Abstract
The invention discloses an alarm type earthing wire which is provided with a circular tubular handle made of insulating material; an earth clamp is arranged at the upper end of the circular tubular handle made of insulating material; an earthing terminal is arranged on the earth clamp; a tube plug made of insulating material is arranged at the mouth of the lower end of the insulated circular tube of the circular tubular handle; an electroscope chip is connected at one end of the tube plug inside the insulated circular tube; conducting wires are connected between the input terminal of the electroscope chip and the earth clamp inside the insulated circular tube; and small holes are arranged in the wall of the insulated circular tube at the place of the electroscope chip. The alarm type earthing wire is provided with the electroscope chip, so between the time after the power line is detected to be out of power and the time before the power line is grounded, even if the power line produces induced electricity or is accidentally powered on, the alarm type earthing wire can safely find out . Therefore, the alarm type earthing wire is safe to use.
Description
Technical field
The present invention 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 electricity and between installing ground 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 objective of the invention is in order to overcome above-mentioned deficiency, propose a kind of alarm type earth connection safe in utilization.
The present invention realizes with following method.
The alarm type earth connection has the pipe handle of insulating material; The upper end of insulating material pipe handle is connected with ground clamp; Ground wire accompanies terminals, and the lower end mouth of pipe of insulating material pipe has the mouth of pipe plug of insulating material, and the end of mouth of pipe plug in the insulating material pipe is connected with the electroscope chip; 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 present invention has the electroscope chip, but checking circuit not have electricity and between installing ground connection, even cut off the power supply when afterwards circuit has induced electricity or send the phenomenon of electricity unexpectedly, can finding safely with the present invention, uses very safe.
Below in conjunction with accompanying drawing, the present invention 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 invention scheme proposition of the present invention.
Embodiment
Among Fig. 1; The alarm type earth connection has the pipe handle 1 of insulating material, and the upper end of insulating material pipe handle is connected with ground clamp 2, and ground wire accompanies terminals 3; The lower end mouth of pipe of insulating material pipe has the mouth of pipe plug 4 of insulating material; The end of mouth of pipe plug in the insulating material pipe is connected with electroscope chip 5, and 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)
1. an alarm type earth connection has the pipe handle of insulating material; The upper end of insulating material pipe handle is connected with ground clamp; Ground wire accompanies terminals, it is characterized in that: the lower end mouth of pipe of insulating material pipe has the mouth of pipe plug of insulating material, and the end of mouth of pipe plug in the insulating material pipe is connected with the electroscope chip; 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.
