Abstract
The upper outlet terminal of a kind of pole of the utility model, its structure is upper outlet terminal (1) is profile of tooth occlusal contact condition face (2) with vacuum interrupter contact site, effectively increase conductive contact area between outlet terminal and vacuum interrupter like this, 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.
Description
Technical field
The utility model relates to the upper outlet terminal of the pole in a kind of electrical power distribution system.
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
The utility model proposes a kind of upper outlet terminal of pole, its object is intended to the above-mentioned defect overcome existing for prior art, has larger conductive contact area.
The technical solution of the utility model is: the upper outlet terminal of pole, its structure be upper outlet terminal and vacuum interrupter contact-making surface between be profile of tooth occlusal contact condition face.
Advantage of the present utility model: on pole, the contact-making surface of outlet terminal and vacuum interrupter adopts profile of tooth occlusal contact condition face, the contact area between upper outlet terminal and vacuum interrupter 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 the structural representation of outlet terminal on the utility model pole.
Fig. 2 is upward view embodiment illustrated in fig. 1.
In figure 1 is upper outlet terminal, 2 is profile of tooth occlusal contact condition faces.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the upper outlet terminal of pole, its structure is upper outlet terminal and vacuum interrupter contact site is profile of tooth occlusal contact condition face, effectively increase conductive contact area between outlet terminal and vacuum interrupter like this, 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.
Claims (1)
1. outlet terminal on pole, is characterized in that it being profile of tooth occlusal contact condition face (2) between outlet terminal (1) and vacuum interrupter.
