Description

Technical Field

[0001] The utility model belongs to the technical field of transformers, and in particular relates to an insulating cylinder used for an ultra-high voltage transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization (magnetic saturation transformer). Transformer insulation cylinders are mainly used in indoor high-voltage vacuum circuit breakers. They play a supporting, insulating and dustproof role for vacuum interrupters, upper and lower outlet seats (conductors), insulating pull rods, etc.

[0003] The current insulating cylinder is a simple cylindrical shape. When the wires are led out, a large part of the wires are exposed to humid air, or the wires are exposed to the sun for a long time. The wires are easily affected by the outside world, which can cause short circuits or leakage accidents, shorten the service life of the wires, and increase maintenance costs.

[0004] Therefore, in view of the above problems, a transformer insulation cylinder is provided which can wrap the electric wires to prevent the electric wires from being in a wet or dry environment for a long time. Utility Model Content

[0005] The utility model aims to solve the above-mentioned technical problems and to provide a transformer insulation cylinder which can wrap electric wires and prevent the electric wires from being in a wet or dry environment for a long time.

[0006] In view of this, the utility model provides an insulating cylinder for a UHV transformer, comprising:

[0007] Insulating tube body;

[0008] The vacuum interrupter is arranged at the upper end of the outer surface of the insulating tube body;

[0009] The line inlet port is arranged adjacent to the insulating cylinder body and the vacuum interrupter chamber;

[0010] The outlet port is provided at the bottom of the outer surface of the insulating tube body;

[0011] The invention is characterized in that: it also includes an anti-short circuit component, which is arranged on the outlet port and is used to prevent the lead-out wires from being exposed outside;

[0012] Among them, the anti-short circuit components include:

[0013] A wire connection block is arranged at the bottom of the insulation cylinder body and connected to the outlet port;

[0014] A guide cavity is provided in the wire connection block, and the guide cavity is communicated with the outlet port;

[0015] The insulating bent pipes are provided in plurality and are arranged on one side of the wire connection block. The insulating bent pipes are communicated with the guide cavity.

[0016] In the present technical scheme, the vacuum arc extinguishing chamber has excellent insulation properties, so that the medium and high voltage circuit can quickly extinguish the arc and suppress the current after the power is cut off, thereby avoiding accidents and unexpected events. The wires are connected from the incoming port to the inside of the insulating cylinder body, and then the wires are connected from the outgoing port. When the wires are connected from the outgoing port, a large part of the wires are exposed to the outside. The exposed wires are in a humid or dry natural weather environment for a long time, which can easily cause the wires to short-circuit or leak. In order to prevent the wires from short-circuiting or leaking, an insulating elbow is provided at the outgoing port, and the wires are connected from the insulating elbow. The insulating elbow can not only play an insulating role, but also prevent the wires from being exposed to the outside, so as to ensure that the wires will not be short-circuited or leaked due to being exposed to the outside for a long time.

[0017] Specifically, the wire is connected from the incoming port to the insulating cylinder body, and then the wire is connected from the outgoing port along the insulating cylinder body. At this time, the wire is located in the guide cavity of the wire connecting block, and the wire is further connected from the guide cavity to the insulating bent pipe, and then moved out from the insulating bent pipe. The insulating bent pipe can prevent the wire from being exposed to the outside, so as to ensure that the wire will not be affected by short circuit or leakage due to long-term exposure to the outside, thereby eliminating fire accidents from the root and improving the safety and stability of the insulating cylinder body.

[0018] In the above technical solution, further, a bracket is provided on the wire connecting block, and the insulating bent pipe is supported by the bracket.

[0019] In the present technical solution, the insulating bent pipe is supported by a bracket, so that the insulating bent pipe is more stable and the access to the wire is more stable.

[0020] The bracket is installed on the wire connection block by bolts or screws, which is easy to install and disassemble.

[0021] In any of the above technical solutions, further, a connecting cylinder is provided on one side of the insulating cylinder body.

[0022] In the present technical solution, a connecting tube is provided on the insulating tube body, and the connecting tube serves as an extension end of the insulating tube body. The insulating tube body is installed through the connecting tube, thereby eliminating the need to directly install the insulating tube body, thereby avoiding damage to the insulating tube body during installation.

[0023] In any of the above technical solutions, further, the length of the connecting tube is 1 / 4 or 3 / 6 of the length of the insulating tube body.

[0024] In the technical solution, by setting the length of the connecting tube to 1 / 4 or 3 / 6 of the length of the insulating tube body, resources for manufacturing the connecting tube are saved, making the device more uniform as a whole.

[0025] In any of the above technical solutions, further, a mounting assembly is provided on the connecting tube for mounting the insulating tube body.

[0026] In the technical solution, by arranging the installation assembly on the connecting cylinder, it is convenient to install the insulating cylinder body, and the installation is convenient and convenient to replace or overhaul.

[0027] In any of the above technical solutions, further, the installation component includes:

[0028] A mounting plate is arranged on the outer surface of the connecting tube;

[0029] A plurality of support blocks are provided respectively around the mounting plate;

[0030] A bidirectional ball screw is arranged between two adjacent support blocks on the same side, and the bidirectional ball screw is threadedly connected to the support blocks;

[0031] The clamping pieces are arranged on both sides of the bidirectional ball screw, the two clamping pieces are both threadedly connected to the bidirectional ball screw, and the opposite surfaces of the two clamping pieces contact each other and cover the outer surface of the connecting tube;

[0032] The motor is arranged on the mounting plate, and the output shaft of the motor is connected to one end of the bidirectional ball screw;

[0033] The guide rod is arranged on the two support blocks on the other side, and the two clamping members are slidably connected to the guide rod.

