Abstract

The utility model relates to a rotary high voltage isolated switch which comprises an outer casing, static contacts and a movable rod. The utility model is characterized in that two half rings which are integrally cast by insulation materials are fixed to a support; an upper and a lower intercardinal points on the annular outer casing are fixedly provided with the static contacts; two level intercardinal points are fixed to grounding contacts; the middle part of the movable rod is fixed to an operating shaft which passes through the shaft center of the outer casing; both ends of a conductor which is encapsulated by the movable rod are respectively contacted with the two static contacts and the two grounding contacts; the operating shaft is positioned on the support. Because the outer casing is formed by the casting of insulation materials, the fixation of static contacts can become simple and an insulation problem does not need to be considered; operating shaft can switch on or off for grounding within the rotation angle of 90 DEG. The utility model has the advantages of scientific design, reasonable layout, smaller casing and lighter weight compared with traditional casings besides little space occupation of installation, and the rotary high voltage isolated switch is suitable for use in various circumstances.

Description

The rotating type high-pressure isolating switch

Technical field:

The utility model belongs to electrical field, particularly a kind of rotating type high-pressure isolating switch.

Background technology:

The effect of isolated high-voltage switch is to isolate, connect, changing getting in touch between electrified body and the electrical appliance under the non-loaded state of circuit.Existing isolating switch such as GN30, its fixed contact is fixed on the metal framework of three-dimensional rectangle by the insulator of porcelain or plastic colloid, and its conductor means of moving bar of rotation is on the insulator of porcelain.The consumption metal material is many, it is big, easily broken, heavy to take up space, to installed and used, transportation and product is supporting makes troubles.

Summary of the invention:

The purpose of this utility model is the rotating type high-pressure isolating switch that loop configuration that a kind of shell of design adopts high insulation plastic material to make replaces the traditional vertical quadra.

Technical solutions of the utility model are achieved in that a kind of rotating type high-pressure isolating switch, include shell, fixed contact and moving bar, it is characterized in that shell is formed by two integrated poured semi-circular being fixed on the support of insulating material, the place of quadrantal points up and down of annular outer cover is fixed with fixed contact, level two quadrantal points places are fixed with grounding contact, moving bar middle part is fixed on the actuating axle that passes place, annular outer cover axle center, the conductor two ends that moving bar is sealed can be touched two fixed contacts and two grounding contacts respectively, and the actuating axle is positioned on the support.Because fixed contact and grounding contact are in the same plane of moving bar rotation, the actuating axle of moving bar can be realized switch in 90 ° the anglec of rotation combined floodgate, separating brake and ground connection.

The utlity model has novel, design science, rationally distributed, two semi-rings adopt high-intensity plastic cement integral cast to form, and replace metal framework and insulator, have not only saved material and accessory, and better insulation property are arranged, be fit to various environment and use down.Want with traditional isolating switch that specific volume only is 50%, weight only is 30%.

Description of drawings:

Below in conjunction with concrete legend the utility model is described further:

Fig. 2 rotating type high-pressure isolating switch end face part sectioned view

Embodiment:

With reference to accompanying drawing 1 and Fig. 2, its shell 1 of rotating type high-pressure isolating switch is that the pour mass by upper and lower two semi-circular high-strength insulating material is fixed on the support 2 and forms,

The place of quadrantal points up and down of annular outer cover 1 is fixed with fixed contact 3, the outer end of fixed contact 3 is the turnover line that switch connects, the level two quadrantal points places of shell 1 are fixed with grounding contact 4, moving bar 5 middle parts are fixed on the actuating axle 6 that passes place, annular outer cover 1 axle center, conductor 51 two ends that moving bar 5 is sealed can be touched two fixed contacts 3 and two grounding contacts 4 respectively,

conductor

51 and 6 on actuating axle that moving bar 5 is sealed are cast with insulating material 52, conductor 51 two ends expose, and keep contacting with the good of grounding contact 4 with fixed contact 3.Actuating axle 6 is positioned on the support 2.Annular outer cover 1 both ends of the surface offer transparent form, and are fixed with transparent shrouding 7, and the transparent panel 7 of setting-in had both improved alternate insulation level, can see the action of moving bar 5 and the working condition of contact again.The combined floodgate of 90 ° of realization switches of actuating rotating shaft; 90 ° of separating brakes of then realizing switch of inhour actuating, this moment, the contact of moving bar promptly joined with grounding contact, and the safety of the electrified body on realizing and the circuit of lower end is isolated.

In sum, shell has been adopted the high strength plastics integral cast and has been formed, and no matter is that electrical insulation properties or intensity all meet national standard, but does not also get rid of such as materials such as employing engineering plastics.The shell mechanism of annular, its stressed tangential direction along the garden face, tolerance stress intensity height, the rotation of moving bar cooperates the properest along the garden camber line, the minimum that volume can be done.Certainly, adopt regular polygon or foursquare structure can reach the effect similar too, belong to equivalent, also should belong to the row of the utility model protection to this patent for shell.

Claims
