Description
Technical field
The present invention relates to a kind of isolating switch, particularly relate to a kind of insulator crossarm isolating switch.
Background technology
Isolating switch is one of 10kV power circuit capital equipment, need be arranged on shaft tower with cross-arm, and the mounting means lead-in wire used at present is more, and waste material, take the vertical space of shaft tower, time-consuming during installation, result of use is poor.
Summary of the invention
The object of this invention is to provide one and save man-hour, save material, the space on shaft tower can be increased 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, lower fixed contact is designed with lower connecting terminal, lower fixed contact is also hinged with plug-in strip, 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 fixing pulling buckle.
Advantageous effect of the present invention is: due to this structure of the present invention, so use the present invention easy for installation, can reduce and connect wire, insulator and steel, can increase the space on shaft tower, result of use is good.

Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
The present invention as shown in Figure 1, 2, a kind of insulator crossarm isolating switch, comprise insulator crossarm 1, it is characterized in that: the conductor wire end of insulator crossarm 1 is fixedly connected with fixed mount 2, the left end of fixed mount 2 is fixedly connected with insulator 10, the lower end of insulator 10 is fixedly connected with lower fixed contact 8, lower fixed contact 8 is designed with lower connecting terminal 9, lower fixed contact 8 is also hinged with plug-in strip 7, the movable end of plug-in strip 5 is designed with self-locking device 5, the right-hand member of fixed mount 2 is fixedly connected with upper connecting terminal 3 and upper static contact 4, and upper static contact 4 and self-locking device 5 cooperatively interact; In the present embodiment, the movable end of described plug-in strip 7 is designed with fixing pulling buckle 6.
Insulator crossarm can fix one to three-phase conducting wire, insulator crossarm namely as insulation against ground and the phase insulation of wire, again as over the ground of the present invention or phase insulation.: install a fixed mount in the below at insulator crossarm fixing cord position additional along wire direction, fixed support and wire and upper static contact equipotential, the insulator of the left end installation of fixed mount, supports insulative when disconnecting as isolating switch between upper and lower fracture, the movable end of plug-in strip is slidably connected on lower fixed contact, rotate along wire direction, and have opening limit device, opening limit device makes plug-in strip separating brake 90
ospacing during position.During combined floodgate plug-in strip with fixedly put up 30
oangle;
The T that the present invention is applicable to 10kV and following power circuit connects, and during use, wire is fixed on the metal position of insulator crossarm, and wire is connected with upper connecting terminal, lower connecting terminal connects T link, insulating rod during operation, hooks drop-down in fixing pulling buckle sending, can complete breaking-closing operating.
