Description
Technical field
The present invention relates to a kind of power grid security pick-up unit, especially a kind of cable cover(ing) circulation monitoring system.
Background technology
As everyone knows, the big deployment in underground of service cable of modern city generally uses cover plate, metal tube or pvc pipe as cable protective kit at present.At the Chinese city of current develop rapidly, be the building site everywhere, hook machine, ram engine possibly damage being embedded in underground service cable protective jacket at any time; In addition, cable cover(ing) is embedded in underground, and the testing staff can not have ocular estimate to monitor in real time, and sheath earth fault can not be to cause the main cause that the cable frequency of power cut increases and interruption duration is long by timely discovery.At present, the method that detects single core cable protective metal shell insulation status is mainly the insulation resistance method under the off-line state, and the method both wasted time and energy, and effect is also undesirable.Therefore, designing a kind of intelligentized cable sheath circulation monitoring system, is the present technical issues that need to address.
Summary of the invention
Technical matters to be solved by this invention provides a kind of intelligentized cable sheath circulation monitoring system.
