Description
Technical field
The utility model relates to a kind of insulator zero value detection feeler lever.
Background technology
When power circuit overhauls, the insulator zero value detection is one of essential items for inspection, insulator zero value detection instrument commonly used at present comprises the megohmmeter that the insulator zero value detection is used feeler lever and is electrically connected with it, wherein the insulator zero value detection comprises the insulation body of rod with feeler lever, the upper end of the insulation body of rod is fixedly connected with insulation fork plate, be connected with two metal probes on the insulation fork plate, metal probe is electrically connected with the lead-in wire formation, and going between to constitute with megohmmeter is electrically connected again.In use, with supply line's outage, need a people to carry the insulator zero value detection and go up electric pole earlier, adjust the direction of the insulation body of rod with the feeler lever climbing, two metal probes are electrically contacted well with two metal ends of insulator respectively, rotate the crank of megohmmeter then, read the insulation resistance of the insulator of surveying, when insulating resistance value during greater than 300 megaohms, then insulation is good, when insulating resistance value during less than 300 megaohms, defective insulation then, the insulator that need more renew.The conventional insulators zero value detection is with the weak point of feeler lever: the length of the insulation body of rod is generally more than 2 meters, and is extremely inconvenient when the climbing electric pole, and be easy to run into other high voltage alive equipment on every side, has potential safety hazard.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to use at above-mentioned deficiency, and the higher a kind of insulator zero value detection feeler lever of security.
For solving the problems of the technologies described above, this insulator zero value detection comprises the insulation body of rod with feeler lever, and the upper end of the insulation body of rod is connected with insulation fork plate, is connected with two metal probes on the insulation fork plate, metal probe is electrically connected with the lead-in wire formation, and its design feature is: the insulation body of rod is telescopic hollow tube.
After this insulator zero value detection is designed to telescopic hollow tube with the insulation body of rod of feeler lever, the insulation body of rod just can stretch or shrink in the longitudinal direction, the hop count of hollow tube design is many more, length after the insulation body of rod shrinks is just short more, when carrying or deposit also just with regard to Vietnamese side, before pole-climbing, the body of rod that will insulate earlier compression, make the length of the insulation body of rod reach the shortest, when pole-climbing, carry very convenient like this, eliminated because of the long potential safety hazard of bringing of insulating bar body length, climb to the proper height of electric pole as the people, in the time of need measuring the insulation resistance of insulator, the insulation body of rod is stretched, make being of convenient length of the insulation body of rod after the stretching, so that make two end in contact of metal probe and insulator good, lower end with lead-in wire connects megohmmeter then, measure and get final product, very convenient, measurement finishes, and the insulation body of rod is compressed into short length, then the insulator zero value detection is got final product down from the electric pole band with feeler lever, eliminated and in the lower beam process, carried long insulator zero value detection, ensured gauger's personal safety with the potential safety hazard that feeler lever brings.
As improvement, adjust for convenience the direction of insulation fork plate, the upper end of the insulation body of rod vertically is bolted with joint pin, and the other end of joint pin pitches with insulation that plate is vertical to be spirally connected.
The gauger is when carrying out the insulator zero value detection, gauger's position generally maintains static, and that insulator has is a plurality of, and be positioned at different positions, so, when measuring, for make insulation fork plate can with different insulator position correspondences, so that the metal probe on the insulation fork plate and the metallic object at insulator two ends contacts well, vertically be bolted with joint pin in the upper end of the insulation body of rod, the other end of joint pin pitches that plate is vertical to be spirally connected with insulating, like this, insulation body of rod place straight line and insulation fork plate place plane parallel, and link together by joint pin between the insulation fork plate and the insulation body of rod, joint pin is vertical with insulation fork plate, joint pin is also vertical with the insulation body of rod, so insulation fork plate can be along 360 ° of rotations of joint pin axis, when needs are measured the insulator of diverse location, just can be by the angle between the joint pin adjustment insulation fork plate and the insulation body of rod, making insulation fork plate corresponding, contacting better, measuring faster with tested insulator direction.
As further improvement, more convenient for lead-in wire is connected with metal probe, metal probe and lead-in wire constitute electrical connection by the plug and socket that cooperatively interacts.
In sum, adopt the insulator zero value detection feeler lever of this structure, simple in structure, easy to use, and security is higher, uses when being adapted at outage detection insulator null value, use when being particluarly suitable for the insulator zero value detection of power utilization environment complexity.
