Description
Technical field
The present invention relates to circuit protection fields, and in particular to a kind of compound insulation type fuse.
Background technique
Fuse is commonly called as fuse, refers to when electric current is more than specified value, so that melt is fused with the heat that itself is generated, breaks
A kind of electric appliance of open circuit, fuse be according to electric current be more than specified value for a period of time after, with its own generate heat make to melt
Body fusing, so that circuit be made to disconnect；With a kind of current protector made of this principle.Fuse is widely used in high-low pressure
It is using most common protection as the protector of short circuit and overcurrent in distribution system and control system and electrical equipment
One of device.But if circuit to be protected is in the fuel tank of oil medium insulation, such as power transformer, if will melt
Disconnected device is mounted in fuel tank, needs to dismantle in transformer then fuse is replaced when fusing because protecting circuit, this can pole
The earth increases maintenance difficulties.If fuse is mounted on outside fuel tank, the circuit in fuel tank needs to draw by casing, then
It is connected again with fuse, equipment cost can be increased due to using casing in this way.In addition fuse is installed in air again, because of air
Insulation performance reason, need to stay enough safe distances between out of phase fuse, in this way can be using the equipment of fuse outside
Shell is bigger than normal.Therefore, it designs one kind and does not need wall bushing, installation is in air, exhausted for protecting circuit in oil, and in air
The problem of strong fuse of suitability becomes technical staff's urgent need to resolve can be obviously reduced in edge distance.
Summary of the invention
In order to solve the above technical problems, the technical solution used in the present invention is: a kind of compound insulation type fuse, including
Fusion tube (1) and the fusion tube fixing card (7) being arranged on fusion tube (1), it is characterised in that: the fusion tube (1) is cylindrical structure
And the upper and lower ends of the fusion tube (1) are separately connected and are provided with contact supporting (2), the inside of the contact supporting (2), which is equipped with, leads
Contact supporting (2) are stretched out in one end of electric pole (4), the conducting rod (4), and one end connects fusion tube fixing card (7) and the fusion tube is solid
Fixed card (7) is fixed with the contact (8) of fusion tube (1), and the contact supporting (2) is equipped with pedestal (3) and pedestal (3) is diagonally equipped with two
A installation screw (9) is equipped with outer cover (11) on the pedestal (3) and is covered fusion tube current-carrying part by installation screw (9),
The card slot (5) of rectangular concave inward structure is equipped on the pedestal (3) of the contact supporting (2) at the leading-out terminal of the conducting rod (4),
Sealing ring (6) are fixed with by the screw hole (10) of setting in the card slot (5).
Further, the fusion tube (1) is limiting fuse.
Further, the conducting rod (4) is equipped with taper reinforcing prop (12) on the pedestal (3) of contact supporting (2).
Further, the outer cover (11) is epoxy resin material.
The invention has the advantages that the present invention is changing contact supporting structure by the redesign to contact supporting
In the case where, it is additionally arranged card slot, fixing threaded hole, sealing ring, and be additionally arranged the structures such as epoxy resin outer cover, makes fuse more
, safe insulation facilitates installation, especially suitable for conducting rod leading-out terminal in oil-insulation medium, in other parts in air
Insulating forms, insulation distance is small in air, increases the suitability of fuse.
The additional aspect and advantage of the embodiment of the present invention will be set forth in part in the description, and will partially retouch from following
Stating becomes to recognize in obvious or practice through the invention.
Detailed description of the invention
Fig. 1 is this practical main view, and Fig. 2 is top view of the invention, and Fig. 3 is the enlarged drawing of card slot (5) of the invention,
Fig. 4 is outer cover (11) schematic diagram of the invention.
Each component label is as follows in attached drawing: 1. fusion tubes, 2. contact supportings, 3. pedestals, 4. conducting rods, 5. card slots, 6. sealings
Circle, 7. fusion tube fixing cards, 8. contacts, 9. installation screws, 10. screw holes, 11. outer covers, 12. reinforcing props.
Specific embodiment
In order to enable those skilled in the art to better understand the solution of the present invention, and make above-mentioned purpose of the invention, feature
Can be more obvious and easy to understand with advantage, the present invention is described in detail with reference to the accompanying drawing.
