Problems solved by technology

[0004] When installing a flexible ring-wrapped capacitive sensor on the cable joint, one is usually pasted around each side of the cable joint, and then the metal shielding net is installed. The traditional installation method is manually installed by the operator, and this method has the following problems: 1. The FPC of the flexible capacitive sensor has a circuit, and the dust and sweat on the hands of the operator can easily damage the sensor and affect the detection accuracy of the sensor; 2. The flexible capacitive sensor is manually pressed on the cable connector, and the force is uneven. The sticking is not firm, so that the relative positions of multiple measuring coils on the FPC are inconsistent, which affects the detection accuracy; 3. When installing the metal shielding net, due to the hardness of the metal shielding net, it is inconvenient to surround, and manual installation is easy to cause local depressions and deformations of the metal net. It has a certain impact on the flexible capacitive sensor under the metal mesh, which reduces the detection accuracy
But this invention still adopts artificial installation, can't solve above-mentioned technical problem

Abstract

The invention discloses a flexible ring-pack capacitive sensor installation tool and an installation method, which belong to the technical field of cable joint detection equipment installation. It includes two fixed rings arranged on both sides of the cable joint, and a press-fitting mechanism rotatably connected with the fixed rings; the press-fitting mechanism includes a ring sleeve, a driving part and a press-fitting wheel, and the ring sleeve is sleeved on the fixed ring. On the outside, the driving member is provided on the ring sleeve, and the driving member is provided with the pressing wheel for wrapping the flexible ring-pack capacitive sensor on the cable joint. The invention adopts the installation tool and the installation method to operate in a standardized manner, which ensures that the flexible capacitive sensor is not affected by dirt and uneven force, and also ensures that the shape and shielding effect of the metal shielding net are not affected after installation, thereby ensuring that the capacitive sensor is not affected. In addition, the present invention can complete the installation of the flexible capacitive sensor and the metal shielding net in sequence, with convenient operation and high efficiency.

Description

technical field [0001] The invention relates to the technical field of installation of cable joint detection equipment, in particular to an installation tool and an installation method of a flexible ring-pack capacitive sensor. Background technique [0002] The vast majority of high-voltage cable operation accidents are caused by the high operating temperature of partial discharge and cable joint conductors. The information monitoring of cable temperature and partial discharge is an indispensable and important part of power grid operation monitoring. At present, the detection methods of partial discharge of cable joints are mainly divided into two types: one is the electrical measurement method, which mainly uses two types of sensors, and the other is based on the Rogowski coil measurement principle, which mainly includes electromagnetic coupling method, inductive coupling method and directional coupling method. The second is based on the principle of capacitive coupling, i...
