Description

Technical Field

[0001] The utility model relates to the technical field of power system equipment, in particular to an arc suppression coil with an anti-winding function. Background Art

[0002] Arc suppression coil is a device used in power systems. Its main function is to provide inductive current to compensate for the grid's ground capacitance current when a single-phase ground fault occurs in the power grid, reduce the fault current, and lower the arc recovery voltage, thereby helping to extinguish the arc, reduce the generation of overvoltage, and protect power equipment and transmission lines.

[0003] The existing arc suppression coil is an integrated winding coil, and the coil wire is often long. During installation, debugging, maintenance, or replacement, the long wire is prone to entanglement, which greatly wastes the operator's time.

[0004] Therefore, to address the above problems, an arc suppression coil with anti-entanglement function can be designed. The coil wire can be segmented and assembled modularly, so that the device can intuitively and freely select the number of wires and reduce the waste of replacement materials. Utility Model Content

[0005] In order to overcome the problem that most existing arc suppression coils are wound in one piece, the coil wire is often of a long length. During installation, debugging, maintenance or replacement, the long wire is prone to entanglement, which greatly increases the time wasted by the operator.

[0006] The technical solution of the utility model is: an arc extinguishing coil with an anti-winding function, comprising a base, a metal column piece, a connecting cross frame piece, a stacked winding seat, an induction coil, a protection plate and a connecting rod; a metal column piece is arranged above the base, a connecting cross frame piece is arranged above the metal column piece, a stacked winding seat is arranged on the outside of the metal column piece, an induction coil is arranged on the inside of the stacked winding seat, a protective plate is arranged on the outside of the stacked winding seat, and a connecting rod is arranged on one side of the protection plate.

[0007] Preferably, a base is provided to bear the weight of the device, a metal column plate, a connecting cross frame plate and an induction coil are used to form an arc extinguishing coil and realize the function of the arc extinguishing coil, a stacked winding seat is used to accommodate the induction coil to realize modularization, reduce the length of a single wire, reduce the occurrence of wire entanglement, use a protective plate to protect the induction coil, and connect multiple groups of induction coils through a connecting rod to connect the induction coils to each other.

[0008] Preferably, multiple groups of metal column sheets and connecting cross frame sheets are provided, and the metal column sheets and connecting cross frame sheets are stacked alternately; the staggered stacking method facilitates the production of parts and the replacement of damaged parts.

[0009] Preferably, a fixing hole is provided on one side of the metal column piece, and fixing holes are provided on both sides of the connecting cross frame piece, and threaded connectors are provided in the fixing holes; the metal column piece and the connecting cross frame piece are connected and fixed by accommodating the threaded connectors through the fixing holes.

[0010] Preferably, limit plates are provided on the upper and lower sides of the stacked winding seat, and multiple groups of threaded holes are provided on the outer side of the limit plates; the wire of the induction coil is limited by the limit plates, and the threaded holes are used to facilitate the connection of the protection plate.

[0011] Preferably, a fixing hole is opened on the inner side of the stacked winding seat, the fixing hole is rectangular, and the side length of the fixing hole is consistent with the width of the metal column sheet; the stacked winding seat is limited by the cooperation of the metal column composed of the fixing hole and the metal column sheet.

[0012] Preferably, multiple groups of protection plates are provided, and fixing screws are provided on the inner side of the protection plates, which are threadedly connected to the threaded holes; the protection plates are connected and fixed to the stacked winding seat through the threaded connection between the fixing screws and the threaded holes.

[0013] Preferably, two groups of wiring terminals are provided on one side of a group of protection plates, and the wiring terminals are divided into positive and negative poles. One end of the connecting rod is connected to the positive wiring terminals of one group of protection plates, and the other end of the connecting rod is connected to the negative wiring terminals of another group of protection plates; other electrical equipment and the connecting rod are connected through the wiring terminals.

[0014] Beneficial effects of the utility model:

[0015] 1. Compared with the traditional existing arc suppression coil, the winding coil is an integrated type, and the coil wire is often longer. During installation, commissioning, maintenance and replacement, the long wire is easy to get tangled, which greatly increases the time wasted by the operator. This device makes the original integrated coil into a modular setting by separating the coils, which reduces the difficulty of coil arrangement and the probability of coil tangling. At the same time, the coils can be repaired and replaced separately, reducing material consumption.

[0016] 2. When assembling the device, align the fixing screws with the threaded holes and screw them in to connect and fix the protection plate to the stacked winding seat. After arranging the metal column pieces into two metal columns, align the fixing holes with the metal columns, insert the stacked winding seat into the metal columns and stack them, and make the protection plate with the terminal block face the same side. Then insert the connecting cross frame piece and the metal column piece alternately and align the fixing holes. Use threaded connectors to connect and fix the metal column piece and the connecting cross frame piece. Connect the two ends of the connecting rod to the positive and negative terminals of the two sets of induction coils respectively so that the two sets of induction coils can be electrically connected. Finally, connect the remaining two sets of terminals to the positive and negative poles of other equipment to complete the assembly of the device. Modular assembly reduces the difficulty of arranging wires to solve the problem that the winding coils of most existing arc suppression coils are integrated and the coil wires are often long. During installation, debugging, maintenance or replacement, the long wires are prone to entanglement, which greatly increases the problem of wasted time for operators.

[0017] 3. When inspecting and replacing the device, use an external power supply to connect the two sets of terminal blocks of the same stacked winding seat, test the stacked winding seat separately, and after determining the location of the damaged induction coil, replace the corresponding stacked winding seat separately, avoiding the waste of materials caused by overall replacement.
