Abstract
The invention discloses a probe rod for insulator detection. The technical scheme is that the probe rod for insulator detection comprises an insulation rod body, wherein an insulation forked plate is connected at the upper end of the insulation rod body, two metal probes are connected onto the insulation forked plate and electrically connected with a lead wire, and the insulation rod body is a telescopic hollow pipe. A connection column is vertically screwed at the upper end of the insulation rod body, and the other end of the connection column is vertically connected with the insulation forked plate in screwed mode. The metal probes are electrically connected with the lead wire through a plug and a socket which are matched. The probe rod for insulator detection has the advantages of being simple in structure, convenient to use, high in safety, suitable for being used when insulator value is zero in power failure detection and especially applicable to insulator zero value detection in complex electricity utilization environment.
Description
Technical field:
The present invention designs the power circuit monitoring tool, and particularly a kind of insulator detects and uses feeler lever.
Background technology:
When Electric Power Line Overhaul, the insulator zero value detection is one of essential items for inspection, insulator zero value detection instrument commonly used comprises the megohmmeter that the insulator zero value detection is used feeler lever and is electrically connected with it at present, 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 consist of with megohmmeter is electrically connected again.In use, with supply line's outage, need a people to carry the insulator zero value detection and climb upper electric pole with feeler lever first, adjust the direction of the insulation body of rod, two metal probes are electrically contacted well with two metal ends of insulator respectively, then rotate the crank of megohmmeter, read the insulation resistance of the insulator of surveying, when insulating resistance value during greater than 300 megaohm, then insulation is good, when insulating resistance value during less than 300 megaohm, defective insulation then, the insulator that need to 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.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of simple in structure, easy to use for above-mentioned deficiency, and the higher a kind of insulator detection feeler lever of security.
Technical scheme of the present invention is, a kind of insulator detects and uses feeler lever, and it comprises the insulation body of rod, the upper end of the insulation body of rod is 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, it is characterized in that: the insulation body of rod is telescopic hollow tube.The upper end of the described insulation body of rod vertically is bolted with joint pin, and plate is vertical is spirally connected for the other end of joint pin and insulation fork.Described metal probe and lead-in wire consist of electrical connection by the plug and socket that cooperatively interacts.
Beneficial effect of the present invention: adopt the insulator of this structure to detect and use feeler lever, 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.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A cut-open view of Fig. 1
Embodiment:
This insulator detects with feeler lever and comprises the insulation body of rod 1, the insulation body of rod 1 is designed to compressible hollow tube, in the present embodiment, three sections hollow tubes that the insulation body of rod 1 is designed to connect together successively, the upper end of the insulation body of rod 1 is provided with a thread segment, tightened joint pin 4 on the thread segment, joint pin 4 is vertical with the insulation body of rod 1, the other end of joint pin 4 is provided with thread segment, be vertically installed with insulation fork plate 2 on this thread segment, insulation fork plate 2 is fastened on the end of joint pin 4 by wing nut 9, two ends of insulation fork plate 2 are fastened with two metal probes 3 by bolt and wing nut 9, and metal probe 3 is electrically connected with lead-in wire 5 formations, for the convenience that connects, the fastening end of metal probe 3 also is fastened with socket 7 by above-mentioned bolt and wing nut 9, and the upper end of lead-in wire 5 is electrically connected with the plug 6 that cooperates with socket 7; In use, first the insulation body of rod 1 of this insulator zero value detection with feeler lever compressed, make the insulator zero value detection as far as possible little with the shared space of feeler lever, so both can be easy to carry, can prevent that also mistake is bumped other high voltage alive equipments in climbing electric pole process, improve the safety coefficient when carrying, climbing is behind electric pole top, according to the operator present position and surveyed between the insulator distance to the insulation body of rod 1 stretch, make the insulator of surveying insulator zero value detection touching within the scope with feeler lever, and according to the angle between the insulation of the position relationship adjustment between survey insulator and operator fork plate 2 and the insulation body of rod 1, make the operator stretch out the insulator zero value detection to the survey insulator when using feeler lever, insulation fork plate 2 just can be over against tested insulator, like this, after the direction of adjusting two metal probes 3, just can well metal probe 3 be against on the sheet metal at two ends of tested insulator, thereby metal probe 3 and the sheet metal at insulator two ends are electrically contacted well, then will go between 5 lower end and megohmmeter connects the insulation resistance that can Quick Measuring gets tested insulator, save Measuring Time, improved work efficiency; Measure complete after, the insulator zero value detection is climbed down electric pole again with after the feeler lever compression, make the gauger also very safe in the process of lower beam; When overhauling complete storage, insulation fork plate 2 can be pulled down with feeler lever from the insulator zero value detection, reduced to take up room.
The invention provides a kind of thinking and method of copper core copper sheath mineral insulated cable; method and the approach of this technical scheme of specific implementation are a lot; the above only is preferred implementation of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
