Embodiment Construction

[0039] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0040] A cable leakage detection system for a pipe gallery, including a temperature measuring host, a temperature measuring optical fiber, an information output host, and several distance identification labels. The temperature host collects the surface temperature information of the pipe gallery cable, and the information output host communicates with the temperature measurement host through the network to realize the setting of temperature limit parameters and the division of detection areas. When the collected temperature exceeds the set temperature limit , an alarm message is output.

[0041] Such as figure 2 As shown, in this embodiment, the pipe gallery cable is composed of a cable core layer 1, a cable insulation layer 2 and a cable protective layer 3, and the temperature measuring optical fiber 4 is spirally wound on the outer surface of the...

Abstract

The invention discloses a pipe gallery cable electric leakage detection system and detection method, the detection system comprises a temperature measurement host, a temperature measurement optical fiber and an information output host, the temperature measurement optical fiber is wound on a to-be-detected pipe gallery cable and is connected with the temperature measurement host, and the surface temperature information of the pipe gallery cable is acquired through the temperature measurement host. The information output host is connected with the temperature measurement host through a network for communication, setting of temperature limit value parameters and division of detection areas are achieved, and when the collected temperature exceeds the set temperature limit value, alarm information is output. Maintenance personnel go to the site for processing, determine an electric leakage point location according to the temperature measurement information after locking a certain region section according to the distance identification label, and process the electric leakage point location. The method is high in measurement precision and wide in coverage, the false alarm rate and the missing report rate are greatly reduced, and real-time detection can be achieved. The cost is far lower than that of the existing detection technology.

Description

technical field [0001] The invention belongs to the field of electricity transmission, and relates to a cable leakage detection technology, in particular to a cable leakage detection system and a detection method for a pipe gallery. Background technique [0002] With the advancement of my country's urbanization process, the rapid expansion of the scale of urban underground cables and the continuous improvement of voltage levels, the safety and reliability of power operations have become increasingly prominent. Cable leakage will cause the power supply terminal in the power system to raise the voltage and affect the electrical system. The normal use of the equipment will increase the loss of power consumption. Severe cases may cause major accidents such as fires. [0003] Cable leakage may occur at any point in the entire life cycle. In order to detect these defects at an early stage, it is very necessary to have detailed information about cable leakage. The non-contact capa...
