment, operational reliability advantages of higher.
