Description
Technical field
The present invention relates to a kind of isolating switch, relate in particular to a kind of insulator crossarm isolating switch.
Background technology
Isolating switch is one of 10kV power circuit capital equipment, needs to be installed on the shaft tower with cross-arm, and the mounting means lead-in wire that uses at present is more, wastes material, takies the vertical space of shaft tower, and time-consuming during installation, result of use is poor.
Summary of the invention
The purpose of this invention is to provide a kind of saving man-hour, save material, can increase space on the shaft tower and the insulator crossarm isolating switch of handled easily.
For achieving the above object, the technical solution used in the present invention is: a kind of insulator crossarm isolating switch, comprise insulator crossarm, it is characterized in that: the conductor wire end of insulator crossarm is fixedly connected with fixed mount, the left end of fixed mount is fixedly connected with insulator, the lower end of insulator is fixedly connected with lower fixed contact, be designed with lower connecting terminal on the lower fixed contact, also be hinged with plug-in strip on the lower fixed contact, the movable end of plug-in strip is designed with self-locking device, the right-hand member of fixed mount is fixedly connected with upper connecting terminal and upper static contact, and upper static contact and self-locking device cooperatively interact.
In this structure, the movable end of described plug-in strip is designed with fixedly pulling buckle.
Advantageous effect of the present invention is: because this structure of the present invention so use the present invention easy for installation, can reduce connection wire, insulator and steel, can increase the space on the shaft tower, result of use is good.
