Description

Technical Field

[0001] The invention relates to a cable test platform, in particular to a cable test integrated self-unloading device platform. Background Art

[0002] Power cables are used to transmit high-power electrical energy and generally work under high voltage and high current conditions, so their electrical performance requirements are very high. Cable testing is a key item in power handover tests and preventive tests. It mainly checks the cable quality, insulation condition and performs various tests on the cable lines, which can effectively reduce operating accidents and improve power supply reliability. Traditional cable testing requires that test equipment such as variable frequency power supply, excitation transformer, resonant reactor, capacitive voltage divider, and compensation capacitor be installed on a special transport vehicle and transported to the site. After being removed from the transport vehicle, the test equipment is wired and debugged, which is inefficient and has safety hazards of incorrect wiring. Summary of the invention

[0003] The invention provides a cable test integrated self-unloading device platform to overcome the defects of heavy workload, low efficiency and poor safety of on-site cable test workers in the prior art.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] The present invention discloses an integrated self-unloading device platform for cable testing, comprising a device platform, wherein the outer wall of the device platform is movably connected with a side wall, and the device platform comprises a box body connected to the inner side of a support leg, and the inner cavity of the box body is divided into a control room and an equipment room by a metal partition, and an operating table and a seat are arranged in the control room, and a variable frequency power supply, an excitation transformer, a resonant inductor, a compensating inductor, an AC voltage divider and a generator for cable testing are respectively integrated in the equipment room, and the generator is a total power element.

[0006] Furthermore, the side wall is opened and closed by electric hydraulic control, and can be opened on one side or on both sides simultaneously.

[0007] Furthermore, the box body is fixed to the electric legs by bolt connection, and the electric legs can be extended and retracted vertically and horizontally.

[0008] Furthermore, the variable frequency power supply, excitation transformer, resonant inductor, compensating inductor, AC voltage divider and generator are all electrically connected to the device platform.

[0009] Furthermore, an industrial computer and a test operating system are placed on the operating table to control the instruments in the equipment room.

[0010] The beneficial effect achieved by the present invention is that by integrating the instrument equipment, operating system and power supply system, the problem of low efficiency and poor safety of traditional cable testing is solved. The cable test operation time is relatively long. Compared with the special test vehicle, the device platform can be self-disassembled and can be operated by a conventional trailer during transportation, without occupying vehicle resources separately, which can reduce user investment.

[0015] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0016] Example 1

[0017] like Figure 1-2 As shown, a cable test integrated self-unloading device platform includes a device platform, the outer wall of the device platform is movably connected to the side wall 1, and the inner side of the device platform includes and is connected to the support leg 3. The inner cavity of the box body 2 is divided into a control room 4 and an equipment room 5 by a metal partition 6. The control room 4 is provided with an operating table 7 and a seat 8. The equipment room 5 is respectively integrated with a variable frequency power supply 9 for cable testing, an excitation transformer 10, a resonant inductor 11, a compensating inductor 12, an AC voltage divider 13 and a generator 14, and the generator is a total power element.

[0018] Working process: The expandable and closable side wall 1 is controlled by electric hydraulics and powered by a generator 14. During on-site operations, the side wall 1 can be directly expanded. After expansion, cable wiring can be carried out for experiments. According to needs, the side wall 1 can be expanded on one side or on both sides at the same time.

[0019] The device platform as a whole is composed of a box body 2 and an electric outrigger 3, which are fixed by bolts. The electric outrigger 3 can be extended vertically and horizontally. The outriggers are extended during operation and storage to facilitate transportation with a flatbed trailer. The electric outriggers are retracted during transportation to keep the width dimension to a minimum. The power for the electric outriggers is provided by a generator 14.

[0020] The box 2 is composed of a control room 4 and an equipment room 5, which are separated by a metal partition 6 to prevent electric shock accidents caused by accidentally entering the high-voltage equipment room 5 during test operations. An operating table 7 and a seat 8 are provided in the control room 4. An industrial computer and a test operating system are placed on the operating table 7 to control and operate the instruments in the equipment room 5. The equipment room 5 integrates test equipment such as a variable frequency power supply 9, an excitation transformer 10, a resonant reactor 11, a compensating reactor 12, and an AC voltage divider 13 for cable testing. The wiring of each device is connected on the platform, and no further connection is required on site. The power supply of the test equipment and the control room operating table is provided by a generator 14, and can also be connected to the mains through the prefabricated mains access port on the platform.

[0021] When the platform is transported to the site and is ready to be put into operation, the generator 14 is started first, and then the electric outriggers 3 are operated to extend horizontally and downward. After the platform is supported and stabilized, the side wall 1 of the box is opened as needed to connect the cables and the test equipment. After the connection, enter the control room 4 to start the equipment and start the test. After the test, turn off the power supply of the equipment, close the side wall 1, and after the trailer is in place, operate the electric outriggers 4 to retract vertically and then horizontally, and turn off the generator to complete the operation.
