Description
Technical field
The present invention relates to one kind can hot line job discharge prevention ball gap, belong to discharge protector technical field.
Background technique
Currently, discharge prevention ball gap is the identical spheric electrode of a pair of of diameter both at home and abroad, can be used in various high-pottings
In high-tension measurement and protection subject article.However it is all fairly simple to the research of discharge prevention ball gap, do not account for various aspects
Safety, convenience etc..
(1) it is inconvenient to adjust, also inaccurately；
(2) due to the limitation of testing equipment and condition, the problems such as structure is single, weight of equipment is overweight；
(3) in product charging test, electrode distance cannot be adjusted in time, need just be adjusted after discharging.
Summary of the invention
The present invention in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of structurally reasonable, structure is simple, it is small in size, easy to carry,
Can hot line job discharge prevention ball gap.
Thus the technical solution adopted by the present invention is that: the present invention includes pedestal (1), and two be arranged on pedestal (1) are corresponding
The insulated leg (2) of setting；
It is provided with moving electrode (3) on the insulated leg (2) of side, is provided with stationary electrode (4) on the insulated leg (2) of the other side,
The moving electrode (3) is driven by cylinder (5)；
It is additionally provided with the detection device of detection moving electrode (3), stationary electrode (4) position.
The detection device is infrared limiting device.
The pedestal (1) is aluminum alloy base.
The invention has the advantages that the present invention pushes protective ball gap using cylinder, there is good flexibility.Greatly avoid
The case where artificial electric shock, the safety of equipment is enhanced, by connecting gas source, pushes moving electrode can be more precisely with cylinder
Guarantee the gap between moving electrode and stationary electrode, so as to the product of the various different voltages grades of measurement and protection, realizes one
Object is multi-purpose.
The present invention pushes protective ball gap using cylinder, has good flexibility, safety and convenience.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
1 it is pedestal in figure, 2 be insulated leg, 3 be moving electrode, 4 be stationary electrode, 5 is cylinder.
Specific embodiment
The present invention includes pedestal 1, the insulated leg 2 that two be arranged on pedestal 1 are correspondingly arranged；
It is provided with moving electrode 3 on the insulated leg 2 of side, stationary electrode 4, the dynamic electricity are provided on the insulated leg 2 of the other side
Pole 3 is driven by cylinder 5；
It is additionally provided with the detection device of detection moving electrode 3,4 position of stationary electrode.
The detection device is infrared limiting device.
The pedestal 1 is aluminum alloy base.
The course of work of the invention are as follows: after the present invention connects gas source, push moving electrode 3 toward 4 direction of stationary electrode by cylinder 5
It is mobile, by infrared ray limiting device, 5 stop motion of cylinder, at this time between moving electrode 3 and stationary electrode 4 behind arrival designated position
Guarantee effective distance, forms protection.When changing test product voltage, can by change 5 stroke of cylinder come change moving electrode 3 with it is quiet
Effective distance between electrode 4 has the function that protect test product and increasing apparatus under different voltages.
Claims (3)
