Background
The transformer and the circuit breaker are main equipment in a power system, a screw rod wiring device is needed for connecting the transformer and the circuit breaker pile head with a wire, the screw rod wiring device has very important functions, is an important component part for connecting the transformer and the circuit breaker pile head with the wire, and has various connection modes at present.
The existing wiring device such as SBT and SBG type transformer wire clamps adopt a threaded hole mode, are connected with a transformer pile head through integral screwing, then lock a locking bolt, and are connected with a wire connecting wire clamp through a pressing plate type or a terminal board to be connected with an equipment wire clamp. The SBW type transformer wire clamp is connected with the pile head in a threaded sleeve mode, and the threaded sleeve is connected with the wire clamp to lock the locking bolt; the transformer pile head is directly connected with the threaded hole; the connection with the wire adopts a bolt to compress the wire. In addition, the C-shaped transformer wire clamp is directly connected with the pile head in a threaded hole mode, and then a wedge block in the wire clamp is used for tightly pressing the threaded hole for fixed connection; when the wedge block is connected with the lead, the fastener is screwed through the wedge block to compress the lead. However, the adoption of the connection modes has the disadvantages of overlong current path, high loss, unstable connection, increased cost and inconvenient installation.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to above-mentioned technical problem, a diplopore parallel mode screw rod termination is provided to make the electric current route between pile head and the wire shorter, reduce the loss, connect firmly, and reduce cost improves the installation convenience.
In order to solve the technical problem, the technical scheme adopted by the utility model is a double-hole parallel screw wiring device, which comprises a device body, wherein two parallel and parallel through holes are arranged on the device body, one of the through holes is a transformer pile head connecting hole, and the other through hole is a wire guide hole; a compaction threaded hole is formed in the side wall of the wire hole, and a torque bolt is arranged in the compaction threaded hole; the torque bolt is used for spirally pressing the lead arranged in the lead hole; and a semicircular arc-shaped internal thread is arranged on the surface of the inner wall of the wire hole opposite to the pressing threaded hole and is used for matching with a torque bolt to clamp a wire in the wire hole.
Two or more pressing threaded holes are formed; the two or more compaction threaded holes are arranged in parallel.
The two pressing threaded holes and the wire guide hole are arranged perpendicularly to each other.
And internal threads are arranged on the inner wall of the transformer pile head connecting hole.
The inner wall of the wire hole can be also provided with longitudinal sawteeth; the wire-connecting device is used for piercing an oxide layer on the surface of a wire, so that the electrical performance contact of the wire-connecting device is good and the grip of the wire-connecting device and the wire is increased.
The device body and the torque bolt are made of high-strength and high-conductivity materials.
During installation, after the connecting hole of the transformer pile head is screwed into the pile head, the nut of the pile head is screwed tightly; and then, the wire penetrates through the wire hole, the torque bolt is adopted to tightly press the wire, and in the installation process, the bolt is screwed down by a common tool, and the head of the torque bolt is screwed off.
The utility model has the advantages that the pile head and the lead are respectively connected with the device body through respective pore channels, when in installation, the transformer pile head connecting hole is screwed into the pile head, and the nut on the pile head is directly screwed in the opposite direction, thereby ensuring the holding effect of the screw rod connecting device on the transformer pile head; after the screw rod wiring device is used, the current flowing path is shorter, the heat emission is less, the loss is small, the material is saved, the processing is simple, the installation is convenient and fast, and the connection is more stable.
