Description
Technical field
The utility model relates to the instrument that a kind of hot line job is insulated and detected, and particularly a kind of hot line job insulation detects special-purpose rapier.
Background technology
In these years, along with the continuous development of electrical network, hot line job can not cause plurality of advantages such as the user has a power failure, can power more because of it, is promoted just gradually and uses.Can hot line job be carried out safely and effectively, depends on to a great extent whether the configuration of some instruments is qualified safely.And the more on-the-spot insulating tools that will use of hot line job, the quality of its dielectric strength also directly influences entire job.Clear and definite regulation in " electric power safety working regulation " 10.12.2.5 bar that State Grid Corporation of China issues: " before live line tool used, scrutiny was confirmed not damage, is made moist, distortion, malfunctioning, otherwise banned use of.And use 2500KV and above insulation resistance meter or insulation tester to carry out graded insulation and detect (the wide 2cm of electrode, the wide 2cm of interpolar) resistance and should be not less than 700M Ω. ".Before each operation, all will carry out sectionalization test to insulating tool, make such hard and fast rule, also be for the effective insulated lengths that guarantees insulating tool reaches requirement, thereby guarantee hot line job personnel's safety.
At present, most prefecture-level electric company has all disposed special segmentation detection insulation tester, because this type of segmentation detector costs an arm and a leg, some electric companies are also arranged because the shortage of capital is not equipped with, and as the electric company that is equipped with the special isolation detector, owing to be equipped with negligible amounts, the operation distributed points is more, especially during line live-line work, the contradiction that can't in time detect is very outstanding, with the operation of a 220KV electric pressure is example, if will detect a long insulation ropes of 30 meters, the insulation rope ladder of a 20-30 rice, one 3 meters insulating bar, and this only is the instrument of a setting, and is during for the multiple spot operation of the same line road, just more unable to do what one wishes by a dedicated tester.Investigation finds that the staff of some electric company follows the line of least resistance, and just employed insulating tool is examined less or is not examined, and the direct result of doing has like this constituted serious threat to safety beyond doubt.
At present, the portable electronic multimeter is widely used in the electrical production because of the characteristics of its low cost and availability, almost each production teams and groups all is equipped with, and its range maximum can be used for measuring the insulating bodies greater than 700M Ω in theory in G Ω.; the general character of these tables is that the electrode of its probe pen that is used to measure is the pin type metallic object that two diameters are 1mm; width is not the battery lead plate of 2 cm; do not meet insulating tool is implemented the rigid requirement that segmentation detects; the electrode of its probe pen is again movable, and the anode-cathode distance of 2cm can not be guaranteed in implementation process.
Summary of the invention
The utility model provides a kind of special-purpose rapier rational in infrastructure, simple to operate in order to overcome the defective of existing hot line job insulation testing tool, cooperates the existing portable multimeter of electronics to operate, and can finish the preceding insulation testing of hot line job.Both save the purchase cost of special-purpose graded insulation detector, utilized existing resource again, thereby guaranteed hot line job safety.
The technical solution adopted in the utility model is as follows:
The hot line job insulation detects special-purpose rapier and comprises two metal electrode boards and an insulation rapier fixator, described metal electrode board upper end is curved, the lower end is connected to metallic plug, metallic plug inserts the insulating sheath jack of described insulation rapier fixator, this jack lower end connects test lead, test lead stretches out and connects two Insulation test table plugs, this plug connection Insulation test table from insulation rapier fixator tail end.
There is last lower arcuate surface described metal electrode board upper end, long 3-5cm, and wide 2cm, thick 1-5mm adopts iron, aluminium or other conductive material to make, and need guarantee that plate width meets the rules requirement of 2cm.
Described two metal electrodes are a plane in use, and anode-cathode distance keeps 2cm, the requirement of assurance match operation rules.
Described insulation rapier fixator below is provided with handle.
Described Insulation test table can be selected portable electronic multimeter or insulation resistance meter for use.
Utilizing the hot line job insulation to detect special-purpose rapier detects institute's survey insulating tool, special-purpose rapier can be inserted portable electronic multimeter or insulation resistance meter, hold this insulation and detect Square handle under the special-purpose rapier fixator, the arc female parts of metal electrode board and tested instrument are closely contacted and slide forward, reading on the observation watch meter is until the testing of finishing whole insulating tool.
This hot line job insulation detects special-purpose rapier, match with general, inexpensive portable multimeter or insulation resistance meter etc., requisite insulation testing when finishing hot line job, can fundamentally solve the difficulty that special isolation segmentation detector deficiency causes, and because the special-purpose rapier cost of this kind insulation detection is lower, be easy to promote the use of, suit especially to use when multiple spot is carried out hot line job on the circuit of different electric pressures.
