Abstract
The utility model provides a clip-shaped grounding resistance tester which comprises a handle and a jaw which is in a shape of the English capital letter D. The handle is connected to the jaw. The lower end of the handle is provided with a liquid crystal display screen to display the value of grounding resistance. One side of the handle is provided with a clamp handle, the internal part of the clamp handle is connected with the jaw, and the opening and closing of the jaw are controlled. The clip-shaped grounding resistance tester can clamp a ground down lead which is laid against a wall and has a large cross section area, and the clip-shaped grounding resistance tester has the advantages of wide application range, labor-saving pressing and easy carrying.
Description
Technical field
The utility model relates to earth resistance tester, particularly relates to a kind of pincerlike earth resistance tester.
Background technology
Pliers-shape earthing resistance instrument is a kind of novel grounding resistance measurement instrument.When measurement has the earthed system in loop, do not need to disconnect down conductor, do not need auxiliary electrode, safely and fast, easy to use.But a lot of down conductors lay by wall, some material section is long-pending slightly large, often causes jaw cannot block measured object.In addition, need to use larger strength to press clamp handle and just can open jaw, when test point is more, be very easy to cause fatigue.The 3rd, tester conventionally need to be contained in pincerlike earth resistance tester in case and carry, and during follow-on test, takes inconvenience.We have invented a kind of new pincerlike earth resistance tester for this reason, have solved above technical matters.
Summary of the invention
The purpose of this utility model is to provide a kind of blocking by wall and lays the downlead larger with sectional area, presses clamp handle comparatively laborsaving, the pincerlike earth resistance tester being simultaneously convenient for carrying.
The purpose of this utility model can be achieved by the following technical measures: pincerlike earth resistance tester, this pincer earth resistance tester comprises handle and jaw, this jaw is capitalization English letter D shape, this handle is connected in this jaw, its lower end is provided with LCDs, and to show grounding resistance, the side of this handle is provided with clamp handle, this clamp handle inside is connected in this jaw, and controls the folding of this jaw.
The purpose of this utility model can be achieved by the following technical measures:
The vertical side thickness of this jaw is 1~2 centimetre.
This handle also comprises power switch and functional switch, and this power switch and this functional switch are positioned at the upper end of this handle, and this power switch is for start or shutdown, and this functional switch is used for browsing storage data.
This handle also comprises and buckling, and this buckles the back side that is positioned at this handle, so that hang this pincer earth resistance tester.
This handle also comprises battery case, and this battery case is positioned at the back side of this handle, to place the battery of this pincer earth resistance tester.
The length of this clamp handle is 7~8cm.
Pincerlike earth resistance tester in the utility model, comprise handle and jaw, handle is provided with power switch, functional switch, liquid crystal display, clamp handle, and described jaw is capitalization English letter D shape, for the stake resistance of non-cpntact measurement electrical equipment and lightning protection device.Because the vertical side thickness of jaw is 1~2 centimetre, the thickness that more existing pincerlike earth resistance tester is 5 centimetres reduces greatly, can be applicable to more measured object.D clamp mouth design has increased internal diameter, can clamp the measured object of the special shapes such as measured object that sectional area is slightly large or angle steel, steel pipe.Clamp handle has been carried out extension design, has increased the moment while pressing, and can reduce to press strength, is convenient to personnel's continued operation.The handle back side is provided with and buckles, and can be hung on waistband or other places that can hang, and is convenient for carrying and takes.The beneficial effects of the utility model are, can clamp by wall and lay the down conductor larger with sectional area, and usable range is wide, presses laborsaving, easy to carry.
Accompanying drawing explanation
Fig. 1 is the front view of pincerlike earth resistance tester of the present utility model;

Embodiment
For above and other object of the present utility model, feature and advantage can be become apparent, cited below particularly go out preferred embodiment, and coordinate appended graphicly, be described in detail below.
If Fig. 1 is to as shown in Fig. 3, the front view that Fig. 1 is pincerlike earth resistance tester of the present utility model; Fig. 2 is the rear view of pincerlike earth resistance tester of the present utility model; Fig. 3 is pincerlike earth resistance tester of the present utility model schematic diagram in use.This pincer earth resistance tester is comprised of handle and jaw 1, and handle is provided with power switch 2, functional switch 3, LCDs 4, clamp handle 5, and the handle back side is provided with and buckles 6, battery case 7.
Jaw 1 is capitalization English letter D shape, has increased internal diameter, can clamp measured object that sectional area is slightly large or the measured object of the special shape such as angle steel, steel pipe.The vertical side thickness of jaw 1 is 1~2 centimetre, and the thickness that more existing pincerlike earth resistance tester is 5 centimetres reduces greatly, can be applicable to more measured object.
Handle is connected in this jaw 1, and its upper end is provided with power switch 2 and functional switch 3, and this power switch 2 is for startup and shutdown, and this functional switch 3 is for browsing storage data.
In the example shown in Fig. 3, first turn on the power switch 2, then press clamp handle 5 and open D clamp mouth 1, a vertical side is inserted in the gap of downlead 8 and metope, unclamp clamp handle 5, a side of jaw 1 arc is contacted with a vertical side, form closed-loop path.Finally from LCDs 4, read the numerical value of measuring.
