Description
Technical field
The utility model belongs to electrical field, particularly for the combined utensil car of substation grounding device on-the-spot test.
Background technology
Substation grounding device be guarantee electrical equipment under normal and accident conditions reliably and one of the main safety method of safe operation, earth system comprises grounding lattice and grounding jumper, the grounding resistance of earth system refers to, when electric current flows into soil by grounding lattice, the resistance that grounding lattice Soil Surrounding forms, measurement for the grounding resistance of earth system, DL/T596 < < electrical equipment preventive trial rules > > requires regularly the grounding resistance of substation grounding device to be tested, whether the grounding resistance that detects its earth system meets GB requirement, method by the test arrangement measuring electrode of GB regulation is method of lines, the measurement cloth utmost point of method of lines requires voltage pole and the electric current utmost point to arrange point-blank, the cloth utmost point position of the electric current utmost point is, apart from grounding lattice edge-perpendicular distance, by the 4-5 of tested grounding lattice maximum diagonal doubly, the cloth utmost point position of voltage pole is, apart from grounding lattice edge-perpendicular distance by 0.6 times of fixed electric current pole span electrical network edge-perpendicular distance, the catercorner length of general Yi Zuo 220KV substation is about 250 meters of left and right, needs to carry earth electrode 3-5 root, current measurement line, voltage measurement line, hammer, multi-meter, apomecometer, clamp on amperemeter and measure indispensable utensil in test jobs.Because the utensil that will carry is more, heavier, and the layout of measuring line and withdrawal, now completing this test jobs needs many people just can complete, and to surveying work, makes troubles.
Summary of the invention
It is not enough that the purpose of this utility model is to overcome above-mentioned prior art, and a kind of combined utensil car for the on-the-spot test of substation grounding device is provided.
The technical solution of the utility model is to solve like this:
Comprise a car body, in vehicle body upper portion breast board formula container, be not provided with earth electrode groove, electric current drum groove, voltage drum groove, hammer groove, multi-meter groove, apomecometer groove, clamp on amperemeter groove.
Vehicle body upper portion is provided with breast board formula container, is provided with an axletree in the middle of car body bottom with lateral vertical position, and axletree two ends are provided with wheel, car body trailing flank be upwards provided with upwards handcart, car body trailing flank is to being arranged with two supporting legs.
Combined utensil for the on-the-spot test of substation grounding device, combination is novel suitable, kind contains the general conventional measurement apparatus for substation grounding device grounding resistance on-the-spot test operation, easy to use, the scene that is specially adapted to substation grounding device earth resistance operation is used.
The utility model is stored in (available blown plastic casing in the breast board formula container of this car body in designed tote cart by the combined utensil of conventional substation grounding device on-the-spot test, in railway carriage, be prefabricated with for the forming pockets of placing above-mentioned each utensil), be convenient to it to store, transport turnover, the on-the-spot management of using, guarantee on-the-spot use intact, avoid damage and loss because of utensil, cause substation grounding device on-the-spot test work to carry out.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Below in conjunction with 1 pair of content of the present utility model of accompanying drawing, be described in further detail.
The specific embodiment:
With reference to accompanying drawing 1: be respectively arranged with earth electrode groove (1) in vehicle body upper portion breast board container inside, electric current drum groove (2), voltage drum groove (3), hammer groove (4), multi-meter groove (5), apomecometer groove (6), clamp on amperemeter groove (7).Vehicle body upper portion is provided with breast board formula container, in the middle of car body bottom, is provided with an axletree with lateral vertical position, and axletree two ends are provided with wheel, and car body trailing flank is upwards provided with handle upwards, and car body trailing flank is to being arranged with two supporting legs.
The utility model is the combined utensil car for the on-the-spot test of substation grounding device, there is a blown plastic casing, on blown plastic casing inwall, be prefabricated with for each groove of placing the combined utensil of substation grounding device on-the-spot test, in each groove, placed earth electrode, electric current drum, voltage drum, hammer, multi-meter, apomecometer, clamp on amperemeter.Combined utensil car for the on-the-spot test of substation grounding device, combination is novel suitable, kind contains the conventional measurement apparatus for substation grounding device grounding resistance on-the-spot test operation, easy to use, be specially adapted to the keeping that apparatus was used and measured at the scene of substation grounding device earth resistance operation.
