Description
Technical field
The present invention relates to a kind of switch, is a kind of composite type earthed switch specifically.
Background technology
Development along with power construction; Electrical network is in continuous expansion, and capacity takes up an area of in order to reduce the transmission of electricity corridor also in continuous increase; The parallel aerial high-voltage power transmission line in common-tower double-return road day by day increases, and some high voltage ground switch that in this transmission line, uses requires to have the ability of opening and closing induction current.Along with the rising with electric pressure of popularizing of common-tower double-return line, the ability of earthed switch opening and closing induction current is also required increasingly high, opening and closing induction current becomes a kind of special service conditions of high voltage ground switch.Earthed switch is mainly used in the maintenance of equipment, in order to prevent to send a telegram here suddenly in the maintenance process, during interruption maintenance; In order to protect operating personnel; Equipment, the safety of system will be outlet through the earthed switch shorted to earth; Discharge fully, can not cause like this by misdelivery electricity or the anti-electric shock accidents that send electricity to cause of circuit; Therefore must be with the two ends of repair apparatus ground connection all.The earthed switch of high voltage power distributing cabinet; Be generally output load side joint ground, when our examination and repair for high-pressure power distribution cabinet load side (as: fastening bolt, dismounting cable etc.), will section breaker; The earthed switch of power distribution cabinet simultaneously closes; Can preventing like this that suddenly incoming call causes can drain residual charge by electric shock accidents in addition, helps maintenance safety.But the structure of existing earthed switch is bigger, therefore is unfavorable for installing.
Summary of the invention
Goal of the invention:, the objective of the invention is for a kind of composite type earthed switch of installing rational in infrastructure, convenient is provided in order to overcome the deficiency that exists in the prior art.
Technical scheme: for realizing above-mentioned technical problem; The technical scheme that the present invention adopts is: a kind of composite type earthed switch; Comprise platform, base, operating axis, conductive shaft, transmission device, platform is fixedly connected with base, and three insulators that are arranged in a linear are installed on platform; Top at each insulator is equipped with fixed contact, and the bottom of each insulator is fixed on the platform; Said operating axis is arranged on the base and is parallel with platform; On conductive shaft, be provided with three and the corresponding moving contact in fixed contact position, be connected with earth lead at the two ends of conductive shaft; Said transmission device comprises connecting rod, spring, drive joint, support, and spring is rack-mount, and drive joint is installed on the operating axis, and an end of support is fixed on the base, the other end and drive joint are fixed; Conductive shaft is connected with drive joint through connecting rod; Moving contact contacts with fixed contact during combined floodgate.
The bottom surface of said platform and the bottom surface of base are at grade.
Beneficial effect: compared with prior art, advantage of the present invention is rational in infrastructure, the convenient installation.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
As depicted in figs. 1 and 2; A kind of composite type earthed switch of the present invention; Comprise platform 1, base 2, operating axis 3, conductive shaft 4, transmission device, platform 1 is fixedly connected with base 2, and three insulators that are arranged in a linear 5 are installed on platform 1; On the top of each insulator 5 fixed contact 6 is installed, the bottom of each insulator 5 is fixed on the platform 1; Said operating axis 3 is arranged on the base 2 and is parallel with platform 1, the right-hand member protuberate basic unit 2 of operating axis 3; On conductive shaft 4, be provided with three and the corresponding moving contact 7 in fixed contact 6 positions, be connected with earth lead 8 at the two ends of conductive shaft 4; Said transmission device comprises connecting rod, spring 9, drive joint 10, support 11, and spring 9 is installed on the support 11, and drive joint 10 is installed on the operating axis 3, and an end of support 11 is fixed on the base 2, the other end and drive joint 10 is fixing; Conductive shaft 4 is connected with drive joint 10 through connecting rod; Moving contact 7 contacts with fixed contact 6 during combined floodgate.
Operation principle: when being rotated counterclockwise operating axis 3, conductive shaft 4 also is rotated counterclockwise under the drive of operating axis 3, and moving contact 7 was opened with fixed contact in 6 minutes like this; When the operating axis 3 that turns clockwise, conductive shaft 4 also turns clockwise under the drive of operating axis 3, and moving contact 7 contacts with fixed contact 6 like this, promptly closes a floodgate.
The bottom surface of the bottom surface of platform 1 and base 2 preferably at grade among the present invention.The external part of operating axis 3 can be a left end also among the present invention, and perhaps all stretch out at two ends.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
