Description

Technical Field

[0001] The utility model belongs to the technical field of lightning arrester detection and subassembly, and specifically relates to a lightning arrester detection and subassembly system of 35kV and above. Background Art

[0002] Lightning arresters are used to protect power lines and electrical equipment in power systems from high transient overvoltages, operating overvoltages, and power frequency transient overvoltages during lightning strikes, and to limit the follow-on time and often the follow-on value. Lightning arresters are sometimes also called overvoltage protectors or overvoltage limiters. Lightning arresters are connected between cables and the earth, usually in parallel with the protected equipment, and can effectively protect electrical equipment. When electrical equipment is operating at normal operating voltage, the lightning arrester will not take effect and will be considered as an open circuit to the ground; when high voltage appears and endangers the insulation of the protected equipment, the lightning arrester will immediately operate to direct the high voltage impact current to the earth, thereby limiting the voltage amplitude and protecting power lines and equipment; when the overvoltage disappears, the lightning arrester quickly returns to its original state, allowing the electrical equipment to operate normally.

[0003] During the production process, lightning arresters need to be tested with high voltage to check whether their quality is qualified and to separate qualified and unqualified products. However, the existing distribution network lightning arrester detection and packaging production line has a low degree of integration and intelligence, which makes the detection and packaging efficiency very low, greatly affecting the processing fluency.

The first forward and reverse screw slide and the second forward and reverse screw slide are powered by a servo motor, which can accurately control the movement distance of the first clamping jaw fixing seat, the second clamping jaw fixing seat, the third clamping jaw fixing seat, and the fourth clamping jaw, thereby accurately controlling the opening and closing dimensions between the first clamping jaw and the second clamping jaw, and between the third clamping jaw and the fourth clamping jaw to adapt to the clamping of lightning arresters of different sizes. The lifting slide can move the second forward and reverse screw slide up and down to match the clamping position of lightning arresters of different heights, effectively solving the problem that the existing lightning arrester handling fixture has a small application range and can only clamp products of a single size.

[0027] 2. In the utility model, the cable drag chain of the handling fixture stores the electrical components and lines to avoid affecting the clamping and handling work of the lightning arrester.

[0028] 3. In the utility model, the first jaw, the second jaw, the third jaw and the fourth jaw of the handling clamp are made of aluminum alloy, ensuring that no axial or radial movement occurs within the closed size of the first reverse screw slide and the second forward and reverse screw slide, and the high-strength aluminum alloy jaw itself can overcome the bending moment caused by the large-mass lightning arrester.

[0029] 4. In the utility model, the transport fixture is provided with a universal connecting plate to facilitate installation of the fixture as a whole on different driving components, thereby increasing the versatility of the fixture.

[0030] 5. In the utility model, after the arrester to be tested is placed on the fixed seat of the test fixture, the reduction motor drives the rotating platform to rotate so that the barcode scanner on the rotating platform scans the QR code at the bottom of the arrester, which is convenient for recording the arrester test information. The dual-axis cylinder controls the fixed clamp to fix the arrester to prevent the arrester from tipping over during the test. The servo drive motor of the power assembly drives the lower pulley to rotate, and the lower pulley cooperates with the upper pulley to drive the movable plate on the belt to rise and fall. The movable plate is connected to the first connecting plate through the cross plate, so that the first connecting plate is synchronously lifted and lowered along the height direction of the insulating pillar, and then drives the equalizing ring to rise and fall, so as to test the arrester of different height sizes. The insulating pillar can isolate the 400kV DC high-voltage power supply while serving as the equalizing ring lifting guide mechanism, reducing or isolating the leakage current. The telescopic lead tube is used to connect with the DC power supply, introduce the high voltage of the DC power supply into the equalizing ring, and the telescopic lead tube can be adjusted to adjust the length when the equalizing ring rises and falls to ensure the normal operation of the equipment, and the telescopic lead tube made of aluminum foil can effectively reduce corona. The voltage-equalizing ring introduces high-voltage DC electricity into the upper flange end of the arrester to test the arrester. Since the voltage-equalizing ring is made of rust-proof aluminum plate, it can effectively improve the high-voltage electric field environment. A pin is provided on the upper part of the voltage-equalizing ring, and a spiral compression spring is sleeved on the pin, so that the contact between the voltage-equalizing ring and the arrester is soft contact during the test. While ensuring effective electrical contact between the voltage-equalizing ring and the upper flange end of the arrester during the test, it will not cause damage to the arrester. The double-helix telescopic air pipe provides an air source for the machine-controlled valve, and can be extended and retracted when the voltage-equalizing ring is raised or lowered so as to supply an air source to the machine-controlled valve without being affected by height changes. Through the above design, the test fixture can be applied to arresters of different sizes, which effectively solves the problem that the existing arrester test fixture can only complete the test of arresters of a single size and has a small scope of application.

While ensuring effective electrical contact between the voltage-equalizing ring and the upper flange end of the arrester during the test, it will not cause damage to the arrester. The double-helix telescopic air pipe provides an air source for the machine-controlled valve, and can be extended and retracted when the voltage-equalizing ring is raised or lowered so as to supply an air source to the machine-controlled valve without being affected by height changes. Through the above design, the test fixture can be applied to arresters of different sizes, which effectively solves the problem that the existing arrester test fixture can only complete the test of arresters of a single size and has a small scope of application.
