Abstract
The utility model relates to an indoor high voltage grounding switch which is mainly composed of a base seat, a grounding knife switch, a static contact, a sensor, a main shaft, a spring and a guide part. The indoor high voltage grounding switch is characterized in that the static contact is a transverse Z-shaped copper bus bar, and one end of the copper bus bar is fixed at the front end of the grounding knife switch, and is connected with the sensor through a steel support. The indoor high voltage grounding switch adopts the advanced processing process to manufacture the static contact, the spring and the guide part are respectively formed by processing plastic parts and steel parts, and the indoor high voltage grounding switch has the advantages of copper material conservation, compact volume, simple processing process, lower cost, good product density, imporosity and good mechanical strength.
Description
Technical field
The utility model relates to a kind of earthed switch, particularly relate to a kind of indoor hv earthing switch, it is improvement to existing earthed switch structure, belong to the earthed switch manufacturing technology, be applicable to the interior and supporting use of the high switch cubicle of each model of electric power system of indoor 3～12kV three-phase alternating current 50Hz, earthy when also can be used as the high-voltage electrical equipment maintenance.
Background technology
At present, the contact of existing earthed switch (for example JN15-12 type indoor hv earthing switch) is a T type copper casting, the ubiquity volume is big, materials are many, the processing technology relative complex, cost of manufacture is higher and easily go out the shortcoming of sand holes, especially the fixing guiding that reaches of spring adopts working of plastics, and the mechanical strength of product is relatively poor.
The utility model content
The purpose of this utility model just is to overcome the prior art above shortcomings, provide a kind of indoor hv earthing switch, this novel indoor hv earthing switch adopts advanced processing technology to make fixed contact, and spring is fixing and guiding adopts working of plastics to adopt the steel part machine to add to form, have the copper of saving material, volume is small and exquisite, processing technology is simple, cost is lower, good, the no sand holes of the density of product and the good characteristics of mechanical strength.
The technical solution that the utility model provides is: this indoor hv earthing switch, mainly by base, ground connection plug-in strip, fixed contact, transducer, main shaft, spring and guide are formed, be characterized in that described fixed contact is the Z font copper busbar of traverse, one end of this copper busbar is fixed on the front end of ground connection plug-in strip, and is connected with transducer by steel bracket.
Other structure of the present utility model is same as the prior art.
Compared with prior art, the beneficial effects of the utility model are: adopt advanced processing technology to make fixed contact, and spring is fixing and guiding adopts working of plastics to adopt the steel part machine to add to form, have the copper of saving material, volume is small and exquisite, processing technology is simple, cost is lower, good, the no sand holes of the density of product and the good characteristics of mechanical strength.
Description of drawings
Accompanying drawing is the structural representation of the embodiment that provides of the utility model.
Embodiment
Below in conjunction with embodiment concrete technical scheme of the present utility model is described further:
As shown in the figure, this indoor hv earthing switch, mainly by base 4, ground connection plug-in strip 2, fixed contact 1, transducer 5, main shaft 6, spring and guide 3 are formed, the Z font copper busbar that described fixed contact 1 is a traverse, one end of this copper busbar is fixed on the front end of ground connection plug-in strip 2, and is connected with transducer 5 by steel bracket 7.
When the operation operating mechanism closes a floodgate this indoor hv earthing switch, force distance makes main shaft overcome the resistance distance, driving connecting lever rotates along the combined floodgate direction, and make the joystick on the ground connection plug-in strip 2 pass through the dead point, spring and guide 3 release energy, and earthed switch are closed a floodgate fast, at closing position, ground connection plug-in strip 2 on the disconnecting link assembly contacts with fixed contact 1 by spring and guide 3 solid and reliablely, makes system earth.
