Abstract
The utility model provides an arrester resistive current test wiring instrument, the utility model discloses constitute by alligator clip, linking module, probe, thread knob and connecting bolt. The utility model is suitable for a get voltage signal in the transformer substation in the zinc oxide arrester resistive current test on the terminal row. Have the fail safe nature height, arrange go up easy dismounting at voltage terminal, can dismantle in a flexible way, can be in long -time the realization get voltage signal's advantage continually and steadily, accomplish to use manpower sparingly, the enhancement is to the control of risk.
Description
Technical field
This utility model belongs to zinc oxide lightning arrester block property current in high pressure technique testing current in resistance property and transformer station and takes voltage signal jointer structure in testing in terminal block, the power taking pressure signal tool technical field of structures of zinc oxide lightning arrester block property current test in mainly Zinc-Oxide Arrester security status assessment, transformer station.
Background technology
If spark gap is in operation owing to the aging inner member of valve block deteriorates, cause the increase of resistive leakage current, i.e. meritorious loss component continues to increase, so continue deterioration to go down, reach be directed at the most afterwards the thermal runaway of spark gap, if can not be rapidly by the most out of service for abnormal spark gap, it is likely that within a period of time (several month, days or a few hours) explode, power network safety operation will be affected.The method of testing of resistive leakage current is: use electrified tester for zinc oxide arrester to test, voltage signal is obtained from the secondary side with the PT of tested spark gap homophase, current signal is obtained from the enumerator two ends of spark gap, both sides signal introduces the current in resistance property value that test instrunment carries out surveying, the method that voltage signal typically uses pen meter of universal meter to take voltage signal is taken at present at secondary terminals, can not be stable get voltage, device is caused can not stably to receive voltage signal, test result is incorrect, cause and repeat test, waste time and energy, the method risk during voltage adds operation up at charged secondary terminals simultaneously.
Summary of the invention
The purpose of this utility model is precisely in order to solve to take voltage signal difficulty in transformer station's zinc oxide lightning arrester block property current test, test number of repetition is more and that provide one is safe and reliable, and detachable can get voltage signal testing current in resistance property of lightning arrester wiring new tool the most reliably.
The purpose of this utility model is achieved by the following technical solution.
A kind of testing current in resistance property of lightning arrester jointer, this utility model is characterised by, it is made up of alligator clamp, link block, probe, screw knob and connecting bolt；Connecting bolt is fixed on alligator clamp；Link block laterally offers screw thread hole, bottom longitudinal direction, offers connecting hole；Link block is connected with alligator clamp with connecting bolt cooperation by connecting hole；Screw knob screws in screw thread hole and is connected in link block；Offering jack in screw knob front end, probe is inserted in the jack of screw knob.
Fixing hole it is drilled with for fixing connecting bolt in alligator clamp both sides；Probe is built-in spring probe；Link block uses H65 brass ingot, and screw knob is processed for using carbon steel bolt.
The beneficial effects of the utility model are, it is adaptable to the test of transformer station zinc oxide lightning arrester block property current takes voltage signal, have that security reliability is good, insulation, steadiness is good, the advantage that can move flexibly, reliably get voltage signal when can realize long；And have quickly dismount in terminal block, advantage that working specification degree is high.
This utility model alligator clamp be opening be the totally-enclosed alligator clamp of 20mm, it is ensured that the insulating properties of wire clamp, both sides are drilled with the hole of a diameter of 3mm, and hole runs through both sides, easy disassembly connecting bolt.Screw knob is for using carbon steel bolt, and carbon steel is wear-resisting, indeformable, hardness is high, durable non-corrosive, can bear cold and hot working.Meanwhile, link block and screw knob carry out parcel process of insulating, and kit carries out Insulation test, and test result insulation is qualified.
Below in conjunction with the accompanying drawings and specific embodiment is expanded on further this utility model content.

Detailed description of the invention
Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of testing current in resistance property of lightning arrester jointer, this utility model is characterised by, it is made up of alligator clamp 1, link block 3, probe 2, screw knob 4 and connecting bolt 5；Connecting bolt 5 is fixed on alligator clamp 1；Link block 3 laterally offers screw thread hole 3.2, bottom longitudinal direction, offers threaded connection hole 3.1；Link block 3 is connected with alligator clamp 1 with connecting bolt 5 cooperation by connecting hole 3.1；Screw knob 4 screws in screw thread hole 3.2 and is connected in link block 3；Offering jack 4.1 in screw knob 4 front end, probe 2 is inserted in the jack 4.1 of screw knob 4.
Fixing hole 1.1 it is drilled with for fixing connecting bolt 5 in alligator clamp 1 both sides；Probe 2 is built-in spring probe；Link block 3 uses H65 brass ingot, and screw knob 4 is processed for using carbon steel bolt.
This utility model embodiment alligator clamp 1 both sides are drilled with the fixing hole 1.1 of a diameter of 3.0mm, it is drilled with the connecting hole 3.1 of vertical diameter 3.0mm and screw thread hole 3.2 that trans D is 6.0mm in link block 3 upper bottom portion, screw knob 4 is processed for using carbon steel bolt, bolt front end is drilled with the jack 4.1 of diameter 2.4mm, it is simple to probe inserts.
This utility model manufacture method is:
1, this utility model needs the alligator clamp, probe, link block, screw knob and the connecting bolt material that use all can directly buy.Building block can be carried out assembly and disassembly, probe can be realized for how to design can effectively release and termination contact, and get voltage time long reliably and We conducted detailed analysis, first wire clamp is reliably capable clamping on the terminal of all types of size, and can reliably release probe, effectively can contact with voltage terminal, reliably get voltage.By using the pyrite of H65 to be attached the processing of module, link block is connected with alligator clamp by the hole at link block vertical drill diameter 3.0mm by connecting bolt, it is the hole of 6mm at the horizontal drill diameter of link block, screw knob uses the carbon steel bolt of 6mm to be processed, be drilled with the hole of diameter 2.4mm at bolt top, screw knob can screw in that hole that the horizontal drill diameter of link block is 6mm is horizontal with connection module to be connected.Insert a probe in the hole of screw knob top 2.4mm, complete the assembling of package unit.
2, this utility model is in order to ensure the safety used, and link block and screw knob carries out parcel process of insulating, and to the kit being completed by insulation and voltage-withstand test, insulate qualified, meet charged use requirement under low voltage situations.
