Description

Technical Field

[0001] This utility model relates to the technical field of cable testing devices, and more specifically, to a split-type tank high-pressure testing device. Background Technology

[0002] Cables are important transmission equipment in power systems, enabling the smooth transmission of electricity and signals.

[0003] Traditional cable testing devices only support insertion testing at both ends and cannot detect repairs to damage in the middle section. Furthermore, with the increasing number of submarine cables and other ultra-long conductors, even if repaired, it is impossible to independently verify whether the electrical performance of the repaired cables meets the requirements for use.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0005] The purpose of this invention is to provide a split-type tank high-pressure testing device, which can support electrical performance testing of cables after disassembly and repair at any location, thereby expanding the testing scenarios of the device.

[0006] This utility model provides a split-type tank high-pressure detection device, including an upper tank, a lower tank, a sealing assembly, a filling / draining valve, a pressure gauge, and a high-pressure input disc. Both the upper and lower tanks are hollow semi-cylindrical shapes. A connecting pipe is provided on the side of the upper tank, and the high-pressure input disc is detachably connected to the connecting pipe. The filling / draining valve is also connected to the side of the upper tank, and the pressure gauge is connected to the filling / draining valve. Semi-circular notches are provided at both ends of the upper and lower tanks, and the upper tank is detachably connected to the lower tank. A wire hole is formed between the semi-circular notches on the upper and lower tanks, and the sealing assembly is disposed in the wire hole.

[0007] Using the above technical solution, the high-voltage cable to be tested is placed in the tank formed between the upper and lower tanks. Both ends of the high-voltage cable pass through the wire holes, and the sealing component is used to seal the high-voltage cable with the inside of the tank. The upper and lower tanks are designed to be separate and detachable, which allows for electrical performance testing of the cable after it has been repaired and can be disassembled at any location, thus expanding the testing scenarios of the device.

[0008] Furthermore, a sealing groove is provided at the upper opening of the lower tank body, and a sealing strip is provided in the sealing groove.

[0009] Furthermore, the sealing assembly includes a sealing rubber, a first sealing plate, and a second sealing plate; the sealing rubber, the first sealing plate, and the second sealing plate are all annular, with a groove on the inner wall of the semi-circular notch, the sealing rubber being disposed in the groove, the second sealing plate pressing on the sealing rubber, and the first sealing plate pressing on the second sealing plate, with four connecting holes on the first sealing plate; when the upper tank is connected to the lower tank, half of the first sealing plate presses on the end face of the upper tank, and the other half of the first sealing plate presses on the end face of the lower tank, and is locked to the upper and lower tanks by bolts passing through the connecting holes.

[0010] Using the above technical solution, when in use, both ends of the high-voltage cable pass through the inner holes of the sealing rubber, the first sealing plate, and the second sealing plate. The sealing rubber is used to form a seal between the high-voltage cable and the inside of the tank.

[0011] Furthermore, both the upper tank and the lower tank have extended edges at their left and right openings, and the extended edges have through holes; when the upper tank is connected to the lower tank, it is locked by bolts passing through the through holes.

[0012] Furthermore, a connecting pipe is provided on the side of the lower tank, and the sealing cap is detachably connected to the connecting pipe.

[0013] The split-type tank high-pressure testing device provided by this utility model involves placing the high-voltage cable to be tested inside the tank formed between the upper and lower tanks. Both ends of the high-voltage cable pass through the wire holes, and the sealing component is used to seal the high-voltage cable to the inside of the tank. The device adopts a split and detachable structure of upper and lower tanks, which can support electrical performance testing of the cable after it has been repaired and disassembled at any position, thus expanding the testing scenarios of the device.
