Abstract
An alarm-type grounding wire comprises a circular pipe handle of an insulating material. An upper end of the circular pipe handle of the insulating material is connected with a ground clamp. The ground clamp is provided with a terminal. A lower end nozzle of the insulating-material circular pipe is provided with an insulating-material pipe plug. One end of the pipe plug is connected with an electroscope chip, wherein the end is in the insulating-material circular pipe. In the insulating-material circular pipe, an input terminal of the electroscope chip is connected with the ground clamp through a lead. A pipe wall of the insulating-material circular pipe is provided with a small hole, wherein the pipe wall is the place where the electroscope chip is located. According to the utility model, the electroscope chip is arranged. In a period when the tested line is not power on and before the grounding wire is installed, by using the grounding wire of the utility model, a situation that there is induced electricity on the line after the power is off or an accidental power transmission phenomenon can be safely discovered. The usage is safe.
Description
Technical field
The utility model relates to a kind of alarm of line power ground, particularly a kind of earth connection.
Background technology
Power transmission system will break off the power supply in the circuit when maintenance, and by operational procedure, the power supply in the circuit will carry out electrical verification with electroscope after breaking off; Confirm that circuit has a power failure; If circuit cuts off the power supply really, use earth connection line-to-ground again, could implement line maintenance work.Electroscope has insulated handle, and there is housing the insulated handle upper end, is connected with contact on the housing, and the electroscope chip is arranged in the housing, and electroscope circuit and audible-visual annunciator are arranged on the electroscope chip, and the contact on the housing links to each other with the input of electroscope chip.During electrical verification, with the electric wire of contact touching circuit, if circuit has electricity, the audible-visual annunciator of electroscope chip can be reported to the police, if circuit does not have electricity, the audible-visual annunciator of electroscope chip can not reported to the police.Earth connection has the pipe handle of insulating material, and insulating material pipe handle upper end is connected with ground clamp, and ground wire accompanies terminals.During ground connection, be connected in the ground clamp terminals on the ground wire with lead earlier, hand-held again insulating material pipe hadle ground clamp is clamped on the electric wire that has cut off the power supply.In the prior art; Earth connection does not have the electroscope function; Though do not have with electroscope check circuit in maintenance circuit outage back; But checking circuit not have energising and in a period of time between the installing earth connection, the phenomenon that outage back circuit has induced electricity or send electricity is unexpectedly taking place sometimes, if at this moment security incident can take place ground connection.Above-mentioned earth connection is not very safe sometimes.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned deficiency, to propose a kind of alarm type earth connection safe in utilization.
The utility model is realized with following method.
The alarm type earth connection; The pipe handle that insulating material is arranged, the upper end of insulating material pipe handle is connected with ground clamp, and ground wire accompanies terminals; The lower end mouth of pipe of insulating material pipe has the mouth of pipe plug of insulating material; The end of mouth of pipe plug in the insulating material pipe is connected with the electroscope chip, and in the insulating material pipe, be connected with lead between the input of the electroscope chip of electroscope chip and the ground clamp, the tube wall of electroscope chip place, insulating material pipe has aperture.
During use, be connected in the ground clamp terminals on the ground wire earlier the electric wire that hand-held again insulating material pipe hadle ground clamp touching has been cut off the power supply with lead; If circuit has; The audible-visual annunciator of electroscope chip can be reported to the police, and the electrician can hear and see the acousto-optic of warning through the aperture of insulating material tube wall, if circuit does not have; The audible-visual annunciator of electroscope chip can not reported to the police, and the electrician can be clamped in ground clamp on the electric wire that has cut off the power supply safely.
The utility model has the electroscope chip, is checking circuit not have energising and within installing a period of time between the earth connection, even when outage back circuit has induced electricity or send the phenomenon of electricity unexpectedly, can find safely with the utility model, uses very safe.
Below in conjunction with accompanying drawing, the utility model is done explanation further.
Description of drawings
Fig. 1 cuts open sketch map according to the master office of looking of a kind of alarm type earth connection of the invention scheme proposition of the utility model.
Embodiment
Among Fig. 1, the alarm type earth connection has the pipe handle 1 of insulating material; The upper end of insulating material pipe handle is connected with ground clamp 2; Ground wire accompanies terminals 3, and the lower end mouth of pipe of insulating material pipe has the mouth of pipe plug 4 of insulating material, and the end of mouth of pipe plug in the insulating material pipe is connected with electroscope chip 5; In the insulating material pipe, be connected with lead 7 between the input 6 of the electroscope chip of electroscope chip and the ground clamp, the tube wall of electroscope chip place, insulating material pipe has aperture 8.
Claims (1)
