The connecting conducting rod used for the 126 KV total box combined electric appliance power frequency withstand voltage experiment comprises conductors, a front joint, a back joint and a connecting block. The conductors are two circular pipes, and plug screws are arranged at the two ends in the conductors, are annular blocks of which the outer circles and inner holes are all screw threads, are connected with the conductors via the screw threads on the outer circles, and are equipped with vent holes. The connecting block is equipped with two stepped holes used for connection, bolts are arranged in the stepped holes, and the two conductors are arranged at the two sides of the connecting block respectively and are connected with the bolts via the plug screws; the outer end of one conductor is in threaded connection with the front joint, the outer end of the other conductor is in threaded connection with the back joint, and the front and back joints are both equipped with through holes communicated with the conductors. The connecting conducting rod used for the 126 KV total box combined electric appliance power frequency withstand voltage experiment of the utility model has the characteristics of being simple and reasonable in structure and low in cost, and being convenient to assemble, operate and process.
Description
Technical field
The utility model relates to a kind of SF6 combined electrical apparatus technical field, and specifically a kind of 126kV is total to the experiment of case combined electrical apparatus industrial frequency withstand voltage with connecting conducting rod.
Background technology
The SF6 combined electrical apparatus with its compactness, floor area is little and reliable and be widely used in present power plant construction.And SF6 gas is good and be widely used in gas insulated metal enclosed swit chgear with its insulating property, but when combined electrical apparatus inside existed wedge angle, burr, its insulating property can sharply reduce.Due to colliding with in part processing and transportation assembling process, can there be the wedge angle burr in the SF6 combined electrical apparatus unavoidably in assembling process, due to the defective of making assembling, if when combined electrical apparatus dispatches from the factory, do not carry out pressure test, might cause the scene withstand voltage defective, have quality problems.Therefore, when manufacturer dispatches from the factory at combined electrical apparatus, should carry out power frequency withstand test.
When the common case combined electrical apparatus of 126kV carries out industrial frequency withstand voltage, conducting rod one end need to be connected with disc insulator, the other end is connected with the withstand voltage frock of experiment use, form, be the monoblock type tubulose structure of zigzag for casting due to traditional conducting rod, cause its assembly connection to be inconvenient to operate, waste time and energy, the conducting rod difficulty of processing is large in addition, and cost is high.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure in order to overcome defects, is convenient to assembly manipulation, and the 126kV of being convenient to process is case combined electrical apparatus industrial frequency withstand voltage experiment connection conducting rod altogether.
The technical solution adopted in the utility model is: a kind of 126kV is case combined electrical apparatus industrial frequency withstand voltage experiment connection conducting rod altogether, it is characterized in that: comprise conductor, front connector, rear joint and contiguous block, conductor is two pipes, two ends in conductor bores are provided with plug screw, plug screw is the ring block that cylindrical and endoporus are screw thread, plug screw is connected with conductor by the screw thread on cylindrical, is provided with air hole on plug screw; Be provided with two stepped holes that are used for connection on described contiguous block, bolt is set in stepped hole, two conductors are separately positioned on the both sides of contiguous block and are connected with bolt by plug screw, the outer end of a conductor with front connector for being threaded, the outer end of another root conductor is connected with rear joint screw thread, is provided with the through hole that is communicated with conductor on front connector and rear joint.
Front connector be connected the inside of joint and also be connected with plug screw in conductor by bolt.
The utility model is split-type structural with traditional integral cast type architecture advances, formed by two conductors, contiguous block and forward and backward joint, two conductor dbus are crossed plug screw and bolt and are separately positioned on contiguous block both sides, connect respectively again forward and backward joint in the outer end of two conductors.Two conductors are split-type structural, can adjust its position angle, and the conducting rod of this structure is when assembling, and flexible operation conveniently connects, and split type structure also is convenient to make processing, reduces costs.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Now by reference to the accompanying drawings the utility model is further described, the technical solution adopted in the utility model is: a kind of 126kV is case combined electrical apparatus industrial frequency withstand voltage experiment connection conducting rod altogether, comprise conductor 6, front connector 1, rear joint 13 and contiguous block 7 etc., conductor 6 is two pipes, two ends in conductor 6 holes are provided with plug screw 5, and plug screw 5 is the ring block of screw thread for cylindrical and endoporus.Plug screw 5 is connected with conductor 6 by the screw thread on cylindrical, is provided with air hole on plug screw 5.Be provided with two stepped holes that are used for connection on described contiguous block 7, bolt is set in stepped hole, usually the position of stepped hole macropore is oppositely arranged, be positioned at the left side of contiguous block 7 as a macropore, another macropore is positioned at the right side of contiguous block 7, macropore can conveniently be placed the head of bolt, the prominent small holes of bar section of bolt.Two conductors 6 are separately positioned on the both sides of contiguous block 7 and are connected with bolt by plug screw 5.The outer end of a conductor 6 namely away from that end of contiguous block 7 with front connector 1 for being threaded, the outer end of another root conductor 6 is threaded with rear joint 13, is provided with the through hole that is communicated with conductor 6 on front connector 1 and rear joint 13.Front connector 1 is connected with the disc insulator of combined electrical apparatus, and rear joint 13 is connected with withstand voltage test fixture.The utility model can also front connector 1 be connected the inside of joint 13 and also be connected with plug screw 5 in conductor 6 by bolt, can make so forward and backward joint be connected more firm with conductor 6.
Because the utility model is split-type structural with traditional integral cast type architecture advances, with disc insulator be connected test fixture when being connected, can adjust flexibly the position, be convenient to attended operation, time saving and energy saving, increase work efficiency; Split type structure also is convenient to make processing in addition, reduces costs.
The utlity model has simple and reasonable for structurely, cost is low, is convenient to assembly manipulation, the characteristics of being convenient to process.
