Problems solved by technology

[0005] The existing cable joint detection equipment mainly has the following problems: (1) At present, many cable head defect detections are offline detection. For the used cable joints, it is often necessary to cut off the power first, disconnect the tested line, and take out the tested cable. Access to testing equipment for defect detection of cable joints
During the testing process, it is still unavoidable to dig the cable trench, open the cable trough, connect the test device, etc.
Moreover, the power is not turned off during the detection, which also affects personal safety to a certain extent.

[0042] Such as Figure 1 to Figure 3 As shown, a black box for cable joint detection data recording includes: a box body 100, on which an indicator light 1 and a data interface 9 are arranged; arranged in the box body 100:

[0043] A data access module 50 is connected to the data interface 9;

[0044] A data conversion module 10, connected to the data access module 50, for converting external data into a preset format;

[0045] A storage module 12, connected to the data conversion module 10, for storing data;

[0046] The drive power supply assembly 13 is connected to the data access module 50, the data conversion module 10, and the storage module 12 to provide the required power;

[0047] The main control module 11 is connected with the data access module 50, the data conversion module 10, the storage module 12, and the drive power supply assembly 13, and is used to control the access of the data access module 50, the The data conversion of the data conversion module 10 an...

Embodiment 2

[0065] combine Figure 4 As shown, the present invention provides a cable joint detection data recording system, including a cable, a cable joint connected to the cable, and a cable joint detection data recording black box as described in any one of the above cables connected to the cable joint . The cable joint detection data recording system can record the cable joint characteristic data for a long time through the cable joint detection data recording black box. When an explosion accident occurs at the cable joint, the cable joint detection data recording black box will not be damaged, and the internal The stored data is effectively protected.

Embodiment 3

[0067] The present invention provides a cable joint detection data recording method, including a cable, a cable joint connected to the cable, and a cable joint detection data recording black box as described in any one of the above cables connected to the cable joint. The method includes the following steps:

[0068] The data access module 50 collects the signal of the cable joint; it can be an electrical signal, temperature, sound, light, and heat signal;

[0069] The data conversion module 10 converts the signal into data in a preset format and transmits it to the storage module 12; the data conversion module 10 converts the collected electrical signal, temperature and sound, light, and heat signals into a preset format;

[0070] The storage module 12 stores data in a preset format.

[0071] This method can automatically collect and record various electrical signals, temperature, sound, light, and heat signals of the cable joints collected. The collection process is simple,...

Abstract

The invention discloses a cable joint detection data recording black box, system and method, and the black box comprises a box body which is provided with a data interface and an indicating lamp; anda data access module, a data conversion module, a storage module, a driving power supply assembly and a main control module which are arranged in the box body. The cable joint detection data recordingblack box can be applied to various occasions of cable connector laying, and is small in size and wide in application range; the self-power-taking device is used for self-power-taking or the wirelesscharging module is used for charging, so that the reliability of the driving power supply assembly is ensured; the cable joint detection data recording black box is low in overall power consumption and long in service life; various protection levels are adopted, cold resistance, fire prevention and explosion prevention are achieved, feature data of the cable connector can be recorded for a long time, the cable joint detection data recording black box can be prevented from being affected when explosion accidents happen to the cable connector, and data protection is achieved.

Description

technical field [0001] The invention relates to the technical field of cable detection, in particular to a cable joint detection data recording black box, system and method. Background technique [0002] Cables are one of the equipment with a high probability of failure in the power grid. Due to the influence of factors such as installation process, laying environment, external force damage, and operating conditions, some hidden hidden dangers often appear inside, and internal hidden dangers often develop slowly. The characteristics of sudden and sudden characterization, coupled with the congenital insufficiency of state observability, can not be found in time during the handover and operation stages, and the lack of active disposal means will eventually lead to insulation defects, so that the hidden dangers will expand and accidents will occur due to insulation. Among them, the cable intermediate joint and Terminal heads have the highest percentage of insulation failures. ...
