Abstract
The utility model discloses a novel grounding switch accessorily mounted on a high voltage isolation switch, comprising an isolation switch body and a grounding switch accessorily mounted on the isolation switch, wherein the grounding switch comprises a couple axle, the couple axle is a square tubular axle, the couple axle is equipped with a transmission crank arm, an interlock plate and a grounding pole carriage, and the grounding pole carriage is fixedly provided with a grounding pole through a bolt. The novel grounding switch accessorily mounted on a high voltage isolation switch is very convenient in manufacture processing and mounting debugging, etc., and enables the production efficiency and the product reliability to be increased. The grounding side of the isolation switch can be exchanged at will according to the requirement of the construction site, i.e., the grounding switch accessorily mounted on the isolation switch can be flexibly exchanged from left to right or from right to left, and because of the combination structure, it is very convenient for adjustment and easy to realize user demands.
Description
Technical field
The utility model relates to the novel grounded switch that a kind of high voltage isolator attaches dress, and earthed switch is the equipment of using as the ground protection personal security in the middle of the power transmission and transforming equipment.
Background technology
High voltage isolator is an important device for switching in power plant and the transformer station's electrical system; Need and the supporting use of primary cut-out; Its major function is: guarantee High-Voltage Electrical Appliances and the safety of device when service work, play isolation voltage, can not with cut-out, drop into load current and cut-off short circuit current; Only can be used for not producing some handover operation of powerful electric arc, that is to say that it does not have the arc extinguishing function.
The earthed switch that high voltage isolator attaches dress has a variety of, mainly by ground connection fingertip, ground connection moving contact, conducting rod, gangbar, levels operation connecting rod, vertical operation connecting rod, form with interlock, the operating mechanism of isolating switch.When needs actuating isolating switch, the isolating switch separating brake, after separating brake put in place, the interlock of isolating switch and earthed switch was opened, and at this moment earthed switch can be operated.The operating mechanism of actuating earthed switch; Make the conducting rod of earthed switch reach the top moving contact of installing under the drive of each gangbar; Combine with the ground connection fingertip, at this moment, the earthed switch that isolating switch attaches dress just is grounded; The miscellaneous equipment that is connected with isolating switch has also been realized ground protection, and interlock has guaranteed that also isolating switch itself can not close a floodgate simultaneously.
General earthed switch is at the construction field (site) during Installation and Debugging, because structural reason, installs, assembling, adjustment be all cumbersome, influences construction schedule and performance of products.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art; Provide a kind of high voltage isolator to attach the novel grounded switch of dress; It is all very convenient at aspects such as manufacturing processing, Installation and Debugging, has improved production efficiency and reliability of products.Can be according to the needs of job site, the ground connection side of conversion isolating switch is arbitrarily exchanged about promptly the isolating switch earthed switch that attaches dress is realized flexibly, because be combining structure, adjusts very conveniently, is easy to realize customer requirements.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of high voltage isolator to attach the novel grounded switch of dress, comprises the isolating switch body, and isolating switch attaches the earthed switch of dress; Said earthed switch comprises universal driving shaft, and said universal driving shaft is the square tube type axle, is set with transmission crank arm, interlock board and ground connection knife bar carriage on the universal driving shaft, and said ground connection knife bar carriage has the ground connection knife bar through bolt.
Said transmission crank arm, interlock board and ground connection knife bar carriage are installed on the universal driving shaft through fixing fixture block respectively, and said fixedly fixture block is that two " V " type geosynclinal blocks of installing relatively constitute.
The bolt of dead earth knife bar is " U " type bolt on the ground connection knife bar carriage.
The utility model changes the universal driving shaft that isolating switch attaches the earthed switch of dress into square tube by pipe, for realizing flexible rotation, all is that the round turning set of circle makes round outside but spuare inside type into original inside and outside on the support, to adapt to the rotation requirement.The ground connection knife bar carriage of installation and combination position adjustable and angle on the universal driving shaft with bolt ground connection knife bar, according to accurate fingertip position, fixedly steps up ground connection knife bar carriage during adjustment on the ground connection knife bar carriage.
The beneficial effect of the utility model is: the utility model can not add the repacking ground earthed switch that the realization isolating switch attaches dress in the product erecting bed in the exchange of isolating switch and arranged on left and right sides, and easy to adjust.On producing, also original pin is connected complicated technologies such as required welding, boring and remove, improved operating efficiency.
Thereby the utility model is being made processing, and aspects such as Installation and Debugging are all very convenient, improved production efficiency and reliability of products.Can be according to the needs of job site, the ground connection side of conversion isolating switch is arbitrarily exchanged about promptly the isolating switch earthed switch that attaches dress is realized flexibly, because be combining structure, adjusts very conveniently, is easy to realize customer requirements.
