Abstract
The invention relates to a pin insulator disconnecting switch which comprises a pin insulator, wherein a bracket is arranged at the middle part; a lower fixed contact of the disconnecting switch is mounted on the bracket; a moving contact is mounted on the lower fixed contact; the lower fixed contact is rotationally connected with the lower end of the moving contact; an upper bracket is fixedly designed at the top end of the pin insulator; an upper fixed contact of the disconnecting switch is fixedly mounted on the upper bracket; the upper fixed contact is movably buckled with the upper end of the moving contact; lower connecting terminals are fixedly connected onto the lower fixed contact; an upper connecting terminal is fixedly connected with the upper fixed contact; a brake separating limiting stopper is fixedly mounted on the lower fixed contact; and an operating ring is designed on the moving contact. The pin insulator disconnecting switch has the advantages that the pin insulator is not only taken as a port and a ground insulation of the disconnecting switch, but also taken as the ground insulation of conducting wires; the upper connecting terminal is taken as a connector to fix the conducting wires; the connecting wires of the pole-tower steel are reduced; so that the mounting is simple; the mounting difficulty is reduced; and the switch can be mounted independently.
Description
Technical field
The present invention relates to the isolated switchgear that a kind of electric power system construction of line is used, relate in particular to a kind of pin insulator isolating switch
Background technology
Isolating switch is one of 10kV power circuit capital equipment, is installed on the shaft tower cross-arm, and it is more to go between, and 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 to the purpose of this invention 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 solution adopted in the present invention is:
A kind of pin insulator isolating switch, comprising pin insulator, its characteristics are: the fixing design in the middle part of pin insulator has support, and the following fixed contact of isolating switch is installed on the support, on the following fixed contact moving contact is installed, the lower end of moving contact is rotationally connected with following fixed contact; The fixing design in the top of pin insulator has upper bracket, is installed with the upper static contact of isolating switch on the 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 the fixed contact under described.
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 the fixed contact under described.
According to above-mentioned pin insulator isolating switch, its characteristics are: design has the operation ring on the described moving contact.
Advantage of the present invention is: because this structure of the present invention, 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; In pin insulator namely as port and the insulation against ground of isolating switch, again as the insulation against ground of lead; Upper connecting terminal is namely as the splicing ear lead usefulness that fixes, and subtracts to connect the connection lead that has lacked the shaft tower steel; Because the angle of moving contact and pin insulator, so the present invention installs simply, and the reduction installation difficulty can be installed separately.
