Abstract
The invention discloses an outdoor load switch comprising an upper insulator, a lower insulator, a pedestal, and a supporting rod. The upper insulator and the lower insulator are disposed on the pedestal, and are provided with a switch blade. Two ends of the switch blade are provided with an arc extinguishing contact and a lower contact seat. The supporting rod is disposed on one side of the pedestal, and is provided with an insulator, which is provided with a fuse, and in addition, the fuse is slidably connected with the insulator. The end of the supporting rod is provided with a connecting arm, and the supporting rod is provided with an operating rod. Two ends of the connecting arm are respectively connected with the fuse and the supporting rod in a hinged manner, and the middle part of the connecting arm is connected with the operating rod in a hinged manner. The outdoor load switch is advantageous in that the structure is simple, and the operation is convenient; the use is safe and reliable, and the overload protection function can be provided.
Description
Technical field
The present invention relates to a kind of outdoor load switch.
Background technology
Simple arc-control device is generally housed, but it is relatively simple for structure. Figure is a kind of air pressing type high voltage load switch, and its course of work is: when separating brake, under the effect of tripping spring, main shaft turns clockwise, and by slider-crank mechanism, piston is moved up on the one hand, by gas compression; By the transmission system of two cover quadric chain compositions, main switch cutter is first opened on the other hand, then promoted arc extinguishing plug-in strip arcing contact is opened, the compressed air in cylinder is blown out electric arc by spout. On-load switch is a kind of device for switching between breaker and isolating switch, has simple arc-control device, can cut off rated load electric current and certain overload current, but can not cutting-off of short-circuit electric current. The operation principle of high voltage load switch is similar to breaker. Simple arc-control device is generally housed, but it is relatively simple for structure. Figure is a kind of air pressing type high voltage load switch, and its course of work is: when separating brake, under the effect of tripping spring, main shaft turns clockwise, and by slider-crank mechanism, piston is moved up on the one hand, by gas compression; By the transmission system of two cover quadric chain compositions, main switch cutter is first opened on the other hand, then promoted arc extinguishing plug-in strip arcing contact is opened, the compressed air in cylinder is blown out electric arc by spout.
Current existing on-load switch complex structure, inconvenient operation, does not possess overload protection function when use.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in structure, easy to operate, safe and reliable, has the outdoor load switch of overload protection function.
For addressing the above problem, the present invention adopts following technical scheme: a kind of outdoor load switch, comprise insulator, lower insulator, base and pole, described upper insulator and lower insulator are located on base, on described upper insulator and lower insulator, plug-in strip is installed, described plug-in strip two ends are provided with arcing contact and lower touch base, described pole is located at base one side, on described pole, insulator is installed, on described insulator, be provided with fuse, described fuse and insulator are slidably connected, described pole end is located at and is provided with Abduction arm, on described pole, be provided with action bars, described Abduction arm two ends are hinged with fuse and pole respectively, described Abduction arm middle part is hinged with action bars.
As preferably, below described plug-in strip, be provided with insulated tension pole, keep insulation effect good.
As preferably, described plug-in strip is fixedly connected with base by insulated tension pole, and holding structure is reliable and stable.
As preferably, described fuse front end is provided with contact, conveniently installs.
As preferably, described contact and lower touch base are electrically connected, and keep energising smooth and easy.
Beneficial effect of the present invention is: the upper insulator of setting, lower insulator keep plug-in strip easy for installation; the action bars arranging can regulate Abduction arm position; fuse is moved on insulator, facilitate the contact of fuse be connected or disconnect with lower touch base, easy to operate; safe and reliable; fuse can fuse in the time of overload, effectively protects outdoor load switch, when arcing contact can keep operating; eliminate electric arc, keep using safety.
