Description
Technical field
The invention belongs to transformer substation arrester measurement testing equipment technical field, more particularly to a kind of transformer substation arrester inspection
Survey fault diagnosis system and its method.
Background technology
Effect of the arrester in overhead transmission line mainly discharges the overvoltage such as thunder and lightning, protect electrical network and electrical equipment from
Instantaneous overvoltage endangers, so as to ensure the safe and stable operation of transmission line of electricity and electrical equipment.
At present, 35kV, 66kV, 110kV, 220kV, 550kV electric pressure arrester is installed outdoors, due to by tide
The outer long-time such as wet, sleet, corrosion corrodes, and metal parts is easy to corrosion, and extremely difficult cleans out.It is electric when arrester is carried out
During conductive flow measurement, due to the impact of rusty stain, cause loose contact, it is difficult to accurately measurement arrester conduction current, gives test work
Make troubles, can notably cause erroneous judgement.Traditional method of testing needs staff to ascend a height to be operated, will be had rusty stains
Metal parts clean out, operation require it is higher, need at least two people wire could be bundled in metal parts upper boom,
And labour intensity very big, efficiency is low, and need after cleaning out by test lead colligation on metal parts, due to test
Electric current is huge, needs diameter of wire big, and wire quality is big, easily causes colligation and obtains defective tightness, in operation, will send out at colligation
Heat, or even wire is burnt, affect test effect and test effect.
The content of the invention
Present invention aim at solving above-mentioned technical problem, there is provided a kind of transformer substation arrester detection fault diagnosis system and
Its method, does not only need a people just can to move to wire is time saving and energy saving on arrester metal parts, and wire and metal
Component contact is good, the corrosion thing of the cleaning metal parts that need not ascend a height, and labour intensity is very little, wiring efficiency high.
For achieving the above object, the technical scheme is that：A kind of transformer substation arrester detects fault diagnosis system, bag
Include one end be provided with installing hole elastic conducting electroplax, be arranged on vertical section on elastic conducting electroplax for isosceles trapezoidal structure pilot hole,
Be arranged at the conducting rod of insulating telescopic bar upper end, the conducting rod top is pyramidal structure, the size on the conducting rod top with
The inner chamber of pilot hole matches, and the week side of boss of the conducting rod upper taper structure arranges fine and closely woven cutter tooth, and the conducting rod bottom sets
Put wire automatic impaction release mechanism.
The wire automatic impaction release mechanism includes being sleeved on the bearing of conducting rod bottom, is arranged on bearing upper bracket,
The arc lever being hinged is set on the support, and the arc lever upper end arranges the week side of boss phase with conducting rod upper taper structure
The arc electric-conductor of matching, the bearing bottom arranges and arrange in bearing corresponding with support, the bearing internal with magnetic

3）Insulating telescopic bar is rotated, insulating telescopic bar band moving conductive rod upper taper structure is rotated and is directed to hole internal corrosion thing
Clean out, conducting rod upper taper structure is rotated in bearing, insulating telescopic bar is rotated will not drive wire to rotate；
4）Again rotating operation bar makes conductive plate being sleeved on conducting rod tightly, adjusts the length of insulating telescopic bar, makes
Ground is inserted in insulating telescopic bar lower end, makes insulating telescopic bar fixation；
5）The power supply of electromagnetic sleeve in bearing is disconnected, under the action of the spring magnetic push rod pulls arc lever to move out and makes
The arc electric-conductor of arc lever upper end is in close contact with conducting rod, due to the effect support of spring it is tight with arc lever contact
Well, support is connected with wire, and wire is connected with the test equipment on ground.
Compared with prior art, the invention has the beneficial effects as follows：Just elastic conducting electroplax is arranged on when filling arrester first
On conductive component, afterwards monthly routine test arrester when, without the need for stepping on bar operation, only need to be by the conduction on insulating telescopic bar top
In pilot hole on bar insertion conductive plate, even if pilot hole internal corrosion, only needed gently by the fine and closely woven cutter tooth being arranged on conducting rod
Light to rotate the just band moving conductive rod rotation of insulating telescopic bar, the corrosion thing that can be easily directed in hole is cleaned out, and makes conducting rod
It is in contact with the electrically conductive plates well, contact position will not be made to generate heat；Wire automatic impaction release mechanism is set on conducting rod simultaneously, it is described to lead
Line automatic impaction release mechanism includes being sleeved on the bearing of conducting rod bottom, is arranged on bearing upper bracket, arranges on the support

Part, the bearing bottom arranges and arrange in bearing corresponding with support, the bearing the internal electromagnetic sleeve with magnetic push rod, magnetic
Property push rod be connected by spring with rest base, the magnetic push rod is hinged with the lower end of arc lever, cleaning pilot hole in
Corrosion when, rotate insulating telescopic bar wire will not be driven to rotate, be wrapped on insulating bar so as to avoid wire, increase operation
Difficulty, it is even more important that the big quality of diameter of wire is focused on and during rotation insulating telescopic bar wire will not be driven to rotate, and is operated
Difficulty is minimum time saving and energy saving.After the corrosion thing being directed in hole is cleaned out, again rotating operation bar makes conductive plate set tightly
It is mounted on conducting rod, adjusts the length of insulating telescopic bar, make insulating telescopic bar lower end insert ground, makes insulating bar fixation；
The power supply of electromagnetic sleeve in bearing is disconnected, under the action of the spring magnetic push rod pulls arc lever to move out and makes on arc lever
The arc electric-conductor at end is in close contact with conducting rod, due to effect support and the arc lever contact of spring it is closely good, support
It is connected with wire, wire is connected with the test equipment on ground.The insulating telescopic bar lower end arranges spine.The elastic conduction
The thickness of plate is 2cm～5cm, and, in 2cm～5cm, conducting rod is suitable with pilot hole contact area, Neng Gouqi for charged plates THICKNESS CONTROL
To good electric action；The elastic conduction plate level is arranged on the conductive component of arrester.Through inventor more than 100 times
Test, is only needed to 5 minutes using the device of the present invention in whole test process, and what is more important only needs the people just can be complete
, there is not some poor wire connections and conductor overheating phenomenon, fault rate in more than 100 test process in whole test job
It is extremely low.And same test job is faced, and conductive component is cleared up using a traditional people high-altitude and wire is bundled, a people exists
Test on ground, whole measurement process at least needs easily to be generated heat after 3 hours, and wire binding, burns wire, while work
