Transmission system overvoltage can seriously threaten the stability of direct current transportation and bulk power grid operation.DC converter station largely configures zinc oxide
Direct current arrester group prevents overvoltage from damaging direct current transportation equipment.It is set in reasonable Allocation of Lightning Arrester energy effective protection converter station
It is standby, system operation reliability is improved, the cost of investment of equipment is reduced, is optimal in technical and economy.It is changed to meet
Stream stand in arrester big energy absorption requirement, in domestic and international DC engineering, direct current arrester is usually designed to multicolumn parallel connection and keeps away
Thunder device group.To guarantee that the dash current equilibrium of each column arrester is flowed through in energy release in the process, each column arrester must have base
This consistent operation characteristic.If having a column arrester since humidified insulation or valve block deteriorate in whole group, the column residual voltage of arrester
It reducing, shunting sharply increases, and cumlative energy far surpasses itself thermal capacity, and it causes punch through short circuit and explodes, the failure of whole group arrester, directly
Streaming system forced outage.The problem of causing the failure of whole group arrester due to single-column surge arrester failure in the urgent need to address thus.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of high-voltage fuse type direct current arrester, it can be ensured that
Remaining arrester group operates normally, and improves DC transmission system reliability.
The technical scheme adopted by the utility model to solve the technical problem is as follows: it is lightning-arrest to construct a kind of high-voltage fuse type direct current
Device, including single-column fusing type direct current arrester, the single-column fusing type direct current arrester include the zinc oxide valve plate being connected in series
It is lightning-arrest that unit and fuse, the zinc oxide valve plate unit and fuse form single-column fusing type direct current after epoxy cylinder encapsulates
Device.
In above scheme, multiple single-column fusing type direct current arrester parallel connection post packages form single branch arrester, multiple single branch
Arrester parallel connection forms arrester group in groups.
In above scheme, the zinc oxide valve plate unit is formed after being crimped by multiple zinc oxide valve plate mucilage bindings, the oxidation
Zinc valve block unit is located at below fuse.
In above scheme, wherein one end draws that form single-column fusing type direct current lightning-arrest after zinc oxide valve plate mucilage binding crimping
The lower wiring to form single-column fusing type direct current arrester is drawn in the upper terminals of device, single-column fusing type direct current arrester one end
End.
In above scheme, multiple single-column fusing type direct current arresters are encapsulated by epoxy cylinder, and single-column fusing type direct current is lightning-arrest
Device is arranged along epoxy cylinder center radial.
In above scheme, connected after multiple list branch arresters are in parallel by copper bar.
The high-voltage fuse type direct current arrester for implementing the utility model, has the advantages that
1, the utility model single-column fusing type direct current arrester structure can effectively solve direct current system arrester group single-column
The problem of lightning arrester characteristic failure breakdown, the application that fusing type direct current arrester group operating scheme meets live arrester needs
It asks.The utility model is suitable for HVDC converter substation dc circuit breaker arrester and DC bus arrester；
2, the utility model fusing type direct current arrester group takes more parallel running schemes of multicolumn, straight in single-column fusing type
The fuse for the prior fault column that stream lightning arrester characteristic failure breakdown and structure are not destroyed can fuse automatically, and single-column fusing type direct current is kept away
It fuses when thunder device failure punctures and is isolated with whole group arrester automatically, remaining direct current arrester group can continue to run, and guarantee direct current
System is not latched, and improves DC transmission system reliability.
Detailed description of the invention
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:
Fig. 1 is the schematic diagram of single-column fusing type direct current arrester；
Fig. 2 is the main view of single branch arrester；
Fig. 3 is the cross-sectional view of single branch arrester；
Fig. 4 is the structural schematic diagram of single branch arrester.
Specific embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, now control attached drawing is detailed
Illustrate specific embodiment of the present utility model.
As shown in Figure 1, the utility model high-voltage fuse type direct current arrester includes single-column fusing type direct current arrester 1, it is single
Column fusing type direct current arrester 1 is connected in series by zinc oxide valve plate unit 3 and fuse 2, zinc oxide valve plate unit 3 and fuse
2 form single-column fusing type direct current arrester 1 after epoxy cylinder encapsulates.
Valve block unit 3 is formed after the crimping of Zinc-Oxide Arrester valve block mucilage binding, is placed under single-column fusing type direct current arrester 1
Side, to ensure that single-column arrester steadily of centre of gravity, fuse 2 are placed in 1 top of single-column fusing type direct current arrester.
