Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] Such as figure 1 and figure 2 As shown, this embodiment provides a protective device for protecting a gas-insulated closed switchgear terminal 30 of a cable. The protective device includes a protective shell 10 and a buffer structure 20, and the protective shell 10 is sleeved on the outer periphery of the terminal 30; the buffer The structure 20 is set in the protective shell 10 to isolate the terminal 30 from the inner wall of the protective shell 10 ; wherein, when the cable is repaired, the protective device is sleeved on the outer periphery of the terminal 30 to protect the terminal 30 .

[0023] In this embodiment, since the protection device is provided for the GIS terminal 30, ...

Abstract

The invention provides a protection device and a cable with the protection device. The protection device is used for protecting a gas insulation enclosed switchgear terminal of a cable. The protectiondevice comprises a protective casing sleeved on the outer periphery of the terminal; and a buffer structure disposed in the protective casing to isolate the terminal from the inner wall surface of the protective casing; wherein when the cable is repaired, the protection device is sleeved on the outer periphery of the terminal to protect the terminal. By applying the technical solution of the present invention, the problem of high damage rate of the GIS terminal in the repair process of the cable line in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of tunnel cables, in particular to a protection device and a cable having the same. Background technique [0002] During the emergency repair process of the cable line, after the cable GIS (gas insulated switchgear) terminal joint is finished, due to the delay in the test or the cooperation of the substation professional, the construction time limit, etc., the finished GIS terminal can only be placed in the Inside the substation. During this period, professional construction personnel such as civil engineering and power substation are still working, and it is very likely that they will collide with the GIS terminal, which will greatly increase the damage rate of the GIS terminal joint, which will not only increase the cost, but also cause the power generation time to increase. delay. Contents of the invention [0003] The main purpose of the present invention is to provide a protection device and a cable...
