Abstract
The invention relates to a connection structure and method of a vacuum interrupter and an upper outgoing terminal of a solid-sealed polar pole. The connection structure is characterized in that a toothed meshing contact joint is provided between the vacuum interrupter and the upper outgoing terminal. The connection method is characterized in that the vacuum interrupter and the upper outgoing terminal are in tooth-meshing contact. The connection structure and method has the advantages that conducive contact area of the vacuum interrupter and the upper outgoing terminal is effectively enlarged, conductive loop resistance is reduced, conductive current carrying capacity is increased, high temperature rise allowance is ensured for the solid-sealed polar pole in actual use, the service life of a vacuum breaker is prolonged, and electrical performance of the vacuum breaker is guaranteed.
Description
Technical field
What the present invention relates to is syndeton and the connected mode of a kind of vacuum interrupter for the pole in electrical power distribution system and upper outlet terminal.
Background technology
Pole adopts epoxy resin as dielectric, epoxy resin is utilized the current carrying element such as vacuum circuit-breaker primary conductive partial vacuum arc control device and upper lower wire end to be all sealed to one, make the state of insulation of vacuum interrupter completely not by the impact of external environment, improve environment resistant.But also there is following problem in pole in application process: the contact-making surface of vacuum interrupter and upper outlet terminal adopts flat surface contact manner, easily cause contact insufficient, and then cause galvanic circle contact resistance larger, reduce the ampacity of galvanic circle, when in running, because electric field action easily produces heating, and then cause temperature rise value too high, easily cause security incident, because switchgear guarantee when serious, even have influence on personal security etc.
Summary of the invention
What the present invention proposed is a kind of vacuum interrupter of pole and the syndeton of upper outlet terminal and connected mode, its object is to the above-mentioned defect overcome existing for prior art.
Technical solution of the present invention: pole vacuum interrupter and upper outlet terminal syndeton, it is characterized in that it being profile of tooth occlusal contact condition face between pole vacuum interrupter and upper outlet terminal, its connected mode is profile of tooth occlusal contact condition between pole vacuum interrupter and upper outlet terminal.
Advantage of the present invention: the contact-making surface between vacuum interrupter and upper outlet terminal adopts profile of tooth occlusal contact condition face, contact area between the two can be increased like this, and then reduce galvanic circle resistance, improve galvanic circle ampacity, ensure that pole has larger temperature rise surplus in actual applications simultaneously.
Accompanying drawing explanation
Fig. 1 is pole vacuum interrupter of the present invention and upper outlet terminal syndeton and connected mode schematic diagram.
In figure 1 is upper outlet terminal, 2 are vacuum interrupters, 3 is profile of tooth occlusal contact condition faces.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, pole vacuum interrupter and upper outlet terminal syndeton, it is characterized in that it being profile of tooth occlusal contact condition face between pole vacuum interrupter 2 and upper outlet terminal 1, its connected mode is profile of tooth occlusal contact condition between pole vacuum interrupter 2 and upper outlet terminal 1.
Described vacuum interrupter 2 is the contact-making surfaces of the vacuum interrupter adopting a kind of pole, upper outlet terminal 1 is the contact-making surface of the upper outlet terminal adopting a kind of pole, such connected mode increases conductive contact area between the two, and then reduce galvanic circle resistance, improve conduction ampacity, and in practical application, ensure that pole has larger temperature rise surplus, improve the useful life of vacuum circuit-breaker and ensure that the electric property of vacuum circuit-breaker.
The contact of the existing vacuum interrupter of pole and existing upper outlet terminal is plane contact.
Claims (2)
1. pole vacuum interrupter and upper outlet terminal syndeton, is characterized in that it being profile of tooth occlusal contact condition face between pole vacuum interrupter and upper outlet terminal.
2. pole vacuum interrupter as claimed in claim 1 and upper outlet terminal connected mode, is characterized in that being profile of tooth occlusal contact condition between pole vacuum interrupter and upper outlet terminal.
