Fault point intellectualized diagnosis and repairing method for geothermal cable and device

Abstract

The invention provides a fault point intellectualized diagnosis and repairing method for a geothermal cable and a device. The device comprises a control module, a detection module, a tracing signal module, a test module, a high pressure welding module and a man-machine interaction interface, wherein the detection module is used for detecting a magnetic filed signal near the geothermal cable, the tracing signal module is used for generating high frequency an alternating signal, and high frequency alternating signal input is exerted between the geothermal cable and a shielding line of the cable which form a loop, the test module is used for detecting whether a break point exists on the geothermal cable and whether the loop exists between the geothermal cable and the shielding line of the cable, the high pressure welding module is used for generating high pressure pulse and adding high pressure pulse at two ends of the geothermal cable having a break point to weld the break point, and the man-machine interaction interface is used for achieve interaction between an operator and the device. The device can automatically locate a fault point and can achieve automatic repair of the break point for the cable with a small break position. For the break pint which can not be automatically repaired, the device can enable the repair work to have smallest damage to the ground by accurately finding a the position of the break point.

Description

Technical field [0001] The invention relates to an intelligent fault point diagnosis and repair technology of a thermal storage type geothermal cable, in particular to a method and device for the intelligent fault point diagnosis and repair of a geothermal cable. Background technique [0002] With the improvement of the people's living standards and the strengthening of the awareness of environmental pollution hazards, the use of electricity for heating has increasingly shown its advantages. Especially in recent years, the thermal storage type geothermal cable floor radiant heating has been welcomed by users because of its high comfort, low cost, environmental protection and pollution-free characteristics. [0003] However, since the cables need to be laid below the ground concrete layer, once the cables fail, it is quite difficult to repair them. At present, the domestic fault detection and repair technology for thermal storage geothermal cables is still blank. Most of them still...
