Abstract

The utility model provides a novel 35kV PT fuse of switching mode, including casing and cap, annular support is installed at the casing top, and annular support has seted up first through -hole, has seted up the second through -hole on the cap, and first through -hole and second through -hole are the same cuboid of size, the cap through special bolt fastening on the casing, special bolt is equipped with the dog at the tip of double -screw bolt. The utility model provides a special bolt, it is later rotatory to insert the through -hole, because the major axis of dog and through -hole is greater than the minor axis, so the dog is blocked outside the through -hole, consequently special bolt just can easily be fixed casing and cap, easy operation, work efficiency improves greatly, has reduced long -time high altitude construction's danger.

Description

A kind of 35kV PT fuse of novel opening and closing mode
Technical field
The utility model belongs to field of electrical equipment, is specifically related to a kind of 35kVPT fuse of novel opening and closing mode.
Background technology
In recent years, in the above transformer station of electric pressure 35kV, PT fuse melting phenomenon often occurs, the safe and stable operation of electrical network in serious threat.The housing of traditional 35kVPT fuse clips and the connected mode of cap are fastened by screw mode, the Renewal process relative complex thus insured, inefficiency, lose time and the long-time easy dangerous property of work high above the ground.
Summary of the invention
For solving the problem, the utility model provides a kind of 35kVPT fuse of novel opening and closing mode.
The purpose of this utility model realizes in the following manner:
A kind of 35kVPT fuse of novel opening and closing mode, comprise housing and cap, described case top is provided with annular support, annular support offers the first through hole, cap offers the second through hole, the cuboid that first through hole is identical with sized by the second through hole, cap is fixed on housing by special bolt, and described special bolt is provided with block in the end of stud.
Described cap is fixed on being specially on housing by special bolt: cap and housing are fixed up by the first through hole and the second through hole by special bolt.
Described special bolt, the first through hole and the second through hole are at least two groups, are evenly arranged.
Described block is cuboid or Elliptic Cylinder.
The long axis length of described block is consistent with the major axis of the first through hole and the second through hole, and minor axis and the stud diameter of minor axis length and the first through hole, the second through hole are consistent.
Relative to prior art, the utility model is relative to prior art, and the beneficial effects of the utility model are:
Special bolt in the utility model, rotate after inserting through hole, because the major axis of block and through hole is greater than minor axis, so block is stuck in outside through hole, therefore housing and cap just can be fixed up by special bolt easily, simple to operate, operating efficiency improves greatly, reduces the danger of long-time work high above the ground.
Accompanying drawing explanation
Fig. 1 is the structural representation of fuse.
Fig. 2 is the vertical view of annular support.
Fig. 3 is a kind of structural representation of special bolt.
Fig. 4 is the another kind of structural representation of special bolt.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of 35kVPT fuse of novel opening and closing mode, comprise housing 1 and cap 2, described housing 1 top is provided with annular support 3, annular support 3 offers the first through hole 31, cap 2 offers the cuboid that the second through hole 21, first through hole 31 is identical with sized by the second through hole 21, cap 2 is fixed on housing 1 by special bolt 4, and described special bolt 4 is provided with block 41 in the end of stud 42.
Described cap 2 is fixed on being specially on housing 1 by special bolt 4: cap 2 and housing 1 are fixed up by the first through hole 31 and the second through hole 21 by special bolt 4.
Described special bolt 4, first through hole 31 and the second through hole 21 are at least two groups, are evenly arranged.
As shown in Figure 3 and Figure 4, described block 41 is cuboid or Elliptic Cylinder.
The long axis length of described block 41 is consistent with the major axis of the first through hole 31 and the second through hole 21, and minor axis and stud 42 diameter of minor axis length and the first through hole 31, second through hole 21 are consistent.
Specific works process of the present utility model is as follows:
Together with the housing of the fuse more finished changing is placed with cap, make through hole corresponding, when the block of special bolt and the major axis of through hole consistent time, special bolt can pass through the first through hole and the second through hole, then rotate, because the major axis of block and through hole is greater than minor axis, so block is stuck in outside through hole, therefore housing and cap are fixed up by special bolt.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for a person skilled in the art, do not departing under the utility model general idea prerequisite; can also make some changes and improvements, these also should be considered as protection range of the present utility model.
