Description
Technical field
It the utility model is related to a kind of distribution line overvoltage protection device experimental rig.
Background technology
Arrester can all have a rated operational voltage dispatching from the factory, i.e., when overvoltage exceedes rated operational voltage, arrester
Just discharge over the ground, but the performance of arrester can not accomplish all unanimously, that is, the underproof situation of arrester occurs, such as to exist
When overvoltage is also not above rated operational voltage, arrester just discharges, or after overvoltage exceedes rated operational voltage, keeps away
The problem of thunder device does not discharge still, and at present not for the whether qualified experimental rig of arrester rated operational voltage, to disappearing
Expense person brings puzzlement, while there are security risk.
The content of the invention
The purpose of this utility model is in view of the deficiencies of the prior art, there is provided a kind of nominal operation electricity for testing arrester
A kind of whether qualified distribution line overvoltage protection device experimental rig of pressure.
The purpose of this utility model is realized by following technical solution：
Whether a kind of distribution line overvoltage protection device experimental rig, the rated operational voltage for testing arrester close
Lattice, including distribution line, arrester, counter, thunder and lightning simulator and controller, thunder and lightning simulator connection distribution line are used
In applying test voltage to distribution line, controller connects and controls the working status of thunder and lightning simulator, and arrester one end is set
Be equipped with spaced apart with distribution line arc electrode other end ground connection, counter be connected to the other end of arrester it
Between, during experiment, thunder and lightning simulator applies test voltage to distribution line, distribution line is worked as arrester to lightning arrester discharge
When the test voltage born exceedes its actual operating voltage, arrester discharge over the ground unison counter record discharge time, pass through
Observation counter judges whether arrester discharges, and real work voltage is found by change trial voltage, by comparing actual work
Make voltage with rated operational voltage to judge whether the rated operational voltage of arrester is qualified.
Further, further include supporting rod, be arranged on supporting rod top be used for zinc oxide surge arresters insulating mounting frame, set
The insulator of distribution line is used to support in insulating mounting frame.
The utility model has the advantages that：
During experiment, when the test voltage that arrester is born exceedes its actual operating voltage, arrester discharges at the same time over the ground
Counter records discharge time, judges whether arrester discharges by observing counter, and reality is found by change trial voltage
Operating voltage, judges whether the rated operational voltage of arrester closes by comparing real work voltage with rated operational voltage
Lattice, when real work voltage deviation rated operational voltage is larger, then judge that the rated operational voltage of the arrester is unqualified, from
And conveniently and efficiently judge whether arrester is qualified.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
Embodiment
With reference to shown in Fig. 1, a kind of distribution line overvoltage protection device experimental rig, for testing the specified work of arrester 5
Whether qualified make voltage, including distribution line 3, arrester 5, counter 7, thunder and lightning simulator 2, controller 1, supporting rod 9, absolutely
Edge mounting bracket 6 and insulator 8.
Supporting rod 9 is vertically arranged on the basis of bottom surface, and arrester 5 is arranged on 9 top of supporting rod by being insulated frame 6,
Distribution line 3 is supported on by insulator 8 and is insulated on frame 6, and thunder and lightning simulator 2 connects distribution line 3 and is used for distribution
Circuit 3 applies test voltage, and controller 1 connects and controls the working status of thunder and lightning simulator 2, and 5 one end of arrester is provided with
Spaced apart with distribution line 34 other end of arc electrode ground connection, counter 7 be connected to the other end of arrester 5 it
Between, during experiment, thunder and lightning simulator 2 applies test voltage to distribution line 3, distribution line 3 is discharged to arrester 5, when keeping away
When the test voltage that thunder device 5 is born exceedes its actual operating voltage, arrester 5 discharge over the ground unison counter 7 record electric discharge time
Number, judges whether arrester discharges by observing counter 7, finds real work voltage by change trial voltage, pass through ratio
Whether the rated operational voltage of arrester is qualified to be judged with rated operational voltage to real work voltage.
The above, is only the preferred embodiment of the utility model, therefore the utility model implementation cannot be limited with this
Scope, i.e., the equivalent changes and modifications made according to present utility model application the scope of the claims and description all should still belong to this
In the range of utility model patent is covered.
Claims (2)
1. a kind of distribution line overvoltage protection device experimental rig, whether the rated operational voltage for testing arrester is qualified,
