The protective value of thunder device；Meanwhile, in thunderbolt than more serious area, often there is soil resistivity height, overhead line structures are grounded not
Good the problem of, when there is overvoltage, the arrester on circuit thoroughly can not effectively discharge high current, will form power frequency and continue
Stream vibrates in the line, so as to cause the voltage on circuit to rise, injures the safety of equipment on circuit.
There is partial high pressure transmission line of electricity to use parallel spark gap（Such as lightning protection hardware, overvoltage protection device）Mode is to line
Road is protected, and this mode needs the artificial size that discharging gap is adjusted according to the actual conditions of circuit mount point, expires it
The condition of sufficient air breakdown, therefore live mounting process has influence on the route protection performance of equipment to a certain extent.
The content of the invention
In order to overcome the deficiencies in the prior art, the utility model, which provides one kind, has fixed discharging gap, installs simple
It is convenient, and service life is long, can prevent the high voltage transmission line line protection device of power frequency continued flow.
To realize the purpose, the utility model provides following technical scheme：
A kind of anti-power frequency continued flow discharging gap apparatus, including supports insulative, discharging gap plate, discharging gap bottom electrode and
Pole plate is grounded, the first end of supports insulative is connected with the first end of discharging gap plate, the second of supports insulative
Hold and be connected with being grounded the first end of pole plate, it is characterised in that：Also include power frequency current limiter and drainage system, the power frequency current limiter
It is connected with the second end for being grounded pole plate, the top of power frequency current limiter is connected with discharging gap bottom electrode, the drainage system and institute
State the first end connection of supports insulative.
Further, the drainage system includes wire clamp and the drainage wire being fixed on wire clamp, and the wire clamp is fixedly mounted
On ultra-high-tension power transmission line, one end of the drainage wire is connected with the first end of supports insulative.
Further, discharging gap plate one end lower surface corresponding with the discharging gap bottom electrode is provided with sphere and dashed forward
Rise.
Further, formed between the sphere projection and discharging gap bottom electrode between the atmospherical discharges with fixed range
Gap.
Further, the power frequency current limiter be arrester, Anti-surging device or other there is the device of power frequency current-limiting function.
Further, the ground connection pole plate is mounted by means of bolts on the shaft tower angle steel of transmission line of electricity.
The beneficial effects of the utility model are：
1）Due to having formd the atmospherical discharges gap of fixed range between discharging gap plate and discharging gap bottom electrode,
Regardless of line conditions when therefore installing, all without the distance for manually adjusting discharging gap again, reduce because of in-site installation work
The problem of skill, influences the performance of equipment.
2）In the case of ultra-high-tension power transmission line normal operating voltage, because discharging gap plate and discharging gap bottom electrode do not have
Path is formed, power frequency current limiter is not subject to circuit operation power-frequency voltage, therefore can extend the service life of power frequency current limiter.
3）Most of energy can be discharged by atmospherical discharges gap discharge when line over-voltage occurs, power frequency limit is reduced
The load of device is flowed, overvoltage energy is obtained after effectively release, and power frequency current limiter can block discharging gap plate and discharging gap in time
Power frequency continued flow between bottom electrode, therefore infield need not ensure good earth.

Embodiment
Referring to the drawings 1, between a kind of anti-power frequency continued flow discharging gap apparatus, including drainage system 1, discharging gap plate 2, electric discharge
Gap bottom electrode 3, power frequency current limiter 4, ground connection pole plate 5 and supports insulative 6.The first end of supports insulative 6 passes through bolt
The drainage wire 7 in first end, drainage system 1 with discharging gap plate 2 is connected, and the second end of supports insulative 6 passes through
Bolt is connected with being grounded the first end of pole plate 5.Second end of the ground connection pole plate 5 is connected by bolt with power frequency current limiter 4, institute
The top for stating power frequency current limiter 4 is connected with discharging gap bottom electrode 3.Second end lower surface of the discharging gap plate 2 has ball
Face projection 8.
Referring to the drawings 2, the drainage system 1 includes wire clamp 11 and the drainage wire 7 being fixed on wire clamp 11, the wire clamp
11 are fixedly mounted on ultra-high-tension power transmission line 9, and the drainage wire 7 is connected with the first end of supports insulative 6.It is described to connect
Ground pole plate 5 is mounted by means of bolts on shaft tower angle steel 10.
Because the height value of supports insulative is fixed, therefore the discharging gap bottom electrode 3 and the sphere projection 8
Between formed with fixed range atmospherical discharges gap.
When ultra-high-tension power transmission line meets with thunderbolt or overvoltage occurs, overvoltage is led by the drainage of the drainage system 1
Line 7 is applied to the discharging gap plate 2, when sphere projection 8 and the electricity under the discharging gap of the lower surface of discharging gap plate 2
When fixation the air gap between pole 3 meets air breakdown condition, fixed the air gap is breakdown, now overvoltage produce it is big
Electric current flows into the earth by fixed the air gap and the power frequency current limiter 4, and overvoltage energy is obtained after effectively release, the work
The power frequency continued flow that frequency current limiter 4 is blocked between discharging gap plate 2 and discharging gap bottom electrode 3 in time, makes circuit recover normal.
In the case of ultra-high-tension power transmission line normal operating voltage, due under the discharging gap plate 2 and the discharging gap
Electrode 3 does not form path, therefore the power frequency current limiter 4 is not subject to circuit operation power-frequency voltage, can extend the power frequency
The service life of current limiter 4.
The utility model has fixed discharging gap, installs simple and convenient, and service life is long, can prevent power frequency continued flow
High voltage transmission line line protection device.
