Description
Technical field
The utility model belongs to power construction utensil, and more particularly to a kind of binodal arrester non-dismantle high voltages fuse experiment is auxiliary
Help device.
Background technology
Metal oxide arrester is one of Important Components of transformer station, and it mainly limits system overvoltage, protection
Electrical equipment.The metal oxide arrester of transformation station is generally binodal mounting structure, DC voltage and pond leakage in routine test
Current testing is one of main experimental project, it usually needs removes a high-voltage connection and carries out section by section from top to bottom.This experiment
There are many problems in method, such as 220KV voltage class metal oxide arrester volumes are larger, installation position in testing at the scene
Put and high, experiment, which is taken out stitches, every time is required for lift truck or uses large-scale staircase, and time-consuming greatly for workload；Worked when removing lead
Place is high away from ground level, deposits that induced voltage is big, and operating risk is big during brownout；Repeated disassembled and assembled lead, lead may be caused
The hidden danger such as damage and screw loose contact；Part arrester is limited by installation site, and high-voltage connection is short, removes lead and upper section is kept away
When thunder device is tested, the high-pressure section of equipment can not meet to test needs with the distance of neighbouring device lead, such as further tear open
Except relevant device lead can sharply increase workload and operating risk.
The content of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, there is provided it is a kind of simple in construction, securely and reliably, time saving province
Power binodal arrester non-dismantle high voltages fuse experiment auxiliary device.
The utility model solves the technical scheme that technical problem uses：Binodal arrester non-dismantle high voltages fuse experiment auxiliary
Device includes metal oxide arrester, folds tripod, DC ammeter, is characterized in being fitted with absolutely in folding tripod
Edge fixed plate, insulation fixing plate are fitted with hard copper bar, and the lower end of metal oxide arrester is installed on hard copper bar and absolutely
The left end of edge fixed plate is fixed with locking nut, and the right-hand member of hard copper bar is fitted with binding post one, insulation fixing plate right-hand member
Below fixation DC ammeter is housed, be respectively provided with binding post two and binding post three, binding post on DC ammeter
Connected between one and binding post two with cable, binding post three connects with ground wire.
The beneficial effects of the utility model are：Binodal arrester non-dismantle high voltages fuse experiment auxiliary device is simple in construction, no
With dismounting high-voltage connection, it is possible to carry out pond leakage current experiment, the hidden danger of lead damage and screw loose contact can be avoided, both
Time saving and laborsaving, test efficiency is high, securely and reliably.
Brief description of the drawings

Fig. 1 is binodal arrester non-dismantle high voltages fuse experiment auxiliary device structure chart.
In figure, 1- metal oxide arresters；2- insulation fixing plates；3- hard copper bars；4- DC ammeters；5- terminals
Son one；6- binding posts two；7- binding posts three；8- folds tripod；9- locking nuts；10- cables；11- is grounded.
Embodiment
Embodiment, referring to the drawings 1, above the folding tripod 8 of binodal arrester non-dismantle high voltages fuse experiment auxiliary device
Equipped with insulation fixing plate 2, insulation fixing plate 2 is fitted with hard copper bar 3.The lower end of metal oxide arrester 1 is installed on firmly
The left end locking nut 9 of matter copper bar 3 and insulation fixing plate 2 is fixed, and the right-hand member of hard copper bar 3 is fitted with binding post 1,
Fixation is equipped with DC ammeter 4 below the right-hand member of insulation fixing plate 2, and binding post 26 and wiring are respectively provided with DC ammeter 4
Terminal 37, connected between binding post 1 and binding post 26 with cable 10, the connection of binding post 37 ground wire 11.
The application method of binodal arrester non-dismantle high voltages fuse experiment auxiliary device is：The structure of binodal arrester is upper section
Arrester, lower bound arrester and base, high-voltage connection need not be removed using the present apparatus during experiment., will when arrester is saved in experiment
The HV Terminal of the lower end connection metal oxide arrester 1 of lower section arrester, the electricity consumption of binding post 1 on hard copper bar 3
Cable 10 connects binding post 26, the binding post 37 on DC ammeter 4 ground connection of ground wire 11, DC generator high pressure
The reading of side microampere meter is I, and the reading of DC ammeter 4 is I1,Work as I-I1=1 MAH, flow through the electric current of section arrester i.e.
For 1 milliampere, now the output voltage of high voltage direct current generator is 1 milliampere of reference voltage of direct current of upper section arrester, when being reduced to
75%1 MAHs, electric current I-I1Leakage Current under as 75%1 milliamperes of reference voltages；During lower section test of lightning arrester, pressing position
It is constant, upper section arrester lower end（Descend the upper end of section arrester）Add high pressure, by metal oxide on the basis of last time wiring
The HV Terminal of arrester 1 and the short circuit of binding post 1 of hard copper bar 3, the reading I of DC ammeter 41For 1 MAH, direct current
The output voltage of high pressure generator is the reference voltage of 1 milliampere of the direct current of lower section arrester, when being reduced to 75%1 MAHs, electric current
I1Leakage Current under as 75%1 milliamperes of reference voltages.
