DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 A cable test platform comprises a mobile platform 1 and a mobile pole 3. The mobile pole 3 is located on the left side of the mobile platform 1. A fixed frame 12 is fixed on the upper end of the mobile platform 1. A platform frame 2 is fixed on the upper end of the fixed frame 12. The platform frame 2 is provided with a lightning arrester 4, a voltage transformer 5, a current transformer 6 and an isolating switch 7 from right to left. The isolating switch 7 improves the safety of the platform. An insulator 8 is provided on the upper end of the mobile pole 3. A ground bull 9 is provided on the left side of the mobile pole 3. The mobile pole 3 is connected to the ground bull 9 through a steel strand 10. A cable pipe 11 is provided on the right side of the mobile platform 1. An outlet 111 is opened at the lower end of the cable pipe 11. The cable 100 passes through the insulator 8, the isolating switch 7, the current transformer 6, the voltage transformer 5 and the lightning arrester 4 in sequence, and then passes through the cable pipe 11 and goes out from the outlet 111. The lower ends of the mobile platform 1 and the mobile pole 3 are both provided with rollers, and the rollers can be locked and fixed.

[0018] In order to increase the stability of the cable test platform, the platform frame 2 is provided with a fourth mounting frame 24, a third mounting frame 23, a second mounting frame 22 and a first mounting frame 21 from left to right. The fourth mounting frame 24 is provided with an isolating switch 7, the third mounting frame 23 is provided with a current transformer 6, the second mounting frame 22 is provided with a voltage transformer 5, and the first mounting frame 21 is provided with a lightning arrester 4.

[0020] In this embodiment, the insulator 8 is made of glass insulator. The damage of the glass insulator is visible to the naked eye, so the regular preventive test with power on during operation can be cancelled.

[0021] When in use, the mobile platform 1 and the mobile pole 3 are moved to the test site, the rollers are locked to fix the mobile platform 1 and the mobile pole 3, and the grounding bull 9 and the grounding bar 13 are fixed on the ground nearby. The grounding bull 9 is located on the left side of the mobile pole 3, and the fixing frame 12 is connected to the grounding bar 13 through the steel rope 10. At the same time, the mobile pole 3 is connected to the grounding bull 9 through the steel rope 10, so that the mobile pole 3 and the fixing frame 12 are more stable to prevent the mobile platform 1 and the mobile pole 3 from tilting during the test. After the cable 100 is installed, it is energized, and the voltage transformer 5 and the current transformer 6 convert the high voltage and large current into low voltage and small current for the test instrument to test.
