Abstract
The utility model relates to a kind of pincerlike current measuring instrument of rod-type used for electric system Road test in winter professional site work, comprise probe, insulating bar, electronic current instrument, it is characterized in that described probe a kind ofly to be popped one's head in as insulation sheath " U " type magnet with elastomeric material, outside described electronic current instrument independence insulating bar, be connected with bar by insulated conductor.The utility model is used for the Road test operation in winter, because electronic current instrument is independent of outside insulating bar, relative flexible during use, avoid over the electronic current instrument display screen that occurs in some measurement situation or the generation of inconvenient reading phenomenon that causes of instrument and survey crew hypertelorism down., because probe external insulation main material is rubber, the reliability that breakage improves safety in production can not be there is under the environment that temperature is extremely low in the pincerlike current measuring instrument of rod-type simultaneously.
Description
Technical field
The utility model relates to a kind of survey instrument, particularly relates to a kind of pincerlike current measuring instrument of rod-type used for electric system Road test in winter professional site work.
Background technology
The work all will carried out when Road test is annual peak of power consumption in winter, the main tool of test is the pincerlike current measuring instrument of rod-type, and it is mainly divided into 3 parts, probe, insulating bar, electronic current instrument.Only need clamp wire to be measured with probe during measurement and by electronic current instrument reading, step on bar without the need to survey crew and carry out aerological measurement work.But along with the transition in epoch, the increase of electric pole radix, power consumption, this pincerlike current measuring instrument has been difficult to meet nowadays large batch of Road test requirement.The probe of the pincerlike current measuring instrument now used is one and " U " type magnet by plastic wraps, when carrying out Road test in the winter time, because temperature is very low, plastics meet that cold meeting is hardening to become fragile, when measuring, probe is difficult to avoid needing and conductive contact, this often causes the plastic peel of probe to be subject to breakage and magnet is outside exposed, and then electric shock accidents easily occurs, can not move because electronic current instrument is fixed on the afterbody measuring insulating bar simultaneously, when staff measures load, equipment under test position is higher, the position of staff's standing, which is away from equipment under test, insulating bar often will be stretched adjustment by staff, probe is allowed to clamp wire, the end being fixed on insulating bar due to electronic current instrument can not move, this causes electronic current instrument along with stretching of insulating bar away from survey crew, make measurement operating personnel cannot observe directly display screen on electronic current instrument, cause inconvenience during read-record, hommization not in use, and then efficiency is measured in impact.This just needs a kind of new-type, safe and reliable and facilitate the pincerlike current measuring instrument of the rod-type of reading numerical values to overcome the above problems.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art to improve, pincerlike for original plain bar type current measuring instrument (hereinafter referred to as " plain type ") is transformed, make probing shell not temperature influence and Reusability and damaged, and the position of electronic current instrument is no longer fixed on the single position of insulating bar, when solving Road test in winter by improved measuring instrument probe easily occur position that is damaged and electronic current instrument fix, cannot flexible mobile problem, improve Measurement reliability and convenience.
The technical scheme of this measuring instrument is as follows:
The pincerlike current measuring instrument of rod-type, comprise probe, insulating bar, electronic current instrument, it is characterized in that described probe be a kind of with elastomeric material as insulation sheath " U " type magnet probe, outside described electronic current instrument independence insulating bar, be connected with bar by insulated conductor.
Described insulating bar is segment type, adapts to different pole heights by different combinations.
Described insulating bar afterbody is provided with the connecting line jack 2 be connected with electronic current instrument, is connected with the connecting line jack of two on electronic current instrument by insulated conductor.
The beneficial effects of the utility model are as follows:
The pincerlike current measuring instrument of rod-type is used for the Road test operation in winter, because electronic current instrument is independent of outside insulating bar, relative flexible during use, avoid over the electronic current instrument display screen that occurs in some measurement situation or the generation of inconvenient reading phenomenon that causes of instrument and survey crew hypertelorism down., because probe external insulation main material is rubber, the reliability that breakage improves safety in production can not be there is under the environment that temperature is extremely low in the pincerlike current measuring instrument of rod-type simultaneously.
Accompanying drawing explanation
Fig. 1 is the pincerlike current measuring instrument front view of rod-type of the present utility model;
Fig. 2 is the pincerlike current measuring instrument side view of rod-type of the present utility model;
Wherein: (1) probe, (2) connect with stirrup, (3) three class B insulation bars, (4) secondary insulation bar, (5) one-level insulating bar, (6) jack, (7) electronic current instrument, (8) rubber base plate, (9) leads for connecting.
Embodiment
As shown in Figure 1-2, the pincerlike current measuring instrument insulating bar of rod-type adopts the withstand voltage 10kV insulating material processing of power industry standard, ensures insulating property and physical strength.Insulating bar divides 3 grades, three class B insulation bars 3, secondary insulation bar 4 and one-level insulating bar 5, and first order length 1.8 meters, two-stage is 1 meter afterwards.Smear yellow insullac outside insulating bar, rubber base plate 9 cushioning effects are arranged at bottom.The body of rod is provided with connecting line jack apart from afterbody 0.3 meter.The internal structure of popping one's head in of new-type probe 1 and plain type is completely the same, form by " U " type magnet, magnet two ends are wound around enough copper coils and are connected to two wires with insulation sheath, wrapped up by the withstand voltage insulating rubber material of 10kV unlike new-type probe 1 outside, elastomeric material will ensure insulativity, indeformable even damaged when ensureing to be subject to External Force Acting simultaneously.Probe bottom fixes 2 at insulating bar top by stirrup, ensures that probe 1 can not rotate.Electronic current instrument 7 is substantially identical with the instrument of plain bar type, is 380V electric current Ground Measuring Device, is divided into two grades, " 1000A " and " 200A ".Be different from plain type, new-type instrument changes upper and lower for the former plain type electronic current instrument back side two attachment plugs into jack 7, connect with connecting wire 9 in use, connecting line is two, length is 1 meter respectively, centre be with insulation sheath parcel the withstand voltage wire of 10kV, wire two ends respectively with plug for being connected with the jack of two in insulating bar main body.Before winter load measurement, first electronic current instrument external wire plug is inserted in insulating bar and electronic current instrument and then start surveying work.
