Description
Technical field
This utility model relates to a kind of electric armour clamp, particularly a kind of be applied on HVDC spark gap put a dwell set.
Background technology
Spark gap is for preventing the visual plant of lightning stroke trip in ultra-high-tension power transmission line, the main performance of spark gap is determined by discharging gap group, in specific implementation process, spark gap can be subject to environment, steel tower tower, barrier obstruction, installs and use is subject to many limitations.
Utility model content
The purpose of this utility model is in that: provide one be applied to ± 500kV direct current arrester on discharging gap group, realized by following technical proposals:
One is applied to ± 500kV direct current arrester on discharging gap group, including the first electrode and the second electrode, described first electrode includes the first electrode retaining collar, and the first electrode retaining collar is connected with installing plate by adjusting rod, and installing plate is connected with the support insulator of spark gap；Described second electrode includes the second electrode retaining collar, and the ring holder two ends of the second electrode retaining collar are each provided with one group of conductor spacer assembly and wire group is clamped.
As selection, described conductor spacer assembly includes quadripartion conductor spacer, by quadripartion wire clamp of conductor spacer head, wire group is clamped.
As selection, described conductor spacer assembly also includes jumper wire spacing rod, and wire group is positioned at two wires of diagonal positions and is connected by hank knotting, and hank knotting body is connected with ring holder by jumper wire spacing rod.
As selection, described first electrode retaining collar is arch, and arch convex surface is away from the second electrode retaining collar, and adjusting rod is arranged on arch convex surface by connecting plate.
As selection, described second electrode retaining collar is track type plane, and the ring holder two ends of the second electrode retaining collar are arranged at cambered surface top, track type two ends.
Of the present utility model it is characterized in that:
1. the first electrode retaining collar is connected with support insulator by adjusting rod and installing plate, and the length of adjusting rod can need to regulate voluntarily according to in-site installation.By this improvement, staff is made as required discharging gap of arrester (i.e. distance between first, second electrode retaining collar) to be adjusted, thus adjusting the service behaviour of spark gap.
2. the first electrode retaining collar adopts arch to arrange, and arch convex surface, away from the second electrode retaining collar, makes the space between first, second electrode retaining collar increase, matches with the adjusting rod of the first electrode retaining collar, be easier to avoiding obstacles when zinc oxide surge arresters, expand range of application.
3. the second electrode retaining collar have employed two groups of conductor spacer assemblies wire group clamped, and improves clamping stability.By arranging hank knotting, two wires that wire group diagonal each other is symmetrical are connected between two, whole second electrode is made to become isoelectric level body, the design of two groups of conductor spacer assemblies simultaneously, when ensure that the first electrode arranged above with barrier, second electrode remains to be arranged on above the first electrode, ensure that discharging gap of arrester is stable in normal range of operation, improve the job stability of spark gap.
In sum, the beneficial effects of the utility model are: discharging gap can regulate according to requirements, and are applicable to leaping over obstacles installation, easy for installation, improve job stability and the wide usage of spark gap.
