Abstract
The utility model discloses a kind of pole for medium voltage breaker, including housing, the upper contact arm terminals being coated in the housing and lower contact arm terminals and the vacuum interrupter being arranged between the upper contact arm terminals and lower contact arm terminals in housing, die opening between the upper contact arm terminals and lower contact arm terminals is arranged more than or equal to 270mm, less than or equal to 280mm.With this structure design, the setting of vacuum interrupter and die opening can be passed through, effectively overcome sealing (integrated) formula electrode column of vacuum arc extinguishing chamber, and the deficiency existing for VTN vacuum circuit breakers, this utility model exterior insulation performance is good, and stable mechanical performance, internal electric field are evenly distributed and anti-filthy ability is strong.
Description
Technical field
This utility model is related to Medium Voltage Switchgear technical field, more particularly to a kind of sealing pole for medium voltage breaker
Post.
Background technology
Under prior art, the indoor armoured system 3.6KV～12KV tri- of KYN28-12 types intersects
Stream 50HZ single busbars and bus sectional lized complexes, are mainly used in power plant, medium and small generator power transmission, industrial and mineral enterprises and institutions list
Press off in the .KYN28-12 such as the startup by electricity, power transmission and large high-voltage motor of secondary substation of position distribution and electric industry system
Closing needs outside offer power switch when cabinet runs, control power supply, protect the buses such as power supply, alternating current power supply, busbar voltage, while
Also to buses such as external output signal such as trouble-signal, anticipating signals, generally these buses are little by high-tension switch cabinet cabinet top
The bus clip that bus-bar room is installed, between cabinet and cabinet, connection cable is realizing.Traditional little bus connected mode, adjacent two bus
After 1 sequence, reusing appts 4 are fixedly connected.But such attachment structure can cause problems with：1. joint heating, pine
Dynamic virtual connection, conductive resistance are big and current loss is big, waste electric energy.2 little bus-bar room limited spaces, the installation number of little bus are subject to
Limit, it is general no more than 22 sections.Between 3 cabinets, little bus cable cannot complete to install in manufacturer, increase cost of transportation.4 is existing
When little bus is installed in field, workmen will climb up cabinet top, install connection cable by root, install and safeguard inconvenience, there is safety hidden
Suffer from.In view of the foregoing.There is provided a kind of new switch cubicle little bus connecting device.
Utility model content
The purpose of this utility model is that a kind of exterior insulation performance of offer is good, stable mechanical performance, internal electric field distribution
The strong pole of uniform and anti-filthy ability.
It is that, up to this purpose, this utility model is employed the following technical solutions：
A kind of pole for medium voltage breaker, including housing, the upper contact arm terminals being coated in the housing
And lower contact arm terminals and the vacuum extinction being arranged between the upper contact arm terminals and lower contact arm terminals in housing
Room, the die opening between the upper contact arm terminals and lower contact arm terminals are arranged more than or equal to 270mm, less than or equal to 280mm.
Wherein, the pole also includes being arranged at the insulated tension pole below the vacuum interrupter in housing.
Wherein, it is copper between the lower end of the vacuum interrupter and the lower contact arm terminals to be flexible coupling.
Wherein, the distance between the stomidium axis of the lower contact arm terminals and lower surface of the housing are more than or equal to
160mm, less than or equal to 170mm.
Wherein, the housing adopts mixture of epoxy resins integrated injection molding.
The beneficial effects of the utility model：This utility model includes housing, the upper contact arm wiring being coated in the housing
End and lower contact arm terminals and the vacuum extinction being arranged between the upper contact arm terminals and lower contact arm terminals in housing
Room, the die opening between the upper contact arm terminals and lower contact arm terminals are arranged more than or equal to 270mm, less than or equal to 280mm.
With this structure design, the setting of vacuum interrupter and die opening can be passed through, sealing (integrated) formula vacuum interrupter is effectively overcome
Pole, and the deficiency existing for VTN vacuum circuit breakers, this utility model exterior insulation performance are good, stable mechanical performance, inside
Electric Field Distribution is uniform and anti-filthy ability is strong.
Description of the drawings
Fig. 1 is a kind of structural representation of the pole for medium voltage breaker of this utility model.
Specific embodiment
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings and by specific embodiment.
As shown in figure 1, a kind of pole for medium voltage breaker in the present embodiment, including housing 1, be coated on it is described
Upper contact arm terminals 2 and lower contact arm terminals 3 in housing 1, and it is arranged at the upper contact arm terminals 2 and lower contact arm wiring
Vacuum interrupter 4 between end 3 in housing 1, the die opening between the upper contact arm terminals 2 and lower contact arm terminals 3 are arranged
More than or equal to 270mm, less than or equal to 280mm.Preferred 275mm in the present embodiment.
Specifically, the present embodiment pole also includes that the insulation being arranged in 4 lower section housing 1 of the vacuum interrupter is drawn
Bar 5.It is copper between the lower end of the vacuum interrupter 4 and the lower contact arm terminals 3 to be flexible coupling, specifically, herein using copper
Piece 6 connects, and designs in this way so that contact resistance is little, simple structure, reliable and stable, service life overlength.
In the present embodiment, the stomidium axis of the lower contact arm terminals 3 is big with the distance between the lower surface of the housing 1
In equal to 160mm, less than or equal to 170mm.It is preferred that 165mm.
The housing 1 adopts mixture of epoxy resins integrated injection molding.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and the restriction to this utility model protection domain can not be construed to by any way.Based on explanation herein,
Those skilled in the art associates other specific embodiments of the present utility model by need not paying performing creative labour,
These modes are fallen within protection domain of the present utility model.
