Abstract
The utility model relates to a resistance probe for galvanic circle of an oil-deficiency circuit breaker, which can be used for the testing by lifting the rod on the ground and has the advantages of time saving, labor saving and high safety. An insulating cylinder 4 is connected in the end of an insulating pulling rod, the cylinder 4 is provided with a terminal button 2, an insulating cap 9 is inserted inside, the end part of the cylinder is provided with a conductive probe semicircular column 11 isolated by an insulating board 8, the column 8 is provided with leading wires 10, which is connected into the terminal button 2 through the board 8 and the cap 9, the column 11 outside the cylinder 4 is made into an integral sheet 1, and the end of the sheet 1 is made into the zigzag shape.
Description
The utility model relates to the test probe that the resistance of wiring back is led in the primary cut-out test.
According to the IEC standard code, all want testing conductive resistance loop resistance for " ac hv breaker " that newly put into operation and annual preventive trial and the primary cut-out after the overhaul.Because of the quality of electric conductivity has important effect to the safe operation that guarantees isolating switch.Electric system at present all adopts the traditional test method to the resistance of isolating switch (few oil) galvanic circle of 220KV and 110KV, promptly fasten one's safety belt with two examination inspection personnel, hold 4 lead-in wires of strap clamp and go up isolating switch homophase incision position simultaneously, on two plates of isolating switch, survey galvanic circle resistance with clip.Will climb up 6 person-times for the isolating switch of one group of 220KV like this and just can finish one group of test.An electric substation is stopped a main transformer, then climb up person-time manyly, waste time and energy, also dangerous simultaneously.
The purpose of this utility model is to avoid weak point in the above-mentioned prior art, and provides a kind of not ascending a height can carry out oil-minimum breaker galvanic circle resistance test probe on ground.Time saving and energy saving, and safety.
The purpose of this utility model can reach by the following technical programs, connects insulating cylinder 4 on the insulated tension pole end, on the tube terminal button 2 is housed, and is inserted with insulation plug 9 in the tube, and the symmetric conductor semicolumn 11 of isolating with insulcrete also is equipped with in this end; Passing plug between above-mentioned post 11 leaded 10 warps and the insulcrete is connected on the terminal button 2; The outer post 11 of tube is with body plate shape 1, and blade ends is a zigzag.
The utility model can have following effect than above-mentioned prior art, owing to finish test in terrestrial operation, and time saving and energy saving, safe and reliable.
Fig. 1 is the utility model outside drawing;
Fig. 2 is Fig. 1 complete section figure;
Fig. 3, Fig. 4 are master, the vertical views of first cylindrical probe 11 of figure.
Below in conjunction with accompanying drawing will the utility model is described in further detail:
Shown in Fig. 1,2, on insulated tension pole 6 ends, connect insulating cylinder 4, available bolt connects between the two; Terminal button 2 is equipped with in perforation on the insulating cylinder 4, and terminal button 2 can be connected with tester.Be inserted with insulation plug (9) in the insulating cylinder with shaft shoulder assembling, symmetric conductor semicolumn (11) probe of isolating with insulcrete 8 is equipped with in the end of insulating cylinder, cylinder can slide along wall, passes plug 9 between upward leaded 10 warps of post (11) and the insulcrete 8 and is connected on the terminal button 2.Insulating cylinder 4 outer posts 11 are a body plate shape 1, and sheet 1 end is a zigzag.
Above-mentionedly can between plug 9 and post 11,11 li spring 7 be housed, can adopt organic glass plug 9 in addition in post.
Using method: lead-in wire CP on the QJ42 electric bridge instrument and CP are received respectively on the terminal of two probes, with insulated tension pole two probes are touched on the connecting plate of switch both sides then, reconcile electric bridge and just can measure numerical value.
