Abstract
The utility model discloses a kind of intermediate Disjunction type fuse switches, including upper terminals（1）, upper static contact（2）, upper moving contact（3）, pipe cap（4）, operation ring（5）, fusion tube（6）, fuse（7）, lower moving contact（8）, lower static contact（9）, lower terminals（10）, insulating support（11）, metal mounting plate（12）And insulator（13）；Wherein insulating support（11）Insulator（13）Be divided into two sections, respectively with metal mounting plate（12）Connection；Metal mounting plate（12）One end and insulating support（11）Connection, other end ground connection.Work as insulating support（11）Insulation resistance standard requirement is not achieved, ground short circuit signal will be generated, whole system is made to operate a switch power-off.
Description
Technical field
The utility model is related to fuse fields, more particularly, to a kind of intermediate Disjunction type fuse switch.
Background technology
Fuse switch is 10kV distribution lines branch line and a kind of most common protective switch of the short circuit of distribution transformer,
It has the characteristics that economical, easy to operate, adaptation outdoor environment is strong, is widely used in 10kV distribution lines and distribution transformer
Device primary side is used as protecting and carry out equipment throwing, cut operation.
But power supply station's employee's upper stage has occurred in actual application and repairs the ordinary accident got an electric shock and died, it is real
It tests result and confirms B phase fuse switch insulating support internal breakdowns.It can thus be appreciated that when rack works, it is molten in part drop type
Disconnected device is in the case where fuse tube has pulled open, if insulating support causes to insulate by the lightning stroke reasons such as internal breakdown or aging
Holder is connected, and staff is grounded without electrical verification during repairing, and direct upper stage work will accidentally touch charging equipment and cause
The person gets an electric shock.
Invention content
To realize the above goal of the invention, the technical solution adopted is that：A kind of intermediate Disjunction type fuse switch, including it is upper
Terminals 1, upper static contact 2, upper moving contact 3, pipe cap 4, operation ring 5, fusion tube 6, fuse 7, lower moving contact 8, lower static contact 9, under
The insulator 13 of terminals 10, insulating support 11, metal mounting plate 12 and insulator 13, wherein insulating support 11 is divided into two sections,
It is connect respectively with metal mounting plate 12；12 one end of metal mounting plate is connect with insulating support 11, other end ground connection.
In the above scheme, the insulator 13 of the insulating support 11 of fuse switch is divided into two sections, uses metal mounting plate
12 connect two sections of insulators 13.Metal mounting plate 12 plays the role of fixed mounting plate, meanwhile, by metal mounting plate
12 ground connection, when the insulator 13 in insulating support 11 is punctured or aging leads to be not achieved the standard requirement of insulation resistance by thunder and lightning,
Metal mounting plate 12 and insulator 13 are connected, and generate ground short circuit signal, and whole system is operated a switch power-off.
Compared with prior art, the utility model has the beneficial effects that：
1）It is suitble to the installation of various racks and distribution branch line；
2）Fixed metal plate is grounded, and increases operational security；
3）The structure of existing 10KV fuse switches is improved, design and develop it is at low cost, technology be easy replicate push away
Extensively.
