Abstract

The utility model discloses a kind of temporary ground wire bar carrying warning device, comprise acoustic-optic alarm, ground connection clamp, insulating bar and operating handle, described acoustic-optic alarm is electrically connected to described ground connection clamp, described ground connection clamp is fixedly installed on the top of described insulating bar, and described operating handle is installed on the bottom of described insulating bar.According to the utility model, and from real work situation, temporary ground wire used is at present utilized to transform.Acoustic-optic alarm is installed additional in grounding wire connector position.Utilize induced electricity principle, according to the difference of electric pressure, different warning starting voltages is set.That is, before the non-contact electrification body of earth connection, the warning device at grounding wire connector place is made to carry out sound and light alarm by induced electricity principle.Remind operating personnel's equipment live, and then shut-down operation.Thus avoid the generation of pernicious misoperation fault.

Description

Carry the temporary ground wire bar of warning device
Technical field
The utility model relates to a kind of electric power tool, particularly relates to a kind of temporary ground wire bar carrying warning device.
Background technology
In recent years, the misoperation fault of live earth connection happens occasionally in electric power system.In order to prevent the generation of the pernicious misoperation fault of live connection of ground wire, people have installed " five prevent " system in transformer station, by a series of Logic judgment and electrical interlocks and mechanical latching, serve certain effect to what prevent misoperation fault.But " five prevent " of transformer station can not manage and on-line monitoring effectively for temporary ground wire and earth point at present.Tired operating personnel, relieve and do not explain clearly in situation, easily cause the generation of the pernicious misoperation fault of live temporary ground wire.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of temporary ground wire bar carrying warning device.
The temporary ground wire bar of what the utility model provided carry warning device, comprise acoustic-optic alarm, ground connection clamp, insulating bar and operating handle, described acoustic-optic alarm is electrically connected to described ground connection clamp, described ground connection clamp is fixedly installed on the top of described insulating bar, and described operating handle is installed on the bottom of described insulating bar.
According to the utility model, and from real work situation, temporary ground wire used is at present utilized to transform.Acoustic-optic alarm is installed additional in grounding wire connector position.Utilize induced electricity principle, according to the difference of electric pressure, different warning starting voltages is set.That is, before the non-contact electrification body of earth connection, the warning device at grounding wire connector place is made to carry out sound and light alarm by induced electricity principle.Remind operating personnel's equipment live, and then shut-down operation.Thus avoid the generation of pernicious misoperation fault.
Accompanying drawing explanation
Fig. 1 shows according to the schematic diagram carrying an embodiment of the temporary ground wire bar of warning device of the present utility model.
Embodiment
Illustrate according to embodiment of the present utility model below in conjunction with accompanying drawing.
Set forth a lot of detail in the following description so that fully understand the utility model, but, the utility model can also adopt other to be different from other modes described here and implement, and therefore, the utility model is not limited to the restriction of following public specific embodiment.
Fig. 1 shows according to the schematic diagram carrying an embodiment of the temporary ground wire bar of warning device of the present utility model.
As shown in the figure, the temporary ground wire bar of what the utility model provided carry warning device, comprise acoustic-optic alarm 1, ground connection clamp 2, insulating bar 3 and operating handle 4, described acoustic-optic alarm 1 is electrically connected to described ground connection clamp 2, described ground connection clamp 2 is fixedly installed on the top of described insulating bar 3, and described operating handle 4 is installed on the bottom of described insulating bar 3.
According to the utility model, and from real work situation, temporary ground wire used is at present utilized to transform.Acoustic-optic alarm is installed additional in grounding wire connector position.Utilize induced electricity principle, according to the difference of electric pressure, different warning starting voltages is set.That is, before the non-contact electrification body of earth connection, the warning device at grounding wire connector place is made to carry out sound and light alarm by induced electricity principle.Remind operating personnel's equipment live, and then shut-down operation.Thus avoid the generation of pernicious misoperation fault.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
