The high voltage isolation switch operation connecting rod is advantageous in that the isolation switch operation connecting rod adopts a solid integral round steel as the connecting rod; one end of the isolation switch operation connecting rod is directly connected with a connecting bulb of the hand-operated mechanism, and the other end is directly connected with a connecting bulb of the high voltage isolation switch. The high voltage isolation switch operation connecting rod is advantageous in that by using the solid round steel as the connecting rod, the middle connecting joint can be saved, and the connecting rod can be directly inserted in the connecting bulbs of the isolation switch and the hand-operated operation mechanism, therefore the strength and the rigidity of the integral connection rod can be greatly improved.
Description
Technical field
The utility model relates to a kind of operating means of electric device, and the high voltage isolator that refers in particular to a kind of high-low pressure cabinet is operatively connected bar, is mainly used in the high voltage isolator operation of high and low voltage switch cabinet.
Background technology
Along with the development of electrified process, adopt the place of electrical control or driving more and more, the list-directed place of the electronics of bringing thus is more and more, and the instrument of control automatically is also more and more; High voltage isolator is a kind of common electric control elements in the electric meter control, it is 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 off, 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; Be divided into by the infield difference, formula outside formula and the room is divided into by the insulation column number within doors, open side type, and queen post and three pillar type, each electric pressure has optional equipment.High voltage isolator also can be isolated the part that needs in the high voltage distribution installation to have a power failure with live part reliably, to guarantee the safety of service work.The contact of high voltage isolator is all open in air, has tangible cut-off point, isolating switch does not have arc-control device, therefore can not be used for cutting off load current or short circuit current, otherwise under the high pressure effect, cut-off point will produce strong electric arc, and be difficult to from horizontal blanking, even may cause arcing (relatively or phase fault), scaling loss equipment, jeopardize personal safety, the serious accident that Here it is so-called " on-load draws isolating switch ".High voltage isolator can also be used to carrying out the handover operation of some circuit, to change the operational mode of system.For example: in the double-bus circuit, can operating circuit be switched on another bus from a bus with high voltage isolator.
High voltage isolator divides outdoor version and indoor type, and outdoor version comprises single-pole switch and three-pole isolator, is commonly used for first isolating switch that opens circuit that supply line and user are separated; Indoor type often is connected in series with primary cut-out, and supporting use is with the reliability that guarantees to have a power failure.In addition, in the complete power distribution equipment of high pressure, isolating switch is commonly used for voltage transformer, lightning arrester, the high voltage control electrical equipment of distribution house transformer and metering cabinet.
Isolating switch all is furnished with the hand-power operating mechanism, and existing manual-operating mechanism generally adopts CS6-1 type manual-operating mechanism.Whether will extract alignment pin earlier during this operation, the divide-shut brake action wants resolute, rapidly, notices at the end and can not overexert that end of operation must be used the alignment pin pinning, and estimate its moving contact position and meet the requirements.During with insulating bar operation single-pole isolator, combined floodgate should close the both sides phase earlier, after close middle phase; During separating brake, order in contrast.Therefore there is complicated operation, and the easy problem of damaging, the bar that is operatively connected of especially existing manual-operating mechanism generally adopts steel pipe manufacturing, and need connect by a transition joint, very influenced for the bulk strength of connecting rod like this, therefore still be necessary this is further improved.
The utility model content
The purpose of this utility model is that at the existing deficiency of existing high voltage isolator, it is higher to propose a kind of intensity, does not allow flimsy high voltage isolator to be operatively connected bar.
For realizing the purpose of this utility model, the implementer's case that proposes is: a kind of high voltage isolator is operatively connected bar, comprise high voltage isolator, isolator operation connecting rod and manual-operating mechanism, it is characterized in that, described isolator operation connecting rod adopts solid whole round steel as connecting rod, one of isolator operation connecting rod directly connects with the connection bulb that is connected manual-operating mechanism, and the other end also directly connects with the connection bulb that is connected high voltage isolator.
Further, described isolator operation connecting rod and the connection bulb that is connected manual-operating mechanism connect directly by being threaded, and described other end is also directly by screw thread and the connection bulb connection that is connected high voltage isolator;
Further, described connection bulb has one section to be the attaching nut, and the termination of described isolator operation connecting rod has one section to be connecting screw rod, and the connecting screw rod of isolator operation connecting rod directly screws in the attaching nut who connects bulb;
Further, described isolator operation connecting rod connects by being welded to connect with the connection bulb that is connected manual-operating mechanism, and described other end also directly connects with the connection bulb that is connected high voltage isolator by welding;
Further, described connection bulb has one section to be connecting hole, the termination of described isolator operation connecting rod has one section to be insertion rod, and the insertion rod of isolator operation connecting rod is got up in the port annular solder directly screw in the connecting hole that connects bulb with interference fit after again.
Advantage of the present utility model is: by adopting solid round steel as connecting rod, and jointing in the middle of saving, directly connecting rod is inserted being connected in the bulb of isolating switch and manual-operating mechanism both sides, make the bulk strength of connecting rod and rigidity all be significantly improved.
