Abstract
The utility model relates to a measurement auxiliary operating platform with an insulation megger, which comprises an insulating base plate, an insulating reel and the insulation megger. A megger binding post, a grounding binding post, a reel binding post and a switch are arranged on the insulating base plate. The switch is provided with a normally open contact and a normally closed contact, the normally open contact is connected with the megger binding post, and the normally closed contact is connected with the grounding binding post. The insulation megger is provided with a megger grounding wire and is also provided with a terminal connected with the megger binding post. A measurement outgoing wire is arranged on the insulating reel. One end of the measurement outgoing wire is connected with the insulating reel binding post. The measurement auxiliary operating platform with the insulation megger has the advantages that the phenomenon that in the process of measuring the insulation resistance, a circuit possibly has a residual voltage and reversely transmitted power to cause electric shock damage to personnel is avoided; the working efficiency of measuring the resistance value is improved; the power failure time is shortened; the working place is not limited; and the potential safety hazard generated when the personnel carries out measuring work is reduced.
Description
Technical field
The utility model relates to a kind of operating platform, relates to a kind of insulation megger specifically and measures the non-productive operation platform.
Background technology
During existing line insulation resistance measurement and since circuit survey lead-in wire length, unrest, difficult and the earth separate and influence measured value, cause single-phase earthing judged by accident, increased the workload of power off time and trouble-shooting point greatly.Factory of a few family or several unit or several residential block are all arranged on every 10kV circuit, and the power failure of per minute all causes the loss of huge economic benefit, because there is cold standby state in circuit, has induced electricity on the circuit, also exists and send electricity possibly threaten personal safety.
The utility model content
The technical matters that the utility model will solve is to have solved the problem that the measured value that runs in the line resistance measurement is inaccurate and threaten personal safety.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: a kind of insulation megger is measured the non-productive operation platform, comprises insulating base, insulation winder and insulation megger, and said insulating base is provided with megger binding post, ground connection binding post, winder binding post and switch; Said winder binding post links to each other with switch; Said switch is provided with normal opened contact and normally closed contact, and said normal opened contact links to each other with the megger binding post, and said normally closed contact links to each other with the ground connection binding post; Said insulation megger is provided with the megger ground wire; Said insulation megger also is provided with the terminals that link to each other with the megger binding post, and said insulation winder is provided with the measurement extension line, and said measurement extension line one end links to each other with the winder binding post.
Preferably, also comprise link rod, the said measurement extension line other end is provided with clip; Said clip places on the link rod, guarantees extension line face non-contiguously, and measured value is not affected; The not direct contact measurement extension line of personnel has ensured personal safety, and said clip also can be the connector that other extension lines of being convenient to connect connect; Said be clipped in both economical, reliable.
Preferably, said switch is a push-button switch, and said switch also can be slide switch or other switches, and the utility model is a push-button switch, is convenient to install.
Preferably, said megger binding post limit is provided with first nameplate, and ground connection binding post limit is provided with second nameplate, and winder binding post limit is provided with the 3rd nameplate, has guaranteed that like this instrument normally connects.
In sum; The advantage of the utility model is: when avoiding the line insulation resistance measurement; Possibly there is residual voltage in circuit and send the electricity personnel that cause the injury of getting an electric shock, and improves the resistance measurement work efficiency, the minimizing power off time; The work place is unrestricted, the potential safety hazard that has existed when having reduced personnel's surveying work.
