Description
Technical Field
The utility model relates to a cable equipment field particularly, relates to a cable termination explosion early warning device.
Background
Air gaps, impurities, scratches and the like can be left on the insulating surface at the joint of the cable and the transformer due to the problems of technical process and the like, so that the insulation is damaged; or moist water vapor enters the cable terminal insulating layer due to poor sealing treatment; or the cable insulation can be aged to different degrees due to factors such as electric heat, chemistry, environment and the like in operation; causing the insulation performance to be degraded and even the insulation layer to be broken down to form discharge. At this time, a large amount of heat is generated, resulting in the bursting or burning of the fault; on the other hand, at the cable terminal near the transformer, the heat generated by the short circuit can be extremely exploded due to the high voltage, and a so-called cable blasting accident is formed along with the large explosion sound.
Although few people are near the cable terminal at ordinary times, the substation often needs some temporary work such as inspection and maintenance. When a worker works near the end of a cable, an accident or panic may be caused once a "cable blasting" accident is created.
When monitoring for such problems, a partial discharge signal, or a temperature signal, is typically monitored. Partial discharge detection of a cable terminal is a better method, for example, when the cable terminal is manufactured, a partial discharge sensor (inductive or capacitive) is integrated on a cable accessory shell in advance, and once current is abnormal, an alarm can be actively given. However, such devices typically require installation at the time of cable termination construction, require added re-construction at a later time and may be at risk.
For common requirements, such as temporary working near a cable terminal by a worker, a non-contact infrared temperature measurement mode can be generally used for detection. In fact, at present, most of the time, the handheld infrared detection is adopted, the data are obtained in a non-contact and real-time visible mode without modifying the cable terminal, and whether the temperature of the cable terminal fluctuates or not and whether the temperature is caused by internal faults of the cable terminal is analyzed according to the data. The method is simple and economical to operate, but has the following problems:
(1) Workers who go to temporary dry life are difficult to hold the infrared detector for continuous testing during work. Thus, if discharge explosion occurs during working, early warning cannot be actually realized;
(2) In a transformer substation, the number of cable terminals is often large, and it is impossible to set a large number of workers to monitor each cable terminal by using handheld infrared.
Therefore, the prior art has the problem that the detection of the cable terminal is difficult.
