Abstract
The utility model discloses a special instrument box for a grounding resistance tester. The special instrument box comprises a box body and a box cover, wherein more than four partition plates are arranged in the box body and are used for dividing the box body into more than five cavities; a notch is formed in one of the cavities; a box door is formed in one side of the box body and is connected with the box body through a hinge; two connected cavities are formed in the box body corresponding to the box door; a wire reel is arranged in the two connected cavities and is connected with a crank outside the box body through a bearing; and the box cover is connected with the box body through a hinge. The special instrument box is conveniently carried outdoors, and by stabilizing an instrument in the special instrument box, the problem of shaking and swinging is solved, so that the measurement accuracy is effectively improved, and the damage to the instrument caused by water soaking in the stormy weather is avoided. Additionally, with the special crank and the special winding and unwinding wire reel, a mechanical wire winding and unwinding mode replaces a manual wire winding and unwinding mode, so that the instrument is not limited by ground conditions, and an electric wire can be wound and unwound freely and conveniently.
Description
Technical field
The utility model relates to a kind of earth resistance tester meter specially case.
Background technology
" voltage transformer operating standard ", " rural area low-voltage power technical regulation " regulation: total volume is at 100 kilovolt-amperes and above voltage transformer, and the grounding resistance of earth system should be not more than 4 ohm; Total volume is at the voltage transformer below 100 kilovolt-amperes, and the grounding resistance of earth system should be not more than 10 ohm.Measurement of Grounding Resistance is the big event of checking and accepting before voltage transformer installation completion puts into operation.
According to grounding resistance measurement operating standard flow process, manual measurement is taked in the measurement of grounding resistance at present, manual people's retractable cable, and the fixing and distant action instrument of another people, but there is following problem in this kind when measuring:
1, connection lead twines, opens up and put difficulty.Different staff is to the winding shape disunity of ground resistance measuring instrument connecting wire, the rough retractable operation that has, phenomenons such as knotting, high distortion can appear in depositing, this situation has produced very big influence to the use of ground resistance measuring instrument in working next time, and What is more can have influence on the correctness of measuring resistance.
2, be subjected to the influence of topography bigger.In different working environments, when running into the ground unfairness,, when the earthometer remote measurement, instrument can occur and rock swing because the ground resistance measuring instrument ground contact area is little, can't measure the phenomenon that causes measured error big.
3, go out to carry inconvenience.Tester comprises three part of devices: one of (1), ZC-8 type earth resistance tester; (2), the auxiliary earth rod is two; (3), lead 5m, 20m, 40m are each one; Hammer also will be carried in the scene in addition.Owing to do not concentrate and receive dress, cause and go out to carry inconvenience.
The utility model content
The utility model provide a kind of can be together with various instrument combination, and easy to carry, solve and rock swing. the earth resistance tester meter specially case of mechanical retractable cable.
To achieve these goals, the technical solution adopted in the utility model is:
Earth resistance tester meter specially case, comprise casing and case lid, it is characterized in that: the dividing plate more than four is arranged in the described casing, described dividing plate is divided into cavity more than five with casing, one of them cavity is provided with a breach, described casing front side has chamber door, described chamber door links to each other with casing by hinge, be provided with the cavity that links to each other more than two in the corresponding casing of described chamber door, be provided with bobbin in the described cavity that links to each other more than two, described bobbin links to each other by bearing with casing crank outward, and described case lid links to each other with casing by hinge.
Preferably, described casing is divided into former and later two cavitys by the dividing plate of a horizontally set, and described fwd cavity is divided into four cavitys by three dividing plates of placing vertically.
Preferably, described case lid and chamber door are provided with the snap close that is complementary.After the folding and unfolding of various instrument instrument is good, chamber door and case lid can be shut, buckle by the snap close that is complementary on case lid and the chamber door.
Preferably, described casing both sides are provided with handle.Handle can make things convenient for the user to carry casing.
Preferably, described casing is the corrosion-resistant steel casing, and described case lid is the corrosion-resistant steel case lid.
The beneficial effects of the utility model:
The utility model can be with the related tool of earth resistance tester, all combine as draw drum, meter specially case and earth bar, conveniently go out to carry, instrument is stabilized in the meter specially case, solved and rocked vibration problems, thereby. effectively improved measuring accuracy, avoided wind and rain weather instrument to damage simultaneously because of immersion.Zhuan Yong crank and folding and unfolding bobbin have been realized making instrument not limited by surface condition by mechanical retractable cable instead of manual retractable cable in addition, and have stopped the mutual winding between different conductor, and the folding and unfolding lead shrinks freely, conveniently answers hand.
