A support is arranged in the middle part of the pin-type insulator, a lower static contact of the disconnecting switch is mounted on the support, a moving contact is mounted on the lower static contact, and the lower end of the moving contact is in rotary connection with the lower static contact; an upper support is fixed on the top of the pin-type insulator, an upper static contact of the disconnecting switch is fixedly mounted on the upper support, and the upper end of the moving contact is in movable lock joint with the upper static contact; a lower binding post is fixedly connected to the lower static contact; an upper biding post is fixedly connected to the upper static contact; an opening stopper is fixedly mounted on the lower static contact; and the moving contact is equipped with an operational ring. The pin-type insulator disconnecting switch has the advantages that the pin-type insulator is used as a port and ground insulation of the disconnecting switch as well as ground insulation of leads; the upper biding post is used as both a connection terminal and a fixing lead, so that connection leads of towers are reduced; and thus, the pin-type insulator disconnecting switch is simple in installation, reduces installation difficulty, and can be installed independently.
Description
Technical field
The utility model relates to the isolated switchgear that a kind of electric power system construction of line is used, and relates in particular to a kind of pin insulator isolating switch
Background technology
Isolating switch is one of 10kV power circuit capital equipment, is arranged on cross arm of tower, goes between more, takies the vertical space of shaft tower, and the set-up time is longer, and the activity space of maintainer on shaft tower reduces relatively greatly, strengthened difficulty of construction.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of installation, reduces installation difficulty, the pin insulator isolating switch that can install separately.
For achieving the above object, the technical scheme that adopts of the utility model is:
A kind of pin insulator isolating switch, comprising pin insulator, its characteristics are: the middle part of pin insulator fixedly is designed with support, and the lower fixed contact of isolating switch is installed on support, on lower fixed contact, moving contact is installed, the lower end of moving contact and lower fixed contact are rotationally connected; The top of pin insulator fixedly is designed with upper bracket, is installed with the upper static contact of isolating switch on upper bracket, the upper end of described moving contact and upper static contact active buckle.
According to above-mentioned pin insulator isolating switch, its characteristics are: be fixedly connected with lower connecting terminal on described lower fixed contact.
According to above-mentioned pin insulator isolating switch, its characteristics are: described upper static contact is fixedly connected with upper connecting terminal.
According to above-mentioned pin insulator isolating switch, its characteristics are: be installed with the separating brake guide vane end stop on described lower fixed contact.
According to above-mentioned pin insulator isolating switch, its characteristics are: be designed with the operation ring on described moving contact.
The utility model has the advantages that: due to this structure of the utility model, isolating switch does not need independent fixedly cross-arm, and isolating switch and installation when installing pin insulator work, has saved man-hour, saves cross-arm; Middle pin insulator is namely as port and the insulation against ground of isolating switch, again as the insulation against ground of wire; Upper connecting terminal is namely as the splicing ear wire use that fixes, and subtracts to connect the connection wire that has lacked the shaft tower steel; Due to the angle of moving contact and pin insulator, so the utility model installation is simple, reduces installation difficulty, can install separately.
