Abstract
The present invention relates to a 10kV cable branch box loop resistance testing tool which is characterized in that one end of a body is provided with a threaded connection end, a wiring plate is arranged on the threaded connection end, and the other end of the body is provided with a square operation end. During the test, the threaded connection end can be directly connected to the terminal of a cable branch box, good contact can be ensured by the wiring plate, the use of studs and lugs is not needed, the operation end is square and is provided with an opening groove, and the operation of tools such as a screwdriver and pliers is facilitated. The test time is effectively shortened, and the test procedures are simplified. In addition, the threaded connection end is connected through a slide way, the overall diameter of the threaded connection end can be adjusted, the threaded connection end can be conveniently connected to different sizes of connection terminals, the use range is wide, and the cost is saved.
Description
Technical field
The present invention relates to a kind of electric system test instrument, refer in particular to a kind of 10kV cable branch box loop resistance test instrument.
Background technology
10kV cable branch box divides several intervals, and in an interval, 3 ABC terminals, complete the connection at each interval by internal switch.
When 10kV cable branch box does loop resistance test, object is that in detection streamer feeder pillar, whether switch circuit resistance reaches requirement.During test, be that the A terminal in an interval is connect test connection, the A terminal in another interval also connects test connection, detects the contact situation of these two switches.Complete an interval one phase loop resistance test, be with the ABC phase at an interval for benchmark, test the loop resistance of the ABC tri-at each interval respectively.
In prior art, be coordinate together with Wiring nose with the annex stud bolt in cable branch box, stud bolt press against Wiring nose and be screwed on the terminal of cable branch box.When doing experiment, if be the A phase at interval each in cable branch box is connected stud bolt and Wiring nose, test loop resistance successively when quantity allows.Due to the annex limited amount of cable branch box, can not testing requirements be met, test period and workload are increased all greatly.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of 10kV cable branch box loop resistance test instrument is provided, solves the problem that in prior art, loop resistance experiment work amount is large.
Technical scheme of the present invention is as follows:
One end of body arranges threaded ends, and the top of threaded ends is provided with patching panel, and the other end of body is set to square operating side.
Described threaded ends is made up of three slide blocks, and the outside surface of three slide blocks arranges screw thread, and three slide blocks are slidably connected by slideway and patching panel.
The end face of described square operating side is provided with cross-shaped aperture groove.
Advantageous effect of the present invention is as follows:
During test, can directly be connected on the terminal of cable branch box by threaded ends, patching panel can ensure that contact is good, and without the need to using stud bolt and Wiring nose, operating side is set to square and is provided with open recess, the tool operation such as convenient screwdriver, pliers.Effective shortening test period, short form test program.In addition, threaded ends is connected by slideway, can adjust threaded ends integral diameter, is conveniently connected with the splicing ear of different size, and usable range is wide, saves cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is threaded ends end face structure schematic diagram of the present invention.
Fig. 3 is the present invention square operating side end face structure schematic diagram.
In figure, 1, threaded ends, 2, square operating side, 3, patching panel, 4, slide block, 5, open recess.
Embodiment
Further illustrate this use is novel below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, body adopt conductive intensities high, contact good chromium plating high-strength stainless steel, as main material, one end of body arranges threaded ends 1, the top of threaded ends 1 is provided with patching panel 3, threaded ends is made up of three slide blocks 4, and the outside surface of three slide blocks 4 arranges screw thread, and three slide blocks 4 are slidably connected by slideway and patching panel 3; The other end of body is set to square operating side 2; The end face of square operating side is provided with cross-shaped aperture groove 5.
Protection scope of the present invention is as the criterion with claims, does not limit by specific embodiment.
