Abstract
The utility model discloses an isolating switch with an earthing function, comprising a switch main body (1). A lower bottom frame (2) of the switch main body (1) is provided with a switch handle (3) which is connected with the switch main body (1) by a handle rotating shaft (4); and the lower bottom frame (2) of the switch main body (1) is provided with an earthing switch (8) which is arranged on the lower bottom frame (2) by an earthing switch rotating shaft (9); the earthing switch (8) is fixed on the earthing switch rotating shaft (9) which is fixed with an earthing crank (10); the handle rotating shaft (4) is fixed with a connecting rod crank (11); and a connecting rod (12) is connected between the earthing crank (10) and the connecting rod crank (11). For the isolating switch with the earthing function, the contact switch can be turned on or off by disconnecting and connecting the switch handle, without operating the earthing device manually.
Description
Technical field
The utility model relates to field of switches, is a kind of isolating switch of outdoor high-voltage band ground connection specifically.
Background technology
Isolating switch generally is used for the outdoor high-voltage circuit, the isolating switch of prior art generally comprises switch main body, on the below underframe of described switch main body switch knob is installed, described switch knob is connected with switch main body by arm pivot post, be fixed with the pull bar connecting lever on the described arm pivot post, be fixedly connected with insulated tension pole on the described pull bar connecting lever, the top of described insulated tension pole is connected with contact knife, and the other end and the switch main body of described contact knife are rotatably connected.During use, apply upwards or power down, just can drive insulated tension pole and move up and down by a end at switch knob, thus the opening and closing of realization contact knife.
In the use of isolating switch, when contact knife disconnects, but the electric weight that switch inside also has, and electric weight also might reverse flow go into, if this moment, human body went touching to get an electric shock, therefore after contact knife disconnects, often need switch ground connection, with the electric weight of release-push inside.Prior art generally is after contact knife disconnection back links to each other the three-phase contact knife with plain conductor, to connect earth connection again and solve the problems referred to above, and is because outdoor disconnector generally all is installed in the higher position, therefore with said method both inconvenience, also dangerous.
The utility model content
The technical problems to be solved in the utility model is that a kind of isolating switch of the band ground connection that can use safely is provided.
Technical solution of the present utility model is, a kind of isolating switch of band ground connection of following structure is provided, comprise switch main body, on the below underframe of described switch main body switch knob is installed, described switch knob is connected with switch main body by arm pivot post, is fixed with the pull bar connecting lever on the described arm pivot post, is fixedly connected with insulated tension pole on the described pull bar connecting lever, the top of described insulated tension pole is connected with contact knife, and the other end and the switch main body of described contact knife are rotatably connected.
On the below underframe of described switch main body the ground connection cutter is installed, described ground connection cutter is installed on the underframe by ground connection swivel axle, the ground connection cutter is fixed on the ground connection swivel axle, be fixed with the ground connection connecting lever on the described ground connection swivel axle, be fixed with the connecting rod connecting lever on the described arm pivot post, be connected with connecting rod between described ground connection connecting lever and the connecting rod connecting lever.
Adopt above structure, the utility model compared with prior art has the following advantages: adopt the utility model structure, when contact knife is opened under the driving of switch knob, the connecting rod connecting lever is along with arm pivot post rotates, thereby drive ground connection swivel axle by connecting rod, ground connection swivel axle rotates counterclockwise, and the ground connection cutter is contacted with contact, realize ground connection, and need not manually to handle earthing device.
As improvement, on arm pivot post, also be fixed with the stage clip connecting lever, and on underframe, be provided with a spring, described stage clip connecting lever pressing spring.Like this, when ground connection, in the process of operating switch handle, can be subjected to the certain resistance of spring, when switch knob turns over certain angle, the resistance of this rear spring becomes power, because the effect of spring can not pulled on or be unclamped easily, has guaranteed the fail safe of operation more.
