Abstract
The utility model discloses an outdoor high pressure isolation switch operator arc striking device having good commonality, and the structure comprises pedestal. The outdoor high pressure isolation switch operator arc initialling device is characterized in that an elastic component and a movable shaft are arranged above the pedestal; the upper end of the movable end is provided with an arc striking contact; one end of the elastic component is fixed with the pedestal, and the other end withstands the arc striking contact; and the arc striking contact is provided with a lead. The arc striking device is safe and reliable, has good commonality, can be used on a vertical type outdoor high pressure isolation switch, and also can be used on double column level centre fracture and three column type double fracture outdoor high pressure isolation switches.
Description
Technical field
The utility model relates to a kind of outdoor high-voltage isolating switch, relates in particular to a kind of operator arc-initiating device of outdoor high-voltage isolating switch.
Background technology
Known have nothing in common with each other at the operator striking contact of the various outdoor high-voltage isolating switchs of usefulness at present.At present, vertical folding-jib substantially all is to adopt arc-initiating device is put on its guide plate, in the side that guide plate contacts with fixed contact the striking contact is installed, and the arc-initiating device of this mode is waste material relatively, and can only be used for rectilinear contact; The horizontal twin columns center most of used arc-initiating devices of fracture are a kind of simple contact contacts, clamp by spring.The failure rate of this arc-initiating device is than higher, and the material materials are bigger, and does not have versatility.In sum, current arc-initiating device structure is still waiting to improve.
Summary of the invention
The utility model is poor at arc-initiating device versatility in the prior art, the high deficiency of failure rate, provide a kind of by good with property, safe and reliable outdoor high-voltage isolating switch operator arc-initiating device, this arc-initiating device not only can use on rectilinear outdoor high-voltage isolating switch, can be used in equally on twin columns horizontal center fracture and the three pillar type double break mouth outdoor high-voltage isolating switch.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of outdoor high-voltage isolating switch operator arc-initiating device, comprise pedestal, its main points are, described pedestal top is provided with elastic parts, movable axis, described movable axis upper end is provided with the striking contact, described elastic parts one end and pedestal are fixed, and the other end withstands the striking contact, and described striking contact is provided with lead.
In the technique scheme, described striking contact is provided with 2 layers.
In the technique scheme, pedestal is provided with the installing hole more than 2 or 2.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
1) this arc-initiating device not only can use on rectilinear outdoor high-voltage isolating switch by good with property, can be used in equally on twin columns horizontal center fracture and the three pillar type double break mouth outdoor high-voltage isolating switch.
2) the operator arc-initiating device is safe and reliable, has solved the problem of unstable of arc-initiating device in the prior art.
3) the utility model is simple in structure, and is convenient for production, can save wide variety of materials simultaneously.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Referring to Fig. 1～Fig. 3, formations such as the main pedestal 2 of outdoor high-voltage isolating switch operator arc-initiating device, striking contact 1, elastic parts 3.
Described pedestal 2 tops are provided with elastic parts 3, movable axis 4, and described movable axis 4 upper ends are provided with striking contact 1, and described elastic parts 3 one ends and pedestal 2 are fixing, the other end withstands striking contact 1, described striking contact 1 is provided with lead 5, and as preferably, described elastic parts 3 is a spring.
As preferably, described striking contact 1 is provided with 2 layers, and one deck is a body, and another layer is the contact contact-making surface, and described contact contact-making surface adopts high performance metal material CuW alloy.
See Fig. 4, described pedestal 2 is provided with a plurality of installing holes 6, can be fit to the application of various static contact isolation switches, comprises the horizontal center of vertical folding-jib, the twin columns fracture of 110kV, 220kV, the outdoor high-voltage isolating switch of the horizontal double break mouth structure of three posts.
During installation,, according to actual needs, select installing hole wherein, arc-initiating device is installed on the stationary contact headstock, and lead 5 is installed on the fixed contact by a plurality of installing holes 6 that are provided with on the pedestal 2.
Its principle is; when moving contact when fixed contact closes a floodgate; at first moving contact contacts with arc-initiating device; can alleviate moving contact directly contacts with fixed contact; the electric arc that moment produces is to the destruction of fixed contact, when moving contact with after arc-initiating device contacts, the moving contact continuation is closed a floodgate to fixed contact; effectively protected fixed contact because the electric arc of moving contact and the generation of fixed contact moment has dropped to minimumly this moment.
Though the utility model is described by preferred embodiment, yet the utility model is not limited to embodiment as described herein, also comprises various changes and the variation done under the situation that does not break away from the utility model scope.
