Direct current system earth fault detector with wireless communication function

The utility model discloses a direct current system earth fault detector with wireless communication function, include: signal generator, signal receiver and signal collector, signal collector and signal receiver are connected, signal receiver includes the signal amplification circuit who is connected mutually with signal collector, and signal amplification circuit is connected with filter circuit, AD conversion module, processing circuit and processor in proper order, the processor also is connected with liquid crystal display, the processor also is connected with the zigbee module, and the zigbee module is connected by sky wired -and zigbee wireless network mutually. The utility model discloses having the communication function, can utilizing it to carry out the communication, the tester who facilitates each place knows the test result in other places, and the more convenient dichotomy that utilizes carries out the localization of fault. Reduce tester's burden, improved efficiency of software testing, be favorable to the quick fault point that finds. In addition the zigbee module have the low power dissipation, with low costs, the time delay is short and data transmission characteristics reliably, has also guaranteed the accuracy that detects.
