Compared with the prior art, the fault indicator used for the 10KV overhead line has the advantages of great improvement of the judgment accuracy rate of short circuit and ground faults.

Description

The fault detector that is used for the 10KV pole line
Technical field
The present invention relates to a kind of fault detector, especially relate to a kind of fault detector of the 10KV of being used for pole line.
Background technology
Electric power line fault indicator originates from the Germany of nineteen seventies, and the purpose of inventing it is for the approach of indicating the power line short-circuit electric current to flow through, and helps people to find the trouble spot.China begins to introduce the development technology with the learning overseas indicator from the eighties, also has some products to put into operation successively.According to actual operating state, these products can reach the requirement except the detection to phase fault basically, singlephase earth fault are detected and judges to indicate also have many problems.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence a kind of fault detector that is used for the 10KV pole line that has improved the differentiation accuracy rate of short circuit and earth fault greatly to be provided.
The object of the invention can be realized through following technical scheme:
A kind of fault detector that is used for the 10KV pole line; It is characterized in that; Comprise induction electricity-fetching module, power management module, sampling module, reseting module, memory module, wireless communication module, main control module; Described main control module is connected with power management module, sampling module, reseting module, memory module, wireless communication module respectively, and described power management module is connected with the induction electricity-fetching module.
Described induction electricity-fetching module comprises sensor circuit, voltage regulator circuit, mu balanced circuit, and described sensor circuit, voltage regulator circuit, mu balanced circuit connect successively.
Described power management module realizes that power supply automaticallyes switch between battery power taking and induction power taking, and wakes main control module up.
Described main control module realizes that sampled data frequency analysis, fault diagnosis, communication protocol are resolved, the low-power consumption management.
The acquisition precision of described sampling module when bus current is 0 to 40A is 5 ‰.
Compared with prior art, the present invention can respond to power taking from bus; Can reach 5 ‰ measuring accuracy; Can communicate through 433MHz wireless communication module and main website; Can carry out frequency analysis, detect the even-order harmonic of injection accurately.Improved the differentiation accuracy rate of short circuit and earth fault greatly.
