Abstract
The utility model relates to a sensing ground wire used in the overhaul and maintenance of power equipment, which belongs to the technical field of power equipment and comprises a ground wire and a wire clamp for connecting with a device to be grounded. A clamping opening formed by a pair of elastic contacting sheets is arranged inside the wire clamp. At least one grounding and sensing device is arranged between elastic contacting sheets and a substrate of the wire clamp. The grounding and sensing device comprises a position switch, and the transformation of the elastic contacting sheets can drive the position switch to change between the states of opening and closing. The position switch is arranged in a wireless signal transmitting circuit in a connecting mode. After the structure is adopted, the grounding and sensing device is arranged on the wire clamp and can continuously transmit wireless signals when the ground wire is connected, thereby enabling operators to obtain prompts through a signal receiving device so as to know timely if the ground wire is connected to circuits, effectively avoiding damage of equipment and personal injury and death, and facilitating centralized management of a plurality of ground wires.
Description
Technical field
The utility model relates to a kind of sensor-type earth connection that uses in electric power apparatus examination is safeguarded, belong to electrical equipment technical field.
Background technology
In work such as power equipment and line maintenance, usually need to articulate various earth connections and overhaul, finish when work such as maintenance, send the electricity before must remove the earth connection of waiting to send on electric loop (at interval) and the associated devices fully.But earth connection quantity is more, it is pressed for time, particularly when night and field work, because operating personnel's inadvertent forgets to tear open certain winding ground wire, cause switching on earth wire, and then the accident of damage equipment or loss of life or personal injury happens occasionally articulating.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly can detect earth connection dismounting fully, effectively prevents device damage or causes the sensor-type earth connection of the accident of loss of life or personal injury.
In order to solve the problems of the technologies described above, sensor-type earth connection of the present utility model comprises earth connection and is used for and the wire clamp for the treatment of that grounding apparatus is connected, the wire clamp inboard is provided with the folder mouth that is made of a pair of elastic contact blade, is provided with at least one ground connection sensing device between the matrix of elastic contact blade and wire clamp; Described ground connection sensing device includes a position switch, but deciliter state variation of the distortion activation point switch of described elastic contact blade; Described position switch is connected in the wireless signal transmission circuit.
Described elastic contact blade is connected with the movable contact spring of position switch by a bolster;
Described bolster comprises a compression spring.
After adopting such structure, owing to be arranged on the ground connection sensing device be set on the wire clamp, when being articulated, earth connection can continue to send wireless signal, make operating personnel obtain prompting by signal receiving device, whether in time grasp earth connection articulates on the line, can effectively prevent the generation of device damage and personal injury injures and deaths, also be convenient to a plurality of earth connections are managed concentratedly.