[0034] In the present technical solution, since the current insulating tube body is installed by bolts, the bolt installation process is relatively cumbersome and needs to be tightened manually one by one. This not only consumes a long time and manpower, but also the bolts are prone to aging or rusting. The rusted bolts are prone to breakage, which makes the installation of the insulating tube body unstable and causes certain damage.

[0035] Among them, the bidirectional ball screw is driven by a motor to rotate clockwise or counterclockwise, so that the clamping part moves to the left or right side, so that the clamping part clamps and fixes the connecting tube, and the connecting tube is fixedly connected to the insulating tube body, thereby installing the insulating tube body in a specified position, saving time, saving manpower, improving the installation efficiency of the insulating tube body, and avoiding damage to the insulating tube body caused by unstable installation.

[0036] Specifically, when the insulating cylinder body needs to be inspected and repaired, the motor is used as a driving force to drive the bidirectional ball screw to rotate clockwise, and the clamping members on both sides move along the guide rod to the side away from each other, so that the clamping members on both sides do not contact each other and do not clamp the connecting cylinder. At this time, people can inspect the insulating cylinder body. After the inspection and repair of the insulating cylinder body is completed, the motor is controlled to drive the bidirectional ball screw to rotate counterclockwise, so that the clamping members on both sides move along the guide rod to the side close to each other. The clamping members move until they contact the outer wall of the connecting cylinder and clamp the connecting cylinder, and then the insulating cylinder body is installed in the specified position. Finally, the insulating cylinder body can be installed automatically, which saves manpower, improves work efficiency, and at the same time improves the stability of the installation of the insulating cylinder body.

[0037] In any of the above technical solutions, further, a semicircular groove is provided on the clamping member, and the semicircular grooves on the two clamping members are combined to form a circular groove, and the clamping member covers the outer wall of the connecting tube through the circular groove.

[0038] In this technical solution, a semicircular groove is opened on the clamping frame so that the two clamping parts contact each other, so that the semicircular grooves on the clamping parts combine to form a circular groove. The clamping parts move until the semicircular groove contacts the outer wall of the connecting tube, so that the semicircular groove clamps the connecting tube, which makes the clamping more stable.

[0039] In any of the above technical solutions, further, the inner surface volume of the circular groove is the same as the outer surface volume of the connecting tube.

[0040] In the present technical solution, the volume of the circular groove is the same as the volume of the outer surface of the connecting tube, so that the circular groove can fit the outer surface of the connecting tube more closely, thereby clamping the connecting tube more accurately and improving the stability of the clamping of the connecting tube.

[0041] In any of the above technical solutions, further, it also includes exhaust shoulders, which are arranged on both sides of the outer side wall of the insulation tube body.

[0042] In the present technical solution, exhaust shoulders are arranged on both sides of the outer wall of the insulating tube body, and the exhaust shoulders are connected to the internal cavity of the insulating tube body, thereby forming a convection heat dissipation effect, facilitating the dissipation of heat in the insulating tube body, ensuring the heat dissipation effect, and being practical and convenient; at the same time, the exhaust shoulders can prevent foreign matter or dust from entering, effectively improving the heat dissipation capacity.

[0043] The beneficial effects of the utility model are:

[0044] 1. The insulating bend can prevent the wires from being exposed to the outside, so as to ensure that the wires will not be affected by short circuit or leakage due to long-term exposure, eliminate fire accidents from the root, and improve the safety and stability of the insulating tube body;

[0045] 2. The motor is used as the driving force to drive the bidirectional ball screw to rotate, so that the clamping piece fixes and clamps the connecting tube. This not only saves manpower and improves work efficiency, but also can replace the existing insulating tube body which is installed in the specified position by bolts, which takes a long time. Secondly, the bolts are easy to rust, which affects the installation stability of the insulating tube body.

[0046] 3. By making the inner surface volume of the circular groove on the clamping piece the same as the outer surface volume of the connecting tube, the circular groove is more closely fitted to the outer surface of the connecting tube, so that the clamping piece can clamp the connecting tube more firmly;

[0047] 4. By arranging exhaust shoulders on both sides of the outer wall of the insulation tube body, the exhaust shoulders on both sides form a convection heat dissipation effect, which is convenient for heat dissipation in the insulation tube body, ensures the heat dissipation effect, and is practical and convenient.

In order to prevent the wires from short-circuiting or leaking, an insulating bend 53 is provided at the outgoing port 4, and the wires are connected from the insulating bend 53.

At this time, people can inspect and repair the insulating cylinder body 1. After the inspection and repair of the insulating cylinder body 1 is completed, the motor 85 is controlled to drive the bidirectional ball screw 83 to rotate counterclockwise, so that the clamping members 84 on both sides move along the guide rod 86 to the side close to each other. The clamping members 84 move until they contact the outer wall of the connecting cylinder 7 and clamp the connecting cylinder 7, and then the insulating cylinder body 1 is installed in the specified position. Finally, the insulating cylinder body 1 can be installed automatically, which saves manpower, improves work efficiency, and at the same time improves the stability of the installation of the insulating cylinder body 1.
