Abstract
The utility model discloses a loop resistance subtest stick relates to resistance detection equipment field, and this loop resistance subtest stick includes coaxial test bar barred body, male contact stick, excellent tail, when handcart -type circuit breaker return circuit resistance test, accomplishes that the test wiring is simple, and test data is stable. Without the subtest stick, the time contraction of a circuit breaker loop resistance of test nearly one time, the error has reduced about 30% for the maintenance progress, reduced the power off time, improved work efficiency.
Description
Technical field
The utility model relates to resistance detection apparatus field, particularly a kind of loop resistance subtest rod.
Background technology
10kV handcart type breaker is the emphasis equipment of State Overhaul Test, and major loop resistance test is the attribute testing effectively detecting car switch performance.Handcart type breaker because many reasons test value often differs more with actual value when carrying out power failure test, causes test error excessive, has a strong impact on whether field staff exists hidden danger judgement to equipment.Handcart type breaker moving contact is Mume flower contact, and structure is comparatively special, and when deciding loop resistance test, test clamp cannot clip to suitable test point, is to cause the inaccurate main cause of test findings.Thus study a kind of aid being exclusively used in the test of handcart type breaker loop resistance, improve reliability and the accuracy of loop resistance test data, be conducive to judging switch situation rapidly and accurately, improve overhaul efficiency and benefit.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of loop resistance subtest rod, effectively can solve the problems such as the test caused because test clamp cannot clip to suitable test point in the test of 10KV handcart type breaker loop resistance is difficult, test error is bigger than normal, reach the object improving handcart type breaker loop resistance testing efficiency, reduce error of test data.
For achieving the above object, the utility model provides following technical scheme: a kind of loop resistance subtest rod, it is characterized in that: described loop resistance subtest rod comprises tubular prod barred body, one end of prod barred body is provided with tubular contact rod, the other end of prod barred body is provided with tubular excellent tail, prod barred body, contact rod, excellent tail are all coaxial, and prod barred body, contact are excellent, excellent tail is monolithic construction.
Preferably, described prod barred body, contact rod, excellent tail manufacture by T2 red copper.
Preferably, the diameter of described contact rod is equal with handcart type breaker contact diameter.
Preferably, the diameter of described prod barred body equals the diameter of loop resistance test clamp jaws.
Preferably, the diameter of described excellent tail 5-10 ㎜ larger than the diameter of prod barred body.
Loop resistance subtest rod adopts the metal copper rod consistent with handcart type breaker contact material as raw material, according to the size of contact, makes the portable handcart-type breaker loop resistor subtest rod of a set of different size.
The beneficial effect of above technical scheme is adopted to be: this loop resistance subtest rod is when handcart type breaker loop resistance test, and accomplish that test wiring is simple, test data is stable.Comparatively without subtest rod, nearly one times of the time shorten of a test breaker loop resistor, error-reduction about 30%, accelerates repair schedule, decreases power off time, improve work efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the front view of a kind of loop resistance subtest of the utility model rod;
Fig. 2 is the vertical view of a kind of loop resistance subtest of the utility model rod.
Wherein, 1-prod barred body, 2-contact rod, 3-excellent tail.
Embodiment
The preferred implementation of a kind of loop resistance subtest of the utility model rod is described in detail below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2 shows the embodiment of a kind of loop resistance of the utility model subtest rod: this loop resistance subtest rod comprises tubular prod barred body 1, one end of prod barred body 1 is provided with tubular contact rod 2, the other end of prod barred body 1 is provided with tubular excellent tail 3, prod barred body 1, contact rod 2, excellent tail 3 are all coaxial, and prod barred body 1, contact rod 2, excellent tail 3 are monolithic construction.
Composition graphs 1 and Fig. 2, prod barred body 1, contact rod 2, excellent tail 3 manufacture by T2 red copper, consistent with the material of handcart type breaker contact.The diameter of contact rod 2 is equal with handcart type breaker contact diameter, can ensure that contact rod 2 is good with handcart type breaker contact.The diameter of prod barred body 1 equals the diameter of loop resistance test clamp jaws, can ensure that loop resistance test clamp securely clamps prod barred body 1.The diameter 5-10 ㎜ larger than the diameter of prod barred body 1 of rod tail 3, can prevent loop resistance test clamp from clamping the rear landing of prod barred body 1.
This loop resistance subtest rod meets following technical requirement:
1, loop resistance subtest rod adopts T2 red copper bar to manufacture and through special process process, does not in use produce harmful effect to contact of breaker, and after carrying out test of many times, itself is indeformable, long perfomance life;
2, this loop resistance subtest rod should be able to meet the test demand of all size handcart type breaker that transformer station commonly uses;
3, prod barred body diameter should meet loop resistance test clamp and to dehisce the requirement of size;
4, contact rod mates accurately necessary with handcart type breaker contact.
This loop resistance subtest rod is when handcart type breaker loop resistance is tested, and accomplish that test wiring is simple, test data is stablized.Comparatively without subtest rod, nearly one times of the time shorten of a test breaker loop resistor, error-reduction about 30%, accelerates repair schedule, decreases power off time, improve work efficiency.
Above is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
